With the sustained and rapid development of solar utilization technology and reduction of production cost, for many families, utilize household solar power system to supply family power becomes more and more realistic. According to the difference of networking ways, solar power system mainly include off-grid and grid system. Off-grid is the power generation system that totally independent of the public grid, without limitation of place, any user who need can install & use, so it is very suitable for no grid region to use. Tie grid is the system connect to the public grid, can realize complementary electricity use. Wealthy power can be delivered to the public grid. Due to the power demands of each family and organization have a great difference, the system capacity can be also diversified. Individual user, villa, enterprise can install personal solar-powered generator according to their actual power consumption. The installation project of PV system is a highly professional and complex work, so it must be put into use after professionals installing and commissioning.
　　Whether the off grid or tie grid, it is available for business or home. Off grid power generation system is mainly composed of solar panel arrays, battery, charging and discharging controller, inverter and other parts. It is a complete combination of solar power generation that can convert solar energy to electricity energy directly then convert electricity energy to chemical energy and stored in battery, or convert to electricity energy for load use when needed. It can be also convert direct current to alternating current for business and home. Tie grid generally do not need battery, the public grid is energy storage device, so it can greatly reduce the cost of the whole system. After installed the whole system, need no fuel in the running and will not produce any harmful materials and gases. All energy from sun radiation, it is a kind of clean and green energy.

Due to the installation of solar PV generation system is a highly professional and complex work, for the users often go out, a simple and practical home solar lighting system is particularly important, this is integrated household solar power generation device. The whole device is simple in structure, which is composed of solar panel and generator proper. The host utilizes an integral design, integrating the battery, controller and inverter, has a variety of output ports. Equipped with matching solar panel, no need commissioning can be used after installation. It is a kind of solar generator which is diversiform function, simple to use and easy to move. It is especially suitable for outdoor camping, outdoor agriculture and forestry, mountain villa, fishing-boat and the remote area of families without electricity, and is also available as the emergency power for frequent power cut-off families.
