It’s been awhile since I last undertook a significant construction project (years actually). Building this superstructure for a 2.9Kw solar photovoltaic array out of simple materials for my off-grid house was a personal challenge. The design is a replica of one my neighbor up the road devised. Except for a little help from my son in the beginning (digging the shelf into the hillside and placing 4 of the 6 steel pipe columns), I did the entire project myself. With this array charging a 595 amp hour battery in sunny California weather, I expect to rarely, if ever, need to use the back up generator!
