Are We on A National Data Base Open to All

I have been bombarded with cold call around servicing contracts and the like synchronizing with 5 years since the installation.

All these callers have our personal details to hand and all are aware that the installer warranty of 5 years will have expired. I presume this will have been a standard period for reputable installers who could issue the appropriate certificate.

I have done a bit o Googling but I cannot find what this open database is, but I can only presume it is to do with is called on my installation cert. the MCS Certificate Register.

I presume other are having this experience, but where are they getting the information .

Grateful for any thoughts

Yes, I have to say that I've been contacted by various companies lately and would dearly love to know how they got all these details. My installer has folded / disappeared so it wasn't them. My FITS payments are handled by EDF.
I would like my details removed from this database in any case!
edit : Apparently a Welsh outfit has bought all the data for every solar panel installation in the UK. their new business plan is to sell replacement Solar edge systems to everyone whose current inverter is likely to fall in the next few years. Expect a phone call soon!

Update : They got back to me and quoted around £4.4k for changing the installation (16 control units, a new inverter, with a 20 year extended guarantee, scaffolding and team to install) if I was prepared to let them use my system as a reference point and around £1K more if I didn't.
I have to say I found this very expensive, despite the 20 year (i.e. no more inverters required for the duration of my FITS agreement) guarantee.

Any comments welcome…

Hardly competitive pricing, unless localized shading is really destroying the yield.
A replacement inverter plus 10 years extended warranty would be £ 1.5k + £ 200 install costs in my case.

I agree. Ironically, he did say at the beginning of the conversion that to simply replace our Sunny Boy inverter would be £1.3K + £300 labour. But he pointed out statistically that we would have to do that twice before the end of our FITS agreement…

I think the big selling point for them is their quoted 19% improvement in production and the 20 year guarantee on the inverter and optimisers. That 19% extra production would approximate to £350 extra/year in our case for 20 years = £7K.

Comes down to - do you believe the 19% improvement is really possible in a marginally shaded set up?

Other people's experience retrofitting with solar edge would be appreciated.

Unless their 20 year guarantee is underwritten by a reputable insurance company then it's only valid as long as they are in business.
Enecsys (micro inverters) went bust after about 5 years & their 20 year guarantee went down the dumper with them!

Hi pr_giles,
I had a Solaredge system fitted December 2011. SE4000 inverter and optimisers on all 16 panels. My panels face South at about 30 degree angle giving me an average generation of 3,718kWh per year over the last five years.

Interestingly this generation seems normal when compared to other 4kW systems. In my case I lost 4 weeks of generation in May 2012 when two optimisers failed shutting the whole system down and then again for 6 weeks in June 2014 when another optimiser failed.

So I would go for a simple system or I would want a guaranteed 19% extra over your existing system generation history or compensation. I would also want compensation for loss of generation due to any system failure and compensation for having to buy generation instead of using your own. Ten weeks of lost generation and having to import during May and June has got to have lost at least £500.00.

What you need is 100% reliability and system availability or that extra 19% won't add up to anything.



SolarEdge SE4000 inverter, 16 x Romag powerglaz 235W panels. South facing at 30 degree angle in Surrey just East of Gatwick and under the flight path.

ESS AC coupled system using a Victron Multiplus 24V/1600VA Inverter/Charger - 8.16kW Trojan 875 battery bank.

Hi,

Like backyard I have a solaredge system. 4kw 16panel. Unlike backyard since they where installed in 2011
they have operated without fault and generate just of 4mw a year.
I think that it has a lot to do with whoever installs them.
If you have any partial shading at all at any time of the year ,this is the system to get.

regards,
Gauva.

thanks to both of you for your helpful comments. i'll stick to my sunny boy until it goes and reconsider at that point. our shading is minimal, so the 19% increase i'll take with a pinch of salt for now.

Just had an annoying call from someone claiming to call from the ‘Energy Assesment Centre - Green Levy’ offering the do a free check on our installation - they had an appointment available at 11:00 (Call at 10:15!) - and check the system performance. Mentioned Sheffield Uni and that stopped him dead before he came up with a slightly different approach - what make is your inverter? I then asked how he had our number as we are in the TPS Scheme - phone went dead. Enough said
