My solar panels are generating 475kw/hr give or take,
The 475kw is my excess after powering my home and charging batteries
There's something wrong with the units you are reporting. I sincerely doubt you have a solar farm producing 475 kilowatt-hours of power unless you've invested about $500,000 into an array farm and have it running on several acres of land. I think you mean you have 475 watts worth of panels, that is much more reasonable (and not enough power for even a single S7.). Maybe you mean you sell and average of 475KW back to the grid per month, also reasonable. But I am confident you do not generate 475,000 watts of excess power per hour.
I think he got the digit in wrong place is my guess. Which is kinda scary went talking about investments and to be so far off. It is something you should know by heart.
If you don't like number crunching figruing best time to mine, best time to sell. You really will not enjoy mining it is a lot of speculation and I love it, but for some they like buying coins and going that route. Which is a not a bad option.
