    I got a quote for a 5Kw system (14 x 360W panels) and a 3.5Kw battery. Cost after grant is c. €7.2k

    We have a garage that is south facing so all good on that front. House is currently been rewired so it might be the chance to get it done now will all the wok is been done.

    What should I be asking for when dealing with the companies?

    Is there any recommendations for companies out there?

    I have a Nissan Leaf also. The sales man says he we should ditch the battery and use the leaf as the'battery'.

    He needs to ditch about €2k off the price when he removes the battery from your quote.

    To utilise the Leaf for dumping the excess you need to have a smart Solar integrated charge point. What have you got right now for charging the Leaf?

    He is quoting battery at 3k

    Without the battery its €7.2 less the €1.8k SEAI grant

    Get more quotes for non-battery systems. Battery systems only barely make financial sense at the moment and it is looking like we will have a feed it tarrif in some form this year which will reduce the argument for them significantly.

    Any recommendations on suppliers?

    I went with the "solar as a service" supplier who I can't fault and was by far the most competitive price I could get (before Xmas). It is worth gettting an indicative quote off as many suppliers as you can, it's the same questions they each ask so once you've done one it's not much hassle to get more quotes. The discrepancy in pricing and some of the outlandish quotes you'll get are eye opening.

    Sorry to drag this up again.

    Have a few quotes in. Getting conflicting accounts of 5kw vs 2.4 kw. There is about €1800 in the price.

    Where is the sweet spot in terms of panel size?

    Depends on your usage and will change once the fit is announced. If it's low, a smaller array (which you use most of the generated power) is likely the sweet spot, if the fit is higher, more panels the merrier

    Seems high, the pylontech 3. 5kwh battery can be bought by you for 1300, so he's charging over double that. Chancer.

    Is it easy to buy a battery after the fact? I have a battery and on days like today it full already, wouldn’t mind adding a few more KW storage to it

    For pylontech it is, more or less plug and play, few cables to hook up between the battery units. I can't speak to others as have not looked into them. Your inverter must be a hybrid one of course, but if you already have a battery that's the case anyway.

    They also weigh a bit, hopefully your first one was mounted with a double bracket so as tails said its a simple plug and play cable hook up.
    If yours was installed with a single bracket then you will need to get a double bracket.
    They also fit in standard sized comms cabinet...

    The hybrid Vs standard inverter will make up some of that 3k though

    I'd say after fit comes in there might be second hand batteries at more competitive prices on the market as the benefits from a battery will be diminished. If you have a Pylontech battery it should be straightforward to add another, if you have a cabinet and space for 1.

    I have no idea on prices currently.
