2. Introduction In general, solar power generation involves the conversion of solar energy to electrical energy. This can be implemented through different technologies such as photovoltaics or heating a transfer fluid to produce steam to run a generator, for example. In some solar power generation systems one or more heliostats may be used to reflect solar radiation onto a collection point to enhance overall efficiency. Typically, each heliostat is controlled to track the sun and maintain reflection of the solar radiation on the collection point throughout the day. The solar radiation received at the collection point may be converted using any known technology. Typical conversion methods include thermal conversion using solar-generated steam or other working fluids, or direct conversion to electricity using photovoltaic cells. On larger scales, solar power generation from concentrated sunlight may employ fields of multiple heliostats for solar energy collection. Each heliostat typically requires power distribution in order to drive the motor positioners and data communication in order to facilitate sun tracking control.

3. Solar Thermal Energy Solar thermal energy is technology for harnessing the energy from the sun and converting it to thermal energy. This can eventually procured into electricity through different routes. One of the most popular and effective means of this conversion is through the heliostat. A heliostat is a mirror based device which tracks the movement of the sun in a fixed direction, typically the thermal energy which is generated is directed onto a thermal receiver. This is expensive material!

4. Disadvantages of Existing Solutions Human Maintenance The system is turned off and on a specific times - not necessarily when there is feasible capture possible. That is, generation times are not specific to the Gregorian Calendar Wireless Communication Rather than Direct Environmental Conditions The system is not programed to adjust for live-weather conditions that can damage the material. As most systems are built in the desert, it is important to provide protections from the extreme weather conditions.

5. Our invention addresses these problems by... 1.Maximizing the solar-thermal energy generated from the heliostate on a day-to-day basis 2.Self-protecting features in times of extreme weather conditions Automation removes the last component of human maintenance, thereby maximizing energy production and eliminating human assigned error.
