I'm so jealous! I take it you had clear skies all day yesterday? I can't wait to see what I get for our first day of all-day sun. If there ever is one again, now I have a system! :lol:

I've only estimated 26kWh for a full on summer's day. So if I can get even close to that on a winter's day, and blow it away completely in the summer, I'll be laughing all the way to the bank! :D


mwalsh, I would predict that you could top 30kwh/day *easy* in May or Aug. Your system is 50% bigger than mine and I got 26.6kwh in Aug this year. Your roof pitch is 20, like mine, so May or Aug gets the most direct sunlight. Although June gets the longest day, here in the OC, we get that June gloom Inversion layer in the morning so it suffers a bit. Aug gets some inversion too, and it's hotter during the day, so efficiency is slightly less.

Now that I will be getting the LEAF, I want to expand my system...but no more roof space :?

mwalsh, my peak production on a sunny summer day is 33 kWh. I expect that you should see about 40 under same conditions.

occ, re your comment on summer inversion layer: That's really only prevalent during June, for the most part. May this year was really great, but that isn't typical. But by July and certainly August, you can rely on many sunny days, with sun all day long.

You folks may also notice a temperature effect. Very hot days are not kind to solar PV output. It won't be much, but you might see a 5% degradation versus the same date with a cool breeze blowing.

Updated my post with today's figure - a rather miserable 4.26kWh on a rather miserable rainy day. :cry:

Boomer here in AZ my peak was 35kw a day. I had 6 panel off angle but since then set them all south. I am hoping for 36 or more now this summer.

So far since my system was installed in late March I have 6,481 kWh total. I like to read it as 6.5 Mega watts from my Power Generating Station :mrgreen:

6.5 mega watt HOURS would be closer, right?

That's right on par with my output 3.08kwh with your system about 50% bigger.

Well, at least our panels will get the super-dupa extra wash cytcle treatment this week :D

I set up a public link for my system. I have a PC pulling data over a serial conection an forwarding to SMA... There is some pretty cool data in the Energy and Power tab Daily and Monthly. http://www.sunnyportal.com/Templates/PublicPageOverview.aspx?plant=aa5430d4-accf-4911-babc-fd81b3c21df7

Enjoy...

Mine was about 3.2 today.

Here's some production data from our 5.8 kW PV system:

27 SunPower 215 watt panels, at 25 degrees, facing due south
with a SPR 6000 Sunny Boy inverter
monitored with Sunny WebBox

November 2010: operated 28 days with average output of 30.82 kWh
Twenty-three days were full sun, 5 days were partly cloudy

December 16: partly cloudy until 11 am, then rain the rest of the day: 12.38 kWh
December 17: scattered clouds throughout the day: 27.12 kWh

During the month of November, our system made 256 kWh more than we used. Our electric company paid us only $ 0.032 for each kWh. Every year at the end of November our electric company pays us for unused credited kWh for the year. Now our extra kWh will roll over into the next month, hopefully saving up for the AC use in June - October.

See photos of our system at: http://randdsrayhome.blogspot.com/

Chris...,
I found a peak of about 5.2 kW production, which seems right for your DC panel rating.

A SunnyBoy 8000?
I did not know an "8000" model was available. I thought the biggest was their "7000" model, but that was 2 years ago.

Seems like a 5000 or even 6000 would have fit your panels better.

Did you get the extra inverter capacity for future expansion (more panels)?
