Maine OK’d solar panels for balconies. Safety guidelines haven’t caught up.

MAINE MORNING STAR • October 2, 2026

Over the past year and a half, a dozen states, including Maine, have embraced a new vision for solar power: small, cheap panels that can be hung from a balcony or porch, be plugged into a standard wall outlet and take a dent out of residents’ utility bills. These systems, known as balcony solar or plug-in solar, are attractive because they can be installed without permits, contractors or large investments. They can allow renters to tap into clean electricity.  Lawmakers say the systems can help at a time when residents’ power bills are skyrocketing and utilities are struggling to keep pace with demand. But for most Americans the systems still sit in a legal gray area. That’s because the “plug and play” simplicity that creates balcony solar’s appeal might not yet work safely with most household electrical systems, experts and utilities say.
