What is Depreciation?

Depreciation simply means the gradual decrease in the value of an asset over time due to factors like everyday wear and tear and obsolescence. Your car depreciates, your furniture depreciates, and yes, even your solar panels depreciate. But here’s the good news: solar panel depreciation works in your favor, helping you recoup your investment and lower your tax bill.

For solar panels, this means the initial investment cost is spread out over its useful life, which is generally considered to be 25-30 years. While solar panels can generate power for decades, depreciation allows you to deduct a portion of the cost from your taxable income each year, offsetting your upfront investment.

Key Terms to Know

  • Depreciable Basis: The starting point for depreciation calculations, which is usually the cost of your solar system minus any tax credits received.
  • Useful Life: The estimated lifespan of your panels, typically around 25-30 years. While solar panels boast a long lifespan, their value depreciates over time due to factors like normal wear and tear, environmental exposure, and potential technological advancements.
  • Depreciation Method: There are two common depreciation methods used for solar panels: Modified Accelerated Cost Recovery System (MACRS) and Straight Line Depreciation. Both methods spread out the cost over the useful life but differ in the rate of deduction.
  • MACRS: The Modified Accelerated Cost Recovery System (MACRS) is the IRS-approved method for depreciating solar panels. It allows you to claim a portion of the cost of your system as a tax deduction over a specific period.
  • Straight-line Depreciation: This method deducts an equal amount of the cost each year over the useful life of the system.
  • ITC: This is the 30% Federal Solar Tax Credit (ITC). ITC reduces your upfront cost but also affects your depreciable basis. You’ll need to adjust your cost basis by half the ITC amount before calculating depreciation.

MACRS: The Depreciation Power Player

The Modified Accelerated Cost Recovery System (MACRS) is the IRS’s chosen method for solar panel depreciation. It lets you deduct a larger portion of the cost in the early years, accelerating your tax savings. 

Why Does Depreciation Matter?

For both homeowners and businesses, solar panel depreciation can be a powerful tool that can:

  • Lower Tax Bills: Claiming depreciation deductions can significantly shrink your tax liability, making your solar investment even more cost-effective.
  • Provide Faster Payback: Solar panels can be expensive up front, but are often a smart long-term investment. By reducing your taxable income, depreciation accelerates the timeline for recouping your initial solar panel investment.
  • Increase Property Value: While depreciation may slightly lower the reported value of your home on paper, the energy savings and environmental benefits often enhance a property’s market value.

Remember: Depreciation isn’t the same as actual cash in your pocket. It’s a tax deduction that lowers your taxable income, not a direct refund.

Considerations for Residential Solar Panel Depreciation

  • Your tax bracket: The bigger your tax bracket, the greater benefit you receive from depreciation deductions. Depending on your income, you can benefit significantly from depreciation deductions, potentially reducing your taxable income and lowering your tax bill.
  • Financing: If you finance your solar panels, only the portion you own is eligible for depreciation.
  • Home value: Depreciation may slightly lower the reported value of your home on paper, but can provide long-term energy savings and a potential increase in buyer interest.

Considerations for Commercial Solar Panel Depreciation

  • MACRS for Businesses: The MACRS schedule for commercial systems is different from residential, often using a 7-year recovery period.
  • Bonus Depreciation: Businesses have access to bonus depreciation, allowing them to write off a larger portion of the system cost in the first year (currently 60% in 2024, decreasing annually).
  • Improved cash flow: By reducing taxable income, depreciation deductions can improve your cash flow, which can potentially free up funds for other investments.
  • State Incentives: Many states offer additional tax credits, rebates, or other incentives for commercial solar power installations.
  • Leasing vs. owning: Leasing solar panels typically doesn’t allow depreciation deductions for businesses.

Frequently Asked Questions

While solar panels typically increase your home value, depreciation can slightly reduce it on paper. However, the long-term energy savings, environmental benefits, and potential increase in buyer interest often outweigh this minor decrease.

For homeowners, the standard depreciation period is 5 years. Businesses can choose between 5-year MACRS or claiming a one-time deduction within limits.

The rate varies depending on the method used, but generally falls within 20-35% per year in the initial years.

No, depreciation and incentives (like tax credits) are separate benefits. You can claim both to maximize your financial savings.

The material and brand of your solar panels can affect their lifespan and potentially their depreciation rate. Consult your installer or financial advisor for specifics.

Since batteries are usually considered part of the overall solar storage system, you can claim them using the same method and timeline as the panels.

Beyond long-term cost savings, solar panels offer numerous environmental benefits like reduced carbon footprint, increased energy independence, and potential property value increase. Installing solar panels can also make your home more attractive to eco-conscious buyers.

Consulting a qualified tax professional is highly recommended, especially if your tax situation is complex or you have specific questions about claiming depreciation on your solar panels. They can help you maximize your tax benefits and ensure compliance with regulations.

The U.S. Department of Energy, the Internal Revenue Service (IRS), and your state’s energy office offer valuable resources and publications on solar energy incentives and tax benefits. Industry associations like the Solar Energy Industries Association (SEIA) also provide comprehensive information and updates on relevant policies and regulations.
