Do you know about the three most popular types of solar energy currently on the market:

Off grid solar system , Solar grid tie system , On/Off grid solar hybrid system

Off grid solar power system :Solar system not only have solar power system function, but also have Utility complementary function. When main power off , the solar system can switch automatically to take use off solar power from battery to run load, When solar power not enough and power off , it can switch automatically to main power and connect with grid electricity take use of main power .at the same time charging battery. This is very suit for home use.

Solar grid tie system : The solar energy is directly connected to the grid and supplied to household loads. Excess electricity can be sold to grid companies. This system is suitable for countries with expensive electricity bills, where the government provides subsidies for electricity costs

Hybrid Solar System combines advantages of on grid solar system and off grid solar system.

It connects to grid, you can sell solar power to grid;

Also it has batteries backup, so solar power can be stored in batteries for night use or rainy days use.

If solar power is not enough, grid can charge batteries and supply power to your load
