Performance Objectives

Students should be able to:

  1. Examine the units in Industry, Electrical continuity Testing
  2. Describe the solar panels or solar collectors for energy supply


Testing solar panels can often be frustrating and time consuming. Seaward Solar has provided a tool that allows you to complete an array of tests, with the push of a single button.

When testing PV arrays, you might find that you’re faced with juggling at least three different instruments for the job, for instance, a continuity/insulation resistance tester, a digital multimeter and a DC current clamp. Aside from the inconvenience of having to lug around multiple tools, these devices are not typically designed for direct connection to PV system interconnections, so you can find yourself resorting to makeshift test adaptors and short circuiting the PV strings for short circuit current measurement. This can pose the risk of accidental.... View More
