Monocrystalline vs. Polycrystalline Solar Panels
Polycrystalline panels have lower ratings, between 15% and 17%. This means monocrystalline panels can use more of the sun''s energy. Monocrystalline panels also have a higher power output. They can produce at least 320 watts, sometimes up to 375 watts or more. Polycrystalline panels usually make 240 to 300 watts.
