Solar panels and battery - any real world reccomendations?

A whopping 25quid saved this month from Solar

based upon my current 19.5p/kwh tarriff. Good data and confirmation I will be able to use off peak charging to supply pretty much all of my demand!

Edit - sorry 27quid, forgot VAT

Feel my pain of the inverter dying and not replaced for three months in the Summer, lost must be 1000 units @0.23p a unit
Still have sleepless nights over it lol :cry:

It all adds up. Accrue that over a year and you end up with a decent figure. That's an extra takeaway or 1/4 tank of fuel that you won't have to worry about!

Good idea. I've added mine and roof pitch.

Where have you added? Is this a shared file or something? Mine's south facing and 30 degrees!

Ah gotcha! Was wondering if Ronski had set up a shared google sheets doc or something for his table and I'd missed it!

Ron-ski · 1 Dec 2022 at 10:00

I've added columns for pitch and orientation.

Just done on a local copy of Excel.

Mercenary Keyboard Warrior · 1 Dec 2022 at 10:11

Seems to be loading ronskis workload up nicely

You need age of install in there as well, got to take that panel degradation into account

Freefaller · 1 Dec 2022 at 10:12

I also think we need to add dimensions. Number of strings. Number of inverters.

Oh and number of electrons moving in the wire.

And and and and....

Ron-ski · 1 Dec 2022 at 10:14

Sorry I can't hear you...............or see those suggestions :rolleyes:

john_smith · 1 Dec 2022 at 10:15

Agree on roof pitch and system age.

I think I must have a very good angle as it does produce very good numbers. It's a 4k array but only a 3k inverter, installed in 2012.

Ron-ski · 1 Dec 2022 at 10:18

@john_smith You must be earning some nice FITS payment with a system of that age, what did it cost back then?

Mine was roughly £6k in 2015, and finally paid for itself this year due to the increase in electricity costs, otherwise it would have taken a bit longer.

I'm figuring if we can keep throwing spreadsheet updates at him, he'll have no time to finish his new solar install and avoid creeping up the table....

Welshman · 1 Dec 2022 at 10:31

Just hit 2.5kwh's for the day already and not a cloud in the sky.....

HungryHippos · 1 Dec 2022 at 10:34

Need sum of panel kwh and average kwh per kw of panels added

Specific location I agree we could skip, but solar region may be a thing? like down to county level maybe?

Thats not going to work, but the weather might just hold things up, but there's still stuff I can do inside the garage come the weekend.

I'm currently working from home - brought Covid back from my holiday :mad:

Happy to add a county location if people want it added - just post a message, please add my location as ________ to the chart.
