That is quite interesting. I live in a row of 6 houses, all electric. Assuming my neighbours all use the heating/DHW in a similar fashion to me i.e. E7. Then we can all easily be pulling an 8 kW load at night for a few hours. During the day this will drop to a couple of hundred watts, with spikes of a couple to three kW each house. I would have thought there would be no need to upgrade where I am Trouble is, hard to get even 3 kWp on the small roofs, so technically not a problem. But it makes me wonder about some of the larger, newer developments on the North Cornish Coast that are off the gas grid.

Yes, it take parts of randomness and chaos, drizzles them with new means of old words, then claims to be the answer.

I had the great pleasure of showing David Elliot around my university back in 2006. He tells interesting stories about nuclear power decision making in government.

Send that in for the SE side, the electrical certificate, the inverter certificate of conformity and the agreement with the DNO. Can't think you would need anything else. But just incase, list the mounting system components and manufacturers.

Oil hit £94/b So that will be 6p/kWh Considering about half is turned into heating/transport fuel, that isn't too bad. About 16p/kWh at my local Tesco.

Did you get it signed off by a structural engineer, assuming it is roof mounted. That is the only thing, apart from all the kit being approved (manufacturers datasheet should cover that) that you may need.

Citation required Bollocks to citations at that cost, I would be burning coal in the back yard. Maybe drip some water on it to make H and CO. The H as fuel, the CO to speed up the end.

Yes, but it was more from a practical viewpoint. What is the fundamental differences in circuit design. Though these days it seems you buy a complete chip that can do the lot. My gut feeling is, if you run things at a higher voltage, you can get away with 'lighter' cabling and controls.

Our old mate, @Ed Davies has been looking into this. https://edavies.me.uk/blog/ as did I a while back. As usual, no real conclusion.

I asked a question, a year or so ago, about the best way to control the power of a resistance heater. Control the current or the voltage delivered? Not sure if it was a good question in reality, but no one answered it anyway. Really a matter of what is the best way to control power when there are several variables. (While I was the best in my class at university, better than the lecturer, my knowledge is very limited in reality)

Then in most cases it won't get done As they say, "Can't help stupid". It will highlight that bewildering mentality that when property prices rise significantly above inflation (as they have done in many places for 25 years), people think they are better off. Not as if you can pay the gas bill with a brick from your mansion wall.

Isn't part of the problem that PV cells are basically current source devices, and the current they produce is proportional to the light they receive.

That is easy, the property owner. I am a bit miffed that the daily rental on the electricity meter has gone up, in part to pay the debt on the failled suppliers. No one, who save on their bills through these bad businesses, offered to but me a coffee even, let one pay part of my bill.

Gives me something to work to tomorrow.

Chicken. Ultimately, I want to use the least amount of power for a reliable connection. It is a very good fix all the same.

I got half of that.

Not had a problem either (except that once, which was probably my fault). May have to play about and see if it is the CPU speed or the Core Voltage that is the true key to the problem.

It is 4 kW. kW is power, kWh is energy. kwh is nonsense.

4 years at Camborne School of Mines maybe.

We loose ~5% of the natural gas due to distribution. And then there is the processing losses, which are less for large users than domestic users. Electricity is also more useful than gas. If we still had gas lighting in our homes, airtightness would have to be above 10 ACH, not below it. I also doubt that many gas boiler actually get close to 90% efficiency in reality.

Solar slates are the expensive, low performance option. Much better off looking at traditional modules. There are a number of methods to have them fitted. As for trying to heat a house with them, that is going to be hard. Winter production is so much lower than than your space heating demand. Heat domestic hot water is your best option. A dime cylinder is all that is needed. Car charging may be useful, but there is generally a minimum load below which a BEV will not charge, so you may be importing electrical energy as well as using all the PV production. Depending of your electricity tariff, that could be expensive.

Rounding errors when converting from imperial to metric. A kWh is based on SI base units.

No login problems today at all. Fingers cross @Radianhas posted up the very best solution to this problem. I may have to go and post it up on the Raspberry Pi forums.
