It's a pity we don't have net billing, would mean no need for battery storage! With all signs indicating that we're going to struggle with power this winter it feels like the CRU / ESBN could do more to incentivise micro generation by providing meaningful feed in tariffs. While it won't solve all our problems it would help with grid stability.
@donalfalvey145

Hey Philip. It's lot better in Ireland than here in the UK where the feed in tariffs have been reducing. The best offer is currently Tesla (?) who offer 10-12p per kWh against an average price of 28p to buy 1kWh. The standard electricity companies pay between 1.5-7.5p per kWh. From what I can see Flogas are offering 20c per kWh and charge @ 30c. That's pretty good. Most likely what will happen is the SEG will reduce as the PV roll out continues in Ireland. Lets face it, the electricity supply companies do not want you becoming self sufficient. Unless they can buy electricity from you at a lower price than the wholesale price?

Good intro vid. I'm not convinced that the Eddie makes any sense while you get money to export. Of the people I know who have it it doesn't provide enough hot water at the right times so gas is required to supplement and their export drops to near zero. They switched it off and export rate went up and gas use remained the same. If there is no export rate being paid it's a good idea.

The system you have with Ginlong (Solis) inverter, Eddi diverter and Pylontech batteries is extremely popular in Ireland. Often there is also a Zappi for charging electric cars. The main difference with a lot of installs is that not everyone goes for the batteries. The batteries were a no-brainer in the days before feed in tariff but nowadays they are valuable as a source of backup for when the power goes. Does your inverter have a backup outlet so you can run from the battery when there is a power cut?

Hi John, I have to say, having seen what is left on the wall from other installers etc, you do VERY CLEAN work - restores my faith in "professionals" lol. Question: Is it possible to put the automatic grid-tie cut out switch downstream from the internal grid within the house? ie. Can you isolate the panels, battery storage, inverters etc and put the back feed to the grid as what would effectively be a spur load off your own little generation / storage island? Would this sort of option then also require an automatic switch - similar to those used with stand-by generators on the feed to your house panel? So... Panels -> inverter ->battery storage ... this is a "unit" then a load applied to that generation source for the 6.5KwH grid tie feed (with the automatic isolation if the grid goes down) and a second load ( second inverter even ??) to your house panel feed switch... that switch then being either a smart switch which will draw off your panels first and fill the load from the grid and/or pull only from one or the other. I guess this is then a 2 source, 2 load, redundantly isolated system.....

Recently I made enquiries about solar panels with two providers. One of the providers is through my electrical company and will allow me to pay for the system over 3 years interest free and they recently did a survey and they dont recommend the battery but the system would have 10 panels and the eddy. My usage is under 2000 units and i would use a lot of that on my free day which is Saturday on my electrical smart meter plan. My house is in the North East and was built in the 70s east - west facing, it has a duel heating system open fire with back boiler and oil heating system both heat the water. However this is where I start to get confused my electrical fuse board is from about 1979 the surveyor seemed to think it would need changing which I knew and i am willing to do but that the house may have to be rewired . I also contacted my own electrican and he will be dropping into me soon to check the wiring and to see if it is the case . What would you advise on this and would you think it is worth my while ?

We can plan the orientation of the extension to meet the needs of capturing the sun, but would a typical 400 sq ft extension have enough roof space to hold a system? Also, apologies but non technical, when you explained the "grid trip switch" piece, and you said if the grid goes down the panels are isolated etc. Do you mean that the system would no longer continue to power the house etc? Like an off grid scenario? Are there systems that would allow that or does the ESB have a blacket rule? Many thanks and you have a new follower! Cheers, Peter, Vancouver Canada

the single battery is joke for the inverter and panells. it has only1.2kvah charge an discharge rate so cant pover your apliances. in summer you get 20-30kwh a day. you already spend more than 1000eur extra for inverter and cabinet so the price of battery is very little extra. have similar system for 3years in wexford. from march till october no electricity from grid bud you need bigger battery (much cheaper for me buy directly from UK) get te pylontech 5000kv version. in winter charging battery for 12.5c night so dont use 52.7c day rate. very profitable investment.

I can add batteries as needed in the summer, I'm also using it to heat water.

Can you install the equipment in the garage instead if the attic?

You can, not a problem as long as you can run the cables to where they need to go.

Yes, from March to September, it produced more than I needed, so going into the winter month's I now have about €450 credit which will cover most of my winter bills.

Brilliant Video John and couldn't be more timely. I'm in the process of moving to Ireland and buying a house in Co Kerry. I'm keen to add PV panels and have spent the last week on the SEAI website and numerous PV installers and providers. Have to admit your video taught me more about the system than I learnt online. Want to come and install mine? 🙂 I also didn't realise there was a fireman's switch. In the US PV panels are definitely used as backup in case of power cuts. They isolate their AC from the grid but leave the house standalone. Is that not possible? how does it work if you have your own power generator?

Hi Donal it is possible to separate the house from the grid in the event of power failure, but the regulations state the solar aray must be isolated in the event of power failure. I have no idea why you can't isolate your house and continue to use your solar panels. I can't get a satisfactory answer to this. You also run into problems with a back up generator. If your solar system sends excess power to the generator it will destroy it. It's fine as long as all the power generated is being used, but when you are using the generator you are disconnected from the grid so you need to isolate the solar system from the generator or risk sending the excess power into it.

@@JohnMcGrathManInShed Thanks John. by backup generator I meant how does it work without PV system. If there is a power cut you can use a generator to power your house? does that not send power to the grid too or are they completely switched over to use the generator and you then manually switch back to the grid when power is restored?

@@donalfalvey145 again you can, you can use the second output on the hybrid inverter to power a socket that is separate from everything else so you can use it as a power supply from the batteries in the event of power failure, to power the whole house from the batteries you would need another switch to isolate the house from the grid when the power fails.

Hi, I had some questions different regulations in the UK, but hybrid solar inverter automatic self isolate when the grid fails as it is no longer receiving power from the grid to operate. they normally change over to EPS mode same as when you isolate the unit with the rotary isolator. Are you not able to install a ATS (automatic transfer switch) so that you can supply power back into your house/ some sockets in a power cut while at the same time cutting any power from flowing back down the grid? Over here in the UK to do this we require a dedicated earthing method TT earth rod like when using a generator.
