“USA Today is running a pretty good article on solar power that gives an overview of the current state of the industry. Highlight include production costs of $1.19/Watt for First Solar, 40% annual cost reductions over the last five years, revenues expected to triple in three years, and a prediction for 2014 as the year when solar photovoltaic power plants become cheaper than other forms of generation. From the piece: ‘Like wind power, solar energy is spotty, working at full capacity an average 20% to 30% of the time. Solar’s big advantage is that it supplies the most electricity midday, when demand peaks. And it can be located at homes and businesses, reducing the need to build pollution-belching power plants and unsightly transmission lines. In states such as California, with high electricity prices and government incentives, solar is already a bargain for some customers. Wal-Mart recently said it’s putting solar panels on more than 20 of its stores in California and Hawaii. Google is blanketing its Mountain View, Calif., headquarters with 9,212 solar panels, enough to light 1,000 homes.'”
$1.19 per watt is INCREDIBLE, since best I could do was about 4.30 a watt. We’re getting to the point where “off the grid” living would be realistic.
