Storm Season Is Coming: How Solar and Battery Backup Keep Maine Homes Powered

Ask anyone who has spent a winter here and they will tell you the same thing: in Maine, the power goes out. Nor’easters, ice storms, and heavy wet snow have knocked out the grid more often in recent years, and the trend is not slowing down. As we head into fall here in Bar Harbor and across Downeast Maine, it is the right time to think about how your home stays warm and lit when the lines go down.

At PV Maine, we make solar simple and stress-free, and one of the questions we hear most this time of year is whether solar keeps your power on during an outage. The honest answer surprises people, so let us clear it up.

Solar Alone Will Not Power Your Home in an Outage

Here is something a lot of Maine homeowners do not realize: a standard grid-tied solar system shuts off during a power outage. It is a safety feature, not a flaw. When the grid goes down, your panels stop sending electricity so that line crews can make repairs safely. That means even on a sunny morning after a storm, a solar-only home is just as dark as the rest of the street.

The piece that changes everything is battery storage.

How Battery Backup Works

A home battery stores the extra electricity your panels produce during the day so you can use it at night or when the grid fails. Pair solar with a battery and you get real energy independence during an outage:

•     Your lights, refrigerator, internet, and well pump keep running

•     Your heat pumps or furnace fan stay on to keep the house warm

•     Your battery recharges from the sun each day, so a multi-day outage is not a countdown to a cold house

You decide which circuits to protect. Some folks back up the whole home; others cover just the essentials to stretch their stored power further. Either way, there is no generator to fuel, no fumes, and no 2 a.m. trip outside in an ice storm.

Why This Matters More in Maine

Maine’s grid takes a beating. Weather-related outages have been rising across the state, and rural and coastal communities, including much of Downeast Maine and the islands, often wait the longest for crews to reach them. A battery turns your solar array into a quiet, automatic backup that kicks in the moment the power drops.

There is a financial upside during normal weather, too. Through Maine’s Net Energy Billing program, the extra solar you send to the grid earns credits that roll over to help offset your bill later. A battery lets you lean on your own stored power during expensive peak hours instead of pulling from the grid.

What About Incentives?

Let us be straight with you, because there is a lot of noise out there. The 30% federal residential solar tax credit expired at the end of 2025, so a homeowner buying a new system in 2026 cannot claim it. Any company telling you otherwise is not giving you the full picture.

The good news is that real Maine benefits are still in place:

•     Net Energy Billing still credits the solar power you export to the grid

•     Solar equipment is exempt from Maine property tax, so adding panels will not raise your assessment

•     Efficiency Maine loans can help finance a solar-plus-storage project

Every home and budget is different, and that is exactly the kind of thing we walk through with you honestly, with no pressure.
