Clearwater Solar
Thrilled to have it going! Got our PTO and they came out to turn it on same day. We had solar at our old house and liked it so we knew adding panels down in Florida would save us even more money. Christian is an amazing sales representative, if you get the chance to work with him you’re in good hands! Also great to support a local Clearwater company any chance we can.

Bad company
don't use this company they play world game on the contract . salse people lied and they use the world on contract explained different meaning . not like what they said to you will have no bill or negative bills . because they never tell you when you change to 1:1solar buy back energy company every months have TDU deliver fee that's meaning you have to reduce more power than what you really use then can cover your bills. and they told me i have to use the solar panels one years see can reduce the energy on contract or not if not they will add more panels after one year i called they tell me they can't put because of contract they use word syetem will offset last 12 months of usage . start one year before i sign the contract . but my house is new i not have one year before energy bills. if anyone looking for solar company try open your eyes. my bills not lower higher than before.

Excellent Customer Service
Sunergy’s estimate came in slightly higher than some other companies but their professional install (Thank you Mark, Brian and Manny) and EXCELLENT (Devyn Cote)customer service made the extra cost well worth it- Delays in install were completely beyond anyone’s’ control (poor weather) and the team kept me informed throughout the process.

Go with Dublin Ohio Gold Path Solar
Unlike any other solar company. I cannot recommend Gold Path Solar enough! -Thorough and prompt communication with a single point of contact - you have a rep who will answer your questions -Knowledgeable staff makes the whole process easy -Friendly and professional customer service -Dublin, OH based (support local business!) -American made panels We have always been skeptical of door-to-door solar salespeople, but when Gunner with Gold Path Solar came to our door back in March, we were pleasantly surprised by his politeness and courtesy. He noted that we had a no soliciting sign, and asked if he could just leave us some information about the product. We agreed and he was on his way. After looking into the information Gunner provided we were connected with Adam, who we now know is a co-founder of the company and were again pleasantly surprised by his professionalism, knowledge, and courtesy. After a meeting with Adam where he discussed the American-made solar panels Gold Path uses, the company's commitment to building long-term customer relationships, and the potential cost savings on our electric bill, we struggled to see a downside, so we set up our site survey. Matt conducted the survey a few weeks after our initial consultation with Adam and he was just as amazing as we had come to expect from Gold Path's employees. We had our 17 panels installed yesterday by a team of 2 guys - Justin and Wilmer. It only took a few hours and we barely knew they were here. They were great with our dogs and thoroughly cleaned up after the install (they even borrowed my vacuum at one point when they were done with our attic access). If you're in Ohio and are considering solar panels, please reach out to this Dublin, Ohio based company!

Best solar companies for home battery installations in New Hampshire
Batteries have become increasingly popular because they take an intermittent energy source like solar and turn it into a reliable and consistent supply of electricity. We recommend getting a solar battery quote if you want a backup power source or if your utility company doesn’t have a net metering program that buys excess solar energy at the full price of power, as you could save a little extra on your electric bill.
The biggest benefit of energy storage for New Hampshire residents is the access to backup power when the grid is down. While a battery can slightly increase energy bill savings, they are generally minimal.
Here are some New Hampshire companies that install panels and solar battery storage systems:

How to find the best solar panel company near you
Picking a solar company is the most important decision you make when going solar. You need to trust them to drill holes in your roof, help you navigate financing and incentives and provide you with 25+ years of customer service.
Check out this video where our founder, who also founded a successful solar installation company, explains what to look for when choosing the best solar company near you.
Top things to consider when choosing a solar company in New Hampshire:
Years in business
One of the first things to look at when finding a company is how long they have been in business. We suggest looking for companies that have been around for at least five years, as the longer it has been in business, the more likely it is you’ll have a positive installation experience.
Companies with five or more years of experience will probably have established after-sales service and warranty support. It signals that they aren’t a company in it to make a quick buck; they’re in it for the long haul.
Of course, there are exceptions to this rule, which is why you should also keep a few other factors in mind.
Licenses, insurance and certifications
Solar companies that are licensed, insured and hold certifications take their business seriously. Look for companies that have NABCEP Certified professionals or certified electricians on staff and are properly insured, so their workers, and you, are protected.
New Hampshire requires a master electrician's license or work as a journeyman alongside a master electrician to install solar panels. Becoming a master electrician requires at least one year of experience in the state, mandatory experience hours, and passing a licensing exam.
Financing options
Not everyone has thousands of dollars to spend on a solar panel installation. So, you’ll want to find a company with solar financing options that work for you. Ask for quotes for various types of financing plans to see which one will work best for your budget. Solar loans are often your next best choice if you can’t pay in cash. But, if you don’t pay federal income taxes or can’t qualify for a loan, finding a company that offers solar leases or power purchase agreements might be the right move.
Services and products offered
Don’t choose a company that can’t complete the job that you want to be done. If you need an energy storage system, get quotes from companies that install batteries! Maybe you want a particular brand of panels or an electric vehicle charger installation. Ask the company if they provide those services or carry those brands so you don’t have to settle for less.
Customer review scores
Customer ratings give valuable insight into how a solar company actually operates and treats its customers. Read SolarReviews, Google and Yelp reviews to understand the company’s installation process, sales practices and overall customer service. But remember that some companies incentivize customers to leave positive reviews, so make sure you read reviews with some scrutiny.
Warranty
Any reputable solar installation company will offer a workmanship or labor warranty that covers any damages that may occur during the installation process. We recommend using an installer with at least a ten-year labor warranty.
Some installation companies, like SunPower, include a system performance guarantee. This promises you’ll get a certain amount of electricity from your solar panels and is an excellent added protection.
New Hampshire incentives and rebates
Solar incentives and rebates can cut the cost of installing solar in New Hampshire by thousands of dollars. The most significant incentive is the 30% federal solar tax credit, available to any taxpayer in the country when they purchase solar panels or battery storage.
Some states and utility companies offer additional solar incentives, saving homeowners even more money. Here are the solar incentives available in New Hampshire:
Incentive | Eligibility | Type |
---|---|---|
Residential Clean Energy Tax Credit | Federal | Personal Tax Credit |
Local Option - Property Tax Exemption for Renewable Energy | State | Property Tax Incentive |
Net Metering | State | Net Metering |
How much can you save with solar incentives?
What to look for in solar quotes in New Hampshire
Once you’ve found a few companies you like, you can start getting solar quotes. You can get a better deal when you get quotes from multiple solar installers; we suggest getting at least three quotes. Here are a few of my favorite tips and tricks for comparing quotes and what questions you should ask installers.
System size and energy production
All solar quotes should include the size of the system and how much energy it is projected to produce. Most of the quotes you get will probably be in the same ballpark. But, if one is drastically larger or smaller than the others — ask about it! Maybe one installer included shading from a tree, while another based its estimates on having that tree removed.
New Hampshire experiences an average of 195 sunny days. The Granite State also sees 4 to 4.5 peak sun hours each day, which is pretty average for most U.S. states. That's enough sunlight for solar panels to cover most, if not all, of your electricity costs. Your local solar installer will tell you exactly how many solar panels you need to fit New Hampshire's climate and help cut down on your bills.
If you choose reliable installers, you can trust that these estimates will be as accurate as possible. But you can always double-check using the SolarReviews solar calculator and enter the information received in your quotes.
Pricing
You should know as much as possible about how much the solar panels cost. Make sure you know both the total cost of the system and the price per watt of solar installed. The cost per watt makes it easier to compare prices between quotes and gives you a better idea of how fairly the system is priced. The average price of solar is about $2.26 to $3.4 per watt in New Hampshire, so anything in that range is a fair price.
Financing
Financing is one of the most important things to look for in your solar quote. There are a few different things to keep an eye out for, depending on what type of solar financing you’re using.
If you’re looking to use a solar loan, you should ask the company for both a cash quote and the financed quote. Solar loans include something called dealer fees, which can sometimes add 20% or more to the total cost of your system in exchange for a lower interest rate. It’s worth comparing what dealer fees and interest rates you’re quoted from different companies to get the best deal possible.
If you want a solar lease or power purchase agreement (PPA), you’ll want to look for an escalator clause in the contract. The escalator clause outlines how much your payments will go up every year. Ideally, this should be lower than the rate at which electric prices increase in your area, typically about 3% annually. If the escalator rate is higher than this, you could end up paying more than if you hadn’t gone solar at all!
Payback period
Some quotes may include when you’ll break even, meaning when your panels have saved as much as you spent on them. If it’s not explicitly listed on the quote, you can compare any savings estimates they provide to the system’s total price and get a rough estimate of when your panels will pay themselves off. The shorter the payback period, the better.
Equipment
Good quality solar installers will carry good quality equipment. So if you pick an installer you trust, you can expect reliable products. But, it can’t hurt to research and ask the installer questions about what would be going on your roof.
Most solar panels installed today are about 400 watts in size and have efficiency ratings above 19%. Higher wattage and efficiency panels can produce slightly more electricity but may add a price premium. You’ll want to make sure the solar panels have the industry standard 25-year product and performance warranties.
