Meets strict quality standards
These panels are manufactured in state-of-the-art German factories and meet strict environmental and quality standards. All SolarWorld panels are produced using plus-sorting which guarantees every module will deliver an efficiency greater than or equal to its nameplate rating.

Designed for maximum power output.
The SW 315-watt Pro XL module is manufactured with a silver aluminum frame and 72 monocrystalline solar cells. These panels generate more power per panel than most other panels on the market. For the DIY installer that means installing less panels on your roof, or the ability to generate more power with limited roof space.

Longest warranty in the industry
The linear warranty guarantees power generated will not decrease more than 0.7% per year from its nameplate. This guarantees that each module will produce at least 83.89% of its nameplate power after 25 years! On top of this SolarWorld offers a 20-year product warranty.

About SolarWorld

The leader in American solar manufacturing: As the largest U.S. solar photovoltaic manufacturer for more than 40 years, SolarWorld is uniquely recognized as America’s solar leader. Solarworld has been producing modules here in the U.S. since 1975 and maintains a continuous commitment to quality and manufacturing excellence.

Not only does Solarworld employ hundreds of Americans at their facility in Oregon, they also help stimulate the U.S. economy by sourcing domestically whenever possible. Since 2008, SolarWorld purchased more than $1.5 billion in equipment, parts, services and supplies from 50 states, plus the District of Columbia and Puerto Rico. This creates even more American jobs and supports American businesses.

A Higher Standard of Quality: Solar panels produced at SolarWorld manufacturing plants have operated in the field for the past 40-plus years, making them the longest continuously running commercial solar manufacturer. SolarWorld has a proven track record of outlasting and outperforming their warranties. This is accomplished by carefully controlling and precisely executing every step in the manufacturing process.

Here are a few ways SolarWorld emphasizes their commitment to quality:

  • Extreme solar panel testing
  • Rigorous top quality material selection
  • Inspection and trace-ability
  • Superior junction box
  • Fully automated manufacturing
  • Third-party validation
  • Constantly innovating

Committed to Sustainability

SolarWorld’s commitment to sustainability and community involvement is demonstrated by their many programs aimed at reducing waste, conserving water, recycling, and responsibly sourcing materials. Through their Solar2World initiative, the company donates solar panels to power community services around the world such as hospitals and water pumping.
