My experience with RES Solar was fantastic. Erica and her team are professional, experienced and friendlyRES removed and reinstalled my hot water solar panels that heat my pool walking me through and improved my system I have after recently purchasing a new homeI highly recommend RES Solar
This is by far one of the best companies I’ve ever worked with, for anything. From start to finish, their expertise, patience, and customer service have been impeccable. They installed a pool solar heating system on the roof of our house, the installation went flawlessly. Their customer service after the installation has been just as good, helping us to troubleshoot any issues. I would highly recommend them.
We replaced an old Solar hot water system with a new efficient one several years ago. This new system was installed by RES solar. The installation team was excellent and followed up with any adjustments required. It has saved us a significant amount of money by preheating the hot water for the house.Recently, we had to have the roof replaced. Coordinating the temporary removing our solar heating panels with the roofers was a potential challenge . RES solar arranged removal quickly so that the roof could be replaced on time. The re-installation of the solar panels and testing the system was also quickly done after the new roof was completed. I could not have asked for better service from RES Solar.In addition, the installers spent time explaining in great detail how to monitor the panels so I can check temperatures in the column as well as in the tank . This now allows me to really keep track of of the system and any potential problems. I really appreciated all their effort and patience. I would highly recommend the RES Solar company for any type of solar panel installation and maintenance.Jack Richman
We are ecstatic that we found RES Solar to install a heating system for our pool. The previous owners installed a pool in a heavily shaded area and it was always very cold (we moved into the house in 2014). This spring, Res Solar installed their heating system onto the southern facing side of our garage and the results were fantastic. The temps in our pool were between 8 and 15 degrees warmer than any season in the past 8 years. Erica and Matt were very responsive to all questions and made the process super easy. We also live in metrowest MA and they traveled the distance to do the job.
The Nantucket Hotel was in need of a solar solution to mitigate the high cost of propane on Nantucket and Matt and Erica came up with a great solution for our historic property (1891) located in the highly controlled downtown district. They took care of getting HDC approvals, designed the system to fit our neighbors and helped us maximize the financial incentives.During the planning, installing and after the installation, they have been great communicators and easy to contact.I highly recommend giving them a chance to do the same for you. Technically they were great, but the customer care quotient was even more important.
