diy solar grid tie

[b.jJames]

I know , I know , they both use electricity ????

[kellyvb]

Guess I missed something. What does a Solar grid tie system have to do with an electric vehicle???

[J.P.M.]

My array was approved with pge the 19th the same day I submitted the interconnect form. my 285 watt panels with m250 microinverters are producing 220 watts at peak, is that sound normal? The panels are 14 degree tilt and facing 200 degrees.

That output sounds similar to mine for close to the same day.

FWIW, my output on 10/22 at the time of minimum solar angle of incidence on the array (1253 HRS., P.D.T.) was 3,985 Watts. System STC size is 5,232 Watts. P.O.A. irradiance was 914 Watts/m^2, total P.O.A. irradiance on the array was 23,850 Watts,. Amb. air temp. @ the array was 33.4 C.. Amb. temp. at ground level was 28.9 C. Average panel temp. was about 53.6 C. Wind velocity @ the array was 3.2 m/sec. Array tilt: 18.75 deg. Array azimuth: 195.75 deg.

Yours: 220/285 = 0.772

Mine : 3,985/5,232 = 0.762

If you're PGE you're probably not too far from me - I'm in the south bay.
I have 285W panels with solaredge system.
I am getting a peak of about 195-205W for my panels at ~165 degrees and ~18 degree tilt.

The problem with cleaning the front side glass, is the Anti-Reflection coating can easily be damaged. Tape residue can be removed from plain glass using lighter fluid for wick lighters (I think it's naphtha). I'm not sure if it's safe for the panel edge seals or the AR coating, but apparently it's safe to use on expensive guitars:

Ok thanks. The panels have a little bit of adhesive from the scotch tape over some of the PV cell on the side, how do I clan the panel?

A little water and an old credit card should be sufficient to scrape scotch tape residue off I think. (credit card plastic should be soft enough not to scratch the glass)

Make sure you tell Enphase that you are the installer in the account setup, so that you don't have to pay extra for the Enlighten Manager.
Oh, and make sure to keep track of which inverter goes under which panel, maybe take a picture of each label. You'll need that info to "build" the array on the website. I don't remember if there is anything you can do before turning on the inverters, but I had my system up and running (without the Envoy) before I even took the envoy out of the box. Setting up the Envoy and monitoring was the last thing I did.

Another tip: If the panels come in a box on a pallet, with the panels resting on their sides, be careful how you remove them. After I'd removed about 2/3 of them, I realized that the panels I had removed were the only things keeping the box and the remaining panels from tipping over. That was embarrassing. I had to get my wife to keep the box from tipping as I removed the remaining panels.

Will I be able to configure the Envoy communicator w/o turning on power to the panlas?

For the 240" rail it just fits. But for my last row of 3 panels I need to be creative, Renvu gave me wrong measurements for the end clamp. My delivery is scheduled for today......talk about a learning experience.

[foo1bar]

Just my luck the Unirac are exact measurements.

So my SolarWorld panels are 39.41" wide portrait, should I put the first Enphase M250 micro inverter at 25" and then 50" thereafter?

How wide is the space between modules for the midclamps?
How much space is needed for the end clamps?
Probably is enough to make it so won't fit in 240 inches, but I haven't looked up the numbers.

Have you already ordered the racking?
IIRC I used 11' ironridge rails for my 6-module/row array. (with splice near the middle and trimmed to be a little shorter than 22'.)
Maybe you can change from 20' to shorter ones and splice.
If it were me, I'd want the splice to have two feet on each side of the splice.
I definitely wouldn't want to try to splice on just 1 foot of rail - I would be worried about it - especially since the end modules of an array are more likely to have more wind force on them.

[billy1]

Yep 1 micro inverter per module. Every 40 inches sound good to me thanks.

[foo1bar]

Why not every 40 inch per the enphase portrait cable spacing?
Aren't you doing 1 per module?
