In Hong Kong, the unused land should be used to maximize the use of assets. A solar power generation system is built on the roof of the warehouse/industrial and commercial building without occupying additional land, saving a lot of land resources. The current feed-in tariff price is about 5 to 3 yuan per kilowatt-hour of electricity. The economic benefits of photovoltaic power generation for a year on the roof of a medium-sized warehouse/industrial and commercial building are considerable.
