Poor households have photovoltaic power generation loans at home, and they can also borrow money. Poor households have obtained photovoltaic power generation loans and are repaying them on time, indicating that the lenders have good credit and strong repayment ability, which will be beneficial to the subsequent loan approval. In addition, the photovoltaic power generation loan project itself will also help poor households to increase their income and improve their living conditions, and the positive performance in this regard may also have a positive impact on subsequent loan applications. Photovoltaic power generation is a process of converting light energy into electric energy by using solar energy. Photovoltaic power generation system is mainly composed of photovoltaic cells, which are semiconductor devices that can directly convert sunlight into electric energy.
