Solar Panel Efficiency

All solar panels receive a nameplate power rating indicating the amount of power they produce under industry-standard test conditions. Most solar panels on the market have power ratings in the range of 200 to 350 watts.

A higher efficiency (%) means that the PV Panel will produce the rated output wattage of the given by the manufacturer in LESS area (per/sq.meter) than a lower efficiency (%) panel.

Solar Irradiance (determined by the where you are located on earth) determines the max amount of energy generated and Higher efficiency of a PV panel will not affect the 'Units' generated per day.

Monocrystalline Solar PV Panels have a Higher Efficiency (%) than Polycrystalline Solar PV modules and they are used in places where the area available for installation of panels is less than typically required. We'll talk more on that in a future post.
