The federal solar tax credit

This tax credit (or investment tax credit) allows customers to pay off their annual IRS bills using up to 30% of their solar installation costs. For example, if your PV system costs $10,000, you can reduce your tax liability by a whopping $3,000. Think of this solar incentive as a one-time gift card from Uncle Sam. It instantly reduces the upfront cost of your PV installation, allowing you to speed up the payback period of your investment.

The net metering program

Available in almost every state, the net metering program allows you to sell excess solar electricity to your local utility company at a profit (usually for credits – not cash). With this special incentive, it's possible to receive $0 or even negative electricity bills every month. Like the tax credit above, net metering helps to speed up the payback period of your solar PV system. Net metering also removes the need to purchase battery storage for your solar installation.

The solar feed-in tariff

Like net metering, feed-in tariffs allow you to monetize your solar electricity. But under this incentive, it's sometimes possible to receive an above-market price for your energy in actual cash (not just credits). You might also be allowed to sell your solar power at above-market rates, making it one of the most lucrative incentives on this list. However, the solar feed-in tariff is not available in all states.

Solar rebate programs

Solar rebates work exactly like rebates for other consumer purchases. You buy a new PV system, mail in a form and receive cash back. It's a very simple strategy for reducing the upfront cost of your installation by 10%, 20% or more. However, each state offers different rebates, so check with your municipality to see the exact type of rebate you can receive for your solar energy system.

An important warning about solar incentives

Receiving free money to go solar is a great feeling – especially when that money comes from the government or local utility. But this free lunch won't last forever. Solar incentives are designed to "incentivize" early adoption. As more people go solar, the benefits get scaled back progressively. This is why the feed-in tariff isn't available in all 50 states. In some regions, solar rebates have disappeared altogether. Even the federal tax credit is set to expire in 2035.
