How to assess a solar panel

Panel Efficiency

The efficiency of a panel is the percentage of the energy in the sunlight that hits the panel surface which is successfully converted into electrical energy. Quality panels have an efficiency of at least 18%

Solar Panel Wattage

Wattage is a measure of the amount of power generated by the panel. The suns energy generates approximately 1,000 Watts per sq/m – so the Wattage of a panel is the area of the panel x the efficiency of the panel.
ie. 1000 x 1.6sqm x 20% = 320W
