How would you “plug-in” a solar cell to your house?
I have read about these diy solar cells, blah, blah. But how would you use one to realistically run the appliances in a home? And how would they make the electricity meter run backwards?
A solar cell produces dc voltage. The mains is ac. Anything connected to generate back to the mains has to be synchronized with the mains (ac waveform at same frequency and period)
To connect what you are suggesting requires an inverter (converts dc to ac) that is suitable for synchronizing with the mains. They are commercially available along with the solar arrays.
If your net load is less than what you generate, then power will go back to the grid. You need to get confirmation from your power supplier before you go trying to connect anything like this but its quite feasible. Very expensive, but feasible
