Consider a large solar photovoltaic (PV) plant with 300 000 PV modules or panels as they are commonly called. How do you know whether they meet the quality or power output standards specified by the manufacturer? You will need to test 300 to 500 of them on a plant of this size, preferably before installation or on site if they are already installed. With solar PV being one of South Africa’s fastest growing industries, it is essential to independently test the quality, performance and durability of a sample of modules at every plant. The size of the sample is determined by the size of the plant according to specific standards.
