Wow that's a great price! You could go into the solar business with that...

We're supposed to be able to generate nearly 7000kWh a year and we only use 4500kWh for the house. So, best case scenario, we should be able to save 4500x £0.35 (our non off peak rate) = £1575 AND sell back 2500 at whenever it is best but e.g. £0.24 = £600. So that's quite a lot of saving / revenue in a year.

I still need to charge the car, but if I can get that to do it when the grid price is cheapest e.g. less than £0.10 / kWh, then that that's only £250 a year "cost", or less if I charge for free at Tesco stores or office etc.

It's a combination of generating from the panels, but also helping the grid to smooth out the load. It's not so much "selling" as trading. :-) G

There's still a daily standing charge of £0.45 so that's another £160 a year that you can't dodge, for the running of the service. :-) G

24p sounds great !! Why would you sign up to the SEG at 4p when you can get a fix at 15p ? How long is the fix for ?

You need to get your solar set up certified and everything and you are also committing to doing it with one supplier. But yes, it's a fix for a year.

I'm going to go with the Agile tariff though. I think we have enough flexibility with our car and our house usage that we can export at times of greatest demand and minimize consumption at peak times too. :-) G

Not sure if this will format, but that 24p at midday wasn't an anomaly. It goes much higher! :-) G

Did you say you can "buy" from them at 10p overnight ?
So could you charge up your battery overnight at 10p a unit and sell it back to them at peak hours at 40p per unit ?
Or is it not as simple as that ?

Ah, no, well spotted. The 7.5p overnight OR the follow the market not both! But yes, you can power up at 19p overnight and sell back at 42p during the day. They still make a profit on it. You are helping to smooth out the uneven load and hence reducing over supply and over generation. This should be good for environment, yes?

Need to configure the software though, at moment, I don't think the car knows about "solar" (though the charger software says it should). But still all good. Just tweaks. :-) G

Got something to say?

Hi
I've seen environment (whether emissions, power, climate change, access to countryside, whatever you think of as "environment") discussed in various threads: Politics (obviously), the Electric Car thread fetcheveryone.com/forum/electric-car-anyone-61481/ , run free's excellent "Competitive Running and Keeping The Environment Clean" fetcheveryone.com/forum/running-competitively-keeping-our-environment-clean-60907/ my own Greta Thunberg thread fetcheveryone.com/forum/greta-thunberg---jfk-for-the-climate-generation-61044/ etc. but I haven't seen a general one.

So here it is. For those interested in the science, the politics, the action for (and I'll state that for me, this is mostly pro-environment, anti-emissions, anti-pollution etc.) and the hope for the future of our planet.
