When a government or financial institution provides a personal photovoltaic power generation project loan plan, the applicant needs to provide an ID card as identity verification. The installation of photovoltaic power plants needs to be registered for the record, and the surplus electricity can be sold to apply for state subsidies after entering the state grid. You must have ID cards, household registration books, real estate licenses and other related materials, and you also need to provide bank card numbers to receive subsidies and sales income.
