The cost/savings/earnings breakdowns that I'm sure all installers still include, should also note that for every kWh "saved" by the iBoost, the household will be losing out on 5.5p (or whatever the going rate) that could have been earned by selling that kWh.We don't have iboost but certainly something to be considered as it's especially useful in the shoulder and winter months.Not the case for me, the similar device installed here is most useful in the summer and shoulder months, it's of very little use in winter.
If you are self consuming most anyway then paying more for what you buy in the winter just to reap a decent payout from export, may not make sense.
So to answer your point specifically, it would be a costly choice to go with a supplier costing more per kwh just to get a higher export rate.
You need to understand that this is not a one size fits all scenario , everyone's use is not the same.
I have "bought" 5mwh a year up until last year, and exported around 1.5mwh.

My understanding was that was not possible with the seg payment, clearly I was wrong. Mea culpa!
So its really only those of us who are on a fit and deemed export that will benefit from consuming all.West central Scotland

I understand the cost impact of having iboost. Just thought I would reduce use of gas if possible. Can always turn it off if it's really not worth it. Also grid may put limits in export sometime in future?
Regarding my final setup. I decided on 8.3Kw PV (JA 460x18) , 7.5 kw sofar inverter.
Comes around £6.5k including iboost and bird guard. Hope DNO approve it.2
