I didn’t get in on the first one but have a deposit in for the second. I’ll need to time it right so I can present some big electricity bills :). The main stumbling block is i would need to move to Octopus and we can’t get a smart meter due to lack of signal for both smets 1 & 2. The usual tariff is no good for us due to cost.

I’ll certainly post some photos as I go. The shed only went up yesterday 🤪 I’m just approaching companies now. I’ve been data gathering the last few years so I can spreadsheet different combinations. There is certainly a law of diminishing returns. Going from 6 to 8 pylon techs has the same payback period with the setup. Which is under the worked 10 year useful lifespan. Hopefully I’ll get more and by then there might be some wonderful new tech that doesn’t cost a fortune. I dream of being able to fill a tank with something during the summer months to run a generator in the winter.

It will be interesting to see how it plays out, I'm just hoping to get across that nobody ever wished they put less PV on. If he goes large now it will cost less at the beginning on average and he'll hit the ground running.
Exactly, put in as much as can afford to/allowed to.

Even at 3 phase that would be over 250A per phase I think.

Maybe some big batteries and a public EV charging point to recoup some further outlay during the summer tourist season :D

The guy's energy needs seem quite modest. He's very unhappy about spending c. £2.2k a year on energy. There seems to be little point suggesting a £30k solar installation!

I'd suggest 12kWp of solar, split into: c. 4kWp feeding directly to a 3.6kW G98 inverter/charger and c. 8kWp fed into charge controller with a 19.8kWh battery stack.

Here is my shopping list:
  • 31 x 385W panels (@ £118+VAT ea) = £4,310
  • Victron 150/100 Charge controller = £770
  • Solis 3.6kW Hybrid Inverter/charger = £1,120
  • 8x Pylontech US2000C )@ £682.91+VAT ea) = £6,390
  • TOTAL = £12,590
(Obviously not including mount or installation)

I'd also suggest a large "Ecconomy 7" DHW cylinder and solar diverter as well as a 5kW air-to-air heat pump. He'd still need some auxiliary heating for the very darkest months, be that his existing Oil system or a WBS. But he'd have more power than he could possibly use for 9 months of the year.

How would (or just "Would") an outgoing agile export tariff alter your comment?
A
2.0 kW/4.62 MWh pa in Ripples, 4.5 kWp W-facing pv, 9.5 kWh Givenergy batt
30 solar thermal tubes, 2MWh pa in Stockport, plus Congleton and Kinlochbervie Hydros,

A
The prospect of earning money by exporting power would result in going for a bigger inverter/charger in exchange for the charge controller. Does he have 3-phase? Would he need a G99 application? The brief was to reduce ("eliminate") energy costs, does he want to invest in exchange for a financial return?

That Solis inverter will take up to 7kW of panels so I would load it up fully, with the rest on a smaller charge controller to the batteries.

With regards to export tariff I would not touch the Agile one as that limits what import tariff you can have but the fixed export one would be ok, still get 5.5p / kWh.

And adding Ripple's next wind farm is worth adding too, for charging the batteries on cheap rate in winter.

PS - Andy, your now on my Ripple WT2 secret members list. :lol:
