PV Economics:

With the increase in the popularity of PV systems the cost will drop. Due to better manufacturing techniques and increased market demand, solar cells now cost about one-seventh of what they cost in 1980 (Wolcott, 1999).

If environmental, future energy needs, and its long term reliability are factored into the cost, then PV power becomes more competitive with main stream sources (Fies, 2001).

PV greatest economic benefit is as a hedge against future energy cost (Fies, 2001).
