Understanding Solar System Sizing

To completely offset your electricity bill, a solar array must generate enough daily energy to match your consumption. However, solar panels don’t produce power 24/7; they only generate significant energy during Peak Sun Hours.

System Efficiency: Real-world solar systems lose energy due to heat, wiring resistance, shading, and inverter conversions. A standard Performance Ratio (Efficiency) is 80%. If you need 10kWh a day, your panels actually need to be rated to produce ~12.5kWh to account for these unavoidable physical losses.
