    So by all means, do some proper sums, but do invest in renewables if you can and the figures make (at least some) sense!

    TBH it's primarily an environmental choice. Have been slowly making all the right changes - A3/Heat Pump house, little/no meat, grow a lot of our own veg/source from local farmer, don't fly, EV recently, reduce/reuse/recycle. Last up is Solar PV and I'd say it's hardest per my post in PV quotes thread - A3 means no grant so the sums are a bit harder to justify even with the environment as primary motivation. This thread has actually confirmed my sums so very helpful. Will probably get it in over the summer with a significant dose of DIY.

    Eh? August would be at least 30% higher than Sep no? Unless he gave the August generation stats but not Zappi/Eddi.

    Yeah it was before the myengei app update. Was being optimistic!

    Yeah if you do a good bit of DIY the sums would make sense. You just need to have a keen eye, shop around and don't commit till you get a good price.

    @DrPhilG


    I made a mistake, your install is 6.2 and not 7.2kW. So 2.8 S and 3.4 W assuming a good 35 degree tilt, PV-GIS gives 5200 kWh. No way you save 900 Eur on that. Even if you used every single kWh for day-time use you'd need to be paying 17.3c per kWh. So 900 is simply not possible. Energia's new plan is 14.22c but even if you were on the older 16c plan the theoretical max you can save is 840.

    Glad to see some common sense when it comes to financial savings, I had plenty of installers telling me I'd save a grand a year and when questioned was told prepared by accountant and using 19c day rate, enough said.
    As an accountant myself it beggers my belief when I see such little common sense application and/or trying to fool people, does my head in.
    Looking at previous years bills is a total waste of time as usage/rates etc can be so very different.

    Totally agree that just normal base load should be savings at day rate, you should know your base rate as it's an easy read of the meter a few times a day for a week or so, base loads varies very little you will soon see.
    Everything else should be night rate as charging your EV, washing machine, dryer, dishwasher etc should all be operated at night rate.
    I saw one guy try to be clever and just divide the day and night rate and use an average but remember 9 hours night rate and 15 hours day rate so you cannot use a simple average, at least you should weight it.
    Also, if looking at Payback everything needs to be included, don't go leaving out that BER cost.

    I'm brutal with my savings, all at night rate and just 4 units base load at day rate in Winter, no point in fooling anyone especially me.

    Now the Sun is better it's a case of experimenting and moving likes of washing machine to around 11am, dryer too etc.

    Exactly. Its technically not possible. Not sure Phil is up for accepting that though. :)

    The debate about switching providers is irrelevant. Comparing bills from previous years is irrelevant.

    You can only go off the stats from your inverter (or MyEnergi app) and decide how much of it is to be calculated at day rate and how much of it is night rate (car/eddi/washing-machine etc) and thats your ROI.

    Everything else is irrelevant.

    Funny thing is if I was to tell my wife about the ROI she'd probably still ask whats the difference between the bills!! Difference between night/rate, changing supplier she doesn't care about - just the overall difference be it solar or whatever :)


    One nice feature of my system is you can populate the prices and time periods and it calculates Feed-in (obviously zero so far), self-consumption and load shifting. (only installed end of september and only started load-shifting part way through january when i moved to day/night rate)

    If you don't have an EV, is it still worth moving to night time electric?

    3300 kWh approx usage per year.

    Paying 13.75c with Energia for daytime units.

    Probably not but you'd have to see what your night time usage is and calculate from there.

    Its only worth it if you can use 30%+ of your units on the night rate.

    If you are working from home it's pretty hard to hit the night rate percent to make it worth your while without an EV. As it is with 3300kWH your consumption is on the low side. So unless you are confident you can move much of your consumption to 11-8, I wouldn't bother.

    for 3300kWh per year with normal rate at 13c, but day rate at 14c, night rate at 8c and a €50 higher standing charge, the break even percentage is having 41% of your units on night rate. That's a lot if you don't have an EV, I wouldn't bother

    3300 (x * 0.08) + 3300 (1-x)*0.14 + 50 = 3300 * 0.13

    x=0.41

    And given that night rate is only 9 hours per day, without a serious effort running almost all of your dish washing / clothes washing and clothes drying during night rate, you'd struggle to make that 41%

    Dec 2020: 63.4 kWh
    Jan 2021: 78.5 kWh

    Highest day: 28th 13.4. Lowest: 7th: 1.2.
    Self consumption: 98.6%.
    Self sufficient: 25.8%

    Huge jump on January. Feb daily average of 6.7kW above January's highest day of 5.7kW. East panels not getting full sun yet due to shading.

    Battery started nearing 100% in the last week so Zappi has come into play and the car now runs on sunshine. Zappi doesn't seem to turn on with Eco++ for the surplus 1.4 kW required as the inverter appears to prioritise house battery over Zappi so I've used Eco+ setting. I can get a steady charge going from panels with top up from house battery if any clouds pass by. It's a bit of a manual process as I turn on when battery starts getting to 50% to ensure I'm not exporting later when battery is full but the car won't take surplus below 1.4 kW.

    Gonna compare to last year from now on:
    4.8 kWp E/W. 2.4kWh battery. 24 degree slope.

    March 2020(kWh):
    Expected: 291
    Actual: 381

    Best day 22nd: 18.6
    Worst 9th: 2.3

    Imported 200 units from the grid and exported 99.


    March 2021(kWh):
    Production: 332.4 (291 predicted)
    Consumption: 711
    Import: 404 (180d, 224n)
    Export: 25.6 ( pred.)

    Best day: 29th: 19.1
    Worst day 3rd: 2.1

    Last March was absolutely brilliant. But this one wasn't too bad ether. After a slow start things started ramping up after the 10th. Exported around a quarter of what I did last year thanks to the Zappi. Apart from a small charge on the 15th have only charged the car from the sun.

    March 2021 :

    First go at this with 16 panel 6kw south facing system and hot water diverter going live on March 16th on the south east.

    Generated 226kWh
    Consumed 116kWh
    Exported 109kWh
    Imported 110kWh
    Eddie 66kWh
    Green 51%

    Best day March 17th 29.4kWh
    Worst day March 28th 4.1 kWh

    Overall we could have managed usage a bit better but not a bad start & great to have so much hot water. A lot of export to the grid and am hoping FIT and an EV will cover a good bit of this. Future proofed while the grant was still going but held off on a battery. First electricity bill due soon.
