One of the biggest challenges in developing a laboratory is obtaining sufficient funding to purchase all of the desired components, tools, and equipment for meaningful demonstrations, laboratory experiments, data collection, and hands-on learning experiences. As an alternative to a more complete facility, the table below is an example of an excellent starter laboratory that includes a complete 2040 Watt PV system and the instrumentation necessary to conduct a variety of meaningful exercises and collect useful data on component and system performance. The total cost is less than $10,000.
