Do solar panels actually save you money?

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 5.4% per year on average. Over 20 years, that compounds significantly. Solar locks in today's rates. Your $120/month savings today could be $180/month in 10 years if rates keep climbing.

How much do solar panels save over 25 years?

$39,407 over 20 years assumes 5.4% annual rate increases. Could be more if rates spike like they did in 2021-2023.
