| CenterPoint Energy | wires company (you choose your plan) | CenterPoint’s solar program page lists an incentive of $135 per kW (cap 15 kW) for existing homes in its Houston territory; that page is not recently updated, so ask before you count on it. |

What to plan for in Katy
- Drought (relatively high): Drought raises fire and heat risk and strains wells. If you rely on a well pump, include it in your backup plan.
- Tornadoes (relatively high): Tornado-season storms cut power quickly. A battery that switches on by itself, or a portable generator ready to go, covers the first night; sirens and weather radios need power too.
- Hurricanes (relatively moderate): Hurricanes can mean a week without power. A standby generator on natural gas or propane, or a battery with solar, beats a stack of gas cans; check flood height before you site equipment.

Out of direct afternoon sun, in a spot the maker approves. Heat in Katy (about 3,160 cooling degree-days a year) is the main limit.
