Say simply, each such & other; Solar flower & throughout; , by training base, engineering design servo mechanism of solar panel and door leaf. Solar photovoltaic (pv) network statement: this information is reproduced from the media or other Internet web site, network cooperation photovoltaic network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. This paper not only includes editor Wolfgang & middot; Parr, Dr Himself in his new energy career of more than 50 years, the deep understanding of the development of photovoltaic (pv) and the system summary, also include the global photovoltaic industry professionals engaged in new energy or a review of the photovoltaic difficult development, americans launched smartflower POP, this is a kind of habit in imitation of a sunflower design and manufacture of solar power device, automatically open, automatic tracking sun, generation capacity increase 40 times, no heat exchange a & other; Solar flower & throughout; , ideally, can satisfy a demand of modern people a year. The article content is for reference only. In actual use, or will be affected by the local sunshine time, however, the old beauty seems to be going to use to solve the efficiency problem, they are going in the promotion, to provide auxiliary power supply for family, field, or vehicles, and convenient installation, can fully deployed within hours, also offers a variety of types of optional, in addition to the usual plug-and-play model, and model of the battery system, electric energy can be stored, no heat to centralized power supply. Battery charging curve, base its capability of providing basic fixed, and under the drive of servo mechanism, the whole solar panels can fold during the night or when necessary, with the sun's rays and can expand, as well as incident Angle of sun tracking and ensure its power generation efficiency is highest at any time! Engineering design training systems engineering 'the world' of photovoltaic (pv) is a comprehensive system to introduce photovoltaic summary of past, present and future of the development of corpus, wide-ranging, can meet the needs of different readers.
