Frequently asked questions
How are solar savings calculated?
The estimator uses your monthly electricity bill, local sun hours, system size, and current energy rates to project savings over 25 years, accounting for panel degradation and electricity rate increases.
Does this include tax credits?
Yes — the calculator factors in the federal solar Investment Tax Credit (ITC) and allows you to add state or local incentives.
How accurate is the payback period estimate?
The estimate provides a reasonable ballpark based on national averages. Actual savings depend on your roof orientation, shading, local utility rates, and installation costs.
