Solar power installs almost doubled in 2010

(PhysOrg.com) -- The report for 2010 was released by the Solar Energy Industries Association on the solar markets and installations of the United States, and it revealed that solar power is a growing market.

In the United States 956 worth of all types of solar power were installed in 2010. That gave a cumulative installed capacity of 2.6 and while this may sound like a lot of solar power it is only enough to power about 500,000 homes, and it represents less than one percent of all of the installed capacity in the country.

Despite the relative scale of the contribution, this growth is still fairly impressive. When you compare it to numbers from the same report in 2009, the total value of solar installations was only $3.6 billion. In 2010 that total just about $6 billion. We can see that the capacity in dollar value almost doubled. Though not all solar sectors showed growth. One shrink of note was in the US's share of photovoltaic installations, which slipped to 5 percent of the world's total, down from 6.5 percent in 2009.

The reports also show that some states that are doing better on the conversion to solar power than others. California did the most in cumulative capacity of solar installations. Other states with notable cumulative capacity of solar installations include New Jersey, Florida, Arizona, Nevada, Colorado and Pennsylvania, which between them accounted for 76 percent of the solar capacity installed in 2010.

There are no predictions as to whether or not this trend will continue in 2011. Though, there is an industry wide goal of powering 2 million homes with by 2015.

It's enough to power exactly zero homes when the sun is not up.

Stop making comparisons about powering homes by the amount of energy the renewables produce on average. Average power doesn't cook my food or heat my water - it's just a damn lie.

Try using a solar hot water system if you want positive results heating your water except for very cold days.

Good thing there are all kinds of way to store energy.

Just waiting on Solar-Tidal Farm Arrays

I'm glad they ARE moving toward other sources of power, so long as we don't just burn our bridges while oil is still available at the price it is. (Obviously not including this current high spike due to the unrest in the Middle East, that's an artificial event not related to the actual availability of oil.)

I really look forward to the day when energy is as cheap and abundant on Earth as it is in space.

What are you talking about? If you average the results of solar panels across the rage of the current United States electrical grid you'll be fine. Anyways it is supplemental, solar energy produced human life. Get over it. It is the future.

Ask yourself, as I am asking you: Where are you getting the knowledge to justify your position/comment? Please be very careful not to form your own opinion from the opinion of others.

I am waiting impatiently for better efficiency of solar pannels - 50% and higher

Maybe then we will see faster growth

There are no energy sources that even approach a 50% end to end efficiency.
