How many solar panels do I need? Use our 2025 calculator to size your system by home size, kWh usage, and location. Get panel count, roof space, and kW—free from SolarTech.
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.
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.
For a monthly energy usage of 1,000 kWh, you would need at least 17 solar panels and three solar batteries to go off-grid. Assumes 400-watt solar panels and 13.5 kWh lithium-ion batteries. Can solar panels run an entire house?
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.
