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.
You can also mix solar panels with different wattages. Example: For a 10 kW solar system, you can use 33 300-watt PV panels (9900 watts) + 1 100-watt solar panel to bring the total up to 10,000 watts or 10kW solar system. This is a 10kW solar system.
Complete 2025 Calculator & Planning Guide Location Impact is Massive: The same home using 1,000 kWh monthly could need just 16 panels in sunny Arizona but 22 panels in Massachusetts due to solar production ratios varying from 1.0 to 1.8 across different regions.
