Local roots. Long Island neighbors.
We didn't just open a business on Long Island. We grew up in Saint James, and our roots in this community run deep. That's why our neighbors trust us with the solar, roofing and heat pump decisions that matter most for their homes and businesses.
A local company that's still here.
Several of the big national solar companies have shut down in the last few years, leaving Long Island customers with no one to call. We've stayed lean, local and focused on doing right by our customers.
We design your system, handle the permits, and install with our long-time partner Greenleaf Solar. One team covers solar, roofing and heat pumps, so there's no finger-pointing between contractors.
More about Power House →About our numbers: Project counts include solar projects our founder, Steve Maroney, designed, advised on, sold and supported as a solar consultant with another Long Island solar company from 2013 to 2024, plus Power House Home Energy projects since he founded the company in 2024. Many of those homeowners are still his customers and referral partners today.
Thirty villages, one Town, and we know the difference.
The Town of North Hempstead has 30 incorporated villages, and many addresses fall inside one. Town permits take a little longer here, and each village runs its own building department. We confirm the right office and handle the paperwork either way. Homes in a designated historic district also go through that district's review, which we coordinate with the permit office for approval.
Town of North Hempstead
Unincorporated hamlets go through the Town of North Hempstead Building Department. Town permits here typically take 6–8 weeks, a bit longer than neighboring towns, so we file early.
The Villages
From the Great Neck villages to Sands Point, Munsey Park, Roslyn and Westbury, each village has its own building department. Each village sets its own process and timeline, and we confirm it for your address up front.
Villages that cross Town lines
Floral Park, New Hyde Park and Mineola are split with the Town of Hempstead, and Old Westbury, East Hills and Roslyn Harbor are split with the Town of Oyster Bay. We confirm your office before we file.
Every project, in any town, also needs PSEG Long Island interconnection approval before installation, then a final inspection and Permission to Operate (PTO) from PSEG Long Island before the system turns on. We handle all of the paperwork and coordination with PSEG Long Island. Install day itself is fast: most solar installs take one day, larger systems one to two days, and systems with battery backup two to three days. A roof replacement or a heat pump install each typically takes one day.
Every North Hempstead community we serve.
Grouped by area, because nearly every neighborhood here includes both villages and unincorporated hamlets.
Great Neck
The Great Neck peninsula, including the Villages of Great Neck, Great Neck Estates, Great Neck Plaza, Kensington, Kings Point, Lake Success, Russell Gardens, Saddle Rock and Thomaston, and the hamlets of Great Neck Gardens, Harbor Hills, Saddle Rock Estates and University Gardens. Most of the peninsula is village territory, each with its own building department.

Manhasset & the Plandomes
Manhasset and Manhasset Hills, plus the Villages of Munsey Park, Plandome, Plandome Heights, Plandome Manor, Flower Hill and North Hills. Colonials and Tudors on wooded lots, where shade analysis comes first.

New Hyde Park & Floral Park
The Villages of New Hyde Park and Floral Park, plus North New Hyde Park. Both villages are split with the Town of Hempstead, so we confirm your office first.
Tree-by-tree shade analysis
Our satellite design tools model shade on your exact roof and calculate how much each individual tree reduces your output. You see real production numbers before you commit, and you only address the trees that make a real difference.
Big homes, big loads, battery backup
Pools, central air, EV chargers and large square footage drive electric bills high. We size systems to your real usage, and a Tesla Powerwall or Enphase battery keeps the essentials running through storms and outages.
Battery backup →Solar and heat pumps
Many Nassau homes still heat with oil or gas, and fuel prices keep climbing. A heat pump replaces most of that fuel burn with electricity, and solar makes that electricity yours. PSEG Long Island offers heat pump rebates, and you can keep your oil or gas system as backup and still qualify. We size the solar and the heat pump together, so your panels are built for the load you'll actually have.
Solar + Heat Pump →Paying for it
Cash, loan, lease, or our Participate Energy program, an incentive that lowers your investment by 25–35%. New York's solar tax credit (25%, up to $5,000) can apply too. We'll walk you through every option side by side.
Payment options →Frequently asked questions
How long does it take to get a solar permit in North Hempstead?
Town of North Hempstead permits typically take 6–8 weeks, a bit longer than neighboring towns, so we file as early as possible. Homes in one of the Town's 30 incorporated villages go through that village instead, and we confirm the timeline for your address up front. The installation itself is fast: most solar installs take one day, larger systems one to two days, and systems with battery backup two to three days. A roof replacement or a heat pump install each typically takes one day. Every project also needs PSEG Long Island interconnection approval before installation, and a final inspection and Permission to Operate (PTO) before the system turns on. We handle all of the paperwork and coordination with PSEG Long Island.
Is my Great Neck home in a village?
Probably, but not always. Most of the Great Neck peninsula is divided among nine incorporated villages, each with its own building department, while Great Neck Gardens, Harbor Hills, Saddle Rock Estates and University Gardens are unincorporated. We confirm which applies to your address before we file.
My property has a lot of mature trees. Can I still go solar?
Often, yes. We use satellite design tools to model shade on your exact roof and calculate, tree by tree, how much each one reduces your system's output. That lets you decide whether any tree work is worth it.
I have a large home with a big electric bill. Can solar cover it?
Often, yes. Larger homes usually have roof space for a bigger system, and we size it to your actual usage, including pools, central air and EVs. Battery backup is a popular addition.
