Flexible solar modules used for refrigerated vehicles

"The application of flexible solar modules in commercial vehicles shows that our standard products for BIPV are suited for other applications as well," said Dr. Karsten Otte, CEO of Solarion. "We are confident that such innovations in the field of emission and noise reduced logistics and the electrical mobility will have a bright future."

The 30 CIGS solar modules (thin film solar modules using Copper-Indium-Gallium-

Diselenide) used have an efficiency of ten percent and can deliver a peak power of three kilowatts, explained the company. It added that with their use about 1,000 liters of diesel fuel can be saved annually, equivalent to a reduction in carbon dioxide emissions of 2.5 metric tons.

For this study the entire roof of a trailer was covered with flexible solar modules. The company said the generated electrical energy can be used to support operation of the refrigerating unit Carrier Vector 1550. This reportedly saves fuel costs, decreases carbon dioxide emissions and reduces the noise level of the refrigerating system.

The concept was developed in close cooperation between Krone, Carrier and Solarion. The goal within the next two years, said the companies, is to develop a system that pays for the customer.
