Harvesting solar radiation and converting into useful heat has been subject of intense research because of its use in a wide variety of engineering applications. In early years of solar energy implementation, the direct conversion of solar radiation to electricity using Photovoltaics took the center stage and except for the space applications, it was not considered for common use because of its cost. However, with recent advances in Photovoltaics manufacturing, the cost of solar electricity generation has plummeted to about $0.07 per Kwh making it the most affordable for  everyday applications. Photovoltaic power plants and wind farms are being inherently intermittent, solar thermal heat storage and power generation will complement the existing renewable energy grid. Since storing electricity is not a particularly efficient process and heat storage being far easier and efficient method, solar thermal becomes very attractive to large-scale energy production. 

Many manufacturing industry uses saturated steam at relatively low pressures. A novel flat solar panel, Multiple Parabolic Reflector Flat Panel Solar Collector, is described to heat a working fluid to a maximum temperature of 150oC.  The parabolic reflectors in the panel remain stationary, while the receiver moves to track the sun, thereby allowing for maximum energy collection with minimum amount of sun tracking.  


Abridged Biography
