PhotoVoltaic Solar Systems

PhotoVoltaic (PV) Solar Panels are designed to produce electricity from exposure to the sun’s radiant energy. This electricity is considered “free” electricity since no fuels are used to produce it.

The mechanism is fairly simple. Silicon wafer semiconductors are exposed to the radiant energy of the sun and produce a small electrical current. To make enough power to matter, groups of these semiconductors are connected together in a panel. These panels are arranged in arrays so that the wattage produced is then transferred to a power inverter that converts the direct current produced by the panels into more usable alternating current to run appliances, etc

Until recently, these PV panels were composed of large, bulky, glass-enclosed panels that created holes in the roof where they were mounted, requiring a host of flashing details that the PV installer was ill-equipped to address.

The new generation of PV panels are laminated to flexible panels of polymeric membrane at a much reduced cost and reduce the number of roof penetrations since they need no special mounting racks that penetrate the roof. Instead, the flexible laminated PV film panels are adhered directly to a compatible roofing membrane conforming to the roof membrane’s contours.

Benefits of Film-laminated PV Panels

  • Minimizes roof penetrations for installation
  • Effective without having to be angled directly to the sun
  • Increased security and wind resistance due to fusing films directly to the roof membrane
  • Lighter weight than glass panels adding very little additional load to the structure
  • Lower cost to manufacturer
  • Higher electrical conversion efficiency
  • This technology is also available in the form of smaller roof tiles that can be used in residential applications, taking the place of conventional roof tiles or shingles.
  • Fact: Federal Tax incentive: 30% Investment tax credit on installed system cost. Other regional power companies may offer rebates for PV systems as well.
