Hard Panel Solar Systems
Hard panel solar systems are a great choice for commercial buildings or institutional facilities with a limited roof area or for ground mount solar systems, when the roof area is either not available or is not viable for a solar array. As an experienced commercial solar installer, Pfister Energy will assess your site to see which type of solar installation - roof mount or ground mount - is best suited for your property.
Hard Panel Solar Modules
Hard panel solar modules can withstand high winds, sleet, hail and other extremes in weather. They also are able to maintain a tilt angle, when needed, so that rain and other weather can easily run off the panels, making the system nearly maintenance free. Hard panels are installed on a ballasted racking system, which can be removed in order to make any necessary roof repairs. There are two types of hard panels: monocrystalline and polycrystalline. Monocrystalline panels have have the highest output per area. If space is a concern, monocrystalline will be the best type to use, and more wattage per square foot can be delivered with these panels. Polycrystalline modules are less efficient than those made from a single crystal; however, they are much simpler to produce, and cost less to manufacture.
Mounting Systems: Roof or Ground
Roof mounts are a popular and durable solar energy solution. They can be installed on most roof styles and materials, including metals. However, they can add as much as 8 to 10 lbs. per square foot to a roof. Therefore, the roof must be able to withstand this weight, in addition to brackets and mounting hardware. Ground mounts are typically large-scale solar systems, installed in areas away from the city electric grid. This mount is a great solution for landowners to maximize efficiency and electric output. Your property must have enough land for a ground mounted solar system, and you may need to check city or county ordinances before installation.
