Solar Panel Installation NH
Sentry Roofing & Solar has spent more than 25 years working on homes across New Hampshire and northern Massachusetts, and solar installation has become one of the areas we’re most proud of. When homeowners search for solar panel installation, they’re usually trying to solve two problems at once: lowering their electric bill and making sure the system is installed correctly by people who understand the roof underneath it. That’s exactly where our team comes in.
We evaluate your roof and your solar goals together, not as two separate projects. A solar panel system is only as good as the roof supporting it, so before any panels go up, we look at the age, condition, and structure of your roof to confirm it’s ready to carry a system for decades. If repairs or a replacement make sense first, we’ll tell you. If your roof is ready for solar as is, we’ll tell you that too.

- Discounts for Both Roofing and Solar

Why Homeowners Choose Sentry for Solar
Most roofing and solar companies near me searches turn up businesses that specialize in one or the other. Sentry is different. Our in-house team is trained in both roofing and solar, which means the same crew that installs your panels understands flashing, ventilation, and long-term roof health.
We also know many homeowners get multiple quotes from several companies before choosing an installer, and we welcome that comparison. A few things homeowners consistently tell us matter most:
Honest recommendations, without pressure to buy more panels than you need
Factory-trained solar installers who treat your roof with the same care as the equipment
A lifetime workmanship warranty backing our installation
170+ five-star reviews from New Hampshire and northern Massachusetts homeowners
Support that continues well after your system is turned on
What to Expect During Installation
Every solar project starts with a conversation about your electricity needs, roof condition, and sunlight exposure. From there, the entire process typically includes:
Site assessment. We inspect your roof’s structure, age, and orientation, along with shade patterns from trees or nearby buildings, and review your electric bill to understand how much electricity your household actually uses.
System design. We size your solar panel system based on your home’s energy needs and available roof space, choosing inverters and equipment suited to your property rather than defaulting to the largest system possible.
Permitting and the interconnection process. We handle the paperwork and coordination with your utility company, including the steps required to connect your system to the grid.
Installation. Our in-house crews complete the installation with the same craftsmanship standards we apply to every roofing project.
Ongoing support. Once your system is live and generating power, we remain available for questions, maintenance, and future upgrades.
Depending on system size, permitting timelines, and your utility company’s approval process, homeowners can expect the full process, from initial site assessment to final connection, to take a few months. We’ll walk you through a realistic timeline for your specific project during your consultation.
Understanding Solar Panel Installation Cost
Solar panel installation cost depends on system size, roof condition, equipment selection, and your household’s electricity needs. Cost is often discussed in terms of price per watt installed, and it varies based on the complexity of your project and the type of solar equipment you choose. There isn’t a single number that applies to every home, which is why we provide a free, itemized estimate before any work begins.
Financing Options
We offer several ways to make solar more accessible:
Solar loans, including options with no money down, so you can start saving on your electric bill without a large upfront cost
Solar leases, which allow access to solar power without owning the equipment outright
Power purchase agreements (PPAs), where you pay for the electricity your system produces, often at a lower rate than your utility company charges
Combined financing for homeowners doing roofing and solar together, which can bring your monthly payment in line with what you’re already paying in energy costs
Our solar advisors will walk you through each option, including interest, term length, and how it affects your final cost, so you can choose what fits your budget.
Solar Incentives and Tax Credits
Federal tax credits and state incentives can meaningfully reduce the cost of a solar panel system, and net metering programs allow many system owners to receive credit on their utility bill for excess electricity their panels send back to the grid.
Because tax credit percentages, eligibility rules, and state incentive programs change over time and depend on your specific situation, we recommend confirming current details with a tax professional or your utility company. We’re happy to point you toward reliable resources, including guidance from organizations like the National Renewable Energy Laboratory, as you evaluate your options.
Commercial Solar Panel Installation
Commercial solar carries its own set of considerations: larger roof spans, different structural loads, demand charges, and energy needs that scale with your business. Our team has experience evaluating commercial roofs for solar compatibility and designing systems sized appropriately for offices, warehouses, and multi-unit properties.
Commercial projects may also qualify for additional incentives, such as accelerated depreciation, though eligibility depends on current tax law and should be confirmed with your accountant. We work with business owners the same way we work with homeowners: straightforward assessments, clear pricing, and installation timelines that respect your operations.
Frequently Asked Questions
How do I know if my roof is ready for solar?
Our team inspects your roof’s age, material, and structural condition before recommending a system. If your roof needs work first, we’ll walk you through what that involves and why it matters for the long-term performance of your solar investment.
What financing options do you offer for solar?
We offer solar loans, solar leases, and power purchase agreements, along with financing that combines roofing and solar into a single plan. Our team will help you compare options based on your budget and long-term goals.
What is net metering, and does it apply in New Hampshire?
Net metering allows homeowners to receive credit on their utility bill for excess electricity their solar panel system sends back to the grid. Availability and specific terms depend on your utility company, and we can help you understand how it applies to your situation.
How long does solar panel installation take?
The full process, including site assessment, permitting, and the interconnection process with your utility company, typically takes a few months from start to finish. Installation itself is usually completed in a much shorter window.
Can I add battery storage to my solar system?
Yes. We can evaluate whether an energy storage system makes sense for your home, especially if you’re interested in backup power during outages or want more control over how you use the electricity your system generates.
Do you offer solar repairs and upgrades, not just new installations?
Yes. We service existing systems, including those originally installed by other companies, and can evaluate whether an upgrade makes sense as your electricity needs change.
Are there tax credits or incentives available for solar?
Federal tax credits and state incentive programs may apply, and they can meaningfully reduce your final cost. Because these programs and percentages change, we recommend confirming current details with a tax professional before finalizing your decision.

I wanted to have part of my roof redone before installing solar panels. I got quotes from three companies, and Sentry was more than half the cost of one of the others! They also didn’t try to pressure me into doing my entire roof. They were fast, cleaned up and it looks fantastic.
