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

Go back to the crowd for the 3rd quote and see how much 2 extra panels are. If you can fit 18 of the others, you'll definitely fit at least 17 of the 430w ones, if not 18 as well. Allow €300 for the BER and your pretty much comparing like for like over the quotes.

Im not an expert and am just contemplating getting solar myself. From what iv read on this forum i would not go with a Huawei inverter becuase it restricts you to a huawei only battery should you decide to add a battery in the future. I think huawei batteries are pricey.

Even if you dont plan on adding a battery now, economics and FIT may change. Actually common sense suggests once they have enough people feeding to the grid they will likely reduce the FIT considerably. Its enticing now but who knows in the future. Also good to get the hyrbid inveter to keep options open. Someone may correct me here if im wrong.

Hi folks quick inverter question as I'm comparing two proposal quotes.

How does the Solis S5-EH1P 5Kw compare with the Solaredge HD Wave 5kw?

From what I've read the Solaredge seems the more premium product but just looking for opinions on if the Solis Inverter is any way comparable?

The battery is an interesting one. Depends a little on if you are on a smart meter & if you are on a Day/Night meter. If your not on a smart meter and you are on D/N, then I think it makes great sense to get a 5kwhr battery or bigger if you can afford it. The reason being is that (for now - and this will change) you will get "deemed export" until your forced over to a smart meter. This means you get paid the same if you export nothing and put everything into your battery, as opposed to exporting everything. You get paid the same in either scenario. So for now, makes sense to capture that energy into the battery (and still get paid for it)

The diverter is also another interesting one. I have one, and I'd buy one again - but I should call out that with cheap rate night time electricity it's actually cheaper NOT to have a diverter and export the electricity you have surplus during the day. i.e. you would never make back the investment of the diverter. Again though, even though I know it doesn't "save" me money, I like the convience of 7-8 months a year having constant hot water and I don't have to think about it.

Of the three qoutes, #1 and#2 are much to a muchness. Maybe #2 is slightly better value wise, but also if i had to pick, I'd go #2 becuase it's got more panels. When we have EV's in the driveway we'll all want as many panels as we can.

Lads any thoughts on above?

Are you not removing the optimisers from quote 1? I don’t think they are needed.

Quote 2 without the eddi is good. Will come in at about 9000.

You can buy the 5kWh battery yourself for 3880 (that is including VAT) so you can save yourself 1000 euro on the battery if you think you can install it yourself.

Tell them your holding onto a percentage of the final bill until all paperwork is finalised, I don't see why they would have an issue with that.

Yes, I will be removing the optimisers from Quote 1 (so now €8600). The BER for Quote 3 is an additional €250 for the BER plus €600 for the extra panels (so now c. €9235).

Quote 1 now wins on price but I'm still a little hesitant/nervous about the Huawei inverter.

I have a huawei 6kw inverter and 10kWh battery. I did a DIY install and I could have picked any inverter / battery combo I wanted and I went with the huawei combo over the others due to its features.

I know you’re locked into getting a huawei battery in the future if you do decide to get one; but know that if you do you will be getting a quality battery.

If this is really a deal breaker for you tell the first company your concerns and ask them to use a Solax / Sunsync / etc… it might atcually make the quote a tiny bit more expensive; as the huawei inverters are very competitively priced; it’s the battery’s that demand a premium.

Good luck with the install!!

Drop the eddi that will save you 700. Just be happy with the .21 cent you will get for anything you export. You can have an eddi installed later if things change.

Do you know why they added the optimisers? It’s unlikely that 2 optimisers will make any difference; if a panel is significantly shaded it will remove itself from the string using its internal bypass. It’s likely they could be removed.

Ask for the quote with no battery’s to try and figure out how much they are charging for them. And post back.

I did get quoted for both with with out the battery, the difference is €1,908. There are two panels that will be shaded early morning, I guess that's why the optimisers are included. I did specicically ask for the Eddi as the end goal is to remove the electric shower, but agreed we don't need it right now and could possibly be removed.

Wow. So he’s only charging you 1908 for a 10kWh battery. So he doesn’t want you to know the price breakdown.

so if you take the 12354 minus the 1908 for the battery and also take off 650 for the eddi. Means you’re paying 9796 for 5.2kwp of solar. It’s way too much.

but the 1908 for the battery is clearly under market value for even the raw materials; so the total quote of 12354-650 for the Eddi gives 11704 for 5.2 kWp of solar and a 10kWh battery which is not outrageous. I’d say get a few more quotes.

Hello there,

Can I ask for a bit of advice. The quotes I listed above had an additional cost for a battery, ranging from €2,000 to €4,800. Are Solar PV sytems installed battery ready? Can a battery be fitted at a later stage and if so, is it costly installation or a simple plug in job? Sorry if that seems a bit of a thick question.......

Hi there,

One quote is for a 5kWh (€4,800) and another for a 3kWh battery, €1,950 plus an additional one at €1,750. The general consensus seems to be get them as part of the original installation. Thanks for your help.
