Do you have the model number of the inverter to hand?

Not sure if its the model number but the name I got was SigenStor EC 5.0SP
Bad month so far, but I did the sums on my returns since I had it installed in March and I'm more than happy. Nov-Jan are always going to be very low anyway.
With generation poor at this time of year, I've set my battery to charge up during the cheap night hours we have on our EV Smart plan, so some of my daily usage is at 7c a unit. I also set it to charge for a couple of hours before the expensive peak rate kicks in between 5pm and 7pm so I never have to buy any units at peak rate (which I think is around 45c a unit)
My total electricity bill for the year is likely to be around €150 (admittedly some of that is down to the govt credits that I would have received either way).

Just a quick follow up. The net cost of my electricity over the last 2 months has been the princely sum of €45, as compared to my previous average of €110 per month.
I wish I had more room, to put up more panels!
For anyone who isn't aware, the actual solar panels, are typically cheap enough, averaging €300 - €400 depending on make and model etc.
In fact, I'm starting to consider building a small extension to the back of our house, and top of my concerns isn't the internal floor space, amount of natural light, but how many more panels I can install, once it's built
Aren't you capped by the size of the inverter?I wish I had more room, to put up more panels!

Not really. If you put up say 10kW of panels with a 5kW inverter, yes in the middle of a summers day the maximum you can generate is 5kW, but outside of that peak time you’ll be generating double what you could have with half the panels. Given that the vast majority of the time you won’t be getting full output from your panels it makes a lot of sense to over-provision them and let the inverter ‘clip’ the power in those few summer hours where you are producing more than it can use.
That's it, exactly, @Zenith63
Sadly, I'm also only talking about another 3-4 panels, as it would be a modest enough extension.
A very interesting link with heaps of useful You tube videos about solar PV has just been removed, presumably because it is (indirectly) associated with a commercial entity.
Could I request the mods to reconsider, bearing in mind that the channel owner is UK based so presumably doesn't sell product in Ireland?
