Compared with the traditional street lamp, solar street lamp is very large, the advantages of but no one is perfect, as well as solar street lamps, it is not perfect, so the shortcomings of the solar street light? Disadvantages: high cost of a single cost very ordinary solar street lamp,
compared with the traditional street lamp, solar street light [ Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 The advantage of very large, but no one is perfect, solar street light, too, it is not perfect, so the shortcomings of the solar street light? One disadvantage: cost higher light very ordinary solar street lamp, configuration down to nearly two thousand yuan, mainly in the solar system, above include solar panels, 【 Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 【, solar battery, solar street lamp controller Used in solar photovoltaic systems, solar controller it full solar charge and discharge controller, coordinate the efforts of solar panels, battery, load, is a very important component in pv systems. 】 This 3 big. The cost of the same power of lamp, solar street light is about 2 - ordinary street lamp 4 times the left and right sides. Disadvantages. 2: the energy conversion efficiency is low while the cost price is higher, but the price is high, not necessarily the quality is very good also. The conversion efficiency of solar panels is relatively low. In theory, monocrystalline silicon solar panels 【 Monocrystalline silicon solar panels with high conversion efficiency of single crystal silicon cell according to the different way of string, and array constitute the components of the body. 】 Conversion efficiency can reach more than 25%, but after the actual installation, may be the reason such as the building block, causing the conversion rate' Conversion turnover thewire, turnover rate in a certain community, community and ecosystem, standing crop ( Individual number or biomass) Are in a stable, input amount in the agreed upon period of time ( Or output) On the ratio of standing crop called conversion rate. 】 Only 15% - 19% or even lower. Faults. 3: are susceptible to interference due to is to use the principle of solar energy into electricity, installation of climate conditions directly affect the battery and solar street lamps use. Such as local solar radiation, atmospheric dust, continuous rainy days, if can't absorb enough energy for a long time, it is possible without lights, worse, long-term work under abnormal amount of power, increase the service life of the reduced speed. Shortcomings four: photosynthetic efficiency range narrow, uneven illumination of the current domestic production of form a complete set of LED lighting' 领导( LightingEmittingDiode) That is led lighting, lighting is a solid light-emitting semiconductor devices. 】 Lamps and lanterns, the emergence of more or less light range is too narrow, the phenomenon of illumination is not homogeneous, technology is not mature enough. If the introduction of foreign advanced lighting lamps and lanterns, its price is more expensive, and the effort, so there is still a unsolved problem.
