After spending a bit of time looking at the hikes in energy bills, my current go tariff vs this Septembers (pre October rise) then considering the October rise even with all my solar and batteries my average bill is going to jump a lot. Example December 2021 I used 505kw from the grid, my worst month. Last year worked out £101, this year it will be £189 (if usage is identical), December 2023 will be £265 unless something changes. I have not even factored in the new EV.

So GivEnergy, how about a small wind turbine that can sit on top of a house? Something than can generate 200w - 500w+ is that possible? If not the turbine itself how about the inverter for it that can integrate with the rest of the GE eco system?

I am just thinking that home wind generation is the next logical step. Something small that doesn't need planning permission but takes up the back ground device usage.

I'd also love something like this but there doesn't seem to be an affordable and viable solution at the moment so have decided to invest with Ripple wind farms.

I have considered this myself. Something around the 1kw region would cover normal daytime energy consumption in the house even over winter leaving only high-demand periods. I believe there are some issues with having multiple airflow-based energy systems installed at the same time that make having, say, a turbine and an ASHP slightly more complex but probably nothing impossible to overcome.
There are also regulatory requirements for spacing inside the property line etc, and potentially noise issues (though something that small should be possible to keep pretty quiet).

Agreed, I would too be interested in something that could go on either a pole, or chimney. 1kwp would be plenty to cover background. If the price was low enough to make it viable return in say 5 years.

judgepd Do you have a referral link? I see they give £25 credit, I was about to sign up to that too.

#7 THALL

judgepd I am now reserved for the next project. How much do I need to spend for you to get a credit? When I first saw Ripple it was £250 but on my account it says new referrals need to spend £1000!

Yes, it does say that it's £1000 now on my page too...get your cheque book out for me!

#9 THALL

judgepd If I invested £1025 it would cover 95% of my annual usage....... So nooooo sorry. I was looking at £500 - £600 investment. 1000kw per year ideally.

There is a few 'marine' types out there at reasonable prices, which can charge 12/24/48v outputs to existing PV/Hybrid setups, using smaller voltage controllers and load diverters if batteries are full etc.
Its not a bad shout actually but how would you integrate with GE equipment, unless a 'official' GE voltage controller goes in between.
If you goto your portal login screen, there is a wind turbine there, and also a water wheel, signs of things to come?
Who's not actually on a water meter? 😆

THALL I went for 500W to start with then saw them tweeting and got a bit carried away and added another 325W so my predicted annual generation is 2,619 kWh. I figured that the cost of electricity is only going one way so the savings are likely to be better than they have initially predicted.

DeanoC75 we haven’t a water meter. Probably will get one when the kids leave home but as it stands we are probably better off without one. But I actually don’t know for sure.

It’s ages since I looked into wind turbines for home - do they still need a dump load to stop them freewheeling/over speed if the load isn’t there/battery full?

If so this does make them slightly harder although perhaps my current setup with the PV string DC-DC converter could be a route to connect one in without risking a GE inverter as a test? Would be a bit heavy on losses though.

Would just export to grid

#15 THALL

judgepd I wont know exactly how much it will cost until project 3 starts but looks like I need to buy 640watts generation to give me 1000kw pa. So half of what my home draws from the grid. This seems like a good idea vs a turbine at home?

#16 GrahamShaul

judgepd I have no regrets on the installation of our GE system as it has made a very positive impact to reducing my running costs and ensuring that my energy usgage is greener. But my usable roof area is full and to hedge against future rises the Ripple Energy project just makes sense. My investment is in Kirk Farm and a reservation for allocation in the next project is in place. Seems a decent return for 25 years of electricty generation which is something that can move with you when you move house. At Kirk Farm our purchase was 0.647 kw which is projected to generate 2054 kWh annually.

Just looked at Ripple energy and to be a complete noob how does this interact with being on Octopus? I'd be very interested in investing in it as well.

#18 judgepd

Very simply you get a credit on your Octopus electricity account based on how much your share of the wind farm generated that month.

Thanks for the nice and simple explanation 😀 2500kwh per year would bring my solar + wind generation to a bit over our typical yearly mains usage, not bad for probably about the same cost as the scaffolding required to install a micro turbine, and no pi$$ing off the neighbours!
