Kaymak and Ercan İzgi and Ahmet Öztopal and Ahmet D. Şahin}, country = {}, institution = {}, abstract = {As known that efficiency of photovoltaic cells is not high as desired level. Efficiency of PVs could be improved by selecting convenient locations that have high solar irradiation, sunshine duration, mild temperature, low level air pollution and dust concentration. Additionally, some environmental parameters called derating factors effect to decrease PV efficiencies such as cloud, high temperature, aerosol optical depth, high dust concentration, shadow, snow, humidity etc. In this paper, all parameters that effect PV efficiency are considered in detail under climatic conditions of Istanbul. A 750 Wp PV system with measurement devices is constructed in Maslak campus of Istanbul Technical University.}, journal = {International Journal of Energy and Power Engineering}, volume = {4}, number = {8}, year = {2010}, pages = {1303 - 1307}, ee = {https://publications.waset.org/pdf/10643}, url = {https://publications.waset.org/vol/44}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 44, 2010}, }
