Hello .... Company in Portugal is constructing panel towers ... they do look very sturdy but I think as a home owner I would not go higher than 4 panels ... the taller ones look like they could be a problem in high winds

Panel size is hard to judge from the pictures ... I think they are as wide as a car .... I do not know the weight of a panel but I would hope the structure is going to be very sturdy ...
On top of that construction cost you would still need your back up batteries unless you can share your output with the local electric company and perhaps your generation will off set the total cast at the end of the month???
