Solar Savings Calculator
Check rough solar ROI before speaking to an installer.
Solar Savings Estimator
Check annual generation, payback and long-term benefit.
Input Details
Fill what you know. If a value is unknown, keep the practical default and verify the nameplate later.
How to use this result
Annual units = system size × sun hours × 365 × performance ratio. Payback = net investment ÷ annual saving.
This is a preliminary planning estimate. For certified audits, use site measurement and nameplate readings.
FAQ
Is this final solar quotation?
No. It is a screening estimate. Final output depends on roof, shadow, inverter and net-metering.
Should I add battery?
Battery adds backup but increases payback time. Grid-tied solar is usually better for bill reduction.
Solar planning tip
Do not judge solar only by capacity. Shade, roof direction, net metering and daytime usage affect real savings.
Accuracy note
The result is a planning estimate. Use nameplate wattage, measured runtime and current tariff for professional-level accuracy.
