The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications
I did get my sign powered up with batteries and LEDs. It is glorious. I put one on the Glenora site today, the idea is that I will turn it on when I leave at night, and off in the morning when I return. Not sure how long the batteries will last yet. The signs are 32″ x48″. The plastic pieces were about $5, the vinyl cut out prepped to stick on was about $33, the LEDs were about $5 from china, and the batteries to run it another $5, an ongoing expense until there is power on site. You can see the LEDs in this vid.
