What is a PV power system?
It is a system which consists of solar panels, power-charging and -discharging controllers, a solar inverter, a tester, and other computer and mobile electronic devices, storage batteries, and other assistant power geenration devices. It works to generate electricity by absorbing sunlight and converts it into home use electricity.

What are advantages of the system?
1.It doesn’t have moving components that often produce lots of noise. It is home-friendly.
2.It is environment-friendly and will never emit polluted air or water.
3.It doesn’t need a procedure which needs biofuels to power itself.
4.It is easy to repair and maintain, and so you don’t have to spend so much money on its repair and maintenance.
5.It is reliable and stable.
6.The solar panels all have a long lifespan and they often span up to 25 years.
7. You can easily expand your scale of power generation according to your individual demands.

Use of the PV power system
It is now a widely used system that can be generally divided into two types: stand alone and grid-tie power generation systems. So far, developed countries such as the UK and the US have begun to install the grid-tie power system in their cities. China and Japan are now following this fashion too. They are mainly building residential rooftop PV power systems and MW-level large-scale grid-tie power generation systems. It can be used in different areas, such as home, transport, communications, space and others.

Working principle
Although they have different sizes and forms, their working principle is the same. Generally speaking, it is a system that generates electricity from sunlight by its solar panels, and then charges the storage batteries through the control of the controller, or supplies the direct current load if the load requirement is satisfied. If there is no rich sunlight or if it is at night, controlled by a controller, electricity will be transmitted to the direct current load. If the electricity needs to be used in a house, the direct current must be converted by a solar inverter into alternating current.
