Lol - the disease becomes less prevalent the longer you have them!Joined this cross fit style cult today. Thanks to @Mark Irwin and his many posts here went with KB. Very happy with the install- no batteries but 6kw on the roof and looking forward to boring the world for the next 10 years waxing lyrical about payback and how hot my hot water is.
Sun is shining one minute and not next, so one can't turn on an item using power with the exception of immersion heater with iboost and be sure only to use solar power. My heat pump tumble dryer runs for hours.It can work really well but there is a long return on investment especially now that the high feed in tariff is not available
Any good company quoting you should be able to supply you with data from around your area on generation averages etc
You can then compare to your electricity bills and typical usage patterns
Just as an example though, I bought a house with solar panels already in place and the high feed in tariff rates. They took almost exactly 10 years for the feed in tariff to cover install costs. Now they were installed at a time where the tariff was higher but so were the install costs so I expect it may be similar timeframe but that didn’t include a battery
It’s harder for me to factor in the electricity savings into that return as I didn’t live here for the first 7 years but for us it’s probably saving us £30/month as we also use it to heat hot water through an immersion
It all depends on how much electric you use. I use a lot of electric and have a 14.4 kwh battery that still runs out around 9 or 10 pm at this time of year even if it is sunny but that only leaves me 3 or 4 hours before cheap rate starts. I charge battery and EV overnight on E7. Everyone's circumstances are different and you need a set up that works for you.Sun is shining one minute and not next, so one can't turn on an item using power with the exception of immersion heater with iboost and be sure only to use solar power.

So one needs a battery to bridge the non solar production gaps. But does it need to last over night?
Some days I do export, seems around every other day on average, but not that much, and a second battery will cost £1,100 so seems unlikely I would get enough from the extra 15p a unit I get if I use if rather than export it.
However at the moment the battery has stopped working, so it may need replacing, so could if that's the case go for a larger one. Hense the question, is 3.2 kWh enough?
How the heck do I fix this. Constantly get these readings. Everyone is in bed from 10pm til 7am

Do you have solar batteries charging? Graph profile looks a bit too uniform to be accurate though.How the heck do I fix this. Constantly get these readings. Everyone is in bed from 10pm til 7am

I am getting phantom readings like this. Have the installer returning to investigate, although by this stage I know my way around the Eddi and Zappi menus so resisting the temptation to have a go myself and let them sort.How the heck do I fix this.

I’m not sure. I’m going to have to monitor the electric meter and see.Does the energy information from your supplier say the same? Do you have a smart meter?
If you can check this then you will know if it is real or if it’s something wrong with the install of the current measurement equipment
All approx's from spring this year:
2kw - solar array - £2800
3kw - solar array - £3800
4kw - solar array - £4800
Add a 5kw battery +£3000
The solar array included the cost of a hybrid inverter needed for a battery. If you don't want a battery take approx £600 of the array price as a standard inverter is cheaper.
"A fantastic option, if you have an immersion or buffer tank, is the myenergi eddi. This eco smart energy product will divert excess energy from your Solarwatt Panels to heat your water for free, increasing the efficiency of your home even more! At an additional cost of £500 + VAT this is an amazing extra!"Beginning to start researching various set ups. I like the idea of using solar to charge batteries and heat the water. We don't currently have any EVs, but I imagine it's only a couple of years away. What's the ballpark all-in cost for a load of panels, batteries and the smart monitoring / solar diverter gubbins for the immersion heater?
That's the way I work it. Today for example is very dull so house running partly on solar and partly on batteries that were charged overnight.If you typically use reasonable quantities of kWH in a day then fill your battery(ies) with cheap E7 electrons at night and let them piddle through the house during the day.
I'm about to swap my Solis over to do that for a few months as the sun is setting in the SW now and my W facing panels aren't picking up many rays.
Yeah, mine only did 3.49Kwh today although monthly total is 83.3 Kwh. Thought it would have done more with the early sun before haziness but it is low in the sky and solar activity limited.I fully appreciate its winter, and days are short on sunshine, but does this seem like a normal amount of generation?
Ignore £.

That's ok. Felt it was maybe under powered but I know you always get good ratings.Yeah, mine only did 3.49Kwh today although monthly total is 83.3 Kwh. Thought it would have done more with the early sun before haziness but it is low in the sky and solar activity limited.
