About mysolarsavingscalc
My Solar Savings Calculator is a free solar panel calculator designed to help homeowners estimate their solar panel cost and ROI.
Welcome to My Solar Savings Calculator. Our mission is to empower homeowners across the United States, especially in Florida, with transparent, easy-to-understand data about transitioning to renewable energy. By analyzing local utility rates, state-specific incentives, and average solar production hours, we provide a clear picture of what you can expect when investing in solar panels, battery storage, and electric vehicles.
Our solar panel cost calculator by state provides accurate estimates for your specific location. We use real utility rates, state incentives, and installation costs to give you personalized solar panel cost estimates that reflect your unique situation. You can explore all our tools in the Calculator Hub.
The Federal Solar Tax Credit (Section 25D) Expired December 31, 2025
The 30% Residential Clean Energy Credit (Section 25D) applied to solar and battery storage systems placed in service through December 31, 2025. Under the One Big Beautiful Bill Act, that credit was allowed to expire — systems installed in 2026 or later do not qualify. Many online calculators and contractor quotes still incorrectly include a 30% federal credit in their estimates. Our calculators have been updated to reflect current law for 2026 and beyond, so the figures you see do not assume a federal credit. Confirm any federal incentive referenced in an installer proposal with a tax professional.
How Our Calculator Works
We use your average monthly bill to estimate your annual kWh usage. By factoring in your state's average sun hours and local electricity rates, we determine the system size needed and calculate potential long-term savings. Try our Home Page Calculator.
Data Sources
Our calculations are powered by aggregated public data, including average state utility rates from the EIA, known state-level rebates, and standard solar production metrics.
