Thanks Kinnar for your comment. In his presentation, Fritsch specified that roller shutters have a seven year full warranty, which covers parts, mancraft and travel cost of the mancraft.

Solar power may be good, but I question whether building it into specific devices is a good idea. As you point out, the storage cannot be shared. Also, as can be seen from the picture the solar cell is vertical... hardly ideal even if assumed to be facing in the right direction, which many would not. It would seem far better from an engineering standpoint to have a larger panel on the roof at the proper slant and pointing in the right direction.

It is good solution for saving power, but as far as the life of the product is greatly dependent on the batteries. It would be cost effective is multiple shutters can be operated on single battery. That will reduce the maintenance man hours.

If the shutter is well lubricated and well balanced, it should be possible to open and close with very little energy - perhaps tapping off a central solar cell power system that runs other systems as well.

Yeah...very well thought ideas! These applications would be much better than the rolling shutter idea for compensating the high cost of the PV cells and NiMH batteries.

This kind of application has more value not for rolling shutters ( which is may be once in a day job mostly handled manually) but for automated sliding gates for a factory for allowing entry exit of vehicles. Such operations are frequent and if the manpower can be saved by automatic operation then it is worthwhile the cost spent on expensive solar panels.

Is this for locations off grid? I can't imagine anyone adding the expense of PV and a storage battery if they already have power. It's not at all cost effective to have battery storage in each individual device within a home/business.

This seems to be a good product into the smart home category. The question is how much it costs. For home use, roller shutters won't be rolling up and down often. For commercial such as hotel, the situation may change. Cost effectiveness is really important to commercial. In another words, if the energy saving doesn't cover the cost of the product, the incentive of getting one of these will be low.

In India, mostly the roller shutters are driven manually by hand :)

To say that Andy Weir's The Martian is an exploration of math, Mars, and feces is a slight simplification. I doubt that the author would have any complaints, though.
