A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces.
1. Mono-crystalline type: By far the highest efficiency in its type, mono-crystalline panels also has the highest level of expected life. The module efficiency can range from 16-18% (quite high for the industry standards).
2. Poly-crystalline type: Typical efficiency of Polycrystalline modules would range anywhere between 12-14%. With beautiful blue and black crystalline formation on the cells, these types of panels take the technology to higher aesthetic value.
