We speak

English

SunFlower has over 8 years of hands-on experience designing and installing solar across New Hampshire, Maine, and Massachusetts. We’re locally owned, deeply rooted in the Lakes Region of NH, and proud of our strong reputation for quality and service.
Most residential solar systems are installed in 2–3 days. The full process, from permitting to inspection, typically takes 8-10 weeks, depending on your utility and town requirements. We handle everything from start to finish.
No, but costs have come down drastically and we are still seeing sub 8 year paybacks for residential solar only projects. Battery costs continue to drop as well.
We’re local, responsive, and focused on long-term relationships, not quick sales. Our small team handles every detail with care, and our owners are personally involved in every project. We are still working with our customers from 8 years ago.
In most cases, the simple answer is yes. We would want to make sure the type of generator you have is compatible with the system. In addition, we would want to design the system with any future plans if possible such as battery storage, ev charging, etc.

Why Choose SunFlower? At SunFlower, solar is handled with care from the first conversation through long-term system support. We take a hands-on, locally focused approach that gives homeowners and businesses a better experience from start to finish. Personalized Design, Not One-Size-Fits-All We provide clear education and custom system designs so you can understand your options and make a confident decision based on your property, goals, and budget. We Manage the Entire Process From permitting and utility coordination to final approvals, we handle the details so the project stays organized, efficient, and easy on your end. Trusted Installation, Proven Workmanship We work exclusively with Collins & Sons Electric LLC, bringing experienced solar installation and master-level electrical expertise to every project. Hands-On Oversight We stay involved during installation to help ensure the system is built as designed, with close attention to quality, accuracy, and overall project execution. A Smooth Path to Turn-On Once installation is complete, we handle testing, monitoring setup, and final documentation to move your project efficiently toward Permission to Operate. Support That Continues After Installation We assist with REC enrollment where applicable, provide system monitoring support, and remain available long after the install is complete. With SunFlower, you are not just buying a solar system, you are working with a local partner committed to doing the job thoughtfully, communicating clearly, and standing behind the work for the long run.

Excellent Service

We have a big, multi-needs family, and needed a large roof installment. It surprised us all to find that we had an unusual strapping arrangement underneath our metal roof. We had to change plans partway through, but with the help of some expert help, our roof was secured and our solar panels were securely and beautifully installed by our deadline. SunFlower worked with us, communicating clearly through each step, ensuring that our system would last, as well as was up and working when we needed it. They are familiar with our communities here in New Hampshire; our weather, our electrical services, our diverse locations, and our unique needs. They plan accordingly. Excellent Service!

Why I selected SunFlower

Just signed the contract so all I can review is the process so far. Vincenzo Sisti of SunFlower was always available during the evaluation of their proposal. He answered every single question in detail. All SunFlower #s checked out in my personal calculations. And these were very good #s. We worked on the panel details (black/black was very important to us) and went through several panel layout options. So basically I used a lot of Vincenzo's stime, never felt rushed, and all information checked out. That's why we chose them. Next review once the system is operational.

Quality work and transparent communication.

This team did a great job with our solar installation. From the original site visit through the final hookup the process was clearly outlined and communicated and there were no surprises along the way. Overall we're very satisfied with the work performed and we're confident that if we have any future questions or needs this team will respond in a timely and professional manner.

Disappointed

I held off writing a review for a few years because I had a falling out with themSunflower. But I feel that somethingshouldbe said in case others have had similar experiences. It started with the delays. Our installation was scheduled for September and kept getting pushed out. It didn't get installed until February. Being a ground array, I was concerned with the mess it would leave behind with a mid winter installation but was assured that they would return as soon as the ground thawed in the spring. I held back $2K for insurance and because I was unhappy with making monthly payments for a system long before it was completed. Spring came. I texted the owner about getting the landscaping cleaned up and grass seeded but was ignored. So I reluctantly did it myself. Has soil delivered, spread it. graded, seeded, etc. Since the completion of the installation, and to this day, I never received any orientation on how to care for, maintain, or service the system. The system works fine still after a couple years and it was the best quote at the time but you get what you pay for and concerned with longevity.

Quick, easy and friendly!

Vincenzo was great to deal with! He was quick to respond and was very cordial in answering my many questions. He schedules things quickly, pulled all the necessary permits, showed up on time and had the work done in a timely manner. I recommend Sunflower to anyone with solar needs in the NH area!

Great Company

A great team of hard working folks who do an amazing job. They are extremely knowledgeable and very willing to answer any and all questions and potential concerns you have. Highly recommend the Sunflower team! We also haven't had to pay an electric bill since switching to solar as we carry a credit balance generated during sunny times, to cover stormy seasons.
