Re: Does anyone have knowledge of laying concrete slabs?

I'd be tempted to pour it directly onto the hard clay ground. A car isn't that heavy and it doesn't look like you'd be able to get anything too big into that she'd. I would, however, put some steel into it. It makes it a lot stronger. For comparison the last shed floor I did is 125mm with 6mm steel ...

Re: Freezer minimum temperature

Some manufacturers specifically rate their freezers for use in outbuildings (so are rated to use to -15C).
From memory we bought Beko ones for that reason

Re: Limiting Export

Getting 3-phase is cheap and easy if you have 3-phase running past your house. If you're more rural and are at the end of a long single (or split) phase 11kV line with a ropey old single-phase transformer, then you're looking at the thick end of 5-figures. I'm sure if 3-phase was simple or cheap to...

Re: May 2022 Generation

Total generation: 380kwh

Generation per kwp: 95kwh

86% of PVGIS

Significantly lower generation than March and very few days in the last week of May where the max temperature reached 10C!

Re: Storage

I have wondered about the proposed PHS at Loch Kemp (although it seems to still just be an idea rather than something that is progressing), it is very, very close to about 0.5GW of wind turbines and only a couple of km from 100MW of hydro. For the cost of a few thousand meters of cable they could by...

Re: Storage

There is a segment of the industry that makes their money by planning renewable projects, getting all the permissions and then selling the project into someone else to actually do. ILI send to be one of these companies so don't expect them to actually construct anything. (RES does the same with wind...

Re: Reducing our carbon footprint...

In oil exploration, one of the most polluting industries in the world, every drillship I have worked on has run on diesel, largely because it is cleaner than heavy marine oil..... And cruise ships run on heavy oil? You would have thought that it's an industry that would want to protect its reputation.

Re: Bicrop planting win.

It's still done on the Machair ground in the Western isles, usually a mix of Machair oats and rye. The idea being that, in an area marginal for growing, if the weather doesn't suit one cereal then hopefully the other will be ok and famine can be avoided. Nowadays it is mostly baled as wholecrop sila...

Re: Solar Diverter

Thanks for those ideas folks. I think those means I will (starting with the simplest, cheapest options); 1) investigate why the immersion is not drawing the full 2kw. 2) investigate if the inverter has export limitation and see if Gareth's idea is possible as that could get me up to 3kw with only th...

I think you are probably right and my memory had failed me on that detail.
