Hi @JNeve, brilliant, that saves you having to take manual readings twice a day (as I was doing for 13 years before my smart meter arrived!).

 

That’s by far the biggest energy-saving step, I find, ensuring your OVO account (or other energy provider?) is set to receive half-hourly meter readings.  That way, every few days, you can accurately monitor your usage (gas and electricity, but mainly electricity). 
 

We are a retired couple living in a smallish mid-terrace, so we can be flexible around our energy consumption, in a way that many households cannot be. There are loads of good tips in this forum from various folk on various thread, definitely worth a good explore! For example, my wife and I routinely use a smallish rechargeable battery-power vacuum cleaner and reserve the big mains one for very, very occasional use.  Loads of tips on here from different users, so you’ll have fun exploring around! If you have specific queries as a result of digging around, or indeed at any time, I’ll be delighted to respond as best I can, and there are plenty of folk on here who are infinitely better qualified than I am who are very helpful. 
 

We got PV panels ten years ago, and if that’s something that might be on your mind, I have ten years of PV data for our small set-up here in Sunderland (not the sunniest spot in the UK by any stretch!), and it’s not always easy to find actual solar panel data from an actual user over such a long period from an actual smallish NE terraced house! So let me know if that sounds relevant to you?

 

Last Autumn we took a bit of a financial gamble and I obtained a small LiFePo4 battery (24 volt 100 AH, equates roughly to 2.5 kWh capacity, though, as with any battery, not all of that is available) and a small inverter, which recharges during the day, and at night for 17 hours solid powers the entire house (small, of course, but it does have a ‘fridge/freezer, small chest freezer and all the usual background stuff of mains alarms, landline handsets, router etc. - plus led TV and lighting before we go to bed) from 1600 hrs to 0900 hrs. During the winter months in daylight (“daylight”!!) the PV panels only provide about 1kWh (sometimes, on the very worst and darkest days they might provide nothing), so we need to buy between 1 and 1.5 kWh daily on average during Nov, Dec, and Jan, the hardest months with the shortest days with the sun (when it’s there!) at its lowest angle. Before the battery, in the winter months we bought around 1kWh during the nighttime alone between 2200 and 0800. So even a small battery like ours (most people talk about battery storage of minimum 5 kWh) makes a big difference. 

Lots of other smaller outlays which can eventually have a huge impact, such as getting a plug-in energy monitor to gauge the consumption of your various appliances. The smart meter IHD is brilliant, but there is that half-hour or so time lag.  

And this brings me to my final point for the moment (hope you’re wading through all this OK! Apologies for the wordiness!): Previously we’ve always concentrated on daylight versus nighttime consumption and on being really disciplined at all times on what we use, when we use it, and on replacing old kit with newer kit when we can afford it. But since the OVO Power Move initiative we additionally now factor in our Peak Hours consumption and reduce it as much as we possibly can, which can earn you an extra £15 in your account every month. That’s not a fortune, but it makes a nice contribution: in effect it’s getting your entire electricity standing charge for the month paid off, or, it’s the equivalent of around 50kWh of free electricity.  That’s about a week’s worth of electricity for an average household. Plus, being extra rigorous with Peak Hours consumption has raised our awareness enormously and is good for all our community.

 

All the very best of luck to you, let us know what occurs!

Thanks Walt for that glowing report on the Fronius !! Yes my installer pointed out the vat thing, I’m sure now that lots of battery storage will make sense for my house setup with the heat pump. I’m getting pv but although the roof will fit 22 panels I think I’m only going to get 11 and spend the money on more batteries. I will get everything together but I’m waiting for my main fuse to be upgraded from 60 to 100 Amps - unfortunately overlooked since I had the ev charger installed 3.5 yrs ago then the heat pump 2.5 yrs ago. It’s a bit annoying that I didn’t get it done before but hey ho, I’d rather wait and keep it all safe.

Great stuff @juliamc, sounds like a thoroughly organised setup you have there!

 

You’re absolutely right, Julia, about the extra battery capacity, unless you’re consuming a heap of electricity during daylight hours, 11 panels (each one probably around 350 Watts nowadays? 10 years ago, mine could only be 200 Watts each! A lot more bang for your buck now!) is more than enough to keep household consumption and batteries happy. As you so rightly intimate, the more battery capacity (within reason!) the better, the minimum nowadays seems to be 5kWh and a lot of folk now aim for anything between 10 and 20, which I guess is what you’ll be looking at?  You opting for greater battery capacity means that switching on your oven and, say, a washing machine, plus keeping all the usual backup stuff going, won’t be a problem when you've got plenty of nice battery backup waiting to be used. Smaller battery capacity would have meant you’d have to call on the grid a lot more frequently to top things up whenever you switched on the really big hitter items. 

 

Looking forward to hearing about it when it’s all up and running, and of course the EV adds another highly desirable, and extremely interesting, green energy dimension to your setup…

This shows how much electricity the heat pump has used since Jan 2022 and as you can see I need stacks of power in the darkest months (so to speak!). The pv will only come into its own spring and autumn to keep the hp going, then in summer we’ll have to use the car loads to make use of the solar rather than sell to back to the grid.😎

Yes, it’ll be fascinating balancing across all our unpredictable seasons your household loads using the grid’s supply (hopefully vastly reduced!) and your battery/PV supply, plus of course, potentially in the future, an EV supply (although that would require being able to leave the car plugged in virtually all the time it’s home. But that’s one for the future!).

 

I see what you mean about the HP consumption, and why you want a PV/battery setup that’s responsive to battery levels; I have little doubt that an up-to-date system like yours will fully integrate your household’s electricity supply and demand.  It’ll be nice to see those seasonal peaks smoothed out! 


Good luck…and do let us know….

Possibly, or just someone who forgot to write a full post before hitting send.

At least it’s not a spammer trying to flog junk - otherwise I’d have blasted it into oblivion by now

Could be an incomplete entry. My phone rebooted part way though a DM entry and I had to go back in, delete it and start again

 

Benefit of the doubt time then although the Blastoise186 Blaster has legendary status. Doesn't even leave a smoking ruin by all accounts.
