For any latitude there will be an optimal angle that can collect the greatest amount of incidental light (direct beam) over a year. This does not equate to maximum power. Fitting brackets may marginally improve the total energy collected, this is called insolation, but may, if it causes some shading to other modules, or reduces the amount of time the module can face the sun, cause an overall decrease in energy. There is a meme that we should be fitting solar panels to all roofs before we build solar farms on agricultural land. This often touted nonsense shows a lack of understand of basic geometry, economics and engineering practice. Probably why the solar industry does not respond. Hardly worth the effort while they are installing PV at £45/MWh.

Bill Gates, Steve Jobs (if we was alive), and Tim Berners-Lee are all pensioners. C was started in the early 1970s, Python in the 1980s, Java, mid 1990s. Not exactly new any of it/them.

You will have to compare the m2 prices of the different system. Much of it does depend on how much you can get PV roof trays for, seems they can vary is price by a factor of 3 if you are not careful. Have a search here for GSE stuff. There may be cheaper suppliers.

Yes I do. I remember to turn things off when not needed.

Not or, as some becomes roots and leaves, of which some will rot to become soil, some CO2. What is burned becomes a mixture of water vapour, CO, CO2, NOX ect. The problem is that it can take decades for a tree to grow, but only a few hours, at best, to be released back into the atmosphere.

It is a standard E7 cylinder, so almost at the base. There is a secondary element at the top, but that was not used. Since I collected that data, I have changed the timings so that rather than heat at the beginning of the E7 window, it heats at the end of it. Mainly did that because for a couple of hours it was loosing heat to the house, and as I like a bath in the morning (decided I actually dislike showers and only use them to get work grub off) I wait till the water stops heating, then draw off a bath full, then they cylinder is at a lower temperature, so less losses. I really should start to monitor it again, maybe with it's own energy monitor as the kWh trace included all usage, so fridge, kettle (I am a very early riser) washing machine etc.

A good stir to get us going today! I shall say nothing, only because I am reading this week's scientific, as opposed to opinion based, comic.

Not trying to be clever or anything, just make sure I was not totally off track when I suggested this. I did not add any detail as I am basically a lazy bastard, and there are others that are much better at calculating this.

Here is what happens to my 200lt, E7 cylinder.

Repeat the experiment 20 times. Then run a chi square and a student T test on the results. I suspect the it is a combination of turbulence in the cylinder and thermometer/element/thermostat position.

Same problem going on here. I like the ''sagulator"

Had some sun today, then back to clouds.

Good spot, building sites are dusty

Yes, allowed to rummage in my trousers without getting shouted at as well.

(expletive deleted)ing right, repotted my Black Aeonium Zwartkop without any grief today.

First things first. Get him to take meter readings and update his account, if he is on direct debit, the £200/month may be just bad estimating. Then get him to read the meter every morning for a week. to see what is actually happening. It is quite possibly the legionella/disinfecting heater coming on and just gobbling up juice. Make sure that any immersion heater to the cylinder is off.

Very alone. There is not enough room to bury a body in that sad excuse for a garden.

Is his water heated by the ASPH?? My DHW bills is around 3 kWh/day for just me. That costs me 45p/day on E7, but if I had a heat pump, on a standard rate electricity, about 35p.

Because there is the wholesale market and the retail market. You would not expect Tesco to buy your home grown runner beans off you at the retail price. It is really the price of export you have a gripe with, as do I.

Unless you are paying for it.

How I forgot to get some milk last week.

This is the ideal time to test. @Wayne88 Make up so rods and bang them into some oak, let's see what happens.

Decimal place rounding on the Temperature HI. Ambient and OAT.

So that makes 3 of us anonymous. Why they galvanise it. Well they do for boat anchors. Make a load of spares and change them if a problem. Could always you oak dowels, like the traditionalist use.

Not sure why not structurally, @Gus Potter can answer that better. Some grades of stainless steel do not like to be in an oxygen deprived environment, why they are not used much in subsea environments, or rock climbing. I can't remember which grade it is though. This may help. https://www.cruisingworld.com/how/beware-stainless-steel-corrosion/ https://www.manufacturingtomorrow.com/news/2020/01/16/stainless-steel-best-option-for-corrosive-environments/14630/ Not many toolmakers left working. I did my apprenticeship in toolmaking, now most people under 50 do not have a clue what one is.
