Light pollution
فروردین ۱۷, ۱۴۰۰Principles of urban lighting
فروردین ۱۷, ۱۴۰۰The creation of light and illumination by solar systems has many advantages and, of course, several disadvantages.
Undoubtedly, when using renewable sources such as solar panel and solar lamp base, we will not need fuel, the lack of a national electricity network is not an obstacle, it will not be harmed due to environmental compatibility, the problem of noise pollution is eliminated. It also does not need water to generate electricity and, most importantly, will not pay for electricity; But in addition to these benefits, there is a high initial investment cost and dependence on changes in solar radiation during different days and months of the year. Therefore, it is obvious that if we overcome these two categories, or in other words, we have a valuable and profitable investment in the long run.
Solar lighting systems usually consist of several parts, including: solar panel, battery, battery charge controller, light source, box or box in which the battery and other accessories are placed, solar lamp base and base foundation. Naturally, each of these components can affect the lifespan and price of the set.
A solar panel consists of assembling or placing solar cells side by side. The solar panel converts photon packets into electrical energy. Due to the production of panels from semiconductor compounds and the conversion of radiant energy into electricity, these panels are called photovoltaic or solar. Which are divided into three categories:
Polycrystalline panel
Monocrystalline panel
Tape panel
In some advanced solar panels, every 3 to 4 meters, the solar panel produces 2 kilowatts of energy; But at the base of street lights where the light source is usually COB, SMD and LED projectors 20 watts, 30 watts, 40 watts and 60 watts; 80, 100, 120 and 160 watt solar panels are used. Definitely, the larger the panel and projector, the higher the battery amp and charge controller.
Types of tubular and multifaceted bases with appropriate thicknesses and heights, are necessary to complete the base of solar lights and finally to provide and prepare a suitable foundation for their installation on the ground.
