The disadvantage of solar street lamps in shandong

Suzhou the shortcomings of a disadvantage: solar street lamps 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 battery, solar street lamp controller, these three



suzhou [solar street lamps 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 shortcomings of a 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.
