Solar installation exactly as promised

From initial sales proposal then quote then installation and follow-on support, Watson Home Solutions earned our trust. They did everything they promised, finished our solar installation on schedule and for the agreed-upon price. Then they followed up with all paperwork we needed to get tax credits and even REC payments. We couldn’t be happier.

Aiden Katis | Natick, MA | 05/21/2024

Great team & product!

I have nothing but great things to say about Brendan, Kyle, and everyone else at Watson Home solutions for solar purchase. They are transparent, friendly, and helpful every step of the way. Great price and value for the expertise they provide!

Sanjay Prabhu | Hopkinton, MA | 02/08/2024

Very happy with the service

I had a great experience with Energy Monster (when I had got my Solar done) Throughout the process, Kyle guided me to the next steps and provided all the documentation and other items needed for the next steps. Very delighted with the smooth experience.

PK | Worcester, MA | 01/24/2024

Satisfied customer

The Wattson team has designed and installed both a 10.1Kw solar array (2019) and a 10.6Kw battery backup system (2023) for our home. The team is very skilled and completed both projects on time and on budget. Could not be happier with the process and outcomes. 5 stars!

Solar panels installation by Energy Monster (EM)

We had our panels recently installed by EM. A friend of mine recommended this company to me and I contacted Kyle Johnson (the key person for my project). I worked with Brenden Hicks who helped me to figure out the size and type of panels. The rest is all history and now we got our system activated in September and it has been working great for the last 30 days. Overall, staff at EM are very responsive and they will work with you throughout the process. It is not a big company and so they will get back to you soon if you contact them. I compared two other companies and picked EM. I believe the team wants to do the right thing to comply with regulations, earn customer satisfaction and grow their business, the best approach in my opinion for success in the long run! Thank you EM!!

Great experience with home solar installation

The whole team at Energy Monster exceeded my expectations for our recent home solar installation. Everyone was very responsive to any questions I had, and did a fantastic job with the design, installation, and activation of our system. I highly recommend this team if you are considering installing a solar system for your home!

Tim S | Webster, MA | 08/27/2023

Good company

Went solar with energy monster. It’s been a a year and I have not had an electric bill. I worked with Kevin who was very helpful. I also have a neighbor who also went forward with solar. These guys are pretty straight forward. A lot of the other companies I was chatting with felt very sales-ey with over inflated numbers. These guys were dead on.

Brian Salley | Holliston, MA | 07/27/2023

Energy Monster Review 2023

We have been very happy with the entire process of our solar project. From the salesman to the Project Manager to the installers , everything has been perfect. Solar was new to me , so I had alot of questions and they were very patient and addressed all of my questions. They still respond to texts and email and phone call even after we have paid for the project . I can not imagine any reason to not select them for your solar installation.

Karin B | Natick, MA | 02/13/2023

Great people to work with; terrific solar installation!

Thank you Energy Monster for completing my solar project from start to finish. Kyle and everyone else on the team were easy to work with, helpful, responsive, and knowledgeable. The price was very competitive, the service was on time (in all of the elements that were within the control of Energy Monster), and the workmanship was excellent. While the project took 2 months longer than was initially anticipated, this was due to the various approvals and aspects contributed by other parties (plus some delay due to winter storms). Now that my system is operating, the solar production is more than I expected for February in Massachusetts, and I'm very pleased. I recommend Energy Monster if you are considering solar.

Nafisa | Worcester, MA | 08/31/2022

Responsive

The team at Energy Monster, starting with Kevin, and all of the office staff and crew members installing, were very professional and responsive. They go above and beyond with everything. If one team member is on vacation, other responded to my queries. I give them more than 5 stars and highly recommend their services. I was able to refer my neighbor, who saved a large amount through Energy Monster

Cesar H | Ashland, MA | 08/17/2022

Best company in the area

I browsed multiple vendors (7 or 8). Of all of them, Energy Monster was the most professional. They came home, flew a drone and provided energy production that was much more accurate than other vendors which simply looked my house in google maps. The installation process was smooth and I was kept informed of all the details as they happened.

JimD672 | Davenport, FL | 01/03/2022

Awesome Solar Array

It's been about a year since I have had my 35 panel (11.2 KW-DC) installed. Energy Monster did a great job installing my solar array of 35 all-black panels and did it all within a day. No issues after a year and they have been very helpful at keeping me up to date with the permitting process up to the utility's permission to connect. In 2021, I have generated over 14600 KWh and only used 12000 KWh, sending a total of 2600 KWh to the grid by December 31, 2021. My house is about 2000 sq ft. They size the array for my house very well.

Kyle and Kevin were very supportive, very through and detail, they made the whole process easy. Thank you guys

Solar experience with Energy Monster

My wife and I had our solar system installed by Energy Monster just about one year ago. The staff at EM were very thorough, answered all of questions, and fully explained the system they thought would be best for us. Once the system was installed, it was turned on July 1st, so we had July, August and September, of extended daylight, which provided us with great production. Fall and winter, with shorter sunlight, obviously not as productive. As of our first spring with solar, March, April, May and June we have produced more than the first 6 months of having the system. We have accumulated a substantial credit with National Grid which will offset the most if not all electric usage in the fall and winter months. We are very pleased with system, all that the Energy Monster Team has provided us. Jim Martin--Hopedale Ma

Ken | Northbridge, MA | 07/17/2021

Professional people and products

Kevin was great to work with. Their product offerings were exactly what we needed, really like the Critter Guard we wrapped the system with. Everything was installed smoothly, great crews.

Jay C. | Townsend, MA | 07/13/2021

Very positive overall experience!

It was a great experience working with the team at Energy Monster to install a roof mounted solar array. After getting proposals from several companies, we chose Energy Monster for a few reasons: positive reviews from other customers, good impression from their sales rep, strong project proposal including equipment and warranties, good price and value. From start to finish the project did take longer than anticipated. But this was mainly due to the fact that we had other projects going on simultaneously as part of the overall solar package. We had trees removed, a new roof put on, and the electrical service upgraded to 200A before the solar installation could happen. Energy Monster did the service upgrade themselves and was supportive while I scheduled the other jobs. Not to mention this was all going on during the middle of a pandemic. Not long after the system was installed and the electric utility company approved it and switched it on, there developed a problem with one of the panels and one of the microinverters. Energy Monster was quick to send someone out to investigate and replace the parts under warranty at no cost and no hassle. It's been almost a year now, and I'm happy to report that the system is operating very well. We're actually projected to surpass our energy production goal. I usually check the solar reporting app everyday to see how well the system is performing and how much power we're making. I'd recommend solar to everyone, and would recommend going with Energy Monster.

Best solar energy company!!

My installation process was very smooth and the production has been great

Zeid Nabulsi | Framingham , MA | 03/23/2021

Great team to work with and they deliver on time!

It was a pleasure working with Monster Energy. They are amazing company.

Jeff from Naples | Naples, FL | 02/24/2021

Total incompetence! Failed install! 11 months & not working!

I thought choosing Energy Monster of FL. was a smart choice to purchase and have installed a Sonnen Battery Back Up System with 6 panel array to add to our existing 25 panel system. Worse choice I ever made! Here are just some of the things they did wrong: *Never checked our house wiring before the actual install - or even afterwards! 9 months later they tell me our house has a "neutral ground loop" & that i should hire an electrician - everyone knows the installer is responsible for this- not the home owner * The wiring in our house- should have been checked for BEFORE the install *Wired the unit incorrectly- we would have failed inspection + very dangerous! *Never tied the old system to the new system they installed (found this out 4mos after the install) *They expected the unit to operate with just 6 panels- which would never have worked properly *Had me re-sign NOC because "they lost the original one" *Hired a new "GM" who promised they would take the system down and out of out house- but then Duane W. this supposed new GM refused to do what he promised- cursed me out and hung up the phone on me *Mr. J Leet the owner has NEVER called or emailed me to apologize or to try to resolve the issue(s) *They never told me at first that all 25 of our original invertors were "dead" the only good thing they did during this entire debacle was to change them for me for free labor *With all the down time the Sonnen has needed battery replacement 2x (luckily under warranty) *The orig installer for Energy Monster (who did not know what he was doing- or maybe he did the shoddy work on purpose....) quit claiming Mr Leet the owner owed him $$$$ The next 2 service techs he sent to our home were NOT certified by Sonnen! No wonder they could not fix it at all- even with Sonnen's help over the phone! Both of these "techies" eventually quit while im still left with out a working system! (turns off after 5mins after being turned back on) WORST CONTRACTOR I HAVE EVER DEALT WITH! Stay away from Energy Monster- do your research better than i did!

Satisfied Customer | 02/20/2021

Pleased with the my solar adventure with Energy Monster

At the beginning of my adventure I consulted with 4 Solar providers and decided wit Energy Monster in the end. After committing with them, I did not have t do anything but watch them do everything from ordering equipment, delivery, permits, installation and the coordination with the activation with my local power company. It was painless.

Lindsey S. | Lancaster, MA | 01/19/2021

Top notch customer service from start to finish

My Husband and I have been interested in going solar for some time. We have done some research on what we were looking for and looked into a few different solar companies. In the end we wanted someone that is local and that will be around for more than a couple years unlike the bigger companies that seem to keep closing their doors. We had the priveledge on working with Kevin Markey. He is very knowledgeable, quick to respond and very attentive to what we were looking for. He sent over the proposal and met all of our requirements (my husband is very picky). The whole procces was very smooth. From the inital site visit to final inspections all that were involved were very professional, curteous, and made us feel safe during these questionalble times (covid). I would HIGHLY recomend Energy Monster to anyone thats looking for a company that will be there answering ALL your questions from start to finish.

Worst Contractor Ever

Our journey with Energy Monster began back in July 2020 when we made the decision to buy the system. That was our biggest mistake. Little did we know that Energy Monster is ill equipped to be doing business in Florida. They are a Massachusetts company that just opened up in Florida. All of their reviews are from Massachusetts, and they use those reviews to mislead potential customers into thinking they are a good contractor. They didn't know how to submit permit applications in Florida. They didn't know how to work with a finance company. They did not communicate. The project was paused and fell behind. Solar panels were delivered without notice and sat in the driveway before being picked up and then delivered again. The project was finally completed at the end of November. We received none of the benefits of solar power during the summer when our A/C runs the strongest. That alone cost us over $1000 as we had to continue to pay the electric company. They don't return calls. They don't let you know about when work will be done. They don't show up even when work was scheduled. They don't tell you anything. This company should go back to Mass. They should not be in business in Florida. If you are considering Solar energy, GO WITH SOMEONE ELSE. You will be very sorry if you contract with Energy Monster.

charlie | 11/08/2020

Professional service from start to finish

I spent many hours researching local solar companies and went through an hour long presentation with another company to gain knowledge about solar power. After getting quotes from several companies and comparing apples with apples, Energy Monster was by far the most professional looking presentation. From there it only got better. Communication was excellent, especially Kyle Johnson, who replied to phone and emails very quickly. Questions and concerns were always responded to. Installation was done without much interference with our new-normal lives. Final inspection and meter installation was completed without any hiccups!

Nick Carter | Somerville, MA | 09/07/2020

Utterly Awful

Over a year ago, we contracted with Energy Monster to install solar panels on our house. The work is still not complete, we have a giant hole in one wall, and an increasing stack of bills from their failure to do their job. Avoid this company at all costs.

Michael Blair | Pepperell, MA | 08/19/2020

Best Investment Ever

While working with Kevin Markey and Daniel Gawrych from Energy Monster was an excellent experience, I wanted to wait a year before writing a review because I wanted to see what the one year "return" would be. It has been better than we could have ever imagined. We have not paid $0.01 for electricity during the past 13 months. Even though there is a monthly payment due each month for the purchase of the panels, the savings from not paying ANYTHING to National Grid, the money we get back each month from the Mass Saves program, the credit that we have built up with National Grid, and the savings we have in our natural gas bill (we installed a heat pump that was almost free after Mass Save rebates to offset heating and cooling costs) are more then the cost of the panels. We would do this again if we move and we would use Energy Monster to do it.

L.C. | 07/16/2020

Great people and quality work from start to finish

I bought a new REC solar panel system from Dan at Energy Monster, he seemed to be the most knowledgable person I've spoken to during this entire process after receiving quotes from 5 other companies. It seems to me that there is a lot of misinformation being tossed around by other companies, beware!! I highly recommend Dan and his efforts in persuading me to use Energy Monster. Very glad I did!

Clermont | Clermont, FL | 07/13/2020

Great services

The team at energy monster has been a great help answering all of my solar power questions Robert provides excellent customer service skills and is an asset to the company. I highly reccomend energy monster to anyone looking for solar power in Florida

Dimitrios S. | Bonita Springs, FL | 05/22/2020

Very smooth and great customer service

After doing a lot of research, comparing different installers and brokers I found Energy Monster. Dan and Mark did a great job not only providing me the best price, including high level LG Solar panels, but also being very responsive and guiding me through the process. Even during this Covid 19 crisis they were able to install the panels after doing the heavy lifting with the paperwork. Panels are producing currently on the higher end of the provided estimate, which makes me happy. Overall great customer service!

Brian Simmons | Wareham, MA | 05/09/2020

Informative and knowledgeable

Best price best equipment

Curtis Starr | Ware, MA | 04/03/2020

Very Happy with my Solar

I have 33 350 watt panels now on the roof, The process was very smooth and the correspondence back and forth has been better than with other companies I tried to work with. They gave me exactly what I wanted and for less than other companies. The week before I had installed new hard wood floors, The electricians that needed to get into the attic took of their shoes when working - Nice Guys The array looks great on the roof and I'm on my way to being electric independent.

Bryan Cotton | Plainville , MA | 03/16/2020

Very Professional

We had 35 335kWh panels installed. The process was extremely straight forward and the craftsmanship terrific. Every roof penetration his a joist hit. Overall the team was very professional, their pricing was extremely competitive and responsiveness very good. What is preventing me from giving 5 stars was the closure was delayed. Half I blame on our town and the inspector requirements and half was Energy Monster keeping focus on finishing the job. Once I helped facilitate, the job and subsequent National Grid meter swap finished quickly.

Panda | 03/05/2020

Sealing My Flat Roof Attic

A very tight space with no access. Several companies said it could not be done, but Energy Monster got in there and completed the job. I never give 5 stars, as they don't exist, but in this case it did. Well done. Robert in St Pete Beach, FL.

Dennis | 03/02/2020

Terrific Value!

Everyone starting with Orlando Rodriguez the initial salesman, to Kyle Johnson my program manager to the installation crew, to the electricians were extremely professional, responsive and quality oriented. I loved the fact that there is a 20 year, transferable warranty and they will stay involved the whole time. They helped me get the rebates and made the system very affordable. 5 stars is well deserved!

RadCat | MA | 02/21/2020

Professional

They are very professional and courteous. Any questions we had were answered with a lot of knowledge. I look forward to the savings of the solar panels.

hannah1787 | Lancaster, MA | 02/07/2020

Organized, professional, helpful

We chose them because their prices were good, they were responsive to questions, and we felt that the panels they were offering, specifically the inverters, were the right option for us.

Dee | 01/18/2020

efficient units, efficient company

Energy Monster walked me through the process and made things easy. There was little paperwork and the communication was stellar. My units are now in and I am looking forward to the savings I will now enjoy since I retired my old oil furnace

RayFay | Hadley, MA | 01/17/2020

Great Company-professional and quality service

Thank you Energy Monster! Your company has a staff that is prompt, courteous and very easy to deal with. We appreciate dealing with people who are quick to respond to questions and make every effort to serve their customers. Estimates, communications and installation were all handled professionally-very nice work.

union bridge Rd | DUXBURY, MA | 01/16/2020

great people and good prompt service

My niece recommended them to me and I was very happy with the service. Some confusion when the wrong panels showed up, but it was taken care of with no question.

Lin | Shirley, MA | 01/06/2020

Will recommend the service to my friends!

A friend of mine recommended the Energy Monster. I am very happy about the service! I will certainly recommend the service to my friends!

A Palkar | Hopkinton , MA | 12/24/2019

Fantastic service

Best solar company in central mass, very professional, responsive with reasonable price

Vinny P. | Fitzwilliam, NH | 12/21/2019

Very Satisfied!

Had my solar system installed back in March 2019 (30 LG Panels)... After researching many reviews, cost & sitting w/ a few sales people from different solar companies, Energy Monster was clearly my choice. Orlando & Dan were very helpful answering any questions I had regarding the system... The installation crew of 4 were very professional, they completed the job in two days & the work done was very neat... I have a new home and am a nit picky person that's hard to please when it comes to neatness & appearance of any work done for me... All I can say is I couldn't be happier with the team, their installation and performance of the system, I highly recommend Energy Monster, Thank You Orlando & Dan! Vinny seivad1(removed for privacy)

Matt M | Westford, MA | 12/21/2019

Great Everything!

Worked around my scheduled and preferences. Easily understood what was important to me and didn't try to sell me something I didn't want. Didn't force me to meet with them in person before giving me numbers, very easy to work with. The crew that installed everything was quick, and did a great job of hiding the wiring from the box to the roof panels. Unlike some other companies, who had crazy unrealistic projections I couldn't trust, Energy Monster had ones I could trust. Having the system for about 6 months, the panels have actually been more efficient than they claimed. Generation over the 6 months is great, way better than projected. Everything about them was great, I even had a paperwork issues with some rebates and they kept helping making sure it was all setup properly with the state! I could not recommend them more.

Howard M | 12/14/2019

Outstanding Service

They proposed the best system to meet our current and future needs.

Matty c | Dracut, MA | 10/19/2019

Very impressed

I just finished the Solar install with energy monster. 31 panels. I am a very talented Picky jack of all trades individual that can do about everything. I am highly impressed bye the crew of energy monster. The install is flawless! They hit every roof hoist without a single miss I checked the entire roof line inside that attic. There wiring and electrical box placement was perfect and neat! Four guys came and you can tel the have been working together for along time. I completely trusted these guys and even left my home unlocked for them on the second day. All paperwork was taken care of even the loan process was extremely easy! If you would like to contact me or take a ride bye feel free. Mattyco63@gmail.com

Kaz | Holland, MA | 09/16/2019

Professional and Great Service

Received three quotes from solar companies, and Energy Monster, by far had the best quote.I was amazed by the professionalism Dan and his team showed during the whole process, from the beginning to the end. They answered every question and concern I had at anytime of the day. The whole crew was a pleasure to work with, and know their stuff. I am so glad I chose Energy Monster as my solar panel company. I highly recommend anyone thinking about going solar to give them a call.You will not be disappointed! Thank you again Dan and team.

Jay Sun | Ware, MA | 08/27/2019

Professional and timeline was accurate

They quoted me for the most panels to handle my present and future needs and it wasn’t much more expensive. All other companies quoted me on 8 to 14 panels less with comparable prices.

T. Kane | West Springfield , MA | 08/23/2019

Great customer Service!

From beginning to end the company was great. No high pressure sales pitch and price was way better than others for equal or better equipment. Every step of way workings were very quick to answer any questions and made process very simple. I’d highly recommend this company
