Cost Per Watt
- Laredo average: $2.50-3.10 per watt
- Budget installs: $2.30-2.50 per watt
- Premium installs: $3.10-3.60 per watt
Note: Laredo pricing may run slightly higher than major metros due to fewer local installers, though competition is increasing.
Payback Period
At $0.11/kWh average electricity rates, Laredo homeowners typically see 13-16 year payback periods. However, the exceptional sunshine means more production per panel, which helps offset the lower rates.
