Cheap solar panels

with one comment

I mentioned recently that CBC news story about the couple with solar panels on their roof. The problem up until now has been that technology has been expensive. Sunlight is free but converting it into electricity came in at around $3 per watt. Now a company in California has come up with a way to do the same job for 30c a watt.
