« Last post by BillTodd on July 05, 2025, 03:31:00 PM »I've been experimenting with a couple of panels and cheap LA batteries for a couple of years now.
It's currently running my network and freezer (using just over a kWh a day) . I have to split them east & west either side of my roof.
The intention was to see if a cheap dc system could pay for itself in a reasonable time period , which it probably wiill in another year .
However, based on my low electricity usage and the difficulty of using it to capacity, I can't see hard nosed economic argument to keep it nor expand it , even I buy an EV (other than my bikes) and cover the roofs in panels . I simply don't have long enough live
I think anyone thinking about PV as an investment needs to do their sums ... carefully.
