    Indeed, Mr Spoilsport ;)

    Most of my production is going straight back into the grid, gaining me nothing. For the greater good. Reducing our overall emissions and reducing the fossil fuels we are burning to produce electricity. If only every house and every office building would produce more electricity from solar than they use, just like me...


    After giving away a good portion of the exceeess electricity produced by your hard earned cash PV panels, after 1 year...you went soft and slow and gave up... just happy to give away for free...

    Love it @unkel !
    Now,just i go and take a cup of coffee and search for the threads where "everyone of us" was angry for lack of FIT progress...

    A reasonable FIT is win win for all parties. Home / business owners get a reasonable return on their investment and for the government it's an extremely cheap way to increase the capacity of the grid (which is needed as more and more stuff gets electrified)

    With no intention to offend you guys... how much you wanna bet "today" that we will not have FIT on these lands !??
    Ive generated 10MWh, giving away 2.5MWh for which someone got paid for... why change it !?

    ESB have no interest in it and will resist it to the bitter end.

    The only hope is the EU dictating it, which is quite possible.

    There is a private member's bill before the Oireachtas. I can't see it being defeated, so I'd say it's just a matter of time. I'd be guessing that it's probably 4 years away, because if it's passed (should do within 18 months) the legislation and regulations then need to be figured out.

    I have got a much more reasonably quote since (although for a smaller system) so I'll update this thread this evening


    New quote options:
    3.25kW array and 5.6kWh battery - 7,683 net
    2.275kW array - 3,707.5 net
    2.6kW array and 2.8kWh battery - 5,692.5 net

    I think it's between the two last options above, have to learn more about how our usage varies over the day to see which offers a better roi

    One megawatt hour produced since my current system was installed in February. Not bad :cool:

    System is expected to produce nearly 4MWh per year. The average Irish household uses 3.5MWh per year


    Nice one... real congrats !

    Going to search for my old DIY topic somewhere here to update it.
    BUT, sorry for lack of modesty...long way to go to beat my 10MWh,10,000KWh ... ;)

    Day 3 of being happy owner of my own 3.6 kwp PV system.
    So far peaked out 3.37 kw out of it on bright sunny day so pretty good output i guess. battery charges up pretty fast as well, but also depletes during night time, since ive got coolwex heat recovery water heating system that is quite taxing on electricity meter :(
    Havent seen meter moving much since PV install so that must be a good sign :D
    Solis inverter mobile software doesn't provide much info apart from panel output, state of charge of battery, household usage and Mr Grid sucking up my juice :) Any ideas guys can I setup solis inverter to provide more detailed info for likes of one above that rolion has?

    Still waiting on my grant to be processed but been told by installer that it shouldn't take longer than 4 weeks, so happy out!
    Massive thanks to niall for providing me with details of most competitive PV installer in Ireland!

    A competent installer who obviously needs to make a profit, but isn't out ripping off people, deserves a lot of business.

    Has anyone with solar PV installed linked it with a heat pump? I have a heat pump that the manufacturer has two versions of an add on that will turn it on for heating or hot water when an excess of power is available from solar. Like a diverter but not directly into the heating element.

    One version connects the inverter directly to the heat pump and the other uses a CT clamp to measure the excess. But I don't know anyone with this setup and would be very interested in this setup if i knew it worked well. Hopefully someone here will have or know someone with similar and have a view

    Cheers Stefs_42, PM received. It was indeed the installer I mentioned before. I contacted all solar PV installers on the SEAI approved list and he was the only one who came back to me with a reasonable quote and also the only one who engaged with me in a meaningful discussion, someone who knows his stuff well.

    I mentioned him in my thread here (with moderator approval):

    yea he appeared to me that he knows good bit about PV systems! also installers work very clean, no mess left behind. whole installation done within 1 working day! i would highly recommend him

    I have a Nibe. When I spoke to them last Aug they told me that it could only use the Solar power to heat an element for DHW... in effect a diverter.

    They did say they were working on a new system but ultimately you can’t really use Solar to drive a HP because stopping and starting a compressor as the clouds roll over will trash your compressor in short order. It can only be used really as a diverter to drive the backup immersion of the HP.

    Unless they have some new product out that works differently?

    I was looking at an EME 20 which in some of the documents states it can heat and cool the house with the solar excess. This is why i assumed it is using the heat pump and not the element directly. But the compressor start/stop issue is a good point.

    Did you speak to NIBE directly or the Irish distributor? I am finding it difficult to get an definite answer on parts of this.

    I spoke to the Irish distributor.

    You would need a massive Solar array to drive a HP with the excess. Most HP's would need ~2kW+ to run.

    How many hours of the day would you have that excess and the elephant in the room.... the hours when you do have that excess is largely in summer when you dont need the HP at all other than to heat water.... i.e. diverter!

    SolarPV excess and HP's are not a good match unless there is some new type of compressor that can take low rates of power. I cant see how it would work at the times you need, without pulling expensive day rate electricity when the clouds roll over and crucially without over-cycling the compressor giving it an early death.

    I'd need alot of convincing to connect SolarPV to my HP compressor.... you dont want that to die early in its life for a few measly euro's worth of electricity.

    With say a 4kw array with 4.8kwh worth of batteries would it not be better to just time the heatpump to come on during say mid April to mid October for a certain time of the day? The time could be adjusted depending on the month

    Basically when you know the batteries are almost full and at a time during the day when there is still usually sunlight that the heatpump will come on, it won't pull anything from the grid in that case and will instead pull from the batteries if needed. Depending on the day the batteries would likely have time to still charge. I reckon I could write a script to do it (activate a relay that calls for heating the thermal mass), just don't have any of the equipment or data yet :P

    The Nibe, and Im sure others, allow you to connect relays to it and you can control those whatever way you wish. So you could leave the timers off and just drive a relay, via software, based on what you see on your Solar excess.

    So, in theory yes, but April-Oct the HP is usually off except for heating hot water, which it does super efficienctly on night rate electricity.

    So, the savings involved would be tiny. A simple diverter, which is what Nibe offered me last year, would be just as good and it wouldnt involve increasing the cycle count on your battery... which is an important consideration for Li-ion tech.

    I just dont see an overall benefit of connecting SolarPV excess to the compressor even if it is technically possible.

    Did they say if this would just heat DHW or on a sunny but cold day also heat the house via rads of UFH?

    Did you add anything along these lines to use the excess or go for a battery in the end.

    All they had available last year was a diverter which sensed what was available from the SolarPV and it diverted that to an element in the tank.... nothing else.

    It would not heat the underfloor.

    He did say he was travelling to Sweden to see some new Solar integration thingy that Nibe were working on but I didnt get any subseuqent info on that. I think their plan was to provide Solar panels themselves and have some tighter integration built into their HP's but I dont have the fine detail.

    Thanks for the info on this KCross. They have solar kits on their .eu site now, I think I first seem their EME integration unit on the brochure for these. Not sure how much of the kit they actually make themselves.

    Hi, I got a quote a few days ago from a well known home improvement company that have recently (March) started doing solar pv. They were the only one of the three installers that I got quotes from, that called to the house. The quote I got was for the installation of a 3kw 10 panel system with a 4.5kw battery plus immersion diverter. Cost to me €8.5k after grant. The hardware looks good, 20 year guarantee on the panels and 10 year guarantee- 6000 cycles on the battery
    We have a night saver meter and last year we used about 1500 day units and 800 night units.
    We'd like to do our bit for the environment but I would also like to at least break even over the 10ish years before the battery needs to be replaced.
    We'd be doing an East West split and they informed me that I could expect in the region of 2200kwh per annum from the system v 2700kwh if we had a South facing roof. My own calculations suggest that the system would need to provide at least half of the night units plus some day units as well in order to pay for itself over the first 10 years anyway?
    I also have a worry about compromising our 60 odd year old tiled roof during the rail instillation.
    My question to the group is, am I likely to loose or gain in the long run?
    Thanks folks!

    thats a bit overpriced quote imho. i would suggest you shop around a bit more for better deal! im myself with only very recent install paid 9.2k before grants! (grant to be processed yet)

    my system:
    12x300w panels, (3.6kwp total)
    hybrid inverter

    3.5kw battery
    about payback time- i would not worry much. whole idea of living greener appeals to me more. im way more conscious where and when im using my appliences now! and this changed thinking on its own will save you money!
