Differentiate Between Solar Panel And Solar Cell

Monocrystalline solar panels have solar cells made from a single crystal of silicon while polycrystalline solar panels have solar cells made from many silicon fragments melted together.

Differentiate between solar panel and solar cell.

The difference between solar cells and solar panels producing electricity for your home or business is a function of solar cells and solar panels working together. A cell on its own doesn t produce much power and a number of cells together need the protection and stability that the panel offers. All solar cells have both n type and p type with the great majority having one surface n type and one surface p type. The solar cells are actually contained within the solar panels with each part playing a specific role within the larger system which is called a photovoltaic system.

For example if the efficiency of a monocrystalline cell is about 2 greater than the polycrystalline cell say 17 vs. 15 the difference is about 10 watts w per regular panel 270 w mono. The main difference between the two technologies is the type of silicon solar cell they use. It is the junction between the n and the p type regions that creates the step in the energy levels that leads when illuminated to the 600 mv potential difference between the electrons entering the p type layer and leaving the n type layer.
