Solar panel “size” refers to two key measurements: Physical Size: 51-102 cm long, 41-66 cm wide (typical range). These dimensions work together with power output to determine your system’s efficiency, cost, and performance.
To estimate the number of panels: Panel Count = System Size (W) ÷ Panel Wattage Panel choice (300W vs. 500W) will affect required roof space and configuration. How Do You Choose the Right Inverter and Charge Controller? Correct sizing ensures system safety and performance across all solar panel designs. How Do You Estimate the Correct Battery Size?
Use this core formula to calculate solar system size: System Size (kW) = Daily Energy Use ÷ Peak Sun Hours × 1.2 The multiplier (1.2) accounts for system losses from wiring, shading, and inverter inefficiencies. Example: 30 kWh/day ÷ 5 peak hours × 1.2 = 7.2 kW system How Many Solar Panels Do You Need for Your System Design?
Note: It’s important to note that the system efficiency factor used in the solar panel sizing calculation accounts for various losses in the overall system, not just the efficiency of the solar panels. A typical system efficiency factor of 0.8 (80%) is often used to account for these cumulative losses.
