    help with solar pv - south west london 5th Sep 16 at 9:45 PM
    Hi Everyone,

    I’ve been thinking about getting solar panels installed at my place and stumbled on this forum – what an amazing find! I’ve learnt so much from reading all the posts. I have got two quotes so far and the prices I have received are (1) £9700 for a 3kw system (2) 7300 for a 4kw system. Both solutions were string inverter based solutions (growatt). This seems a bit pricey to me. I am based in South West London. I’ve been through the solar PV FAQ. Appreciate any advice on this.

    because you simply can't admit that you called it wrong on PV, 6 years ago.

    Someone called George Monbiot wrote a superb article on the folly of FIT, which is as true today as it was then; despite your pathetic attempts to discredit him by clutching at straws. Your obsession with solar is worrying.

    Talking about getting it wrong, would you like me to cut and paste the page after page of your posts(in your inimitable style) of detailed explanations why solar farms are not the way forward?

    Now you spend your time praising solar farms searching the internet and compulsively cutting and pasting from every Solar industry publication.

    And you are back to that joke Monbiot article again. You never learn. You are the gift that keeps on giving.

    So I guess you're still not ready to admit that PV has been successful. Perhaps when all your single pensioners, in electric flats, have to start paying for Hinkley, when the subsidies for PV have reduced to zero, you'll change your tune.

    Then again ..... probably not, you're in too deep, and you just can't stop digging!

    You didn't answer me last time, so I'll ask again - Did PV run over your dog?

    Cardew, since you quoted me from a different context I feel entitled to express my opinions. I'm inclined to agree with Mart. Because:

    1. You claim that repairs are 'probable' with no evidence to back it up. Occasionally we hear of queries on here about faults developing but remarkably few given the number of people who visit here (and I would have thought it would be a first port-of-call for many). 'Probable' without justification is misleading. A reader would be forgiven for thinking you were suggesting probably faults with panels from the way your post read.

    2. Your original post didn't appear to be dealing with Inverters which are a different issue - it's acknowledged that potential replacement needs taking into account and no-one is shy from discussing this. However the situation with these is getting far better with lives becoming longer. There is every possibility that a new inverter will now outlast the payback period.

    With hindsight, it may not have been appropriate for me to use the word 'repairs' when referring to potential inverter replacement but obviously I didn't expect my post to be used in a different context. I can't even remember making the comment and am certainly not going to waste time looking into it.

    I would have far more respect for you if you came clean with enquirers on your position before offering seemingly unbiased advice.

    Of course we have our position too, but that comes from our experiences with PV, learning a lot of lessons and pitfalls and of course wanting to pass on any useful advice we may have.

    As Mart. says PV is a useful and now economic part of the generation mix. Investment in it has been justified and it's continued uptake is only to be encouraged - but with care. Which is why so many of us are concerned that we help people to make the right decision. I wait for the day when you do anything but try to put people off.

    Obviously the diagnosis of a faulty inverter and its replacement comes under the generic term 'Repairs' that being a term you - as you acknowledge - and others have used for inverter replacement.

    If you care to re-read my initial post it is advice on economics given the prices the OP quoted, which the OP thanked.

    You of all people are aware that Martyn's stupid response to me - and they are stupid - was antagonistic. Had anyone else posted exactly the same message as mine - especially a member of the MSE PV club - he would no doubt have bestowed his thanks.

    Do you really feel you need to take Martyn's side!

    Cardew, we can go on knocking heads, I can continue to laugh my socks off at your nonsense, but is it now worth it?

    Have you really not realised that you've been 'explaining' why PV doesn't work for so long now, that you completely missed the point when it did work.

    Once UK PV became cheaper than off-shore wind, it became a valid member of the UK RE mix.

    Once PV became cheaper than nuclear, it reinforced that position, and brought low carbon generation to the demand side.

    You spent a lot of time stating that hamsters on wheels were better than PV, yet domestic PV is now (today!) generating leccy at a lower cost than HPC will generate in 2028. So those 'ickle 4kWp systems on rooves' that you hold in contempt, are cheaper than a future 3,200,000kW nuclear plant - that's a lot of hamsters!

    The weakness of wind and hydro in the summer months, requires a summer specialist to prevent those who only focus on what something doesn't do (like PV at night) from criticising them.

    The moment you finally let slip that you were a nuclear supporter, your anti subsidy arguments collapsed, particularly given that PV FiT subsidies go back to the demand side, whilst nuclear subsidies go back to the supply side - and in the case of HPC will go to French and Chinese governments.

    If you want you can criticise all RE on the grounds of intermittency, but an appropriate mix of technologies and storage remove that argument. And nuclear is not immune to storage since it will also require storage to exceed ~16GW, since it will start to bump up against minimum night time demand. But nuclear can't demand follow*.

    I have no doubt that you will keep arguing, but at some point you need to realise that it's over, you are trying to wrongly predict the result of a race, when the race is already over.

    Mart.

    *HPC can be ramped down to 60%, but since almost all costs are CAPEX, not OPEX, there will be next to no cost savings, so ramping down, simply pushes the unit cost up. Also, under the 35yr CfD subsidy, ramping down would reduce guaranteed sales by 40% of 3,200MW, which would lose France and China approx £3m per day. M.

    Hello all, Apologies for the radio silence from my end. I decided to stay the course with PV, having given some weightage to the green aspects. I finally decided to go with 15 Solar world 285 panels and with SolarEdge inverter. (9 panels South and 6 panels East) £6800 for a installed capacity of 4.275kw. I know I am paying a premium of around £750 (or more), at these prices. None of the e*ay based suppliers were forthcoming with proposals. That made me think that after sales service could be an issue with these suppliers. I am not much of a risk taker and decided to go with a local supplier and pay the premium, after getting very good references from his customers. The spouse and and I also felt that the said person was honest when we spoke with him. Thanks a lot for the support and advice from the forum members. I will keep you posted..

    Finally, pulled the trigger on this project and placed the order. I was hoping for a vendor who will not ask me for my first born!! Turns out the wait was futile!!

    Although I (with lot of difficulty) got some attention from google earth jockeys - with some very aggressive pricing, I could only get the one quote from a guy who did the impressive bit of turning up onsite, climbing up the roof and measuring. Pricing £6700 for 15 X 285's (4275w) I think the exchange rates post Brexit have also played a role in keeping prices high. Thanks again to this group..

    Another question - my leccy supplier don't do FIT tariff. Can i apply to any of the other suppliers without changing my supply over to them? EDF seem to have a good reputation for paying out quick.

    Affirmative. Payment of FIT is not tied to the firm who supply your property.

    You can keep FIT payments with the firm you choose for the 20 years.

    Hiya. I'm with EDF and they are excellent. Also the Green Team is really helpful, which might help if you need to contact them about the FiT application.

    If your leccy provider doesn't 'do' FiTs, you should be fine. The only restriction is that the Big Six won't accept you for FiTs, if you have an account with one of the other Big Six (or their sub-companies), sort of forcing you to register with the company you are with - but that doesn't sound like it applies to you. So if you have any plans to change supplier now, you may want to register for FiTs first. Once the FiT is set up, you can switch your leccy account as and when you wish, your FiT account won't be affected.

    Thank you all for the advice and suggestions. We have finally installed the system yesterday evening. System installed is a 15 X LG 310's, 4.65KW, with SMA sunny boy 3.6 TL inverter.
    Paid £6100.

    Chose to go with LG since we had concerns whether solarworld would go the sun edision way. Figured LG might just be around for longer (time will tell!). Although I quite liked the solaredge solution, the fear of future scaffolding costs should optimisers fail, put paid to that! Therefore SMA inverter.

    Installation was completed in one day and installer generated the MCS certificate on the spot and helped me fill in the FIT application form. Very good experience throughout the install. We chose to go with EDF energy for the FIT payments.

    The system has generated 7611 WH so far today. It was weird watching the leccy meter run backwards. Have told the supplier extraenergy to do something about it. The SMA portal is good with reporting. I thought I will report here, before updating the generation thread.

    Thanks again all!!!

    Please could you advice me on what documentation I need from the solar PV installer for warranty and insurance claims etc...My installation has 5 year workmanship warranty.. What happens if (god forbid) my installer goes under?

    I have gone ahead with a string inverter (SMA) to avoid the potentially costly failures on the roof... I have found out that I need to inform my mortgage provider and home insurance provider. I will do these 2 things off within the week.

    The FIT application is now processed through EDF and they have sent me confirmation that all is well etc...

    Another minor issue is that I am finding PV monitoring very addictive

    Apologies for this unstructured preamble... but am i missing anything crucial ?

    Hiya, congrats.

    Is the guarantee 'insured', in which case you want a copy of that to prove you are covered if the installer goes through.

    Hopefully your mortgage company won't bat an eye at this, they just need to know if you make any significant changes to the property. If they are at all concerned, then they are probably misunderstanding the situation. Make sure they realise you own the system ..... perhaps mention that your income (ability to make mortgage payments) has now gone up for the next 20yrs.

    The same goes for the insurer. Check that the PV system is now simply covered as part of the building structure. It should have no effect on your premium at all (unless there's a small fee to make amendments). You probably have a silly rebuild cost that is many times greater than would be needed.

    Million to one, but read the EDF contract before you sign and return it, just in case they've made a mistake with the FiT and/or export rate (unlikely).

    Addictive, nonsense, I've had PV for over 5yrs, and any day now I'm going to stop recording daily generation. I can stop anytime I want ....... it's up to me .......... I want to keep doing it .......... look, just get off my back OK!!!!
