How Much Do Solar Panels Cost in New Hampshire?
Looking into solar panel cost for your New Hampshire home? You’re probably wondering “how much do solar panels cost in New Hampshire?” Right now, you’re looking at about $3.03 per watt for residential solar panels. For most homeowners, a 5 kW system runs around $15,159 before any incentives kick in. The cost of solar panels varies quite a bit though – we’ve seen prices anywhere from $12,885 to $17,433 depending on your specific setup. Here’s the thing: when you factor in the federal tax credit, the cost to install solar panels drops by a solid 30%. But here’s what’s crucial – that tax credit completely disappears after December 31, 2025. So if you’ve been on the fence about solar panels prices, this year is really your last shot at these major savings.
| System Size | System Cost | System Cost (after ITC) |
|---|---|---|
| 3 kW | $9,090 | $6,363 |
| 4 kW | $12,120 | $8,484 |
| 5 kW | $15,159 | $10,611 |
| 6 kW | $18,180 | $12,726 |
| 7 kW | $21,210 | $14,847 |
| 8 kW | $24,240 | $16,968 |
| 9 kW | $27,270 | $19,089 |
| 10 kW | $30,300 | $21,210 |
Keep in mind these numbers come from real installations happening right now in 2025. The actual cost of solar panel installation for your home might be different based on your roof, which installer you choose, and what kind of residential solar panels you go with. Most folks in New Hampshire end up needing something in the 6-8 kW range to cover their electricity usage.
New Hampshire Solar Incentives and Rebates
Here’s what you can actually save on solar panels in New Hampshire:
- Federal Solar Tax Credit: This is your biggest money-saver. You get 30% back on your taxes for everything – panels, installation, permits, the works. We’re talking $4,500-$6,600 back for most homeowners. But listen, this goes away completely on January 1st, 2026. Congress actually moved up the expiration date, so 2025 is literally your last chance.
- Property Tax Break: Most towns in New Hampshire won’t hit you with extra property taxes when your home value goes up from solar (and it will go up by about $18,000-$20,000). Each town decides this on their own, so check with your local tax office.
- Net Metering: When your solar panels make more electricity than you use, you get credit for sending that extra power back to the grid. You’ll get about 75% of what you normally pay for electricity. The state locked this program in through 2040, but if you get solar now, you’re guaranteed these current rates even if they change the rules later.
- State Rebate (Unfortunately Gone): New Hampshire used to give you 20 cents per watt back, but they shut that program down permanently in 2024. No word yet on if they’ll start something new.
Bottom line: Solar installations typically take 2-4 months start to finish, so if you want that federal tax credit, you really need to get moving soon.
Are Solar Panels Worth It in New Hampshire?
Short answer? Absolutely. Here’s why solar panels in New Hampshire make so much sense: we pay some of the highest electricity rates in the country – 23.3 cents per kilowatt-hour compared to the national average of just 16.2 cents. That means every bit of electricity your residential solar panels make saves you real money. Most homeowners break even on their investment in about 8 years, which is actually pretty fast compared to the national average of 12 years.
Here’s what you can realistically expect:
- Long-term savings: Most people save $95,000 or more over 25 years
- Monthly relief: Your electric bill typically drops by $185-$225 every month
- Home value boost: Your house becomes worth about $18,000-$20,000 more
- Bill reduction: Many homeowners cut their electric bills by 40-60%, some get down to almost nothing
Between our crazy-high electric rates and the solar incentives that are still available (for now), residential solar panels are honestly one of the smartest investments you can make for your home. Just remember – when you’re weighing how much do solar panels cost against what you’ll save, the math works even better this year because of that federal tax credit deadline.
What to Know About Solar in New Hampshire
Sun and Weather Stuff: New Hampshire actually gets pretty decent sun – about 4.6 hours of good solar production per day on average. Yeah, we get snow, but here’s something cool: solar panels work better in cold weather, and snow usually just slides right off. Plus, all that white snow reflects extra sunlight back up to your panels, which can actually boost your winter production.
Permits and Paperwork: The state has made solar permitting pretty straightforward, but your town might have its own rules to follow. Most residential solar panels need the usual electrical and building permits. Connecting to the grid through Eversource, Unitil, or Liberty Utilities is typically no big deal for home systems. Just double-check if you have an HOA – they might have their own requirements.
How Long Does Solar Installation Take?
Here’s the realistic timeline for getting residential solar panels on your New Hampshire home:
- Getting quotes and design: 1-2 weeks
- Waiting for permits: 2-4 weeks (depends on your town)
- Getting your equipment: 1-3 weeks
- Actual installation: 1-3 days
- Utility hookup: 2-6 weeks after installation
- Total time: 2-4 months from signing your contract
The permit part really depends on where you live. Bigger cities like Manchester and Nashua usually get you approved in 2-3 weeks, but smaller towns can take up to 6 weeks. Some places have started fast-tracking solar permits, which is nice. Here’s the important part though – if you want that federal tax credit before it disappears, you probably want to start this process by September at the latest. Don’t wait until the last minute and miss out on thousands in savings.
How Much Can Solar Panels Save Me in New Hampshire?
Finding out how much you can save on solar in New Hampshire is not a straightforward answer. It depends on several factors, including the solar billing of your utility company, the size of a potential solar system on your roof, and your household’s energy consumption. While most solar installers will try to cover all your electricity needs, the actual savings will depend on your home’s unique conditions. To get a personal estimate of how much you could potentially save by going solar, fill out a simple form on our website, use Google’s Project Sunroof solar savings calculator, or consult with a couple of local solar installation companies for a personalized savings calculation.

Solar Financing Explained
You can pay for solar panels in a couple of ways:
- Cash
- Installer solar loans
- Personal loans
- Cash-out refinance or HELOC
- Solar Leases or Power Purchase Agreements (PPA)
First, there is a cash purchase, which in most cases provides the best price and long-term savings, but the upfront payment is not always what you can afford. If you want to own your solar panels and don’t have about $15,000 to $20,000 in the bank, you’ll have to choose solar panel financing.
You can consider a personal loan, a home equity line of credit, or a solar loan offered by the solar company. However, keep in mind that these loans come with interest and additional fees. Solar loans often are tied to dealer fees, which can increase the total cost of your solar system by 20% or more in exchange for a lower interest rate. To ensure you get the best possible deal, it is wise to compare the dealer fees and interest rates offered by different installers. This way, you can make an informed decision based on the most favorable terms available.
Some companies offer solar leases or PPAs that require zero upfront cost. But in such cases, you don’t own solar panels, and you are not eligible for any solar rebates or federal tax credits. And, because you have to pay the solar company monthly, your total solar savings will be lower. Ask for detailed savings calculations from a solar installer to decide on the best option. In most cases, you will still be paying less for electricity.

How We Classify Solar Installers: What Matters Most?
What to Look for In a Solar Company
To ensure that you partner with a great provider that can meet your needs of going solar, look for the following:
– Make sure the solar installer has industry-standard certifications, such as those from the North American Board of Certified Energy Practitioners (NABCEP), indicating that they meet the gold standard in renewable energy installations. Also, verify if they are licensed, bonded, and insured for residential solar projects in your area. If subcontractors are involved, check their credentials as well.
– Prioritize installers with a proven track record in solar installations, ideally with at least 5+ years of experience. Ask about the number of systems they’ve installed and their project portfolio. A competent installer should openly discuss the solar panels, inverters, and batteries they use if they help to take advantage of local solar incentives and rebates, as well as warranty coverage specifics.
– Your installer should be forthcoming about the installation process and answer any questions you might have, like “How many solar panels will I need? Why?”, “Can you give me a detailed cost breakdown based on my energy consumption?”, “What solar panel brands do you install? Why?”, etc. They should also be transparent about their use of subcontractors, detailing their roles and how their work will be supervised.
– A preliminary evaluation of your roof’s condition is the groundwork. The installer should advise on necessary repairs to ensure it’s ready for solar panel installation and clarify responsibilities for any potential roof damage during the process. Discuss aesthetic concerns, such as the placement of solar panels around roof vents or the possibility of relocating vents for a more visually appealing setup.
– Check the installer’s reputation through online reviews and testimonials. They should be able to connect you with past customers who are willing to share their experiences. Personal recommendations from friends or neighbors who’ve gone solar can also be invaluable.
– Solar installation costs can vary widely, so obtaining multiple quotes is advisable. Experienced installers will adjust their offers to your home’s specifics—size, energy needs, etc. For an objective cost comparison, calculate the price per watt of the proposed system, giving you a standardized basis to evaluate different quotes.
Should You Choose a Local Solar Installer or a Big National Company?
Always choose a local solar company over a big national corporation. Small local companies that operate in a distinct local area are better than multi-state and national solar companies and large corporations. It’s the small local companies who get the best reviews on our website, and it’s the national multistate companies who get very poor reviews. Why so, you may ask?
Solar is a local service business, for the most part, and it is extremely difficult to run a solar company and offer good customer service to many locations from a central office.
Local ones have a community connection, they know the incentives and regulations in the area better, and they simply care more about you than large businesses trying to get into your pocket and overprice you. While multi-state solar companies might try to convince you by financial stability and “quality of installations across different locations”, try to choose a local company that meets all your criteria.
What Does a Solar Installation Look Like?
Here’s how a solar system installation will look like once the design for your solar system is approved:
– First, a solar installer should estimate your energy needs, and analyze your annual and monthly electricity consumption, which you can find on utility bills measured in kilowatt-hours (kWh). Such calculations will help to understand potential savings, payback period, and the system size you need.
– A home energy audit is something every experienced solar company would do to understand the size and output needed.
– Next question on the list: are your house’s roof conditions good enough for installation? A solar installer should carefully inspect the roof and ensure its conditions and orientation are good to go, how and where to better place solar panels and wire the system.
– Next, they will design the system and show you how it’s going to look.
You will usually need a permit to install solar panels from your local authorities, and the solar provider should handle all the paperwork.
– The entire process might take up to 3 months depending on the state and local regulations, while the system installation is usually up to 3 days (might take longer depending on roof conditions and system complexity).
– The installation crew should always clean up and remove any debris, leaving your house in good condition.
– When the system is installed, it should be checked and approved by local municipality inspection.
– If you’re connecting your system to the grid, it has to be wired to your local utility system. You’ll apply for connection through your utility company, which will also want to inspect your system to ensure it’s following utility guidelines. Some installers may help you with this step, so always ask. Once you have all the permits, your system will be up and running, powering your home with solar.
