Did you consider buying a larger freezer (or sacrificing space), and just filling part of it with freezer gel packs? I wonder what the cost/benefit calculation

Did you consider buying a larger freezer (or sacrificing space), and just filling part of it with freezer gel packs?
I wonder what the cost/benefit calculation is for that v.s. an entire solar backup system.

- avar 2y agoYes, you can DIY-it, although I'm a bigger fan of using box-shaped freezer-certified tupperware, it's more space-efficient. But the commercial product is cheap enough to buy if it's going to be your backup plan.
