Solar photovoltaic net news: in Scotland in 2018 of new green energy by 6%, which means that the region year nearly 75% of total electricity from renewable energy sources, including wind, solar, and hydropower.
in 2018, the Scottish new green energy is mainly comes from offshore wind. The regional offshore wind development has made the whole country in 2018 gained 33% of its electricity from renewable energy. Scotland is one of the best.
in 2030, the British plan gets 30% of its electricity from wind power. Among them, the Scotland has started on a large scale for floating offshore wind power deployment plan, so as to promote the realization of this goal.
not only such, Scotland also ongoing wave and tidal pioneering research, compared with solar and wind energy, its advantage lies in stability.
in the meantime, Scotland is also planning to promote the popularization of electric vehicles. With the revolutionary development of vehicle to grid V2G technology, Scotland plans to fully realize the auto electric before 2032.

years looking for a job is the choice of a large number of job seekers so HR working strength is little sister really hope photovoltaic industry can bring job-seekers remuneration report comprehensive understanding of enterprise's HR as well as provide strong power! Photovoltaic (pv) recruitment network research center launched a joint data & darr; ↓ ↓ 'The photovoltaic industry job personnel salary report 2018' report, very professional, very detailed introduction to the photovoltaic (pv) around the various positions,
early in the history of the solar energy device, mainly for the solar power plant, most of them adopt concentrating collectors, only a minority of the flat plate collector. Flat collector was invented in the late 17th century, but until 1960 after real in-depth research and large-scale application. In the field of solar energy used in low temperature, flat collector technical and economic performance is far better than concentrating collectors. In order to improve efficiency, reduce cost, or in order to meet specific application requirements, developed many kinds of flat collector: according to the classification have air collector and liquid collector of working medium, the extensive use of the liquid collector; According to the heat absorbing plate core materials division of steel pipe, copper, aluminum, copper and aluminum composite, stainless steel, plastic and other non-metallic collector and so on; According to the structure division of tube plate, flat cartridge, tube heat exchanger, the heat pipe fin, the coil type collector, with flat mirror collector and inverse flat collector, etc. ; According to plate division of single or multi-layered glass, glass fiber reinforced plastic or polymer transparent material, transparent insulation material collector, etc. At present, are widely used at home and abroad is the copper collector and copper aluminum composite collector. Copper fin and the combination of the copper tube, foreign generally adopt high-frequency welding, welding using domestic media, China in 199 s has developed high frequency welding copper collector. Copper aluminum composite production line introduced from Canada in 1937, through digestion and absorption, now has built dozens of domestic copper aluminum composite production line. In order to reduce the loss of heat collector, hollow glass, polycarbonate can be used as cover material, such as sunshine and transparent honeycomb board but the material price is higher, difficult to popularization and application.
