Discover the 5-year IRS depreciation life for solar panels. Solar energy systems installed for business or investment purposes qualify as depreciable property under the Internal Revenue Service (IRS) code. This accelerated depreciation method enables property owners to recover their investment more quickly compared. . The OBBB signed into law by President Trump on July 4, 2025, fundamentally alters the depreciation landscape for solar energy systems. The legislation eliminates a long-standing favorable depreciation treatment while simultaneously restoring another powerful depreciation benefit. This means you can spread the cost of your solar system over five years, claiming depreciation deductions. . The Modified Accelerated Cost Recovery System (MACRS), established in 1986, is a method of depreciation in which a business' investments in certain tangible property are recovered, for tax purposes, over a specified time period through annual deductions.
