A photovoltaic array is just one of a few different types of solar technology on the market. There are a number of other system setups, each serving a slightly different purpose.

Concentrating solar power (CSP) systems rely on reflective devices such as mirror panels to concentrate the sun’s energy and produce the heat needed to generate electricity.
Solar water heating systems employ solar “collectors” to gather heat from the sun. That heat is then channeled down into a tank of water to warm it.
Solar air heating systems also use collectors to harvest solar thermal energy. Unlike solar water heaters, however, these setups use the collected energy to preheat ventilation air for homes and commercial buildings.
