Will almost certainly involve scaffolding, removing the modules, fitting the micro inverters or 'smart controllers, then rewiring back to a new in inverter. SMA has a good, dual string MPPT built in, though, as you say, does depend on how the modules were originally wired. Getting 3 MWh per years, depending on your location, sounds pretty good. Have you run the numbers though PVGIS to see what it predicts? If your car does 40 MPG and you drive 8000 miles a year, improving it to 45 MPG saves about 1 MWh of energy.

Why not buy a cheap radial fan, tape it to roof of car. Wire it to a small travel kettle. Monitor volts and amps at different road speeds. Then you will see just how piss poor it will be.

I use the Envi model that has the optical sensor. Can you read the LED on the import meter and decide on its state what is happening? i.e if no flashing direct PV to battery storage, if permanently on, say for half second, divert PV to DHW.

So that is really where RB lost my pension, not on 'the turmoil of 9/11'. Bastard still, in my eyes, owes me £70k, plus 20 odd years of growth.

Didn't NTL do exactly the same, but with wires. There was a company that ran new data cables in Aylesbury in the 1990's. Then went bust. I assume the dark wires/fibre is still there.

Wrap a pipe around it and pump some water though. Slugs, squirrels and dogs burn well.

Not if 4 of them were on the same circuit. @Old Sparks spend an hour there taking 5 minute readings, then go back in the morning and see what has happened.

Because is is the only practical form of energy that is storable, transportable, relatively cheap and can be generated in a very low carbon dioxide (and other pollutants) manner.

Are two phases of the three used for E7? The billing details should show this, and the meter numbers.

I would think that most washing machines and dish washer could take water at 35°C. That would not be an unusually high temperature for Central Europe's taps.

Have to be low electrical energy users. That is about what I use in the winter excluding space heating and DHW. Currently using about 5 kWh a day.

One of my children's party tricks is to put my hand down my trousers and produce two hairs.

What is the rabbit up to? Not going to mention the prematurely aged self builder.

Was compulsory to do that in my office. Became a talking point.

Was not complaining, just that FM2015 seemed to know a fair bit about the different systems. Bit like Craig and windows

Not sure what sort of work you do at home. Guessing not film and video editing. Map of the world is good. I like the ones with lots of pink on them.

Mine did. Though it came back to haunt me about a decade later when I wanted proof of no claims. I had forgotten about the insurance scam I was a victim of, but the insurance companies had not. They did accept that at the time of the claim (by someone else) that my contact address was different from my permanent address. British Gas never understood this when I moved, or my bank. Both kept sending stuff to my old address. Specsavers have, for over 30 years, always managed to track me down, think they use the NHS data. I keep asking to be removed from their marketing lists.

Can get anti-thieving-slug spray now. Going try it on neighbours black cat.

@FM2015 I may have missed this in the past, but are you professionally involved in ICF?

I was thinking more along plinth heaters.

I prefer to use other's swimming pools.

An igloo has high mass, and, at 0°C, fantastic heat capacity. The conductivity is very good as well.

Thanks

I think it comes from people who never measure anything. False axiom as all that.
