There's 26, 315 W panels. Utility price for avoided cost is only $0.10 kWh and they haven't sold any back.
6710 kWh generated seems a paltry amount for that size array and cost!

That's what I'm saying, even conservately they should've produced alot more.

Very inefficient panels? They're quite dissapointed about it. I was much more hopeful about kWh generated than actual results.I'm gonna try to dig into what they have going a little more.

8kW is a HUGE array, do they have storage?

No storage. No batteries. They haven't even produced enough to sell back.

Their system isn't working properly. The numbers you gave me don't make sense unless some of the panels are partially shaded/damaged in some way.

Shit site probably.

After looking at this map, sounds like he's close. Seems Alaska has about half the solar gain of Arizona.

The problem is where it's coming from; without sun tracking, you'll get much less than in AZ.
Then there's the whole winter thing. Not a lot of sun up there from October to February.

Yeah, trackers would be key, still a shit load of atmosphere between the sun and panels.

Id imagine a tracking system for an 8kW array would be prohibitively expensive so I didn't even mention it.
The steppers/servos with rigging alone would cost an arm and a leg.
I built one using a pseudo-gimble design (for 360 x 360 coverage) for a small panel as a novelty, was cool but not practical at all.

Yep, but they sure are cool. I haven't checked, but I imagine the gas ones aren't too expensive and really basic.

Gas? Doesn't look too robust to me...
Justin-case

Yeah, they look like a car strut, and are filled with a gas that expands as it warms in the sun. Pretty cool, but I think the rotation and timing is limited compared too a tracker.

There's no need for an active tracker to use much power, and the daily gains are substantial. The further north, the more they're necessary to make the returns worthwhile.

There's nothing quite like being around a solar array when they wake up and start moving towards the sun, it's alive!
