95 miles NW of Quitaque, TX | There are solar panels that get close to 24% efficiency but a good average is 19-22%. The older solar panels are less than those numbers.
I saw this statement.
The panels themselves last 30+ years. The inverters range from 10-25+ years, but they can be replaced for a much lower cost than the original installation. That said, ROI in many locations is 7-10 years, not 20+.
You need to ask how many hours per day to solar panels produce peak power. That number is 3-5 hours. When the sun comes up the solar panels produce a little bit of power but not much until the sun gets up plus or minus noon. In the northern US that number can be zero.
My guess is the solar panels will be replaced before the 30 years. This is what I have seen over the years. Average life span is 25-30 years. |
