Most Houston homeowners save $156/month on electricity after going solar. With CenterPoint rates up 5.0% this year alone, those savings grow every year. Over a 25-year system lifespan, we're talking about CenterPoint rate increases that could double or triple your electric bill - but not if you own solar.

How much will I really save with solar panels?

Your bill drops because you're generating your own power. Most of the day, your panels cover your usage. At night, you pull from the grid, but your net bill is way lower.

Why do solar savings increase over time?

Electric rates in Texas go up about 5.0% per year on average. Over 20 years, that compounds significantly. Solar locks in today's rates. Your $156/month savings today could be $234/month in 10 years if rates keep climbing.

How much do solar panels save over 25 years?

$42,347 over 20 years assumes 5.0% annual rate increases. Could be more if rates spike like they did in 2021-2023.

Frequently Asked Questions

Q: Will my electric bill be zero with solar?

Why Rate Increases Matter for Houston Homeowners

Electric rates in Texas have been climbing steadily. CenterPoint territory has seen rates increase from around 10 cents per kWh five years ago to over 16 cents today - that's a 25% jump. And there's no sign of it stopping. The thing is that means for you:

Solar freezes your production costs at zero. Your panels produce the same power whether rates go up 3% or 10%. That's real rate increase protection.
