All solar panels are not created equal. SolarWorld controls every aspect of the manufacturing process to deliver high-quality solar panels that provide long-term energy production for each and every customer. Maximize your return on investment with worry-free performance.
- We test and retest our solar panels for performance in the real world, not artificial laboratory conditions.
- Our panels will perform consistently for decades; others put cutting upfront costs ahead of ensuring long-term performance, potentially costing you thousands over the life of the system.
- With a proven track record that spans more than four decades, we’ll be here to honor warranties and service commitments for years to come.
Our plus-sorting and solar panel design ensure you get all the energy you pay for. Only solar panels achieving or exceeding the designated nominal power in performance tests are available to customers. The power tolerance ranges between -0 Wp and +5 W. That equals more savings and greater results from your solar system.
With real-world performance proving SolarWorld produces the highest quality solar panels, we can guarantee the best performance. That's why SolarWorld offers a 25-year linear performance guarantee on the Sunmodule Plus series. A 20-year product workmanship warranty is also standard with every solar panel we sell.
SolarWorld technologies are different because we are different. Our commitment to quality powers our success and is why our solar panels consistently produce clean energy for at least 25 years—even in the harshest weather conditions.
Here are just a few of the numerous tests that our solar panel testing lab conducts:
- Salt mist spray for coastal areas
- Snow and wind load testing
- Hail impact tests
- Corrosion tests
Your solar investment is only as good as a solar system’s ability to produce energy. Achieving maximum energy output is our priority. Every SolarWorld solar panel undergoes stringent quality checks throughout the manufacturing process.
