The price of solar photovoltaic power systems (solar panels) has fallen substantially in the United States throughout 2011 and 2012, according to a new report. The average price of residential and commercial photovoltaic systems in 2011 fell as much as 11-14% from the year before.
The report, issued by the Department of Energyâ€™s Lawrence Berkeley National Laboratory, also found that California prices dropped an additional 3-7% during the first half of 2012.
In 2011, the average installed price of photovoltaic systems was $6.10 per watt for systems less than 10 kilowatts in size, and $4.90 per watt for larger systems of 100 kilowatts or more in size. Those larger than 2,000 kilowatts in size averaged about $3.40 per watt. Today, the prices are even lower, and the report authors believe they will continue to drop due to large-scale deployment programs and other factors.
The downside to this is that the incentives for solar power have dropped as well, by as much as 80% over the past ten years. This might sound like a bad thing, but if prices for solar power continue to drop, customers may need nothing more than a drop in electricity costs as incentive to take the plunge.
Do you think this will lead to an increase in residential and commercial solar energy investments?
