1 Overview
The WilliamsRDM Solar Tester (
Figure 1
) is built to test the voltage, current and power output of the
WilliamsRDM covert solar devices and other equivalent solar systems. The tester can be used to verify proper
operation and wiring of repaired cables and solar panels. It can also be used to measure the performance of the
solar panels in a deployed location to verify operation and power output. Using the optional paint adapter kit,
the solar tester can be used as a guide to apply WilliamsRDM’s custom formulated paint to the covert solar
devices in the field without the fear of over painting and thus degrading the solar devices.
