Now would be the time to invent the photovoltaic roof system with Renewable Energy Act insulation and directly mountable on the roof battens. Because the sum of roof tiles, insulation, and photovoltaics individually is already enormous. Of course, suitable for renovation and new construction.
One of our solar roller shutters is also malfunctioning, although they were only installed in 2016. I researched and was shocked to read that with such old roller shutters, not only the battery but also the solar module, motor, and battery should be replaced at once. The new solar module from 2022 is said to have better performance and be more durable, and the new motor quieter. I really wonder why Velux has taken the crank roller shutters out of their range.There is currently a problem with a solar roller shutter here. Velux wants 98 EUR for the call-out, 95 EUR/hour for the technician, 29 EUR for disposal and material according to consumption. The solar set (I assume that is what we need) costs 400 EUR for this type of window. So. We googled, opened the window (this can be done safely, you don’t have to go outside, don’t have to lean out, etc. in our case), after 5 minutes the old battery was out, we can buy the new one for about 100 EUR, and then it will be reinstalled.
For my husband and me it would be helpful if this also extended to landscapers and pavers. From them we received almost no offers or only rejection offers ... at the moment there seems to be no interest in designing round and semicircular shapes, especially in sandstone color. Without exception, everyone wanted to confine us to square, practical, gray.The old orders from some companies seem to have been worked through by now and the demand is not so stable.
