[amsat-bb] Re: Cubesat Group purchase of EMCOR cells

[Ignacio de León]

Hi everyone,
I want cleared something.
We are searching solar cells or non qualified solar cells for a cubesat to
make electrical test.
It is not important if they are form Emcore, Spectrolab or whatever.
We need between 6 and 12 cells.

Nick, how much cells do you need?

Thanks you very much
Ignacio

PD: Apologies for change the topic, sorry.
