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 cell is now in a worldwide shortage because only a few companies can manufacture this solar cell.
