"The 30% federal Investment Tax Credit remains the single most powerful solar incentive in 2026 — but it only applies to systems you own outright (purchase or solar loan). If you're comparing a lease vs. loan, run the numbers on the ITC value first. For most homeowners, ownership beats leasing by $8,000–$15,000 over 25 years. Always get at least 3 quotes and verify NABCEP certification before signing any contract."
