Dear Dr. Andre, with regarding the question of Mr. Christophe: is there any other affect of the array? (in case it's array that connected to the same MPPT of the inverter)? is the voltage of the whole array decrease also, for instance in case of 1 or 2 bypass diodes of the string that installed on the bottom are on? or the inverter will keep the voltage level of the "strongest" strings anyway? is there any difference between central inverter or a string inverter (with one MPPT)? i guess there is no difference but i'm not sure.... :) are other strings of the array, which are not shaded ,could produce less energy in that case, or only the shaded string is affected? Many thanks Oron
