Solar Testing Equipment

Test equipment for PV cells, modules, panels, and arrays should be capable of performing the types of measurements that typically characterize such PV components and systems, including short-circuit current testing and open-circuit voltage testing, Additional PV measurement capabilities include solar responsivity or how a PV device responds to different wavelengths of light and how efficiently it can convert light to electricity.

Useful test equipment capabilities include wide I and V measurement ranges, high AC and DC power accuracy, and high resolution. Any PV-based source of electricity will require evaluation of inverter efficiency or the ratio of the inverter’s DC power input to its AC power output. A power analyzer capable of simultaneously measuring DC input power and AC output power can simplify this task.

Where measurements are performed, such as in the R&D lab or production line versus in the field, will help determine the desired form factor of the test equipment. Whereas engineering and production applications are well served by standard rack-mount test units, on-site measurements of PV installations may require portability and high accuracy across wide temperature ranges since PV energy-producing setups and systems can be subjected to extreme environmental conditions. The amount of testing required will depend upon local regulations.
