The calculation results show that:
National urban construction land area of 40503 Km2, distributed photovoltaic available area of about 19036.41 Km2, the north China, northeast China, east China, south China, southwest, northwest seven large area accounted for 13%, 11%, 34%, 14%, 12%, 10%, 12%, guangzhou city, guangdong province, which can be largest photovoltaic cells, about 839.89 Km2; The minimum area of photovoltaic cells can be installed in haidong city, qinghai province, about 2.82km2.
According to the experience of the industry according to the calculating average 10 square meters to install 1 kw distributed photovoltaic system, the national 31 provinces and cities in addition to Hong Kong, Macao and Taiwan accident in urban development of distributed photovoltaic resources amount to as much as 1903.46 GW.
Considering the region distributed photovoltaic development policy adjustments, the difference of regional economic development and uncertain factors such as photovoltaic technology development, design three kinds of development strength, were conservative development scenarios, namely the development intensity is 20%; Basic development scenario, namely the development intensity is 40%; The active development scenario is that the development intensity is 60%. In view of the above three scenario designs, the distributed pv installation potential of urban development in 31 provinces and cities across China is calculated under different development intensity. The calculation results show that, under the existing economic and technological conditions, the total amount of distributed photovoltaic installed capacity in the 31 provinces and cities in China is 380.73GW.
