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…

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,…

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…

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.

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…

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…

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…

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.

Our quest for Net Zero one year on
Hi all, It's been (almost) a year since we upgraded our solar install and added the Powerwall 3 battery, and the numbers are in for June so I thought I'd take a look at our numbers for the first year. The PW3 was actually commissioned on the 11th July 2025, so we are not quite a full year and the full 365 day numbers can…

Greener Days EV Charging Octopoints
been charging our EV overnight on 🐙 ‘Greener Days Forecast’ for the last couple of months and today got our email from 🐙 saying we had charged 4 week long streak on greener days so received 80 octopoints - which equate to 10p - obviously aren’t doing it for the money 🤣 but it’s good knowing we are charging when the grid is…

Location of batteries and inverter for solar installation
I have a consumer unit, the meter and the mains input cable located at one end of a long house and another consumer unit in the garage. Distance between them is 24 metres with a 100amp cable connecting them. Can I place the battery and inverter in the garage. Solar panels could be directly connect to either end of the…

Should I go for another quote though I like what I have so far?
Hi guys and thanks @ArtyJ931 for signposting me here. This is being written in a rush as I have to get to work soon, but having decided to go for solar, we arranged two meetings with companies. One of these came recommended through some sort of clearing company, the other seems to have bought our phone number off said…
