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.
You’ll typically need 22.85 square metres (m²) of roof space for a 3kW solar panel system. This takes into account the average height and width of a solar panel – which combine for a total size of around two square metres – plus the additional space installers tend to leave.
A 3kW Solar Panel setup produces approximately 12–15 kWh per day depending on sunlight exposure and panel efficiency. This size is ideal for households consuming around 300–400 kWh per month. It’s a scalable system that allows for easy future upgrades if your energy demand increases.
