I bought 2 mono crystalline panels of 180W each. It is specified that these panels work well in cloudy weather. Out of 360W on an average I noticed 50W these 2 panels producing that too when used MPPT charge controllers with DC wires. In Bangalore the rainy season we see sunlight rarely. Though it is producing energy entire day and not even equivalent to 1 unit (Kwh) of energy. So not so productive and efficient as expected. The build quality of frame as well not that much great and it is shaky for normal winds itself. So I need to see its performance on sunny day. Loom Solar packing is also not good, external cartons got damaged and even no thermocol filled inside to protect from movement and shock any. Shipment over road transport needs good packing.
