    Looks like I missed the party, but I just wanted to chime in that originally, I too, had planned to set my Anniversary to March as GPE has recommended. But the more I looked at my usage and production patterns, it actually made more sense for me to set mine to Dec 31/Jan 1st. In my case, since my home is all natural gas, my main electric usage is HVAC April-October.

    In 2019 my array offset approx 91% of my usage (System Production:12.34 MWh; Consumption:13.53 MWh).

    Generally Feb-June I make more than I use. And in July-Jan, I use more than I make. I start banking MWh in Feb through June, that then carry me through October-ish. By Nov, all my banked credits are used up. Usually in Feb, I start banking for the next Summer.

    If your arrays are inclined more than mine (mine's only 20%) then you'd make even more production in Winter than I do.

    If I had set my Anniversary to March or April I would have missed that winter/early Spring production. Granted, it's not a lot of production, but I'd hate to "through it away" at wholesale rates.

    Our annual reset is fixed at the fiscal year-end for my utility (April 30th) and there is no option to change it. That time of year is when we have the biggest reserve of the entire year (3000 kWh on average) and it's just as we enter the heavy summer cooling season. I would much rather use the banked energy than get wholesale value for it. By being mindful of the thermostat in the summer, we do make it though the entire year with no net billable energy but it would be nice to set the A/C a notch lower June-August.

    My reset is end of March. I could have used end of April, because I might need the
    reserve from the previous summer to heat a couple buildings. However I have
    been able to generate just enough energy to avoid buying any every April so far.

    In my case, since my billing date is also the last day of the month, the person I spoke to advised setting February as the anniversary month, since theoretically February should be more likely to be a deficit generation month and March would be likely to be a surplus month, so I should thus avoid getting cashed out for watthours I'll be using in AC months

    Thanks for the data point!

    My cycle ends about the last day of the month (30th or so) so I guess technically I could have used Feb. as my reset to capture all of March in my NEW solar year, but I doubt it'll matter much. As I understand, as long as you're using up all of your solar bank BEFORE the next solar year you won't be getting paid out either way so considering the low production of Dec-Feb I'm sure it won't be an issue in my case.

    Hey, did you happen to reset your solar anniversary yet?

    I just called JCP&L at the GPE provided number of 800-662-3115 and at the prompt was transferred to billing.

    I stated I was calling to "change my solar interconnection month for purposes of net metering", and the agent was clearly aware of the nature of my call. She asked what month I would like and I stated March as recommended.

    I'm assuming this annual solar review takes place on your typical meter reading date, but I don't know for a fact....maybe some of our local veteran members can confirm. I'm guessing March would mean at the end of the Feb. reading date to include the full March statement period.....

    Anyways, I was given an official notification case number for reference and it seems like that's it, no other notification via mail or such as far as I was told. The request is sent to the appropriate department and the change is made.

    Looks like today is the last actually sunny day for December here in central NJ! PVWatts had estimated about 497kWh for this month and I'm probably on pace to only get to 325 or 350kWh if lucky (currently at 267kWh for the month). In November my production was 612kWh against PVWatts estimate of 567kWh.

    For January the estimate says 576kWh and for Feb its 705kWh which I am having a hard time believing will get anywhere close to, especially Feb of only 28 days! Or maybe there is a higher concentration historically of clear days then and the days slightly longer then.
    As the PVWatts help screens state, actual system production over any 30 day period will probably be ~ +/- 30 % of what the model comes up with.

    FWIW, if I modify the PVWatts system loss parameter so that the model exactly matches my system's total output since 10/17/13, the (actual running 31 day system output)/(PVWatts modeled 31 day output for the same period) has max. and min. values of +30.23 % and -35.56%. The population std. dev. is 9.75 %.

    The running 365 day actual totals are +5.30 % and -3.93 % of the PVWatts 365 day total, std. dev. is 2.22 %.

    Your results will be different, but the ~ +/- 30% variation between model and actual over any 30 day period is to be expected.

    Models are for system design. A model cannot predict system performance with any more reliability than the weather can be predicted more than a few days ahead.

    For the same reasons that climate is easier to rely on than weather for long term planning, the longer the period of analysis, the closer and probably more accurate a model will get to a rough estimate of a system's output.

    @NJturtlePower, how's your system been doing in December? My production fell off the cliff, even compared to November's 794kWh, and never mind the peak in August at 1.7MWh - three weeks into December and it generated a whopping 147kWh In August on a perfect day it made 76kWh IIRC in a single day. My problem here is even couple inches of snow will stick around for 4-5 days since I'm pretty high up, so much of this month my panels are covered. Even after the warm day we had yesterday, four of the panels are still covered in ice. Brushing the snow off is out of the question for me.

    I might as well call JCP&L now and reset my anniversary to March. Should it be on March 1st or April 1st? I'm guessing March 1st.

    For some reason I can't tag forum members any more, so I figure I'd ask you in your thread. Have a great holiday!
    As others mentioned, the first 15 or so days of Dec. were terrible between the cloudy, rainy and snowy days in most of NJ. Luckily, the last week has turned around pretty nicely, although I'm still less than 50% to my estimated 805 kWh monthly production.

    In better news, I successfully traded my first 3 SREC's for $648 last week. Starting to feel like a real income source. And although I haven't been able to bank anything just yet starting so late in the season, I can't complain with electric bills totalling only $45 (Oct) $8 (Nov) and $8 (Dec).

    I have yet to reset my "Solar Year" with JCP&L but i'll get to it soon... March 1st it is!

    Have a great Christmas/Holiday/Winter Break to you and all the others following along here.

    [QUOTE=sunpoweredev;n409495]Where I am, summer is typically 6-8 degrees cooler than say NYC, and we pay it back in the winter when it's the opposite, too bad I can't have it both ways./QUOTE]

    You can. Do what I did. Move to San Diego.

    @jordgubbe @macaddict you guys will be at least 50% of November. As of right now I'm at 1/5 my November production lol.

    Where I am, summer is typically 6-8 degrees cooler than say NYC, and we pay it back in the winter when it's the opposite, too bad I can't have it both ways. So even a small amount of snow will stick around for a while, and that's assuming the sky clears up. In fact, a lot of times when we get an inch or 2, I drive down this hill and there's nothing at all.

    At least the sun will start getting higher again now.

    I approved your posts. I am not sure why there was an issue.

    Hey, my solar edge stopped communicating on 12/16 I just noticed. I sent a support request. The second meter they installed is failing... the screen is degrading. Check to see when the last time SolarEdge portal was updated.
