Inflation Reduction Act of 2022 - A Lot Has Changed!

The Inflation Reduction Act extended the 45L credit for homes sold or leased during 2022 with little modification. However, from Jan. 1, 2023 through Dec. 31, 2032, the tax credits significantly jumps to $2,500 with new provisions and requirements or $5,000 if you become Zero Energy Ready.

What Changed Exactly

First, for tax year 2022, nothing changed. Everything stays the same as before. It's still $2,000 for low-rise residential. You can always go back three years and amend your prior year returns and pick up the $2,000 tax credits for units improved in those prior years. If you have not done this, now is the time.

Second, beginning in 2023, the tax credit increased to $2,500 for single family and manufactured homes when constructed according to new standards set by the Inflation Reduction Act.

Zero Energy Ready Homes

What is a DOE Zero Energy Ready Home?

A DOE Zero Energy Ready Home (ZER) is a home that meets all of the criteria found in the DOE Zero Energy Ready Home National Program Requirements.

DOE Zero Energy Ready Homes are verified by a qualified third-party, like Apollo Energies, and are at least 40%-50% more energy efficient than a typical new home.

This generally corresponds to a Home Energy Rating System (HERS) Index Score which are typically in the low to mid-50s, depending on the size of the home and region in which it is built. But a Zero Energy Ready home is set up to accomodate a right-sized solar array, and the conduit is already run for the wiring from the panels to a inverter next to the service panel.

Let us review your plans and right-size your solar array to ensure you reserve enough space on the roof for a solar array, and that the house is using the least amount of enerrgy possible. This way, you'll know you will qualify for the ZER incentives.
