SHARP high reliability solar battery life of up to 35 years

Left for thin film silicon type, single crystalline silicon and polycrystalline silicon solar cell module with residential type. Improved silicon substrate and wiring connection method to reduce the negative impact of heat. Multi crystalline silicon solar cell module of the April 14, 2006 launch of SHARP solar cell module with higher reliability of silicon material housing. The conversion of multi crystalline silicon and representative module of single crystal silicon efficiency were 13.3% and 14%, basically the same with the previous products. The main model for the output power of polycrystalline silicon solar cell module "153W ND-153AU", suggested retail price of 72 thousand and 450 yen. The improvement of the solar cell with the silicon substrate and the connecting part has the following characteristics: the reliability of the wiring material, the silicon substrate and the connection of the wiring are improved. The product is said to have been developed in a solar powered solar cell. Specifically, there are three unique designs: the use of flexible copper in the wiring; a portion of the wire to be of a scalable shape; the silicon substrate and the wire set in the absence of solder. The pressure can be reduced due to the difference of the thermal expansion of the connection and the silicon substrate, so that the load applied on the silicon substrate is reduced to about 1/3. By improving the connection and connection method, so that the design phase of the connecting part of the service life from the original 25 years to be extended to 85 years. Through the improvement, the service life of the module is extended from 25 years to 35 years. In addition, the service life is referred to as the failure rate of 10ppm, and the product shelf life is different. Thin film silicon solar cell silicon except for residential products, with a thin silicon material for solar battery module "residential NA-851WU" will be listed in July 1, 2006. Since September 2005 the company began production of thin film silicon, for industrial use. This time, in order to compensate for the lack of materials due to insufficient supply of crystalline silicon material, silicon thin films will be decided for residential use. In accordance with the principle of "not a temporary measure, the future will continue to sell" (SHARP solar business this minister executive director Fuda Koji), the company will increase the annual production capacity of 15MW thin film silicon material as soon as possible. NA-851WU output power of 85W, the proposed retail price of 60 thousand and 480 yen. Module conversion efficiency of 8.1%.
