I made a set of small solar gadgets which included a USB powerpack, solar capable radios and a rechargeable flashlight. I made some improvement to my powerpack by adding another small solar panel. I tried to add a charging indicator light but for some reason, the zener diode with the 5.6v breakdown voltage didn’t work at that voltage. I will research this and come up with a fix.

Contact Johnny Valentine at Gain Solar Services for all questions. http://www.gainsolarservices.com/ Gain Solar Services is our solar contractor for all of the homes we design and build. Hybrid Solar System – 6kw ground mounted solar system with battery backup and grid interactive. One of the very best solar systems in my opinion….taking your home off-grid if needed, but using the grid as long as it is available.
