Some 6MW of ground-mounted capacity has been commissioned outside the Lake Pleasant water treatment plant, which produces 15 billion gallons of tap water each year, and will now see 70% of its electricity needs met by the sun. Another 1.5MW was built atop a nearby reservoir using SunPower’s T10 “solar roof tiles”.

SunPower, which will stay on to maintain the sites, used nearly 23,000 modules in total, as well as its T0 trackers to maximise output at its ground-mounted array.
