Design of a photovoltaic system for a rural house

In this work we have tried to supply electrical demand of a rural house without connection to national grid, using day to day necessary appliances, by photovoltaic system. Primarily electrical consumption of all appliances were estimated using energy charts, by considering the working time, total daily energy consumption was calculated. The four year registered data at MERC was obtained using a pyranometer, where time of radiation, least radiation intensity was obtained from the registered data, where from them calculations for electrical supply was used, with regard to radiation time, daily electrical consumption, number of photovoltaic panels, their related accessories were calculated. Calculations indicate that it is required to have 11 photovoltaic panels with 45W power, 3 inverters of 700W and 2, 12V and 120Ah batteries. Results can be used for rural houses, where due to long distances providing electricity to them from the national electric network would be very expensive.
