The Shine On Solar edition of the CEPGI provides an indication of the trends in innovative activity in the Solar energy sector. Victor Cardona, Co-chair of the firm’s Cleantech Group stated, "Solar patents are now second only to Fuel Cell patents among clean energy technologies. Solar Photovoltaic patents spiked in 2009 to a best showing since 2003 with third generation solar PV patents topping the other technologies. Samsung led the other Solar PV contenders during 2009 and early 2010 pushing aside overall PV leader Canon. Solar thermal patents were granted to 22 separate entities with none even receiving two patents and Wal-mart Stores being the only household name among the 22.”
