I have been studying HMS Photovoltaik and attempting to unravil whether or not the investment is really worthwhile as compared to the normal PV systems. The greatest benefit that I continue to experience is the micro-inverter installation that will give the best out of energy generation when few of the panels are shadowed or soiled. According to numerous users, they are getting much more noticeable yields than with the traditional string inverters. I wonder what happens to this in the long run and whether the resultant increased efficiency would justify the small increase in cost. Get any real life numbers, particularly in mixed sun light conditions?
