There are many home installation types for solar panels and all of them have different levels of performance.
On February 17, 2009, President Obama signed the American Recovery and Reinvestment Act of 2009 into law.
With a significant emphasis on renewable energy technology namely Wind and Solar, employment, and job expansion, the bill improved upon the 2008 tax credit by removing “cost caps”. The tax change allows consumers and small businesses to take a 26% tax credit off the installed cost of a solar installation.
To a home purchasing a solar power system, the reinvestment act will double their credit.
