Solar panels and battery - any real world reccomendations?

proper gloomy morning but ticking over at 2kwh.
 
Yeah, charge completed on the batteries at 1am and not used a drop from the grid since then and had AC running non stop now it's free :D Will need to adjust how I cook stuff at times as my hob can consume big power when on full power (induction) but if its a few pence per day its nothing. Need to get my SEG sorted, now the suns out it's kicking out 6kw with no troubles.
 
Would that small shadow really make a noticeable difference?
I think its because it would affect the whole strings efficiency and this would be most during the shorter days when the shadow is longest.
Good - even better the scaffold was still there to make it a far simpler task!! :D
Yep, got up and took down the TV aerial and cleared the gutters when they left yesterday, so thats something I won't need to do up a ladder!

@HungryHippos guys were really good, just keep them topped up with Tea and Coffee!

Awesome work looks great!

Definitely looking forward to mine getting added, cut down those bills a bit, my last utility bill for a month was £200 actual usage so £6.66 per day (evil number!).

How soon after DNO were they out? I have 28/07 for my "no later than" date for approval, so hoping to get it all in ASAP to stop paying the grid people so much :)

Bonus of also being able to use my AC more often without the grid, which makes it far more useful than it is now when I only use it really warm days when I need it due to cost.

With micro inverters, or optimizers - no. However if the panels are wired in series then the section of the panel in shade acts against the whole set of panels it's wired in with.

With 6kw at hand, you could argue it makes very little difference. However seeing how easy the fix is, you may as well do it now.

Just left mine on all day now at 20c ticking over and meant I've had a nice comfy day. DNO came back on the 20th as predicted and they had it booked in the day after, so a week?

I've generated 25kwh since 05:15 this morning (20 minutes after sunrise) with enough generated from 06:15 to cover my base load.

25kwh so far.. that really is quite something. Do you finish on around 32-34kwh at this time of year as a result then? Have you worked out what the winter should yield from this 17? Panel configuration yet based on other user data for this sort of set up or are you in the dark with it?

Find out at the end of the day, still getting 4kwh atm, and should be generating for another 3ish hours yet, so will probably be about that. First day with it, I did have it somewhere but can't find it, but somewhere around 5-8 kwh on average per day in the deepest, darkest months of the year.

I’ll keep an eye on this then as real world use be the nonsense most quote when selling differs significantly.

My dad has a system in place consisting of 26 panels and has space for another 26 should he wish (bungalow faces east west so makes no odds where they are placed).

Due to his super efficient home, retired status, completely different usage pattens and lack of battery storage (he’s had it a while so gets a nice chunk paid back) it’s difficult to really gauge what is going on with it all but all I know is he just about breaks even over the year suggesting his older tech panels are significantly less efficient than what you get today rendering what he tells me somewhat moot..

Looks like a good clean install too your side! :)

Watch some of the Ozzy installer guys busting this myth exaggeration. Well I watched a few and came to the conclusion it was not as bad as the guys selling the optimisers are making out. You also have optimisers to maintain once installed. Installer folk may be elsewhere globally like U.S but the two I recall being Australian made me rethink the advertising/marketing angle.

ed- think this was one of the Oz dudes.

Started dropping off about 16:30 as the sun moved round to the west and is now at about 1.5kwh even though there appears to be no direct line of sight and 36kwh produced overall, so seems like a good day will be 40+ and even a cloudy day 1.5kwh was the minimum load from 08:00 to 11:00 before the sun came out proper.

It makes a difference even with optimisers, but its really quite small, but adds up over time. Without optimisers the effect would be higher due to being spread across the entire string.

The below shows totals per panel of our Solaredge system installed in December 2015, the two panels at the top on the right have our boiler flue cast a shadow over them during the day, hence why they are the lowest pair on that roof.
