One local team, start to finish
From First Call to Powered On — We Handle It All
We design, permit, and install your system, then run the PSEG Long Island interconnection and inspection through permission to operate. One Long Island team from your first roof review to the day your panels switch on.
Straight answers, not a sales script
An honest look at your roof, your bill, and whether solar makes sense — before you commit to anything.
Roof, shade, usage & bill review
Per-plane orientation, pitch, decking age, and 12 months of PSEG usage decide your real system size.
In-house system & battery design
We size your system, model battery backup, and apply the NY 25% credit and NYSERDA rules to your home.
Permitting & PSEG interconnection
We handle town and village permits and the PSEG Long Island interconnection paperwork end to end.
Our licensed install crews
Our licensed crews handle the install — roof, electrical, and commissioning — usually in 1–2 days.
Support through permission to operate
We stay on it through inspection and PSEG approval, so you're not chasing anyone to get switched on.
What we check first
Not every roof should go solar — and that's the point.
We start with your last 12 months of PSEG usage and your actual roof. If the math doesn't work, we'll tell you to wait. When it does, our crews handle the install.
Roof and shade review
Per-plane orientation, pitch, decking age, and shade modeling — before any panel layout is drawn.
PSEG bill analysis
12 months of actual usage and rate plan from your PSEG Long Island account, not a national average.
Battery backup planning
Critical-loads vs. whole-home, NYSERDA solar + storage eligibility, and LIPA Dynamic Load Management.
Incentive eligibility review
NY State 25% solar credit, NYSERDA programs, and a verified read on any active federal program.
Honest quote comparison
Already have a quote from another company? We'll review it line by line and show you how our proposal compares.
No-pressure next step
Calculator and written assessment first, a call only when you're ready. We'll say straight if your home isn't a fit right now.
How we work
A consultative path, not a sales pipeline
Three structured steps, designed around your home — not around a monthly sales quota.
Analyze your bill and roof
We pull your last 12 months of PSEG Long Island usage, model your roof's orientation and shade, and tell you up front whether solar even makes sense for your home.
Design your solar/battery path
We size a system around your actual usage, evaluate battery options for backup or time-of-use savings, and flag any roof-readiness work before panels go up.
Compare incentives, financing, and next steps
We model the New York 25% solar credit, PSEG net metering, NYSERDA storage incentives, and any active federal program — across cash, loan, and lease side by side.
How we model your solar savings
Inputs you can verify, not promises you can't
Every number on your written assessment ties back to one of these inputs. No magic, no inflated savings claim.
Bill + roof inputs
12 months of PSEG usage, rate plan, roof orientation and pitch, and shade modeling per roof plane.
System size range
Sized to match annual usage, with buffer for batteries or EVs. Range, not a single number.
New York 25% solar credit
25% of qualified equipment expenditures, capped at $5,000, with up to a five-year carryforward.
PSEG energy credits
Net metering and Time-of-Day Energy Credit Bank impact on your monthly PSEG Long Island bill.
Battery + NYSERDA storage
Critical-loads vs. whole-home backup, NYSERDA Long Island solar + storage incentive, LIPA Dynamic Load Management.
Financing + payback
Cash, loan, lease, and PPA modeled side by side — with the federal incentive context that actually applies in 2026.

Six reads on your home, not a sales pitch
Every Long Island Solar Installation Pros assessment is a written document. Here is what it covers — built from your roof, your bill, and any quote you're already weighing.
Utility bill + proposal review
12 months of PSEG Long Island (or Freeport Electric) usage walked through line by line, plus any competing quote you'd like a straight second read on.
Roof-readiness review
Decking, shingles, structural load, shade modeling per roof plane, and how a panel layout would have to work around hips and dormers on your specific home.
Battery backup planning
Critical-loads vs. whole-home framing, NYSERDA Long Island solar + storage incentive eligibility, and LIPA Dynamic Load Management context. Battery backup is a planning option, not a guarantee of uninterrupted power.
Incentive + financing read
New York State 25% solar credit math, PSEG net metering and Time-of-Day context, and a verified read on any active federal program — not an assumed credit on a 2026 install.
Town & permitting context

EV + electrification planning
Sizing solar to cover home driving energy and pre-wiring for a Level 2 charger when it makes sense — our licensed electricians confirm panel capacity and code.
