  • The installation process went well. The adjustments made as needed. Highly recommend E2 Solar.

    “The E2 team installed a pedestal tracking solar system in our yard. Everything went really well. The team was receptive to answer questions. The installation process went well. The adjustments made as needed. Highly recommend E2 Solar.”

    Susan, Westport


    “My response to all questions about your company's work is EXCELLENT!”

    Maggie, North Falmouth

  • The most important thing of all is that "You're Going Green." This is a good investment, go for it! Thank you once again E2 Solar for a job well done.

    “My experience with E2Solar has been excellent from start to finish. They surveyed the site and gave a detailed presentation on the proposed system, showing number of panels and placement, the cost and payback estimates including federal and state tax credits, a state grant, SRECS and monthly bill savings. At the completion of the project E2Solar provided a user manual of a copy all signed papers and system documentation, The system E2 Solar, Inc. installed is an 8.28 kW grid tied photovoltaic system consisting of 36 SunPower 230 watt modules attached to the south facing roof of my home. The solar array is tied to the grid using a SunPower 7000m inverter mounted in my garage. Electrical production is monitored with a SunPower Monitoring System. My system has been running since 9/22/2011. The following data was compiled as of the May 2012 bill (5/24/2012). The system has generated 7664 KWH vs. an estimated 7203 KWH from the chart provided in the post implementation documentation. This is about 6% higher than predicted. The NStar bills to date have totaled $78.29 vs. $1347.09 for the same time a year ago. I expect to generate enough extra KWH during the longer days to cover the NStar cost in the winter. My current credit balance at NStar is $122.56 or 567 KWH. I have generated 7 SRECS to date, 2 have been paid at $540 each (net $502.20 after sales commissions). The cost of my system was $46,598 of which $21,132.49 (Federal Tax credit $14031, State Energy Grant $3750, State Tax credit, $1000, Savings on NStar bills $1347.09 and SRECS $1004.40) has been paid back in the first year. The yearly savings of NStar bills ($2249.13) gives me a 4.9% return on the $46598 in the first year and it increases each year as the balance declines. I expect in a little over 4 years to have paid back my original investment and for at least the next 6 years to be profiting from the sales of SRECS and electricity cost savings to the tune of $8000 to $10,000 a year and have the original money to invest all over again.”

  • Terrific experience from start to stop with E2 Solar

    “We had a terrific experience from start to stop with E2 Solar at our home in Orleans. Highly professional and nice people to work with, and an excellent combination of service and (Sunpower) product.”

    Charles, Orleans

  • Honest, competent, reliable

    “Honest, competent, reliable - and, without question, the best customer service manager I've ever encountered, the great Desiree Revoir.”

    Daniel, Wellfleet

  • Further investigation will confirm that E2-SOLAR of Dennis, is the only company to manage your project.

    “Anyone considering the installation of solar panels on Cape Cod should very carefully evaluate both the the company AND, most importantly, the product itself. Performing your due diligence provides more than peace of mind; it will clearly show you that one product is vastly superior to anything else on the market. That product is the [] panel produced by SUN POWER. Further investigation will confirm that E2-SOLAR of Dennis, is the only company to manage your project. The combination of E-2 and SUNPOWER will be one of the best investments you ever make!”

    Seth, Chatham

  • E2 has exceeded our expectations.

    “E2 Solar installed our SunPower system one year ago, and I could not be happier. The installation went exactly as they promised, and there were no issues. Desiree led us through the maze of approvals, and was there to answer any questions. The system has produced more than they estimated, and we have not had an electric bill since the installation. It was estimated that our system would produce 8100 KWH, but we actually produced around 8800 KWH. E2 has exceeded our expectations.”

    David, Centerville

  • I wish all companies were as competent and professional as they are.

    “We installed solar panels late last summer. We contacted 3 other solar dealers and E2 gave us the best deal. The other installers only looked at our house via satellite, and quoted us based on that. E2 came out and measured our roof. They were able to install more panels than the other companies which generates more solar and more savings for us. Throughout the whole process they were reliable and professional taking care of all the details. The numbers they calculated for savings were right on. I would positively recommend using E2. I wish all companies were as competent and professional as they.”

    Louise, S. Dennis

  • They have increased my expectations and unfortunately decreased my satisfaction with other home improvement professionals!

    “In my years as a home owner I have not had the pleasure of working with a more courteous, attentive, thorough, and helpful crew than those at E2 Solar. The only downside is that they have increased my expectations and unfortunately decreased my satisfaction with other home improvement professionals!”

    Maria, East Dennis

  • E2 Solar is an outstanding PV installation company.

    “E2 Solar is an outstanding PV installation company. High quality product, close attention to detail, and good customer communication produces a very satisfied customer.”

    Peter, Brewster

  • It was a very nice service to know that our installer was concerned about his work and his customers.

    “We were extremely impressed when one of Jason's staff members came by one year after installation to check all the fittings, etc. to make sure that everything was intact and in order. We didn't request this nor did we know they were going to come. It was a very nice service to know that our installer was concerned about his work and his customers. Very nice customer service.”

    Marcia and Jim, Truro

  • Highly recommend E2 Solar!

    “Had our Sun Power solar system turned on recently in Barnstable Village and we are loving it! It generates plenty of power to run all electric appliances, central AC and charge my Tesla. E2 Solar made the process simple and their professional crew was outstanding. Something to think about if you live on Cape and want solar is our limited amount of sun. Even though Sun Power panels are a premium product and priced accordingly, they are the best at capturing diffuse light (when it's cloudy) and that was very important to us. Highly recommend E2 Solar!”

    Vince, Barnstable

  • I haven’t paid an electric bill in 6 months! Recommend them proudly without hesitation.

    “I have had the good fortune of working with E2 Solar under two different occasions and circumstances. After a competitive bidding process, E2 Solar was chosen to complete the 31.96 kilowatt system at Thankful Chases Pathway, located in Harwich, MA. This project was a new development and E2 Solar worked with the development team from the planning stages through completion of the project. Through the entire process all of the staff members were professional, competent, informed and always available to answer any and all of my millions of questions clearly. They were always patient when explaining all the new terminology which accompanies the whole process from the technical aspects to the SREC process. This same attention to detail and pride in workmanship was still present when they completed the photovoltaic system on my home a couple of years later. Thanks to them and the Photovoltaic panels on my roof, I haven’t paid an electric bill in 6 months! Recommend them proudly without hesitation.”

    Abigail, Wellfleet

  • I am impressed by their customer service.

    “I am impressed by their customer service. Whatever you paid them over the big outsiders, it’s worth it!”

    Nancy (sister of a customer, watching over house in her absence), Falmouth

  • This system is flawless!!

    “Jason is excellent. Really knows the products and the process. Answered any and all questions that we had. we have recommended E2 Solar to many people interested in Solar Energy! The savings have been amazing and each month when I log our info onto the MassCEC Production Tracking System (PTS), I snicker at the part of "service costs." This system is flawless!!”

    Steve, West Barnstable

  • Very pleased with all aspects of our installation.

    “Great to work with from start to finish. Very professional, personable and knowledgeable crew. Very pleased with all aspects of our installation.”

    Janice, Truro

  • Couldn't have gone smoother!!

    “The process from start to finish couldn't have gone smoother!!”

    Keith, Yarmouth

  • Start to finish great service, great panels and warranties.

    “Start to finish great service, great panels and warranties.”

    Janet, Falmouth

  • I have given and will give references

    “I thought you may want to know our level of satisfaction after 3+ years of service. I assume you already have looked at the records. We were promised 8573. 2017 did 8770 and 2018 – 8940. So we are very pleased. I have given and will give references.”

    Russ, Falmouth

  • Everyone on their team made the process easy.

    “This is the second house I had Jeff and E2 Solar install solar panels on. The first was in 2013. That system has already paid for itself and we have had ZERO problems. We just had the all black panels installed on our new house and they look great. SunPower has some of the best panels on the market and E2 is a great installer. Everyone on their team made the process easy. With the cost of electricity on the Cape, we are looking for another quick return on our investment.”

    Wesley, Eastham

  • E2 Solar stands out as the best there is

    “We are thoroughly satisfied with our SunPower system and the service E2 Solar has and continues to provide. From their initial sales presentation, to system design, installation and finally management of all system registration and startup requirements E2 Solar stands out as the best there is. You will not find a more accommodating and friendly group of folks who are truly there to support you from your initial decision-making process through to system operation and after. Never was there any pressure to purchase, rather, they have always been there to help.”

    Frank, Dennis

  • Great job guys! Your professionalism, courtesy and expert knowledge is commended and praised. We cannot thank you enough for safeguarding our home.

    “Mona and I would like to take a moment to write how truly wonderful you all are. From the constant email and phone updates to the guys accommodating our audible to install the critter guard around the entire perimeter of the solar array. The three squirrels returned when the guys left and were determined to find a way back into the nest. Eventually they were discouraged and the mother grabbed both juveniles, never to be seen again.”

    John and Mona, Truro

  • I can't say enough about E2 Solar

    “I can't say enough about E2 Solar. They were helpful, professional, and prompt throughout the entire installation process. After installation, they were available for questions and support at a moment's notice. Desiree is a font of knowledge and even contacted me right away when I had an issue on the weekend. The issue - the only problem I ever had with my system - was immediately corrected by their master electrician. He, too, was wonderful. Explained everything in detail, was incredibly personable. And, i love the fact that it is a local business, the owner easily accessible. Coincidentally, I used the owner's wife (A3 Architects) as my architect; she specializes in energy-efficient designs. Can't say enough about her and her work, either.”

    Peggy, East Harwich

  • We would like to give our highest recommendation to E2 Solar of Cape Cod.

    “We would like to give our highest recommendation to E2 Solar of Cape Cod. From the initial meeting with them the entire experience was totally positive in all aspects. They filled out all the paperwork for us, applied for all the rebates and permits, and walked us through the whole process with great professionalism. Their team of installers worked efficiently and cleaned up when they were done. After the installation, the technicians and Jeff Schwartz gave us detailed instructions on the system and remained available to us in case we had any further questions. We were very impressed that when we had an impending hurricane, Jeff e-mailed information to us on what to do if we lost power for an extended period. At one point NStar was doing work in our area and it created a problem with our system and Jeff immediately worked directly with NStar to assure the problem was fixed right away. We have found that E2 Solar has responded to all our questions and concerns immediately and that has been instrumental in our giving our highest recommendation without hesitation to anyone who is considering solar energy with them. We are confident that should you make the decision to go solar, you would never regret it and would be extremely pleased with your decision. Should you like to discuss this further with us, we would invite you to call us for more information.”

    Robert and Judith, Plymouth

  • I could not have asked for a better installation from start to finish. E2 Solar is the Best.

    “I could not have asked for a better installation from start to finish. E2 Solar is the Best. From the initial consult, to the copious amount of paperwork and the actual installation, all E2 Solar employees were enthusiastic, energetic, knowledgeable and genuinely excited about their jobs. Excellent customer service.”

    Lincoln, Brewster

  • I highly recommend E2 Solar to friends and family who show an interest in getting a PV system.

    “I had a great experience with E2 Solar who installed my system just over two years ago. Todd was great to work with for reviewing the shading issues we had, measuring out the roof and providing a schematic of the panel placement to achieve optimal efficiency given the shape of our roof and locations of shade. E2 did a great job explaining the different types of systems, inverter sizing, etc. E2 was also very knowledgeable about the federal and state tax credits as well as other grants and incentives available. When install day came in November of 2014 the team was nice, efficient and happy to answer my questions. The install of my system was completed in two days and they did a super clean, professional job of it. The hardest part was waiting for Eversource/NSTAR to authorize my interconnection. The system is working great and my last utility bill was March of 2015. I highly recommend E2 Solar to friends and family who show an interest in getting a PV system.”

    Nathan, Mattapoisett

  • Your team does good, neat work and without delay.

    “Again, many thanks for what you’ve done on our behalf. While I’m thinking of it, I have recommended your company to our neighborhood and several other as well. What I’ve said is that you are meticulous and easy to work with. What’s more, you listen to what we’d like and do whatever is possible to accommodate. Your team does good, neat work and without delay. You told us when we might expect installation and followed through ‘on the dime.’ You arranged the inspections and made sure they were prompt. Nancy and I can’t thank you enough for all your work on our behalf. If ever you’d like to include us in your list of satisfied customers or list our home among those open for exterior inspection, please feel free to do so. Incidentally, many of our neighbors have commented on how good the installation looks. With appreciation, Chuck”

    Chuck and Nancy, Falmouth

  • And the panels are working great, too!

    “E2 installed solar panels on our house in Chatham in the Fall of 2016. We had received quotes from two other solar companies, and E2's proposal was by far the most complete and professional. Theirs was also the most expensive, but we finally concluded that the additional cost was worth having a product with a better warranty and a better panel degradation rate. We also sensed, based on our experience through the proposal process, that the installation process would be smooth. Were we ever right about that. We have dealt with many contractors over the years, but E2 was by far the most professional, efficient, and transparent. Their entire team, through the entire process, was great. They took care of absolutely every detail. It was simply a pleasure working with them. And the panels are working great too.”

    Robert, Chatham

  • These guys are phenomenal!

    “Desiree is the best! My excellent install team included Paul Talmadge, Paul McGrath, Garrett McGrath, Jamie Unger, Garry Thorpe and Tim LeTourneaux. These guys are phenomenal! E2Solar has been a wonderful experience from top to bottom. Highly recommend to anyone wanting a seamless and professional solar experience. Thanks guys!”

    Peter and Marion, Falmouth

  • This company is great to work with. Thank you, E2 Solar.

    “This company is great to work with - they have given me sound honest recommendations before the project was started. When they showed up for the installation it was professional and friendly. This experience is one that should be shared - it is a local business, I am grateful I chose to support it. Thank you, E2 Solar.”

    Vicki, Falmouth

  • Our system is producing without any problems.

    “Our installation was efficient and easy. We were led with ease through all paperwork and details. Office is informative and approachable. Our system is producing without any problems.”

    Cynthia, E. Falmouth

  • Say what they do and do what they say

    “Very nice people that say what they do and do what they say. Highly recommended!”

    Steve, Harwich

  • Our electric bills monthly are now ZERO. Highest recommendations.

    “Today our electric company installed the new meter which will give us a check each month for the electricity we are making. Guaranteed for monthly payments for 10 Years! In addition, our electric bills monthly are now ZERO. I invite any Cape Codders to contact me for more details. How do we get production on Foggy Days? We do. Cloudy Days? We do. Highest recommendations.”

    Bob, Chatham

  • I am 100% satisfied

    “I had a solar-electric system installed by E2 Solar in 2017 and I expanded it in 2019 to cover almost all of my needs for electric power, cooling and heating. I am 100% satisfied and have recommended E2 Solar to several neighbors. I love the SunPower website and use it daily to monitor the performance of my system!”

    Ian, Falmouth

  • You Clearly Stood Out, I Absolutely Love the System

    “"I think I may have over analyzed this but when I compared your answers, assumptions, thoroughness, etc to others, never mind the time you spent answering my questions, you clearly stood out." And 5 months later... "I wanted to circle back to you after the installation. I absolutely love the system, I know it has only been 2 days :). The installation team was extremely professional, took the time to answer all my stupid questions, and I had many!! I was very impressed with their attention to detail, neatness and you can tell everything they do, they want to look neat and orderly. The electric, conduit, racking, etc. was all done with appearance in mind and they worked with me to place everything so it blended in with the house etc. I love the monitoring system. Couple of thoughts already, I never realized how much power the irrigation pump uses, it was the old pump that fed the whole house from the well before we switched to town water except the irrigation system, definitely an opportunity to right size the pump!! Have got a couple of quotes so far on the mini ductless heat pump systems, hoping to get a couple more and do when the cash is available. Thank you so much for your effort and I know I made the right decision on you E2."”

    Mike, Chatham

  • A wonderful local company to deal with.

    “Responsive, helpful, knowledgeable -- made the process easy. A wonderful local company to deal with.”

    Susan, Wellfleet

  • As an aside, before I entered into the contract, I researched the sunpower panels, and was able to confirm that they are of the highest quality.

    “I am pleased to have this opportunity to give an excellent review to E2 Solar. Both Todd and Desiree were extremely helpful in assisting me in choosing a system which met our needs. They were both very knowledgeable and very patient in working through this process with me and my wife. The installation of the system was also an excellent experience. It was carried out in a timely fashion by a crew which was both highly professional and very pleasant. They took the trouble to leave the site around my house in exactly the same condition as they found it. As to the system itself, it operates flawlessly. I had my first negative electric bill last month, and I am looking forward to continued substantial electric savings. Everyone involved took the trouble to be sure that we understood how the system operated, and that we had the resources available to enable us to to manage the operation of that system. As an aside, before I entered into the contract, I researched the sunpower panels, and was able to confirm that they are of the highest quality.”

    Richard, Plymouth

  • Very professional, courteous and efficient

    “Very professional, courteous and efficient. Readily available and happy to answer any questions or problems.”

    Terry, East Falmouth

  • I would like to take this opportunity to thank E2 Solar for the professional job they performed on our 9kw residential PV system.

    “The team was very well informed and easy to work with through the whole process. I would highly recommend them to anyone interested in a residential or commercial system. You won’t be disappointed at all by their expertise and attention to detail. Feel to contact me as a reference for more information.”

    Tony, Brewster

  • You should be so lucky as to have a company like E2 representing you everywhere!

    “I interviewed and got quotes from five solar companies, including E2 Solar (the sole SunPower affiliate). From the moment their Site Analyst, Jeff Schwartz, stepped into my home, I was impressed. One of the companies pushing the LG panels had put together a very professional presentation and quote, but Jeff took it to the top rung of the ladder. He knew how to address every question I posed, he was prepared, AND, he went up on my roof with a light meter! No one else assessed the house in situ. All their proposals came from Google Earth shots of the property. The day to day programming and administrative work fell to Desiree. She was great, she listened to my scheduling needs and produced as promised through all phases of the project. I reserve my highest accolades for the installation crew: Paul McGrath, Gary Thorpe, Paul Tallmadge, Tim Letourneau, Jamey Unger, and Garrett McGrath, were fabulous. They were timely, fastidious, detailed in everything they did - to call them a well oiled machine would be close to an understatement. I mean really, this may be the first time in my life I have remembered all the names of a crew working on any of the homes I have owned. You should be so lucky as to have a company like E2 representing you everywhere!”

    Seth, Chatham

  • As an E-2 Solar customer who now has panels on her roof, I can only say that I would recommend this company to anyone considering solar energy.

    “E-2 Solar is a great company to work with. Their staff is friendly, knowledgeable, and has great follow through. When we started the process we were looking for an education about solar energy and to decide whether one we definitely wanted to use solar and two how to choose the right solar company. Jeff of E-2 made it very easy, he came out described the process, took extensive measurements and light readings. We had other companies over to get the same education, but found there was a big gap in knowledge and follow through. Once we accepted E-2 as our solar company of choice, Jeff came back out and very thoroughly explained the process in great detail. As an E-2 Solar customer who now has panels on her roof, I can only say that I would recommend this company to anyone considering solar energy.”

    Chip and Jaime, Orleans

  • This is a comfortable, respectful business to work with.

    “As with prior reviews, a highly professional, very knowledgeable and accessible group of people. All contacts are answered within 24 hours or less. I had estimates from 3 companies and chose E2 because of a stronger warranty and the comfortable accessibility of the staff. This is a comfortable, respectful business to work with.”

    Amy, Truro

  • Five stars, E2 Solar is the way to go

    “I had E2 Solar install 10 345W SunPower panels at my Eastham home in October 2016. I've averaged 4677 kWh generated per year. The E2 crew was professional, helpful and friendly through the whole process. Rooftop installation was only 2 days. The installation looks great, with clean hidden wiring unlike some others you see. With the different state programs and SREC credits it's about 5-6 years to repay the low interest loan (instead of an electric bill) then free electricity for 20+ years! Worth it to pay the extra for the quality SunPower panels. Five stars, E2 Solar is the way to go.”

    Ian, Eastham

  • Great Company, professional crew

    “Great Company, professional crew. It's like dealing with a small company vs. a huge conglomerate.”

    Andrew, Harwich

  • I feel so lucky I choose them to do my solar

    “E2 solar is top notch...knowledgeable, professional, with excellent individualized customer service! I feel so lucky I choose them to do my solar. I recommend them highly!”

    Rosemary, Wellfleet

  • THANK YOU, E2, from a more than satisfied customer!

    “In 2014, 34 years after purchasing my home, my dream of going solar has come true! Originally built as a cranberry storage shed in the mid-1800s, my home also served as a school for a time, before being converted to a house in 1923 when rural electrification came to Route 6A. This year, a major snow storm caused a large tree limb to fall on the original 1923 power and telephone lines, pulling down the old poles between Main Street (Route 6A) and my home. I was completely OUT OF POWER! It turned out to be a blessing in disguise as I quickly realized that new service would be needed to deliver the solar-generated power I would be producing to grid when E2 Solar installed my photovoltaic system, which was already scheduled for this spring. On May 19th, the E2 Solar team arrived to install my 12 solar panels! The beginning of the dream was coming true! The team was very efficient and safely installed the racks for the panels on the 19th, the panels themselves on the 20th, and the inverter and delivery system and meter on the 21st! I was SO excited, and was hoping that NSTAR could come and install the bi-directional meter in time for the Summer Solstice on June 21st – the longest day in the northern hemisphere. Happily, NSTAR installed the new meter on June 16th, and my solar generated electricity on the longest day of the year was measured against my usage! This was a LONG winter and a beautiful spring on the Cape, and realizing this dream, with the help of all of the E2 staff has truly made me overjoyed to be producing clean power not just for myself, but for us all! The BEST part is that if the power goes out, I’ll have backup from the two solar-powered outlets on my Sunny Boy inverter to run necessities like AC and the refrigerator! THANK YOU, E2, from a more than satisfied customer!”

    Dr. Marsha, Barnstable

  • I couldn't be more thrilled with this exceptional company and I'm reaping the payback over and above my expectations.

    “Stellar customer service is not a term I have used very often but in the case of Desiree at E2 Solar and her team of associates, its the first thought that comes to mind. I researched 3 other companies who offered less expensive solutions and there is no doubt that had I signed up, I would have received a less than satisfactory outcome. I couldn't be more thrilled with this exceptional company and I'm reaping the payback over and above my expectations.”

    John, Pocasset

  • I can't think of one area where E2 didn't excel

    “We literally just turned our solar system on yesterday - so I don't have a history yet, but our experience with E2 has been outstanding from beginning to this point. Their sales person was thorough, knowledgable and we never felt we were being pressured or rushed. They were willing (and not every provider is) to have their engineer come and go up on our roof (in addition to the satellite estimate for production) to inspect our shingles, etc. - they were 22 years old and needed to be replaced (which was not unexpected), but he also identified some other things to address. Other vendors wanted us to sign the contract before they'd do that! E2's in-office administrator has been relentlessly helpful, friendly, knowledgable and has made getting through the applications and approvals (from the State, power company, etc) a non-issue. She has taken a lot of time to explain things and help us navigate what can be very confusing details as you get going. E2's installation crew was, if anything, over-qualified. There were three certified master electricians on site (as required by law for the size of the job). Apparently, not every company fully complies with this requirement. Their installers made a point of working around our concerns for ground-level gardens and the house and the whole thing happened in a few days with virtually no disruption to us. I can't think of one area where E2 didn't excel. I can't speak to longer term service or quality, but we went with them because we believe that SunPower offers a better quality product and E2 is local and have been around. Plus, three of our friends/neighbors are working with them as well - in numbers? An unqualified rave so far!!!!”
