Enclosures for solar applications

Enclosures for the Solar Industry

SolarSolar pannels power is the conversion of energy from sunlight into electricity, either directly using photovoltaics, indirectly using concentrated solar power, or a combination. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam

While the panels and inverters get all the attention and look great in a photo,  the control systems are just as important and can cost as much as the panels and deserve equal attention.  After all if these solar Balance of Systems (BOS) electrical components are not protected from the elements, then the solar project won’t work, or will not work efficiently.


Keeping up with the demand for solar power

As the cost of solar panels decreases while their effectiveness increases more and more people, companies and countries are migrating to solar power.   Non-conductive Fibox products are perfect for solar applications, and we understand that one size does not fit all.  Your design will need to  weather the elements out of doors and operate in the most extreme environments and offer a long service lifetime to your clients.  Fibox enclosures are UL listed and rated NEMA 4X protecting your equipment while making service and inspection simple and hassle free. Some of the common uses for our solutions include;

How polycarbonate enclosures fit in the solar industry

From start to finish, Fibox is the there enclosing your innovations.


  • Solar Power Inverter
  • Combiner Boxes
  • DC Disconnect Boxes
  • Solar Tracking Systems
  • Controls Systems and Switchboards


When deciding what enclosure to utilize for the various BOS components in a solar power project, you must consider many environmental factors including;

  • UV Exposure
  • Temperature
  • Humidity

Fibox NEMA 4X non-metallic polycarbonate weatherproof enclosures offer the best of all worlds. UL listed NEMA 4X & 6P provide a dry and dust free environment in even the harshest locations, thanks to the formed in place PUR gasketing.

Fibox’s non-conductive, rust-free, thermal-set plastic has a much higher impact resistance than metal or fiberglass. Only Fibox polycarbonate can give you such unparalleled UV protection, tested to withstand 5,000 hours in an accelerated aging test without blooming like fiberglass. Our radio transparent plastic is ideal for remote solar applications and eliminates the need for an external antenna. Lastly polycarbonate is exceptionally lightweight, easy to transport and modify and handles cold and blazing heat.

UV is not a problem for a Fibox


When protecting your design in either a large scale solar power plant to a small residential solar power system Fibox Enclosure offers the best box under the sun!
