Solar Savings Calculator
Estimate the value of solar energy you use directly in your home instead of buying that electricity from the grid.
Estimated result—
How it works
Annual saving = daily generation × self-use percentage × 365 × electricity usage rate.
Example
20 kWh/day generation with 50% self-use at $0.35/kWh is worth about $1,277.50 per year in avoided grid purchases.
Useful things to know
- This does not include feed-in tariff income for exported solar.
- Generation varies by season, shading, orientation and system performance.
- Self-consumption usually matters more when export tariffs are low.
