Description

A kind of photovoltaic module erection tower at rotatable pair of inclination angle
Technical field
The present invention relates to photovoltaic module installation rack, the photovoltaic module for being specifically related to a kind of rotatable pair of inclination angle installs tower Frame.
Background technology
Photovoltaic module, is also solar panel, is the core in solar power system, is also solar power generation Most important part in system, its effect is to convert solar energy into electrical energy, and is sent in battery and stores, or passes through power network Promote loaded work piece.
Because photovoltaic module energy density is low, floor space is big, and 100W photovoltaic modulies need the installation no less than 1 square metre Area, while existing photovoltaic module ground is arranged on occupancy a large amount of areas, it is necessary to smooth to fabricating yard progress, to whole Plant is rooted out, and builds high-density installation foundation pile and support, also fabricating yard is hardened or covered, to prevent Weeds shrub grows shield photovoltaic module, and influence generates electricity.The projected life that photovoltaic is installed is not less than 25 years, also implies that, light Volt component installs shared land area and completely loses plant growth function, and permanent influence is caused on ecological environment, also wastes big Land function is measured, and the recovery land function difficulty that expires is larger.Also, surface-mounted photovoltaic module, because of terrestrial surface radiation heat Generate heat superposition, radiate insufficient naturally with photovoltaic module, can influence to generate electricity.Ground photovoltaic plant will also in flood-protection, fire-proof, Anti- animal is damaged, and management is put into terms of anti-weeds shrub shield, causes cost further to increase.
Because the existing mounting means of photovoltaic module has the drawbacks of floor space is big, therefore, photovoltaic is seriously constrained new The development of the energy.20 mu of area occupied is installed with 1MW photovoltaic modulies, China increases installation photovoltaic component 15GW or so newly every year, needs 300,000 mu of area occupied, this does not include annual natural increase also.Photovoltaic area occupied function is single, it is difficult to comprehensively utilize, directly Increasing for lease cost is result in, the inclement conditions such as western desert, gobi, deserted mountain, barren beach area can only be selected to carry out installation and built If counting China's photovoltaic generation 85% installed in such area according to National Energy Board, and these areas are often away from inhabitants live With institute of economic activity area electricity, it is impossible to on-site elimination, the power consumption area conveying of long distance descriscent is needed, cost is high, loss is big.
Area accounts for the 42.9% of area, but the population in the whole nation 94.4% of living to the east of China's Heihe Tengchong line, to the west of Area accounts for the 57.1% of area, the population in the whole nation 5.6% of but only living.The most of economic activity of China concentrates on black Regional to the east of the Tengchong line of river, western half portion is made up of plateau, desert, gobi, salt-soda soil more, and the wasteland of natural conditions and large area has Beneficial to the development of photovoltaic generation, but generate electricity and can dissolve nearby, it is necessary to be delivered to east heavily populated area.By power Transmission The influence dissolved, west area abandons light, abandons electrical phenomena seriously, and the eastern region density of population is big, economically developed, to the need of electric power Ask vigorous, the electric energy of photovoltaic generation can dissolve herein.But eastern region shortage of land resource, substantially by farmland, mountain forest, water Storehouse, rivers and lakes etc. are constituted, and develop photovoltaic generation in eastern region by Land Resources Management and the serious restriction of policy.
Therefore, save the area protect green ecological, do not change land status keep land function, do not influence agricultural production On the basis of increasing income, using eastern region farming land installation photovoltaic component, with very great value.
