EPC
I attended an EPC assessment today. Happened to mention I was planning a heat pump this year. The assessor said they would reduce the assessment score for electric heating because "most electricity comes from gas". I mentioned that last quarter more electricity came from wind than gas: " that's because some gas turbines…

Best mounting system for flat roof
I have a 2.4 x 6.0 m south facing flat roof that is just going to waste. Can any one suggest a suitable solar PV mounting system that would enable me to install more panels (4 portrait mounted i think)? Does anyone have experience of such systems? Prevailing wind is usually SW and can be quite strong at times as it blows…

Solar quote does this sound reasonable?
I’ve found so many spam sites and rubbish when looking at Solar so I’m finding it hard to know if these quotes are reasonable. The 2nd quote offers larger batteries and 2 more panels for the same money but I’m not as sold with them as a company. 1. local company with good reviews, via solar together scheme. Get good vibe…

I just sent this complaint to them as the takeover was in November and it's now February and I still haven't been migrated across! I understand that Shell Energy is now owned by Octopus Energy from November 2023. I am one of the many customers that is…

Any Solar only & EV users out there? Octopus questions
Anyone have solar only (no battery) and an EV? Best plan on octopus? my thoughts are: - Agile & agile outgoing over winter (Sept to April) - Flux over summer its pretty close TBH over the summer- but less stormy so less super low/negative, and hardly use any import over the summer (70kw + 100kw EV avg), so import rate…

One benefit of High Inflation?
Seeing the BoE inflation forecasts yesterday made me think about the impact on the FIT rates paid which are based on December RPI. Last year was around 7% increase but from the forecasts it would seem that we're likely to be looking at 15% or more for RPI by December so next year could be quite a massive jump in the rates…

Sunsynk hybrid inverters
I'm considering a Sunsynk inverter to go with my solar/battery installation, as they have islanding capability. Has anyone got any experience of them? How easily do they interact with other makes of battery and with Octopus TOU tariffs? They don't appear to be on the Octopus approved list, yet.

Eon offering £100 goodwill for mis selling battery capacity, fair?
I purchased 12 panels and a 5.2 kwh Givenergy battery from Eon, at the time of the quote I was told that the battery had a usable capacity of 5.2kwh. I have recently had a email from Eon advising that they made a mistake and the battery only actually has 80% of it usable capacity, which they now quote as 4.2kwh They are…

Panels vs Inverter - how much oversizing makes sense?
Hi, I'm trying to get an idea on sizing, if we give up on anything more sophisticated and just stick to G98 limits. Suggestions from installers range from 4.2kW to 6.8kW, all using a 3.6kW inverter. Are there any tools or rules of thumb to estimate how many hours per year, or what percentage of the time, a given…

Can a G99 agreement be taken on by a different installer
Hi, Scenario is that one installer started the process with SSEN (our DNO) and reached the stage where our proposed project was approved. Subsequently the deal with that installervis virtually dead due to series of delays caused by their design errors. If I end up ditching them and turning to an alternative installer, does…

Fishy phone call about my solar
I had a phone call today from a company that claimed to have "taken over monitoring your solar installation". I wasn't aware that there was any company providing monitoring, so that's the first thing that smells.Apparently a fault has been reported by the monitoring, but I cant check it on my Solar Edge dashboard and they…
