I have a HF solar 45 watt configured to keep 2- 125Ah marine batteries charged up at 24v.
Its paid for its self just by being there for a back up to my freezer when power goes out.
I hate shopping so I take the wife once a month to stock up on food.
Without knowing I have a system ready for emergencies, I don't think Id go the route I do.
Just the comfort level of knowing my emergency back up is always ready, is worth the small investment to me.
I consider its paid for its self over the last 2 1/2 years just in gas money to town. (25 miles one way for a decent grocery store)
Plus, my system powers my 12x20 barn where I do most all my RE projects. I run all hand tools, saws, drill press ect to exercise the batteries.
Heck, just the fun of it is worth what I paid for it all.
