PV inverter is main component of any solar photovoltaic power plant. Efficiency of photovoltaic inverter depends upon mainly weather profile, which is not same always. To find out conversion efficiency of inverter, globally two weighted methods were introduced as EURO and CEC efficiency which are based on irradiation profile of Europe and California where as Indian irradiation profile is different from Europe and California. This paper is introducing new weighted factors for efficiency calculation as per irradiation profile in Indian. Where two zones are selected as North Zone (Rajasthan, Gujrat and Madhya Pradesh) and South Zone (Telangana, Andhra Pradesh, Karnataka and Chennai) named India-North-Efficiency & India-South-Efficiency as both regions have different Irradiation profile. These methods consider the irradiation distribution over the whole annual sunny time, impact of temperature and prioritize the range with various weight factors.
