are you limited to 6 or 8 panels. Would the roof take more ?

the price is very high

@ted1 @con747

Can you explain that a little more to me.....I just want to understand the logic behind it. I was adamantly told by the 1 provider who did the site survey that the NW was not worth it.

a Separate String will mean that it wont affect the output form the rest of the system.

panels are about €55 wholesale. you are paying for an electrician, roofer , BER and inverter. adding a few extra panels won't add to much to the cost. maybe 1/2 to an hour for the roofer, that's it. instead of 3 year pay back it might be 5. but certainly worth it.

a 3.2kw system with a 5kw battery should be closer to 5-6k.

ignore your usage, go as big as your roof can take.

is that 11,500 before of after the Grant?

****** seem to be advertising the best packages give them a call. I’ve no connection with them.

Hey guys

Just a slight update and thanks to both for the information about the NW panels and seperate string. Spoke to one particular company who "sat with me" and went through the whole thing and the logic and they were in agreement that while the NW won't do much for me...at the cost of panels it will do enough to offset any use if the battery during peek times and help save on the battery use to feedback to the grid. So with an additional 8ish panels on the NW facing its a no brainer for where I am.

They are going to do an additional survey and come back to me with a quote but initially not only the quote but the companies attitude to helping me understand my situation probably has me going with them....I'll update here when I get the quote.

..and I thought network engineering was complicated at times :P Thanks @graememk I had seen the site and was trying to figure it out but between 60 - 70% was where one of the installers had mentioned, so its worth it to put the panels up, but to make sure they are on a separate string acording to other boardsies and the isntaller

I actually have a quote for a similar set up (albeit a smaller battery):

24 x 475 Watt Panels (AIKO-A475-MCE54Db)

1 x SigenStor BAT 10.0

1 x SigenStor EC 5.0SP

1 x Sigenergy HomeMax SP Gateway

€12,700 (after SEAI grant).

I am thinking of increasing the battery capacity by adding 1 x SigenStor BAT 6.0 to that setup, but that depends on how much they'll charge me for it.

They just got back saying they can add the 6.0 battery for €2,100.

Hi all, just doing.ky solar panel review and got a first quote yesterday. I was slightly underwhelmed on the level of review, calculation etc by the rep as I understood the most important thing was analysising usage etc.

I was pushed towards the below with the note that it is very smart with ai etc. Im not overly.cpncerned re ai and the modules themselves will be attic installed so the look isent important. Are there other similar spec inverters/ batteries that can learn habits and automatically decide best time to buy, sell, etc.

Its strange to see a quote without a BER. I thought that if you wanted the Grant a BER report had to be done?
However, its not so expensive so you could get it yourself. Those quote seem on par with what I was being offered for similar.
