    Dragon's Den - Anybody know that Solar guy?

    Well, Ploughcroft are doing an installation on my roof as I write this. I'm a retired engineer and went into the technicalities, with a lot of help from posts from here, to generate a load of detailed questions. Their technical director answered all my questions spot on and showed me their...

    Sanyo HIT-H250E01 or HIT-N240SE10

    I'll try that soon as I can, but currently on a dial up connection in rural France so its not practicable.

    Sanyo HIT-H250E01 or HIT-N240SE10

    I can fit 16 Sanyo panels (just) onto the available roof area so can get close to the 4Kw max. for the best FIT. As I understand it the 2 latest Sanyo panels are the HIT-H250E01 or HIT-N240SE10. I'm being told by my preferred installer that quite apart from the cost being less for the 240, its...

    What is your preferred method of getting your DC cables into the roof void

    He didin't even look inside the house - just said he'd run DC over the tiles and down the house side. Take your pount on the ethernet though

    What is your preferred method of getting your DC cables into the roof void

    No, there's a simple 'invisible' route internally where I ran ethernet so I think its just 'quick in and out'

    What is your preferred method of getting your DC cables into the roof void

    One of the companies I had in to quote wants to route the DC cables under the array (above the tiles) and down the outside wall then through the garage to the main CU, connecting in using an unused way on an existing RCD. Quite apart from the aethetics I'd never consider this a professional way...

    A Basic Unanswered Question but fundimental to a householder

    All makes sense now. Hate not quite understanding things, especially when there's so much money involved. Thanks for the enlightenment. PS Yes, Worcester, I'm ok on the significance of the 3.68kWp value. Thanks again, guys.

    A Basic Unanswered Question but fundimental to a householder

    So taking what Spinlondon has said, and going back to my 2 tank analogy - the second being the big one (grid). Where the grid differs is that, unlike the PV output, it does have more than one exit (other consumers). As a result the property takes the PV power preferentially up to the output of...

    A Basic Unanswered Question but fundimental to a householder

    None of the PV companies I've dealt with so far has been able to explain what, to me, is a basic question. In a property with a grid connection and a PV installation what ensures that the energy from the array is used preferentially to that coming through the utility meter? Reverting to the (I...

    Best Fixing System for Exposed Location

    Good advice SRE. I've come to the same conclusions - am staying local and ensuring I'm speaking with the specialists in the companies, not just the sales guy. I'll take a look at SEN SOL

    Best Fixing System for Exposed Location

    I've tried hard to avoid the guys 'graduating' from d'glazing but none of the 5 companies looked in the loft, trusting to ground measurements, tile counting and Google earth to give me a quotation. Of course this is the unique problem with PV - there is electrical specialism and roofing...

    Best Fixing System for Exposed Location

    Thanks, Worcester, for the solid advice. I'll be interested to see what my 2 shortlisted contractors have to say, and whether it comes close. Especially as one is a roofing company that does accreditation of solar installers.

    Best Fixing System for Exposed Location

    I'm considering a Solar PV system on a property in an exposed location in the Pennines. We've had regular instances of tiles being lifted and displaced on our (concrete tile) roof by the winds we get here so a critical part of the installation is ensuring the panels dont get twisted, or ripped...
