LG ESS Home 8 battery tax credits and incentives in 2023
Like many other solar batteries, the LG ESS Home 8 comes with a high upfront cost. Financial incentives, tax credits, and rebates can help offset the price of a solar battery. The most significant tax credit to know about is the Residential Clean Energy Credit (formerly known as the Investment Tax Credit), which offers a 30% credit when you buy solar equipment.
Based on the average cost of the LG ESS Home 8 battery, the federal tax credit could offset the price by between $3,000–$3,600. If you install more than one Home 8 battery module in your solar system, the total price will be greater, as will the savings you incur from the tax credit.
Depending on where you live, you may be eligible for additional solar battery incentives. You can combine state and local incentives with the federal tax credit, increasing the amount you receive when you purchase a solar battery.
