    Optimisers 19th May 17 at 6:54 PM
    Hi All
    I have a small shading problem on three panels on one string due to a chimney.A search of the internet to see if there was a system that would cater for just the three panels in question resulted in the find of the tigo energy optimiser ts4r, which can be fitted to induvidual panels that are affected by shading and seem to work a bit like enphase kit.
    Just wondered if you chaps on here have any experience of the optimiser.
    Any info would be helpfull.
    regards

    Hi Chris type R
    Yes and it was quite easy, but have easy access to my panels two flat rooves to work off.
    here is a link to a video from sma.

    This is interesting. I have 7 panels in my small array with their own SMA inverter. Not sure I would need to optimise all panels (unless that has to be the case) and was wondering what ball park costs might be for, let's say all 7?

    I think the Optimsers are 50 a piece?

    Is anything else needed? Don't know?

    Suppose the other thing depends if your Inverter is up to the job of taking 'optimised feed'...... if that makes sense? (i'm pretending I think I know what i'm talking about).

    I see but think these are a bit different to the ts4r SMA solution gefnew was mentioning - my inverter is SMA SunnyBoy, so probably more luck in using their product without loads of additional expense but all a bit like searching for a black cat in a coalmine...

    Hi all
    yes about that but if you know anybody in trade cheaper.
    got mine from a company called ccl components.

    Thanks - I have issues with shade on mine, so have been investigating solutions.

    Do you have an idea of what sort of improvement you've seen ?

    Thanks all. I too would be interested in improvements. This is a document I penned a while back when I was last wondering about retrofitting something https://www.dropbox.com/s/2k06xp8bjehyx32/More%20on%20the%20impact%20of%20shading.pdf?dl=0

    I think I was thinking SE at that time but guestimated about 1000 to retrofit 7 panels including scaffold and labour. Looks like that might be the same for TiGo unless the installer would be prepared to use a scaffold tower at 1/4 the price of actual scaffolding (hired one for a week a couple of years ago from Jxxsxns for 75).

    Could probably do it yourself with good instructions or does it need building regs sign-off/sparks certification?

    HI
    I have shading early morning due to a chimney breast which covers thee panels. have two strings running sma 4000tl inverter mppt controlled,
    we lose a lot on the smaller string early morning but this has improved by cutting out the effected panels seems to work ok.
    but my monitoring is only by sunny explorer so early days yet but seem to work ok
    regards

    My Solaredge system on the ESE roof (light shading) is now about 1yr old and the total gen (per panel) varies quite a bit.

    The top roof has 13 185Wp panels.
    The top row of 3 panels (Velux separates 2&3 from 1) have generated 158.57kWh (next to chimney) 181.4 & 180.54

    The second row of 5 panels varies from 184.11 to 186.41

    The bottom row of 5 panels varies from 188.90 to 190.01

    The lower roof with 5 panels of 235Wp panels, gets shade from the upper roof that spreads downwards.
    The top row of 3 panels portrait varies from 211.2 to 216.67

    The lower roof (actually a canopy over the back door) of 2 panels is 221.92 & 224.58


    My WNW system is about 6yrs old with 8 panels (250Wp) the panels vary from 0.762MWh (next to chimney) with the rest varying from 1.11MWh to 1.23MWh.
