New York solar guide
Find a verified solar installer on Long Island, NY
Long Island covers dense Nassau neighborhoods, Suffolk suburbs, and shoreline communities out to the East End. Check your roof for free first, then compare verified, licensed installers. Solar Entry does not install.
What is different about Long Island
Long Island's electric service is set up differently from most of New York. It has generally run through the Long Island Power Authority (LIPA) and its operating contractor, so interconnection and credit rules can differ from other parts of the state. Check your electric bill and ask your installer how they handle the process here.
Much of Long Island is single-family housing, which is often a good fit for a roof check. Shade from mature trees and coastal exposure vary a lot from one street to the next.
Because homes are spread across two counties, use our county pages below for a closer look at Nassau or Suffolk, and check with your town about permits and any local review.
How Solar Entry helps in Long Island
Solar Entry is a Connecticut company that also helps New York homeowners. We do not install solar. We offer a free satellite roof check, and we help homeowners choose verified, licensed installers. Infinity Solar, a New York and Connecticut installer, is one of our installer partners.
The roof check gives you a first look at sun exposure and usable roof area from your address. It is not an on-site inspection, so the installer you choose will confirm details in person and provide written quotes and warranties.
Other towns in the area
We do not have separate guides for every town. Other places in this area include Hempstead, Huntington, Islip, Brookhaven, Babylon; the roof check works for any address.

Are the rules different from the rest of New York?
Some utility rules, including how customers are credited for extra power, can differ on Long Island. Ask your installer and your utility how your system would be credited.
Does living near the shore change anything?
It can. Coastal exposure, flood-zone rules, and wind considerations may come up at some addresses. An installer and your town's building office can tell you what applies to yours.
