Small Scale DIY Solar Project
« on: March 21, 2022, 12:34:23 AM »
Is anyone else working on projects using junked small panels?
I had a solar powered electric fencer that had stopped working awhile ago. I figured it was the transformer that died, so I took it apart. Sure enough the battery still had power. I put the panel in the sun and was getting voltage from it. It did vary a lot which I thought was weird.
I figured that the garden shed my wife uses to store horse feed could use a light so we're not scrambling around looking for a flash light all the time. I found a rechargeable flashlight I had that never worked so I pulled that apart to use the light.
I wired the battery to the light tonight and got it working nice and bright, but the switch was broken and wouldn't shut off, so I need to figure out another switch. I'm also concerned that the battery voltage might be too high for the light. I saw some smoke but couldn't tell exactly where it was coming from. Nothing felt hot, so I figured it was because the light had never been used. Either way, I'll make sure there's nothing flammable near the light when I first use my contraption.

No one believes the theory except the one who developed it. Everyone believes the experiment except the one who ran it.

That's pretty impressive. 36 Volts should power an electric fencer pretty nicely and no need to run an extension cord.
