    SmartPV for Solar Panels

    SmartPV for Solar Panels 9th May 17 at 4:32 PM
    I have existing panels (since 2011) and had a knock on the door from someone saying I could generate an additional 25% by installing a SmartPV onto my inverter.

    Is this just another way for solar installers to make money from another source or is this legitimate. No idea of cost (they said it would repay in 6 months) and have a no obligation appointment on Friday.

    It just monitors what's available and let's you know when you have watts to spare.

    How can any device generate more electricity than the solar panels already do? Other than something that cuts shading or the like
    Remember the saying: if it looks too good to be true it almost certainly is.

    Sounds similar to something that I was offered over a year ago.

    Take a look at this thread.

    http://forums.moneysavingexpert.com/showthread.php?t=5453777

    I have spoken to my installer in the last 6 months on another matter and they again asked if I was interested in it.

    I said when they can show me 2 systems very close to one another. One with the PV+ system and one without and they could show me the improvement then I would happily buy it. Till then I feel its not worth squat!

    Had a visit from sales rep since original post.
    These were his stats
    Generation baseline is 2500kw/h per year which equates to an performance increase 625kw/h, which yields a return of £14478 for reminder of FIT or a 12.5% ROI and not to mention 338tonnes of CO2.

    The price? A small £3500! By the way, if I want to be part of their marketing they will offer me a £250 discount. Sounds a bit like double glazing tricks!

    Various guarantees were mentioned including the lifetime of the inverter and the panels. I did ask what if they went out of business (like my installer did) and he said of course they wouldn't and there would be indemnities (no further information was provided on this).

    Apparently they have a new product coming out later this year to save 50% of my energy bills.

    Safe to say I am not signing up.

    I had a call a couple of evenings back. Lovely woman who offered to sell me one of the thingy majiggers that add 20% to my generation.
    I was civil.....honest....until she hit me with the price then I kindly told her I'd researched their piece bit of kit and it was a complete waste of money, she then got a bit shirty so I told her to have sex and travel and not bother me again.
    Unluckily her number was withheld so I couldn't block her number with my CPR call blocker as I have a few friends who still insist on calling withheld

    Had the same visit myself today. As above no specifics or literature. Is it safe to say there is no miracle device that can increase my output by 25% like they are claiming?

    The only possible thing I can think of is an upgrade to a SolarEdge system, but 25% is unlikely, more like 10%, and only then if there is a little shading.

    Anything other than 'mucking about' with the panels, can't work, as there aren't enough losses between the panels and the TGM to give you a 25% increase. Most inverters are around 94%+ efficient (I have a small 92% model, plus 94% and 96% models), so no room there for 25%.

    If two people have had visits, but still can't work out what's going on, then it all starts to smell rather fishy ..... actually that ship sailed long ago.

    Might as well try to find out what it is, so have requested contact, got this:-

    Thanks a bunch for filling that out. It means a lot to us, just like you do! We really appreciate you giving us a moment of your time today. Thanks for being you.
    ...... seriously ...... ?

    They called me back today. Keep talking about a guarantee of 25% increase. Want me to spend 30 minutes talking to someone which I have declined. Definitely sounds like they are looking at the inverter claiming that's where the savings can be made.

    Have checked my inverter (Diehl 2100s) and I think it's about 94% efficient. I have no issues with shading. I'm struggling to see how they can improve output by more than few percentage points.

    So glad I found this thread. I too have had a doorstep caller followed by a phone call. As soon as the guy left my door I regretted giving him my number and, having had the phone call, I regret it even more. I love my solar panels (they're my contribution to the end of nuclear power!) but can't see any way that generation can increase by 25%. I expect they'll phone me back but I won't be accepting their offer.
