How do solar panels work?
By Tom Tate
If a person had a Rip Van Winkle moment and fell asleep under a tree a decade ago, they would be amazed at how far solar photovoltaic (PV) systems have come. And they’d be right to feel that way as the technology continues to evolve at a rapid pace. Once the most expensive form of electricity generation, economies of scale in manufacturing and advances in technology are steadily driving prices down.
The typical PV system has two main components, the panels and the inverter. Disconnect switches are also necessary so the system can be safely isolated for maintenance and other reasons.
