How much money a solar street lamps controller

Nowadays more and more widely popularization of solar street lights, but not all of the area is fit for the development of solar street lamps, so what is hindered the development of solar street light? One, not only the high cost, limited by natural factors influence too much now the sun

the current solar energy lamp is blossoming becomes more and more common, but it is not a certain area is suitable the development trend of solar energy lamp, then what is blocked the development trend of solar energy lamp?

a, engineering to build high value, not only by natural factors endangering the limit too much

at this stage in the application of solar energy lamp also has 2 is not enough, because of its high value of engineering building, one-time investment is large, it is in the marketing promotion of the common problems encountered during the whole process; Second, the solar power as a kind of electric energy, of course, ultimately to the natural factors such as sunlight, temperature limits, which to a certain level hampering the development trend of solar lamp.

2, narrow sunlight category

because of solar lamp light intensity category for 6 - 7 meters, beyond 7 meters will be gloomy, not quite suitable for the tunnel construction, big city section of the regions with relatively high sunlight regulation, at present the key for the narrow two-lane road.

3, difficult to achieve economies of scale

if the solar power station more understanding, you will understand the solar power generation solar panels often can convert the sun's light energy to electromagnetic energy, the conversion of the solar panels is critical. Solar power generation solar panels at present stage there are two, a photovoltaic cell and single crystal silicon, a conversion rate than behind a front, but wins in high cost performance. But this kind of company are all imported raw materials to carry out overseas assembling, can be in China's independent monocrystalline silicon photovoltaic cells and solar panels manufacturing company basically no, China's photovoltaic battery company wide scale is small, it is difficult to achieve economies of scale.
