Solar4America is promoting American products and reinvesting in American manufacturing. A solar energy investment should be something you can rely on and it is imperative to have top quality solar panels, produced by reputable manufacturers that will be around.

PetersenDean is proud to partner with American solar panel manufacturer SolarWorld and inverter manufacturer Kaco. Both our solar partners are based in the United States, supporting American manufacturing and the American economic recovery. We are honored to offer fully American solar power installation options to our customers.

SolarWorld solar panels are widely recognized as the industry standard in quality-the result of the company’s commitment to research and development, superior materials and manufacturing excellence.

SolarWorld solar technologies are different because the company is different. Every step of the manufacturing process is meticulously controlled and sustainably executed to ensure maximum energy output from every panel.

High-quality solar panels begin with high-quality materials. SolarWorld is so selective that it manufactures every solar cell it uses-right here on American soil. Each cell is carefully inspected for possible damage, tested for efficiency, and classified according to color and power levels. SolarWorld solar panels are independently certified by a multitude of agencies and organizations, and backed by the first 25-year linear performance warranty offered by the industry as well as a 10-year product workmanship guarantee.

"SolarWorld has manufactured the highest quality, American-made solar panels for U.S. homes and businesses for more than 35 years. From our factory in Hillsboro, Ore., our American workforce delivers technology, performance, service and an environmental track record that lead the solar industry. That’s why we have partnered with Petersen Dean, a company that has set the gold standard in solar and roofing installation since 1984 and that proudly supports American manufacturing.
