Solar cell can pay for itself
I live in Quebec.
I was calculating to see how much energy one of those garden lights can produce, how long does it take to charge a AA battery with it, how long does
it last when powering the LED, etc.
Mine can make 4.29$ worth of electricity in 1 year, if there was sunlight 24 h a day (never mind the fact that it varies by hour and also by season).
I estimate that in reality, it can make 1$ per year. Which means that it can pay for itself in 3 years.
Anyone considered having a large solar panel or 2 at home?
During winter, I could use the electricity for heating. I don't need converters and batteries.

We must attach the electrodes of knowledge to the nipples of ignorance and give a few good jolts.
Yes my evolutionary friends. We are all homos here. |

Thousands of people do this! I don't know if they've calculated if they pay for themselves, though! It would be interesting to find out just how long
it would take to start profiting.
Good eyes
