A note on accuracy
These numbers are estimates based on Google Solar roof data and average local electricity rates. Your actual results depend on your real energy use, roof shading, panel choice, local rates, and installer pricing — so treat this as a confident starting point, not a final quote.
Frequently asked questions
How accurate is this solar estimate?
The estimate is based on Google Solar roof data (sun exposure, usable area, and orientation) and average local electricity rates. It’s a confident starting point, but your actual results depend on your real energy use, roof shading, panel choice, local rates, and installer pricing. Treat it as a ballpark, not a final quote.
What addresses are covered?
We have solar coverage for most residential properties in the United States where Google Solar data is available. Rural or newly constructed properties may have limited or no data — if that’s the case, we’ll let you know and save your info in case coverage expands.
How many solar panels will fit on my roof?
The tool estimates how many standard panels fit based on your roof’s usable area, orientation, and shading from satellite data, then shows the resulting system size in kilowatts (kW). Larger, sunnier, less-shaded roofs fit more panels.
How are the savings calculated?
Annual savings come from your estimated system’s yearly production multiplied by your area’s average electricity rate. Lifetime savings project that out over 25 years. Net cost reflects the 30% federal solar tax credit (ITC). Consult a tax professional about your eligibility.
