Make sure this is set right.

Then it is not vital, though it is useful as an accumulative total. Or to stick a CurrentCost onto.

FiTs or equivalent for your exports.

Is it just showing the last hour? Then a daily total, and a weekly total.

This is a bit more concerning as if you are claiming from your energy company, this is the numbers then need.

This could be the instantaneous power, 186W, which if it was a little higher for an hour, would be 0.3kWh.

Snow on the panels?

Interesting. I wonder what happens if you use a local network, with the settings on the phone, then the power goes when you are out. Not sure if that would be an unusual scenario or not.

Yes you can, my mobile phone quite often connects to the St. Marys' transmitter as well. And I was at Land's End yesterday evening.

If you have programmed the Shelly to come on at a set time, and then you have a power failure, does it keep the same state i.e. on, or does if fail safe i.e off. And can it repickup any times that are set? Or are they done on your phone/cloud?

No, I live in the poverty stricken, overpriced, far SW. Yesterday I was looking at the Isles of Scilly.

How do I get on this scheme?

It is because it is not turned on for long.

No. The 445W is the peak power the module will make under standard test conditions. Very rare day you actually get that from the module.

So might be time to decalcify.

@Spoogster Do you live in s hard water area and not use any water softening. An extra person in a house will deliver about 200W, or around 5 kWh/day (ish).

Or A watt is a joule per second. J.s-¹. 3,600,000 J is 1 kWh. Joule is the SI unit of energy, not the kWh. I think we should ditch the kills wot our and go for mega joule.

You do, you keep me sane. In years to come, historians will rewrite this, remember the victors rewrite history.

If you use 100 kWh in 15 hours, that is about 7 kW power delivery. Now some of that will be for DHW. Do you may want to go to the next size up to be on the safe side and benefit from a better CoP.

So should polyethylene. Except the whole process. I have never seen steel being mined. Though I have seen iron ore and oil being pulled from the earth.

Yes it will, there is no reason to assume that steel, which is a mixture of more than just iron, will not leach. Most 'tin' cans have a plastic coating these days. Modern landfill sites have to have an impermeable layer to stop leachates anyway. That is before calculating the different embodied energy and carbon, the opportunities to recycle efficiently and effectively, and the overall 'messiness' of the production methods. As always, these things are not clear cut, so research must be done before making a sweeping statement.

Why? I am sure with a bit of research it can be shown that neither a good to put into landfill, but an plastic pot can go in an incinerator and generate some electrical power.

Where are you getting this 2000 to 2200W figure from. The solar constant for Earth is ~1.36 kW.m-2 Module, that use the standard test condition are tested at 1000W.m-2, at 25°C and an air mass of 1.5 kg.m-3 For annual yield in the UK, work on 1 MWh/kWp installed (assuming you don't have a system has shading, and is less than optimal azimuth i.e. North facing.

Well the Brexiteers tell me it is because the majority voted for it.

No, just something I heard from some electricians a decade ago. It would be in the latest electrical regs, whatever edition we are in now.
