Why own instead of lease
- You own it. The panels, the battery and every dollar they save are yours — not a company’s.
- Your payment ends. A solar loan gets paid off. A lease or PPA bill runs 20–25 years.
- No yearly price hikes. Leases and PPAs often rise about 3% a year. A fixed-rate loan doesn’t.
- Easier to sell your home. Owned solar transfers like any upgrade — no contract for a buyer to take over.
- You’re in control. Your battery settings, your monitoring, and any electricity plan you choose.
Permits, HOA & incentives
- We handle the city permit and utility approval.
- Texas law stops HOAs from banning solar (Property Code §202.010).
- The added value is exempt from property tax — file Form 50-123 with your appraisal district.
- No federal homeowner credit applies to 2026 purchases.
