Hi, We are moving house and our buyer doesn’t have the budget to cover the cost of the full system (Panels+Inverter+Battery) so we were thinking of selling them the Solar install and inverter only and then either taking the battery with us or selling it seperately. Can anyone advice on this, has anyone ever done it before. I understand that the inverter + solar panels can happily run without a battery present, is it just a case of powering the system down, isolating and disconnecting the battery? The system is a gen2 Hybrid inverter and a gen2 9.5kWh battery
Thanks
Yes you can split it as you suggest, the inverter will work fine with just the panels and no battery. However the second hand sales value of your inverter or battery is negligible, there just isn’t a market for used kit, especially as it has to be installed and commissioned by an authorised installer. You might get £1k for the battery if you are lucky.
If you are moving to another house then you could move the battery to that house and just pay for a new inverter and panels. A new inverter would be £500 or so, plus the cost of panels plus scaffolding.
If you remove the panels from your house and take them with you, it’ll cost you £1k for the scaffolding to take them down, so hardly worth it.
To be honest I’d try to find a way to come to an agreement with your buyers to let them buy everything at what they feel is a fair price they can afford. You won’t save much by trying to take the kit with you.
Or just give it to them, but if you can make some extra £, then do so !
Thanks for the reply, this is exactly along the lines of what we were thinking. We figured removing the entire system and re-install at the new place plus re-commissioning was uneconomical, so splitting the system seemed like a logical option to claw some of the cost back, but I can see that selling it might not be so easy and if we take it with us then we’re tied in to getting another Givenergy system for compatibility.
If you do consider splitting the battery, I would be interested in buying, to add to our existing system. Let me know if so, many thanks.
There are three listings (same seller) on ebay right now for his GivEnergy kit. A 5.2kWh battery for just over £500, and two sets of an AC3 inverter with a 9.5kWh battery for just over £1000 (for one inverter and battery).
I’d love for more storage, take away a bit more winter export stress and whether I could do a “heart over head’ justification for some more battery capacity I did some man-maths calculations of what I would save with cheaper rate vs day rate import from the larger battery in winter, and what I’d make from rate arbitrage in the summer charging overnight on Go and exporting more solar.
Total income from one extra 9.5 battery was less than £200 per year.
So if I could get one at near to the listing price, the DNO gave me the full extra export capacity, and my installer charged around £500 for installation (so £1500 all-in), I’d be looking at a 7-8 year payback which I didn’t feel was good enough.
Plus export rates are likely to drop in the next few years so payback will extend further.
I get adding a cost for batteries, I am currently doing the same. But solar is not a removal item like a washing machine etc. Not sure how you can negotiate for solar panels/inverter. Batteries yes, the rest surely is a default fixture and fitting to the house.
I have been quoted £1200 to remove my 3x AC3’s and 9.5 batteries and install in another house.
Hi, I’ve been away last week so only just catching up, I only just saw your message but in the mean time I have put the battery on EBay, the listing can be found here:
Givenergy 9.5kWh Gen 2 Battery
If you are interested feel free to msg me
Thank you for the heads-up, I have messaged via eBay.
