Solar's declining costs good news for consumers

It is becoming easier for individuals and businesses to tap into renewable energy and reduce dependence on coal-fired plants as national average prices for solar systems drop in the U.S.
Solar system costs have been declining thanks to cheaper installation rates and lower module prices, according to a Lawrence Berkeley National Laboratory study.
The study shows solar system prices dropping more than 30 percent in the U.S. between 1998 and 2008. The most significant drop has been in the prices of small, residential photovoltaic (PV) solar systems.
