If you are in an area prone to hail, maybe a bad idea.

Here's a fun story...

quote:

The extent of the damage at a Scottsbluff solar farm that was heavily damaged in a hailstorm last week remains unknown.

“They’re still working through that process,” Grant Otten, spokesperson for the Nebraska Public Power District, which buys electricity from the solar farm, told Cowboy State Daily.

Cowboy State Daily reached out to Sol Systems, which financed and developed the project, but didn’t receive a response.

While some of the solar panels at the farm may be salvageable, as well as other equipment, it’s likely many of the panels will need to be discarded.

Even if solar panels aren’t destroyed by weather events, they gradually stop producing much electricity and reach the end of their lives in 20 to 30 years. By 2050, the International Renewable Energy Agency estimates that 78 million tons of solar panels will come to that point.

Recycling

While renewable energy proponents are pinning their hopes on recycling to deal with this coming deluge of e-waste from dead solar panels, only about 10% of them are recycled, and only a small portion of any single panel provides recoverable minerals.

B.F. Randall, who has a background in project development and finance, told Cowboy State Daily that a lot of people are under the impression that recycling a solar panel means you make a new solar panel.

“A solar panel has very little mineral content relative to the volume of the panel,” Randall said. “So, it's just not something that can be recycled in that sense.”

Newer tier 1 modules are quite hail resistant. I have a 40kW system in west Texas thats been through dozens of hail storms with not a single issue. And while that's only my personal experience, I monitor enough systems across the US and it's territories that I can say with certainty it's a blow out of proportion talking point.

Comparing resi systems to utility ones where they many times use non-tier 1 garbage arse panels isn't really a good way to understand it.
