Solar Charged Lawn Mower | ||||||||

Solar charging station |
After the mower was assembled and ready to go I needed a way to charge it. A used a 11 Watt Uni-solar panel that plugs into the mower when not in use. This panel is made to charge a 12V battery at .62 amps in full sun. I screwed a couple 4' long 2x4s to three cross supports to serve as a mount for the panel (see top left picture). This makes for a light portable sturdy structure. I needed something I could easily move to the best solar access. |

I also mounted a Morningstar SunGuard charge controller on to one of the cross supports. It is hidden behind the solar panel to protect it from the weather. (see bottom left picture) (click to see parts and cost list)

Conclusion | |
Although this solar panel is able to charge the battery I would have liked to get a larger one (if I had the money). As stated on the Home Page it takes about 40 hours of direct sunlight to charge the battery from 50%. Here in Humboldt County direct sunlight is not always prevalent. In optimal conditions we may get 5 hours a day in the winter. This means it would take eight days to charge the battery from 50% to 100%. On the bright side, the grass can't be cut when it's raining and it is usually raining if it is not sunny in the Pacific Northwest. | |
