ELECTROLUMINISCENCE INSPECTION IN
THE FIELD

WHAT IS CELSOS?
CELSOS is CENER´S ELECTROLUMINESCENCE SYSTEM ON-SITE.
CELSOS diagnoses the health of PV plants using the depth of analysis given by the Electroluminiscence technology together with the efficiency of aerial inspection and the power of the AI.
CELSOS has been developed by CENER by leveraging knowledge and experience in the photovoltaic technology for the last 20 years.
CELSOS IS HIGHLY VALUABLE WHEN…
- Quality control of PV plants under construction or commissioning.
- Predictive maintenance helpful.
- Underperformance situations assessment and understanding.
- Warranty claims checking.
- PV plant repowering/revamping decisions.
- Plant inspection for insurance claims.
- Evaluation of PV assets for transactions.
ADVANTAGES
Up to Cell level diagnosis.
Accurate and cost-efficient.
Massive diagnostics, not limited sampling.
EL images are captured at night, no interference with plant operations.
Applicable to all kind PV installations: utility scale ground mounted, rooftop, BIPV, floating…
CELSOS PILLARS

AERIAL ELECTROLUMINESCENCE INSPECTION OF THE PV PLANT
CELSOS aerial inspection combines state-of-the-art UAV technology for EL image capture with fastbiassing hardware and on-field procedures developed by CENER.
More than 4 MWp of inspected modules per night are now possible thanks to CELSOS aerial inspection!
KNOW MORE FEATURES
Remote and synchronized control of the drone, the DC power supply, the connection suitcase, and the EL camera.

Illustrative example of several types of defects detected by EL in a unique PV module.
CRACKS TYPE C Substrate scratch
CRACKS TYPE B Tabbing problem
CRACKS TYPE A Degraded cells(LeTID)*
*A low biasing EL image was captured to rule out PID cause

CELSOS ANALITICAL SOFTWARE
CELSOS Software takes advantage not only of the AI and machine learning technologies but of the vast experience of CENER laboratories of dealing with PV modules technologies and troubleshooting.
KNOW MORE FEATURES
Diagnosis and influence of the defects in the
electrical performance of the module (at present
and in the near future). Come out.

CELSOS INTERACTIVE PLATFORM
In addition to the standar technical repot, the client can access via web to an interactive map of the PV installation showing either aggregated inspection result and by module after the advanced analysis of the EL images captured in the field.
KNOW MORE FEATURES
– Type of defect: kinds of cracks, scratch, PID, corrosion,…
– Severity of defect: Minor, Major, Critical.
Exportation of all the data of selected modules on a CSV file.
