    This master's thesis describes the results of a solar system that tracks the movement of the Sun and a fixed system. Part of the task in the thesis was the software implementation in PVsyst, where a 5 kW residential photovoltaic power plant was taken as an example, along with the construction of a model for both a fixed system and a Sun-tracking system with a rated power of 1 W. The thesis also outlines the procedure for building the model itself and some steps in the software design process. All conducted measurements are documented in a table format, including measurement units and detailed descriptions. The code for running the model is included in the appendix. Ovaj diplomski rad opisuje rezultate solarnog sustava koji prati kretanje Sunca i fiksnog sustava.

    Authors: Glavić, Vedran;

    In this work, a solution is proposed to make the most of sunlight, which is a renewable source of energy. To make it, it is necessary to connect all the components to the Arduino board on which there is a program that gives commands to the components. The components include the solar panel, resistors, four photoresistors that are located at the corners of the solar panel and read where the most light is coming from, and two DC servo motors that precisely move the panel so that as much light as possible falls on it. A visual solution was created in the Tinkercad program. U ovom radu je predloženo rješenje kako bi se što više iskoristilo sunčeve svjetlosti koja je obnovljiv izvor energije. Za izradu je potrebno spojiti sve komponente na Arduino pločicu na kojoj se nalazi program koji daje naredbe komponentama. U komponente spadaju solarni panel, otpornici, četiri fotootpornika koji se nalaze na kutovima solarnog panela i očitavaju odakle dolazi najviše svjetlosti, te dva istosmjerna servo motora koja precizno pomiču panel tako da što više svjetlosti padne na njega. Napravljeno je vizualno rješenje u programu Tinkercad.

    Authors: Glavaš, Matea;

    The paper presents the characteristics of a passive office building i.e. what the building must be provided with in order to be a passive building. Some of the main impacts on energy consumption in the passive office building (orientation, shape, thermal insulation, windows and doors, ventilation systems, lighting, etc.) are also described. Analyzed is the experience of construction of such buildings in Croatia and worldwide as there is a limited practice of such construction in Croatia. Further, the difference in costs of building a passive office building compared and standard office building is shown, as well as energy savings that such a building achieves. Possible improvements are proposed in terms of even greater energy savings in the passive business building. In the methodological chapter, there is an analysis of techical high school curriculum related to the topic of this graduate thesis and a lesson plan. U ovom radu prikazane su karakteristike pasivne poslovne zgrade tj. što zgrada mora imati da bi bila pasivnom. Također su opisani neki od glavnih utjecaja na potrošnju energije u pasivnoj poslovnoj zgradi (orijentacija, oblik, toplinska izolacija, prozori i vrata, ventilacijski sustavi, rasvjeta i dr.). Analiziraju se iskustva gradnje takvih zgrada kod nas i u svijetu iako je vidljiva mala primjena takve gradnje u Hrvatskoj. Nadalje, prikazane su razlike u cijeni gradnje pasivne poslovne zgrade u odnosu na standardnu poslovnu zgradu pri samoj gradnji zgrade, ali i kolikoj uštedi energenata takva građevina doprinosi. Ponuđena su moguća unaprjeđenja u smislu još veće uštede energenata u pasivnoj poslovnoj zgradi. U metodičkom poglavlju nalazi se analiza nastavnog programa srednje strukovne škole vezane uz temu ovog diplomskog rada i pripremu za izvođenje nastave.

    Authors: Dundić, Ivona;

    Renewable energy sources, such as the Sun and wind, have a continuously increasing influence on the power system. With the development of awareness about climate change and the desire to reduce greenhouse gas emissions, there is an increase in the need for renewable sources in the production of electricity. However, electricity produced, for example, from solar panels depends on the insolation of the Sun, energy production in wind farms depends on the strength of the wind, which means that production from renewable sources is not always constant and represents a challenge in stabilizing the power system. On the other hand, solar and wind farms, depending on the installed power, are connected to the existing transmission and distribution network. However, this creates congestion and load on the existing power system network and at the same time requires significant investments in the existing power network infrastructure. The goal is to analyze how the energy system "behaves" after the implementation of a power plant based on renewable sources. Recent research has led to conclusions about the impact of electricity production from renewable sources on the environment and its implementation in the power system from the aspect of peak load monitoring and the generation of excess energy from existing power plants. Namely, renewable sources (sun, wind, etc.) are unpredictable and create problems in planning the production and consumption of electricity. Obnovljivi izvori energije, poput Sunca i vjetra, imaju kontinuirani porast utjecaja na elektroenergetski sustav. Razvojem svijesti o klimatskim promjenama te željom za smanjenjem emisija stakleničkih plinova, bilježi se porast potreba za obnovljivim izvorima u proizvodnji električne energije. Međutim, električna energija proizvedena npr. iz solarnih panela ovisi o insolaciji Sunca, proizvodnja energije u vjetroelektranama ovisi o jakosti vjetra, što znači da proizvodnja iz obnovljivih izvora nije uvijek konstantna i predstavlja izazov u stabilizaciji elektroenergetskog sustava. S druge strane, sunčane i vjetroelektrane, ovisno o instaliranoj snazi, priključuju se na postojeću prijenosnu i distributivnu mrežu. Ali, to stvara zagušenje i opterećenje postojeće mreže elektroenergetskog sustava te istovremeno zahtijeva znatna ulaganja u postojeću infrastrukturu elektroenergetske mreže. Cilj je analizirati kako se „ponaša“ energetski sustav nakon implementacije elektrane na obnovljive izvore. Istraživanjima u posljednje vrijeme donose se zaključci o utjecaju proizvodnje električne energije iz obnovljivih izvora na okoliš te implementaciji iste u elektroenergetski sustav s aspekta praćenja vršnog opterećenja i stvaranja viškova energije iz postojećih elektrana. Naime, obnovljivi izvori (Sunce, vjetar i dr.) nepredvidivi su te stvaraju probleme u planiranju proizvodnje i potrošnje električne energije.

    Authors: Rendulić, Mislav;

    In order to avoid the consequences of climate change and meet the obligations of the Paris Agreement, it is necessary to decarbonize the energy system and introduce renewable energy sources. This thesis will explain the calculation of potential energy from photovoltaic systems installed on all available facilities. In addition, the procedure for obtaining the aforementioned data and the tools used to obtain it will be elaborated in detail. In order to use the newly obtained resources, 5 different decarbonization scenarios were created, each applying the newly generated electricity in a different way. The scenarios are then compared based on the reduction of CO2 emissions and the increase of the total share of renewable energy sources in the system. Kako bi izbjegli posljedice klimatskih promjena te zadovoljili obaveze iz Pariškog sporazuma potrebna je dekarbonizacija energetskog sustava te uvođenje obnovljivih izvora energije. U radu će biti objašnjeno izračunavanje potencijalne energije iz fotonaponskih sustava instaliranih na svim raspoloživim objektima. Uz to, detaljno će biti i razrađena procedura dobivanja navedenih podataka te alati kojima su isti dobiveni. Kako bi se iskoristili novo dobiveni resursi, izrađeno je 5 različitih scenarija dekarbonizacije od kojih svaki ima posebnu primjenu novonastale električne energije. Scenariji se nakon toga uspoređuju na temelju smanjenja emisije CO2 i povećanja ukupnog udjela obnovljivih izvora energije u sustavu.

    Authors: Nemarnik, Luka;

    Ovaj završni rad se bavi konstrukcijom sustava nosača solarnih panela koji kod instalacije omogućava dodatno podešavanje položaja radi dobivanja optimalnog kuta nagiba, a time i postizanje maksimalne moguće efikasnosti pretvorbe energije. Konstrukciji je prethodio kratak uvid u procese iskorištavanja solarne energije, u kojemu se uspoređuju tipovi solarnih panela prema vrsti ćelija, analizira se utjecaj orijentacije panela na efikasnost pretvorbe energije i opisane su moguće pozicije montaže sustava solarnih panela. Nakon toga slijedi pregled postojećih rješenja, te razmatranje mogućih varijanti sustava nosača uz rješavanje konstrukcijskih zahtjeva. Naposljetku, odabrano je konstrukcijsko rješenje i dat proračun kritičnih komponenti uslijed opterećenja težinom samog sustava panela uz dodatno opterećenje zbog djelovanja vanjskih utjecaja kao što su snijeg i vjetar. Rad je popraćen potrebnom tehničkom dokumentacijom za izradu svih nestandardnih dijelova, te sklopnog crteža montiranog sustava. This final thesis deals with design of the solar panel mounts which allows additional position adjustment during installation in order to achieve the optimal angle of inclination, and thus the maximum possible efficiency of energy conversion. Design was preceded by a brief insight into the processes of solar energy utilization, which compares the types of solar panels by photovoltaic cell type, analyzes the impact of panel orientation on energy conversion efficiency and describes possible locations for installation. The following is an overview of existing solutions, and consideration of possible variants of the system considering technical requirements. In the end, the concept was selected and the calculations of critical components due to the load of system weight with additional load due to external influences such as snow and wind are given. The paper also includes necessary technical documentation for the manufacturing of all non-standard parts, and the assembly drawing of the installed system.

    Authors: Kopajtić, Luka;

    This study extensively explores the key aspects of implementing solar systems as a sustainable energy source through conceptual design. The analysis begins with the selection of solar panels, utilizing solar insolation and panel characteristics for precise dimensioning. The choice of inverters is also examined, emphasizing the relationship between the solar system's power and the inverter. The construction of the solar system and its dimensions are outlined. Financial analysis is crucial for assessing cost-effectiveness. Focusing on models of purchasing electricity generated by the solar system, scenarios are differentiated for buyers with self-production, users of self-supply facilities, and privileged producers, depicted through graphical representation highlighting key differences between models. Through the methods of Internal Rate of Return (IRR) and Net Present Value (NPV), the economic sustainability of the investment is evaluated. Graphs illustrating gradual cost reduction over time and comparisons between different buyer models are provided. Environmental impact analysis is a pivotal part of this research. CO2 emissions during the production and installation of the system are estimated and compared with emissions from conventional energy sources. The reduction of CO2 emissions through green energy production is emphasized, and the time required for carbon footprint neutrality of the solar system is calculated. This study offers profound insights into the technical, financial, and ecological aspects of applying solar systems as a sustainable alternative in the energy sector. A thoughtful approach to dimensioning, economic analysis, and environmental impact analysis collectively contribute to understanding the comprehensive benefits and challenges of utilizing solar systems in modern energy transitions. U ovom istraživanju detaljno su razmotreni ključni aspekti primjene solarnih sustava kao održivog izvora energije primjenom idejnog rješenja. Analiza je započela odabirom solarnih panela, gdje je koristila sunčevu insolaciju i karakteristike panela za precizno dimenzioniranje. Odabir izmjenjivača (invertera) također je istražen, s naglaskom na odnos snage solarnog sustava i invertera. Izvedena je konstrukcija solarnog sustava i njene dimenzije. Financijska analiza je ključna u prosuđivanju isplativosti. Usredotočujući se na modele otkupa električne energije proizvedene solarnim sustavom, razlikovani su scenariji kupca s vlastitom proizvodnjom, kupca korisnika postrojenja za samoopskrbu i povlaštenog proizvođača putem grafičkog prikaza koji nam ukazuje na ključne razlike između modela. Kroz metode interne stope prinosa (IRR) i neto sadašnje vrijednosti (NPV), ocijenjena je ekonomska održivost investicije. Prikazani su i grafikoni koji ilustriraju postupno smanjenje troškova s vremenom te usporedbe između različitih modela kupaca. Analiza utjecaja na okoliš bila je ključan dio istraživanja. Emisija CO2 pri proizvodnji i instalaciji sustava procijenjena je te uspoređena s emisijom električne energije iz konvencionalnih izvora. Ovdje je istaknuto smanjenje emisije CO2 putem proizvodnje zelene energije i proračunato vrijeme potrebno za neutralizaciju karbonskog otiska solarnog sustava. Ovo istraživanje pruža dubok uvid u tehničke, financijske i ekološke aspekte primjene solarnih sustava kao održive alternative u energetskom sektoru. Promišljeni pristup dimenzioniranju, ekonomska analiza i analiza utjecaja na okoliš zajedno doprinose razumijevanju sveobuhvatnih prednosti i izazova korištenja solarnih sustava u modernim energetskim tranzicijama.

    Authors: Grgić, Niko;

    Prior to installing a solar power plant, it is necessary to make a cost-effectiveness analysis in order to select the optimal power of the panels. The calculation is based on the insolation, slope, orientation and total power of the photovoltaic panels. The cost-effectiveness of a photovoltaic power plant can be increased by installing a battery storage. The topic of this diploma thesis is sizing and designing solar panels and battery on a given building, and providing an economic evaluation of the project. Prije instalacije solarnih panela, potrebno je izraditi analizu isplativosti kako bi se odabrala optimalna količina samih panela. Izračun se radi na temelju osunčanosti, nagiba, usmjerenja i ukupne snage fotonaponskih panela. Isplativost fotonaponske elektrane može se povećati ugradnjom baterijskog spremnika. Diplomski zadatak je dimenzionirati i projektirati solarne panele i bateriju na zadanoj zgradi, te konačno odraditi ekonomsku ocjenu tog projekta.

    Authors: Penić, Andrea;

    In order to ensure a better standard of living, and increase the quality of life, it is necessary to change the way of life as we know today. It is known that the energy is required for the normal functioning of all life on earth and one way to improve the quality of life is through the use of renewable energy sources that can be used indefinitely in suitable weather conditions. Solar energy, as one of the renewable energy sources, represents a long-term solution to the ever-growing demand for energy. The geographical position, physical availability for the installation of solar systems and the annual average of sunny hours are some of the positive sides for the use of solar energy in the Republic of Croatia. Thesis topic is to compare a solar panel that automatically rotates according to the position of the Sun with fixed solar panel. The data obtained by the measurement will be stored in a database and the user will be able to use the "ThingSpeak" application to access the same to be able check the voltage obtained from the solar panels. The aim of this paper is, to conclude according to the obtained data, which construction is more economical, more cost-effective, more efficient and provides higher voltage. Kako bi se osigurao bolji životni standard, te povećala kvaliteta života, potrebno je promijeniti način života koji danas poznajemo. Poznato je da je energija potrebna za normalno funkcioniranje cjelokupnog života na zemlji, te jedan od načina kojim bi se poboljšala kvaliteta života je kroz upotrebu obnovljivih izvora energije koji se mogu neograničeno iskorištavati u odgovarajućim vremenskim uvjetima. Sunčeva energija, kao jedan od obnovljivih izvora, predstavlja dugoročno rješenje za neprestanu rastuću potražnju za energijom. Geografski položaj, fizička raspoloživost za postavljanje solarnih sustava i godišnji prosjek sunčanih sati, neke su od prednosti za korištenje sunčeve energije u Republici Hrvatskoj. Tema diplomskog rada je usporediti solarni panel koji se automatski rotira prema položaju Sunca sa fiksno postavljenim solarnim panelom. Podaci koji će se dobiti mjerenjem, pohraniti će se u bazu podataka i korisnik će pomoću aplikacije „ThingSpeak“ moći pristupiti istima kako bi se provjerio napon koji se dobiva iz solarnih panela. Cilj rada je prema dobivenim podacima zaključiti koja konstrukcija je ekonomičnija, isplativija, efikasnija i daje veći napon.

    Authors: Klanac, Marko;

    Razvoj moderne tehnologije doveo je do značajnog porasta primjene solarne energije iskorištavanjem Sunca. Kako bi se bolje iskoristila Sunčeva energija, moguće je solarni panel montirati na sustav za praćenje položaja Sunca (engl. solar tracker). Takvi uređaji koji služe za praćenje Sunca, pomiču panel kako bi isti bio okomito postavljen na upad Sunčevih zraka. Glavna ideja ovog rada je opis, izrada te realizacija sustava za praćenje položaja Sunca uz pomoć Arduino Uno mikrokontrolera i bluetooth modula koji puni sustav pomoću panela odnosno Sunčeve energije. The development of modern technology has led to a significant increase in the use of solar energy using the Sun. In order to make better use of solar energy, it is possible to mount the solar panel on a solar tracker system. Such devices, which are used to monitor the Sun, move the panel so that it is placed perpendicular to the intrusion of the Sun's rays. The main idea of this work is to show development and implementation of Solar Tracking with the help of Arduino Uno microcontroller and bluetooth that charges the system using panels or solar energy.

    Authors: Krajinović, Marko;

    This master's thesis describes the results of a solar system that tracks the movement of the Sun and a fixed system. Part of the task in the thesis was the software implementation in PVsyst, where a 5 kW residential photovoltaic power plant was taken as an example, along with the construction of a model for both a fixed system and a Sun-tracking system with a rated power of 1 W. The thesis also outlines the procedure for building the model itself and some steps in the software design process. All conducted measurements are documented in a table format, including measurement units and detailed descriptions. The code for running the model is included in the appendix. Ovaj diplomski rad opisuje rezultate solarnog sustava koji prati kretanje Sunca i fiksnog sustava. Dio zadatka u diplomskom radu je bio softverski u programu PVsyst, u kojem je za primjer uzeta fotonaponska elektrana na kući nazivne snage 5 kW i izrada makete fiksnog i sustava koji prati kretanje Sunca snage 1 W. Također je u diplomskom radu opisan i postupak izrade same makete i neki koraci projektiranja u softveru. Sva izvršena mjerenja su zapisana u tablici s mjernim jedinicama i detaljnim opisom. U prilogu se nalazi kod za pokretanje makete

    In this work, a solution is proposed to make the most of sunlight, which is a renewable source of energy. To make it, it is necessary to connect all the components to the Arduino board on which there is a program that gives commands to the components. The components include the solar panel, resistors, four photoresistors that are located at the corners of the solar panel and read where the most light is coming from, and two DC servo motors that precisely move the panel so that as much light as possible falls on it. A visual solution was created in the Tinkercad program. U ovom radu je predloženo rješenje kako bi se što više iskoristilo sunčeve svjetlosti koja je obnovljiv izvor energije. Za izradu je potrebno spojiti sve komponente na Arduino pločicu na kojoj se nalazi program koji daje naredbe komponentama. U komponente spadaju solarni panel, otpornici, četiri fotootpornika koji se nalaze na kutovima solarnog panela i očitavaju odakle dolazi najviše svjetlosti, te dva istosmjerna servo motora koja precizno pomiču panel tako da što više svjetlosti padne na njega. Napravljeno je vizualno rješenje u programu Tinkercad.

    Authors: Glavaš, Matea;

    The paper presents the characteristics of a passive office building i.e. what the building must be provided with in order to be a passive building. Some of the main impacts on energy consumption in the passive office building (orientation, shape, thermal insulation, windows and doors, ventilation systems, lighting, etc.) are also described. Analyzed is the experience of construction of such buildings in Croatia and worldwide as there is a limited practice of such construction in Croatia. Further, the difference in costs of building a passive office building compared and standard office building is shown, as well as energy savings that such a building achieves. Possible improvements are proposed in terms of even greater energy savings in the passive business building. In the methodological chapter, there is an analysis of techical high school curriculum related to the topic of this graduate thesis and a lesson plan. U ovom radu prikazane su karakteristike pasivne poslovne zgrade tj. što zgrada mora imati da bi bila pasivnom. Također su opisani neki od glavnih utjecaja na potrošnju energije u pasivnoj poslovnoj zgradi (orijentacija, oblik, toplinska izolacija, prozori i vrata, ventilacijski sustavi, rasvjeta i dr.). Analiziraju se iskustva gradnje takvih zgrada kod nas i u svijetu iako je vidljiva mala primjena takve gradnje u Hrvatskoj. Nadalje, prikazane su razlike u cijeni gradnje pasivne poslovne zgrade u odnosu na standardnu poslovnu zgradu pri samoj gradnji zgrade, ali i kolikoj uštedi energenata takva građevina doprinosi. Ponuđena su moguća unaprjeđenja u smislu još veće uštede energenata u pasivnoj poslovnoj zgradi. U metodičkom poglavlju nalazi se analiza nastavnog programa srednje strukovne škole vezane uz temu ovog diplomskog rada i pripremu za izvođenje nastave.

    Authors: Dundić, Ivona;

    Renewable energy sources, such as the Sun and wind, have a continuously increasing influence on the power system. With the development of awareness about climate change and the desire to reduce greenhouse gas emissions, there is an increase in the need for renewable sources in the production of electricity. However, electricity produced, for example, from solar panels depends on the insolation of the Sun, energy production in wind farms depends on the strength of the wind, which means that production from renewable sources is not always constant and represents a challenge in stabilizing the power system. On the other hand, solar and wind farms, depending on the installed power, are connected to the existing transmission and distribution network. However, this creates congestion and load on the existing power system network and at the same time requires significant investments in the existing power network infrastructure. The goal is to analyze how the energy system "behaves" after the implementation of a power plant based on renewable sources. Recent research has led to conclusions about the impact of electricity production from renewable sources on the environment and its implementation in the power system from the aspect of peak load monitoring and the generation of excess energy from existing power plants. Namely, renewable sources (sun, wind, etc.) are unpredictable and create problems in planning the production and consumption of electricity. Obnovljivi izvori energije, poput Sunca i vjetra, imaju kontinuirani porast utjecaja na elektroenergetski sustav. Razvojem svijesti o klimatskim promjenama te željom za smanjenjem emisija stakleničkih plinova, bilježi se porast potreba za obnovljivim izvorima u proizvodnji električne energije. Međutim, električna energija proizvedena npr. iz solarnih panela ovisi o insolaciji Sunca, proizvodnja energije u vjetroelektranama ovisi o jakosti vjetra, što znači da proizvodnja iz obnovljivih izvora nije uvijek konstantna i predstavlja izazov u stabilizaciji elektroenergetskog sustava. S druge strane, sunčane i vjetroelektrane, ovisno o instaliranoj snazi, priključuju se na postojeću prijenosnu i distributivnu mrežu. Ali, to stvara zagušenje i opterećenje postojeće mreže elektroenergetskog sustava te istovremeno zahtijeva znatna ulaganja u postojeću infrastrukturu elektroenergetske mreže. Cilj je analizirati kako se „ponaša“ energetski sustav nakon implementacije elektrane na obnovljive izvore. Istraživanjima u posljednje vrijeme donose se zaključci o utjecaju proizvodnje električne energije iz obnovljivih izvora na okoliš te implementaciji iste u elektroenergetski sustav s aspekta praćenja vršnog opterećenja i stvaranja viškova energije iz postojećih elektrana. Naime, obnovljivi izvori (Sunce, vjetar i dr.) nepredvidivi su te stvaraju probleme u planiranju proizvodnje i potrošnje električne energije.

    Authors: Rendulić, Mislav;

    In order to avoid the consequences of climate change and meet the obligations of the Paris Agreement, it is necessary to decarbonize the energy system and introduce renewable energy sources. This thesis will explain the calculation of potential energy from photovoltaic systems installed on all available facilities. In addition, the procedure for obtaining the aforementioned data and the tools used to obtain it will be elaborated in detail. In order to use the newly obtained resources, 5 different decarbonization scenarios were created, each applying the newly generated electricity in a different way. The scenarios are then compared based on the reduction of CO2 emissions and the increase of the total share of renewable energy sources in the system. Kako bi izbjegli posljedice klimatskih promjena te zadovoljili obaveze iz Pariškog sporazuma potrebna je dekarbonizacija energetskog sustava te uvođenje obnovljivih izvora energije. U radu će biti objašnjeno izračunavanje potencijalne energije iz fotonaponskih sustava instaliranih na svim raspoloživim objektima. Uz to, detaljno će biti i razrađena procedura dobivanja navedenih podataka te alati kojima su isti dobiveni. Kako bi se iskoristili novo dobiveni resursi, izrađeno je 5 različitih scenarija dekarbonizacije od kojih svaki ima posebnu primjenu novonastale električne energije. Scenariji se nakon toga uspoređuju na temelju smanjenja emisije CO2 i povećanja ukupnog udjela obnovljivih izvora energije u sustavu.

    Authors: Nemarnik, Luka;

    Ovaj završni rad se bavi konstrukcijom sustava nosača solarnih panela koji kod instalacije omogućava dodatno podešavanje položaja radi dobivanja optimalnog kuta nagiba, a time i postizanje maksimalne moguće efikasnosti pretvorbe energije. Konstrukciji je prethodio kratak uvid u procese iskorištavanja solarne energije, u kojemu se uspoređuju tipovi solarnih panela prema vrsti ćelija, analizira se utjecaj orijentacije panela na efikasnost pretvorbe energije i opisane su moguće pozicije montaže sustava solarnih panela. Nakon toga slijedi pregled postojećih rješenja, te razmatranje mogućih varijanti sustava nosača uz rješavanje konstrukcijskih zahtjeva. Naposljetku, odabrano je konstrukcijsko rješenje i dat proračun kritičnih komponenti uslijed opterećenja težinom samog sustava panela uz dodatno opterećenje zbog djelovanja vanjskih utjecaja kao što su snijeg i vjetar. Rad je popraćen potrebnom tehničkom dokumentacijom za izradu svih nestandardnih dijelova, te sklopnog crteža montiranog sustava. This final thesis deals with design of the solar panel mounts which allows additional position adjustment during installation in order to achieve the optimal angle of inclination, and thus the maximum possible efficiency of energy conversion. Design was preceded by a brief insight into the processes of solar energy utilization, which compares the types of solar panels by photovoltaic cell type, analyzes the impact of panel orientation on energy conversion efficiency and describes possible locations for installation. The following is an overview of existing solutions, and consideration of possible variants of the system considering technical requirements. In the end, the concept was selected and the calculations of critical components due to the load of system weight with additional load due to external influences such as snow and wind are given. The paper also includes necessary technical documentation for the manufacturing of all non-standard parts, and the assembly drawing of the installed system.

    Authors: Kopajtić, Luka;

    This study extensively explores the key aspects of implementing solar systems as a sustainable energy source through conceptual design. The analysis begins with the selection of solar panels, utilizing solar insolation and panel characteristics for precise dimensioning. The choice of inverters is also examined, emphasizing the relationship between the solar system's power and the inverter. The construction of the solar system and its dimensions are outlined. Financial analysis is crucial for assessing cost-effectiveness. Focusing on models of purchasing electricity generated by the solar system, scenarios are differentiated for buyers with self-production, users of self-supply facilities, and privileged producers, depicted through graphical representation highlighting key differences between models. Through the methods of Internal Rate of Return (IRR) and Net Present Value (NPV), the economic sustainability of the investment is evaluated. Graphs illustrating gradual cost reduction over time and comparisons between different buyer models are provided. Environmental impact analysis is a pivotal part of this research. CO2 emissions during the production and installation of the system are estimated and compared with emissions from conventional energy sources. The reduction of CO2 emissions through green energy production is emphasized, and the time required for carbon footprint neutrality of the solar system is calculated. This study offers profound insights into the technical, financial, and ecological aspects of applying solar systems as a sustainable alternative in the energy sector. A thoughtful approach to dimensioning, economic analysis, and environmental impact analysis collectively contribute to understanding the comprehensive benefits and challenges of utilizing solar systems in modern energy transitions. U ovom istraživanju detaljno su razmotreni ključni aspekti primjene solarnih sustava kao održivog izvora energije primjenom idejnog rješenja. Analiza je započela odabirom solarnih panela, gdje je koristila sunčevu insolaciju i karakteristike panela za precizno dimenzioniranje. Odabir izmjenjivača (invertera) također je istražen, s naglaskom na odnos snage solarnog sustava i invertera. Izvedena je konstrukcija solarnog sustava i njene dimenzije. Financijska analiza je ključna u prosuđivanju isplativosti. Usredotočujući se na modele otkupa električne energije proizvedene solarnim sustavom, razlikovani su scenariji kupca s vlastitom proizvodnjom, kupca korisnika postrojenja za samoopskrbu i povlaštenog proizvođača putem grafičkog prikaza koji nam ukazuje na ključne razlike između modela. Kroz metode interne stope prinosa (IRR) i neto sadašnje vrijednosti (NPV), ocijenjena je ekonomska održivost investicije. Prikazani su i grafikoni koji ilustriraju postupno smanjenje troškova s vremenom te usporedbe između različitih modela kupaca. Analiza utjecaja na okoliš bila je ključan dio istraživanja. Emisija CO2 pri proizvodnji i instalaciji sustava procijenjena je te uspoređena s emisijom električne energije iz konvencionalnih izvora. Ovdje je istaknuto smanjenje emisije CO2 putem proizvodnje zelene energije i proračunato vrijeme potrebno za neutralizaciju karbonskog otiska solarnog sustava. Ovo istraživanje pruža dubok uvid u tehničke, financijske i ekološke aspekte primjene solarnih sustava kao održive alternative u energetskom sektoru. Promišljeni pristup dimenzioniranju, ekonomska analiza i analiza utjecaja na okoliš zajedno doprinose razumijevanju sveobuhvatnih prednosti i izazova korištenja solarnih sustava u modernim energetskim tranzicijama.

    Authors: Grgić, Niko;

    Prior to installing a solar power plant, it is necessary to make a cost-effectiveness analysis in order to select the optimal power of the panels. The calculation is based on the insolation, slope, orientation and total power of the photovoltaic panels. The cost-effectiveness of a photovoltaic power plant can be increased by installing a battery storage. The topic of this diploma thesis is sizing and designing solar panels and battery on a given building, and providing an economic evaluation of the project. Prije instalacije solarnih panela, potrebno je izraditi analizu isplativosti kako bi se odabrala optimalna količina samih panela. Izračun se radi na temelju osunčanosti, nagiba, usmjerenja i ukupne snage fotonaponskih panela. Isplativost fotonaponske elektrane može se povećati ugradnjom baterijskog spremnika. Diplomski zadatak je dimenzionirati i projektirati solarne panele i bateriju na zadanoj zgradi, te konačno odraditi ekonomsku ocjenu tog projekta.

    Authors: Penić, Andrea;

    In order to ensure a better standard of living, and increase the quality of life, it is necessary to change the way of life as we know today. It is known that the energy is required for the normal functioning of all life on earth and one way to improve the quality of life is through the use of renewable energy sources that can be used indefinitely in suitable weather conditions. Solar energy, as one of the renewable energy sources, represents a long-term solution to the ever-growing demand for energy. The geographical position, physical availability for the installation of solar systems and the annual average of sunny hours are some of the positive sides for the use of solar energy in the Republic of Croatia. Thesis topic is to compare a solar panel that automatically rotates according to the position of the Sun with fixed solar panel. The data obtained by the measurement will be stored in a database and the user will be able to use the "ThingSpeak" application to access the same to be able check the voltage obtained from the solar panels. The aim of this paper is, to conclude according to the obtained data, which construction is more economical, more cost-effective, more efficient and provides higher voltage. Kako bi se osigurao bolji životni standard, te povećala kvaliteta života, potrebno je promijeniti način života koji danas poznajemo. Poznato je da je energija potrebna za normalno funkcioniranje cjelokupnog života na zemlji, te jedan od načina kojim bi se poboljšala kvaliteta života je kroz upotrebu obnovljivih izvora energije koji se mogu neograničeno iskorištavati u odgovarajućim vremenskim uvjetima. Sunčeva energija, kao jedan od obnovljivih izvora, predstavlja dugoročno rješenje za neprestanu rastuću potražnju za energijom. Geografski položaj, fizička raspoloživost za postavljanje solarnih sustava i godišnji prosjek sunčanih sati, neke su od prednosti za korištenje sunčeve energije u Republici Hrvatskoj. Tema diplomskog rada je usporediti solarni panel koji se automatski rotira prema položaju Sunca sa fiksno postavljenim solarnim panelom. Podaci koji će se dobiti mjerenjem, pohraniti će se u bazu podataka i korisnik će pomoću aplikacije „ThingSpeak“ moći pristupiti istima kako bi se provjerio napon koji se dobiva iz solarnih panela. Cilj rada je prema dobivenim podacima zaključiti koja konstrukcija je ekonomičnija, isplativija, efikasnija i daje veći napon.

    Authors: Klanac, Marko;

    Razvoj moderne tehnologije doveo je do značajnog porasta primjene solarne energije iskorištavanjem Sunca. Kako bi se bolje iskoristila Sunčeva energija, moguće je solarni panel montirati na sustav za praćenje položaja Sunca (engl. solar tracker). Takvi uređaji koji služe za praćenje Sunca, pomiču panel kako bi isti bio okomito postavljen na upad Sunčevih zraka. Glavna ideja ovog rada je opis, izrada te realizacija sustava za praćenje položaja Sunca uz pomoć Arduino Uno mikrokontrolera i bluetooth modula koji puni sustav pomoću panela odnosno Sunčeve energije. The development of modern technology has led to a significant increase in the use of solar energy using the Sun. In order to make better use of solar energy, it is possible to mount the solar panel on a solar tracker system. Such devices, which are used to monitor the Sun, move the panel so that it is placed perpendicular to the intrusion of the Sun's rays. The main idea of this work is to show development and implementation of Solar Tracking with the help of Arduino Uno microcontroller and bluetooth that charges the system using panels or solar energy.
