UK solar doldrums
« on: January 11, 2018, 08:32:20 pm »
We seem to be surrounded in clag, the utilities must be rubbing there hands with glee!!

My daily output here in Norfolk has been zero for several days and down to 0.2Kw/h average per Kw installed this week, anybody doing any better ?

According to http://www.gridwatch.templar.co.uk/ UK solar output peaked at ~2GW today. vs 4GW last Sunday.
There are lies, damned lies, statistics - and ADC/DAC specs.

i dont think the suppliers are too happy actually.
there is a gas shortage right now because a transfer center in Europe went up in flames over the new year.
the u.k. is now breaking it's own sanctions buying emergency gas shipments from Russia - and i bet they are not selling it cheap!!

why not? supply is tight so double the margins. end consumers will pay for it...

Many individuals are on fixed price contracts, and they change supplier regularly.

I would expect that businesses have similar arrangements.

blame the government.
they are to blame for alienating the region's biggest fuel suppliers.

we could have cheap russian gas and cheap iranian oil,
but oh-no - that would upset the stateless shadow-scumbags  working with government to carry out petty revenge against country's that are still independent from central banking!

It's a long time since I looked there and I don't think they used to have solar seperated out, anyway I note with interest whilst solar has dipped badly in the winter Bio is takeing off and I spent a few days this week making compost from all the annual hedge cuttings etc, now theres an idea  :-+ principle must be similar to brewing beer/wine right ?

I didnt think we had a gas pipeline connection to europe BUT we have shutdown one of the feeds from the north sea due to a fracture that will take a good while to repair. Interesting that story about the russian LPG ship unloading at the thames estury, it was claimed to be a transfer shipment only and anyway I thought our bulk LPG import was tother side of country (all locations left vague deliberatly).

I'm not familiar with those kinds of contracts.

in the UK you sign up for an energy supply contract that lasts for a certain time. The price is fixed for the durationso if there is a massive hike in price you don't pay it until you need to renew. On the one hand you get a better deal, on the other you are locked to a supplier for at least 1 year. suppliers often offer a discount on your first year to get you hooked and hope you don't move on after the first contract is up.

I am suprised that nobody so far has added there own figures so I added a survey (wow that was easy) as a teaser, maybe I am verging on being an ECO nut hahaha please join in the fun :)

I'm kicking out about 200W each day but my panels are a bit shaded at the moment being in the garden and with part of a tree in front of them on the ground. The panels are 1.5KW maximum output is usually 1.1KW in the height of summer.

You must be somewhere sunny like Bristol :) I am getting only 30W peak and like 9W average atm from a 1.1Kw array but hey it's really awfull weather here atm. BTW my energy logger is a bit primative (as it was written by me) and has a threshold of 100W/h before it logs anything, hence reporting zero the last few days!
Is that 200W instantanios or watt/hours or watt (pun) ?

that's 200 watts for the day I think I have seen it peak at 150W instant. Oh you have a threshold of 100W? you didn't design the powervault did you ? ;)

What do you mean "200W for the day"? If it is for a day then the units should be kWh or Joules (i.e. energy not power).

What do you think ? what would my inverter say? how would I value it and how do the rest of us value it? we are talking standard energy delivery not physics, what unit does the world use to measure generation and consumption of power????

This is O-level physics; look at any electricity meter: kWh.

Watts are by definition Joules per second, i.e. energy/time. Hence kWh is energy/time*time => energy.

In the context of power systems, energy/kWh indicates how much useful work you can do whereas power/kW indicates how fast you can do it.

If you like analogies, in the context of cars kW indicates how fast you can go, kWh indicates how far you can go.

Of course it is KWh, in this context it should be unmistakably KWh!

Greenwashers and publicity machines frequently get this wrong through ignorance and/or deceit. It becomes impossible to determine what their statements mean.

Yes I'm sure they do but we are talking about a standardised thing using standard off the shelf kit, I'd be very surprised if anyone inverter stated anything different for "KW" than KWh, most people don't even understand the concept of instantaneous energy at which point you end up talking joules and coulombs just for it to make sense in your head.

So, you meant 200 kWh / day from your 1.5 kW panel array?  :-//

I got 70Wh out of my 100W panel yesterday, but there is no load other than an old FLA...

I don't understand your statement?
Power=watts or kW
Energy=joules or kW*hr or MW*hr ....
