Palmetto Reviews

Palmetto Solar has been nothing but solid for me. Their app is clean, easy to use, and honestly kind of addictive — I catch myself checking my energy production like it’s a scoreboard. And the savings on my electric bill are the real deal. Every month I’m seeing the difference.

Their customer service deserves a shoutout too. Every time I reached out, they were friendly, patient, and actually helpful. No runaround, no “we’ll get back to you someday” energy — just people who know their stuff and take care of you.

If you’re thinking about going solar, Palmetto makes the whole thing smooth, simple, and worth it.

I resisted going solar for years because of the cost of installation that many quoted when they came to my door. Someone finally came to my door from Palmetto and offered a solar plan that didn’t cost me a penny to install the solar at all. They looked at my power bill and told me how many panels they would install and that they would only bill me $83 dollars a month. My wife and I did that math, and we said okay. After everything was installed and up and running, they sent me an email that said my monthly bill would only be $63 a month instead of the $83. I said, “Great”. Through the entire process they notified me of everything that happened from them getting permits from the city, to installers coming out, etc. So far I’m very pleased with their service and the money I’m saving.

Palmetto Solar is a fantastic solar company to work with! They provide great communication every step of the way. Customer service is excellent! Keeping their customers fully informed of just how simple the solar install, and payment setup is; plus keeping my expectations of the process very simple. They are available to speak to, which makes it easy to understand how things work once all is completed. I highly recommend Palmetto Solar.

Key Takeaways

Nashua Electricity Prices

If you live in Nashua, you’ve likely noticed your electric bill trending higher over the past few years. Here’s what the numbers show.

New Hampshire’s electricity rates climbed from 19.9 cents per kWh in 2021 to 23.3 cents in 2024—about a 17% rise. That’s well above the 2024 national average of 16.5 cents per kWh.

Because Nashua homeowners pay more than most of the country, solar can be a practical way to offset those higher rates. Panels generate power on-site, reducing how much electricity you buy from the grid. Learn more in our guide on home solar panels.

Over time, that steady on-site generation can help protect your budget from future rate swings. While utility prices shift year to year, sunlight is free—giving Nashua homeowners more predictable energy costs for decades to come.

Nashua Area Utility Providers

In Nashua, New Hampshire, most homes get their power from Eversource, the area’s main utility. In 2023, Eversource charged about 28.9¢ per kWh—well above the 16.0¢ national average and slightly higher than New Hampshire’s 28.20¢ average.

Why so high? New England relies heavily on natural gas for electricity, and limited pipeline capacity drives prices up during peak demand. Nashua also faces higher delivery and transmission costs, which push local rates above much of the country.

When utility rates stay this far above the national average, home solar becomes worth understanding. Producing your own power can reduce how much electricity you buy from Eversource, giving Nashua homeowners more predictable energy costs over time.

New Hampshire Solar Incentives

Nashua homeowners can tap state and local programs to lower solar costs. Explore the available solar incentives in New Hampshire below.

One key program is the Eversource ConnectedSolutions battery storage rebate, funded through the New Hampshire Clean Energy Fund. It rewards you for sharing stored energy during summer demand events.

The federal tax credit has ended, but state and local incentives remain. Leasing through LightReach also simplifies things, since Palmetto handles the commercial ITC.

Incentive Type Description Source
Eversource ConnectedSolutions Battery Storage Rebate (NHCEF) Rebate Eversource NH customers in Nashua can receive an upfront rebate of $230 per kWh of enrolled battery capacity (up to $3,000 for residential accounts) through the New Hampshire Clean Energy Fund ConnectedSolutions program, in exchange for participating in summer demand response events. Learn More

The Eversource New Hampshire Clean Energy Fund (NHCEF) ConnectedSolutions Battery Storage Program offers residential customers in Nashua an upfront rebate of $230 per kWh of battery capacity enrolled in the program, capped at $3,000 per residential account. Commercial customers can receive $250 per kWh, capped at $10,000. For example, a 10 kWh residential battery system would earn a $2,300 rebate. The rebate is paid by check once your battery receives permission to operate from Eversource’s interconnection group and is accepted into the demand response program.

To qualify, your battery storage system must have been purchased after October 1, 2022, and you must agree to participate in demand response events for a minimum of three years. During demand response events — which occur between June 1 and September 30, from 3:00 PM to 8:00 PM — Eversource may draw on your battery’s stored energy to help manage grid demand. You can expect approximately 40 events per summer, each lasting no longer than three hours. Eligible battery models include Sonnen eco (Gen 2+), ecoLinx, sonnenCore, sonnenCore+, Enphase IQ Batteries, FranklinWH aPower, and other approved models.

This program is available to Eversource NH customers only and has limited funding — as of late 2024, remaining funds were approximately $750,000, so availability may be restricted. Homeowners in Nashua are strongly encouraged to contact Eversource directly to confirm current funding availability before purchasing a battery system. Note that battery storage systems enrolled in this program may also qualify for the RSA 72:62 property tax exemption in participating municipalities.

Leasing Solar Panels

In Nashua, most homes are served by Eversource Energy, which means you can take advantage of a solar Power Purchase Agreement (PPA) through Palmetto’s LightReach program. A PPA is a simple way to go solar without buying the system yourself.

With a PPA, you don’t pay for panels upfront. Instead, you pay a set price per kilowatt-hour for the power your system produces. Because panels generate more electricity in summer than winter, your solar bill rises and falls with the seasons—but over a full year, your savings work out much like a fixed monthly lease.

Compared to paying cash, a PPA means no large investment and no maintenance to manage. Palmetto owns and cares for the system, so you can simply enjoy the power.

Go solar without the investment

With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

If you produce more than you use in a billing period, you earn a monetary credit. Extra credits roll over year to year, and you can request a payout after the March billing cycle if your balance exceeds $100.

Do solar panels increase your home value in Nashua, NH?

Yes, but it depends on how you get your panels. When you own or purchase a solar system, it can raise your Nashua home’s value. In fact, a Zillow study found homes with solar sell for about 4.1% more.

How much does it cost to go solar in Nashua, NH?

In Nashua, you can go solar with no upfront cost through a LightReach lease. For a medium-sized home, that’s a low fixed payment around $138 per month.
