Solar photovoltaic panels that follow the sun
A solar tracker is a device that follows the sun as it moves across the sky. When solar trackers are coupled with solar panels, the panels can follow the path of the sun and produce more renewable energy for you to use. Solar trackers are usually paired with ground-mount solar systems, but recently, rooftop-mounted. Solar trackers can greatly increase the cost of a photovoltaic solar installation. A standard 4-kilowatt ground-mounted solar system will cost about $13,000. Tracking equipment can cost. In most cases, solar trackers are not worth the additional investment, even though they do produce more electricity. Because solar panels are cheaper than ever, it would cost less to install. In almost all scenarios, especially for residential solar systems, solar trackers are not worth the additional investment. This is why solar trackers aren't widely used in the residential solar industry. Where solar trackers do.
