How many MWh of solar energy comes from a MW of solar panels?
On average, across the US, the capacity factor of solar is 24.5%. This means that solar panels will generate 24.5% of their potential output, assuming the sun shone perfectly brightly 24 hours a day. 1 megawatt (MW) of solar panels will generate 2,146 megawatt hours (MWh) of solar energy per year.
Solar panels work for as many hours of the day as there is sunlight, which is the main factor affecting overall energy production. The strength of the sun''s rays varies a great deal throughout the day, weakest in early morning and late evening, and strongest during the 4 hours in the middle of the day.
Because solar panels don''t work in isolation, it''s important to first understand a couple of key concepts: solar panel efficiency and how a photovoltaic (PV) solar system works. Solar panels capture the sun''s photons -- little packets of energy – and turn them into electricity. To capture as much sunlight as possible you need an efficient ...
