Why Our Testing Matters
Long-term field data does not exist for solar power plants.
Over 80% of the world’s installed solar capacity has been operating for less than five years. PVEL’s expert, independent lab and field testing creates the data that developers need to procure reliable equipment and forecast system performance. Our testing suite is designed to facilitate project financing.
