Re: SEG and tax implications

I guess that is where the maximum 120% of consumption value used by Ripple comes from. What is then unclear is what is the tax situation when a homeowner has rooftop solar PV and a Ripple investment? But as previously mentioned, how is the solar PV generation value collected? It was under FIT, but n...

Re: Part ownership of a Ripple Wind Turbine, fancy it?

So the first batch of the DW solar panels are now mounted on their frames, with a gold standard array checked and available for comparison when completing the rest. https://i.postimg.cc/67MhNw0S/DW-1st-array-Screenshot-2024-11-15-144005.jpg The sequence of works as described by Ripple is to complete...

Re: Storage Heaters, Tariffs & Control

I am with Octopus on an E7 tariff, with a SMET2 meter that uses 2 consumption registers and stores the tariff rates for reporting on the IHDisplay. It is not quite as cheap as the EV specific tariffs but I find it reliable to be able to align my device timers with the 7 hour cheap rate period and ca...

Re: October generation 2024

East/West system - 6.56 kWp October PVGIS (11% loss) = 272 kWh 2023 = 249 kWh (92% PVGIS) 2024 = 222 kWh (82% PVGIS). Met Office - Midlands - Sunshine Hours 2023 = 92 h (94% of recent average) 2024 = 97 h (100% of recent average) So more sunshine hours according to the Met Office and lower gen in 20...

Re: ASHP & triple glazing

13 sealed airpockets in the lower section & 11 in the upper section.Apparently, this profile was developed for a U spec that was later rolled back to a lesser efficiency qualification by govt. Lots of pockets for insulation performance, but what happens with trickle vents and water drainage? I ...

Archimedes Screw

I came across an example today and saw it in action from a distance at Bainbridge in Wensleydale, North Yorkshire. After some online research it turns out it is a 45 kW unit and has been running for many years. https://en.wikipedia.org/wiki/River_Bain_Hydro Has anyone come across any of these elsewh...

Re: THe end of Ratcliffe-on-Soar

The mounds of coal are shrinking in size, almost all gone now.

Re: Part ownership of a Ripple Wind Turbine, fancy it?

The KH video includes a close up of the switchgear cabins with SF6 warning labels on the outside. Not very green when SF6 has a greenhouse gas index of around 23000 x that of CO2 and is due to be banned in new switchgear by the EU in 2026. There are SF6-free alternatives on the market already so why...

Re: Aiko comet panels.

Have you considered the match between the overall panel string voltage and current against the capabilities of the inverter? The inverter startup voltage needs to be achieved as early as possible in the day even with shading of some of the panels. My gable wall panels perform well in direct sunlight...
