McElroy Metal Solar Solutions combine metal roofing with crystalline and thin-film solar technologies. The end-result is a functional and environmentally friendly roof system that generates renewable, clean, green energy.

Photovoltaics (PV) are products that convert sunlight into electricity. They are commonly referred to as solar cells. PVs are made of semiconductor
materials such as silicon. Cells of PV material are put together to form a module, and modules can be grouped together on roofs to form arrays which generate power to the building. Crystalline systems consist of an array of silicon wafers sandwiched between two layers of glass. These panels can be heavy and must be attached to a roof using S-5! clamps or bracing. 

Characteristics of Crystalline 

  • More popular
  • Widely recognized as “conventional” solar panel
  • Generates more energy per square foot

Thin-film PV systems are flexible, lightweight and adhere directly to the pan of a metal standing seam roof. In that case, the PV system is actually integrated into the building design and is almost unnoticeable on the roof. Metal roofing provides the best platform for the building integrated photovoltaic (BIPV) system. 

McElroy Metal is a proud supplier of Miasole Flex Series PV Module. The FLEX-02 Series module is a CIGS based flexible thin-film PV module that provides high power density for many types of roof applications. The panels are the highest efficiency, flexible, thin-film product on the market today, with >16% cell efficiency.

The FLEX-02N module is 14.6 inches x 102.3 inches and is rated at 120-watts, and designed specifically for standing-seam metal roofs. The FLEX-02N module bonds to the roof surface with a simple peel-and-stick adhesive. Visit Miasole’s website for more information at

Characteristics of Thin Film

  • Light weight
  • Flexible
  • Aesthetically pleasing
  • Factory or job site installation
  • Works well in cloudy conditions

Solar Panel Kits

Your McElroy Metal Representative markets complete solar kits for both Thin-Film Solar and crystalline solar systems. By simply providing roof square footage and roofing type, your McElroy Representative can provide pre-engineered complete photovoltaic kits that include solar panels, inverters, cables, fuses, disconnects, and all other accessories to create your custom solar system.

Local, State and Federal Governments encourage the use of solar and many incentives are available for individuals and companies that install Photovoltaic systems on their homes or businesses. For information about available federal, state and local incentives for solar visit:
