Just had a solar system installed by Sundog. The entire team was very helpful, responsive, and professional. Very happy with the entire process.

We had a 7.25 kW array installed this summer as well as two mini-split units. The design was done professionally and thoughtfully. The installation happened ahead of schedule and we've been loving those *sunny* days just a little bit extra ever since. Thanks!

I was going to install multi-HVAC system in my house. Their rep did a site visit, made a quote, thus we made a contract with them and sent the deposit, which took over a month. In the morning of the installation day, the engineer came in and said they misevaluated, thus we need to install one less unit than the original plan and need to pay additional $550, or same number of unit as the quote for an additional $3,700 for additional outdoor unit. While looking at their reviews at solarreviews-dot-com, I just found that we are not the only case with such experience from Sundog. Sundog does not seem

I emailed several solar installers throughout Eastern and Bangor Maine about an installation of a small array at our camp. While the installation was too small of a project for Sundog Solar, Laura at Sundog gave me information on a website that sells and designs such systems and the names of local installers who may help.
This was the type of service that you hope for, but sadly seldom get today.

Sundog installed our 5 kw system about a year ago. They were awesome to work with and completed the job on time. They handled all of the applications, paperwork, etc. The transition to solar was totally painless and seamless. Our system is working as expected producing all the power we need - don't let anyone tell you solar doesn't work in Maine!

We love our system - provides all our electricity, 90% HVAC (3 heat pumps) & powers our EV & PHEV. Couldn’t be happier!

I contacted Sundog about an electric vehicle charger installation in early July. The sales rep I spoke to said he’d have a quote for me by “the end of the day tomorrow.” Great. Thank you! A week passes with no quote. I call back and a different sales rep apologizes and promises a quote by “the end of the day tomorrow.” Okay. Two weeks pass with no response from Sundog. I call a third time and speak to a third sales rep. Same promise of turn around time on the quote. This time, I get an email back. hooray! The rep requests detailed photos of the house and panel to inform the quote. I provide

After 2+ years, it feels like time to write a review: I installed a 7.9kW array in April 2018, choosing Sundog for the job after estimates and consults with 3 different installers. Danny Piper walked me through every detail on the phone the first time I called, gave me a great education and helpful guidance about how to get the best bang for my buck re size of array, type of inverter, etc. Every person on the Sundog team has been great to work with, from installers to electrician to the people in the office who have helped me sort out some inverter questions remotely. I didn't have cash to buy

We are new to Maine and decided to add solar panels and heat pumps. After researching our options and receiving proposals from several solar installers, we decided on Sundog Solar. Simple reason for our choice was Danny Piper, the owner.
The systems have been installed now for a few weeks and everything is performing as promised. Solar output is exactly what was projected on the proposal. The heat pumps are quiet and effective. The installation was smooth because Danny and his team are good at what they do.
If you are looking for Solar or Heat Pumps, we highly recommend Sundog Solar

Very pleasant folks to do business with, they installed two heat pumps for us all in one day, their team worked together flawlessly, never stopped, neat, polite, stayed late and got it all done, even took off their shoes in the house AND vacuumed. The price was very competitive with other quotes we received, we chose SunDog because they were responsive and they were very patient with my thousand questions.
