Residential micro fit under 10 kwThey are also planning and a residential inverter 5kw @ about $2,500 each for release by this summer. They would have to tweek the inverter they have to 240 volt. Would be a great match for south facing residential roofs with aprox. 30 degree roof incline. 10k systems can generate $14,000. annually. A 5k system, half that, but very affordable; especially if they can come up with a self install system.
