2.1 Rooftop PV System. Rooftop PV system is having PV panels as source, DC-to-DC stage to maintain PV voltage at Vmpp and DC-to-AC stage to fed extracted power into the grid as shown in Fig. 1.DC-to-DC stage can be realized by means of any DC-to-DC converter (Isolated/Non-Isolated).
Voltage unbalance in the system creates varieties of problems, such as poor power quality, higher power loss, and lesser system efficiency.
