Domestic Solar PV Quotes 2026 - No PM requests - See Mod note post #1

Personally I'd ask them for an alternative hybrid inverter. Nothing wrong with Huawei, they are seen as a premium brand. However if you ever decide to add a battery down the line it'll have to be Huawei as their inverters are locked to their batteries, please note they are expensive as the price at the bottom of the quote for the 5kWh version illustrates.

For context, I'm looking at adding a 16kWh non-Huawei battery which can be bought online for between €1500 delivered. Throw in a couple hundred Euro if necessary for a local sparky to connect.

Other than that it's a competitive quote. You should save a few hundred Euro by asking them to swap the inverter for a Solis for example.

Just off the phone with an installer. Awaiting the official quote via email.

Got the Sigenergy hard sell and told all about its AI capabilities.

12 panel system with a Sig inverter and Sig 6kW battery.

€9200 after grant.

Come off the stage lads.

I was told by one company they can’t install a changeover switch due to the wiring requirements, inverter compatibility and paperwork.

It’s a Livoltek inverter and battery system they were supplying.

Anyone able to add anything to this statement by the installer?

Installers can definitely do a change over switch on some systems anyways. You might have to just try get more qoutes and put this as one of your questions to ask.

How long is a piece of string unfortunately. Depends on the battery size and your power usage. My house with nothing major on uses about 300W on average. so a 10kWh battery would in theory last just over a day. Your usage might be less than mine though. Also I could probably cut out a couple of things to try get that figure down.

Here’s both my official quotes. A bit steep I think:

Solar newbie. Looking for advice about power outages. I'm concerned that the war in the Gulf will become prolonged and we could be looking at no power. I was interested in a Sigenergy battery due to the IP66 (outside mount). But was quoted €3k for a switch. Researching the Internet I came across islanding as a solution run out of the inverter. Does anyone know anything about this? Is it popular and which inverters would have it? Even a redirect to another site would be great.

This is what I got this morning, seems high for the basic inverter with a small battery.

1. I worked out that each panel my front roof which is North north west would generate roughly €42 a year at current export rates. Your price per panel sounds too low though, most quotes I got were €200+, with one or two being €175. But even if it is more expensive, they would pay for themselves in 5 years in theory, and should last 25 years.
2. Depending on the charger they are installing that is about the price it is. I paid that for a zappi install 2 years ago. It doesn't appear your getting any discounts for them being their anyways with that quote, so maybe worth shopping around.

4. Doesn't seem expensive to me. One big advantage of batteries is it allows you to offset more expensive daytime electricity of EV rates, especially during the winter when solar generstion will be low. so you'd have to check how much batteries you'd need to cover your usage if you wanted to go down this route. Get your smart meter data from ESB Networks and put it into killowat.ie and configure different hypothetical solar and battery systems to see what impact it would have on your yearly bill.
5. Just parroting what I've seen others say but I think most people are happy with them. I upgraded to the Solis s6 for €200 because it has a generator port. (I'm waiting for my system to be installed)1

IMHO,you won’t regret that 2nd battery and that is a good price for that amount of equipment

Also get an Eddi for the hot water and invest in a couple of pumps for showers instead of electric showers heating the water all the time in the showers
less drain on the batteries

Obviously get a few like for like quotes

Teenage boys and their insatiable need to shower and smell nice for their girlfriends would be one reason

With your system the 2nd battery would really come into its own in the winter time October to early March as the days get short and on wet dull days

There’s no really right or really wrong answer

If you want to save money,you could put in the extra battery later

You are restricted to 6kw in daytime export but you can also export excess power from the batteries at night time during the summer

you have an extra 5 or 6hours that you can export your excess to the likes of pinergy for 25c kWh

So it turns out that I have an old Siemens meter and not a smart meter. I have decided to go for 8+8 jinku panels 455w, a Goodwe inverter GW5000 ES 20, two shunts, net cost €6100. Probably a little expensive but company is long standing and highly rated.
