How many rooftop solar photovoltaic power stations can be installed on the roofs of existing buildings in my country?
A set of data learned from the Chinese Academy of Building Research shows that my country’s existing building area is about 60 billion square meters. If it is installed at a ratio of 1:6, 10 billion square meters of photovoltaic can be installed, which is about 1500GW of installed capacity; at the same time, my country The annual new construction area is 2 billion square meters, and there are many mid-to-high-rise buildings. The installable photovoltaic area ratio is lower than that of existing buildings. If all are installed, the photovoltaic area will be nearly 140 million square meters, and the photovoltaic system installed capacity will be about 20GW.
According to estimates by brokerage agencies, BIPV’s annual potential roof area only includes approximately 1.23 billion square meters of renovated roofs + newly added roofs, corresponding to a market space of 1.3 trillion yuan.
