How Much Do Solar Panels Cost in New Hampshire?

As of April 2024, the average solar panel system costs $3.51/W, including installation in New Hampshire. For a 5 kW installation, this comes out to about $17,532 before incentives, though prices range from $14,902 to $20,162. After the federal tax credit, the average price drops by 30%.

System SizeSystem CostSystem Cost (after ITC)
3 kW$10,519$7,363
4 kW$14,026$9,818
5 kW$17,532$12,272
6 kW$21,038$14,727
7 kW$24,545$17,181
8 kW$28,051$19,636
9 kW$31,557$22,090
10 kW$35,064$24,545

These costs are averages, and actual costs may vary. The cost of your solar panel system will depend on various factors, including the size of the system, your location, and the specific products you choose. It’s also important to remember that these costs do not include the federal ITC or New Hampshire state incentives, which could lower the price by at least a few thousand dollars.

New Hampshire Solar Incentives and Rebates

Key solar incentives and rebates available in New Hampshire:

  1. New Hampshire’s Residential Renewable Electrical Generation Rebate program: This is the state’s local solar rebate option. It provides cash-back perks of $0.20 per watt ($200 per kW) installed. You can get a total rebate of up to $1,000 or 30% of your entire system costs, whichever is lower.
  2. Property Tax Exemption: Some municipalities in New Hampshire offer property tax exemptions for the value solar equipment adds to your property.
  3. Federal Solar Investment Tax Credit: The average New Hampshire solar shopper will save $5,260 from the federal tax credit alone.
  4. Net Metering Program: New Hampshire’s net metering program can bring down the cost of solar even further.

These incentives and rebates can significantly reduce the cost of installing solar panels in New Hampshire. Most New Hampshirites pay around $24,505 to convert to solar power, which is based on the above-average local cost of solar equipment — around $3.77 per watt — and the below-average solar array size needed in the area — around 6.5 kilowatts (kW). While this total cost is about $5,500 below the national average, it’s still too expensive for many residents to justify. Thankfully, the solar perks offered by the state and local utilities help bring down the average solar conversion cost in NH by thousands of dollars, making adopting clean electricity far more accessible.

Is It Worth Going Solar in New Hampshire?

Is solar worth it in New Hampshire? While the state ranks 41st in the country for solar installations, the average electricity rate is 29.28 cents per kilowatt-hour. The average solar payback period is 8 years, and homeowners are eligible for the Residential Small Renewable Energy Rebate Program and the federal solar investment tax credit (ITC). On average, a homeowner saves $57,051 over the lifetime of their solar system. Additionally, installing solar panels can increase your home’s value by around 4.1%, adding an average of $18,335 to your home’s worth. So, for most New Hampshire residents, going solar is a worthwhile investment.


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.

Popular Myths About Solar Panels Busted 5

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.

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.
