Introduction: Solar Outdoor Light Setup With Old Car Batteries
i have setup an solar system with old car batteries to cut down the electricity bill see the video for full setup and overview
Step 1: Used 110watts Solar Panel
Kaneka's new hybrid amorphous-silicon solar panels generated watt-power is approximately same as that of other crystalline silicon solar modules during the winter, but in summer the Kaneka Hybrid generates more power compared to many other crystalline silicon PVs. The combination of thin-film polycrystalline silicon and amorphous silicon help to "trap" light and offer improved conversion efficiency. These solar panels also use a lead-free solder..
Step 2: Pwm Solar Charge Controller 10amps
this is cheap but effect solar charge controller for now. i future will change it to a pttm solar charge controller
Step 3: Old Restored Car Bateries
i got around 10 batteries from the junkyard 6 of them restore to good contion
Step 4: 12 Volt LED Lights
no power invertors were used as it itself consume some energy. So lights are connected directly to the batteries.
Step 5: Timer and the Control Panel
the LED lights are turned on and off via timer. in future in will be changed to an light sensor
Step 6: Money Saved With This Setup
this is my home free energy solar setup to power led light around the house.
Total cost of this project 500AED = 130$
Electricity bill saved per month 200AED = 55$
