Solar pv is this right?

I think the reason may be that your east facing panels face slightly to the south and in the winter that makes a bigger difference. As the days get longer, I think you will start to see the larger array produce more. 

If not, it might be worth investing in optimisers, as suggested by @gefnew as your west panels do appear to be effected by shading more than your east array.

are tigo optimisers available in uk and if so what is the cost

Not exact science but this is basically what I have, with a 20Degree turn. The  chimney does shade but I wasn't expecting that to make the mornings and afternoon similar 

Hiya, is that picture orientated with north to the top? If so, then it looks like your panels may match mine as ESE & WNW.

Just as a guide, I have roughly estimated my average daily gen, which will be lower at the start of Feb, and rise to the end. For today I have an estimate of 4kWh ESE and 1.5kWh WNW. Obviously these are just rough estimates, but that will give you a guid based on my array sizes, so:

ESE 4 / 3.58 = 1.12
WNW 1.5 / 2 = 0.75

Not going to even pretend that I've got this right, but it may be a rough ratio you can use of 1.12 : 0.75. [TBH, I feel a little embarrassed posting this, as it could be so, so stupid, but what the hell!]

BTW, I also have a central chimney stack and are the northern half of a semi-detached, so shading issues, but helped with a Solaredge system to minimise the impact.

Thanks, probably not worth retro fitting these now, but maybe in future if I have scaffolding up then maybe. gefnew said:

I have 6x 410w panel, going into a Solis 2.5kw inverter 
String 1 has 2 panels east facing 
String 2 has 4 panels west facing 

My question is why since the installation in October have I never seen the panels produce more in the afternoon when 4 planels get the sun light? 

It is possible that your panels may not be producing as much energy as you expect because they are not optimally positioned towards the sun. The direction that your panels face, as well as their angle, can greatly impact their energy production. West-facing panels will generally produce more energy in the late afternoon, while east-facing panels will produce more energy in the early morning. However, other factors such as shading or weather conditions can also play a role in reducing the overall energy production of your panels.

It may be worth consulting with a solar panel technician to assess your system and determine if there are any improvements that can be made to increase its energy production. Additionally, monitoring your panels' performance over time can give you a better understanding of their energy production patterns.

Looking at the past couple of days this is what I was expecting majority of the time. But still surprised 4 doesn't make double 2. But this could be due to being wired in series? I'm certainly happy saving over £100 during the winter period
