Product Description
This is a 10 Watt Mono-crystalline Solar Panel and 12V Charger. The solar panel is waterproof. The working voltage for charging is 17.2V. If you need to use it to charge a car battery, you may need a charge controller to prevent the battery from overcharging. Connections included: alligator battery clamps. There are three types of Solar Cells on the market. All our Solar chargers use the best – Mono-Crystalline Solar Cells. Amorphous or Dual Junction Solar Glass are the cheapest but are only 7% energy efficient and have 5 years service life. They are big and heavy. Poly-Crystalline have 25 plus years of service life under direct sunlight and are 13% efficient. Mono-Crystalline have 25 plus years service life and are up to 20% efficient. This is the same type used in solar car racing. This type of solar cells is now in a worldwide shortage because only a few companies can manufacture this solar cells.
