Solar update - July 2024 - plus first Mixergy iHP stats

1540kWh generated in July for a net bill of -£154. Our export tariff started on 10/8/23 so 3 days to go to the 1 year anniversary; the annual bill to date is £13 so I’m on track for a net zero consumption bill, just !

So glad to see that our Mixergy iHP is already reducing your hot water energy consumption 🙂This data is invaluable for the team to see, thank you for sharing!

Looking forward to a full review of the iHP 👍👍👍

Nice one Tim, I be watching for the IHP presentation. So 5.1 kWp south facing array 6.5 kWh battery Now I have a full year of data I can see July in (cloudy )Central Scotland returned about 50 kWh less than last July at 574 kWh. Best day on July 31st at 35kWh, and my export paying £46

Good stats Tim. We generated 670.62kWh for July from our 15 panel ESE & NW array. Switched to Intelligent Go earlier this year which is working well for us. We charge the car, batteries & run appliances overnight & export most of what we generate during the day, less any house load. Negative Octopus bills for the last few months which is all good. Still got a gas boiler though. Good to hear that your iHP is up & running & performing well. I do like the iHP concept but I'm struggling to find a location to put one. Like you did our attached garage is the obvious place but it is completely rammed & would need a serious re-shuffle to shoehorn something of that size into it. More thought needed as part of my "delete gas" planning. 🤔

July is the middle of winter here in Adelaide, South Australia. Solar is getting better slowly. Now past the shortest day of the year. Generated 387 kwh from the 6.3kw North facing house system and 427 kwh from the 6.5 kw East/West shed system for a total 815 kwh.

Great results, we managed 808kWh from solar PV on 7.56 kWh E/W split. Consumed 982.7kWh with 511kWh exported. EV used 391.59kWh. Our Tesla Powerwall allowed a high 95+% night rate use!

Cheers Tim. Fingers crossed on the Givenergy EVSE integration with Octopus Intelligent Go. If they are looking for testers then I might be interested!

IHP COP might improve in winter strangely. The lower temp water entering the cylinder is easier to heat with lower flow temps (up to the temp it is now) which should be more efficient COP-wise, but of course will use more energy overall.

As long as you can perform a test charge and have a compatible charger (ohme or Zappi) you can get on intelligent Go. I don't have a compatible car but I managed to get on intelligent go. The extra hours cheap rate charging is well worth it in the winter to charge my 25kw battery.

Early feedback on your Mixergy iHP is interesting, similar consumption to my 9kW LG Therma V ASHP on hot water only, about 1.5kWh a day. I know its not all about the financial payback but I should think it’d take quite a while to recover the full purchase and installation cost vs using the immersion heater. Look forward to seeing your more detailed stats

Hi, I love the video's and have downloaded the spreadsheet, however I have no idea how to get the data from the inverter. Have you done a video in the past or can you do one to show the process. Many thanks, Dave

I do wish they’d put the battery in the middle of that flow diagram…
