After running a test rig with two collectors for several months (on a scaffold tower next to the office!), we’re building a ten-collector system in a more permanent location.
This one will have a more appropriate inclination for winter of about 60 degrees.
We’re very pleased with the performance so far during the summer.
There are logging data online for August and September this year for this small test system.
Once we’ve installed the bigger system, we’ll start the online data logging again.
The initial board tests yielded promising results, with only a minor issue identified relating to tracing to an ESD protection diode array. Despite this hiccup, I’m quite satisfied with the progress so far… yet, as Read more…
The system we developed is modular, with modules connected on a 2-wire data bus, with an additional 2 wires for power. Up until now, we have generally used premade pcbs connected to our own boards Read more…
The testing that we did earlier paid off. We had a nicely working prototype with a couple of collectors. That wasn’t enough, so we built a 10-collector array on some welded scaffolding. Our problem is Read more…
