Commercial Solar/ Seal Program

Commercial Rooftop Solar - 508 746 5430

After fifteen years of installing commercial solar energy we find that older rooftops of metal, rubber , or TPO often need to be seale d before the solar panels are placed . As we ins tall solar with 25 and 30 - year warranties w e need to be confident that the roof surface under the array will maintain integrity for the life of the system.

The Issue

After several early roof - coating projects we found that materials used by roofers and the quality of craftsman ship varied from excellent to - 'I wish we didn't do it'.

The Answer

To gain control of both material and craftsmanship, Plymouth Solar embarked on researching best practices for labor, along with detailed analysis of coating materials . Understanding that energy output from solar is influenced by temperature and albedo (a measurement of reflected irradiance ) we specify coatings that not only seal the roof, but also have reflective and thermal characteristics that enhance the energy output of the solar.

The Process

Today, Plymouth Solar Energy teams with roofing specialist s who first clean the roof, and repair any areas of concern. Solar panel attachments are then installed according to the solar design, and then we coat the roof, sealing the roof and the new attachments under a seamless monolithic membrane.

Benefits of the Solar/Seal Program

By coating the roof with materials that offer reflective and thermal attributes while embedding the solar attachments under the coating, positions the entire project as a single 'capital investment,' rather than roof repair and then solar install. As a single capital investment, the system qualifies as a section 179 investment. Under 179, owners can take 100% depreciation the first year, as well as the 26% investment tax credit for the entire project.

More Details

We apply the solar coating to the area that solar panels will cover, plus 20%. The additional 20% area establishes a coated perimeter around the solar so if the owner wants to do the entire roof in the future, there would be no need to remove the solar panels .
