Solar panel adoption is increasingly growing in the U.S., as companies and homeowners embrace the cost savings and environmental benefits.

Why it matters: Solar panels reduce greenhouse gas emissions and can improve air quality. They also lower your energy bill by an average of $1,500 a year.

By the numbers: Residential solar power grew 40% in the U.S. from 2021 to 2022, per the Solar Energy Industries Association.

Between the lines: Tax credits and health are also among the top reasons homeowners consider solar, per Pew.

Zoom in: Here's what you need to know about installing solar panels in Colorado, according to Tanner Simeon-Cox, Colorado program director for Solar United Neighbors.

1. How do you know if your roof is right for solar panels?

South-facing roofs are the most ideal; east- and west-facing are OK; and north-facing roofs typically won't work for solar, Simeon-Cox says.

Of note: If your roof needs repairs or replacing in the next five to 10 years, Simeon-Cox recommends updating it before installing solar panels. Taking them off and putting them back on are additional costs.

2. Do you have to own your home to get panels?

Yes, you typically need to own your home to install panels, Simeon-Cox says. But in Denver, there are options for renters, too.

3. What's the general price range?

Solar runs around $3.25 a watt in Denver, Simeon-Cox says. Homeowners can expect to spend around $22,000 for solar panels.

4. What happens when the sun's not shining?

Your solar panels won't run in the dark, but typically they produce more energy than you need during the day, especially in the summer.

5. How long do solar panels last?

You can expect your panels to last about 25 years, Simeon-Cox says. At that point, efficiency and output might slow — both signs it might be time to replace your panels.

6. How can I find an installer?

7. Will solar panels work in the snow?

Production will drop if there's snow on your panels. But they're designed to shed snow pretty quickly, Simeon-Cox says.

Yes, but: Solar energy production does decrease significantly in the winter for mountain communities.
