That's a very interesting approach to the problem. It's almost the exact method that I've been considering.
Bypassing the legal requirements is a plus. But, it's for
very small PV systems with low output.
The two small PV packages that I've been eyeballing can make 700W & 1400W.
Enphase Grid-Tie Packages
I'm not sure what my 'standby' load is, but my guess is under 700W.
So, I would want a fully legal grid-tied system, so as not to be wasting
any extra power made during the day when my use is low and the sun is high.
I have received the info pack with the required forms from the power company, and it doesn't look really complicated.
If my town inspector(s) cooperate, I should be able to DIY and get the net-metering installed without a hitch.
If the inspectors don't cooperate, a low powered Stand-by load mini-system
using the Enphase inverters with some panels in the backyard is my plan-B.
Since there is no way that I'll pay $15,000 for someone to install a $4600 system.
When the tax breaks etc get wiped out by
labor cost, the break-even moves out past my life span.
Cheers,
Rich
