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.
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.
If you are using only 300-watt solar panels, you will need 17 300-watt solar panels for a 5kW solar system (17 × 300 watts is actually 5100 watts, so this is a 5.1kW system). 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).
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.
