The Real Cost of Waiting for Solar Panels in Texas
Rates from Oncor, CenterPoint, AEP Texas climbed as much as 8% over the last 12 months, part of a longer 3–5% annual climb this past decade. Texas homeowners paying $0.16/kWh today are locking in tomorrow's higher bill unless they generate their own power — $1,440-$2,880 a year is what's at stake.
To give you a reliable picture, these estimates are built on strictly conservative assumptions: no expired incentives, includes ~4%/yr electricity rate increases (EIA historical avg), Limited net metering · ~80% self-consumption assumed. While other sites inflate their numbers to close a sale, we show reality — so the savings you see here are savings you can actually count on.
