As a business looking to go solar in the US, the best incentives available to you are tax incentives. Between the investment tax credit (ITC)–which works the same for businesses as it does for homeowners–and depreciation benefits at both the state and federal level, you can expect to receive half of what you pay for solar back as tax benefits. While the ITC has been around for a long time, and its success is well documented, bonus depreciation is a newer incentive that can provide nearly as large of a tax benefit as the ITC.
