How did solar PV rebates begin in Colorado?*

In recent years more and more Coloradoans' have begun demanding clean renewable energy. In November of 2004, Colorado voters planted the seeds of a Colorado industry that would grow by more 1,000% in its first few years when they passed Amendment 37.

Colorado Amendment 37

Amendment 37 (A37) mandated that Colorado utilities with more than 40,000 customers generate 10% of their electricity from renewable sources by the year 2015. In addition, it required that 4% of the initial 10% generation come from solar. The rules were finalized in the spring of 2006 and Xcel began issuing solar rebates. A37 is something that the citizens of Colorado can all be proud of as it was the first voter-initiated renewable energy legislation is the U.S., and has played a large part establishing a sustainable renewable energy industry in Colorado!

Colorado House Bill 1281

Governor Bill Ritter was elected to lead Colorado in 2006, after running on a platform that promised to bring more renewable energy to Colorado. In early 2007 Governor Ritter signed into law House Bill 1281 (HB1281) and effectively doubled the original goals of A37 to produce 20% of Colorado's electricity using renewable energy by 2020.

30% Federal Tax Incentive

As part of the 2008 Emergency Economic Stabilization Act, the 30-percent federal investment tax credit has been extended for both residential and commercial solar installations for 8 years (2009-2016). The legislation improves upon the previous 2005 Energy Bill by allowing Alternative Minimum Tax (AMT) filers to take the tax credits and by removing the $2,000 cap for residential solar PV system. We strongly recommend that you contact a professional tax advisor to inquire about your specific situation, when purchasing a solar PV system.
