Description
Technical field
The utility model relates to field of photovoltaic power generation, is specifically related to a kind of distributed photovoltaic power generation system supported based on light pole.
Background technology
Solar street light take sunlight as the energy, daytime, solar panel charged a battery, evening, storage battery to be powered use to lamp source, without the need to the pipe installation of complex and expensive, can adjust arbitrarily the layout of light fixture, energy-saving safe is pollution-free, reliable without the need to manual operation working stability, the saving electricity charge are non-maintaining, simultaneously solar street light is a circulation separately, break and entirety does not work without the need to worry as common public lighting circuit.Along with the use of solar street light technology, so solar street light appears at market thereupon.
But in the research and apply LED street lamp of reality, the intrinsic defect of solar LED street lamp cannot be avoided and is also difficult to overcome:
What stand in the breach is this cover with in " energy-conserving and environment-protective " system that is main selling point, itself has the problem of very large resource distribution waste.Because street lamp product has enforceable standard-required, this is comprising " short of electricity rate " index, and it does not allow can to run into as Landscape Lighting product and overcast and rainyly just not to work.So, from Technology design angle, must based on least desirable weather conditions (short season hours of daylight, continuously overcast and rainy etc.) to the collection of the energy and deposit, so, under most service condition, most energy source configuration (solar cell) and electrical storage device are idle, and being not only system cost must remain high, and with will show energy-conservation of system itself with fully utilize theme and also run in the opposite direction.
In addition, some appear in technically fairly simple problem, also need to drop into higher cost in the application of reality to solve, comprise: the first, the problem of centralized management, if do not use electric wiring, realize the important centralized management of street lamp and remote monitoring with regard to being difficult to, but as configured electric wiring again, then not only increase cost, product "
attraction" on meaning weaken again; Second, solar battery life, the life of storage battery and other balancing boom device lifetime are often all lower than the problem in LED life-span, this just brings the long-life that will realize whole system in fact also to need to solve a lot of problem, can produce higher maintenance cost too; 3rd, because system uses direct-flow storage battery, being very easy to stolen, is also the large problem of system so antitheft.Also have the weight issue of the higher solar cell of general setting height(from bottom) to bring in addition and the raising that also can bring cost improved to the capability of anti-wind of lamp stand design, etc. these problems be all solar LED illuminating system the problem that cannot fundamentally solve.
Distributed photovoltaic power generation refers in particular to employing photovoltaic module, solar energy is directly converted to the distributed generation system of electric energy.It is a kind of novel, tool generating with broad prospects for development and comprehensive utilization of energy mode, it is advocated and generates electricity nearby, grid-connected nearby, change nearby, the principle used nearby, effectively can not only improve the energy output of same size photovoltaic plant, also efficiently solve the loss problem of electric power in boosting and long-distance transport simultaneously.But inhabitant distribution formula photovoltaic generation project is also faced with and builds difficult problem at present.
First, the roof relations between ownership and management of enterprises of residential building especially high residential building are unclear, and the disappearance of relevant law causes the power and responsibility of each side (owner, infrastructure management company, Owners Committee etc.) to define quite fuzzy.In realistic cases, the passive attitude that infrastructure management company often takes " the less trouble the better ", does not encourage the resident in compass of competency to build distributed photovoltaic power generation project, even takes various means to be obstructed.
Secondly, because inhabitant distribution formula photovoltaic generation scale of the project is little, complicated condition, situation are different, so mostly is at present that specialized little company (comprising the undertaking type enterprise that some are emerging) carries out relevant business in this field, explores feasible commercialization pattern.But the various policies just put into effect at present, government does not give enough concerns and help for these specialized enterprises, and these have more the difficult effective popularization that also have impact on inhabitant distribution formula photovoltaic generation conversely of small enterprise's existence situation of innovation and vigor.
Again, the O&M problem of inhabitant distribution formula photovoltaic generation is difficult to solve, because China's rural villager House Property is more clear, distributed photovoltaic moves towards rural area, and photovoltaic generation has certain technology content, must technical professional in operation maintenance, peasant oneself cannot safeguard, although some local governments propose photovoltaic poverty alleviation enter ten thousand projects, after photovoltaic poverty alleviation enters ten thousand, how O&M has become a large problem, and this will affect the development of distributed photovoltaic.
Known by above describing, all there is certain defect in current optical road lamp and urban residents' distributed photovoltaic power generation, is distributed photovoltaic power generation problem demanding prompt solution, if make full use of existing street lamp resource, carrying out distributed photovoltaic power generation will be a kind of well pattern, have certain prospect.
