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
used in photovoltaic panels which has two kinds of polycrystalline and monocrystalline silicon, LED street light, 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. Solar-thermal products is refers to the solar water heater, solar heating system ( General application is 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.
