Calculate the size of solar panels

What is a solar panel size estimate calculator?

The Solar Panel Size Estimator Calculator is your go-to resource when planning a solar installation. It is crucial when you’re assessing the feasibility of solar energy for your home or business.

How do you calculate solar system 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?

How do I choose the right solar panel size?

The solar panel size directly affects how much power your system can produce, how many panels you need, and whether your available roof space can support the installation. Choosing the proper system is not only about the solar panel dimensions. You should also consider wattage, number of cells, layout possibilities, and energy consumption.
