8.5 kW Bifacial PV System: ~7 year ROI: Fact OR fiction?
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…

Cost of adding batteries to existing PV system.
I'd always shrugged off doing this as the return time would be too long. But I've recently seen some near-new battery setups being sold on FbMarketplace for prices that are hard to ignore - sometimes as little as £1.5k for excess of 10kWh. The Q is, what would the additional costs be should I jump? Ie, installation, and…

Export Supply Number???
My smart meter measures export as well as import and the export reading has been assigned its own MPAN. But my export statements not only show this MPAN but also a full supply number. The bottom line of my supply number is my export MPAN but the top line reads: 08 0482 781 Is this normal or a quirk of my export provider,…

Solar panels - portrait vs landscape orientation
Hi, I'm looking into designs for solar. The more I read / speak with 'experts' the more confused I become. Gemini has been useful, but also gets confused and has to be challenged! Anyhow… It seems that without shading this doesn't matter. Your choice might be down to which orientation allows you to get the number of panels…

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…

Not sure how to progress or to ask correctly. Quotes for solar and(or not) battery
We used a tool on this site (not forum) to get some quotes in. On line with a phone call. Also tried our supplier. Quotes come in and vary too much and some pricy but after reading a few threads here, realise we need the local installer and a visit for on site survey. Probably forget those quotes out of hand. And when I…

How long did it take for your solar export tariff to be set up?
More of a nosey question to be honest: How long did it take for your solar export tariff to be set up after your system was installed? Had mine installed April 21st, and only just got an email from octopus that it's set up for export, I've lost over 1000kwh of export 😢 reading the meter today. Anyone had any luck asking…

Connection of a replacement battery to a Solax X-Hybrid inverter
Following on from my earlier thread (below), Solax have sent me a new battery to replace the one that's subject to a recall. I have a Solax X-Hybrid inverter SK-SU3700E. This has two power wires (red and black) and a data cable going to the battery pack. The new pack looks very similar, so I can see where the wires would…

EV Charging losses and Vampire drain.
This topic was touched on in a recent exchange on the BEV thread but I felt it would be worthwhile having a separate thread as other issues were overshadowing it. When I first got an EV I didn’t have a wall charger and just used a granny plug (230v, 2.3kW I think) and never took much notice of charging cost. I would just…

Telsa vs Sigenergy
Hi, Pros and cons of Tesla PW3 vs Signergy 2 x 10 batteries with an 8kw inverter please? Average 18kwh per day, 6700kwh per year. Lots of aircon and computers/monitors used for a couple that work from home all day. 19 Aiko 515w panels, but 10 of those are North facing so half as efficient as the 9 on the South roof. Thanks!

Green & Ethical Investment News and Suggestions
This is a subject that crops up occasionally on multiple threads, so I thought it might be useful to have a thread where we can share both news and also investment ideas that we find.
