    Hi,

    I just got my system design and proposal. We're in NJ and I'd like any feedback, ideas, suggestions as we're new to the whole solar thing.

    Size: 17.33 kW ( 15,690 kWh estimated production in first year, 90% energy offset ). I have a model S which uses about 25 kWh / day to charge for my commute. Our total average daily consumption as of last month was 40kWh and I expect that to go up to about almost 50 kWh during the summer with A/C and pool. Our cost per kWh is about $0.16....yeah....ouch....
    Powerwalls: 0 - even though we had asked them to include them, need to find out why they didn't include them

    1. Solar Power System - $49,376
    2. Pre-Construction Costs - $13,500 - They say I need to replace current roof, which is about 15 years old and showing some signs of wear and is probably the second layer of shingles on a 34 year old home so would be a tear off job.
    3. Upfront Incentives/Rebates: -$9,529 - this is due to NJ SREC credit. This I really don't understand very well. At a basic level I believe for every 1000 kWh produced, an SREC is earned which can be sold on a market. Right now, it looks like SRECs are being sold for about $220, so that should be about $3,300 for the first year alone. The contract seems to indicate that Tesla will give me the $9,529 credit but that's all I'm entitled to. Has anyone else dealt with this? Is there any reason I can't sell these credits separately? Seems like a sweet deal for Tesla.
    4. Federal Tax Credit: $14,813

    So, if I look at cost / kW as being $49, 376 - tax credit of $14, 813 divided by a rate of 17.33kW that seems to be about $1.99/kW. Am I thinking about that correctly? Seems like a good price. Main negative would be if they won't allow me to independently claim the SRECs. Can anyone tell me if I produce 15 mWh / year does that mean I get 15 new SRECs each year? so in other words if that's worth $3300 per year I can get that in perpetuity ( I do believe that SREC market will decline about $10/SREC/year, but still, even with that, over 10 years, thats $26,250 or $37,500 over 20 years ) which would go along way to covering any loan cost. The re-roof might be a little premature but I'm not too worried about it. Might be able to save a few dollars if we got quotes from other contractors but then again, this is NJ.

    One last Q. We had a guy out from Sunrun to give us a quote. he mentioned that it is illegal to store electricity residentially in NJ and so Powerwalls are useless. I can't find anything about that and Tesla said no but has anyone come across anything like this or was that just Sales BS? Wondering more since Tesla didn't include Powerwalls in quote. Also wondering if it's worth getting Powerwalls vs relying on net metering for cost savings at night time reliance on utility company. Other reason was to have a way to deal with power outages but could also do backup generator and save a few K.

    Again, any input is welcome.

    I don't have solar (neighbors have too many large trees), but there have been discussions of this on the Tesla Owners of NJ google group:
    Google Groups

    I'm pretty sure I even read a post from a member with solar from Sunrun + a powerwall. (look for 'Solar')

    That sounds like a great price! Powerwalls are 100% fine in NJ. I'm in NJ and just had 3 installed last week (there is a huge backlog though). Also, the NJ SREC program is closing to new installs very soon so don't delay. Also, don't let Tesla take your SRECs. Assuming the SRECs avg $150 this is super conservative for NJ) over the 10 years you are allowed to claim them... You would earn $22,000 from SRECs alone! Take a look at SRECTrade.com they handle all the details of your SRECs for a small fee ($14 per SREC)

    Good to hear from a fellow NJ person! Mind if I pick your brain a bit more?

    How long have you had your system? Is it performing as you expected/as it was sized? Do you have PSEG or JCPL? Do you take advantage of net metering? If so, how well does that cover your nighttime needs?

    I'm debating about going with a backup generator vs powerwalls for coverage during outages, seems like between cost/wait for powerwalls vs generator plus benefits of net metering it may push me towards generator. What do you think?

    I'm just over the border from you in the Hudson Valley in NY. I had a 6.6kw system and 2 PW's installed last November. For me, it was all about having a backup power option. Strongly considered an automatic LP system but there are so many negatives associated with going that route. I could not be happier with the decision to go with the PV/PW's. Solar production and offset has been far better than expected. Systems performs exactly as advertised. Happy to answer any questions you have if you want to hit me off line.

    Orange and Rockland, i'll try and answer any questions that you may have ... In my experience the Tesla crews serving our region are top-notch.

    I noticed you have powerwalls so you might not have to worry about this. However Im trying to understand the net metering in the area. I was wondering how the net metering worked for Central Hudson but seeing that your in Rockland/Orange I dont think they are your provider. I want to know if i put in 1kw do i get back 1kw with net metering. Or do I get back a smaller percentage.

    i'm almost certain that it is 1 for 1 for me with O&R. FYI, i am 3 months in a row now without an electric bill and have about $100 rolling credit from excess production. could not possibly be more pleased as this was icing on the cake for me. our original use case and justification was almost entirely a backup power source.

    One issue I’ve discovered is that our utility caps net metering at 10kWh. I usually charge my model S at night which uses about 25kW out of a total daily amount of 40 to 50 kW, leaving me with a likely shortfall of 15 to 20 kW.

    This will impact savings for sure. Any ideas here? Probably powerwall but that drives cost up

    $2.85/W seems to be the new Tesla online price point for your area. A decent price, especially for an operation you know will be around in 10 years if service is needed.

    The Sunrun sales comment about Powerwalls being illegal in NJ is nonsense. Perhaps they were confused and were talking about charging a Powewall from or feeding to the grid?

    No idea about the NJ net metering cap, but I'm gonna look into it now. Interesting.

    I don't see any statewide cap in net metering in NJ. Perhaps your utility caps the array size at 10kW? That doesn't seem possible/rational though.

    This estimated production number seems awfully law. What's the proposed orientation of the panels. It should be at least 20 kwh, I would think, even in NJ.

    I may have been wrong about net metering cap. Link to JCP&L info:

    Retail Interconnection

    I though they limited residential to < 10kW inverters but there's a second level that's for < 2,000 kW that looks like I should be able to join and get full value, though there is a fee.

    Does anyone else find this clear as mud? How do you figure all this out?
