No matter how you look at this, the total installed cost of solar systems are going to continuously drop at a significant rate for several years. We are no where near the end of innovation in solar components.
In was only last year, 2008, that micro invertors for solar came on the market. These allow conversion of DC to AC for each solar panel, making the overall system more efficient by eliminating the bad ripple effect that one shaded or dirty solar panel can have on the rest of the system. Some solar companies are integrating these into their solar panels making installation simpler, quicker, and cheaper.
