Field-based drone EL testing for solar plants in Kenya, DRC, Madagascar, Zimbabwe, Mozambique, and Rwanda. The factory gold-standard test, delivered on-site: every cell, every module, no dismantling.
Solar modules are wired in series, so a string only produces what its weakest module allows. A single cracked or degraded module quietly squeezes the output, and the profit, of every healthy module around it. Across a utility-scale plant, undetected cell defects compound into significant lost revenue every day.
EL testing finds those weak modules with certainty, at cell level, so you fix the bottleneck instead of guessing at the symptom.
Traditional EL testing means uninstalling modules and shipping them to a laboratory. Field-based drone EL brings the laboratory to your site.
No uninstalling, no transport damage risk, no re-installation cost. Modules are tested exactly as they operate, in place.
Autonomous drone flight maps entire blocks per night. What a lab tests in weeks, a field campaign covers in days.
Campaigns are flown at night or with minimal interruption, so your plant keeps generating revenue while it is being diagnosed.
Defects are assessed in the module's true electrical and environmental context, with results mapped to exact plant locations for repair crews.
VersaDrones delivers PV electroluminescence testing with licensed local pilots and in-country permits in Kenya, the Democratic Republic of Congo, Madagascar, Zimbabwe, Mozambique, and Rwanda, with Nairobi as our operational base for East Africa.
Under EL, every solar cell emits light where it works and stays dark where it doesn't. The result is an X-ray-like image of the electrical health of your modules.
Hairline cracks from transport, installation, hail, or thermal cycling. Invisible to the eye and to thermal cameras until output has already dropped.
Potential-induced degradation, failed solder joints, and broken interconnects show up as dark cells and regions, classified defect by defect.
Every module scanned becomes a documented, comparable record: the baseline evidence that anchors warranty claims, insurance cases, and asset valuations.
Check for construction and transport mishandling, ensure a defect-free system at COD, and establish baseline documentation before the warranty clock starts.
Find the bottleneck behind underperformance, optimise output, support revamping and repowering decisions, and substantiate warranty or insurance claims after storms and hail.
Technical due diligence before acquisition, yield improvement planning, and the hard condition data that lenders, insurers and buyers increasingly expect.
Our partner Quantified Labs pioneered patented autonomous drone electroluminescence mapping: thousands of modules imaged per campaign at lab quality, with AI-powered analytics classifying every defect into a digital twin of your plant.
VersaDrones provides the in-country operational layer: licensed pilots, KCAA and national airspace clearances, night-operations planning, and field logistics across Kenya, DRC, Madagascar, Zimbabwe, Mozambique, and Rwanda.
