Total for day 11.8 Kwh.

Just checking my maths. A 2.5kWH system should work out to produce 62.5% of a 4KkWh system?

So, yesterday Eric's total was 11.8kWh, mine was 7.3kWh, 62.5% of 11.8kWh works out at 7.375kWh - bang on what I ended the day with. :T
Are the Maths correct?

Washing Machine is on; Dishwasher next, producing 2.175kWh between clouds, so far today--4.2 kWh:j

8.2 Kwh - 62.5% of which gives just over 5. One peak of 3.2Kw; several >2.5Kw. Alas, no peak has lasted long enough to get excited. Did manage to pump rainwater for WC flushing & have done a bit of cooking.

But the SSW orientation should explain all; If sun shines late evening you'll soon catch up.


If the met office seaweed is working right, tomorrow should have us all dancing in the streets. If not, not !

Well Eric, you must be up around the 13 kWh by now, I am hitting the 9.4 kWH at 15:00. Lets see if the calculation works!

13.04Kwh at 15:40

But it's really not that simple ! A belt of cloud over one of us but not the other might change things dramatically. As it happens, today is a day when multiple belts of cloud are moving past quite fast so although our peaks & troughs might be at different times they'll balance out.

There's also the different roof angles to consider. Ideal slope today would be around 40 deg - so mine is too shallow & yours too steep - but last month (or again in August) yours is ideal and in depths of winter when yours is too shallow, mine will be much too shallow

It's a bit early in the day to get the dancing shoes on, but we've notched 3.9kWh as of 0840 and currently generating 2.5kW. Looks like the first proper summers day out there in cider country, not a cloud in the sky. Bit too early to wake the neighbours with the lawnmower, but the washing machine is on.:cool:

Fingers crossed for a generation record, not had one since early April and the sun is up for 2hrs longer.

Hoping not only for a record, but our first 20. We were generating 2kW at 7am, now holding at 2.85kw, and 7kWh's at 10am.

Now, should I add a small west system, to compliment the east?

Too much excitement has jinks the weather, more cloud than blue sky here now. :mad:

She's getting there, 16kWh done, and running at 2.85kW (did sit at 3.1 from 11 till 12.30). ESE system probably good for another hour, then will drop off quick with this blue sky. What I really need is for the sky to go white, then we could get 800W+ till 6pm or later, otherwise, 200ish!

Edit: Just checked the weather forecast for Cardiff, solid suns each hour till 2pm then cloudy suns the rest of the day - perfect. Exactly the same tomorrow - double perfect. I'm hoping that piece of seaweed they got off Eric is still working! M.
