    Solar Panels 5th Oct 17 at 2:10 PM
    So ive just had my 1st salesman round about installing Panels on my House and was Quoted £10550 1 of things he kept saying was a "Voltage Optimiser" would save me close to £300 a year, i had never heard of these and when checking online this seems to be very far fetched , He quoted me for 6 panels , Volt Optimiser , and a water heater (so any extra power goes to heating water) and installation. Has the panels and equipment come on that much that these volt optimiser are that good . I live in North Essex and my roof is facing 100 degrees has no shading so gets the sun up too around 3 pm , Im not to worried about selling my extra energy back this is more about saving money by using the solar power lowering my bills as we are an all electric house , i cant help but think that this is a big outlay for not a big saving . HELP please

    This is a nonsense seller. £10k would get you a 10kw system, which is about 3 times the size necessary for a typical house.

    You dont need a boiler to store water. The small amount you could save is just not worth the cost.

    Voltage optimisation will not save you £300 per year, unless you are consuming thousands per month in electricity.

    Hiya Salty, that's a scary quote. Actually it's terrifying.

    6 panels suggests to me it's a 1.5kWp system. You really want to aim for £6k or less for a 4kWp system.

    This may sound silly, but I'm actually quite angry reading that, it's disgusting, so good on you for seeking advice. None of us sell PV, we are just PV'ers so are happy to help out anyone looking to dip their toes in too.

    Have a read of the FAQ's as Eric suggested (see link in my signature).

    Also you may be interested in this recent thread, just because it throws up some similar issues, and saves us repeating some of the info.

    To put that price in perspective, it's a few hundred more than I paid in total for my two systems which give me 5.25kWp and the more expensive immerSUN diverter and which were installed in June 2013 and March 2014. And doing two separate installs comes at a premium (more scaffolding costs, travel, labour etc).

    I would send this firm packing (don't even bother haggling on price) and get quotes from elsewhere.

    You might also want to browse yougen.co.uk which I found helpful when I was setting out and before I found this forum, which gives people really sound advice. They do have comments on installers, though how up to date they are is not known.

    As others say, ask, ask, ask...

    Hi

    Give them a bell and ask them to confirm the TIC (total installed capacity) of the 6 panels& what make of battery storage they've quoted for ...

    That kind of price looks like a package deal for a 4kWp (12-16 panel) PV system plus a Tesla Powerwall2!

    Anyway, as already mentioned elsewhere, if you're on domestic supply & metering then a VO system is pretty useless at saving you money, but pretty handy for the installer to making off with your savings!

    Here's my take on your quote
    So ive just had my 1st salesman round about installing Panels on my House and was Quoted £10550(robbing bar steward) 1 of things he kept saying was a "Voltage Optimiser" would save me close to £300 a year(waste of time), i had never heard of these and when checking online this seems to be very far fetched(you're not wrong there) , He quoted me for 6 panels(Is your roof that small?) , Volt Optimiser(forget it) , and a water heater (so any extra power goes to heating water) and installation. Has the panels and equipment come on that much that these volt optimiser are that good(NO) . I live in North Essex and my roof is facing 100 degrees has no shading so gets the sun up too around 3 pm , Im not to worried about selling my extra energy back this is more about saving money by using the solar power lowering my bills as we are an all electric house , i cant help but think that this is a big outlay for not a big saving . HELP please

    Start again by getting several (normal) quotes
    Post the details on here...ie, system size, make of inverter and estimated generation and even roof size as then someone on here would be able to estimate how big a system you could get for your bucks.
    Don't post any company details so as not to get them picked up by search engines.
    There's plenty of good folk on here who'll stear you in the right direction
