Does “Moore’s Law” hold for Solar Power?

In New Jersey, between 2001 and 2010, we went from a total of six systems with a combined capacity of 9.0 KW to about 7000 systems with a combined capacity of 211,000 KW or 211 MW. This is illustrated below.

This is the “hockey stick” curve of exponential growth typical of positive feedback mechanisms. I expect this kind of growth to continue for the next few years as prices drop, until solar meets 25% to 35% of New Jersey’s needs. This would be another 2500 to 3500 systems and about 200 additional MW in 2011 and 4000 to 5000 systems of 300 to 500 MW in 2012 , and brings me back to “Does ‘Moore’s Law,’ or a corollary, apply to PV Solar?” or “Is this a bubble?” Continue reading →
