Success Stories

Renewable Energy Systems (RES) LLC designed and installed a Solar Hot Water system at the University of Massachusetts Lowell campus. The system provides hot water to the Inn and Conference Center. RES performed this work on a design-build basis. They completed all the required work in a professional and timely manner. RES continues to be thorough in their follow-up and verification of savings.

I would not hesitate to use RES on future Constellation Energy projects or to recommend others utilize RES for a solar thermal project.

Solar Pool Heating

Commercial solar pool heating is another option to utilize renewable energy on your property. Solar pool heating is a simple and inexpensive way to keep commercial pools warm from May into September without the use of expensive gas or propane heaters.

RES can complete a comprehensive site evaluation. In most cases the systems can utilize the current pool pump, reducing cost and maintenance. Solar pool heating systems can either be roof or ground mounted.
