Canadian Solar Service We Provide
We service Canadian Solar equipment across Fresno County and Madera County — regardless of who originally installed it.
Panel Performance Testing & Inspection
Canadian Solar panel performance testing using IV curve tracing and thermal imaging. String current analysis, open-circuit voltage testing, and visual inspection for cell cracks, delamination, hot spots, and soiling. We identify underperforming panels and determine whether cleaning, repair, or replacement is needed.
Panel Cleaning & Maintenance
Professional Canadian Solar panel cleaning using deionized water and soft brushes. Soiling analysis, cleaning frequency recommendation, and post-cleaning production verification. Central Valley dust and agricultural particulate significantly reduce output — regular cleaning recovers 5–15% production.
Panel Replacement & Warranty Claims
Canadian Solar panel replacement for failed, cracked, or delaminated panels. Like-for-like replacement with current Canadian Solar HiKu or HiDM series. Warranty documentation support and production verification after replacement.
System Audit & Production Recovery
Full Canadian Solar system audit — panel-by-panel performance analysis, string configuration review, shading assessment, and inverter compatibility check. We identify the root cause of underproduction and provide a prioritized repair plan.

Canadian Solar — Common Questions
What Canadian Solar panels do you service?
We service all Canadian Solar residential and commercial panel series, including HiKu (CS6R), BiHiKu (CS6W), HiDM (CS6L), HiKu7 (CS7N), and older CS6 series panels. We service Canadian Solar panels regardless of who installed them.
How do I know if my Canadian Solar panels are underperforming?
Signs of underperforming Canadian Solar panels include lower-than-expected production in your monitoring app, visible soiling or bird droppings, physical damage to panels, or a sudden drop in production. We perform IV curve testing and thermal imaging to identify the specific cause — whether it's soiling, cell cracks, delamination, shading, or a wiring issue.
How often should Canadian Solar panels be cleaned in the Central Valley?
In the Central Valley, we recommend cleaning Canadian Solar panels 1–2 times per year, typically in spring (after almond bloom) and fall (after harvest dust). Agricultural areas near Fresno, Clovis, and Madera see significant particulate buildup that can reduce production by 10–20% if panels go uncleaned for a full year.
Can you help with a Canadian Solar warranty claim?
Yes. We can document panel defects, perform performance testing, and provide the technical documentation needed to support a Canadian Solar product warranty or performance warranty claim. Canadian Solar's product warranty covers manufacturing defects for 12–25 years depending on the series.
Do you replace individual Canadian Solar panels or the whole array?
We replace individual panels when only one or a few panels are defective. We recommend whole-array replacement only when the majority of panels are degraded beyond economical repair, typically in systems 15+ years old. We always provide a cost-benefit analysis before recommending full replacement.
