I waited 3 months to write this review, to ensure that I really had a chance to test RES solar's system thoroughly (also, i never leave reviews). My family moved to MA from NC, where it's much warmer. Needless to say, the first summer here was disappointing. Our pool barely got to 72-75 (and only for a couple days). We maybe got in the pool a dozen times the entire summer. This year, I contacted Erica to install several panels in hopes that the pool would be warm enough for us to use consistently. I was very skeptical, but unless I was ready to pay for gas heating, I had no choice.

RES installed a solar heating system for our backyard pool. They were incredibly professional, easy to work with, and available as needed after installation. This is one of the best investments we've ever made, as the system will pay for itself within 5-6 years (we're on year 2). We're only using 1 tank of propane a season now (vs. 6-10 tanks in past summers) - just for the very beginning of the season to supplement solar. Best thing about the system (vs. propane heat) is it's "set it and forget it". We just set the target temp and the solar turns itself on and off as needed. It also replaces the

If you were looking for an alternative and green way to heat your home, shop with RES. You cant find better work to be found on the south shore.

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
