Today’s technology in the solar energy field allows the use of solar energy in the form of a clay roof tile system. This innovative product allows SSNGA to provide an attractive, permanent roof system. The tiles are linked together in a wiring loop that produces DC power. Each tile produces 21 Watts when arrayed in proper angle to the sun.
The power generated is safe and efficient low voltage. The power is fed to a battery bank in this DC form and is available to power DC lighting, appliances, and equipment. The battery bank is charged by the same solar tile arrangement resulting in a sustained energy cycle with a long life span. These developments in DC power are the answer to “off grid” in the strictest sense. The one additional element to consider is a small alternative energy source, such as a generator to be used as a backup to charge the battery bank during an extended period without sunshine. This can be overcome by a larger battery array.
Using the same innovative roof tile system, the power generated and sent to the battery bank can then be inverted to AC power. The power is then available to be used in the traditional sense. This arrangement is generally in concert with a “grid” connection to the power company’s electrical grid. As we look toward the future, this extra capacity will be available to sell back to the grid using the concept known as net metering.
