nice one! i wish regulations were easier in germany, where you could never ever build something like that by yourself as it is required to be approved by a structural engineer and the district office ...

excellent travail !
bravo

@owl ... you can dow everything by your own .... but i always have to laugh seeing those americans messing round with powerlines. seems like they never get used to put everything below ground surface ... AC lines at ca. 1,80 m ?? never ever ... XD
