Curious, how long do they think the solar panels will last before replacement? Are they somewhat hail proof?
NAIT has done testing a 5 year study in brutal weather and snow. Edmonton is good b/c we get a lot of sun. I personally know 7 people who got the same panels as me.
On average, most panels degrade 0.5% a year. Supposed to last 25 years.
looked at 12 solar modules installed atop the Shaw Theatre on NAIT’s main campus. It measured the impact of snow on the system as well as how the tilt of each module affected energy production.
Researchers found the angle of the solar panels has a far greater impact on energy production than snowfall. The ideal angle for maximum energy production with snow accumulation was 45 degrees.
Data was collected from the solar modules every five minutes every day for five years – enough to fill 6,000 spreadsheets. Two Alternative Energy students analyzed the data as part of their final course project.
They are designed to withstand hail with testing, but nothing is guaranteed with that IMO. I would be nervous lol. Putting them at 45 degrees is supposed to help as well I believe. Hail that is about 1.8"-2" can potentially damage them. They are pretty strong under that.
Just have to hope almost baseball sized hail doesn't hit
