PV Testing

FlyThru provides on-site power and electroluminescence checks with immediate results through the use of a mobile testing laboratory. With the ability to test several hundred solar modules per day in standard test conditions (STC), the rolling laboratory produces a swift and accurate overview of the condition of a commercial solar installation.

With each panel that is inspected, checks are simultaneously conducted to determine power production under STC using an A+A+A Long-Pulse LED solar simulator and EL checks through an enhanced high-resolution system to highlight internal module flaws such as micro cracks, inactive areas or hotspots. An option of additional thermal testing is available with the PV-testing system to further supplement on the spot solar inspections.
