Is $560 to replace a defective Hanwha QCells solar panel and optimizer a fair price?
Project Details
I am having a disappointing experience with my QCells solar panels. One panel, only 6 years into a 25-year warranty, is underperforming by about 40% due to a confirmed manufacturing defect. QCells acknowledged the defect but is only offering a $149.63 warranty credit because the exact panel model is discontinued. My installer, who stopped carrying QCells several years ago due to quality and support issues, quoted me $560 to replace the panel and optimizer. I feel this small credit is insufficient given the significant production loss, and I was hoping for a full replacement or at least reimbursement for labor. The panel is not shaded, and I'm frustrated by QCells' poor customer support and their insistence on a minimal payout. I'm now considering if the replacement is even worth the cost given the breakeven period.
