HOME / How many photovoltaic panels are needed for a 10 000 square meter roof - CAPTURED ENERGY SOLAR (PTY) LTDFor 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.
If you are using only 400-watt solar panels, you will need 13 400-watt solar panels for a 5kW solar system (13 × 400 watts is actually 5200 watts, so this is a 5.2kW system). Quite simple, right? You can also mix solar panels with different wattages.
Our solar professionals model different scenarios to find the right balance between system size and budget comfort. Installing solar panels on a roof with less than 10 years of remaining life is false economy.
Standard Efficiency Panels (350-400W) These panels represent the most budget-friendly solar options and work well for homes with ample roof space. Modern standard efficiency panels from quality manufacturers deliver reliable performance at lower upfront costs. For a typical 7 kW system, expect to need 18-20 panels in this category.
