Underperformance Diagnostics
Have your quarterly electricity bills crept back up, yet your solar panels look completely fine from the ground? Power generation drop-offs are frequently caused by hidden string degradation, shading issues, or sub-optimal inverter tracking that visual inspections fail to catch. At SG Solar Repair, our specialists deploy advanced IV curve tracers to measure your actual daytime array output against factory standards, pinpointing exact generation losses and string failures.
We analyze your historic energy generation data and perform rigorous on-site string testing to restore your system’s efficiency. You receive a clear, comprehensive breakdown of what went wrong, an upfront fixed-price quote to fix it, and a written before-and-after performance report so you can verify that your bill savings are fully recovered.
