If the ground mounted array is over 9 m2 you need planning permision.

Think that is dry mass. And i is kWh

When I was doing my post grad, I got accused of scaremongering about blackout.

If plants convert 0.5% of the suns power into useful fuel, and I doubt in the UK they are that good. A square meter will give you about 50 kWh.m-2.y-1. Probably only get half of that with timber combustion technology. So 25 kWh. So maybe a days worth of thermal energy. A 200 W (about 1m2) module at 15° will knock out 5 kWh for the whole of December.

Usually hidden behind pampas grass.

So will small time landlords. When the electricity bill is the same as the rent, don't thinkk the rent will be paid.

Does your system 'island', or are you still reliant on the 50p a day grid connection?

Makes me want to use even less. And buy a thicker jacket.

It is from a report by Cornwall Insight. They do seem to be being qute extreme with this one. https://www.cornwall-insight.com/price-cap-to-remain-significantly-above-3000-a-year-until-at-least-2024/

The usual way to measure a PV installation is to divide the output over a time period by the installed capacity i.e. 950 kWh/kWp. Suppose you could do something similar with the nominal inverter capacity.

We will once fitted 3.5 Wp of modules to a 3 kW SMA inverter. The instantaneous display showed over 3 kW every now and again. The cooling fan was at full chat. If under sizing the inverter, fit it where it can draw in lots of air, so not a loft or cupboard.

Can I call you 273.15? Or do you prefer 283.15

Just the name would put me off.

Probably fridges.

For similar reasons that higher education sells degrees that do not improve employment prospects or earnings. The market demands them, so they are sold.

Really should be called parasitic load. Base load makes it sound acceptable. 80 W us almost 2 kWh a day.

Called a new unit.

Call it the Westinghouse.

Not just the cold that is the problem. Rain can ruin an evening under the stars. So you need a roof. And no one likes a chilly wind, so walls (and ventilation if the wind is con carne). So going to be similar to a house. All it really needs is some sturdy glazing in the roof to look though. If only there was some walk on glazing available. Or just get a NASA feed:

Yes, there is only so much effficiency that can be got from electro-mechanical equipement. My two biggest savings have been from reducing heated water temperature and getting rid of parasitic loads, I still get miffed if I leave a 3W light on. I have never done the sums, but DHW energy usage, in winter, could be improved, I think, by pre-heating, even by just a few degrees, the incoming water. Then boost via an instantanious heater, powered from a PV supplied battery bank. Really down to where the largest standing losses are, thermal storage or battery efficiency. The easy way to to use a lot less, easy for me as I live alone and take an interest, harder for a family. Who can put a price on an arguement over the length of a shower. Well we all can, about 5p/minute for a 10 kW shower.

Was in short trousers then. I still am.

The main thnking is that water vapour can travel from the inside of the building to the outside, and weather, i.e. wind and rain, cannot travel from the outside to the inside. That limits your choice of materials and any ventillation between screen and the real wall. Ah, is this place in Italy. It may be the other way around, it depends on the local climate.

If anyone is doing a roof integrated system in Cornwall, I am interested in look how it is done. Tempted to copy the design in GRP.

I think I read somethign about this. Seemt o remember that it was 20W, then a bit more when tracking. Is the service good though?
