How Many Solar Panels Do I Need For a 3000 Watt Inverter?
Inverter watt load / solar panel watt output + 10% = solar panel array. In this example we will use a 300 watt solar panel: 2500 / 300 = 8.3. 8 x 300 watts = 2400 watts. Add 10% and you get 2640 watts. Round that figure off to 2700 watts. 9 x 300 = 2700. A 9 x 300 watt solar array can run a 2500W inverter load, even with energy losses factored in.
