To restrain the development of solar street lights is the price

Bottleneck restricting the development of solar street lights is the price: currently, restrict the application of solar power price is one of the most important link, with a light dual solar street light, for example, two road load sharing is 60 watt, 4 effective light in the middle and lower reaches of the Yangtze river region. 5 h/day, every night

the bottleneck restricting the development of solar street lights is the price: currently restrict the application of solar power is one of the most important part of the price, with a light dual solar street light, for example, LED street lamp, two road load sharing is 60 watt, 4 effective light in the middle and lower reaches of the Yangtze river region. 5 h/day, 7 hours each night discharge, calculate the panels to 20% increase in reserve) The panels will need to about 160 w, 30 yuan per watt calculation, the cost of the panels will be 4800 yuan, plus 180 ah battery costs are at around 1800, the whole street lamp one-time investment cost is much higher than the utility street lamp, caused a major bottleneck in the field of solar street light applications.
