Analysis of technical efficiency, economic feasibility, and environmental impacts of using solar heating installations for buildings

The study idea includes the possibility of using solar energy to provide for heating a house in city Warsaw by examining systems available on market and simulating their performance comparing them based production volume with cost appropriateness climatic conditions area determine best way installing panels calculating optimal tilt azimuth angles. work methodology designing suitable system went two directions; first is thermal collector direct heat generation; while second photovoltaic generate electricity water heater. Then monitor impact conversion use terms efficiency ability this produce according economic feasibility, knowing financial returns versus costs traditional methods, environmental contribution reducing greenhouse gas emissions. All results were obtained through simulation RETScreen PVGIS software. showed that demand was 40% from collectors 43% panels.
