Practical Solar Power

Due to insurance considerations, we are a 3-car household in a 2-car house. One car has a manual transmission, and nobody likes to drive it, so it gets to sit in the street. The car is in a decent shape and runs fine, but once we stopped driving it, its battery started to lose charge. It took about 6 months for it to discharge completely.

I installed a solar element (see the picture), and plugged it into the cigarete lighter outlet. In a month or so, it recovered the battery and now I can start the car again without any concerns.

So, this thing is not a snake oil. Good to know.
