A 3kW system typically needs a 2kW inverter, as your solar panel system should be roughly 50% larger than your inverter, as a general rule. This is largely due to the fact that in most UK locations, your solar panels won’t often reach their peak power rating, since our weather usually fails to match standard test conditions.
The number of solar panels required for a 3kW system depends on the wattage of the individual panels. Most residential solar panels today range from 300W to 450W. Higher wattage panels mean fewer units are needed to reach 3kW. For example, using 300W panels, you would need approximately 10 panels to generate 3kW.
For a 20kW solar system, you would need either 200 100-watt solar panels, 100 200-watt solar panels, 68 300-watt solar panels, or 50 400-watt solar panels. This is just how easy it is. We hope that this illustrates well how many solar panels you need for these differently-sized solar systems.
Three kilowatts of solar capacity could power a very small, off-grid home, but it’s likely too little to fully offset the energy use of the average American household. Due to the small size and output, a 3kW solar panel system could be ideal for powering a DIY project.
