I fallow the three R rules of living green; Reduce, Reuse and Recycle, as well as I try to find sources of renewable resources.
To achieve this goal I salvage many things from the garbage and one of the things I salvage from the garbage is solar garden lights.
Solar garden lights can be so inexpensive to buy people don’t repair them when they stop working; they just throw them in the garbage when they stop working and this is where I step in.
By salvaging the solar lights from the garbage I reduce the waste going to the landfill, R1.
By repairing the lights I reuse them R2.
And by stripping for the good parts and recycling the other materials, R3.
With solar lights and the solar cells you get a renewable resource, solar energy.
In this Instructable I will be sharing the special trick use for repairing solar cells.
Step 1: Attaching New Leads to a Solar Cell
The most common repair to a solar light is replacing the battery with a rechargeable battery (Not a disposable battery,) please. Replacing the battery with a disposable battery is a mistake I see in many of the solar lights I salvage.
The next most common defect is oxidized wires and the hardest to replace is the leads on the solar cell. Whether by oxidization or breaking while striping the solar light you may need to replace the lead wires to the solar cell and you cannot just solder new leads onto the cell in many cases.
Liquid solder that does not need heat to bond the materials together don’t always conduct electricity however I have found something that does conduct electricity and connects the leads to the solar cell.
It is called “Quick Grid Repair Resin” and it is to repair the rear window defogger in your car, I buy it at the local automotive supply.
