Our POCO (PSE&G) is installing approx. 220,000 of these single panel PV units. They are grid tied only.

Greg:
The specs are supposed to be in my office by Monday or Tuesday at the latest. It's a micro inverter, and tied into the triplex 120/240 or 120/208 secondary on the poles.

FYI, I've had a few townsfolk call up to inquire, and a few asking if 'they have permits', and one who screamed 'what ..... approved that?'

It is an interesting experiment. From what you said about your electric rates it will save about 20 cents a day

That .20 cents a day, times 220k panels equates to about $44k. But, it's not saving me; it's all POCO (PSE&G) owned.

If you are a customer, it is still your money.
My guess is those panels are about $1700 each retail based on my shopping but I am sure PSE&G got a price break buying close to a quarter million of them. Too bad they weren't made in the USA. We could use the jobs.

I read the white paper about the "Up" system but I am curious how they know if each unit is working. Driving around checking them manually will gobble up that profit pretty fast.
They do talk about remote communication but it was not clear what that does. Is it remote metering?

Greg:
I noticed on some units a device mounted underside of the panel with an antenna, which I think is some type of wireless comm. This may be what they show on the mfg site.

These devices are 'utility' owned & installed, so I have no Twp info. However within the next 2 weeks, I expect to have some 'un-official' data from my POCO contacts.

The other panels at the 'Big' site are from another mfg.

I suppose they call home every once in a while with performance data. That is really the only way to know they are working without going up the pole.

Thinking about it...IF each panel has a comm device.....that has to jack the unit cost up at or near $1k with the mounting hardware, wouldn't you think??

220k panels @ $1000 is $220,000,000, that's a tough nut!
