  1. 4. the unit of electric power, or amount of work (J), done in a unit of time. One ampere of current flowing at a potential of one volt produces one watt of power.
  2. 5. rate of flow of electric charge, measured in amperes.
  3. 7. (1) of or pertaining to the sun. (2) utilizing, operated by, or depending on solar energy. (3) manufacturing or providing solar power.
  4. 9. photovoltaic modules connected together to provide a single electrical output.
  5. 13. measure of solar radiation energy received on a given surface area in a given time.
  6. 14. method of harnessing solar energy for thermal energy (heat).
  7. 15. basic unit of a photovoltaic panel.
  8. 16. ratio of light reflected from a surface.
  9. 18. distribution of energy emitted by the sun arranged in order of wavelengths.
  10. 19. light from the sun; also called solar radiance.

  1. 1. energy from the sun that is converted into thermal or electrical energy.
  2. 2. an electric current in which electrons flow in one direction only.
  3. 3. potential energy that makes the electrical current flow in a circuit by pushing the electrons around (pressure).
  4. 6. a solar array that follows the path of the sun to maximize the solar radiation incident on the photovoltaic surface.
  5. 8. an electric current that reverses direction at regular intervals.
  6. 10. device that converts DC electricity into AC electricity.
  7. 11. unit of electric current (refers to flow of current)
  8. 12. standard unit of voltage; one volt produces one ampere of current when acting a resistance of one ohm.
  9. 14. energy derived from the sun in the form of solar radiation.
  10. 16. height of the sun above the horizon.
  11. 17. interconnected assembly of solar cells; also called a panel.
