Testing & Measurement

Thermal Camera Hot-Spot Measurement

Detect hot spots on panels with drone and handheld thermal imaging under IEC 62446 / 61215.

IEC 62446 / 61215

Hot spots may form after solar panels are commissioned. We perform this inspection with both drone and handheld thermal cameras. With the IS2 files provided by the software, you can make a declaration to the panel manufacturer. Thermal inspection of solar plants is critical for detecting problems.

Thermal Camera Hot-Spot Measurement

Why Is It Needed?

What Can You Learn?

Damaged Cells

Detect whether there are damaged cells in your solar panels.

Unexpected Heating

Identify unexpected heating in bypass diodes, junction boxes and other panel materials.

Shading Effects

Detect whether environmental shading factors have damaged panels.

Inactive Strings

Identify strings that have never been commissioned.

Scope

EL (Electroluminescence) Test

Cell Structure

Learn about the structure of the cells.

Crack Detection

See whether cells have cracks or damage.

Installation Effects

Detect effects of overhead carrying during EPC installation or panel stress.

FAQ

Frequently Asked Questions

Overheating points on a panel that can cause performance loss and damage.

Once a year or more frequently, depending on plant conditions.

No. EL testing does not provide panel power; it helps identify the source when a problem is found in I-V measurement.
