Nowadays, solar energy is the most commonly used green energy in China. With the rapid development of modern science and technology, the use of solar energy has gradually entered the public's vision and can be seen everywhere in daily life. Then, how about the cost performance of installing solar power supply system in families? Is it worth it?
Solar power supply system is mainly composed of solar panels, battery packs, controllers and pv connectors, which are mostly used to supply power to small equipment, such as solar street lights, solar monitoring, etc., in addition to small off-grid power stations, large solar power stations and so on. In the family, its main role is to power home appliances, so that according to the actual demand to select the number of solar panels installed power supply system can be, let's call it the family solar power supply system.
Talking about cost performance, the first thing we should consider is the advantages of installing solar power supply system at home. From a macro perspective, solar energy is a new energy, which is theoretically inexhaustible. As long as it is in the place where there is sunlight, it can generate electricity, and the use of solar energy will not cause pollution, so it is a clean energy. In practical terms, home solar power systems generate electricity for home use when the sun is shining, and can store excess electricity through a battery pack to provide power when the sun is not shining. In addition, it can also use the solar energy + municipal network. When the solar power supply is insufficient, it can be connected to the mains. When the mains power is suddenly suspended, it can be connected to the solar energy to ensure the normal use of household electricity.
