Great perspective and planning.
But I’m always leery about “warranty” from solar companies, considering all that have come and gone.
Living in a condo, I can’t deploy the hardware you have, but I have some liberals living in the 40-unit complex that I can burn for warmth. Heh.
I am “prepped” w/ food, water, TP, ammo, firearms, cooking and water purification gear etc for 2yrs.
I went with these companies for that reason. Sol-Ark (started 10 years ago by army veterans), Mission Solar (started 9 years ago). Hopefully those are old enough to prove stability as can be expected from solar companies. I thought a lot about getting LG solar panels for that very reason of being a stable enough company to honor a warranty. But opted instead to go with the oldest companies I could find that made their products in the U.S.
