  1. 6. ___Temperature – The air temperature of an environment.
  2. 7. The angle at which the sun is hitting the array.
  3. 9. The number of days a fully charged battery system can supply power to loads without recharging.
  4. 10. When current flows into the grid.
  5. 13. A device used to convert direct current to alternating current.
  6. 14. The panel support system, wiring, disconnects, and grounding system that are installed to support a PV array.
  7. 15. tracking An array mounting system designed to adjust both the horizontal and vertical axes of a panel to precisely follow the movement of the sun.
  8. 18. A low-efficiency type of photovoltaic cell characterized by its ability to be used in flexible forms. Also known as thin film.
  9. 21. A temporary decrease in grid output voltage typically caused by peak load demands.

  1. 1. A diode used to direct current around a panel rather than through it. Bypass diodes are typically used to overcome partial shading.
  2. 2. A device that maximizers the collection of solar energy by using mirrors or lenses to focus light onto specially designed cells.
  3. 3. A completed PV power-generating system including panels, inverter, batteries, and charge controller (if used), support system, and wiring.
  4. 4. The measure of a location’s relative height in reference to sea level.
  5. 5. A measure of the amount of charge removed from a battery system.
  6. 7. For a PV array, the azimuth angel is the angle clockwise from true north that the PV array faces.
  7. 8. A junction box used to connect strings of solar panels to create a larger array, and to provide a convenient array disconnect point.
  8. 11. The thickness of the atmosphere that solar radiation must pass through to reach the earth.
  9. 12. The angle between the equator and the rays of the sun.
  10. 16. A method of determining a location on Earth in reference to the equator.
  11. 17. A measure of radiation density at a specific location.
  12. 19. A grid-interactive system used with other energy sources, such as wind turbines or generators.
  13. 20. A material in which specific impurities have been added to produce a positive or negative charge.
