The build quality is below average when compared to other brand like luminous. There are some visible scratches in the glass covering the module. The frame material is not good and it cannot withstand high wind for long years. The output current never touches the given 9.3amps. I tried all angles and every half an hour in bright sunlight. The maximum current given by the panel is 8.23. In my opinion it may not lasts longer than 5-6 years. After 15 days of use I get only 224 watts maximum during 12.45PM to 1.30PM when both panels are connected in parallel (Not 360 watts maximum). The maximum peak working current provided by both panels in parallel are 16.32 amps only i.e., 8.16 ampere for each panel. The efficiency is slightly lower than poly crystalline panels. So in my view mono crystalline panels are not better.
