A typical household system is in the range of 600 to 2,000 watts of panels, which is what that photo appears to be, perhaps 20 100watt panels. Even the larger system would only run a 20 hp motor for an hour or so after a good day of full sunlight and charging, with no other loads connected like those power tools and machinery. The numbers (blah blah blah) are what matters when you are talking about powering a large motor. Assuming that one panel will charge one battery in one day is nonsense. How large is the panel, how large is the battery, how much sunlight hits the site? A typical residential solar system is not big enough for what is needed to mix papercrete unless you are in no hurry. A couple of mixer loads a day will take a long time to make a house. Tripling or quadrupling the size of a solar system would be expensive.
I still think a forklift motor would make a great mixer if it could be powered easily. I don't see it as an advantage over any other kind of mixer from a safety standpoint, or a convenience standpoint. I see disadvantages in the expense, in the huge battery bank that you will have to place next to the mixer or run large expensive cables to. The amperages involved are large and potentially dangerous. A forklift motor may weigh 100 or 150 pounds, not exactly portable by itself even without the batteries and controllers.
I'm starting to repeat myself, so I'll stop. I look forward to your video showing your mixer in operation.

What if someone is planning on powering their entire house from a solar array and batteries when the house is finished? If someone is planning on acquiring those things ANYWAY, why not mount your solar panels on a ground mount and take advantage of your house's future power supply during construction as well? https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj5xF1nztDr9oFjC9w43GwWjF7BuUqILLYh_q6MNGDFm8HeIe3FpWngehTvrc90dW9TYrw__ViLsEVSH93if6uRKdYkLjXYL549-IpTgBAdlUB9-hBMHtNB6ViwzoPsIYqFf-sGK_DbG7vI/s1600/DougPVMts01.JPG The same argument can apply to wind, or any other power source. If you are going to acquire it anyway to power your home, whatever it is, it makes sense to go ahead and get it early and use it to power tools and machinery during the construction of the home. That is just working smarter.
