Okay, this is going to be a strange question. I'm looking for the lowest
cost way to install a single solar panel and inverter that is grid tied. i
need it to be grid-tied and it needs to be monitored in some way. I'm
thinking a microinverter is the way to go, but I don't want to buy a $600
Enphase Gateway to make it happen.

Since someone is probably going to ask, I will go ahead and explain. A
local utility company has a top marginal residential energy use rate of
about 15 cents per kWh. The first and second 500 kWh monthly are billed at
a slightly lower rate. However, when you enter into a netmetering
agreement, the switch you to a "blended" rate, which is currently 9 cents
per kWh, regardless of what you net energy use ends up being.

You might see where I'm going here. Installing a single netmetered panel
reduces a customer's marginal rate by 6 cents a kWh. This could be a
substantial savings, particularly for heavy energy users.

I have people interested, for obvious reasons.
