“The price of failure with defects on a finished project is severe, and it’s simply not worth trying to save a few dollars upfront only to be bitten down the road with failures. That’s why we partner with SepiSolar for all of our engineering and design needs for solar and storage.”

Ben Lochtenberg,
CEO of Xero Solar
