1.目的
化石燃料代替エネルギーとして、またCO2削減の観点からも、自然エネルギーの活用が要望されている。その中でも、太陽光は、無尽蔵のエネルギーであり、太陽光をエネルギーに変換する技術も確立している。そのため、太陽光発電システム(PVシステム)が脚光を浴びており、家庭用やメガソーラー等の大規模太陽電池アレイが設置されるなど、PVシステムは急速に普及している。
英文要約Title:Prototype development of the trouble degradation sensing equipment(FY2009-FY2010)FY2009 Annual Report
1.Purpose:The use of natural energy is demanded from the viewpoint of the fossil fuel alternative energy and the CO2 reduction. Sunlight is the unlimited especially energy, and the technology that converts sunlight into energy has been established, too. Therefore, the solar photovoltaic system (PV system) steals the limelight, and it is rapidly widespread. The technology that detects trouble and the degradation of the solar battery at the early stage is developed to spread the PV system, the reliability of the system is improved, and it is indispensable to reduce the cost that hangs to the inspection and maintenance, and to lower the power generating cost relatively. This development discovers the trouble module in the PV array of the PV system, and develops the technology and the device that specifies the position of the trouble module.
2. Establishment of the error place specifying technology
The TDR(Time Domain Reflectometry ) method is a technique for measuring the impedance of the measurement object by impressing the signal from one edge of the transmission line aiming at the measurement object, and observing the response waveform from the measurement object. The technology that detects the breakdown and deterioration in the PV string by the change in impedance is established by using the TDR method. The wavy observation device to observe the pulse generator and the reflection wave type into which the voltage and the pulse width, etc. were changed was designed for that. In addition, the technology that detected the trouble and the degradation position was developed, and the method of detecting one module trouble location with the resistance of 10Ω that existed in the PV string by the accuracy was established.
3. Prototype development of the trouble degradation sensing equipment
The change for the failure diagnosis of the PV module was added, and the prototype of the trouble degradation sensing equipment was developed for an existing equipment. The specification of the product was extracted from the feature of a necessary output wave type and the input wave type by using the prototype, and the prospect that commercialization by the price accepted in light, making to compact, and the market of the extent that was able to be carried was able to be achieved was set up.
4. Business plan
Information on the target price for the equipment when the hardware requirement and the maintenance trader necessary for the maintenance work in the on-site owned this development product as a result of doing hearing to the solar battery module maker was obtained. The problem for the product image, prices of manufactured goods, the market trend, the market scale, and making to the business and the profit and loss plan, etc. were examined, and the business plan for making to the business was settled on.
