Abstract
The large supermarket consumes 4,000kw to 6,000kwh / day of electricity, while the flat parking lot has a vast area of 500 to 1,000 cars (10,000 to 20,000㎡). Power generation by solar sheet of 350wh / 2㎡ / in about 4 to 5 hours is about 1.5kwh / sheet / day. Then, the required number of solar panels that can generate 5,000kwh / day is about 3,333, and the required laying area is about 7,000㎡. That is, it is possible if a vast parking lot is used. Assuming that capacity of the required storage battery is 48 hours, the implementation plan will be established by setting up the 10,000kWh battery and the 500kw inverter, and if the shortage is covered by such as the nighttime power of the electric power company.
