Solar options (mind field)
Hi I'm looking for some advice for solar panels Who's the best companies to contact ? Presume 3 quotes . What kind of price will I be looking at ? I did have one quote a while ago but I'm sure prices have changed since then (2022) We used 7000kwh annual. What's the potential savings ? What's the best kit to have? Property…
Are solar panels worth it
Hi we’re thinking about solar panels. In the process of getting a quote from octopus and an Independant guy. pensioners, live in a bungalow. I’m disabled so home all day. Main problem is conservatory - 7mx 3m glass roof. A lovely space but very cold in winter - thought about warm roof but worried about light impact on…
Renewables: "talking 'bout my generation"
Please forgive the corny thread title inspired by The Who but this post on the bloated 'how do I make the most of it' thread prompted me to initiate a new one... Well, there was yet another misty and bleak start in North Notts today (Thursday), but my SSW 3.92 kWp system was generating around 3kW for just a few minutes…
EV Discussion thread
As some of you will be aware Martyn1981 has clarified the purpose of the BEV news thread he started - “the intention for this thread was to enjoy the transport revolution and share BEV news. That might even be described as a 'cheerleading thread' I suppose, and I'm not sure why that would be wrong on a Green & Ethical…
Solar + Battery quote with EV
TLDR Hi there, I am new to the country and moved in to our new house last year. Still learning the new culture and etiquette on posting/discussing on forum so apologise if I am doing something unusual. We have a 3 storey house, south facing 35-45 degree slope tile roof. We have been exploring the possibility on having…
Battery Electric Vehicle News / Enjoying the Transportation Revolution
I thought a more specific thread/title might be useful for posting news on BEV's (and EV's in general), given that we have threads to discuss the minutia about EV ownership, but perhaps a thread just for the news might be useful. Disclaimer from the start, BEV news can easily become Tesla heavy, so posts, especially mine,…
Solar PV Gross vs NET output
I'm in the position of trying to sell my house and currently having an EPC certificate produced, the problem that I have here is that the MCS certificate for the solar array says I have a NET capacity (kW) of 3.82 and the EPC inspector is asking what my Gross capacity is which I don't know. What I have is 15 x 255W panels…
Ripple Energy wind farm?
Has anyone looked at Ripple Energy? I'm thinking about it, but not too seriously. I don't have a lot of time to investigate it and if anyone else has taken a look I'd appreciate their thoughts before I take a more serious look.
Moving solar export (and elec import) to EoN from Octopus
I'm now at the end of my fixed deal with Octopus, and I'm a bit concerned that Octopus will drop their export rate from the current 15p, so looking at moving to EoN - it's 1 year fixed at 16.5p if I change my electricity supply to them as well. Does anyone have advice how to do this with minimum impact financially? I…

The Alternative Green Energy Thread
In an attempt to maintain harmony on Martyn1981’s Green, Ethical, Energy issues in the news thread, Mart and I have agreed that I will no longer contribute to that thread but instead start a separate thread which Mart has agreed not to participate on. The intention of the thread is that green energy issues can be discussed…
Considering adding another battery - inverter options
Hi all, At the moment I've got 4.8 kW of solar, a Growatt SPH5000 hybrid inverter and 15 kWh Seplos battery. I'm on Octopus Go so almost all our imports are at the off peak rate (average cost of electricity imports are under 10p/kWh). I'd really like to add another Seplos battery kit to have more storage and set us up for…
Extended Inverter Warranties
Our PV system was recently commissioned and is working well. We paid an extra £250 to extend the inverter warranty from 10 years to 15 years. We have received an extended warranty certificate from the manufacturer (Growatt) saying that the warranty ends in June 2039. That's just over 14 years from installation. Growatt…
Export tariffs - FIT, SEG, Octopus Outgoing Agile
I was a Green Network Energy (GNE) customer and have just emerged from the transfer to EDF as Supplier of Last Resort (SoLR). I still need to get my GNE closing bill but my EDF account is fully functional, which has let me sign up for smart meters (don't all shout at once). One of the questions EDF asked was whether I…
On-grid domestic battery storage
Hello! Right, as discussed elsewhere, battery storage for self generation (typically PV) is interesting (to some), and gathering momentum in the UK. So here's a thread to discuss it, and watch it develop. I've called it on-grid, as off-grid is so much more specialised. And domestic as commercial scale storage, or grid…
How "safe" are our inverters
Here's a headline from the Telegraph today: https://www.telegraph.co.uk/business/2025/05/15/chinese-kill-switches-found-in-us-solar-farms/ - from the article "The components found in the US included cellular radios capable of switching off the equipment remotely, raising serious concerns about grid security," So, are there…
Solar Panel & Battery System Quote (check!)
Hi all, bit of a lurker but I figured I'd sign up to use your expertise to help with a solar decision! I have been in a new build home for 2 months and I'm considering solar. The house is a 4 bed detached, with only me and the partner for now. I only have 1 month's bill which was about £70 for electric through Octopus…
Quote check: 8.1 kWp Trina + 10 kWh Fox battery for £11.5 k – 20 p SEG… sound about right?
Considering solar with battery. I've approached OVO as I like their overnight EV charging and 20 p SEG if I order the panels and battery through them. Can I get your thoughts on this please?
