A household solar power system refers to a small solar power system installed on an independent roof. It conforms to the trend of clean energy applications, and at the same time solves the problem of household electricity.

　　The household solar power generation system is installed on an independent roof, which is generally composed of solar cell modules, inverters, and brackets. Among them, there are three types of roofs that are very suitable.

　　(1) Sloping roof

　　Sloping roofs are generally more beautiful. Due to the large slope of the roof, rainwater is easy to drain, and the construction is simple and easy to repair.

　　Installing a solar power station on a sloping roof does not need to increase the bracket and calculate the inclination angle. During installation, it can be laid according to the inclination angle of the roof itself, and the installation capacity is not affected by the area. Due to the large slope, it can also achieve the effect of automatic cleaning.

　　(2) Flat roof

　　The roof slope is less than 5% (2.86 degrees) as a flat roof. The biggest advantage of installing a solar power system on a flat roof is heat insulation and cooling. It needs to determine the best inclination angle according to the geographical location of different regions and the actual situation. In order to ensure that the front row components do not block the rear row components, there must be a space between the two rows of components.

　　(3) Roof of sun room

　　The sun room is also called the glass room. It is a non-traditional building constructed with glass and metal frames to achieve the purpose of enjoying the sun and being close to nature.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　Solar power generation system with lithium battery energy storage system is a very promising clean energy.
