There was an additional grant for a battery but discontinued last year.
Was not referring to them, no idea who you’re even referring to, I was just making a general point.The Enniskillen crowd are not cowboys. They have probably installed 100's of units this year.
I have a SoFar 5kW inverter, the spec sheet says <5W standby losses. Looking at the data from the device it’s currently (dark, no battery charging/discharging) using 9W.I tradesman (not involved with solar PV) recently told me that the controllers etc for a domestic solar PV system can consume up to 100w on a 24/7 basis. If this assertion and my calculation are correct, it would consume up to 875 KWh per annum (100 x 24 x 365 / 1000), thus making a serious dent in potential savings and elongating payback periods. I assume that the system itself would consume some electricity but I had no idea that the consumption could be this high. This could, of course, be completely false.
Can anyone shed any light on this?
The inverter size is what matters because even if you connected 20kW of panels to a 5kW inverter, the maximum power you could send to the grid would be 5kW.Still considering this and was told yesterday that ESB has a limit on the capacity of PV panels you can install, approx 7. something kW. Does anyone know if this is true? One of my quotes is for 8.8kw. (21 panels).
Thank you. Nothing is Huawei. I suppose, as we don't live near any large urban area, competition is limited. It does look like there's a fair chunk in the quote for fitting and labour. I would also feel that back up and support would be better from a local firm.@Slim
Panels typically run at about €300 per unit, possibly a little more for higher end.
The likes of a Dyness 5.1kw battery is about €2k.
You'll get a 5kw Solis Hybrid Inverter for about €1500, I think the 6kw is about €300 more.
Add some extra labour, fittings etc and some additional profit margin, and your quotes still look high.
Is it Huawei equipment, by any chance? Their equipment is good, but notably more expensive.
You might like to also keep an eye on this discussion thread, given some related info.
You can pick up Longi 440W panels from Solarticity for ~€95 ex vat/ex worksPanels typically run at about €300 per unit, possibly a little more for higher end.
I got a 10kw battery with my system and never regretted it . I have a day/night smart meter and charge the solar battery on the cheap rate at night time. Therefore I am getting my daytime electricity ( most of the time!) from my solar panels and/or the solar battery. I get paid for anything that goes back to the grid at a better rate than I pay for the night rate.Thank you. Nothing is Huawei.

The significant question, for me, is battery or no battery. Even at the higher price, a modest return will exceed anything we'd get on the money in the bank or credit union.
This is a key point, what would the FIT rate be versus the night rate? I'm struggling to get a clear picture of what rates will be available from, say, 1st April. Also, my quote seems expensive, especially for the battery.I get paid for anything that goes back to the grid at a better rate than I pay for the night rate
Interesting but who would fit them etc?You can pick up Longi 440W panels from Solarticity for ~€95 ex vat/ex works

Have you signed up for that PV Solar Facebook group that I recommended a few weeks ago? If not then I urge you to do it.
Then, upload your quotes there and ask for views. Also ask there for tips on any local installers.
There's also an active ongoing debate about whether or not to install batteries. I did - and I'm glad that I did because for me, the cheap night rate electricity made it a very attractive add-on.
https://www.boards.ie/categories/renewable-energiesThanks all for the replies. I have, so far, resisted the pressure to join FB but this, and other areas of interest, are persuading me to take the plunge.
