Ta, missed that so pretty much same as 8.2
Solar panels and battery - any real world reccomendations?
- Thread starter GinG
- Start date
I'm tried a couple so far but it's like no one can be arsed to come back to me, although can imagine they're getting lots of queries
Yeah they all are. I've sent out quite a few emails and received two responses.
I think it helps to be specific. KNow what kind of system you'd like, what you want quoted for. Shows you've done homework and are serious.
Finally found a quote/system I think I am going to go for, it is £13.3k though, slightly more then I wanted to spend. But I guess at least it fits what I am after nicely with a 5kw discharge rate, and future proofs the setup.
6.4kw solar setup (16x400w jinko panels)
Huawei 5kw hybrid inverter
3 x 5kw luna huawei batteries
backup box for powercuts
secondary small fusebox

It takes some researching until you're happy with what you want and part with your hard earned money.
I've a similar budget 14k, and a Givenergy spec I've posted further back in this thread.
How are Huawei perceived in general? Good kit?
I prefer GivEnergy just as it's where I focused my research so far, however one GivEnergy reseller has just recommended Huawei simply given that Huawei are all solf out of the 8.2kW and the replacement 9.5kW nowhere in sight atm

Seen as good to very good, but also seen as being quite highly priced vs. the others on offer, however the gap seems to be narrowing, due to prices going up. My first quote ages ago was with Huawei kit and it would have been to get a Powerwall 2.
Yes, seems to be well recommended from what I have researched. The battery tech seems very impressive as well, compared to give energy etc. Seems a better product (higher discharge rate etc) with a decent battery management system allowing better balancing and longer lasting batteries due to the parallel setup. Fingers crossed if I ever add more batteries years down the line, it works as intended!

Ok, quote number one - welcome thoughts/tips etc! Keen to maximise generation - this should pay back in under ten years (based on previous electricity rates, let alone current madness!)

Bloody hell, such high installation costs. I assume this is a single days job by 2-3 people??
If you compare to one I've just ordered, same 7.2kW solar but two gen2 3.6kW inverters and two 9.5kW givenergy batteries , solar with optimisers 14k

When I had my 4kw system installed I think they managed it in a day, two installers and an electrician IIRC, but it was a long day - it was getting dark when the panels were all finally fitted, but it was December. Really can't remember if they came back the following day - too long ago.
I'm hoping I can go the DIY route for battery and additional solar, and just hire an electrician for the electrical work, I'm more than capable of installing it.

If buying a battery after the panels, someone said buy a single panel with the battery to 0% VAT it, unless the new 0% VAT thing also 0% VATs the battery.
The cost of the panel should be less than the 20% VAT you save.

We have a double garage with flat roof, so I'm hoping to put some panels on there. There is physically room for 12 panels (with spacing to prevent shading), but you have to allow a certain gap to the edge, and they can't be ballasted as that further increases the gap, so will need fixings through the roofing felt.
If I can get the 12 panels on there, that will give us 8kw of solar including our existing system, which will hopefully be enough for one or even two 9.5Kw batteries.

I'm having the panels on a flat roof, but having them east/ west arrangement to maximize roof area, longest dimensions of roof is perpendicular to south. Yes, not as efficient but the extra panels make up for it.

@94JDH are they going to be installed using ballast, or through fixings? What spacing have they specified at the edges of the roof? Is that a single storey or more?
Mine could be installed square to the garage, and all would face SSW, about 220 degrees on a compass on my phone. Same direction as one set on my roof, which performs slightly better than the other set which are facing SE.

It should be 600mm along the longest edge, around 1m on the shortest edge, it will be rails with ballast blocks.
I won't have fixings, as both flat roof areas are EPDM rubber - single storey garage roof and garden Room.

Thanks useful!
What is the benefit of two inverters out of interest? O believe the 9.5kw batteries aren't available until late summer apparently, guy did mention those.
For myself, the benefit is charge/discharge at 3.6kWh per inverter/battery which means if needed I can supply the house with max 7.2kWh compared to 3.6kWh on one inverter.
For reference the old batteries 8.2kW charge/discharge at max 2.5kWh. In addition, having two inverters means I can also charge the batteries fully in the 4 hour off peak window in winter if needed.
Half of the 7.2kW solar will be linked to each inverter for maximising usage.
