The day has long gone when “building unveils solar array” is much in the way of news – but I’ll make an exception for Dover High School, which installed a rooftop array so big that it increases the state’s (admittedly small) solar capacity by 1.5%.
You can see the picture of the 912-kilowatt array (2,581 panels) above, courtesy of ReVision Energy, which installed it. (They’re putting panels on my house, too – only 18 of them, however; no perceptible impact on state solar production is expected.)
There are larger arrays in the state, but so far as I know they’re all ground-mounted.
Why every large, flat, modern* building roof doesn’t look like that is beyond me.
*Many old mills and factories that seem perfect for rooftop solar have supports too widely space to add the weight of panels; they’re already pushing winter snow-load limits.
How does this preform when covered with 18″ of snow? And, aren’t most flat roofs shoveled off after heavy snow? How is that accomplished with the panels installed?? I really interested in the Solar Roofing Tiles from Elon Musk. I haven’t heard anything about that in a bit. Solar Tiles and a Power Wall would be great!
