Frequently Asked Questions
How long does it take solar panels to pay for themselves?
Average solar payback period in the US is commonly quoted at 6-10 years, but that figure assumed the federal credit. With no federal tax credit in 2026, a $25,000 system at $1,800/year in savings pays back in about 14 years. Sunny states (California, Arizona, Texas, Florida) have shorter payback periods due to more sunlight hours and higher electricity rates.
What is the federal solar tax credit in 2026?
The federal residential clean energy credit (Section 25D, 30% of system cost) ended for expenditures made after December 31, 2025, so there is no federal credit for a homeowner-owned system installed in 2026. Some state and utility incentives may still apply, so check your local programs.
Does solar increase home value?
Studies show solar panels increase home value by 3-4% on average. A Zillow study found homes with solar sold for 4.1% more. On a $400,000 home that is a $16,400 increase in value. Combined with electricity savings and any state or local incentives, solar is one of the highest-ROI home improvements available. Most states also exempt solar from property tax reassessment.
