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.
GoGreenSolar offers high-performance panels that deliver power output between 335 to 405 watts. Whether you want to offset your energy bill partially or completely, we have solar kits to match your specific energy needs. Your budget often determines the size of the solar system you can afford. Solar panels are just one part of the equation.
For a typical 7 kW system, expect to need 18-20 panels in this category. Standard efficiency panels are ideal if you have a large, unobstructed south-facing roof and want to prioritize lower installation costs over maximum power density. They’ll deliver strong long-term performance and reliable energy production.
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 standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
