So I have a couple solar cells off some outdoor yard lights that I replaced with new up to date lights so these were for parts. I know solar panels produce power during light but during no light conditions have the ability to suck power back out of the battery being charged, so a diode must be used…..? What would someone recommend as a high efficiency diode to be used(i think germanium??) or rating or part number. Then do I have this right, my 2 solar panels(2inch X 2inch) can go either in parallel or series as this is only charging and not a direct supply source, will one be better config. than the other? (Parallel or series??). I should be able to solder on the PC board where the NiCad batt wires go…..I’m thinking this is ok because the PC board has a On Off switch and will only allow solar power to flow into battery only, no other components thus having WHILE POWER SWITCH IS IN OFF POSITION AND SUNNY should charge batter.?? Do I have this right or am I missing components. Positve solar wire to positive batt wire negative to negative,

Any diode will do.

But the voltage out of the solar cells must be higher than the battery voltage by a bit before the battery will charge. For example, a 12 volt lead acid battery won’t charge until the voltage gets above 14-15 volts. Add the diode voltage to that.

So you need to find out the voltage needed to charge your batteries, and put enough cells in series to get that voltage. Anything less and they will not charge. I doubt you have enough voltage, even with the cells in series.

socialized energy production grids.
yet keeping the power and control over the energy sector in the very hands of the people who’s hands it not be in anyway.

Tesla was right guys. As was Edison.

Independent renewable energy production systems would halt this koyannisqatsi.

Take power away from those who use it against us and put it in the hands of the people.

I.E. Give it to the people?

Ever feel as if you’re one of the most misunderstood people on the face of the planet? LOL.

Oh well.

So much for true freedom and independence i guess.

More government power, more control over the people, increased energy costs to teach us all to conserve the way Al Gore does-ha ha
