I’ve had a solar installation for five years, I would go with the biggest battery you can afford, we unfortunately started with a 2.4 kWh battery then a year or two later upgraded to a 4.8 kWh moixa battery and I wish I’d gone for a 9 or 10 plus kWh but couldn’t afford it at the time. I’m now looking to add another 9.5kwh battery to take me to around 14kwh total. If I had an unlimited budget I’d go for 20-25 plus as in the summer you’d be covering your needs in total and getting a good income from exported power and in the winter you just charge the batteries on cheap overnight tariff rates and almost never need expensive daytime grid at high prices. Good luck
Yes definitely buy the most batteries you can, but even with recent cost reductions they’re still expensive, circa 5-20 years payback. Don’t get the 5.2 as they are only 80% depth of discharge, the 8.2 and 9.5 are 100%
Have you thought about getting a quote from a builder to late out that front gable, then you could just have the panels at the front might save you some money.
Thanks for the comment. Another person mentioned that on a previous video and whilst I had not previously considered it, unfortunately my wife is dead set against that.
I would switch the invertor to the same manufacturer as the battery one app. Also Octopus energy can give you a great tariff, and control your system with the GivEnergy setup.
Just got a quote myself from Ovo. Similar price but they specified the GivEnergy gen 3 inverter. Battery is a little limited on the peak output of 3.3Kw. I would prefer the GivEnergy All in One but they don’t yet quote for that (on the way). It’s also a lot more expensive. Thanks for the vid..
@@paulmannion7097 Thanks for commenting. I have noticed the charge and discharge rates of the givenergy inverters appears to be low compared to some others.
Thanks for the comment. The biggest spike i've seen from the heat pump so far was 2kW, but i'm sure with other appliances going simultaneously it won't take a lot for us to trip over the 3kW on a very cold day. I'll be drilling down into the inverter specs shortly. Thanks.
Not sure you are aware (not checked the other comments) but Battery only systems will be vat free from mid/end of Feb this year apparently so may be worth asking for an updated quote on battery only systems in March as could be up to 20% cheaper.
I would seriously look at doubling the size of that single 9.5kWh battery. I have the same size GE battery & in winter it's empty by midday after charging overnight - & we don't have a heat pump. Admittedly we are retired so we are at home most days so appliances are on during the day as well as overnight. I'm going to add another 9.5kWh battery to our system as soon at the 0% Vat comes in. For a sanity check against an outstanding quote I have from my original installer I asked Octopus for a quote to add more panels & battery to our system & they have politely declined because they are too busy!
Thanks for commenting. I'm doing my sums very carefully because the payback period on any battery is currently looking very very long compared to solar panels. Even utilising smart tariffs and selling back to the grid during peak times as well as benefitting from saver sessions. You are right, to make it work for me I do need at least 20-30kWh in the winter, but during the summer that's just going to be totally over the top so I'm not sure I can justify the capital investment.
I think your savings calcs are for PV only. Installers generally don't include battery savings as there are too many variables depending on your charge/discharge patterns. Also need to factor in the capital of replacing the battery (10-15 years) within your 25 year span for the PV
In this description, the direction on the compass of the two arrays appears to be 129º for the 5 modules and 310º for the 12 modules. They are claiming a return of about 4700kWh, I really cannot see that happening, considering the position of the two arrays, I would be interested to see if it materialises, assuming you're going ahead with the installation.

Just got my inverter replaced yesterday so back on line for the first time in 8 weeks. I have a 9.5 battery and it's a must have as it's better to save what you are importing then to export as a lower rate.
In your excel sheet, I see the battery only installation for 9.5kw is 3459. Does it include any inverter(AC or Hybrid) and installation!! this is the cheapest option if it includes everything!
DO NOT BUY THAT SYSTEM! With your shading issues you want to buy **SHINGLED PANELS** - its worth paying slightly more for them as the impact of shading on them is MASSIVELY reduced. Instead of having Half Cut Panels - ie each panel consists of 2 separate producing segments - Shingled panels have 144 segments, so shading on 1 of them reduces output by 1/144th etc. Don't let anyone persuade you to use optimizers, shingled panels are the better option in terms of cost and future failure/maintenance (optimizers have fairly well established failure rate of 10-15% over 10 years). That would then mean you would need to erect scaffolding to be able to replace them, panel failures are significantly less common. . GivEnergy kit is good but DONT buy the 3kw AC Coupled with 9.5kw Battery. You are limited to 3kw peak AC output from the battery. , Instead get the GivEnergy AIO - that's 6kw AC Coupled with 13.5kw Battery, Max peak draw is 7.2kw and continuous is 6kw. . If you know your peak energy draw is going to be consistently more than that (6kw) then you might want to look at different options. . Potentially you could look at Sunsynk 8kw Hybrid, or 15kw Hybrid (the only product currently on the market offering 15kw Single Phase connection) or it might work out cheaper installing 2 x 8kw Sunsynk Inverters in Parallel. You could then split your panels into 4 separate strings which again would help with shading. Whilst this is overkill for your PV Array the important factor here is ensuring that your house demand is met by your batteries and maximizes full use of the Solar & Batteries to load shift to cheap rate time of use tariffs. . Growatt have been in the business for a while but are not generally considered Top Tier Inverters. There are for sure on the cheaper end of the scale too. . With the potential for shading issues it might be worth considering Fronius Inverters.

Also Sunsynk are manufacturer agnostic when it comes to batteries giving lots of options.
Have a look at the Gary does Solar videos for lots of detailed explanation of things like inverters, shading, battery sizings. The Octopus quote doesn’t look good I agree. Whilst you have the scaffolding up it’s best to maximise the panels you are installing as it’d cost another £500-1000 just for scaffolding to expand in the future. Having panels on different sides of the roof will give you a longer solar generation day. I’m not sure why Ovo are quoting for an AC coupled system, a hybrid inverter is one less box to install thus cheaper and will have about 5% less energy losses when charging your battery from solar. GivEnergy batteries and inverters are good, lots of people have them and there’s an active community forum
Thanks for the comment. I have been binge watching gary does solar recently to get fully up to speed. Totally agree that it seems sensible to maximise the roof space whilst scaffolding is in place.
FYI. I know that a small electrical company installing solar can purchase the givenergy 9.5 KWh battery at £2.5k and I’m sure the likes of octopus and OVO can get them a lot cheaper.
Thanks for the comment. The generation figures are 10-15% pessimistic from my research. I've not come across any other online or locally who have performed worse than their generation forecast. It appears that nearly all of the installers use either the opensolar or easypv system to generate their proposals.
thank you for another really good video, as an ex IT Project Manager the thoroughness of your spreadsheets is much appreciated 🙂...If i'm honest I'm a bit shocked at the 'price gouging' by Octopus in the markup they are adding to third party supplied products.

Thanks for the comment. The reason I went to Octopus first of all was the knowledge of how aggressive they've been with pricing in the heat pump market. It doesn't seem to have carried over to solar at all.
I'm impressed with the amount of power you get from the NW facing roof, the JRC prediction is 3800kWh/year for the 14 panels. However, that battery quote is huge. You could get 14kWh of off the shelf 48v lifepo4 batteries for that. I'm not impressed with the givenergy inverter stats either - they're expensive, and are relatively low power when it comes to charging / discharging the batteries.
Thanks for your comment. I am leaning towards a SunSynk inverter for this reason. It seems to have higher charge/discharge rates and plays nicely with any type of battery. The NW roof also surprised me. There seems to be a growing consensus that blanketing the whole roof space, no matter the orientation, should be done.
A;ways take the payback periods with a pinch of salt as there are some big assumptions in them plus of course you battery and inverter are likely to need replacing in 10 to 15 years depending how hard they are worked, warranties and degradation. No installer ever factors in that you will have another capital investment or two to make over the 20-30 year lifespan of the panels. I agree with many on here about sizing your battery properly and not going to small however it need to be appropriate for your needs now and in future noting that the inverter and battery are the more expensive parts of the system and will need replacing so if you go big it costs more now and in 10 to 15 years. One of the big things people overlook is the Inverter size and capacity both the recieve but more importantly output AC. It looks like yours is showing 3kW from the battery which could be limiting as many electric ovens run at 2.4 to 3 kW so any other base load would take a demand from the grid as well. My system has a 6kW Hybrid inverter which for our smaller energy needs has been sufficient when cooking Christmas Dinner (oven, hobs TV's everyone home).
Thanks for your comment! I've been proactively calculating my own payback based on different forecasts and assumptions, you can see them in the last 2 videos on my channel.
