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…

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,…

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,…

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…

Solar panels in Scotland - worth it?
I'm looking at a 9-panel / 4.2KWp system with/out about 11kwh of battery, in central Scotland. House is almost exactly South facing an clear of obstructions. The quote details reckons we can produce about 3500kwh/year and our consumption is about 4500kwh. Cost is about £6,250 for panels only, £10,000 with Fox11.5khw…

Adding to my solar system
Hi all, just wondering if it would be worth adding to my system or not. Either a battery or extra panels. My current system consists of 4x west facing 400w panels and 2x east facing panels. With a solis inverter. I have a flat roof which could possibly add 4 panels, but I'd be concerned with the extra weight on the roof.…

Anyone else rethinking heat pump plans because of the heatwaves?
Hi all, I was all set on completing the last major piece of our home decarbonisation puzzle with a quote from Octopus for a heat pump. It was about £3.5k after grant for HP, hot water cylinder, a new radiator and replacing an existing radiator with a larger one. We already have 4.8 kWp of PV, 2x 15 kWh batteries and an EV,…

Free Electricity for 2 years!
Being absolutely sick of the up and down energy market I decided to take action. Using all the fantastic tools and advice give by Martin I set off in search of an answer. Having an East to West facing roof I though I couldn't have solar panels, but I can!! I got a quote for 12 panels, 6kW inverter and a 10kWh battery for…

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…

Heat Pump integrated into Hot Water Cylinders (Vaillant, Daikin etc.)
Seems like a sensible way to reduce hot water heating costs without going with a heat pump for the entire household. I wonder if any users/ owners are out there? https://www.ariston.com/en-uk/products/heat-pumps/air-source-heat-pump-water-heater/nuos-plus-wifi-uk/

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…
