Why solar LED street lighting fail to work in few months?
In todays market many manufacturers manufactur solar LED street lighting systems at cheap pricing by providing MS pole, MS powder coated battery boxes, speaker wires with luminary and DC to DC converters in place of LED drivers , SMF batteries (not recommended in solar application)and cheap manufactured solar panels.The result shows withing 3 to 4 months with many failures like changing colour of LEDs or LED flickring or few LEDs burnt , battery gravity low due to improper charging unit and solar panel.Lastly noone picks the phone after installation which is the most negative aspect in non professionals solar industry
We always get enquires about solar street lighting for repairing and maintenance and successfully replaced with ours at many places in Northren region of India.
Why solar power pack fails to work after few months ?
The same story is in case of solar power packs ,we have seen many clients who are interested to install solar power pack but they install from the installer who quotes low price and when the system is actually installed, the system fails to work due to many reasons the main question is WHY?
WHY? because they have not designed the system according to the load requirements ,installation of local batteries, local charge controllers , local day and night switch by using relay , aluminium wires insted of copper wires, under sized cables for interconnecting panels ,charge controllers and interconnecting batteries, loose connections by wrapping cables with insulation tape etc.
Now a days we receive many enquires about system failure ,when we actually visit the site and come to know what people are doing at sites to earn money.They install solar panels of low quality and under wattage panels and paste stickers of a good brand and with more wattage to show the clients.They use MS structure for mounting panels and nothing to do with the angle and direction of the panels.They use aluminium wires from solar array to charging unit or solar PCU,the most worst thing is controlling unit (local make) fitted in a stabalizer body which not only reduce the life of battery bank but damaged and even permantly dead the solar panels.
