Question 1

What efficiency range is currently acceptable for solar panels?

Accepted Answer

Solar panels with an efficiency range of 18% to 22% are considered excellent for most residential and commercial installations in 2025.

Question 2

Does dust accumulation affect a solar panel's output?

Accepted Answer

Yes. Dust and dirt accumulation on solar panels can reduce their performance, which is why regular cleaning is important to maintain maximum energy output.

Question 3

Are high-efficiency solar panels a good choice for small rooftops?

Accepted Answer

Yes. High-efficiency solar panels are ideal for small rooftops because they generate more electricity from limited space.

Question 4

How long will a solar panel remain efficient?

Accepted Answer

Most high-quality solar panels have a lifespan of 25 years or more, with only a gradual and minimal decrease in efficiency over time.

Question 5

Does the quality of installation impact solar panel efficiency?

Accepted Answer

Yes. Proper installation, including correct panel orientation, secure mounting, and adequate ventilation, plays a critical role in achieving optimal solar panel performance.
