Solar LED Street Light---Solar Panel
• The low iron tempered suede toughened glass,in the wavelength
range of solar cell spectral response,light transmittance of 91% or
• TPT laminated material is special, the transmission rate is high,
the fight against superior performance,UV resistance, resistance tp
• Exquisite assembly technology, solar panels,the tolerance range
is controlled within 3%, product performance is stable.
• Using high-quality cell, conversion efficiency as high as 17.85%
Solar lamp configuration and working principle
◆ Working principle of solar street light system, solar street lamps
use wide born v effect principle of solar cells, solar cells absorb
solar energy during the photon energy during the day the energy
generated by the controller to the battery charging,
◆ when night falls or around the lamps and lanterns lighting level is
low, battery to provide power to the dc light load.
◆ Dc controller can be in any case, including the sunny or rainy
weather for a long time, can ensure that the battery is not
destroyed, because a charge or discharge at the same time, optical,
acoustic, temperature compensation, and lightning protection,
reverse polarity protection function.
◆ As shown in figure 1. Solar lamps are made up of several parts:
solar panels, solar panels, batteries, lights, lamps and fixtures.
