Thanks all, reassuring enough. The lower output probably wouldn't be worth doing anything about at this stage, especially if it's been a bit of a bum year anyway

Could anyone who logs data, for a South facing array, look back through the last year's worth of data for me and compare to other years, Have been averaging 4000-4300kwh. This year as of today was 3875kwh. Hasn't been a noticeable significant drop off until this, the 10th, year. I suspect there must...

Do you need to move/replace the old panels? What is the gain? Space? Location? They'll be a bit more efficient for sure but that seems like it will be hard to recoup. If you're going the export limitation route with DNO anyway, you may as well tessalate the maximum kWp (within reason!) you can on th...

Having messed about with a couple iboosts and wiring in less orthadox ways, unless the load is below, say, 2.5kW, I would wire using only 16A plus rated stuff. Especially the output side. I don't know if it's the flavour of electricity they put out or the constant extended heavy load that can run on...

There's one down in Totnes. Doesnt look as big. Am presuming it's plugged into a generator.

If one were to try to add an under the radar array, export limiting it to not exceed the original MCS capacity is surely advisable. On the longest and sunniest days, starting with full batteries and being out of the house, I found it necessary to be discharging the batteries from quite early in the...

I'm wondering if Octopus would notice this care What do you guys think? These are interesting questions that remain unanswered. Either those who are doing it don't want to publish the fact online. Or no one is doing it here. Gut feeling is that they will have some level of checking. @15p, there is ...

Have to ask though, is a North facing array worth the expense? What's a back of the envelope payback calculation look like? It's a good question and I didn't include the expected generation, which is around 2.2MWh/yr. There are a few Youtubers recording data from their north facing arrays, and it s...

Who knows what checks octopus do? They could; -Monitor export and flag anything over stated capacity registered with MCS/DNO -Monitor usage and export intelligently and surmise that the profile smells fishy, compared with what's declared. -See a valid MCS certificate and make no more checks. To play...

Hi Gareth, don't forget charging losses. So you might want to drop the night rate battery charging from your calcs, as the margins are very tight, assuming something like 10% losses. Yea, there will be losses to factor in left right and centre. -Winter days where the inverters barely bother to wake...
