Domestic Solar PV Quotes 2022 - No PM requests - See Mod note post #1

There is precisely 0 chance that human ingenuity will beat a 10 year return. If they solved fusion tomorrow, it will be 20 years before sufficient plants are built to meet current demand, never mind future. If the government said tomorrow they are going to cover the midlands with solar, would be 10 years before a sod is turned.

Quote:

3.28wk system

8 panels x Jinko 410w Tiger All Black N-Type

Solis Hybrid Inverter x1 c/w Home Energy monitoring App

Marlec Solar iboost

7k after grant

BER included

Thoughts?

Would it be too small 3.28wk to even bother fitting panels?

That's as many panels as I can fit in my roof unfortunately.

In reality, charging your car from solar only saves 10c or so per kW, since you can charge the car on night rate.

So I wouldn't install extra panels for car charging, I don't believe it stacks up financially.

Thats not bad.

At the risk for speaking for Maulbrook, the "no" above is in relation to the price. That price for 3.28Kwp is......excessive. Should be no more than €5k (max) after grant also 3.28Kwp in panels can be worthwhile. A lot of it is down to what your consumption is.

Also I'd be interested in knowing why you think that 8 panels is all you can fit. Obviously I've not seen your house, but don't rely on the comments/thoughts of 1x installer. Have you measured the roof? Do you have multiple aspects (east facing/west facing) etc. do you have a shed/garage. It could well be that 8 panels *is* all you can fit, but at the same time.....that comment maybe something that "suited" that specific installer if the number came from them, so take it with a pinch of salt if it came from a supplier.

Im in this process at the moment. Heat pump and install (usually two different companies) for me is coming in around 11k. Underfloor heating is seperate.

The heat pump may be eligable for a grant, mine is semi-d so i SHOULD get back 6500. In order to qualify for grant, youve to get an assessment to see what you need to do basically to make your house suitable for the heat pump. Once works are complete, assessors come back out and do some more tests and make sure your heat loss indicator is 2 or under. If it is, you will qualify for the grant rebate. If you dont get 2 or under, ive no idea if you can go again and get assessed, but then if you complete works that the assessor has suggested I dont see why you would not if you get me.

So the assessment is costing me i think its about 800 all in, i get 200 back from the seai also, so really the grant is worth to me under 6k if you get me.

That setup borders on being pointless and over 6k

I also have two questions

1. Eddi - why is it required if you are heating from immersion which would be taking power from solar if installed

2. Battery capacity - one provider said smaller battery is better for more life as in ireland, we may not be using all cells all the time in the cycles and reduce the battery life. What you think

Thanks

1. The Eddi is what tells the Immersion to turn on/off based on how much excess you are generating/exporting

I am getting mad prices even from those installers named in this forum.

I dont know whether or not the increases are justified but I am being put off fitting panels at those prices which I have been getting.

Defending on the brand of heatpump you may be able to use the excess solar to turn the HP on and off. So more efficient than an Eddi but people who have done this seem to have mixed results with how well it works

Hi.

2 person household. Currently use c. 2500kwh per year but consider also putting in a heat pump, hence looked for two options

quote

5 x Hyundai 400w

eddi

ber

6000euros

as above but 10 Hyundai 400w panels. 8000 euros

5kw battery would be 5000 euro additional.

This is the first quote I’ve gotten. Is it a bit high? Any ideas of what would be realistic please?

That...... could be a new record there.....as in the most over priced system quote we've seen. Congrads, your a winner :-)

With 2500Kwhr a year, you'd probably be well suited with a 4.0Kwp system with a small 2.5kwhr battery. Should be about ~€6-7K (after grant)

I would however future proof yourself and go for something a little bigger. You'll probably have an EV like everyone when the government ban internal combustion engines in 2030 (I know it's a few years off, but you might have one sooner?) and go for a 5.0Kwp system with 5Kwhr battery. Ballpark €8-9K after grant.

But yeah, the 4.0Kwp and small battery would see you right currently if your using 2500Kwhr.

Aside: You sure it's only 2500kwh, average household in Ireland is about 4200Kwh?
