With the original FiTs, all income was tax free. That may not be the case if you sell to Octopus. I would wait to see if Octopus buys Bulb. Lots of debt to recover.

Probably how I got away with using only 1 kWh yesterday. Think last week was about 18 for the week, but may have been 28. Looked at my bill and noticed that my standing charge is 57p a day. That would buy 3 kWh of gasoline. Could probably get 2 kWh of electricity and thermal out of that (seen a small honda bike with a water cooled 125 cc engine). Seems off grid at 40p/kWh would be viable.

I got some plywood shelves the other day, going to make them into plywood shelves.

Much of it depends on how much DHW is used. I use about 30 lt a day, other may use 200 lt.

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.
