Solar bus canopy reduces temperature by up to 20 C
The University of Sevilla has designed a PV-powered "smart" canopy that activates a thermal conditioning system to reduce extreme heat by up to 20 C.
After getting solar, my total energy consumption in Texas during this record-smashing heat is down by a few percent compared to this time in previous years. That is to say, it's not just that I'm importing less because now I get it from solar collection, but I'm just consuming less over all combined sources.
It really makes me fixate on how many naked roofs are still just soaking up this shitassed heat and paying extra money to push that heat back out, all while producing even more heat to do so.
My tiny 1.6 kWp DIY PV has been averaging 6 kWh/day the last 5 months. If this holds up over the year I'll be making 2/3rds of my net electric power myself. ROI is about two years. I'll probably bump it up by another 400-800 W this year and add a few kWh storage next year.
