15 the difference is about 10 watts w per regular panel 270 w mono.
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.
For example if the efficiency of a monocrystalline cell is about 2 greater than the polycrystalline cell say 17 vs.
A solar cell panel has then a smaller solar active area compared to its total area than a single solar cell i e.
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.
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.
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.
The main difference between the two technologies is the type of silicon solar cell they use.
Space areas between the solar cells.
