Annual Savings vs Electricity Rate
How Solar Savings Are Calculated
Solar panels produce electricity based on system size, sunlight hours, and system efficiency (typically ~80%).
Formula
Daily Production = System kW x Sun Hours x 0.80 (efficiency)
Annual Savings = Daily Production x 365 x Electricity Rate
Break-Even = System Cost / Annual Savings
Example Calculation
6 kW system, 5 sun hours/day, $0.14/kWh, $15,000 cost after incentives.
- 01Daily production = 6 x 5 x 0.80 = 24 kWh
- 02Annual production = 24 x 365 = 8,760 kWh
- 03Annual savings = 8,760 x $0.14 = $1,226
- 04Break-even = $15,000 / $1,226 = 12.2 years
