40 w photovoltaic investment how much polycrystalline silicon solar panels to the user
Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps.
solar street lamps use crystal silicon solar battery power supply, valve control sealed and maintenance-free battery ( Gel battery) Store electricity, high brightness led lamp as light source, controlled by the intelligent charging and discharging controller, to replace the traditional public power lighting lamps. The birth of the new energy into making solar street lamps, returned to the green earth. The definition of solar panels, solar panels
panel) Is a absorb sunlight through the photoelectric effect or photochemical effect directly or indirectly, convert solar energy into electrical energy device. Most solar panels are made of 'silicon' as the main material, but as a result of the manufacturing cost is high, its widespread use has some limitations. Compared with ordinary batteries and rechargeable batteries, solar cells is more energy saving and environmental protection green products. 40 polycrystalline silicon solar panels parameters: standard size: 818 mm long, 350 mm wide, thick 4. 18 v, 5 mm working voltage, working current: 1000 ma conversion efficiency: 20 - 24. 2% rated power: 40 w test standard: 1000 watts per square metre spectral AM1 temperature 25 ℃. Polycrystalline silicon solar panels feature: (540 1) In the United States imports of solar panels ( 2) Conversion efficiency can reach 20 - 24. 2% ( 3) Weak light sex good, strong stability, 4) USES the listed companies of polyester and EVA material ( 5) High strength and resistance to deformation printed circuit board ( Glass fiber board) 6. 40 polycrystalline silicon solar panels can be to 2. 0 mm, can be flexible customization according to the external dimension requirement.
