Solar PV testing with PPM Solar
Whatever your solar PV testing needs are, we have you covered.
Are you using traditional tools to test solar PV installations?
Using traditional tools such as a clamp meter or multimeter to test and troubleshoot solar PV installations takes a lot of time. The accuracy of your results can vary.
There is a quicker and more accurate way to test solar PV systems, which could give you extra time to book more jobs and make more money.
PPM Solar provides a number of PV test solutions for residential, commercial and utility solar systems, These solutions are used and trusted by 1000’s of solar PV professionals across the world.

Inspections with Infrared Thermography
Solar system testing presents unique challenges to all operators – from homeowners to utilities. Compared to routine testing and commissioning, Infrared (IR) scanning can resolve some of these challenges at a fraction of the cost and time.
IR thermal imaging is performed by handheld devices and drones. PPM Solar has all the equipment and a licensed drone pilot on staff.
Thermal Scans allow for exceptions or anomalies to be clearly defined and detailed in the thermal image. Scanning is performed under normal operating conditions without disruption of service. Inspection is conducted to locate: dead strings, hot spots, gas pockets, cell cracks, short circuits, and other anomalies in PV arrays.
-V Curve Testing is a comprehensive commissioning test. PPM Solar carries out all commissioning services required by IEC 62446:2016. We measure the relationship between current and voltage while varying the electrical load from open circuit to short circuit. This produces a characteristic current vs voltage (I-V) curve. Measurements are then converted to STC and module performance is verified.
This highly controlled test includes the measurements of current, voltage, ambient temperature, cell temperature, irradiance, and insulation resistance.
Advantages of Advanced PV Testing
New Projects: Quickly assess compliance and proper completion of your solar project.
Existing Projects: Maximize your revenues by quickly identifying weak links and conducting preemptive, early, and general service. This will help keep manufacturers and contractors accountable for their warranties.

Frequently Asked Questions
What is solar PV Testing?
PV testing is the testing of each individual module that connects a PV array.
Why do you test commercial solar installations?
To ensure maximum energy output, determine if there are any malfunctions or defects, evaluate thermal fulfilment and check for any power surges. Any issues can cause losses to commercial businesses, especially if they have to shut down while waiting for repairs or replacement.
How do you carry out solar PV Testing?
Pre-installation testing is done on the individual modules. It can also be done during system operation, and while maintenance is being performed.
Do you provide PV Testing service for residential installations?
Yes! PPM Solar offers residential solar system testing via infrared (IR) scanning. IR thermal imaging is performed by handheld devices and drones. PPM has all the equipment and a licensed drone pilot on staff. We also offer I-V Curve Testing (a comprehensive commissioning test). This highly controlled test includes the following measurements: current, voltage, ambient temperature, cell temperature, irradiance, and insulation resistance.
