The maintainer circuit.

why this can work?
a solar panel have have 10 % efficency (the best 14%). . The Led will not lightning the fully surface of panel = lost.

If you contruct tha its full lightning. so the light is weaker, and  it hve lost that light  go also outsides of panel.

also the j.t. converter produces losts !!

it is i,possibel to contruct THIS WAY an electronic-optical (light) PERPETUUM.

Only nice experiments to learn the physics.

i have this one tested and working but I am using 2 neon tubes from laptop screen.The light covers a bigger surface of the pannel and it does work indeed. I will make a video and post it on youtube.

I don't know what the light spectrum is from the lap top tubes but when I tried this a couple of years ago, I found that the light band emitted from the leds (white) was not an efficient way to supply energy to the solar panel.  The band was too narrow unlike sunlight.  So, this adds even more to the losses.  I even used mirrors to bounce the light all around the solar cell in a box like configuration and still no good.

I look forward to seeing the video with the lap top tubes.  Maybe using multiple leds of different spectrums, ultraviolet, infared and white might improve this?

Hi bill
I was looking at experimenting with those small radiactive light sources (glow paint etc) and solar but ran into the same spectrum problems. The idea was to have a lightsource that did not need replacing for years and ran 24/7 between a solar cell sandwich. Low power but constant. Trouble was the cost lol.
Would be interesting to get a vell and test different coloured leds and a combination.

Hi bill
you can intensify the light using a fresnel lense. One cell but lots of lights

Hi Stevenrsd1
Thanks for sharing...what type of garden light did you use and can you scetch out a circuit diagram
Kind Regards
