Photovoltaic Concentrator

While I was at the Solar 2 plant auction, I noticed this item which appears to be a evaluation fixture for PV concentration.

The unit has 32 plastic "troughs", all mounted on a Az-El pedestal about 5 feet off the ground.

each assembly has about 24 Fresnel lenses note the heat sinks mounted behind the focal point.

nothing great to look at, but I was trying to be thorough
