    That's a good idea Murdoch.....I'll look into that! Noticed someone down the road had it fitted last year and For the life of me I couldn't think why.....until now!

    If you don't have mesh installed around the perimeter of you panels I would say NOW is the time to add them when the scaffolding is up We have mesh around ours but I left a slightly larger gaps between the top and bottom rows and the ruddy pigeons can drop in between them ........ and like doing that. So I am in the the process of trying things to get the gap filled up! Fingers crossed it won't mean scaffolding.

    LOL.....the pigeons sit on her roof as well, but apparently only poo from mine

    That must be quite difficult to do. Perhaps she's done something to upset them.

    Glad you mentioned that. My installation is on a bungalow roof in a relatively rural place and I've often thought the space behind looked ideal bird nesting territory. It hasn't happened yet, over seven years, but I will continue to keep an eye out each spring. Any visitors will be quickly given their marching orders before they can get established..

    Very interesting!.......there's so much more to it than you think! We do have a lot of pigeons in this area and my neighbour was only saying the other day that they sit on the edge of my roof and do their business on her pathway! I'll highlight the fact to the contractor....

    It's only an issue if something goes wrong, or someone put panels on a knackered roof. Other thatn that they should be fine for 30 years or so. I've only come across 3 fialed panels, 1 was directly under an aerial and the birds shat all over that panel eventually cuasing a hot spot and burn out, the other 2 were donw to a prat with a pressure washer cleaning the roof and damaging the anels in the process. The most failure is water ingress into a connector, cable tying the connecotrs to the rails stops that, along with actually doing the connectors up properly in the first place with MC$ spanner which costs a couple of quid. Pidgeons can be an issue nesting under the panels, the build up of debris can cause earth leakage via the backsheets of the panels. The backsheets are slightly permeable soft plastic sheet, bits of stick sticking in it doesn't do it a lot of good.

    This highlights a problem with solar PV on a roof. To do anything with them needs scaffold which is not cheap and is probably a large part of the cost. My own are ground mounted at this house (shading from tress was the reason for that) and at the previous house they were on the garage roof which at a push you can access just with a pair of ladders or a small scaffold tower which you could DIY erect for a lot less than full on scaffold.

    Thank you for your replies and the ideas. Good to know that my moving the panels probably and hopefully hasn't completely ruined them over the 3 year period. So by moving a couple of them, I'm assuming I have unbalanced the strings and made them less efficient. Looks like I'm best off getting them sorted properly. Thanks again.

    Football is a huge profitable business and top flight players are in demand to maintain a teams popularity, success draws in the Shekels so you have supply and demand. The percentage of players earning top Dollar is quite small and I don't blame an individual for going for the big pay packet, why not if someone if offering it.

    Or let a cheetah loose at random intervals ? take a 25l gorilla tub fill,it to within 1" of the top with water at body temp insert elbow for 7 seconds remove elbow the size of the hole left in the water is how interested I am in football and is also a direct measurement of how important football is just saying

    Ah! Someone who shares my views of football.

    why do people want to watch a group of overpaid people run around a field for a few hours kicking a bag of air? make it more of a challenge and i might be interested. maybe have a few balls. some filled with lead. maybe a few small swimming pools with some sharks or crocs in it etc that they need to cross

    well i could have continued with 'but knows nothing about anything else electrical'

    I can never quite work out if its the players or lettuced British Mangement that's the issue?

    all cabling is designed with a cpc sized to suite its current rating. I would be more concerned about exporting earth outside the equipotential zone of the house on a TN-C-S system - that's why you need a rod.

    Problem with New Solar Installation

    sounds like they initially had the 'amp clamp' on backwards, hence the battery wasn't charging when it should be. Not discharging from the battery overnight sounds like they havn't set the battery 'mode' to self consumption. There's usually several different modes you can set the battery to work to, one mode is self consumption, ie use as much leccy yourself as possible. Another common mode maintains a level of battery charge to allow the battery to be used in the event of a grid failure to power key items, like your fridge or freezer, sonds like they have set it to this mode, hence the battery not discharging overnight despite having some charge in it. Most batteries have a wifi link and a battery 'portal' or phone app that should show exactly what mode you are in, and energy distribution ie energy from panels, current useage, energy being fed to battery / battery supplying energy to your house etc etc. Hopefully your installer has left you with this app to study?

    I think that's the nicest thing you've ever said to me
  24. Not keen on the immersions (pessumably with a 2.5mm/1.5 Heat resistant flex tail) on a 32A cirucit without overcurrent protection, although some will argue that the element isn't capable of overload, so not ideal to start. If you are putting contactors in, I'd just put a couple of B16 MCBs in the same enclosure to fuse down for each immersion

    It is not required to support main protective bonding so what makes you think it is undersized.

    of course, you know much more about solar than many of us

    Looking for some advice of powering a garden office. 6.0swa taken from the house already put in by Customer. Its a tncs system. There's no extraneous parts. Am I right in thinking that it will need a earth rod because of an undersized earth ?

    Seems I have a fan club OK, imbalancing strings does affect peformance, your inverter will be trying to find the maximum power point from a predesignated input curve, but effectively it has 2 curves to try and track. It will work like this but you lose some performance. Prices quotes for the works seems quite reasonable, but I suspect your inverter has just died due to old age. The old SB HF series hasn't proved to be especially reliable - check it hasn't got an extended warranty on it. I've always been suspicious of T jointing DC strings - it's a practice I've always avoided. If you are going to the trouble of lifting panels, I would ask your contractor to consider re-arranging the panels into 2 strings. Your new inverter will almost certainly have 2 MPPT trackers, put half the array on each input. It might not be possible with the thin film panels to arrange the strings like that, I really can't remember the electrical characteristics of those panels as they dies out a long time ago, but I would be surprised if what I'm saying can't be done. Depending on where the T joint is, it maybe possible just to rearrange the cabling at that point and not lift the panels. I wouldn't be looking to lift panels unless testing showed a break in DC cable runs.
