Across
- 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.
- 5. rate of flow of electric charge, measured in amperes.
- 7. (1) of or pertaining to the sun. (2) utilizing, operated by, or depending on solar energy. (3) manufacturing or providing solar power.
- 9. photovoltaic modules connected together to provide a single electrical output.
- 13. measure of solar radiation energy received on a given surface area in a given time.
- 14. method of harnessing solar energy for thermal energy (heat).
- 15. basic unit of a photovoltaic panel.
- 16. ratio of light reflected from a surface.
- 18. distribution of energy emitted by the sun arranged in order of wavelengths.
- 19. light from the sun; also called solar radiance.
Down
- 1. energy from the sun that is converted into thermal or electrical energy.
- 2. an electric current in which electrons flow in one direction only.
- 3. potential energy that makes the electrical current flow in a circuit by pushing the electrons around (pressure).
- 6. a solar array that follows the path of the sun to maximize the solar radiation incident on the photovoltaic surface.
- 8. an electric current that reverses direction at regular intervals.
- 10. device that converts DC electricity into AC electricity.
- 11. unit of electric current (refers to flow of current)
- 12. standard unit of voltage; one volt produces one ampere of current when acting a resistance of one ohm.
- 14. energy derived from the sun in the form of solar radiation.
- 16. height of the sun above the horizon.
- 17. interconnected assembly of solar cells; also called a panel.
