SolarWorld ups product workmanship warranty for solar panels to 20 years

Move sets new standard for PERC (passivated emitter rear contact) solar panels

HILLSBORO, Ore., Feb. 3, 2017 - SolarWorld, the largest U.S. crystalline silicon solar panel manufacturer for more than 40 years, announced today that it has doubled the duration of its workmanship warranty on its entire portfolio of solar panel products to 20 years. With the improvement in consumer protection, the company becomes the first major producer of solar panels featuring the popular, high-power PERC (passivated emitter rear contact) solar cell architecture to offer a product warranty of that length.


The extended product warranty, which protects owners of SolarWorld solar panels against defects attributable to production flaws, applies to all solar modules shipped after Jan. 1, 2017.

The extension comes on the 20th anniversary year of SolarWorld's 1997 establishment of the industry's first 25-year performance guarantee, which declined from 90 percent of nameplate power to 80 percent at 10 years. In 2009, the company was first to offer a 25-year linear guarantee, which provided better protection because the percentage of output protection declines by no more than .7 percentage points each year after the first year. In 2013, SolarWorld's Sunmodule Protect solar panel, which features glass on front and back, was introduced with a 30-year linear guarantee, with annual degradation of no more than .35 percentage points.

"Over the decades, we have been able to take the lead in our product protections because we have the track record - the real-life data - to give us confidence in our products," said Shane Messer, U.S. vice president for sales and marketing for SolarWorld. "At every stage in production, we put quality first, and the investment has paid off over time.

"Consumers win because they can count on more protection for their own investment," Messer said.

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
