Comparison of holiday lights and LED street lamps. The festival lamp is a typical photovoltaic power generation system, which is only one aspect of the problem. What is more serious is that it is also a seasonal load that increases with the decrease of solar radiation. From the analysis of the above you can see, every year the winter solstice is the sun radiation, the smallest is solar battery components power, at least a year is the shortest day of the winter solstice, the longest night of, road lighting takes the longest time.
On the design of holiday lights everyone concern right now is the continuous rainy day lighting problem, this problem was relatively are better solved, as long as the increase of battery capacity is ok, if you want to let the winter solstice road lighting indicators meet the requirements of national standard, unless the sacrifice of spring, summer, autumn solar battery components capacity, no choice. The efficiency of the system will be very low.
Battery power, in the sun light efficiency under certain conditions, the influencing factors of solar street lamps use effect and there are many: the intensity of solar radiation, the rationality of the solar cell component Angle, environment temperature, degree of old and new battery (old and new battery charging and power generation efficiency can differ by more than 30%), and so on. It is not accurate to evaluate the effect of solar street lamps before determining these conditions.
