Solar panels and battery - any real world reccomendations?

Who did your installation, and would you recommend them? I'm just down the road from you based on your profile location.
This is insane value compared to what I paid for mine just a year ago.
I think the difference is going to be very marginal, and there are always flaws in videos on YouTube that claim they work better.

I saw something the other day about battery prices really crashing hard again.
Forget where but it was something like down another 50% vs about a year ago.
Its why over the last year I have moved from "i should protect my batteries for their 10 year warranty life" to "rinse the hell out of them and if they fail then plan to get new asap"
Also I believe from stuff I have read that they are now saying most LFP degradation is coming from age as opposed to usage, so you may as well work them hard up until the warranty point.
I haven't got any idea on Jan yet, but my system is just over 2 years old and as of end of 2024, I had just passed 30% recovery at 30.1%
Its not an exact science modelling that, but its going to be ballpark reasonable.
I would probably be able to buy a system like mine for 30% less now. So you could say I haven't gained anything, but that cannot carry on forever.
And if it does, roll on the next system

Heatalbe are a joke wit their banging on about REA panels, and 380w Micro inverters, and they are forced to install an inverter for the ESS. They are 100% off my recommendation list for people, there are edge cases where it may be better but not £7k better. A Tesla PW3 with more panels will cost less, and be waaaaay better over all.

We used Cahill renewables for the install, They’re based in Kent and Essex.
The sales staff were pretty good and were open to tailoring the system to my needs not just a standard this is what we fit install. The actual installers were great and listened to where I wanted the components put and how I wanted the cables run through the house. After care has let the side down slightly with the office being super slow getting my handover pack out to me.
Overall I would recommend them. Cost wise it was 2k cheaper for the same kit from another installer I was originally going to use (skylar solar).
