The federal government currently offers a 30% solar tax credit. It is important to note that as a renewable energy credit, and not a deduction, you will receive the 30% back on your federal taxes (until 2021). Additionally, commercial customers can take a 5-year accelerated tax depreciation on their system cost.
Customers who lease solar panel systems cannot claim the federal tax credit outright, but the benefits are passed to them from the system’s owner or installer, lowering their monthly payment substantially.
