I can't see that they're actually selling solar panels. What I do see is them selling a specialized switch that is powered by solar panels and a battery that can then be used to power remote devices in locations where they would otherwise need to run power lines.

It's not traditional networking gear, sure, but I can certainly see the play they're making, so I wouldn't call this a scatter-shot approach.

They did sell solar panels but the product line was mostly killed. Product number SM-SP-260W-DC-US. You can find a legacy datasheet for the product family still.

But I think this is an example of them having an ideas they only end up abandoning. They are now selling an access control solution, but would you trust them to be standing behind this in 5 years? Enough to deploy it to a customer building? Not me. Attractive for the hobbyist perhaps.

I think some of their seemingly wackier stuff makes marginally more sense when you think of them trying to outfit their WISP customers - having solar to power stuff on your rohn tower, manage it all from one pane of glass, that kind of thing. They had a whole line of managed power products (since abandoned) for several years aimed at this crowd.
