Useful for Solar Thermal Energy Systems
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.
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!
Wireless Communication Rather than Direct
Automation removes the last component of human maintenance, thereby maximizing energy production and eliminating human assigned error.
