To determine how many panels for 10kW system installation you need, you’ll need to know the wattage of each panel.

Most modern solar panels range from 370W to 450W. The formula is simple:

Total System Size (in Watts) ÷ Panel Wattage = Number of Panels

  • For 370W panels: 10,000 ÷ 370 = around 27 panels

  • For 400W panels: 10,000 ÷ 400 = 25 panels

  • For 450W panels: 10,000 ÷ 450 = around 22 panels

So, how many panels for 10kW system setups do most people need? The answer is usually between 22 and 28 panels, depending on the exact panel wattage used.

The higher the wattage per panel, the fewer panels are needed. The lower the wattage, the more panels required.

Factors That Influence the Total Panel Count

The number of panels for your system doesn’t just depend on panel wattage. Several other factors can affect how many panels for 10kW system installs are required:

  • Panel Wattage: Higher wattage = fewer panels

  • Panel Efficiency: Premium panels convert more sunlight into power

  • Roof Orientation: North-facing roofs get the most sun in Australia
