I have built my solar radiation sensor!
Like many on this forum I have considered those transparent boxes as well as the garden lights that already integrate the PV cell.
Eventually I decided to go for a black aluminium box to avoid reflexion with basically full exposure of the sensors. Question is how it is going to behave when exposed to rain, high humidity and harsh sun. Let's see.
I used a test board to mount the components, the plugs and kept R1 and R2 as adjustable. The PV cell and the UV sensor are glued with Araldite glue, which is very strong. I have then added a silicon joint (not visible on those pictures) around the cable hole and the PV cell.
So far the UV sensor does not output any voltage, I will replace it - I should test it before gluing it.
Regards.
