Take Advantage of the Federal Tax Credit Program on the purchase of your Solar System along with the optional purchase of new batteries with your solar system. 30% of the cost of equipment that uses solar energy to generate electricity is a tax credit; below is the paragraph taken from the Instructions for IRS Form 3468:
Section: Line 5b and Line 11b - Enter the basis of any property using solar energy placed in service during the tax year. There are two types of property. 1. Equipment that uses solar energy to illuminate the inside of a structure using fiber-optic distributed sunlight. 2. Equipment that uses solar energy to: a. Generate electricity, b. Heat or cool (or provide hot water for use in) a structure, or c. Provide solar process heat (but not to heat a swimming pool.) Most Individuals and for profit businesses can use this tax credit (contact your accountant to verify that you can use tax credits.)
Form 5695 is detailed towards Residential Energy Credits
