With panel prices hitting record lows and performance of projects steadily improving, solar photovoltaics have become increasingly attractive to large investors. Investment in solar has surged to unprecedented levels due to interest from large Wall Street banks, investors like Warren Buffett, and technology firms like Google.
In 2011, the solar PV industry brought in $93 billion in revenues globally, raising $8 billion in corporate equity and debt. That’s a 12% increase over 2010, according to NPD Solarbuzz.
In the U.S., the value of solar PV installations grew from $5 billion in 2010 to $8.4 billion in 2011, according to analysis from GTM Research. Much of that increase came from the installation of large projects. Last year, there were 28 individual projects that amounted to more than 10 MW a piece, up from only two in 2009.
