Here’s where UV stabilized fasteners truly shine. Designed with a mounting base or a cable tie buckle, these products will last ve to seven times longer than a UV rated cable
tie through a module mounting hole. Parts made from UV stabilized plastic, along with other modi ers, can drastically increase the life expectancy of these products in the elements.
In fact, some plastic compounds
can last even longer, around 15 to 25 years. Choosing engineered plastics designed to perform in the elements will consistently deliver rewards.

Lastly, come up with a sound O&M strategy. Consider the combiner box M
shown above. e wire entry was sealed with a compound, but one
that was not rated for outdoor use.
As the compound aked away, water seeped into the conduit and owed CY down to the combiner box. A more CMY routine maintenance schedule could K have caught this issue before leading to expensive xes. Unfortunately, in this case, a complete combiner box replacement was required.
Focus on these three steps to successfully master solar installation costs and risks. E ective wire management can help save money at installation, reduce installation times and maintenance visits, and continue delivering over the long term.

Fully integrated mounting and racking solution
Quick Mount PV introduces the QRail rooftop racking system, a comprehensive, cost-e ective single-source solution for solar installation on all roof types. Combined with the company’s waterproof mounts, Quick Mount PV now o ers a complete, fully integrated racking and mounting solution for installing solar PV modules on any roof. QRail features patented QClick and QSplice technologies to streamline the installation process. Mid- and end-clamps with QClick technology simply snap into place and remain in an upright position, ready to accept the module. QRail’s QSplice is
a tool free, bonded structural splice that installs in seconds with no tools or extra hardware required. External splices are also available. QRail is designed and engineered for strength and versatility. e aluminum rails come in three sizes, Heavy, Standard and Light and are available in 168" and 208" lengths, in mill and black nishes. e QRail Series is compatible with virtually all PV modules and L-foot attachments. Modules can be mounted in portrait or landscape, in either standard or shared rail con gurations.
QRail also comes with QDesign, a free online design tool to enable quick and easy design of solar arrays, as well as produce detailed bills of
material and all necessary engineering reports.

Adding energy storage to a new or existing utility-scale s-olar installation with a Dynapower DC-DC converter can increase PV energy production through clipping recapture and low voltage harvest. Further adding to your bottom line, DC-coupled solar plus storage has a higher efficiency t-han AC-coupled storage and is eligible for valuable tax incentives for installation owners.
To learn more about how Dynapower’s patent-pending line of DC-DC converters can increase project revenues and lower the installation costs of utility-scale solar plus storage, please visit our website to download the
