It’s been a season of mechanical breakdowns here this winter. The batteries for our solar PV system started acting up this past Fall, and the condition has steadily deteriorated so that now they’re only holding a charge for about a day. Off-grid systems like ours are sized to provide five days of charge without sun in winter, so this is a drop in capacity of 80%—pretty dramatic. We’ve lived with solar for eight years; the golf cart batteries we started off with lasted the full five years they were designed for. So I figured for our next set we were ready for the newer, more powerful, and better batteries that are supposed to last twelve years. They’re now three years old. Then a month ago our laptop suddenly stopped working. The computer tech I took it to was able to save our data, but he said the laptop was beyond repair. I bought another used one on e-bay. Two days ago the 4-wheel drive on my truck stopped working while I was driving up the driveway of a client to deliver a door.
