To calculate how many solar panels are required for your 4kW solar power system, you can divide the desired system size (4,000 watts) by the wattage of the panels. For instance, if you opt for 300-watt panels, you would need approximately 13 to 14 panels (4,000 watts ÷ 300 watts) to achieve a 4kW solar system.
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 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.
Take, for example, a 5kW solar system. The summary of all the solar panel wattages in a 5kW system should be 5000 watts (since 5kW = 5000W). Usually, we use the most common 100W, 200W, 300W, and 400W PV panels for this kind of system.
