Anyways, I'm mining on solar 24/7 with no grid power at all, it's all about calculations, assuming your rig needs only 1000 watt power I suggest going for 3000 watts solar panel, why? You will be able to mine when sun is up and also charge your battery backup for when the sun goes down, I'm running this 24/7 and it works

Do some math, get more solar panels and enough battery bank that will last you from when sun is down to the next day when sun will be up, remember, the more the panels the better
