Sinoamigo lighting - Solar panel is the core part of solar lamps and lanterns, and it is also the part with the highest application value in solar lamps and lanterns. Its function is to convert the solar radiation energy into electric energy or send it to the battery for storage. Among most solar cells, monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells are more common and practical.
In solar lamps, a charge-discharge controller with excellent performance is essential. In order to prolong the service life of the battery, its charge and discharge conditions must be limited to prevent the battery from overcharging or deep charging. In places with large temperature differences, the qualified controller shall also have temperature compensation function.
