Fit optimisers on each module, should not affect the Fits. As you have 3 Phase, you can add extra to the other phases. Not sure how that will work with your phase diversity though, that is up to you how you design the loads.

Cheap way of publishing to the WWW. No need to pay for a service, and security is built in.

As we enter, what is traditionally the coldest month down here, and because I like trying out simple changes to see what happens. I have shifted my E7 heating window from 3 AM to 7 AM (GMT) to 4 AM to 7 AM (GMT). This is party because I noticed that all the heating had happened before I was out of bed, and party to try and use low CO2 generation, which is what the ultimate goal of us all should be.. So as usual, a couple of charts to show the difference. Early days yet, And CO2 charts.

However, if a house is orientated to max solar gain and filled with insulation (like mine) it does not matter what heating or temp it is set at it is still more efficient. Really down to what you compare it against. With no official figures for energy usage, i.e. 5W/m2.person or whatever, it is impossible to separate fact from fiction.

No advice from me at all about what to do, other than check your house insurance and see if it cover legal disputes with neighbour. Maybe this should be merged in with the below threads.

I am always amazed how cheap carpet fitters are. The collect the carpet, carry it into the house, wiggling though doorways and up stairs. Rolling it out, cut it to shape, do the steps, and anything else that needs doing. Tidy up, take the rubbish away, and only ask for 50 quid or so. You won't make any saving on the fitting, and you will possibly end up with a badly fitted carpet, especially if working on your own.

It isn't. It may be better than other 'forms', but it is not the most thermally efficient. You need to understand Mathematical Topology to realise that stretching, rotating, translating and twisting all affect the physical properties differently, often disproportionally. Is it part of the Planning Departments remit to deal with energy efficiency, or has that be palmed off to another department. The problem with designing a low energy home is that the next owner may disregard the installed technology and design principles and fit a low efficiency heating system and tumble dry clothes, a sock at a time.

Yep, that special coating of sea salt, seagull shit and wood burner soot. Back to the original point about a Victorian terrace over heating, they are generally thin and deep, so the ratio of window area to volume is all wrong. End terrace with a south facing side may give problems, the ratio is all right for over heating. When we had the server heat warning down here year before last, my house did get hot, and I did take tin foil to my window frames. This dropped the room temperature about 10°C, it then was just a little higher than the external air temperature. But that was a extreme case, and we had nothing like the temperatures recorded up country. If I have left the down stairs windows open all the time, it would have probably have been better, but the heroine dealer across the road would probably have stolen my furniture to put on his fire (thinking about it, not seen him for a few weeks).

The ones that have been in service for a few years, initially had problems, but I think they dropped the pressure, which rather defeated the object, to make them more reliable. Probably why they have not been taken up in the domestic market, don't want people fiddling with the controls to get an extra 5°C out of them. The easy way to boost performance is to make them larger, or fit two separate units.

Different type of glass chemistry, and thickness. I did make up a spreadsheet many years ago that calculated it, think it is on an old backup disk somewhere. So may have to rewrite one, especially as I am trying to move from Excel to LibreOffice Calc. Even Excel 200 is so much better tan the last but one version of Calc, just waiting for the Portable Apps people to get the updates sorted for my version.

Mine is still chugging along very reliable. view-source:http://7apbx6oiuuxtkegq7idqbwgwcjzbjvmwdqcddnesnptjkvd7qkvhkxyd.onion/data/1wire-4-2-2023.html I must get around to charging up my old solar powered 5V battery banks, I am sure I can find the box they have been hiding in for the last 5 years.

And the Ideal Gas Laws are rewritten in an Alternative Fact manner, I think we will be hard pushed to find a refrigerant gas batter than CO2 for the foreseeable future. One problem with heat pumps is that they cannot contain too much flammable fluid if they are inside the house. From https://en.wikipedia.org/wiki/Ideal_gas_law where: is the absolute pressure of the gas, is the volume of the gas, is the amount of substance of gas (also known as number of moles), is the ideal, or universal, gas constant, equal to the product of the Boltzmann constant and the Avogadro constant, B is the Boltzmann constant, is the Avogadro constant, is the absolute temperature of the gas, is the number of particles (usually atoms or molecules) of the gas.

Then multiply by the transmission and reflection factors. I think part of the problem is that sitting in a room with a sunbeam on you makes you, as opposed to the room, feel warm. I am tempted to one of my bigger analyses on the effects of solar gain on my house. Just need to collect more historical weather data.

I have had Victorian Terraces, solar gain was never a problem. Even in my current terrace, solar gain, with the occasionally most powerful sunlight in the country, is not a problem. Are you sure you are not mixing up solar gain with increased external air temperature?

There will be a small drop in performance, but not enough to worry about. A 5.6 kWp system, can occasionally, produce more power. All down to how the modules are tested.

That is where the 'testing for data collection" comes in.

Newton Law of Cooling can be modified to become a heating curve. Play about with this to get a feel what happens when heating something. Heating Power Curves To Radian.xlsx

I suspect people change their vehicles to a newer model more often than they change wood burners. We already have legislation to reduce the number of ICE cars, and many cities have pro actively banned the worse polluting vehicles from cities centres. I drove, in my old EURO4 Diesel past the Hayle estuary the other day. There was a haze over it caused by wood smoke. There is probably less than 100 houses next to the bank, and even less higher up. If 10% had the stoves going, it showed how bad things are. And that is just the visible smoke, can't see the fine particulates, but they are there.

A picture of it may be useful, or any make and serial number. There is probably a button or two that can be used to cycle though the readings.

Will they be wearing yellow vests, and carrying pitchforks. When it is 34°C in the summer, heating 200 lt of water by 25°C is not going to take much energy, or time. You can limit the rate that it heats up to keep the stress off the system.

Will that be about ten to 6 on the 31 January 1606.

Would I (expletive deleted). We all want to know whose missus trumps the loudest, and highest pitch.

Two things, it is not just smoke that is the problem. Probably illegal to fit one that is not approved for the zone it is in. Easier to just not bother, they will, in time, be banned anyway.

Panels can deliver more than the stated rating, it is only rated at one light level and one temperature, so is that p to 14 kW? Was that limited by the inverter? Seems about the right generation, but if it is exporting on an unused phase, your imports will not be affected. Obligatory kW and kWh.
