Solar Panels Reach $1 a Watt
ZosX writes "An article over at Popular Mechanics announces that, for the first time, solar cells have been manufactured for the much sought-after figure of $1/Watt. They also talk about a new study of the cost of the particular raw materials used in different manufacturing processes. The conclusion is that the company that just achieved the $1/W milestone, using cadmium telluride technology, may not prove to be the long-term winner capable of meeting demand when it rises into the terawatt range."
I stand corrected. Should have done a little googling.
The fact remains that most of our infrasructure is AC, and it's not going to be replaced by DC in our lifetimes.
Okay so I use 40 kilowatts per day. That works out to about $5 per day. So I'd have to have a $40,000 solar system which works out to about 21 years to pay it off. Unless I'm missing something, this make no sense at all. Probably why it's only economically feasible for the individual with massive government subsidy. Such was the case in the 70s. Once the subsidy evaporated, so did the solar industry.
