Question 1

What is the most efficient type of solar panel?

Accepted Answer

Monocrystalline panels are currently the most efficient option for residential use. Models equipped with PERC technology can reach efficiency ratings of over 22%, allowing you to generate more power in less space.

Question 2

Can I mix different types of solar panels on my roof?

Accepted Answer

Generally, you should not mix different types of panels. Connecting Mono and Poly panels in the same system can drag down the performance of the entire array to the level of the lowest-performing panel. Uniformity is key for optimal energy production.

Question 3

Do solar panels work on cloudy days?

Accepted Answer

Yes, solar panels still generate power from diffuse light on cloudy days, although their output will be lower than on a sunny day. Monocrystalline panels are typically the most effective at capturing energy in low-light conditions.

Question 4

Are solar shingles better than regular panels?

Accepted Answer

Solar shingles are better for aesthetics because they lie flush with your roofline, but they generally cost significantly more and offer lower efficiency than standard rack-mounted panels. They are best suited for homeowners who are already planning a full roof replacement.

Question 5

How do I know which type of panel I am buying?

Accepted Answer

You can verify the panel type by checking the specification sheet provided in your installer's quote. Look for the "Cell Type" section to see if it lists Monocrystalline (Mono) or Polycrystalline (Poly). You can also look up the model number online for verification. You can learn more about typical panel specifications on the Department of Energy's solar management pages.
