New solar product 'beats the heat'

By Carmen Bellavia, president and CEO, 3 IN 1 ROOF

Historically, solar panels have been the most efficient way to generate energy on high-sloped roofs. Black or blue silicone solar cell have average efficiency ratings of around 22 out of 100 percent. Once solar cells are grouped, placed under glass, fitted with a polyurethane backsheet (a solar panel) and mounted over a traditional shingle, tile or aluminum roof, their efficiency rating falls TO between 15-17 percent.

While a few solar panel manufacturers claim ratings higher than 20 percent, buyers should be aware that those figures are gathered when solar panels are installed in optimum environments, such as on solar farms or SPF roof systems.

Our company, 3 IN 1 ROOF, has invested in a technology and resulting product that surpasses the vaunted efficiency of standard solar panels by surrounding the cells with heat-dispensing material that improves their performance long after peak solar-collection times.

During morning and afternoon hours, the 3 IN 1 ROOF system is as efficient as solar panels when panels are installed over previously mentioned traditional roofing, according to our tests. The difference after 3 p.m., however, is dramatic. On a typical 88-90 degree day, our system acquires about 23 percent more energy compared to traditional panels. The reason is heat.

By late afternoon, traditional roofing has collected and amassed so much heat from the sun, they reach surface temperatures well over 150 degrees. For every 20 degrees the surface temperature of a traditional roof rises above 120 degrees, the solar functionality decreases by 5 percent. Therefore when common roof products are at their hottest, a solar panel’s efficiency is at its lowest. Plus, as everyone knows, asphalt, concrete and metal takes many hours to heat up, and in turn takes the same amount of time to cool down or even longer if the attic is poorly ventilated.

The 3 IN 1 ROOF system is different. Using two amalgamates, the 3 IN 1 ROOF is composed of heat-resistant closed cell foam and is coated with a durable geopolymer that increases in temperature only about 12 degrees above ambient.

As the ambient temperature rises and falls, so does the surface temperature of the 3 IN 1 ROOF and at near simultaneous frequencies. Therefore unless summer temperatures excede 110 degrees Fahrenheit, the 3 IN 1 ROOF system’s solar module will always yield maximum efficiency. In addition, its SPF-like foam character blocks all solar gains from entering into the attic area, lending day-long cool substrates, decking and garrets, virtually eliminating heat flowback.

When one takes into account around 4-5 hours of advanced power creation, it mathematically boosts the 3 IN 1 ROOF system’s overall efficiency rating to 17-19 percent, making it the world’s highest and best performing integrated solar product, if not arguably the most efficient solar system installed on a high-sloped roof so far.

Heat flowback and why to eliminate it

Solar gains into an attic cause humidity issues fundamentally negative to any structure, including but not limited to dry-rot, condensation, mold and everything that’s related to moisture plus heat. Flowback is when attics get so hot, they’re virtually structural incubators. Hot air prevents the wood decking it contacts from cooling down while the traditional roofing cools over night, thus prolonging the roof’s ability to equalize ambient temperature.

All these dilemmas are not only problematic with traditional roofing systems, they’re also drawbacks for each and every integrated solar tile and integrated solar shingles systems that is or was available for purchase before the launch of the 3 IN 1 ROOF system.
