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…

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…

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…

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,…

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…

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…

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…

If you’re short on time, here is the quick summary of what’s changing and why: Greener Nights ends on 31st July: You have one more month to earn rewards under 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…

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…

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…

Octopus IOF Not charging battery
After Octopus paused my discharge yesterday , to help the grid, today it has not allowed charge by1330 and the battery percentage is 18%. Bearing the mind that if , I get max solar before 1600 I might get up to 80% by then I can't help the grid at 1600-1900 indeed I could eventually end up buying power at peak rates.…

The best Solar export tariff... for small business?
Greetings! I recently helped a Dental Clinic in Maidstone with their PV system. Their reasons for investing in Solar were straightforward: 1) Save on energy costs (they import in excess of 9000 KWh per year) 2) Provide whole Clinic backup with instantaneous switch to battery backup in the event of an outage 18 X 515W…
