Maine solar, sized from your electric bill

Electric heat, heat pumps, and oil or gas homes with electric “shoulders” can live on the same block and still need different arrays. Coastal wind and inland cold both push winter kWh up; for a lot of meters, summer cooling is the quieter stretch. Paste a recent bill (or enter kWh). You get a size ballpark and cash / loan / lease shapes — not a Vacationland average-home chart.

Central Maine Power covers much of southern and central Maine, including a large share of greater Portland. Versant Power serves northern and eastern corridors, including Bangor territory. Co-ops and other arrangements show up in pockets. Export credits and interconnection follow the utility on your bill and can change — we won’t invent a statewide Maine credit chart. Your installer confirms the account.

There is no honest statewide price for Maine rooftop solar. Cost follows system size, and size follows the kilowatt-hours on your bill — not a “typical Maine home” chart. Helio shows a ballpark and cash / loan / lease shapes from your usage; an installer bid comes after the roof and the meter.

Maine outages are often a winter story. Grid-tied rooftop solar shuts off when the grid drops — extra modules won’t run the heat through an ice storm. Tree shade and snow shedding belong in the site survey. Size from usage first; treat storage as its own decision.

If ice or nor’easter outages are why you’re looking, skim /batteries after you size from the bill — panels alone aren’t backup. Battery basics.

Helio is the homework. You leave with a system size, a production sketch, and a cost range so a sales visit is not the first time you have seen the numbers. That is a ballpark.

An installer quote is after a site survey: roof, electrical panel, setbacks, utility paperwork, and the equipment they will actually hang. Those details can raise or lower the number. That is the bid.
