Backyard solar tracker
An important component of solar installations are trackers, the structures that hold up solar electric panels and position the panels toward the sun during the course of the day. This system here from AllSun Trackers, which could be used in a residential home yard, includes an inverter to convert from direct current to household electrical current. In high winds, the system will flatten out and lock in place.
