Solar panels only generate electricity when the sun is shining. To mine continuously, you'll need a reliable energy storage solution, such as batteries, to store excess energy generated during the day for use at night or during cloudy days. Wouldn't it be too expensive?
That is why OP asked everyone here because in my opinion that would be expensive and inefficient if we don't know about batteries One of the problems is corrosion to batteries too. The best way is to do mining like philpma did store electricity in the grid.
I think the best is mining with solar panels during the day and mining using the grid at night at least this method I believe can save electricity.
