DPW Solar Debuts New Ballasted Flat Roof Mounting System

DPW Solar is proud to debut the new POWER XPRESS Ballasted Flat Roof Mounting System, designed to help installers mount solar modules faster and easier.  Installers of PV solar modules can spend hours aligning mounting racks in perfect rows while wrenching their necks and raking their knuckles to tighten hard-to-reach clamps. Now they can do the same job in a fraction of the time at a fraction of the cost with none of the discomfort, thanks to the new POWER XPRESS Ballasted Flat-Roof Mounting System.

From DPW Solar, an early pioneer of solar module mounting systems, POWER XPRESS is one of the simplest flat-roof systems to assemble. It has only two main components, a chassis and a clamp, which makes it easier to transport and quicker to set up.

The smarter design also makes POWER XPRESS cost less than other top-quality, flat-roof racking systems.

You can see the POWER XPRESS at Solar Power International (booth No. 858).

“POWER XPRESS is the third generation of our field-proven ballasted, flat-roof racking system,” says John Markiewicz, General Manager of DPW Solar. “It’s more modular than any of the other systems we’ve introduced during our 20-plus years in the PV solar industry. That makes it easier to customize to the roof and about 30 percent faster to lay out and assemble.”

Install POWER XPRESS in four simple steps

Lay out chassis on the roof. Use spanners and jigs to align them.
Place cement blocks in ballast pans.
Lay down solar modules.
Secure modules with clamps, tightening the bolt outside each chassis.

What’s better about POWER XPRESS?

Lower cost. Because of the smart design — using fewer parts and less material — POWER XPRESS costs less than many other ballasted, flat-roof mounting systems.
More modular. Lay out solar modules in various configurations to fit the roof. You’re not restricted by rails or subassemblies, as in conventional designs.
Quick to assemble. No more loose hardware to keep track of as POWER XPRESS uses only two main components: a chassis and a clamp.
Full-containment ballast pans. When concrete blocks weather and break, their pieces stay in the pan and continue serving as ballast weight.
Hassle-free clamps. Instead of clamping down on top of the solar module or through bolts underneath, POWER XPRESS clamps latch to the lip on the module’s underside. Tightening each clamp is hassle-free because the bolt is easily accessible outside the module frame and chassis.   In addition, the POWER EXPRESS clamps fit almost all solar module designs.
Built-in electrical grounding. No need to add extra grounding components. Once the solar module is clamped, it’s grounded thanks to the clamp’s penetrating teeth.
Optional wind deflectors. They’re easy to snap in if you need them. But if you don’t, they’re not built into the standard design, keeping your system’s cost down.
