			Hi Kevin,

	~~Hi Kevin,~~		Thanks for getting out the proposal so quickly. I have a couple of questions

			* I like the idea of microinverters so when the chimney shadows a 40% of a panel the whole system doesn't tank. Does your design require/include an IQCombiner or QAggregator?
			* What type of monitoring device do you use? Does it give per panel monitoring? Is it the IQ Envoy?
			*The common panel that this system would connect to is a 60AMP panel a couple of circuits for basement electrical and hall lights. What breaker size would be needed coming from the inverter into my panel for your proposal panel?
			*What is the weight of the panel and racking?
			*What type of racking do you use? Could I see specs or example installs?

	For wind turbines the industry average installed cost is about $2 million per megawatt, about $2.00/watt. Over the course of a year, however, a turbine produces only about one-third (33%) of its theoretical maximum capacity So it costs about $2/1/3watt or about $6/produced_watt/yr. Run for a year each watt of capacity produces 24365/1000 or 8.76kwH of electricity which priced at $.166/kwh creates about $1.45 worth of electricity. Simple payback in 6/1.45 or 4.13 years. Each kW of wind capacity produces 1/324365 or 2920kWh/yr (at Boston rates $.166/kWh2920kWh=$485, a MW turbine would produce $485,000 Actaully producers get about .05/kWh so it is more like $146,000/yr with simple payback taking 13.7years)		For wind turbines the industry average installed cost is about $2 million per megawatt, about $2.00/watt.
