All solar cells have both n type and p type with the great majority having one surface n type and one surface p type.
Differentiate between solar panel and solar cell.
The cells the panels and the array and the inverter all join forces to make up your solar power system with the cells as the basis as they perform the work of generating the electricity.
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.
15 the difference is about 10 watts w per regular panel 270 w mono.
A solar cell panel has then a smaller solar active area compared to its total area than a single solar cell i e.
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.
For example if the efficiency of a monocrystalline cell is about 2 greater than the polycrystalline cell say 17 vs.
Space areas between the solar cells.
The main difference between the two technologies is the type of silicon solar cell they use.
