32 M AY / J U N E 2 0 1 8 A s we have continued our expansion in the commercial and industrial solar market (which includes commercial, indus- trial, municipal, university, school, cold storage, food-pro- cessing and hospital buildings), we've discovered something. If commercial building owners are not overly familiar with how solar arrays are installed, they have legitimate concerns about the poten- tial effects solar arrays could have on their roofs. For example: Will the racking system, which holds the solar modules in place, harm the roof? Will it have to be penetrated, creating potential pathways for the elements to enter? Will it shorten the longevity of the roof? Will it void the warranty? In addition, we've discovered it's often not just solar that these building owners want. They are often looking for energy-efficiency measures, too, particularly as property assessed clean energy (PACE) programs allow them to pay for both kinds of upgrades through their property taxes. At Standard Solar, we take those concerns and desires seriously, and we've been searching for an all-encompassing solution — and we believe we have found one in spray polyurethane foam (SPF). SPF acts not only as an additional barrier to the elements, but it is also incredibly insulative. As a result, building owners who use SPF as an underlayment to their current roofing will reduce energy consumption and save money on their energy bills. Let's take a closer look at how SPF works and how it will help you reach your solar and energy efficiencies goals. Longevity match One of the strongest arguments for installing a rooftop solar array on a commercial building is to provide electricity for the building for at least 25 years. Many roofing materials can't match that lifespan, but SPF can — and reduce energy bills by 20 to 50 percent more than fiberglass insulation in the process. When the proper roofing material is wedded to a rooftop solar array, the building owner can stop worrying about either. Instead, they can spend their time counting the savings the electrical system and energy-efficient roof will provide them.
