A solar energy device is a system or series of mechanisms which collect and transfer solar generated energy and which is designed primarily to:

• Provide heating
• Provide cooling
• Produce electrical power
• Produce mechanical power
• Provide solar daylighting
• Provide any combination of the above by means of collecting and transferring solar generated energy into such uses either by active or passive means, including wind generator systems that produce electricity.

Solar energy systems may also have the capability of storing solar energy for future use. Passive systems must clearly be designed as a solar energy device, such as a trombe wall, and not merely as a part of a normal structure, such as a window. Only a system or device which performs one or more of the above functions qualifies for the Solar Energy Credit. An individual component of a system does not qualify for the credit by itself.
