Hi Zdenek,
Thanks for sharing your experience, hope it helps others that are now starting to build their Solar / UV sensors.
Without protection, the resin on top of solar cell don't resist for more than a winter. A thin glass placed directly on top of the solar cell, will make it last for several years and have no impact on the readings (don't leave space between the solar cell and the glass). After that, cleaning the glass one or two times a year is all what is needed.
