The term solar panel is used colloquially for a Photo-voltaic (PV) module. A PV module is an assembly of Photo-voltaic cells mounted in a frame work for installation. Photo-voltaic cells use sunlight as a source of energy and generate direct current electricity. A collection of PV modules is called a PV Panel, and a system of Panels is an Array. Arrays of a photovoltaic system supply solar electricity to electrical equipment.
As per MNRE Standards, Solar Panels are warranted for
Difference between Mono and Polycrystalline Solar Panels
|Monocrystalline Solar Panels||Polycrystalline Solar Panels|
|They have the highest level of efficiency at 15-20%||Efficiency is only around 13-16% due to low levels of silicon purity.|
|They require less space compared to other types due to their high efficiency||The manufacturing process is cheaper and easier than the monocrystalline cells|
|The life of Solar Cells os longest because of it's purity||The life is shorter because of less Silicon and other doping materials.|
|They perform better in low levels of sunlight, making them ideal in cloudy conditions||Efficiency is less in shady/cloudy areas|
