Distributed photovoltaic power stations make use of distributed resources. The stations are located close to users, converting solar energy into electrical power with a small installed capacity. The major profit model is "self-generation of power for self-use and access of surplus electricity quantity to power grids". The income comes from the on-grid price, while the cost includes device expense, maintenance, depreciation, etc.
Distributed PV systems can reutilize idle resources; corporate carbon emissions can be reduced, and the strain on power load can be relieved. Meanwhile, people can access cheap green electricity.
