Solar panels and battery - any real world reccomendations?

Just wondering what your actual daily electricity costs incl. standard charge are? (for those with battery)

Basically the standing charge for me, normally use about 0.5 kWh and if we shower instead of using bath about 2kWh

In winter time though I am charging at cheap rate over night (if I check weather and alter the settings)

I don't have stats yet for a lot of time, only last month so far, and partially mine a bit cheaper because of Go. I hope to match similar this month.

Just over £1/day including SC and VAT. This is 01/09 - 26/09.

Most of my peak usage is just overage on consumption with high use equipment. Stuff like ovens will go above the 2.6kw my battery can provide (plus my regular home usage is 400w~) so I will always use some electric even if the battery is fully charged if I use certain things.

Since 27/09 - 20/10 I have drawn 170.84 kwh from the grid according to my inverter stats. This is 24 days so far so a little more consumption per day than the previous month, but most of it's off-peak again, and generation is lower in October.

That usage is impressive, my bill for 29 days was £105 all in, which has reduced quite dramatically since getting a battery. I thought my bill was quite reasonable before seeing yours.
 
Usually I'd be burning about 16 kwh per day, for the same time period 416 kwh * £0.34 = £141.44 + £10.67 SC, so a little over £150 before I got solar and battery.

I don't expect to continue this pattern in December/Jan but October I think I'll have a negative bill for utils (both gas and electric) thanks to the free £66 from Gov.

Finally, after 3 months to the day downtime, new correct Fronius inverter fitted.
Back up and running again.

Last Fronius inverted lasted 9 years and 4 months, something to price in when you're doing calculations for repayment time on a system.

Plus, the Sun is out today :p
 
Had a few problems with the dongle and my wifi at home - but despite the grey-ish day today the advantages of having a lot of panels has its benefits.




I think with the scrapping of the price cap next year the ROI will increase so I think despite prices being high it's a good time to invest in solar and battery IMO.

The dongle doesn't like 5Ghz, if you're like me I've had to disable 5Ghz and set it up on a different access point instead.

Givenergy connects to a 2.4Ghz only access point, everything else connects to a different 5Ghz only access point.

Pain :D

It's a right pain - although they state that it CAN do 5GHz - but it blatantly doesn't! :D

What I've done is connected an old AP, on a different VLAN to isolate it from the network, and used 2.4ghz... Ideally I'd like to wire it up to ethernet.... I wonder if a module exists for that?

Have you asked for a price without the batteries but with the same inverter?

I say this as the batteries are only £1900+ VAT each to buy, and it might save you several thousands of pounds if you buy them and have them installed after.

Looks like each battery is 2250 inc VAT so that ties in about right....
 
Just had a nice chat with another company, quote is £15k for 18x410w Trina panels (mono), 9x tigo optimisers for the bottom string, a 6kw solis inverter and 2x 5kwh Puredrive II batteries, scaffolding costs included. All parts in stock and ready to go.

That seems the best quote I've had so far and the guy on the phone was great. Do we think that's probably about as good as it's going to get in the current climate?

Sounds pretty good in current climate that
 
Not terrible at all, that's a big array at least.

I think it's hard to find really keen pricing at the moment.

Optimisers do add some cost as well, but if you need them, you need them.

Make sure it's a hybrid inverter if you can, that will be worth having later on if you add an EV, already part of the puzzle done then :)

With such a large array you may find a 3rd battery useful, balance the generation across days a little easier, and give you somewhere to store all that power.

Hello all. Could I ask for your thoughts please on this quote I received.

18 x JA 380
Lux Power hybrid inverter 3600
4 x Green Energy batteries 3.2 KWh
EMLITE ECA2 (no idea what this is)
10 x CLENERGY ER-R PRO4200 4.2 MTR RAIL (Again, don't know what this is)
£14,152

Now the two things I am struggling to understand:
9 panels will be in the southeast roof, the other 9 will be in the Northwest roof
Also, no G99 needed, only G98 "as it is a G98 inverter"

I somehow do not think this is the best way to spend 14K
 
the last part is the mounting kit. The inverter is small enough that they do not need to apply using G99 (less paperwork for them). I cant say exactly about your setup as people that visit site should be able to quote from being there, but if your using batteries why not get the best wattage panels all on the SE roof?
