After a pretty awful long time with hardly any sun here on the south coast, next week looks like a peach.

Cool, breezy and wall to wall sunshine for at least the next 5 days. extrahappy





I am going to let my battery bank discharge to within an inch of its life today in order to hoover up all those photons.

I expect 60+ kWh's every day. fingers crossed!

Hopefully it might take my mind off my Coronavirus anxiety.  Shocked

Due to some thin high cloud from time to time I did not manage my forecasted 60+ kWh's yesterday. facepalm

But I still achieved my highest daily yield this year so far, of over 54 kWh's. extrahappy

Outstanding result. Do you thermal store or more traditional storage heaters or similar?

Best day this year, 3.17 kWh. That's 75% of my daily use Smiley
I just wish I had a better battery.

I can thermally store a 300 litre tank for my hot water using either my heatpump or dual immersion heaters running via an Immersun. I can heat my house with oversized radiators using the heatpump or a gas boiler as a backup. I also have two storage heaters which can run via an Immersun.

Nice one, a good multistring approach. I am trialing a storage heater this morning. Must be corona boredom kicking in.

Its a phone / ipad app, "Weather Pro", it uses a composite of several weather models and I find it pretty accurate, at least for a day or two ahead.

Its free app, but I pay a small extra (about 5 a year) to get slightly higher resolution data.

Another good day, 4.37kWh, a new record for me. With the battery at float, I used most of the surplus in my oil-filled rad, on nearly all day. Boiler only fired-up twice all day. If my battery was any good, that is 100% of my metered use. Instead, it saved on gas.

Do you think its a coincidence or is there something factually based in so far as every time something causes the aviation industry to be grounded en-mass the skies suddenly appear to become a lot clearer and brighter with less cloud ? The Icelandic volcano, 9/11 aftermath and the current CV outbreak to name but three instances.

It was noticed after 9/11 and the term "global dimming" was coined - basically aeroplane contrails cause a sort of high altitude cloud, get rid of that and you have a more transparent atmosphere hence brighter sunshine and colder nights.

Hi Stig,

Thank you for confirming that, I hadn't been aware of the term global dimming before, I suppose its a bit like seeding as the contrails and the particulate from engines must act as seeding nuclei for ice crystals.

I have to say I don't mind the reduction in aircraft and the clearer skies but I wish we could do it as a societal decision rather than the usual disaster response.

Generation on the west coast with a westerly facing array has increased significantly over the past week and we are consistently in to double figures each day

Another record for me, 4400 Wh. GCH staying off longer.  Smiley
More power than I can use or store unfortunately.
