Frequently Asked questions

Solar Tax Credit
What is the Federal Solar Tax Credit?
The Federal Solar Tax Credit, officially known as the Investment Tax Credit (ITC), is a U.S. government incentive that allows homeowners and businesses to deduct a percentage of the cost of installing a solar energy system from their federal taxes.
Is there a cap for the Federal Solar Tax Credit?
No, there’s no income limit for claiming the federal solar tax credit, or RCEC. Your eligibility depends on the type of solar equipment you purchase and whether it’s installed on a residential or business property—not your annual income. So, homeowners of any income level can claim the RCEC for qualifying solar panel systems and related equipment.
Does Solar Tax Credit apply for Battery Storage or just only for Solar Panels?
Yes, the federal solar tax credit applies to solar panels and battery storage, so you can save 30% on the cost of a new solar plus battery system.
Is the Federal Solar Tax Credit refundable?
Yes, this is a nonrefundable credit — it reduces what you owe but doesn’t provide a refund if your tax liability is zero.
Can I carry over my unused Solar Tax Credit?
Yes! The unused portion of the solar tax credit can typically be carried forward to future tax years, as long as the credit is still in effect.
Does the Solar Tax Credit apply for the upgraded solar system?
Yes, the Federal Solar Tax Credit (ITC) can apply to upgrades to an existing solar system, but only under specific conditions. The current tax credit allows you to claim 30% of the total cost of the additions, including equipment and installation. For instance, if your new panels or battery cost $10,000, you could claim a $3,000 tax credit, substantially lowering your investment.
The IRS generally treats a system expansion or major upgrade as a new installation for tax purposes, meaning:
- The costs of the new components (panels, batteries, inverters, labor, etc.) are eligible.
- Only the new costs can be claimed — you can’t retroactively claim the credit on the original system if you didn’t already.
Can NPO (non-profit organization) claim the Solar Tax Credit?
Nonprofits Can Now Benefit from Clean Energy Tax Credits through a provision known as Direct Pay.
Is Solar Tax Credit still available in 2025?
The federal solar tax credit is currently set at 30% for systems installed in 2025, following the schedule established by the Inflation Reduction Act of 2022. However, under the proposed 2025 Reconciliation Bill, Congress is considering ending the tax credit after December 31, 2025. If the bill passes, systems installed before the end of 2025 would still qualify for the full 30% credit, but those installed starting in 2026 would no longer be eligible for any federal solar tax credit.
Financing & Leasing Solar Panels
Is a solar lease transferable when selling a house?
Yes, a solar lease is often transferable when selling a house, but it depends on the lease agreement and the solar company’s policies. You can contact Eco Solar USA to consult about your solar lease when selling your property.
Installation & Maintenance
Can solar panels be installed on old roofs?
Yes, it’s possible to install solar panels on an old roof. However, you should first have your roof inspected to assess its condition. Be sure to consult with your solar installer beforehand to avoid any potential damage.
