You can still order cheap panels and batteries online in the USA. DIY = freedom
I didn’t read the article, but to back up what the headline says I have seen the price of batteries dramatically decrease over the last few years. For example, about 3 years ago I got some 200Ah lead gel-type batteries for my solar setup that cost over $400 each, and one of them is already failing. Last year and this year I bought LiFePO4 batteries that are higher capacity for less than the lead ones cost. The first batch was near $400 each for 300Ah LiFePO4 batteries, and this year I got more of the same for about $250 each. Lead is dead for solar. LiFePO4 is very cheap relatively now. The next step is probably Sodium-ion batteries - should be cheaper and more reliable than LiFePO4 batteries.











The usual junk markets like Amazon, eBay, AlliExpress. There are probably better places to shop but I just found deals and bought some without much planning involved.
