Solar panel production figures

You are your own worst enemy…

perhaps I should add another floor. That would solve the problem!

Ultimately I just need to find half a million down a sofa somewhere to upgrade to a nice big house without any neighbours lol.

I'm lucky that I'm detached and south facing so the house opposite is over 30m away so it's never going to be an issue. From about 230pm onwards in the winter I go from a 6.4 system to a 4.8 system, obviously as we move away from winter the time becomes later and later.

But not me, currently at 27kWh and still generating 1.8kW :D

Yeah but you are a mad lad…

My goose is well and truly cooked now, fallen off the optimiser failing cliff. Down to a mere 740w output despite having half the array in sunshine.

Still, should comfortably crack 25kWh for today which is pretty cool to see - on an absolutely perfect day in early feb it got about 18-19kWh. Today wasn’t quite perfect and it’s already smashing another 6-7kwh just a few weeks later.

EV arrives this time next week, can’t wait!
 
Don’t know, would make sense!

I believe the optimisers are doing more than just bypassing, they do some jiggery pokery to optimise partially shaded panels more than would be possible with bypass diodes

“Although bypass diodes somewhat lessen the effects of shading, the Tigo optimizer recovers more lost energy, thereby increasing energy production. The optimizer calculates the maximum power point of its connected module by using patented software algorithms. The optimizer "senses" a reduction in current caused by some shading. It adjusts this module's current to reflect the correct “virtual” resistance for each module, thus preventing the lower producing module from dragging down the production of the higher producing modules in the string.”

What is clear though is that they have their limits… I would certainly have had more output during such times with micro inverters treating each panel as an individual power station unrelated to the others, although somewhat moderated by the reduction in round trip efficiency to the batteries due to DC-AC-DC-AC.

Slightly academic I suppose - the system is still clearly capable of making a lot of power even at this time of year.
 
Problem with microinverters is that it's a bigger faff to upgrade and or maintain if they go wrong. And adds more expense. Though that said for someone with shading it might be more of an advantage?

Anyway it's not as if you're in a bad situation with your set up.

I don't know if I'll get to 25kWh today no idea what the sun is looking like at home, from the CCTV it looks bright and sunny but can't tell what it looks like on the roof!
 
Slowly ticking down, shading looks to have stopped at 15:20, but obviously the lower sun meant less generation, but looks like i'll be cracking 20kwh for the first time since October! Batteries fully charged and had the AC on heat to minimise export.

I think that’s generally a problem most people have with solar, ultimately anything going wrong = expensive scaffold for the majority of houses. All very well having a 25yr warranty but the warranty won’t pay for the scaffold to replace your single failed component!

25.3kWh today and it’s trickling in so probably more or less done. 9kwh exported which would have given me about 9-10 miles of range in the EV if it wasn’t somewhere on a boat from China lol

An appalling day today, completely overcast all day. Managed a whopping 2.8kW and managed to get the batteries to 18%. :rolleyes:

We haven't beaten the 14.4kW we got on 6th February yet, such is the lack of completely sunny days in the last few weeks.
 
14.3kwhs today, which is a record, but not quite the 15kwhs i was predicting……i lost about an hours worth of evening sun….

but after the real bad start to the day and lots of cloudy spells, breaking my current record is all good
