Today, 03 August 2022, we finally adjusted the panels of the test array to 35° inclination. The morning was clear and fairly bright; a hot day with air temperatures in the region of 30°C.
And we easily reached our target of over 700 watts per square metre output. In fact, we got peaks of up to 750W/㎡ with water at 30°C inlet temperature!

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…
