@Biswojit yes you can apply in this ipo in retail application, here their business type and sector both are great and they are showing good and consistent growth in their revenue and profits which will still keep growing at good pace in my view, they have great order book and their margins also increasing due to solar sector O&M services....
Some concerns are big size issue without qib, bad market maker image due to some recent ipos, (Lead Manager coming after long time and handled few issues and looks average) and increase in borrowings which is usually there in such kind of business due to working capital needs...
Overall i don't feel it will list negative so no need to fear here in my view and it should do in mid to long term holding also...
still if possible , we can sell in grey and then apply in retail else apply open....
