Electricity and shade

This USBank, formerly Downey Savings, is just 5 minutes up the road from my home, so I pass by it all the time. I noticed these girders being put up the other day but I couldn't figure out what they were for. Since the top ones are slanted they certainly were not adding more floor space for the bank.

I stopped by today and found out they have a dual purpose. First, they are for the placement of solar panels that will supply electricity for the bank and second, they are strategically placed over the bank's parking lot and will supply shade for the bank's customers.

I especially appreciate how the bank has kept the beautiful pine trees that dot their property.
