Thanks for the update. We also enjoyed the level of solar in January (223.4kWh for us from a 5.4kw array). Quite a lot of grid import to handle heating (we've been heating exclusively with far infrared this winter). Travel wise 170 miles for us at 4.75kWh (the joy of ebikes).
Thanks for watching. There's quite a few people who are going full Far Infrared, we have a couple of panels in the garage and photo studio which works very well. Good generation figures for you for Jan, thanks for sharing.
@@johntisbury We've got some stats for far infrared (specifically contrasting with gas) if you are interested: ua-cam.com/play/PL4hBB421fBGr37fvzLcONhfAqfBYys9Fj.html The playlist covers background, stats for October/November and December/January.
Great update and good to see the Ripple is gaining more pennies! We are in the Kirk Hill and looking forward to the reduction in our bills. Well poor solar PV on our 7.56kWh E/W split gave 134.8kWh. With the demise of the TEP from Octopus, I am looking at moving to intelligent for 6 hours of lower cost energy! My ASHP has used around 3400kWh for the year as it was fitted last February. Kia E Niro used 309kWh for 962 miles completed. Total Electric consumption for January of 1936kWh for 5 bed home heated to 18c with a drop to 16c overnight, EV charging and home use. We have also had our non functioning cavity wall insulation removed and replaced with modern version. Apparently the old insulation was so poor it was as if none were fitted! Finally, I am in process of ordering hopefully another 4kWh Solar PV to be fitted to a large South facing wall, to help with winter ASHP and reduce non solar months to December and January, as well as providing spare in Summer to power the EV.
Thanks for watching and your detailed stats. Good news on the swapping of cavity wall, how did you find out that it was not functioning? Was that a heat loss survey / thermal imaging outcome? Did you consider solar thermal for the south facing wall as this would help with the heat pump over winter reducing its costs to run freeing up solar for EV charging.
@@johntisbury HI John, many years ago, I sought to get free cavity wall insulation but was told I already had some, so they could not help. After having years of a boiling hot bedroom in the summer and cold in the winter, I wanted to have it checked and when I finally managed to locate a company to do the work they stopped talking to me and i traced another, closer to me, from Sheffield area, Multi Therm insulations. They came to have a look and after drilling a few holes and looking with a camera probe, my cavity being about 8cm only had a slight covering on the far wall. Each hole revealed a similar position. Upon removal, they found many empty areas and the spray in foam from the 1970's had broken down and upon trying to pick it up, it collapsed into dust. I already have an Eddi, so fill my Powerwall, then Eddi then solar for my Zappi to my EV. With my existing 7.56kWh and13.5kWh powerwall, I managed just over 85% of night use and only sent 400kWh to the grid over the year. Unfortunately it was never quite enough to rely on for filling the EV. So using extra Solar PV, will give me spare in the summer to know I can charge my EV and assist in the winter when ASHP will be using more especially during the day.
Thanks for the detailed explanation of your cavity woes. Your logic makes perfect sense based on your needs and requirements, thanks for clarifying for me.
They did apologise and say that it should not have taken this long, but still, not great. The demand is high, but they don't seem to ramp up to meet the demand and manage their new enquiries or existing customers.
Thank you John. We had the first January with solar and the output was 186kwh, not impressive but better than December with 142kwh. Already 212kwh in February. Did the pigeons discover your arrays only recently? The gas tracker tariff looks much better than our flexible which is 10.31p/kWh. Will have a look into it
Thanks for watching, February has been rather good so far for us too. Glad to hear your generation is improving month by month. The Gas Tracker has recently been throttled back by Octopus as I believe many were moving across to it. The pigeons have only just moved into the area after having solar panels for 13 years with no issues. Bird protection wasn't a thing back then!
Where we are in north London I haven’t seen a pigeon ever and I didn’t opt for the mesh which was priced a good £850. About the gas tracker, Octopus is able to process fifty applications daily and they have a six month waiting list.
Let's hope the pigeons stay away from your area. I knew the Gas Tracker had become popular, but not that popular. Makes sense as it's much cheaper that the variable/flexible. 6 months though, crikey.
Have a look at this video here Ibrar. This is Project 1 which is now closed, they are on Project 3 now. Check out their website for more info, link in the description of the linked video. ua-cam.com/video/FsKv_mOYEkw/v-deo.html
Hi I’m new to this and with a Tesla on the driveway I’m interested in using Octopus/Powerwall to charge overnight and avoid peaktime energy costs. Am I correct in thinking based on your graphs right at the end, most of your savings in winter are down to charging the powerwall overnight and using it to provide power in the day? If so is it worth just getting a Powerwall installed even before having Solar installed?
Thanks for watching. In the UK there's a waiting list for new Powerwall installs around 8-12 months depending on which installer you choose. Everyone has gone mad buying solar and home storage batteries which has led to a longer lead time for stock. This may factor into your decision whether to go solar first or battery first. It maybe that you won't get either until later this year or even into next year. I would explain to your chosen installer of your longer term plans of solar and a battery as that may impact their approach to the DNO for approval/informing them of the instal. To answer your question, yes our winter savings are down to charging the Powerwall overnight on cheap rate in the Winter months and run off that during the day.
@@johntisbury thank you John. I found your helpful video from 2020 about the costs and benefits of Powerwall. I suppose the current high energy costs have made it a much more compelling purchase but a quick “back of a cigarette packet” calculation suggests a single Powerwall saving £3.37 a day based on 35p/unit peak versus charging at 10p/unit offpeak on Octopus with a 13.5Kwh Powerwall. Have I done that right? We have a large house, home office and kids and use 50Kw/h a day just on electric - bills are around £400 a month. Whenever I look at Solar or battery systems I’m unconvinced even now they would do much more than touch the sides for a very high install cost.
The cost to install solar and a home storage battery is certainly not cheap. The plus side though is that it will pay itself back, but will take time, even with today's high prices. I guess the main benefit is it gives you some energy independence and buffering from volatile pricing. Savings are always tricky to calculate on behalf of someone else as there's so many variables. The key takeaway is it's worth doing if you are in your forever home. If you are not, then the returns may not cover the installation costs. Your back of the fag packet cals is about right. This video of mine might be worth a watch if you've not already seen it: So you want solar and a home storage battery ua-cam.com/video/nei3eku_X5Q/v-deo.html
@@johntisbury thanks again. I learnt more about the realities of doing it from a couple of your videos than all the “information” I could find on Google.
I don’t know if I’ve missed this in previous videos, you have a Tesla Powerwall & the gateway, if I remember correctly, does this power your complete house if there’s a power cut, or only limited circuits , I’ve been told it can only run limited circuits but I would like to know if that’s correct, or am I being told lies. Hope you can clarify this for me. Thanks
Hi Peter, the answer is ‘it depends’. Not sure where in the world you are, the following example is from the UK. If you are single phase then the Gateway 2 will do whole house backup supplying 5kWh constant load. If you are 3 phase then it’s whatever is connected to one phase.
Thanks for the information. I live in Kent in the UK, I had PV fitted last July and ordered a Tesla Powerwall at the same time, with delivery in December, which I accepted but never arrived. Eventually in January I was told they can't supply the Powerwall and have offered other battery options, only to be told they will only power certain circuits, which is not what I expected, but they informed me that's what the Powerwall would have done anyway. I understand that really high demand items wouldn't work, but the whole house connected through the Powerwall. In your house, if there is a power cut, can you use all the circuits in your house, with the exception of your glass ovens.
It would seem that your installers are telling a tall tail in order for them to pass on an inferior battery. The Tesla website is very clear what it can and can't do for Home Backup: www.tesla.com/en_gb/support/energy/powerwall/learn/system-design The caveat is 'depending on your electrical set-up', as I mentioned previously in the UK a Powerwall will work differently in an installation with single phase over one with 3 phase. If you have 3 phase then the Powerwall will cover all the house in a power cut, up to 5kW load. We have the Gateway 1 (being early adopters). This gateway is now discontinued and it does not have a backup facility, only the Gateway 2 does. The Gateway 2 is supplied as standard now. The Gateway 2 will provide full house backup for a single phase installation. It is also important to understand the response time for the battery. The Powerwall is instant, turn on a load of 5kW in the house and the Powerwall will meet that in milliseconds with no grid pull. Other batteries take time to ramp up to supply a 5kW load, some even 20 seconds or more. Over time you will pull so much more from the grid. Not all home storage batteries are equal. Have a look at a video I did some time ago about solar panels and home storage batteries. Might help with some information. ua-cam.com/video/nei3eku_X5Q/v-deo.html
I'm having trouble with the installer, PV instatted in July 23, still not completed. It has to be completely removed, has rails, brackets, etc, and replace all the panel's. I have 18 in 3 arrays, as the fitter didn't cut the cable ties to the cables, yanked them till they snapped, as the PV sometimes trips my house electrics I have told them to take them to replace them with new panels or return my deposit and clear everything away, and repair my roof, were they've broken the roof tiles They've agreed to replace the panels to the ones I accept, it's just the battery. Someone is going to visit me regarding the battery options, but it'll be interesting to see there answer when I can prove the powerwall would run my complete house. Thanks for your help

Great update John sorry to hear it has taken 4 months to get solar sorted. Here in mid wales you can not even get installers to answer the phone.

Hi John, what software do you use to draw your excellent line diagram of your overall system?
It’s done with MS PowerPoint.
Can you share some more information about the turbine? Where did you buy it how was it was installed , output?
