    Brexit court defeat for UK government

    There were many contradictory claims and statements made in the campaign, many argued that we could leave the EU and still either be in the common market, have access to the common market or be part of a Europe wide tariff free, free trade area. They also variously claimed that none of the...

    Brexit court defeat for UK government

    I find it a little odd to see those who a few months ago were no doubt banging on about bringing sovereignty back, and the undemocratic nature of the EU now frothing at the mouth about the notion that the UK's democratically elected representatives (at least) should have a vote on the...

    4.57Kw PV with a 4Kw inverter. Inverter too small?

    yes it's a normal set up. Panels are rated under standard test conditions at 25degreesC and 1000W/m2 light, in full sunlight they usually reduce efficiency by around 0.45% per degree above this, so in full sun would be expected to peak at least 10% below their nominal rating due to temperature...

    Problems with Series/ Parallel strings not adding ampage.

    if it's dual MPPT inverter then it may well work on one side, and if you've got 2 strings the right way round, 1 the wrong way around then this would end up with it looking to the inverter as if it's got a single positive string. I've heard too many electricians tell me it's definitely not...

    Problems with Series/ Parallel strings not adding ampage.

    you've probably wired several of the strings in reverse polarity. The answer to these types of questions is usually reverse polarity, I'd triple check that before doing anything else. I know it sounds basic, but it happens to the best of us, so it's always the first thing I triple check even...

    Solar PV Module characteristics

    all depends on the sunlight levels. If in full sun perpendicular to the panel then you've got a problem, but that's unlikely to be the case in november.

    Qualifications challenged at MCS Renewal ?

    it's nuts and totally against what was intended - the experienced worker route was specifically intended to ensure that those who had been working in the industry for a long period of time did not need to go and do some pointless 3 day course that they'd be perfectly capable of leading. Had a...

    Pv install

    the v phase VO unit can only handle something like 16 or 20A, which will be why only certain parts of the system will run through it. tbh you could probably rip it out for all the good it will probably be doing..... ;)

    EPC New Build

    yes that's pretty much it - we don't connect the final wire into the inverter just to be on the safe side with the EPC assessor, so it's clearly not commissioned. royal pain in the rear end.

    Tesla Solar Roof

    not to put a dampener on it or anything, but those sorts of solar tiles have been tried before, but were discontinued because the lamination at the edges wasn't robust and broke down after a few years in the elements with no frame to hold it together. I see no reason to think that tesla will...

    Insured Warranties Not Paying Out?

    Last I checked there was a £500 threshold, below which the customer doesn't need multiple quotes for the work. Though this may have changed.

    Amending an mcs cert

    lol - go on then, what was the price? Back in the day when it was possible to make decent money installing solar without ripping people off. :(

    Amending an mcs cert

    I think as the installer you should be able to do that, unless MCS have disabled that for older certs in one of their portal updates.

    MCS Commissioning date - amended?

    oops. These new rules are a bit of a nightmare, particularly with new builds. It's so easy to make this mistake. Unfortunately I don't think there's any way of changing the MCS cert date.

    Segen - Solar Equity Release

    Invertor replacements: - Invertors are replaced every 5-7 years This bit's hopefully rubbish though, we've been factoring one replacement within the 20 year FIT period based on manufacturers statements and their warranty extension costs.

    Segen - Solar Equity Release

    I've looked into this, and tbh we're thinking about sounding out. previous customers about it as there will be some who's circumstances have changed and they're more in need of equity release now than the longer term payback. I think it will also work for people who're wanting to move house but...

    what's it tripping? RCD or MCB?

    Solor PV grants/schemes

    finance is never free, the costs of it will be paid somewhere in the bill, probably by jacking up the initial cost to silly levels. Get a sensible quote, and arrange your own finance if you're in a position to do so - if you're not then you're probably also not in a position where taking on...
