It's Energia, I nevre know how to read the bill. It was a cheap rate, after the rate they have a discount amount listed against entire bill.....cant see what the exact rate I do have

Ah right, you are probably OK so. You are just quoting the pre-discount price.

Your real rate is probably around 16c, not 22c.

I know I was with Bord Gais on reduced rate and Energia was a lot cheaper. No idea after that :P:P once contract is up I start to get worried

If it's been a year since the contract you should ring and find out if your cheap rate is over and go to bonkers.ie I usually set a reminder for 1 year later whenever I sign up so I don't end up paying the full price after the year. AFAIK Energia is currently charging 16.16 after VAT for the day rate.

As Unkel said if you do use the immersion at all, go for the iBoost. One last thing I would add is: How big is your tank? As does the immersion heat the entire tank or just the top - sink vs bath.

Good point, my iBoost was diverting to the bath element which did not suit us so a switch of one wire in the unit now sends power to sink element only which is perfect, the electrician did it not me.

It's a shame the user cannot have a switch on the unit to divert to bath element or sink element, these days I'm exploring electricity which isn't what anybody wants and if I could easily switch to bath I would.

This is the actual rate:
Your day rate including vat is- €0.1591
Your night rate including vat is- €0.0763


Tank is big...twice the size of the one I had in old house. It has sink/bath alright


Tank is 104cm high x 40cm side by the looks of it quickly with tape

Yes that's the rate I have. I'd say go for it then.

104cm x 40cm, any idea how many ltrs? 300 ?

That's not a very large tank. More likely to be 120-150l. 104x40 are not standard measures. Heights are usually 30, 36, 42, 48 inches and widths are 15 or 18 inches for copper tanks. If its a joule then the measurements will be different again.

unkel

And no point getting solar thermal or PV unless you have a large cylinder to store the water heated by the sun. Very minimum 300l, but I would aim for 400l or more

Do you mean automatically or are you OK with manual? Most bath/sink immersions have a switch to allow you choose which you want to use, your iBoost can be wired in before that switch, giving you the ability to manually choose the element. Very easily added if you don’t have one.

Had a better look, 18 x 42"


So what 120ltr?

Thats a big f**ker :P expensive i guess

That worked perfectly. My battery charges from solar only now, as I expected. Why the installer set it up to charge from the grid overnight is beyond me.

If your on dual rate it’s cheaper that way for you.

Mine is a slimline 360l, it was the biggest that fitted in my hotpress. It replaced the standard UK / Irish 120l cylinder

Which one did you for?

Shefwedfan

How much overflow would you need to heat a 360l? I would be concered with a big tank you would be jut peeing into the sea so to speak :-)

Back on the trail for solar, now that I've saved up a bit towards it.

Any particular deals etc going nationally? I'm in Donegal. Had a few quotes from locals a while back but got the impression that one was very expensive and one was a bit of a cowboy.

Looking for 4kw I think plus storage. I have scandalous electric bills due to a dryer-happy wife, a 400l tropical fish tank and an electric car. Usually paying about €200-280 bi-monthly depending on the time of year.

Can we name supplier on here?


I know the company I used are having a reduction at the moment, seen on facebook and that how I jumped on the upgrade option at cheap rate.....


You can PM me otherwise, they ended up coming down from North so cover everywhere. You can probably guess who they are.



So far, I think the system is exceptional but no experience of another system so hard to rate. I do think the advice of more panels given on here was the right way. Then again the 19 panels only cover one small cornor of my roof :P I could stick another 100 before the roof would be full.



The dryer is a beast, you need a clear days and lots of panels to feed it. But if you are taking a huge chuck out of it then it will reduce bills. Our dryer, no idea but maybe as it is older it is not very efficient but it eats power.

I'm not jealous of the size of your house at all. You bastard :pac:

Mine was made by Joule. An Irish company. Have only heard good things about them.

Old pic of house but you get idea. The red is the space used up for the 19 panels.



Now I guess to put more on I need to put in another invertor but won't be doing anytime soon unless FiT made it a good option

unkel

Size of that :eek:

Max the ESB will allow you to connect to the grid is 6kW. Unless you upgrade to a 3 phase connection I think

Don't think you will see much benefits.
I have multiple fish tanks. During summer they do not use much electricity as heater does not come on and even if it does it is during night time.
As for dryer again during summer we fry the clothes in the back garden
To get most of it you need to change the way you use electricity.

That sounds a bit extreme :eek:

Agree with your post though. Electric heating (fish tank) and charging a car can be done at night at the 8c rate. With a 4kwp system and a decent battery, he should be able to cover his baseload pretty much 24/7 in summer though, so that's a significant enough saving in its own right

I'm confused... His post says there is essentially no point in solar as I won't see much benefit.

You say you agree with his post, but also say that I'll see a significant saving in the summer?

Also the heater runs pretty constantly in my tank, not just at night. The tank water temp is 25 degrees. The house is usually around 22.

Few other 24/7 things like CCTV, 2 freezers and the fish tank pump. Car only ever charges at night and we try to confine dryer and dishwasher to overnight, with the odd exception.

PS she won't dry clothes outside. She is severely arachnophobic and spiders do love snuggling up in clothes on the line!

Of course you will see a benefit. Question is how much. Any monitoring of your usage? do you know when you peaks are? what are the peaks? will they be during your "good" hours?



How do you cook? use a slow cooker much etc?

Don't use a slow cooker. Oven is electric, hob is gas.

I don't have any monitoring at the minute.

It is, but there is nothing stopping you connecting more than 6kW of panels to inverters with a maximum output capacity of 6kW.

Solis Ginlong inverters have a CT option for export limiting which could be useful if you wanted to go really big. This would allow you to have a greater than 6kW Solar AC output capacity and output would only be clipped if export exceeded 6kW.
Hard to see any motivation for it without a FIT though.

You do not need to run tropical tanks at 25 degrees unless you keep discus. During last 2 summers I had to actually chill mine to keep them below 25.
Fish tank pump and other base load CCTV, fridge etc are small to make difference. The biggest users are the ones that need to produce heat(driers, ovens, dishwashers etc).

During summer most of the energy will go to grid, unless you have someone at home constantly using it, have big battery or charge your car during sunny periods.

I am not saying that you will see no savings. You will but to get the most of it you will need to adjust your usage.

I bought an owl ....cheap and cheerful but it tracks your power. What your base load is etc. When you use power and when you dont...


It was handy becaue I knew then what I needed and what was my big power itesm

I know, that's why I said 6kW and not 6kwp

Although I guess the subtlety of that would likely not be appreciated by someone less knowledgeable in this field than you are

Didn't know about those inverters that capped the export. Might be handy for some people. Do you know what the max export is for a domestic 3 phase connection, just out of interest?
