Solar energy is sunlight energy through solar energy battery components to accept the sun radiation, convert light energy into electrical energy, and constantly to the
battery under the management of the controller, the controller in accordance with the procedure set electrical energy is released from the battery to the power supply
equipment.Divided into two large photovoltaic and thermal solar energy products.Used by photovoltaic panels has two kinds of polycrystalline and monocrystalline
silicon, the latter conversion rate higher.Pv systems with a solar roof power generation system, solar glass curtain wall power, large grid/off-grid power generation
system (such as the Tibetan yambajan engineering).In addition, there are solar street lamps, scenery complementary street lamps, solar lights, solar LED screen, solar
backpack, and so on.Hot product is refers to the solar water heater and solar heating system (usually) in the north.Used in solar water heater has several panels,
common is flat solar and vacuum tube solar two kinds, the former south use is more, the latter used more north.
