Will Solar Panels Work During a Long Island Power Outage?

No, standard solar panels won’t work during a Long Island power outage. For safety, PSEG LI requires that systems shut down automatically during a blackout. This prevents the problem of solar electricity feeding into the grid, which could endanger network equipment and technicians working on the lines.

What is the Solar Payback Period on Long Island in 2026?
