Solar Panel Area Calculator

Estimate the roof or ground area needed for a solar panel system based on annual electricity use, local solar production, panel wattage, and panel efficiency. The calculator determines the system size required and converts it into total panel area with a practical spacing factor.

Solar Panel Capacity Calculator

Estimate the recommended solar panel system capacity in kilowatts based on monthly electricity usage, average peak sun hours, system efficiency, and a safety buffer for future demand and losses.

Solar Panel Calculator

Estimate the recommended solar panel system size based on monthly electricity usage, sunlight hours, roof efficiency, electricity offset goal, and panel wattage.
