    So if me and Mr Kandy shelled out say £15,£16,£17,000 grand for solar panels to fit on the South facing wall of our garage how many years will it take to recoup the money spent out in the first place on the panels with the revenue that we are going to generate from them and what they give us back?

    Plus doesn't the Invertor have to be replaced after a number of years which will be more expense:scratch:

    I can't see the builders putting Solar panels onto new builds in the near future because though they could do a deal and get the panels/fitting done quiet cheaply they will still add on thousands of pounds to the cost of the build to make even more profit and the price that the houses cost anyway prevents a lot of youngsters getting on the housing ladder in the first place.:sad:

      The answer with solar panels might come when someone invents a roof covering that is one big solar panel instead of putting on tiles or slates.

      Elon Musk (Tesla) has withdrawn his main storage cell due to the economics not stacking up but I've no doubt they'll be back with another type of electricity storage.

      The ultimate answer for "free" power is tidal. The tide goes in and out twice a day but the wind doesn't always blow nor the sun always shine. Their answer in tidal power is a "screw" device inside a tube instead of "blades" twirling around. (Please send the royalties to me.) :) :)

        Hiya Kandy :blue thumb:

        I've just had a quick look online. The first one I came across quoted around £6,000 for a 4kw system. Just sayin' :)

          @Kandy
          Just a quick reply as I'm busy:-
          You can get a 4kw system for under £5,000 and the builders can fit it on new builds for no more than £1,500 - possibly less than that if it's done in quantity. A member of the public, if they're handy, can do it for themselves for under £2,000. You can get inverters for about £800 and they should last at least 5 years. I've based that period on the fact that ours is guaranteed for 5 years and they wouldn't give that sort of guarantee if they thought it wouldn't last that long.

          On the Feed In Tariff that I receive (I don't know what the current :snork: rate is but once you're on the system you get the same rate + inflation for a guaranteed 25 years), plus the savings on the electricity that I use and the price I paid for the system I shall get my money back in just over five years. Then it's a good profit from then onwards. I use quite a lot of electricity but if you don't use as much it could take up to seven years to recoup the outlay.

            We have just got back from a quick trip out so only just seen both of your replies,Thank You @Freddy and @shiney.

            Some friends of ours in the village have sixteen panels on their South facing roof which they got four years ago and paid £16,000 for them so I am not sure if the price of them have come down over the last few years:scratch: The hubby was saying that since they have had them installed the feed in tarrif (not sure if that is the correct term:)) has come down so they don't get as much return on them now like they did when they had them installed:smile:

            The only area we have which is South facing is the end of the garage wall that faces South so that is the only bit that would generate enough power to the panels.

            As we are on an Article4 restriction I couldn't see us ever getting planning permission to install any solar panels because from what we have found out from others on the same Article4 directive we can't even have plastic Windows as they can be seen from the road even though the house downpipes are plastic plus part of the window frame above the wood frames is plastic so there would be no way that we could have solar panels on our nice slate looking roof:snorky:

            I've never been quite sure of the logic of solar electric panels on a house roof.

            Most of the energy consumption in a typical household goes to heating water. Water is actually very energy intensive to heat. So if you're going for solar, why not solar water heating? Simpler technology and less conversation losses.

            The feed In Tariff was slashed in January 2016, to be phased out totally later this year.

                If they paid £16,000 then they were 'done' by the installers!
                Also, I think they are not telling you correctly as the Feed In Tariff that you receive when having them installed is guaranteed never to reduce during the 25 year period.

                My cousin has them on an East facing roof and he gets only 10% less electricity than we do. The reason being he gets his solar power a lot earlier in the morning than we do. From about 1 hour in the spring, quickly rising to nearly three hours in the summer and dropping off again in autumn.

                We may not be a typical household but we use a considerable amount more electricity for things other than heating water. We use almost 3,000kWh per year of our solar production. :blue thumb:

                In all seriousness, our gas usage is way lower that our electricity usage, which
                last year was 3,600kw. If I'm correct, that equates to just under 10kw a day. @shiney, let's say I went for a 4kw system, does that necessarily mean that I would have a 6kw deficit?

                You will not get 4kw from a 4kw system.

                Yes, I realise that. I'm just using those numbers to make it simple.

                @Freddy

                4kWh system is unlikely to produce that amount except in exceptional circumstance. I have a record of having reached 3.93kWh (my system records the output every 10 minutes).

                But you're probably mistaking the amount of 4kW as meaning per day. It's the, almost, maximum that you can produce per hour. So, in theory, you can over produce by a considerable amount in a good day.

                Today, very overcast, we have so far produced 5.4kWh but last Friday, a nice sunny day, we produced 26.8kWh.

                In the winter you will produce less and in the summer a lot more.

                As we have a fairly high consumption of electricity (home all day, a lot of underfloor heating, lights and equipment on and washing machine and tumble dryer going a lot, propagator and probably a lot of other things - just remembered airconditioning on hot days) we still use a lot of electricity from the grid in the winter, early spring and late autumn but over produce quite a bit in the summer.

                  Ahh, of course, thanks for putting me straight. So, on the face of it, it's not a bad system. Just the initial outlay that will put many off. I'll have to investigate further :blue thumb:

                  It's not a very good investment with the ending of the Feed In Tariff.
