Hello,
can anyone help out with where I can get solar powered miners.
This is off topic here.
But to answer, I think there is no integrated solar powered miners, or a PSU that is solar. Solar energy is a separate system for your electricity supply that can be grid tied to save electricity bills.
You can buy solar panels connected to an inverter. You may also want to have batteries for electricity storage.
There are threads here that discuss solar energy you may want to read to get more information.
