Texas-specific
City selection changes the electricity rate, solar resource, and installed-cost assumptions used in your estimate.
Estimates are for educational and planning purposes only. Actual solar production, project cost, savings, incentives, and payback can vary based on roof conditions, equipment, utility rules, financing, installation requirements, electricity rates, and other factors. This calculator does not automatically apply a federal tax credit to 2026 estimates.
What solar costs in Corpus Christi right now
Installers in the Coastal Bend market are quoting close to $2.80 per watt for a straightforward cash purchase. For a home using about 1,150 kWh a month, that means a 8.5 kW array around $23,672 before incentives. The 30% federal residential clean energy credit brings $0 of that back, landing your net cost near $23,672.
Financed proposals in this market frequently arrive 20% to 30% higher for identical hardware, because the lender's dealer fee is folded into the contract price. Ask for the cash price alongside the financed price before you compare anything.
Electricity rates and why they matter here
Corpus Christi households pay roughly 14.6¢ per kWh, which puts a typical monthly bill near $168. Every cent of that rate is money a solar array can offset, which is why two homes with identical roofs in different Texas cities can have payback periods two or three years apart.
AEP Texas and what happens to extra power
No statewide net metering. AEP Texas handles delivery; buyback comes from your REP.
This is the detail most Corpus Christi homeowners skip, and it is the one that most often makes a real system underperform its proposal. Read our guide to Texas solar buyback and net metering before you approve a system size, because weak export credit is a strong argument for a smaller array.
Sun exposure in Corpus Christi
Corpus Christi averages about 5.2 peak sun hours per day. After a realistic 14% loss for inverter efficiency, wiring, soiling, and summer heat, each installed kilowatt produces roughly 1,632 kWh a year here.
Orientation matters as much as geography. A south-facing plane with no shading is the baseline. East-west splits lose roughly 10% to 18%, and meaningful tree cover can take 30% off production. A shade study using drone or satellite modeling should be part of any serious proposal.
Incentives available to Corpus Christi homeowners
- 30% federal residential clean energy credit on the full installed cost, including labor and qualifying storage
- Texas property tax exemption on the added appraised value, filed with your county appraisal district
- Local utility rebates where AEP Texas offers them, subject to annual budget
Choosing an installer in Corpus Christi
Get three quotes, and make at least two of them local companies that have completed AEP Texas interconnections before. Ask each for cost per watt, the production estimate in kWh with its modeling assumptions, the workmanship warranty length, and who files the interconnection paperwork.
Then compare those quotes against the estimate above. A proposal within about 15% of this model is in the normal range. A proposal 40% higher needs an explanation you can point to on the page.
