For those who follow the solar industry, sometimes it's important to take a step back and see where the industry stands and how it got where it is today. Below I've compiled some of the most compelling statistics in solar, from the growth of the industry in the U.S. to the cost of companies supplying solar to the market. Just take a look at how far the industry has come.
U.S. solar growth
The U.S. solar industry installed 742 MW of PV in the second quarter of 2012, up 45% sequentially and 116% annually. This is despite the expiration of the 1603 Treasury Grant Program, a policy that allowed solar installers to get a cash grant in lieu of a future tax credit; the industry has now installed 2.85 GW of solar.
The cost to install solar is dropping like a rock
Every quarter the solar industry takes another step toward grid parity in locations around the world, even passing it in some locations.
- According to GTM Research, the cost to install a utility scale solar system has fallen 45.8% since the beginning of 2010 to $2.60 per watt.
- Over the same time frame, residential solar installations have dropped 21.8% to $5.46 per watt.
I bet you didn't know
Corporate America has taken a surprisingly quick liking to solar power in recent years -- the companies installing solar might surprise you. The Solar Energy Industries Association, or SEIA, just released the top 20 corporate users and here are the top five:
- Walmart comes in first with 65 MW installed.
- Costco has installed 38.9 MW.
- Kohl's has 36.5 MW of capacity.
- IKEA has installed solar on 79% of its stores for a total of 21.5 MW of solar.
- Macy's rounds out the top five with 16.2 MW of installed solar.

- $32,453 -- The cost of the average residential solar system in the U.S. The average system was 5.9 kW, and estimates are that third-party financing helped pay for 70%-80% of these installations in major markets like California, Colorado, and Arizona.
- 10.4 cents -- The cost per kW-hr of SunPower's newly signed 100 MW Henrietta Plant in Kings County, California. For a comparison, the average retail cost of electricity in California this year is 15.24 cents per kW-hr.
- 9.2 GW -- The amount of utility scale solar projects under development in the U.S. as of July 15, 2012, according to GTM Research; 27.1 GW are in the pre-contract phase.
What it all means
The falling cost of solar and the growing number of solar installations provide a huge opportunity for those in the space. Ameresco
But, growth hasn't led to financial gains for investors because companies are selling polysilicon, wafers, cells, and modules at close to cost. Three companies I would be wary of are Renesola
