It is ok up to certain extent,frequent maintenance is needed you can make it with un broken materials.maximum 2m* 1m can be provided, small size is safe

Skylight are very good element to provide on, it will enhance ventilation as well as light. This will reduce the AC use if made with operable to open and close. Size depending on your need and this size really make the cost, so provide according to ur need. Only thing you need to consider is the glass to be used should tempered-over-laminated. Also fixing to be done with leak testing. My personal recommendation is to Go for it, natural lights are best energy sources.
