    No? Unless I'm mistaken, it's still 21, but if your a trade, VAT Registered, you buy it, claim the 21% VAT back, then charge your customer for install and charge 13.5% on the whole thing.

    Got trade account and few quid off listed online price.

    21% means luxury item then not just electrical?

    According to revenue.ie solar panels carry 21% but to supply and install is only 13%

    Generally 21% - thing
    13.5% - Service

    PV panels only 5% VAT in the UK


    Anyone buy from the continent?

    Looks like delivery between €300-400.

    Cheaper to buy here. The two main wholesale providers (who also supply retail) are solartricity (Irish owned) and midsummer (British owned), you take your pick ;)

    In the event of a power cut which is frequent where I live will a 5-6 kw array keep the basics running during the day like wifi/internet/computer & fridge if the sun is not shining?

    How long approx would a 4.8 Kwh battery power the same in the evening?

    A grid tied inverter won’t output anything if there is no mains.

    Others will know more on here but I think some may possibly have the option connecting one output such as a socket for use in a power cut this wouldn’t be part of your normal consumer unit.

    According to the sales guy the batteries will power the house once isolated from the mains during a power cut so I assume that's DC from batteries/panels going back through the invertor to supply the house AC.

    Is this possible with a hybrid invertor or is there more kit needed?

    Thanks.

    All depends on how much power you use!

    Therein lies your issue, get that in writing, also remember the amps/voltage from the batteries will be limited so e.g. you won't boil a kettle.
    A typical 2 battery Pylontech 2.4kWh battery setup (so 4.8kWh) will max out at 2.2kW consumption

    I will double check Slave1


    With everything tripped out bar bare essentials, TV/WiFi few lights & fridge say even 500W a 4.8 Kwh battery should last 8 hours.

    I would be happy with 6 hours.

    4.8kWh is the rating of the battery, you will not have access to 100% of it, it is typically only 80%-90% accessible.
    That gives you 3.9kWh to 4.3kWh accessible so would reduce your 8 hours

    Standard setup won't power the house when grid power goes off. There is a switch that isolates the solar panels / batteries from the inverter once the grid power is lost. This is because otherwise the grid upstream of your house could be live when the power workers would expect it to be offline.

    The inverters have a seperate off-grid connection that allows you to take power
    from the panels and battery but you cannot use this to power the normal mains circuit in your house. Simplest you could do would be to have an extension lead from the inverter to what ever you wanted to power. A previous poster did show more complex arrangement that isolates the house wiring from the grid via a large switch and that brings the inverter back in.

    That salesman sounds like someone you should be very wary of if he's spouting things like that... it's a big warning sign - as another post said, make sure you get all the promises in writing..

    I'm guessing a lot hybrid inverters with battery backup mode but how you use is key, so for instance some installers offered to just have a dedicated set of sockets off that. in power outage plug what you need into that (as other posters mentioned as long as output from battery will cover it - maybe you can't even run a kettle!)

    The next option I got was a sub board. I'm not exactly sure how this is wired up but my understanding is a small board is installed with a couple of circuits from your main board - eg lights. (where i'm lost is how this is powered when you don't have a power cut! as I would assume the backup sockets only work when the power goes off and not all the time ???)

    This option is more complicated and basically you get an isolating switch put in before your existing fuse board. In normal operation its set to grid mode thus you get power from grid and/or panels/battery. In case of power cut i switch that over to backup mode which disconnects me from the grid and instead all power then is coming from the backup supply of the inverter. (as far as i recall when i enable this mode the connection between panels and hybrid inverter is also reestablished hence i can use both battery and solar power -- plan to test that but not when wife is around to complain about all the time clocks needing to be reset!!!!)

    That's interesting idc.

    Have you tested your setup in a power cut or just out of curiosity to see how it would perform independently?

    I want to test that to be sure. When installed they showed me backup working but can't remember if I also saw panels still feeding battery/inverter. I'm 99% sure that's what installer told me as he explained another customer had power cut during summer but his battery didn't have much charge, so he turned off pretty much everything to reduce his consumption as much as possible and then let panels fill up the battery for him to use later in the day while powercut was still in effect.

    Not true.

    You can put a changeover switch ahead of your consumer unit that has grid and solar inverter backup power as options.

    Sorry, I worded it badly.

    Typically, you can't do it I guess might have been better - always ways to do things though!

    Good grief - how crude could you be? Pretty much would rule me out of ever using your company if this is how you behave and as another post has said... if you have four grammar errors (including not capitalizing your own name) and a spelling error in a single sentence post I'd dubious how much effort you'd put into doing work correctly.

    There are people on here (not me) who had systems installed by this person. And are quite happy with them.

    I didn't listen to the radio interview posted a number of pages back regarding Eamon Ryan and supposedly FIT only be available to certain BER rated properties. Anyone know what the thought process behind this would be.

    Covered quite thoroughly in this thread : https://www.boards.ie/vbulletin/showthread.php?t=2058149744

    TLDR 2 tariffs proposed - both are to run, a subsidised one and a standard one
    Subsidised - Limits on export (prevent cash for ash kind of thing), BER ratings, installs after 30th june 2021

    Standard one that goes on the wholesale rate.

    The thought process is that you spend your money on other more beneficial things before you spend it on Solar PV. e.g. insulation, heating controls etc.

    And its not a new requirement as such, since the existing Solar PV grant has a BER C (post-works) minimum requirement in place already.

    ;)Yeah had seen the previous C rating. The house was built in 2000 and would expect it to reach a C after PV install as boiler/ controls were upgraded along with with some wall & attic insulation but not sure if it would get a B

    There is no B requirement at the moment. The consulation document talks about possibly increasing it to a B over time but that might not happen. Its a consulation document, not policy yet so object if you think B is not reasonable.

    Can anyone give a ball figure of what is a reasonable price based on a 12 panel/4.2KW system, no battery or diverter, on the roof for a standard 2 storey house, just a standard use it or loose setup until the FIT comes in of course ;). I have priced up the same kit required in SC and comes to approx 3K+vat if I was to go the self install route. So looking what the difference would be if I went the contractor/grant route. Thanks

    €4500-€5000 after grant is what you should be aiming at via an SEAI registered installer.

    I have a quote of 4200 for 7 panels, less grant its 2400 have ask how much for extra panels was thinking of 10 panels myself. Think with covid everything is stopped at the moment.
