Our Technology
The Sunrayker CSP-CPV energy system is a low-level concentrator, concentrating the sunlight 40 times (40x).
A multi-faceted parabolic like collector that reflects the sunlight onto a small photovoltaic receiver. A passive heat sink maintains the photovoltaic cells at a cool temperature, allowing a higher power output. The electricity from the photovoltaic cells is used heat an electric thermal storage tank to 800°C (1472°C). This high temperature enables the thermal generation of electricity to occur more efficiently.
The photovoltaic cells used are n-type monocrystalline silicon cells. Since a small amount of low cost monocrystalline silicon material is used, solar cells specifically designed to operate within the concentration ratio can be developed, so the newest most efficient cells can be used.
The thermal system consist of a parabolic dish that reflects the sunlight down onto a thermal receiver located near ground level. The solar energy received by the thermal absorber heats a working fluid to temperatures in the region of 450°C (842°F).
Thermal storage will enable the solar farm to generate disbatchable electricity during the peak energy demand periods of the day.
To harvest as much energy as possible the solar collector and receiver are mounted on a purpose built dual axis tracking system. Integrating both the CPV and thermal systems onto the one machine fully utilizes the dual axis tracking system, increasing efficiencies and reducing the capital cost. The design of the system eliminates the need to use expensive solar tubes, rotating joints or flexible hoses.
The Sunrayker solar energy harvester is able to collect up to five times more energy than a photovoltaic solar energy system of a similar size.
