SOLAR STREET LIGHTS SOLUTION
Thanks to solar technology mankinds are free to take advantages of the sun, but we should know the averaged insolation on different horuzontal surfaces are quite different. For a professional solution provider, the solar energy resource must be considered, for instance, a project located in Corsica, France, there is a countryside road needs 60Watts Modularized Solar Street Lights, automatically turn on and off from dusk to dawn, by this requirement we need to check project site solar energy condition first, as follows:
Project site geographical coordinates
The Latitude: 40°9′N
The Longitude: 9°5′
Parameters for Sizing and Pointing of Solar Panels and for Solar Thermal Applications:
Monthly Averaged Insolation Incident On A Horizontal Surface (kWh/m2/day)
22 Years Average
In the last 22 years the average solar radiation in Corsica is 4.21 hours per day, this data will be used for calculating the proper capacity of solar panel.
Battery pack as the power unit is very important for every solar street lights, the LED lights power consumption of whole night will be calculated, and should consider No Sun days such as rainy, swony and cloudy days. The weather condition of project site as follows:
Parameters for Sizing Battery or other Energy-storage Systems:
Equivalent Number Of NO-SUN Or BLACK Days (days)
When design the capacity of battery the backup days should be at least 3.35+1 days, maximum 5.14+1 days, so that the lighting hours in seasons such as winter and spring can be guaranteed, otherwise the solar lights might go off in the middle of night, which will cause inconvenience to traffic and pedestrian.
After our engineer team confirmed the power and model of solar street lights, we can provide DiaLux simulation for customers' project upon per requests, we can design a road to demonstrate, or use the drawings ( PDF or DWG file, etc ) customer provides to do implantation, customers can get a general ideal about our solar street lights working performance before procurement; At same time we will provide our opinion based on years of knowledge and experience, help customers to get the most suitable model for his project, this ensures each of our customers won't overpay money for oversized solar street lights.
