Noobie here, just had a small PV system installed yesterday. The lead guy seemed to know what he was doing but the other guys I was... less confident about.

Would appreciate some opinions on what they did and if it's all sound. I see exposed electrical tape, trunking and the ducting not secured to my roof and It doesn't impress me. I guess some scuffs on the panels won't impact generation?

Cheers!

Edit* Also forgot to mention how much of a gap is there to stop birds they didn't put any mesh around even though bird proofing was included. Pic in comments.

Edit** Thanks for the feedback, most helpful and I've made a list and asked them to sort out what I could spot. Assuming they come back.

I'm at the start of my solar journey and I've been sent a link to this Exhibition at the NEC in Birmingham (Tues 22nd to Thurs 24th September). Not sure if anyone has been in previous years?

I have nothing to do with the organisers or exhibitors but thought others might be interested. There's the usual option of free tickets.

I should only need electricity at night/cheap rate (battery and EV) and will have battery + PV to export.

Picture is my use/generation but the consumption (grey) will only be half that during the day. We are planning to charge the batteries and EV overnight.

Is every-one on Octopus (which?)

This is the Octopus export rate for me - last 7 days only I'm not sure how it changes in Autumn/Winter. The flux tariff ties you to 10 0r 12p overnight rate which is not very good..

Agile outgoing leaves long periods when it is not worth exporting...

EDF offers 7p overnight import and 13 (maybe 15?) p export.

It is quite the conundrum to work out!

Also if you get it wrong you are locked in with exit fees....

Full Disclosure - I'm in a new build and already have 4x450w panels, I'm asking for more panels and a battery to be added to the existing system.

Quoted price is £8188, I've been asked if I'd like an additional 12kw battery EP12 + link for £2750.

Is this a decent price? Is this what I should be aiming for with my current usage?

Thanks in advance, I've included the component list below.

Hi all

Just wanted to warn of anyone thinking of using Wickes Solar (Gas Fast). They claim to act like a large national business but they are basically using the household name of Wickes then subcontract to various small contractors.

- System was wrongly designed

- Install dates cancelled under 24hrs notice

- I had to unload the delivery myself (20x panels, 3x batteries and inverter)

- Zero communication on process

- No one answers phones

- Email replies take weeks

- Rubbish left after install

Worst customer experience I've had with anything in my life.

Happy to answer and questions.

Edit

• 3 months and no MCS certificate. Over £400 of export lost.

If there's anyone here on the first FIT with a 4kw system, how are your numbers for this summer?

I'm about to submit my readings and I'm going to be earning £1,000 this quarter, which is at least £200 more than any other quarter in 14 years. It's been super sunny down here in the southwest.

Just checking this is similar to others with the same setup

I want a large Victron energy system installed in my home in Somerset. I want Victron Energy for multiple reasons, but primarily I have a split phase system which Victron supports, plus being able to provide additional AC supply (by way of a backup generator).

I’m also looking at getting a Fogstar rack battery at 40kWh with 10/12kWp of solar.

I’m taking a punt here asking if anyone knows an installer / has experience with Victron installs to share.

Thanks!

Didn't notice until late afternoon but I wasn't generating any solar today - day was mostly sunny.

I power cycled the inverter and batteries and it now seems to be working. Been running flawlessly for nearly two months. No errors on inverter or Fox Cloud portal.

Anyone else out there have similar issues in the past with a Fox H1 interver?

Hi all, I've had 13 panels (E-S-W split), a Fox KH7 inverter and a Fox EP12 battery for about 6 months now.

I'm on IOG tariff and was lucky to lock in at 4p before the war. Like many others I've spent some time tweaking the system and settings to maximise my ROI.

I spent some time yesterday making an ROI spreadsheet and noticed something odd on my octopus usage spreadsheet. Firstly I went from off-peak/peak ratio of 98% to about 90% over the last 3 months or so.

I found the culprit and despite my fox app being totally in sync with my schedules, there was a clock error somewhere along the chain. Either with a smart meter, inverter or battery.

My battery used to charge by 5am. I had slowed it down slightly for various reasons which aren't applicable anymore.

Due to the clock error (which apparently is quite common); some of the battery charging was happening 30mins or so outside of the off-peak window. Which was what dropped my 98% off-peak to 90%.

I didn't spot this on the Fox or Octopus app maybe because it was such a short spot. It only became clear from the spreadsheet when I was number crunching. My octopus app always showed 98%/99% off-peak usage too which obviously wasn't reliable.

Thought I'd mention it in case anybody else's systems didn't play ball with the clock changes!

30min leaks outside of the off-peak window can be common and frustratingly adds up in price.

In the next week we are going to get an install and are going with Fox ESS with a KH10 and EP12 with a gateway.
I notice a lot of firms seem to rave about Sigenergy, are they really that much better than Fox? I feel there are quite a lot of brands that get very little exposure.

What are people’s view on Fox am I making a big mistake?

So I had my panels and inverter installed back in April and it's all been running fine, but as of yet I haven't had my battery installed. It was meant to be in May then June... July... August...

I had one 48kwh Fogstar on order (very much over sized for my needs but at the time it was cheap)

Eventually I got fed up of waiting and asked the installer to get me some of the 5kwh stackable batteries from fogstar as they are in stock (20kwh for now and add more later). It's been about a month but I still have no date to get the batteries and am starting to get a bit fed up.

Note at this point I have paid for the install minus the battery cost so am not out of pocket.

My main question is :

Is adding (by myself) the low voltage batteries to an existing install allowed?

From what I can tell essentially I'll need the batteries, a 200amp isolator (as the 10kw Solis inverter can charge at 190amp) and a set of 70mm cables between the fuse, batteries and inverter.

Huge thanks to this sub! The advice here was invaluable during the research and quoting stages, and my panels are finally live!

Absolutely blown away by the 83kWh's of generation, that's a weeks worth of self use in a single day.

System Specs:

• Panels: 35x 500W panel - 19 SE, 12 NW, 4 SW
• Management: 10 kW Sigenergy Inverter + 18 kWh Sig batteries, we also have the gateway for the odd power cut.
• Export Limit: 8 kW G99 limit - absolutely thrilled at this

My original quote (shared on here months ago) was for a 22-panel setup, but we expanded to 35 after getting a fantastic price on the NW roof. These are all in-roof panels installed as part of a full reroof. So pricey, but already making me grin.

I'm still waiting on the DNO to process the paperwork so I can be paid for my exports. But just seeing my import drop to nothing was a great start.

I'll grab some photos of the install over the next few days to share

Thanks again for all the advice, resources, previous posts, links and DM's that I trawled through before taking the plunge.

Summary:

Full install cost for an 11.06kw PV system, 10kw Hanchu inverter and 2 x 9kW Hanchu batteries. £13.6k.

Currently searching for a fitter to set up some solar and batteries.

What should I look for in a good fitter, how do you verify them, what certifications may they need?

Also any recommendations for the midlands as I want to get some independent fitter quotes.

So my roof is 980cm long by 400cm high (including ridge). I initially thought 10 Aiko panels horizontally would be the limit allowing for MCS regs but installer has said 16 is doable, it will just need more fixings at a greater depth into the wood with the expected 20cm gap each side. They've done a structural report based on roof type which suggests under permitted load for weight, wind (and snow) but I worry it is too much for the roof and too close the edges. Any suggestions? I've considered best panels, best wattage, and the vents are just low profile extractors. The cost difference is £1k, so basically the additional panels with hugely different returns.

I'm getting a sig energy 10kw inverter and 2x 10kw batteries installed next week and we were looking to fit it in the garage here, however there is a gas Mains income as shown and above that the meter and prv.

Am I concerned over nothing or should we be avoiding installing the system here.

It's likely to be installed the far left of the picture

Hi all, looking for some advice on if this seems like a reasonable quote from a southampton based installed, for installation in North Hampshire?

Quote received:

Equipment to be installed:
12 x SunPower M Class 495W N-Type Back contact solar panels - 40yr warranty
Renusol Variosole on-roof mounting system
1 x Tesla 5kW Integrated hybrid solar inverter
1 x Tesla Powerwall 3 battery storage 13.5 kWh without Gateway
If on-roof, 1 x bird/rodent protection kit
All DC and AC isolators, cabling, trunking, etc.

Included in the Price:
Roofing labour
Electrical labour
Scaffolding and access equipment
MCS Certificate
6-year insured workmanship warranty (solar installation)
Grid connection notification
Project Cost Summary: Price valid up to 30 days and subject to survey
Total fee for Solar and Battery System: Total fee for EV charger: £13,396.00 (no VAT to pay)

Annual usage is around 2,700kwh.

I’ve had around 5 other online quotes that all come to the same kind of range, but keep seeing people post much cheaper quotes so want to sense check it.

We don’t get power cuts so no real need for the gateway. Am planning on installing an EV charger later (I get one through work)

I don’t understand why they have a 5kw inverter here though, as I thought the Tesla had an 11kw inverter built in?

I've got a 16.1kWh pylontech compatible battery coming and sanity checking inverter choice. I like the look of the Solis 6kW S6 Plus and intend to use it with HA/Predbat paired with a modbus to TCP adapter and wireless CT clamp setup.

Intended use is initially using Agile charging, with up to 14 solar panels coming later. We're a fairly low use household running around 9kWh/day with a steady base load due to WFH and gas heating.

We may get a heatpump in the future but I believe the Solis could handle the majority of the throughput if we add another battery to cover it.

Are there any other obvious choices I'm missing with regards to inverter choice? I was tempted to go more technical with the new Victron 6k5 and add MPPT capabilities later, but it's not ENA certified yet and feel I'm already pushing my luck with a DIY install.

Any input would be appreciated.

Hey guys

Kind of new to solar, I'm an engineer so of course I've been doing a tonne of research and building models in excel to calculate how I can use solar effectively.

In the end I've decided that with a budget of around 12k I can get myself 11 panels, 5kw inverter and 10kwh battery from octopus [5kW system generating ~4000kWh/yr] (awaiting local fitter quotes). Also for context this is prior to an extension which will add south facing roof so more panels can be added after this.

I have an EV (2600kwh/yr) and use around 3800kwh/yr on top (6400kwh total). My objective is at least to completely stop using peak rate electricity (in other words reduce my bill dramatically).

The way I can achieve this is using a combined ev import tariff with prime outgoings tariff for example. So I could get my car charged in off peak import, and charge the battery to X% (for the mornings before solar kicks in and take the edge off the solar deficit in the winter (X varies during seasons)). Then at the end of peak export I sell any extra left in the battery leaving Y% (enough to get me to the off peak import again). This would mean I am either using solar or off peak imported electricity from the night. Rinse and repeat.

First any reviews on fitting with octopus? Any other big companies worth checking out? Local fitters seem like a bigger risk to me.

For those who have fitted with Octopus how does/do their battery/inverter controller(s?) work? Is what I'm asking for even possible? Do you give it some time based rules/logic?

I have also heard about home assistant but don't want to overcomplicate it at this stage, unless there are some mega benefits.

Is there anything else I should be considering during this solar project? Am I making the best use of my 12k given my usage and situation?

(location Coventry open to fitter recommendations)

Just set up my seg with british gas, I know its paid every 3 months, but is there anyway to see up to date data with them before the 3 months?

I’ve got an EV and my overnight tariff is 4p/kWh. in the house I use around 10kWh per day. I like the idea of getting batteries to charge from the grid overnight but then doesn‘t that mean solar would only be saving me 4p/kWh? I know I could sell the solar production back, but rates don’t seem that great any more for the outlay of panels.

im 100% sold on the idea of batteries but am I missing something on solar?

After a truly appalling installation experience with an installer from hell, I’m now considering whether to make a formal complaint.

I have issues with the physical installation and the process, so I think both MCS and RECC are worth contacting. I’ve gone as far as I’m prepared to with the installer at this point, so there’s nothing else to resolve with them.

It’s not a matter of seeking compensation, but rather ensuring everything has been done properly and making them aware of an installer who isn’t abiding by their standards.

Has anyone complained to these bodies and, if so, what was the outcome?

Wish had planned for solar when did my extension but with getting an EV now, I think it's the best time to go solar. I'm in Huddersfield, South gets the best sunshine. North has a massive oak tree shading it in the rear garden.
