Looking at Solar PV Roofing

Generating part or all of a facility’s electricity with photovoltaic (PV) systems is growing in popularity all over Florida. Whether the systems are used to lower peak demand costs, power an individual facility or enhance the green aspects of a project, even the smallest systems can help lower electric bills and clean up the environment.

Of course, up front cost remains an issue. Many states, such as Florida, offer a range of incentive programs, many of which could take a PV system from the red to the black in just a few years. And as utility rates increase, payback periods shrink.

A Nod To The Newest PV System
For those of you whose idea of a PV system dates back to the ‘70s- glossy blue tinted panels fastened to metal racks bolted to a roof- take note: new products are available that integrate PVs into the building, making them not only less obvious but also less risky.

There are many concerns about what type of PV system is best. Obviously, cost is a major issue, despite generous state and utility rebates. The system also needs to fit the design and maintenance needs of the facility. Many owners are not interested in poking holes in a perfectly good roof. This is the reason many organizations are now looking at thin-film flexible membranes.

Thin-film photovoltaics do not have a rigid frame or solar cells. Instead, the material that generates electricity is layered onto a rubber like substance. It’s as flexible as a roll of roofing material and we install it onto the roof much the same. It attaches directly to the roof surface with adhesives so there are no roof penetrations. In fact, the system really can’t be seen unless you are actually on the roof. Even better, they are more efficient under diffuse light than typical, rigid polycrystalline modules, something worth considering. These flex panels are tough stuff. To test their durability, the team at RAMCON has walked on them, stomped on them and even whacked them with a hammer. They continued to produce electricity as specified.

RAMCON is among the very few contractors in the industry with experience in photovoltaic systems, having installed more than 37 kilowatts. For more information or to determine the costs and estimated pay back periods for a system on your facility, give us a call at (877) 726-2661.
