Balcony Solar in New Hampshire
Everything you need to know about plug-in and balcony solar law in New Hampshire, plus what it means for what you're allowed to plug in, and what it saves.
Is it legal?
Yes.
New Hampshire's SB 540 was signed into law and takes effect on 1 January 2027. It permits systems up to 1,200W of plug-in solar per customer, which can be plugged into a standard outlet with no permit and no utility approval required.
The law bars utilities from charging any fee related to owning or operating a qualifying plug-in solar device.
Bright Saver's 180W and 360W kits both sit well below New Hampshire's 1,200W cap, so they need no electrician, no dedicated circuit and no permit.
What You Can Save in New Hampshire
New Hampshire's average residential electricity price is about 28.1 cents per kWh (EIA, 2026 average), one of the highest in the country. A 180 W kit generating about 270 kWh a year saves roughly $76 a year; a 360 W kit roughly $152.
New Hampshire's high electricity rates mean each kilowatt-hour the panel produces is worth more than in almost any other state. The kit pays for itself faster here than most places, with no roof work or contractor needed.
