Texas solar policy planning
Solar savings depend on two values: electricity you avoid buying from the grid and exported solar energy your utility credits back. This page explains how SolarCalcNow models export value as a planning assumption, not a final utility-specific tariff.

Value of Solar credits total production, not just exports. This calculator's self-use/export split does not reproduce that bill. Other Texas retail, municipal and cooperative plans need separate checks.

10%, 35% and 100% of retail are author-selected sensitivity scenarios, not this utility's tariff. Same inputs: 900 kWh/month, 100% annual energy target, 55% direct solar use, low shade, 400 W panels. Change only export value to see its effect on energy savings and gross-cost payback.
| Export / retail | Annual energy savings | Simple gross-cost payback |
|---|---|---|
| 10% | $1,024 | 11.5 years–17.2 years |
| 35% | $1,218 | 9.7 years–14.4 years |
| 100% | $1,722 | 6.8 years–10.2 years |
Annual totals cannot reproduce hourly export prices, monthly credit expiry, demand charges or utility-specific minimum bills. Match the utility and interconnection date before selecting a scenario. For an actual proposal, request a bill simulation under that tariff.
After checking export value, compare the same assumptions against installer proposals and incentive claims.
