These things don’t generate very much power, 5kW @ 208V 3-phase is only 13.88A which means it can’t even run a single 5HP motor. It’s equivalent to ~25 200w solar panels. You’d need 30 of these just to power a single 208v three phase 400A panel, and the size of building these would be installed on will typically have a 2000A or larger electrical service. Assuming it runs at full capacity for an entire year and electricity costs $0.10/kWh, it would save $4,380 a year, but obviously it won’t generating at 100% all the time. I fail to see how these would ever pay themselves back, I’d guess one of these units is between $30-50k installed, possibly more. The roof might need structural reinforcements which could push the cost higher. There will be electrical distribution equipment to transfer loads between the wind powered generators and utility power.
