Why Andover homeowners are going solar.
Andover is one of the most affluent communities in the Merrimack Valley, with large single-family homes, strong schools, and a residential character that supports premium solar installations with battery storage.
Andover homeowners on National Grid benefit from high retail electricity rates and the larger roof areas that come with the town's spacious colonial and contemporary homes. Many Andover installations are in the 10 to 15 kW range, often paired with battery storage for whole-home backup during outages. The town's engagement with sustainability through programs like Sustainable Andover and the Green Communities designation reflects a community that values long-term clean energy investment. Our design team handles Andover's permitting and inspection processes efficiently, and we're familiar with the architectural review requirements that sometimes apply in the historic districts near Andover Center.
What installing solar in Andover actually involves.
What Andover roofs are actually like
Andover reads suburban rather than urban. Roughly 68 percent of homes are single-family detached, about 80 percent of occupied units are owner-occupied, and the median year of construction is 1974, which means a lot of mid-century and later roofs with straightforward framing and generous unbroken plane area. Minimum lot sizes run from 15,000 square feet in Single Residence A up to a full acre in Single Residence C, so ground mount is genuinely available here in a way it is not in the mill cities downriver. The counterweight is trees. Andover holds roughly 5,900 acres of forest across a 31 square mile town, and mature canopy over mid-century subdivisions is the single most common reason a promising Andover roof underperforms on a production model.
Permitting in Andover
The Building Division at 36 Bartlet Street runs permits through an OpenGov portal, and the town publishes a solar requirements sheet with one sequencing rule that catches people out: the building permit will not be issued until the electrical permit has issued, so the electrical filing goes first. A rough electrical inspection is required before any panels are set, and a final structural affidavit has to be submitted before the final building inspection. Andover has two local historic districts under the state Historic Districts Act, Ballardvale and Central Street, but the Central Street bylaw expressly lists roof-mounted solar panels among the items outside the commission's review. Separately, if your house appears on the Andover Historic Building Survey or the state inventory, the Preservation Commission reviews the building permit.
Your utility in Andover
National Grid is the electric utility. The town also runs Andover Community Power, an opt-out aggregation launched in June 2024 under a supply contract running through the December 2027 meter reads, whose default product carries more Class I renewable content than the state minimum. One local detail shapes sizing more than most: about 21 percent of Andover homes still heat with fuel oil, well above the statewide pattern. If a heat pump conversion is anywhere in your plans, the array should be sized against the load you will have after electrifying rather than the load on today's bill.
Local programs worth knowing about
Rebates, rates and caps change over time. Confirm current terms with the provider before relying on a figure.
Andover Community Power
The town's opt-out electricity aggregation, approved by the Department of Public Utilities in January 2024 and live since June 2024. Three products are offered and the default adds renewable content above the state requirement.
Massachusetts Green Communities Designation
Andover is a designated Green Community and has used the program to cut municipal energy use. The town adopted the Stretch Energy Code effective January 1, 2011, and voted at the April 2025 Town Meeting to adopt the Specialized Code effective July 1, 2026, which applies to new construction.

Solar incentives for Andover residents.
Andover residents have access to Massachusetts' exceptional solar incentive programs, making solar one of the best home investments available:
- SMART Program: monthly payments based on your system's energy production
- Net Metering: credits for excess electricity sent back to the grid
- 15% Massachusetts State Tax Credit (up to $1,000)
- Property Tax Exemption: solar doesn't increase your property taxes
- Sales Tax Exemption: no sales tax on solar equipment

Solar in Andover, answered.
- Do you install solar panels in Andover, MA?
- Yes. East Coast Solar installs residential and commercial solar in Andover. Our crew is based in Worcester, 70 miles away. We handle design, permitting, installation, and service in-house, with no subcontractors.
- What's the average electricity rate in Andover?
- Andover homes are served by National Grid, with residential rates typically in the $0.28 to $0.33 per kWh range as of 2025. These are among the highest electricity rates in the United States, which is the main reason solar payback in Massachusetts is shorter than the national average.
- What solar incentives are available in Andover?
- Andover residents qualify for the Massachusetts incentive stack: the SMART production-based incentive, net metering through National Grid, the 15% MA state tax credit (up to $1,000), and exemptions from property and sales tax on the solar system itself. Federal tax treatment has changed with recent legislation and depends on whether the project is residential or commercial, so we walk through what currently applies to your project during the estimate.
- How long does a solar installation take in Andover?
- Most Andover residential installations take 4 to 8 weeks from signed contract to system activation. The on-site rooftop install itself is one to two days. The rest of the timeline is engineering, permitting with the Andover building department, and the utility interconnection process with National Grid.
- Do I need historic district approval for rooftop solar in Andover?
- For roof-mounted panels in the Central Street Historic District, no. The bylaw places roof-mounted solar panels on the same exempt list as storm windows and conventional antennae, alongside similar appurtenances. Ballardvale is the other local district and its bylaw has been going through an update, so confirm the current text for that address before you file. A separate track applies regardless of district: if your property is on the Andover Historic Building Survey or the state inventory, the Preservation Commission reviews the building permit application.
- Can I put a ground-mounted system on my Andover property?
- Yes, within limits that are tighter than most people expect. A small-scale accessory ground mount is allowed by right in every district, but panel area is capped at 1,000 square feet in the Single Residence A and B districts and 1,750 square feet elsewhere. It has to sit in a side or rear yard, never a front yard, no closer to a rear lot line than ten feet or the system height, whichever is greater, and no taller than fifteen feet in a residential district. Anything larger needs a Planning Board special permit, and in residential districts the system size is then limited to what you actually consume on site over a year.
- I heat with oil and may switch to heat pumps. Should that change my solar system size?
- Yes, and it is a common Andover question given how much of the town is still on fuel oil. A heat pump conversion can add several thousand kilowatt hours a year to an electric bill, so an array sized against a pre-conversion bill will end up too small. We model the post-electrification load, including an EV charger if one is planned, and size to that. Oversizing has its own limits under net metering rules, so the target is the future load rather than the largest array the roof can hold.
