For people who have high electricity rate i recommend you buy solar panel without battery so you can use mixed power will reduce your electric bill alot.
What country are you in? Probably at the equator, where the sun is constantly shining. In Russia, for example, the payback period for solar panels is more than 6 years. You have free electricity, with such opportunities you can get an excellent profit in mining. How much money did you spend on the purchase of solar panels and the necessary equipment and how much power do you have?
