there are often customers and friends asked me this question, in fact, there does not exist very good question, I think this key is inside which is more cost-effective, more cost-effective. For solar street light system, the system itself involves panels power co. , LTD. , from single crystal panels or polycrystalline panels, from the technical point of view of system design is not much difference. Monocrystalline silicon panels and polycrystalline silicon panels as stable, as long service life.

although everyone knows monocrystalline silicon conversion efficiency will conversion efficiency higher than polysilicon, concrete may be around 1%, but the price of single crystal silicon polysilicon expensive than more than 1%. And that the difference of efficiency for street light system, that isn't really. So, the author thinks that, from the Angle of value to consider, or polycrystalline silicon panels as a solar street lamp system of energy acquisition part is better.

in the solar street light system and the use of polycrystalline or single crystal silicon cell, there is a difference is solar street lamps controller set in optically controlled open voltage slightly difference. At dusk, under the condition of same illumination can have difference between two panels open circuit voltage, customers in the application process, please pay attention to distinguish.
