What Affects Your Solar Cost?
Roof factors:
- Single-story vs. two-story (single is cheaper)
- Roof pitch (steep = more labor)
- Roof material (tile/metal cost more than shingle)
- Shading (may need more panels or tree removal)
Equipment choices:
- Standard panels vs. premium (LG, SunPower, REC)
- String inverter vs. microinverters
- With or without battery backup
Company factors:
- National brands (Tesla, Sunrun) often cost more
- Local installers typically 10-20% cheaper
- Avoid door-to-door salespeople (highest markups)
Texas Solar Incentives (2026)
Federal Tax Credit (ITC): 30% of total cost This is a dollar-for-dollar tax credit, not a deduction. If you owe $5,000 in federal taxes and have a $5,000 credit, you pay $0. State incentives: Texas has no state solar tax credit or rebate. Local utility rebates:
- Austin Energy: Up to $2,500
- CPS Energy (San Antonio): Up to $2,500
- Some co-ops offer rebates
Property tax exemption: Solar doesn't increase your property tax in Texas (100% exemption).
