Renewables: "talking 'bout my generation"

I may well do that, thanks. I am already on PVOutput and I compare myself to two nearby systems.

Hawaii so far, how will the afternoon do...

That's quite neat!

I need to download some data myself from the inverter and start comparing. That site I posted looks really useful for getting a comparison with a bunch of PV systems though which is probably the best practical comparison one can achieve.

Just signed up to the Sheffield Uni Microgen DB... will add my outputs when I can.

I never got their confirmation email...

21.24 KWH's today!!

My first Hawaii!!

In extra energy saving news, after extensive negotiations, we are changing our boiler to a combi to ensure sufficient hot water.

Likely to be Ebaying a slightly used Iboost and an expensive digital pumped Mira shower system shortly....

11.97 kWh - tantalisingly close to a "6" - a bit surprising actually as there was the occasional cloud. That was the best day since August 1st!

Indeed, they are both arbitrary.

In what sense is PVGIS, which takes account of many variables, "arbitrary"?

I must get round to uploading my pvoutput stuff, I'm months out of date - either that or give up on it. It showed I was doing passably well compared with other local systems, but nothing spectacular.

Incoming picture taken at 15.45 this afternoon... not brilliant but hopefully clear enough:



The chart shows that nearly everything was generated before 15.00.
The blip just around 13.00 was when we had to power down the inverter to fire up the SolarImmersion, which is working a treat!



So, the shadow on the roof from the chimney - is that robbing me of afternoon generation and might be worth looking at optimisers, or is it nothing to worry about?

Oh, and what to do about the flying rats?! I don't want to kill them (ok, I do!), but would an airsoft gun (onbviously non-lethal) be an acceptable teaching tool to encourage them to poo elsewhere?!

Thanks again to all! And my first 5 O

In the sense that historic isolation levels cannot determine future levels.

To get a sensible comparison you really need to compare with other installations in your area.
