You can calculate how many solar panels you need by dividing your yearly electricity usage by your area's production ratio and then dividing that number by the power output of your solar panels. System Size (kW) = (Monthly kWh × 12) / (365 × Sun Hours × (1 - Losses/100)) This formula has been verified by certified solar engineers and complies with industry standards. Precision in. . Size a PV system, estimate energy output, or find panel count from your usage, sun-hours, and performance ratio — with steps and units. The mode changes what you provide (e., daily vs monthly load, or target kW vs usage-based sizing). Draw your roof outline on the satellite map, choose your panel size, and the tool instantly fills in a grid of panels — then calculates estimated capacity, annual energy output, and CO2 savings. Accurately sizing your solar panel array is the foundation of every successful installation.
