These were left behind by Solyndra
Want some left over PV tubes?
These were the tubes used in the Solyndra solar panel/module
We can use spring-loaded fluorescent tube connectors or Light Fittings
The PV tube is inserted into, and held between, two connectors.
Test PV tube in sunlight (Isc > 52 mA, Voc 100 V).
You can make your own mini-module and compare it to a flat plate PV
One can study them at tilt and horizontal
There is a silver lining in the Solyndra story - Education
We are measuring Solyndra PV Panels at Santa Clara University
Measuring them in the winter
Greg Smestad and experimental set up on flat roof.
We can compare the Current-Voltage Characteristics
It's the current density that matters.
Solyndra Panel without white backplane reflector
Closed-form Theory (Prediction). Flat is as good at cylindrical
Cross section showing critical angle (60 deg.)
At shallow angles, it looks like a flat PV
As you move past the critical angle light reaches the back
The modules are horizonal and connect to neighbors via mounts/feet
Solyndra PV panel. Light passes through gaps between tubes.
Solyndra PV panel is made of an inner glass tube coated with CIGS inserted into the outer glass tube.
Solyndra label showing the specifications & certifications
One Solyndra tube is about a meter long and contains separate cells
The cells are in electrical series, so each tube is a mini PV module
Each tube is in parallel with other tubes. Each 7 mm stripe is a single (series connected) CIGS PV cell.
The array of tubes (mini-modules) are spaced from one another and the ground/roof
The light goes through the space between the tubes and creates shadows and reflected light
Two modules connect and use only 6 (not 8) feet/mounts

CPC "W" Reflector, close up
GlasStress Ltd. AP-07. Purchased from Solyndra
AP-07. This measure the surface stress of the glass.
Who is this guy? More here in the comments.
What to do with all those tubes?
People seem to like the full length as a floor vase
