In either case, a module should be supported and secured in the areas where the bolt holes are in the frame otherwise it may be damaged due to weather. It is important that the module is properly tightened down regardless of the system that is used to secure it, but not to the point that it distorts the frame at all. The manufacturer will have specifications for how tight is appropriate on the specifications sheet for a module, but to properly tighten a bolt to these specifications an adjustable torque wrench is necessary. In many parts of the world adjustable torque wrenches may be cost prohibitive or uncommon, therefore an installer may to rely on previous experience using a torque wrench or simply upon good judgement. Either mounting style (using the holes or clamps) can be used with a variety of different mounting systems that have different advantages and disadvantages that typically make one type the most appropriate for a given application.
