Why Long Island Homeowners Choose SolarOPower
Long Island electricity rates have risen nearly 30% over the past five years, and PSEG Long Island's average residential rate of $0.22 per kWh is among the highest in the continental United States. For a typical Long Island homeowner using 900-1,100 kWh per month, that translates to monthly bills of $200-$280 — and they keep climbing every year.
A residential solar panel installation from SolarOPower lets you lock in predictable energy costs for the next 25+ years. Instead of renting electricity from PSEG every month, you generate your own power from the Long Island sun — and the savings add up fast. Most of our customers eliminate their electric bill entirely during sunny months and pay only the $19.50 monthly PSEG connection fee.
We are not a national solar company that ships in installers from out of state. Our crews live on Long Island, our project managers know every township's permitting requirements from Hempstead to Southampton, and we are available for in-person service calls whenever you need us.

Residential Solar Installation Process
We have refined our installation process over 1,200+ Long Island installations. Here is what to expect from day one to system activation:
Free Roof Assessment & Energy Audit (Day 1-7)
Our solar consultant visits your home, inspects your roof orientation and shading, reviews 12 months of PSEG Long Island bills, and discusses your energy goals. You receive a written proposal with system size, cost, savings estimate, and payback period — typically within 3-5 business days.
System Design & Permitting (Week 2-5)
Our engineers design your custom solar system using Aurora Solar software. We then file all required permits with your township (Hempstead, Oyster Bay, Brookhaven, Smithtown, Islip, Southampton, etc.) and submit the PSEG Long Island interconnection application.
Solar Panel Installation (1-2 Days)
On installation day, our NABCEP-certified crew arrives at 7:30 AM. Most residential solar installations are completed in 1-2 days. We install the racking, panels, inverter, and wiring — then clean up the site so you would never know we were there (except for the new panels on your roof).
Inspection & PSEG Interconnection (Week 6-10)
Your township conducts a final building/electrical inspection (typically within 2 weeks of installation). Once approved, PSEG Long Island installs your bidirectional meter and authorizes system activation. Total timeline from contract to powered-on system: 8-12 weeks.

Frequently Asked Questions
A: The average 8 kW residential solar system in Long Island costs $24,000-$28,000 before incentives, or $15,000-$19,000 after the 30% federal tax credit and NYSERDA rebates. Most Long Island homeowners see payback in 7-10 years and $42,000-$52,000 in total 25-year savings.
A: From signed contract to powered-on system, the typical timeline is 8-12 weeks. Design and permitting take 3-5 weeks, installation is 1-2 days, and PSEG Long Island inspection and interconnection take 3-5 weeks.
A: Grid-tied solar systems shut off automatically during outages for safety compliance. To keep your lights on during Long Island power outages, pair your solar system with a Tesla Powerwall battery – see our Battery Storage page for details.
A: If your roof is more than 12-15 years old, we recommend replacement first. We partner with licensed Long Island roofing contractors and can bundle roof replacement with your solar installation, often financing both together.
A: When your solar panels produce more electricity than your home uses, the excess flows back to PSEG Long Island’s grid and you earn credits on your bill. At night or on cloudy days, you draw power from the grid using those credits. Most Long Island solar customers see their annual electric bill drop to just the $19.50 monthly connection fee.
