This type utilizes the solar cells that have been made from a single large crystal of great purity, cut from bars. Such cells are the most effective type of solar panels.
The minus is that at the same time they are the most expensive ones. Their performance is a bit better in the conditions of low light (but be careful and don’t swallow different fraudulent advertising baits).
The average overall efficiency makes about 12-15%. The warranty for such panels is 20-25 years. Usually, they are blue-grey in their color. Also, they have a pretty uniform consistence.
