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,…

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,…

Tesla Powerwall - App problem, Tesla not responding
My Powerwall 3 was installed in October 2024 and, until last May, has been brilliant. I'm on IOG and, apart from a Christmas, we've only been buying electricity at the cheap rate (Currently 8p per kWh). Last May, although I really didn't need to, I decided to update the app with the current Octopus pricing. The app had…

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.…

Biting the Bullet

We have a relatively new boiler, so thinking about a heat pump further down the line. A picture of the house is above - we're in South East Scotland…

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…

Solar PV 2 engineers gave conflicting diagnosis (SMA sunny boy)
I have an 8-panel solar PV system installed in 2012 with an SMA Sunny Boy inverter. The system has apparently not generated since around 2018. Engineer 1: Inspected the system around the inverter/loft area. Measured approximately 2.4V on the PV strings. Said the inverter was probably not the fault. Suspected a fault…

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…
