    Interaction of PG&E NEM-2 and EV2-A

    Billing\crediting is done in money not kwh so avoiding usage during peak is important.

    I replaced 4 of them with wafer lights in a little under an hour. Abandoned the old cans in the attic and wafer lights fit in the old hole perfectly.

    Looks like exporting rate is high during peak for all of september and close to retail in aug. If nem 3 customer eligible for VPP might be almost $5\ kwh total compensation during flex alert. https://willdan.app.box.com/v/2022CPUCAvoidedCosts/file/1015321747620

    CPUC NEM 3.0 discussion

    Until new rates are made for everyone which will have a fixed rate component and a lower volumetric rate the E-ELEC rate will be used for new solar customers. The E-ELEC rate should become effective in December for non-solar customers and everyone next year. Basically EV2 with $15 monthly fee...

    The E-Elec rate potentially seems very similar to EV2, slightly lower but with a $15 fee, initially seems like it would have been $25 but cpuc prefers fixed fee. E-ELEC Rate Component Price Monthly Fixed Charge $15 Summer Peak (4 pm – 9 pm) $0.43340/kWh Summer Part-Peak (3 – 4pm, 9 pm – 12 am)...

    New Tesla orders - More panels / same inverter

    1.26 ratio will have very little clipping, if not all in same direction likely no clipping at all. Mine is at 1.36 all south and I lose maybe 1-2% per year and intend to bump that up to ~1.5 eventually to help during non summer afternoons.

    CPUC solar decision?

    A new rate with "highly differentiated time-of-use rates" is supposed to be created as part of this, the current EV2-A plan is listed as also acceptable. If I optimistically assume the new rate plan will remain at about $0.18 like ev2-a assuming it can be self consumed or stored in batteries 1...

    My install price increased because Tesla changed from 8.16 to 8.5kW

    IIRC some people got a free upgrade when they switched from 315w to 340w and I think the contract says they could give you up to 10% more if they substitue equipment, have you tried calling to complain about price increase to see if they might give you the new panels at the old price?

    Modification question

    Tesla inverters seem to have a max 1.4 ratio so it could be worth asking for 10.88 vs 10.2 if the 2nd inverter would be helpful to your layout.

    Selling home with owned PWs and rented solar

    If I was buying I would at minimum want a $2500 + transfer fee as a credit from you to take over the rental and I would imagine many would assume it similar to a long term lease and be turned off so its likely best to at least the free removal one taken off if not both. It would be interesting...

    Tesla app usage doesn't match SCE bill

    Using a Credit Card or Paypal to pay for Tesla Solar

    I have charged 20x my limit before in a month on numerous accounts and received full points with the exception of citi double cash which gives 1% of the rewards on payment as long as its equal less than the balance so you would get 1% vs the 2% on that card.

    How long to get a design?

    They told me 3 weeks , on the 21st day I emailed the advisor and received updated design 2 hours later not sure if coincidence or if it might have been done sooner had I asked sooner.

    PG&E changes 110% of usage rule to 100%

    It looks like they reduce the expected generation per cec kw from 1664 to 1500 which is a 10% decrease so doesnt that cancel the change from 110% prior usage to 100%. before 4kw system x 1664 = 6656 generation / 110% = 6051 required usage prior year now 4kw system x 1500 = 6000 generation /...

    Elon tweets: Solar Roof and solar panels will only be sold integrated with Powerwall

    You should be able to use 3.32 kwh x sq feet instead of actual usage on a new home so if the new home is in the 3000sqft range you likely wont even need to have a planned annual increase amount.

    Strange call from Sunrun asking me about my true-up.....

    Prob looking for people who increased their usage after getting system and they could "take care of" the true up by roling it into a lease on a 2nd system.

    Going rate for solar panel installs?

    I only found one contractor out of santa cruz (advertises on craigslist) who would install for a (non exorbitant) fee plus equipment rather than a package deal. Think he quoted me 3500 labor for 5.5kw system install although could be less since that included the inverters and he was traveling...

    Is 1 PowerWall better than No PowerWall?

    Looks like the average price delta is about 27c. If a third of your usage is during peak times that would be about 6kw a day which should almost always be more than generation from a 8kw system 27c x 6 = $1.62 * 360 days a year = $583 At a 8k after tax credit installed cost your breakeven is...

    Tesla Solar Loan Craziness [Beaverton, OR]

    You likely avoided about $3-400 worth of interest so far which you could see as compensation for the extra inquiry. I have had 20+ inquries before and still stayed over 800 so not that big of a deal.

    Adding additional solar panels

    if you have only 6 327w panels on a 3kw inverter could you just stick another 6 on there and have ~1.3 dc:ac ratio?

    SCE NEM 1.0 grandfathering when adding more panels?

    I think you can get a 2nd meter and have both the old system on nem 1 and new on nem 2 but cost will be likely be more than just paying your 2-3c nbc especially if your 3 powerwalls allow you to have low grid usage

    How did you get your SolarEdge Physical Layout

    If difficult to take photo of serial couldnt you cover 1 at a time with cardboard or something using a stick on the ground and rotate every few mins to identify the module based on zero production on solar edge site during the time frame

    Are tesla solar panels this delicate? :)

    Disappointed by safety systems impact on production

    If your system has about 500 solar tiles and each set of 10 has a minimum of 4W the minimum for your system to start would be around 40W per string or 200W total, is that tha amount you are missing? Hopefully it wont be an issue in a month or two when days are longer\ more sunny. I am pretty...

    2 Powerwalls + "Free Nights" Plan...can they pay for themselves?

    If you fully utilise one powerwall daily and get say 11kwh out of it you save $0.78, if you go with another provider that waives the TDU during free nights you increase your savings to about $1.28 per day. 5 powerwalls look to be around 44k with taxes from tesla and would at best save you $6.4...

    TOU-C or TOU-D for Solar without PWs?

    My net usage \ net export is almost always less than baseline as I have low usage and only 5kw system so it washes but the amount over should get the full rate. I rarely use AC in summer the higher summer rates allow me to use ~9mwh per year and generate 8mwh per year and still have no...

    TOU-C or TOU-D for Solar without PWs?

    its just dollar credits, c was better for me in most senarios I tested since solar offsets some of the summer peak where d hardly does and the winter rates are almost the same peak\ off peak. The Pge rate estimator in your account can give you an estimate of both plans costs if you just got...

    Exact cost of NBC/ kwh?

    I think I figured it was suposed to be 2.1c but last month I exported 154kwh and net NBC was $1.94 which would work to 1.26c althoughI think medical baseline exempts the wildfire charge so that might make up the difference.

    PG&E/EBCE interconnection agreement question regarding system size vs. actual usage

    I think PGE formula assumes panels are\ mostly are south. PTC ratings of my panels is 90 and 93% of name plate, not sure what ptc for solar roof tiles are but might get you in right ballpark. Delta inverter cec efficency 99%. 11.2kw*.9*.99*1664 =16600 KWH
