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…

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. I've noticed that many schemes are as financially attractive as other general investments, so there's no penalty in targeting your monies…

So far, a few issues. (Gettit?) Cough - Sofar ME3000 SP
Ok, all set up. Followed the correct starting up protocol - no PV, battery connected, power on. Into settings. It seems to be going ok, but I do have an ID57 fault as my battery is currently at -21oC. I didn't connect the COM cable when I first set it up, as I didn't know if it was compatible, but I have since tried it…

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 e 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…

Plug in solar question
yes I know it’s not legal yet but it’s still a query. Say you have a solar panel in your garden, this is plugged into an inverter which is plugged into the home via a socket. Let’s again say that the panel is in total sunshine all day and creates 500 w of solar energy which shows on the inverter. So in the house u put…

Is Solar worth it for me?
Hello all. I am considering having a Solar PV system with battery storage installed in my home. I had one in my previous house which was installed in 2012 when FIT was just taking off and it was financially worthwhile. I now live alone in a 1 bedroom bungalow and my elecricity usage is 1115 kWh per year which I think is…

Solar Panels - who to trust?
Hi, We use 6,700 kWh per year. We're in the process of getting quotes from 4 different places. The configuration is pretty similar for all of them. 8 x panels will fit on our South facing roof. 9 will fit on our North facing roof. A battery in the realm of 9kWh of storage and a 6kW inverter. We have a slate roof and it's a…

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…

CT Clamps - some Qs.
Well, got all my bits, and now just need to join them together; 3 of 5.7kWh Alpha-Ess batteries, Sofar ME300SP AC-coupled inverter, and all the gubbins. The two CT clamps have short wires, so I need to extend them. I understand Cat cable is good for this. Q1 - for neatness and convenience, can I share the same Cat cable…

Wickes Solar Panels
We are getting a new roof fitted Leeds in August, so thinking about getting Solar Panels too. We use 5K kwh per year and have an EV. I have followed Martin’s advice and got quotes from the 3 suppliers Glow Green, Project Solar and So Energy, using the Federation of Master Builders tool. I have also got a quote from Wickes.…

Best Solar System for me
We're thinking of installing solar panels. I've been doing a lot of reading around including looking at threads here. Still quite confused about how to work out the best system for our situation. We have a detached house with an unshaded pitched roof facing SSE, and another roof facing NNW. Each roof could easily fit 12…

Inverter replacement (?) - Newcastle
Can anyone please offer me any guidance with who I should contact to check my current set up? We had our solar array installed in 2011, so receiving the fit generation payment, and it is still using the original Sunny Boy inverter. The installer has long since gone bust. Everything has been working fine until recently when…
