DUNMORE Corporation has developed a new version of its DUN-SOLAR TPE solar module backsheet. TPE provides the proven performance of DuPont ‘Tedlar’ polyvinyl fluoride film in a construction that exceeds current market requirements for longevity and total cost of ownership.
With warranty periods on solar modules extending to 25 years and beyond, manufacturers are seeking high-performance components that won't cause premature failure or performance loss. At the same time, they need to keep their costs low so solar energy can compete with the price of established energy sources.
The new TPE backsheet made with improved materials extends solar module lifetime and productivity because they better protect the solar module's circuitry from moisture and performance loss. More durable insulation also protects workers from electrical shocks while they are maintaining solar modules. DUNMORE engineered this advanced backsheet using the latest Tedlar oriented polyvinyl fluoride film, improved polyester core and adhesive materials. Now DUN-SOLAR TPE offers damp heat performance beyond 3000 hours at more competitive pricing.
PV module backsheet integration via the lamination process.
DUN-SOLAR TPE is among the first UL-listed backsheet that incorporates the latest Tedlar oriented polyvinyl fluoride film. PV manufacturers looking to start using the the next generation TPE can take advantage of DUNMORE’s ‘SmoothStart’ engineering services program. The SmoothStart program places one of the company's engineers on the customer's production floor at no additional cost.
Will be in full production starting in Q3 2012.
