The battery bank on my solar electric system finally died over the winter while we were away. That came as no surprise as the batteries were pretty much shot last fall. However, ten years is a pretty good run for flooded lead acid batteries.
I was thinking of putting off buying new ones, but changed my mind. While it's tempting to pay down debt, it makes no sense to pay higher electric bills either. Buying batteries and getting the system up and running again is a good return on investment.
Battery development has been rapid in recent years. My hope was that they'd be economical for my storage needs. It turns out that good old fashioned lead acid is still the best bargain. While lightweight lithium batteries make sense in cars, light weight isn't necessary for a house. The only time when the weight of the house batteries matters is when they are installed. After that they just sit there.
Getting the solar electric system up and running makes sense economically, but it's more important to have them for grid down situations. Storms in the mountains still knock out power often enough to be a pain. Only makes sense to concentrate on getting the system sorted out once more.
