Solar Panel Discussions

Can you go solar without the high cost.?

I’ve been working with – 115 watt evergreen Solar Panels, rated 7.62 amps output. I’m starting with one for this experiment to run one motor and alternator setup. I’ve found low amp DC motors, 1.4 no load amps at 3000 rpm to run an alternator that has a 105 amp output at 12 volts dc to charge my battery bank. I know this set up wouldn’t do whole house by itself but Since your output is more than the Solar Panel output itself you can put together multiple units and still keep your costs down. I’ve thought of replacing the DC motor with a battery inverter and ac motor setup but would need more panels because the inverter has a 40 amp input amperage. The idea here is to go solar without the high price of huge arrays. Would like feed back on this, thanks

As soon as you put a load on the DC motor you’ll use up more electricity then you make, sorry.

Way back when, in my science class we had a very small generator and connected to the generator was several small lights and a few switches, anyone could turn the generator when there were no lights on, but with one light it was very hard to turn the generator, with two lights one only the biggest guys could turn it, and no-one could turn it with three lights one. Too many people have turned a generator/alternator with no load on it and think that’s how much energy it takes all the time, but when you want power from it takes more energy.

If what you are wanting to try worked you wouldn’t need the solar panels at all, you would take the power from the batteries to run the DC motor which would turn the alternator and charge the batteries and have power leftover. It’s been tried and it doesn’t work.

The first law of thermodynamics basically states the best you can do is break even.

The second law basically states you can’t even break even.
