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

Lithium Iron Phosphate batteries don't burn. So you can rest easy on that count.

Well first up, that's not a bad quote at all what you have.

Personally I'd always go with a battery for storing the energy over a Eddi/hot water diverter. The simple logic is, is that while you can use the energy put into an immersion tank to have a hot shower, that's -ALL- you can do with that energy store. A battery on the other hand can be used to watch TV, or do the ironing......or manually turn on the immersion and heat the same water albeit with a small energy loss.

The payback math isn't there for an EDDI - that said, I bought one myself, but there are other reasons to get one than sheer payback.

If you go for a battery, you'll have to get a hybrid inverter which you probably haven't been quoted, so if you ditch the hot water diverter and go for a small battery 2.4kwhr or such, you'll probably add a €1000 to the quote. Roughly.

Aside : Can you sneak on a few more panels? 3Kwp is on the low side for your average house. 4Kwp is sort of the min I'd encourage people to get. Even more if they can. Nobody, and i mean NOBODY ever complains about too many panels - but I do appreciate that extra panels = more money.

Let's be 100% clear - you do NOT need a Hybrid Inverter to support a battery. In fact, I believe that it is more advantageous to have a separate Storage Inverter (to operate like a Tesla Powerwall). A good option is the Sofar ME3000.

So @Treppen could get a SaaS system for €3600, and then add a Storage Inverter and batteries later - which can also be installed in a totally separate location too.

As we know, the ME3000 works perfectly well with Pylontechs. We know the Pylontechs are a decent solution since they are modular. I cannot see why installers would not be offering them.

I do think that it's more likely that people will only have heard of Tesla Powerwall a, and would get frightened off by their cost, and would not be aware that there is another similar alternative.

Energia night rate 6.94 inc vat

Just to let yous know 👍

Night meter is what I'm on..not sure about smart meter sorry

Smart meters are not enabled for Night rate at the moment.

My Energia EV plan night rate is 5.9c/ unit. (Incl.vat)

Daft question but can you get the EV plan without having a EV.

I've got a quote for materials only

Double row system

6.2 kw of Longi panels

5kw plyontech battery

6kw solis hybred inverter

8229 Inc VAT

+ Installation and sign-off less grant it should come in at 7k

And I have an email but I can't say from where that says you will get 1c a kwh... see how that works??

The amount we will be paid will be set by the individual retail companies as far as I understand. And there's no way on gods green earth we will get more than the wholesale price or even close to it. Smart money says 5-6c a kwh at best.

Be wary that you are being told a line to get you sign on the line...

Is a smart meter needed for exporting power when the utilities have to pay for it ?

7k supply and fit. 8229 for materials and about 1800 for fitting less the grant leaves 7k ish

Hi all,

I would really appreciate your thoughts/insights on what specification of PV Solar system I should consider based on the following data:

Information:

·        Have a Day/night rate tariff.

·        14.5 kW heat pump

·        Have solar thermal which provides all our hot water from March to October

·        EV ordered and due in April – (current daily driving distance between 120 and 180km/day all year – school runs and kids sports taxi service. Car at home from 10am to 3pm most days

·        Both working from home and that is not going to change.

·        2020 – Consumed 19829 kWh – split circa 65% Day / 35% Night  

·        2021 Consumed 15882 kWh – split circa 60% day / 40% night

I have 2 south facing roofs that can accommodate about 22 or so panels in total and 2 east facing roofs that can accommodate 14 and 6 panels respectively.

Unable to do a DIY install except maybe an additional battery and have a finite budget but “Go big or go home” is what I want to achieve.

If this was your situation what would you look for in your specification for a quote after the following:

1.      6kW Inverter

2.      No eddi Diverter

3.      EV charger

4.      5KWh or 10KWh battery storage?

5.      What size of array I am thinking 7/7.5– would you face them all south or look at a combo of south facing and east facing strings?

6.      Anything else to consider

Thanks

Yeah - but bear in mind they have no oil bills! I'm still trying to work it out myself. I put in about 1500ltrs of oil a year for a 3500sqft house, I'm trying to work out if I put in air source will my bills still be the same etc..
