20watt 30watt 12V Solar Panel chargeingb Solar Traffic Signals Lights with 12v battery and 0.9m wire DC connecter

Poly Solar Cells

Efficient photoelectric conversion, stable performance

Unique etching process can increase the short-circuit current of the solar cell

Advanced PECVD technology provides well-proportioned navy blue silicon nitride anti-reflection velum:

Screen priting patterns are accurate and smoothness of the electrode is improved thus making the cell

easier for welding and laser cutting

SOLAR ELECTRIC POWER GENERATION

Solar Electric Power can be generated varying from 100 Watts small solar home systems to 100 MW Solar

Power Plants or sometimes more than that. The solar power systems are of two types; one is off-grid and

other is on-grid systems. In off-grid systems, the system has no link with Utility grid and components used in

Systems are Solar Panels, Charge Controllers, Inverters, Deep Cycle Batteries, mounting and electric

accessories. Solar Panels convert solar radiations into electric current and this current passes through

charge controllers which charges the battery by controlling current for the battery. Charge controllers

maintain control on charging the battery for its long life. So the DC power is stored in Batteries and this

stored energy is converted into AC Power to operate the AC appliances. The DC appliances can be

operated directly with the battery. So DC and AC load can be operated through a solar power system.
