Installers have agreed to take down panels for free if council decided in favor of a complainant and wouldn’t give me retention permission- I can put them up in another spot if needs be. I have East west split so will prob put six panels on front of house (east) and eight on back (west). My installer appears very confident planning law will change to allow bigger systems soon tho.

Realistically I don’t want to go down the route of planning as additional cost for drawings etc. so thought that I would go with the 7 panel at approx. 300kwh each would give me 2100kwh, south facing system. There is room to add additional to the garden rear 3-4 panels, but as splitting and what I have read about additional invertors/diverters? Not sure this is worth the cost for another 1000kwh Basic yearly consumption 5700kwh, on a bad day using approx. 18 units (@€;0.1450). My question is realistically is a 2k system going to really make any drastic saving when considering payback time and my usage. I know that the main issue is the washing machine/tumble dryer running 2/3 times during the day and 4 girls’ hairdryers daily plus ever other device they have charging and 2 TV’s running daily. These are items at the moment I have no say in, when they all move out may be. Any thoughts would be great or suggestions solar sales seem to justify 2k but think this is a hard sell, would be great to be more self-sufficient but would realistically need to justify the investment for the savings I calculate. Maybe it’s not the time to jump in but the grant makes it a little more attractive. Thanks

With wireless you always have the potential for interference as has been detailed on this thread already. imo, a wired connection will always be better and more reliable than a wireless connection but it is, of course, dependent on your specific circumstances as to whether that cable can be run without digging half your site! Im sure Harvi works fine for people but if its possible to go wired I would do that.

Also,some of you highly recommend some specific branded EV chargers that does wonders too (aka for sales people bonuses). Can anyone of you show historical and / or live how a PV system behaves with a battery and / or EV car !?? I will really really love to see some reports,some graphs,some returns of the systems in usage... How the system performed "today" with that base load on monday and, over the weekend? How does the system balances my life,my usage,my appliances while taking care of the batteries... How does my PV and charger charges the EV car day time and on the night time . So far,i just seen sales people making assumptions,throing up quotations and opinions based on best return for end user (aka,my arse,for the installer and / or seling company). I love to see graphs and reports... how does the PVs performs with a battery attached ?! Asked few guys already and being told to shut up, 'case that charges does wonders as he has it installed.No graphs presented,just keyboards and mouse.And sales numbers... I guess, by now the number of systems installed by users here on boards is big enough ,is mature... We can afford to see some reports,isnt ? Most of the users asked " can you PM me that installer as the price seems right for my budget/grant" !!! BUT NO ONE asked...how does the system performes, how does the battery gets its 100% quoted installed capacity, can i read your dashboard, can i see some bills ,some real fcukign savings !?? No,all about price of the installer to match the grant ! HOW DO I KNOW THE SYSTEM WORKS !?? just by green light on and off ? Thanks in advance guys,no offence intended.

Last weeks low consumption wasn’t typical. Now I’m wondering is my high usage making PV more attractive again. Is there any case, or any cost at which a battery becomes sensible? It’s overcast here in Donegal,today so I wonder would I have got 12 units produced from the PV in any case?
Rodstar028 wrote: » Wondering if any of ye have noticed on your systems on days of power surges to the panels are the inverters inclined to leak some of the power to the grid instead of adjusting to send power to batteries. Then also when night meter is installed are there settings that require changing and in your experience what are the best ie can you charge batteries by 2kw only etc

unkel wrote: » If you are unhappy to go for a system with a payback time of 15-20 years, AidenL, you could consider going for a DIY install of PV only, no battery. Just have an electrician hook it up to your consumer unit. If you buy the parts well your payback time should be under 10 years
wexfordman2 wrote: » That equates to about 20 euro per week in kWh, so 80 a month, plus standing charges if approx 20, give you monthly bill of 100, but bearing in mind your usage this time of year is decreasing. Payback is something you just have to feel.co portable with or not, and how much it is, depends in hiw much effort you put in to maximising your solar or not. To me, the question was a but easier to answer, I had the funds, and it was losing money sitting in a bank instead of working for me. If you have to borrow to.fund it, it's a very different question though, but if not, maybe thi k about it that way. How hard is the money working for you sitting I some.crappy low interest bank account. Edit: you asked whether it made it .ore or less sensible...well, lower usage is always a good thing, but it probably also makes it easier.to balance your system and maximise usage.
