Estimate Solar Output
Formula
Daily Output = Panel Wattage × Number of Panels × Sun Hours × Efficiency.
Frequently Asked Questions
What are peak sun hours?
Peak sun hours represent the number of hours per day when solar irradiance averages 1000 W/m². Most locations see 3-7 peak sun hours depending on latitude and climate.
Why include system efficiency?
Real solar systems lose energy in inverters, wiring, dust, and temperature effects. A typical system efficiency of 75-85% accounts for these real-world losses.
