Go Power solar panels powering ClimaCab system at MATS

March 26, 2014

LOUISVILLE. Go Power! has announced that its Solar Flex panels will be displayed powering  Cummins Crosspoint ClimaCab cab-comfort systems this week at the Mid-America Trucking Show.

A Solar Flex-powered system is being used to show how solar power alone can keep dedicated batteries in their battery-powered cab-comfort systems fully charged and ready to start equipment, Go Power! said.

The thin, flexible, ultra-high-efficiency Solar Flex GP-Flex series panels were originally developed for the RV industry, where a/c power loads and HVAC climate control demands are similar to those of a small cottage. The Solar Flex panels were designed to contour to the roof of an RV and to allow the vehicle to operate completely autonomously for weeks at a time, with no need to connect to Shorepower or any other supplemental power resource, the company explained. 

“By focusing on fully solar-powering RVs, we tackled and solved the hardest problem first,” Sean O’Connor, sales channel manager for Go Power! North America, said. “I can’t imagine a sleeper cab with a power demand that would even approach what our Solar Flex technology has been able to deliver to full-time RVers.”

The Solar Flex system has the ability to produce about 100 watts-per-foot of trailer length. A 53-ft. trailer has the roof area to hold approximately fifty 100-watt Solar Flex panels and to generate about 5,000 watts, or about 280 amps, of DC power per hour. When combined with a Go Power! inverter, a system can produce up to 3,000 watts of AC power per hour.

Cummins Crosspoint was looking for a reliable solar-based method for keeping the dedicated batteries used in Carrier Transicold refrigeration units and ClimaCab battery-powered cab-comfort systems optimally charged, Go Power!. Under normal circumstances, parasitic current draw can drain reefer and APU batteries whenever their dependant engines are not in service.

“We have been looking for a practical solar solution for battery regeneration for a while, but the rigid-panel systems we found couldn’t stand up to the shock, vibration and debris strikes that vehicles commonly encounter; plus, they were heavy and bulky,” Joe Aschenbener, general manager for Crosspoint Power & Refrigeration, said. “The light, thin Solar Flex system is bendable, can mount almost anywhere and is so durable, you can drive over it without significantly damaging it.”

Aschenbener noted that the built-in telematics in many reefer units can completely drain their starter battery within just four days of sitting idle and that the downtime and service cost of jumping a dead battery can really add up.

“In the case of our ClimaCab battery-powered cab-comfort systems, it’s critical that optimal charge is maintained at all times,” Aschenbener said. “The trickle charge generated by the new Solar Flex system assures us that reefer and batteries are always at the ready, regardless of the inactivity of the vehicle.”

Solar Flex panels can be safely secured to the cab and trailer roofs with adhesives, eliminating the need to penetrate watertight surfaces with fasteners. At just 3 millimeters thick, the thin panels can flex to follow rooflines and are simple to install, presenting virtually no height restriction issues in the process.

 The Solar Flex panels are coated with a marine-grade laminate and can be secured adhesively to metal, rubber, fiberglass and plastic surfaces. The panels also can be secured with fasteners through precut eyelets and can flex with parabolic bends of as much as 30 degrees. The panels are extremely durable and can even stand up to foot traffic.

 The Solar Flex panels come in 30-, 100- and 200-watt power kits and can be paired with a wide range of Go Power! inverters for a complete system.
