Frequently asked questions
How long does it take to get solar turned on through PSEG Long Island?
From contract signing to Permission to Operate, expect 8-14 weeks. The biggest variable is town permitting and the PSEG LI interconnection queue, not the install itself, which is 1-2 days on the roof.
Will solar work if my roof is shaded part of the day?
Yes, with the right inverter. Microinverters (Enphase) and DC optimizers (SolarEdge) handle partial shade much better than older string inverters. We design around your specific shade pattern.
Should I re-roof before going solar?
If your asphalt roof is over 15 years old, we strongly recommend re-roofing first. Removing panels later to re-roof costs roughly $2,000-$5,000 (see Solar Panel Removal & Reinstall). We can bundle both into one project.
What is the 30% federal solar tax credit?
The Residential Clean Energy Credit (IRC Section 25D) lets homeowners claim 30% of their full installed system cost as a federal income tax credit through 2032. It applies to panels, inverters, batteries, and labor.
How does net metering work on Long Island?
Under PSEG LI's net-metering tariff, every kWh you export to the grid offsets a kWh you draw later in the month. Excess credits roll over month-to-month and true up annually.
Do you install solar with battery backup?
Yes. Pairing a Tesla Powerwall (or equivalent) gives you whole-home backup during PSEG LI outages and storm events — see our Tesla Powerwall page for details.
How long do solar panels last?
Tier-1 panels carry a 25-year production warranty (typically guaranteed at ≥85% of nameplate at year 25). Inverters carry 10-25 year warranties depending on brand. Real-world life on Long Island is 25-30+ years.
