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…

8.5 kW Bifacial PV System: ~7 year ROI: Fact OR fiction?
Updated system size is 8.45kW at a total installed cost of £10.5K. Current ROI is forecast at 6.5 years. Hi there, I've recently been quoted for solar panels from 3 installers referred by Solarguide. My guidance to these companies was maximum solar power yield per panel for their proposals. Quote: The LG panels are dual…

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…

Meat:- Food animals that are "fed naturally" as in grass fed cattle offer better nutrition than grain fed, steroid enhanced animals pumped full of…

Solar Quote views
Hi everyone, I’m considering getting solar and have a quote through the Solar Together scheme — where installers bid in a reverse auction for the work. I’d really appreciate your views on the quote! Background We’re in our late 40s and plan to stay here long‑term. South‑facing front roof (see image below). Annual…

EcoFlow Stream "plugin" solar
Back in mid-March I ordered a "plugin" solar PV bundle from EcoFlow: EcoFlow Stream Ultra 1.92kWh battery with four MPPT inputs Four EcoFlow 450-watt solar panels This cost me just over £1100. I thought I'd share my experience here in case anyone else wants to do something similar. Edit 29/07/26 to add: a system like this,…

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,…

Lux ac battery controller
Thought I'd start a new thread for the Lux battery controller as suggested on the battery storage thread. To kick it off, I notice there is an entry on the web portal stats under "history data" for battery temperature (tBat°C) but mine just shows zeros. There's also entries for max and min cell voltage but again, no…

Plug in solar (only solar) legal from 27th August
As of 27th of August it will become law that you can plug in an 800w micro inverter with attached solar of up to 2000w into a standard UK power socket. This law change only applies to plug in devices that generate from solar only and does not extend to any device which stores electricity for later use (aka plug in battery)…

Octopus Energy Streams: An add on to Intelligent Go
https://octopus.energy/blog/streams/ Seems like a way to get more than 6 hours of low EV charging rates. No way to predict when the additional cheap rate hours will occur but the whole household's import benefits from the lower EV rates. I expect this is designed to take advantage of the negative pricing that is taking…

Nearly caught with a different Solar scam
We had a phone call last Friday from an unknown caller wanting to arrange to read our solar ev energy meter. He wanted to come on Monday but we told him that today was the first available date. I felt somewhat patronised by the tone of the call! He arrived at the arrange time this morning and just had a perfuctory glance…

New Solar and Battery installation
Hi all, I've been a lurker for a while but signed up to the forum today as we are in final throes of purchasing a new house. As part of choice of house, we wanted to install a solar and battery system on the property. We will also be looking at if it is a suitable property for replacing the gas boiler with an air source…

Rooftop bifacial panels (with reflective background) vs. Monofacial
Thought I'd share some real world data from my own roof and my immediate neighbour's roofs. These are 4 X LG 400W bifacial panels, originally installed in 2019 and recently repositioned in a row on our ENE aspect. Average generation across the last month was 59KWh. Note how the panel (1.3.8), with one side unrestricted…

Solar Panel Potential
Hello all, I hope you might be able to help me – I’m looking for advice on a property I don’t yet own to assess its potential for solar panels. The property is in NW England, and although the property is south-facing, the roof is, well, let me show you…. This is the south-facing rear. The estate agent's drone shot. The…

Sigenergy hybrid inverter configuration
Hi, I'm thinking about a Sigenstor system. 20 panels across 4 roof aspects (N,S,E,W), all with different shade factors. I'm thinking of a 8 kW SP inverter to allow 3 strings of panels. If my DNO is limited to 3.6kW, do I have to have a 3.6kW inverter or can o/p to Grid be throttled to 3.6kW. If o/p throttled to 3.6kW, does…

Uhome LFP 2400 Voltage Falling Under No Load Conditions
Hi Folks, In June 2022 I’ve had a Lux ACS 3600 and 4 x Uhome LFP 2400
batteries installed at my property (supplied and install by competent person) to
store the surplus solar energy from an already installed roof top solar array.
The system I thought had been working fine and was configured for 90% depth of
discharge (DoD)…

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…
