I'm getting two new 200w PV panels this week. These were a bargain that I could not pass up.

That got me thinking (again) about doing a legal Grid Tie Inverter connection.
All I would need is a couple of Enphase GTIs, Roof mount hardware etc. and a little paper work.?.

Reason:
I'm starting to think that my Sanyo uses around 440w on average, during the heating and cooling seasons.
(0.44 kWh per hour x 24 = 10.56 kWh per day).

So, those two panels could actually pay for much of our heat/AC during the prime daylight hours.
On cloudy days and at night, we would have to pay..

Unless, we were banking kWh during sunny days when the Sanyo was off..

My point is, the Sanyo uses so little power, even a small GTI array can be very helpful.
If you live in an area where they charge more than 20 cents US per kWh,
it's an idea you might want to research..

Cheers,
Rich
