I'm in the US and it's showing a 100W panel for USD 37.21 (free shipping, including tariffs but not state/local taxes).

Also the panels Carter installed were solar water heaters - in 1979 solar photovoltaics were just starting to expand beyond satellites and cost like $40/watt.



it's actually $33 because there's a $4 coupon available to everyone on the page

and if you buy 2 at a time there are multiple 10% codes available

so it's $67 USD for 200watts

100watt 18volt 5amp panels that can be put in series or parallel

for $33 each, it's crazy
