Well here I sit, still not satisfied with my current Solar system.
Could be that I am addicted in some strange way. I am certain that is not the case. At least I think that is not the case. I do love powering things from sunlight.
My most recent system is a true success, it works perfectly for the application I had in mind when
I designed it. Problem is the application has changed in every regard.
Actually this is my third Solar system in the last five years.
The first two systems were related to my fish pond. I have a pond that is 70 feet in diameter and 12 feet deep, needs pumping to keep things healthy.
My latest was for an old portable classroom/office about 1,000 square feet.
I use that space as storage and office space. I wanted to build a system that was capable of running an 8,000 BTU ac for several hours and of course lighting, computer, and my 3d printer.
I did it, works perfectly!.
Problem is we now we use that space as an office/ distribution center where two or three piece workers show up in the evening, not good.
So increasing the batteries is a must,more batteries require more input (more panels).
Batteries are really complex, as least as complex as any other part of the system. Batteries cost a lot are really heavy and don’t last long. (lead acid flooded)
I had hoped to wait for Telsa type battery packs and related components to become common (cheaper) before I did any serious spending on the battery portion of the system.
Right now all I have is four 160 ah 12vdc batteries in series (48vdc).
Not much reserve power when you are trying to run an air conditioner.
I am really excited about converting this system. I maybe more excited about selling it and starting over, bigger, better, more horse power, make that SUN power .
