I took a slightly different approach. I looked for a rain free day during the hours of daylight, then looked to see if the next two days were rain free (left axis, blue diamond). If they were, I looked at the mean and standard deviation of the solar power, during the hours of daylight, in watts (right axis red square and purple cross) for the full 3 days. There is not a full years worth of data (got to drag some more out), but it shows a rise in mean power as summer approaches. The 'gap' in the data during July and August is not missing data, it is the rainy season down here, better known as school holidays. I have not done a proper correlation yet, truth is, it is late, and I can't think of an easy way to show it. But a quick visual scan shows more power during times of rain free days.

Can't agree with that. The Police should have been prosecuted for negligence and abandonment of duty.

They drive Saabs, if only they knew it is a Vauxhall in a special frock. They get their poloneck jumpers from Steve Jobs' bins, and glasses from SpecSavers. Pencils from Poundland and sketch books from The Works. Then add a few hundred percent markup.

There used to be a saying that the weather tomorrow will be within 20% of the weather today. You can take your pick of any aspect to measure and predict. For a laugh, over at the other place, I predicted the sunlight for a day, a year in advance. I just squeaked in, once standard error was taken into account. My first Masters was meant to be 'The stochastic nature of clouds on PV generation'. As usual for a Master's program, that idea was crushed. May still have the data, so could revisit it.

You only have to draw half of it in CAD, then mirror it. Just make sure you draw the top half, not the left hand side. Rotating it 90° anti-clock, it looks more phallic than gothic.

I went to the same school as Tony Martin. He was considered odd, but he was from Norfolk.

Dudley Moore, Francis Rossi (and his Dad's ice cream), Sarah Pascoe (though a Cornish name), A127 and A13. I still have a soft spot for the place, the mud at Old Leigh.

Just had a quick look at my usage for the 10th Sept. Mean of 243W, total 6.080 kWh It was washing day, so a bit higher than normal. Your 300W is pretty good considering that you run your water systems as well.

Were you charging the car as well? Or was it just a very dull day.

An old girlfriend of mine bought a Cornish Unit, got the local builder, who was an expert on them, to do some work. Everything was a surprise to him, he had never seen one like it before. Strange as most were identical copies. So maybe this is something to do with it, hard to get work done on them.

The marginal difference between the cost of lease cars is pretty low though. Not as if these people go out and buy them with earnings they have generated on the last few sales. They may have been getting the blinds from the same company. Reminds of this:

This may be worth a listen to understand things a bit more. https://www.bbc.co.uk/programmes/m00088mc

True, we overvalue diamonds and celebrities and undervalue clean water and social care.

That is more a reflection of his customers shallowness than any real, measurable, business methodology. If someone turned up in a £100k car and was selling an identical product to a man in a cheap suit and a wobbly Vectra, I would pick the one that was offering the best service. If you make business decisions based on emotion, it is time to retire.

Never looked into it too closely. There is evaporation losses, which are disproportionately high for and semi absorbent material, not that glass should be. May have to spend a few minutes looking it up. A friend of mine has a similar type house. She had a similar conversion done, may ask her what calculations were done. She did not have to worry about neighbours wall as her place is end of terrace.

I said I am a special case. Am not bitter, other may be. But are you capable of doing all the H&S, Food Standards and Employer paperwork on your own. Do you get, by law, inspected every 2 years and have those results in the public domain. And that is before TripAdvisor reviews.

It is those loses. I can't remember where the figures are published, but a few online calculators state it. I am not 100% sure that just the u-value of a window takes this into account. Here is one: https://insulationcart.com/knowledge/u-value-calculations/what-is-a-u-value-and-how-to-calculate-it/130

You can. I am a special case though as I moved down here for other reasons and only play at working. My background is very different from my current job. I work in catering, because it is a reliable income (I live in a seasonal holiday part of the country). The usual wage for a chef, down here, is around £18,000/year. Half the year is compressed into 3 months though. Other staff, are generally on minimum wage and zero hours contract. State benefits often pay a lot better than working. Why I have no problem with people on benefits. And they get to go surfing. To put things into perspective, a mate of mine works a an engineer in the renewable energy field (properly qualified and chartered) and earns less than me. He is not unusual. I don't work in the RE field any more, too many interns and 'professional' that know very little. As for 'spending 7 years' training. I spent that many too, not counting my apprenticeship in toolmaking.

You said it. But if a VT is earning around £12/hour, your staff will be earning less, say £10/hour. Which is what I said a mystic at the seaside is worth. Just for a laugh, cut one persons pay, and increase another, give it 6 months and see if the productivity has changed. Productivity does not correlate with pay very well.

That is just the steady state value. There are surface affects that will increase the losses. I think they are in the Building Regs. That is exactly the time I see spelling and grammar errors.
