I had one on my deck. It was about the size of a pack of cards and was from Europe, of course it might have only been 100 watts or less. <div><br></div><div>The biggest issue with the bigger players here is that they are all 240vac, which makes simple install difficult. </div><div>And for some reason, the enphase can just fail if you don’t have them connected via their gateway. </div><div>I have 4 that are connected without the gateway and 1 just failed.

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. </div><div dir="auto"><br></div><div dir="auto">You might see where I'm going here.
