Definitions

  • This invention generally relates to an adjustable solar panel mount, and more particularly, to a solar panel and wind generator mounting apparatus with a plurality of arms featuring independent pitch andrpll adjustments and a rotatable vertical axis for yaw adjustment.
  • Solar cells produce direct current electricity from sunlight, which can be used to power equipment or to recharge a battery. Efficiency of the process depends in large part upon the orientation or angle of inclination of a panel relative to the sun's rays. In general, to get the most from a solar panel, it should be oriented in a manner that captures the most sun. However, there are a number of variables in figuring out the best direction. The optimum orientation may vary according to geographic location, times of day and year, and topography.
