This experiment lasted nearly 5 months and turned out to be a great success. Installed on a roof in Chisinau, thanks to my good friend, we weren't expecting much, as the location was far from our perception of ideal (which is one of the reasons why we haven't installed it at the time of the winter solstice, as we initially planned). After we got the scan and made some basic processing on it (inverting and adjusting the curves), we were pleasantly surprised by the result! We are now searching for a new spot for my next Solarcan...
