We didn't just open a business in Saint James. We grew up here.
Our roots in this community run deep, and that's exactly 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.
Most solar companies selling on Long Island are regional or national, and several of the big names have shut down in the last few years, leaving customers with no one to call.
When you call Power House, you reach people who live and work in Smithtown. We design your system, handle the permits with the Town or your village, 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.
Who approves your project depends on exactly where you live.
Most addresses in the Town of Smithtown go through the Town's Building Department. Homes inside the incorporated villages go through that village instead. Homes in a designated historic district also go through that district's review, which we coordinate with the permit office for approval. We handle the paperwork either way.
Town of Smithtown
Town permits move quickly, typically 3–5 weeks.
The Villages
Village of the Branch, Nissequogue and Head of the Harbor each have their own process, including an Architectural Review Board meeting. That can add a couple of weeks depending on the board's schedule.
Commack & Hauppauge
Both cross Town lines. Part of Commack is in the Town of Huntington and part of Hauppauge is in the Town of Islip, so we confirm the right permit office for your address before we start.
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 hamlet and village in the Town of Smithtown.
We've worked on homes in every one of these communities, and each one has its own mix of housing, rooflines and trees.
Saint James
Our home base. Homes here range from historic houses near the Lake Avenue business district to mid-century ranches and colonials on wooded lots, and we've worked on all of them.
Smithtown
Mostly ranches, capes and colonials built from the 1950s through the 1970s, many now due for a new roof, which makes it a good time to add solar. Mature trees are common, and we measure their impact before you commit.
Kings Park
Post-war capes and ranches with simple, open rooflines that work well for solar. Many homeowners replace an aging roof and add panels in the same project.
Nesconset
High ranches and colonials on quarter-acre lots, often with clear south- or west-facing roofs that make strong candidates for solar.
Commack
Larger split-levels and colonials where central air, pools and EVs push electric bills up, so a properly sized system makes a big difference. Homes on the Huntington side are permitted through the Town of Huntington.
Hauppauge
Mid-century neighborhoods where many homes still heat with oil, which makes solar plus a heat pump an especially strong combination. Part of Hauppauge is in the Town of Islip; we file with whichever office covers your address.
Village of the Branch
An incorporated village with its own permit process and Architectural Review Board. We prepare the ARB submission and tell you the meeting date up front.
Nissequogue
Larger lots and waterfront homes often mean room for bigger systems or ground mounts. Heavy tree cover is common, and some properties need selective tree work. Village ARB review applies.
Head of the Harbor
Wooded estate properties and historic homes, where careful design matters. Tree work is sometimes needed, and our tree-by-tree shade analysis shows which trees are worth addressing. Village ARB review applies.
Lots of trees? We measure every one.
Mature trees are part of what makes Smithtown beautiful, and they're the most common question we get here. Tree work is sometimes needed, more often in Nissequogue and Head of the Harbor, but usually far less than homeowners expect.
Tree-by-tree shade analysis
Our satellite design tools model shade on your exact roof and calculate how much each individual tree reduces your system's output. You see real production numbers before you commit, and you only address the trees that make a real difference.
Solar and heat pumps in Smithtown
Many Smithtown homes still heat with oil, and oil prices have climbed sharply. A heat pump replaces most of that oil 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
Is there a solar company based in Smithtown?
Yes. Power House Home Energy is based in Saint James, in the Town of Smithtown. We're lifelong Saint James residents. Our founder, Steve Maroney, has helped more than 100 Town of Smithtown homeowners go solar since 2013, and we serve the rest of Long Island too.
How long does it take to get a solar permit in Smithtown?
Town of Smithtown permits typically take 3–5 weeks. In the incorporated villages, Architectural Review Board (ARB) review can add a couple of weeks depending on the board's meeting schedule. 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.
Do I need village approval for solar in Nissequogue, Head of the Harbor or Village of the Branch?
Yes. Homes inside those three villages go through the village rather than the Town of Smithtown, including a review by the village's Architectural Review Board. That can add a couple of weeks depending on the board's schedule. We prepare and file everything and tell you the timeline up front.
My property has a lot of 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. Some properties, especially in Nissequogue and Head of the Harbor, need selective trimming or removal; many don't. On larger lots, a ground mount may be an option.
