Sunergy Solutions Overview
Sunergy Solutions LLC is a New Hampshire-based solar and roofing company that has built one of the most impressive customer satisfaction records in the region since its founding in 2020. Operating out of Londonderry, NH with seven offices across Connecticut, Massachusetts, Maine, New Hampshire, Rhode Island, Vermont, and Virginia, Sunergy covers more ground than any other company in our review — making them one of the few options for New England homeowners in less-served states like Vermont, Maine, and New Hampshire.
The company's independent review record is exceptional. With 146 reviews on SolarReviews averaging 4.91 out of 5 — all five-star ratings — Sunergy demonstrates a consistent ability to deliver on customer expectations. That level of satisfaction across a geographically diverse service area reflects strong operational discipline. Sunergy holds Enphase Platinum Installer certification, placing them among the top tier of Enphase-authorized contractors in the country. They are also NABCEP certified, the solar industry's most rigorous professional credential, and hold BBB A+ accreditation since 2021.
Sunergy's scope extends beyond solar and roofing to include gutter installation and repair, EV charging stations, and battery storage systems. This positions them as a home energy and property services company rather than a pure solar installer — which can be a genuine convenience for homeowners looking to address multiple projects under one roof, or a potential concern for those who prefer specialists focused on a narrower service set.

Pros & Cons
Pros
- 146 five-star reviews on SolarReviews (4.91/5) — one of the strongest independent review records in the region
- Enphase Platinum Installer status — top-tier certification from one of the leading inverter manufacturers
- NABCEP certified technicians — the solar industry's most rigorous professional credential
- Broadest service area of any company reviewed — 7 states including all of New England plus Virginia
- 7 regional offices for local presence across a wide territory
- BBB A+ accredited with no complaints on record
- Offers gutters and EV charging alongside solar and roofing for a complete home upgrade
Cons
- Founded in 2020 — only 5 years of operating history vs. Evergreen's 4+ years with deeper New England roots
- Uses subcontractors for roofing in some states — less integrated than bundle-first specialists with in-house crews
- Does not offer solar leases or PPAs — limits options for homeowners who can't qualify for solar loans
- Specific roofing material brands not prominently disclosed — harder to compare warranty terms directly
- No $0 down ownership options confirmed — financing options are more limited than some competitors
Customer Review Analysis
Sunergy Solutions maintains one of the strongest review profiles among New England solar installers, with a 4.9 Google rating across approximately 200 reviews and near-perfect marks on SolarReviews and EnergySage. Customers overwhelmingly praise the company's communication, no-pressure sales process, and fast professional installations. The main considerations are slightly higher pricing and a relatively short operating history.

What Customers Praise
- Exceptional communication — named reps (Mike Lynch, Devyn Cote, Brandon Kent, Angelo, John Parlatore) praised by name for responsiveness and availability
- Consultative, no-pressure sales approach with detailed 3D modeling and personalized system design
- Fast, professional installations frequently completed ahead of schedule with in-house crews
- Premium equipment (Q Cells panels, Enphase IQ8 microinverters) backed by industry-leading 25-year manufacturer and 20-year workmanship warranties
- Strong owner involvement — company president personally resolves escalated issues
What to Watch For
- Pricing tends to run slightly higher than competitors, though reviewers consistently report the quality justifies the premium
- Relatively young company (founded 2020) with limited long-term track record on warranty fulfillment
- Some reviewers noted weather and permitting delays, though these are typical for New England installations
- Limited evidence of post-activation support quality — one reviewer reported a system failure that required presidential intervention to resolve
- Nearly uniform 5-star ratings across all platforms suggest active review solicitation from satisfied customers, making it harder to gauge the full range of experiences
Sunergy Solutions LLC, headquartered in Londonderry, New Hampshire, has built a remarkably strong reputation in a relatively short time. Founded in 2020 and BBB-accredited since 2021, the company has accumulated over 200 Google reviews at a 4.9-star average and 146 reviews on SolarReviews at 4.91 stars — numbers that place it among the most reviewed solar installers in the region. The company holds NABCEP certification and SEIA membership, and its A+ BBB rating with no visible complaints reinforces a pattern of operational quality.
The most consistent theme across reviews is exceptional communication. Customers repeatedly name individual sales representatives — Mike Lynch, Devyn Cote, Brandon Kent, Angelo, John Parlatore, and Jeff Deming — praising their responsiveness, patience, and willingness to educate without high-pressure tactics. Multiple reviewers specifically note that Sunergy stood out from competitors during the quote-comparison phase for its consultative approach, including detailed 3D modeling of proposed systems. The installation experience draws similarly strong feedback: homeowners describe fast, clean, professional crews that frequently complete work ahead of projected timelines, even during New England's challenging weather seasons.
On the equipment side, Sunergy installs Q Cells panels paired with Enphase IQ8 Series microinverters — a premium combination backed by a 25-year manufacturer warranty and a 20-year workmanship warranty, the latter being among the longest in the industry. Several reviewers noted they chose Sunergy despite receiving lower quotes from competitors, citing the superior product lineup and warranty coverage as deciding factors. Worth noting: as a company with only about five years of operating history, long-term warranty fulfillment remains unproven compared to more established competitors. Additionally, one EnergySage reviewer reported a system failure on New Year's Eve, though the company president personally intervened to resolve the issue — a response that earned a 5-star rating despite the initial problem. Homeowners considering Sunergy should weigh the strong short-term track record against the inherent uncertainty of a younger company's long-term service capacity.

Roofing Performed By
Uses regional subcontractors for roofing work in some service areas
Sunergy Solutions offers solar installation, roofing replacement and repair, and gutter services — which can be combined as part of a home energy improvement project. Here's what the program typically includes:
- Solar System: Sunergy is an Enphase Platinum Installer, indicating their primary inverter partner is Enphase — a leading manufacturer of microinverter systems that provide panel-level monitoring and performance optimization. They also work with SolarEdge inverters and install panels from well-regarded brands including Q.Cells, Panasonic, and LG Solar. All solar equipment carries a 25-year manufacturer warranty.
- Roofing: Sunergy provides full residential and commercial roofing replacement. The company uses licensed roofing subcontractors in states where required, which is standard practice for solar companies with wide geographic coverage. Roofing is coordinated with the solar installation to minimize disruption and ensure proper flashing and penetration protection.
- Gutters: Gutter installation and repair is included as an optional add-on service — a genuine convenience for homeowners undertaking exterior home work.
- Battery Storage (Optional): Enphase battery storage systems, Tesla Powerwall, and LG Chem batteries are available as add-ons for homeowners who want to store excess solar production for nighttime use or grid outages.
- EV Charging (Optional): EV charger installation is available for homeowners looking to electrify their transportation alongside their home energy upgrade.
- Workmanship Warranty: Sunergy backs their installations with a 20-year workmanship warranty covering labor and installation quality on both roofing and solar components.
One important note on roofing: per their BBB disclosure, Sunergy uses licensed subcontractors for roofing work in states where required. We recommend asking your representative who specifically will perform the roofing work on your project, whether they are Sunergy employees or subcontractors, and how warranty claims are handled in each case.

Pricing & Financing
Sunergy Solutions takes an owner-focused approach to financing. The company actively recommends purchase over leasing and does not offer solar leases or PPAs — a deliberate business philosophy rather than a limitation of their financing relationships.
- Cash Purchase: Pay for the system upfront and own it outright from day one. Sunergy recommends this path for homeowners who can absorb the upfront cost, as it maximizes long-term savings and preserves full access to federal and state tax incentives.
- Solar Loan: Finance the system through Sunergy's lending partners. You own the system, capture applicable incentives including the federal 30% Investment Tax Credit, and pay off the system over time. Specific loan terms and rates vary by lender and creditworthiness — ask your representative for current options.
Sunergy does not offer solar leases or Power Purchase Agreements (PPAs). The company's position is that ownership structures provide meaningfully better long-term value for most homeowners. If you're a homeowner who specifically needs a $0-upfront lease or PPA structure, you'll need to explore other providers.
Sunergy does not publish standard pricing; every project is sized and priced individually based on your roof, energy consumption, shading, and location. Contact them at (844) 427-6527 or through their website to request a customized assessment.
Note: Solar incentives — including the federal 30% Investment Tax Credit and state-level programs — vary by state and financing structure. Sunergy's team can clarify what incentives apply to your project during your consultation.

Our Take on Sunergy Solutions
Sunergy Solutions has accomplished something remarkable in just five years: they've built an operational footprint spanning seven states and a customer satisfaction record that most solar companies never achieve. The 146 five-star reviews on SolarReviews — all five stars, with an average of 4.91 — reflect genuine customer satisfaction, not just a handful of well-timed referral requests. For New England homeowners in New Hampshire, Vermont, or Maine who struggle to find experienced local solar installers, Sunergy is one of the few companies with real regional infrastructure and a proven track record of delivery.
The Enphase Platinum Installer credential is worth noting. Enphase is one of the two dominant inverter manufacturers in residential solar, and Platinum status reflects high installation volume, technical training, and demonstrated customer satisfaction on Enphase systems. That kind of manufacturer certification is a meaningful quality signal, particularly for homeowners who want panel-level monitoring and the reliability of a well-supported microinverter system. NABCEP certification adds another layer of professional credibility.
Where we'd encourage careful conversation: Sunergy's roofing work involves subcontractors in some states — common for companies with wide geographic coverage but worth understanding before signing. Ask specifically who is performing the roofing work on your project. Additionally, Sunergy's financing options are narrower than some competitors — they don't offer leases or PPAs by choice, which is a principled position but limits options for homeowners who need a $0-upfront structure. Their workmanship warranty of 20 years is solid, though it falls short of Evergreen's 25-year standard. Founded in 2020, they're also one of the newer companies in our review — the five-year track record is encouraging, but it's shorter than more established competitors like Trinity Solar (1994) or Evergreen Solar.

Frequently Asked Questions About Sunergy Solutions
Does Sunergy Solutions serve New Hampshire, Vermont, and Maine?
Yes — Sunergy Solutions has the broadest service area of any company we reviewed, covering Connecticut, Massachusetts, Maine, New Hampshire, Rhode Island, Vermont, and Virginia.

Most other bundle specialists focus exclusively on MA, CT, and RI, making Sunergy one of the few options for New England homeowners outside the core three states.
What solar equipment does Sunergy Solutions use?
Sunergy Solutions is an Enphase Platinum Installer — their primary inverter partner is Enphase, a leading manufacturer of microinverter systems that provide panel-level monitoring and performance. They also install SolarEdge inverters and work with panels from well-regarded brands including Q.Cells, Panasonic, and LG Solar. All solar equipment carries a 25-year manufacturer warranty.
Does Sunergy Solutions offer solar leasing or PPAs?
No — Sunergy Solutions does not offer solar leases or Power Purchase Agreements (PPAs). The company's philosophy is that ownership structures provide better long-term value for most homeowners.

If you specifically need a $0-upfront lease or PPA, you'll need to look at other providers.
Does Sunergy Solutions replace roofs as well as install solar?
Yes — Sunergy Solutions offers roofing replacement and repair alongside solar installation, plus gutters. Roofing work in some states may be performed by licensed subcontractors rather than direct Sunergy employees — which is standard practice for solar companies with wide geographic coverage. We recommend asking your representative who specifically performs the roofing work on your project and how warranty claims are handled.
What certifications does Sunergy Solutions hold?
Sunergy Solutions holds several meaningful credentials: Enphase Platinum Installer status (top-tier certification from one of the leading inverter manufacturers), NABCEP certification (the solar industry's most rigorous professional credential), Solar Reviews Elite Installer status, BBB A+ accreditation since June 2021, and membership in SEIA. These credentials collectively indicate a company that meets high standards of technical competence and business practice.
How long has Sunergy Solutions been in business?

In five years, they've grown to seven offices across New England and Virginia and accumulated 146 five-star reviews on SolarReviews.
