Analysis of Cooling System Parameters by Solar Concentrating Panel with Fresnel Lens

Solar energy concentration technology using Fresnel lens is an effective way of utilizing solar energy due to its thin, lightweight construction that are available in different sizes, with excellent light absorbing ability for a variety of applications. Concentrated photovoltaics is a major application and the highest solar-to-electric conversion efficiency, the Fresnel lens are reported about 30% higher efficiency. An attempt has been made to state the advantages of the use of Fresnel Collectors in concentrating solar power. The work studied about PV cells that are used with a lens arrangement system inbetween them, and for heat reduction a cooling system is also attached to maximize the efficiency. By using Fresnel lens, the output of PV cell can be maximized and the cost can be minimized. Here it is found that, with low cost of arranging the system can obtained the power output 2-2.35 times higher than normal PV panel system, i.e. the cost can be reduced in half or power output can be maximize double or greater for a given cost. The maximum performance from this system is around 62.7% increases that is quite satisfactory. Although the present application scale is small, the ongoing research and development works suggest that Fresnel lens solar concentrators can be a alternative system with higher efficiency than conventional type system. It will bring a breakthrough of commercial solar energy concentration application technology in the near future. The efficiency of solar systems, in particular photovoltaic panels, is generally low based on temperature and the output of the P.V. module is adversely affected by their surface rise in temperature. This increase is associated with the absorbed sunlight that is converted into heat, resulting in reduced power output, energy efficiency, performance and life of the panel. The use of cooling techniques can offer a potential solution to avoid excessive heating of P.V. panels and to reduce cell temperature.
