Understanding shading

Yes we do seem to have side tracked but I think this is what forums are for. Not only to advise but to air views and opinions in the hope that it educates.

As I've always said I'm open minded and that 12 month bill of just 1.25 pounds is very impressive, it is certainly better then I would have thought, and certainly it's better than the normal figures that are given, which I believe is just 125 pounds a year saving on an average bill. You seemed to have surpassed that by quite a margin, unless you annual bill was approx 130 pounds a year without the system.

In fact it is remarkable that in that year you have used perhaps only 16KWh from the supplier at what, is it now approx 8p for a kWh, and as you have a young family and all that entails, and during the harsh winter we had, I'm impressed.

I'm sorry to say Mark I do focus on OAP's and poorer members of our society because they are the ones who struggle to pay their bills,we all struggle to pay bills, but when more than 10% of an income is used on fuel bills it is classed as hardship, and a lot of those I highlight are in hardship, and that was before these Carbon Taxes were introduced. So yes I'm afraid I do resent the fact that these people have to contribute to the benefit of already wealthier parts of society.

But after your figures I'm even more confused on why FIT's are needed. Your system is an average size I believe and I understand that not all installations will be as efficient as yours as obvious factors will come into play. But even a system 50% less efficient would only need to draw approx 25KWh from the grid a year and that would cost just 2 pound a year in electricity bills, that surely is a fantastic incentive on it's own. Of course if you do have the plus of feeding back into the system you quite rightly should be paid for that and perhaps more than the 3p that is now given.

Again Mark I'm going to have to cede to the social scheme your going to hopfully start. I thought, wrongly that it was one of those that have been started where the install is done free of charge, but the companies claim the FIT and the tenant gets the saving on the electricity, though now after your figures if that produces a yearly bill for the tenant of below 10 pounds say that will be a wonderful saving.
Though a bit confused with the part that when you say " The cost will be on the value of the property, no different to what we do on private developments'. Is this a "Green loan" the tenant or the council/housing association will be taking out?

The only thing I have to pull you up on is I never said PV does not work. I only questioned the viablility of it working in the UK without the Tariffs. In my first post I mentioned that when the System is a large free standing type, that as the abilitiy to track the sun through the day for optimum yield, PV can produce good results well worth investing in. I'm just amazed that a static system in the UK of a very small size can yield as much, considering that for 4 months of the year our daylight hours can only average 8-9hrs never mind optimum sunlight
 
Can I point out the floors with sun tracking? Yes I do agree that they produce slightly more KWh's than a free standing system but they are just not economically viable. Tracking systems require power to run the motor that turns the array, moving parts = maintenance and more things to go wrong. The extra generation that a sun tracker would produce would not outweigh the costs of the power required to run it and the maintenance that it would require.

In the UK it is safe to assume that a 2kWp roof mounted or ground mounted PV system would produce roughly 1800kWh's per anum (obviously the majority of this generation occurs in the summer) if we take that example and apply the feed in tariffs to see how much it would earn in a year then we can see why PV is such a good option in the UK.

At the moment the FIT's state that for every 1 kWh generated the generator will be paid 41.3p regardless of whether it is used on site or exported back to the grid. 50% of the total generation will be paid at 3p per kWh.

so....

1800kWh * 41.3p = £743.40
900kWh (50% of total anual generation) * 3p = £27.00

so from FIT's alone the generator will recieve per anum £770.40

we then have to factor in the amount of kWh the generator will no longer be buying which is 1800kWh and multiply it by the cost of electricity which is roughly 12p per kWh at the moment

1800 * 12p = £216.00

add that to the FIT and the generator will save

£986.40 per year

and with 2kWp system costing roughly 10k to 12k the system will have paid for itself in roughly 10 years. The generator will then go on to continue earning this sum for a further 15 years, not to mention the fact that the FIT are linked to inflation so this will be likely to rise
 
Cheers MMCCX top post as you have finally given some figures which we can actually look at.

I think though that you have actually confirmed what I've been trying to say. I have never said that PV don't work I've always maintained that in the UK without the FIT PV is not a viable proposition.

Without the tariff the yield return will be £243 approx. With the install as you said approx 11k it would take you over 45 yrs to pay back.

Without these FIT the whole system will be unviable, and as I've tried to get through these FIT are a subsidy from the Carbon Taxes. These taxes have been realised by the electrical companies raising their tariffs and the biggest raise was on Key meters. The biggest users of those key meters are the poorer members of our society.

I'm sorry but this to me is an obscene situation. You have the poorest subsidising the the wealthiest as it is mainly people who have a disposable amount of cash ie 11k who can afford to put these systems up.

I honestly don't decry anyone for wanting to make a living. I personally could not work in this industry as it stands today. I could not justify making money from people who are not just struggling to pay their bills, but are having real hardship doing so, and having to sacfrifice others things to just pay them.
 
I think MMCCX has summed it up nicely.

And that is exactly how my electric bill for 12months was £1.25. I paid my supplier our normal DD payment but once I got the FITs cheques in, export tariff and reduction in purchased electricity it worked out I paid £1.25. My DD is now a nominal amount possible with or supplier £12 per month. I received a cheque for our substantial balance we had built up with our supplier after they sent THREE engineers out to see how we were fiddling the meter! Each time they noticed the panels on my roof before they came in! Funny really.

So why should I not take advantage of the scheme. I certainly do not agree that the poorest of society are paying for it, in fact I will go as far as saying they should be thanking me. Possibly an arrogant statement but I will explain:

Our current generation network is ageing, reliant on fossil fuels and in poor shape. MAJOR investment is required to upgrade and improve. Our Nuclear reactors are coming to the end of their live and need replacing. Investment in off shore wind turbines has been brisk to date but is slowly in decline due to lack of suitable sites remaining. The recent public release showing big farms off the coast still are not confirmed due to funding. Taking all this in to account work in the SSEG (Small scale embedded generator. Wind, Hydro, Biomass, PV etc) schemes are on the increase. Each one generating power and delivering surplus in to the grid. Every one putting a little back. Times these up across the nation and the generation infrastructure can be supported, aiding demand. The network is buying this power at 3p per unit and selling it on at what ever unit rate they like making profit off generation with no outlay for generation. This power is sold to each and every one of us without us even knowing it. The generated power I export from my PV array isn't lost its sold by EDF, EON, Scotish Power etc. If we need to invest in large scale new nuclear plants, alternative power stations what do you think the effect of this will be on our energy bills? I certainly believe that every new plant will indeed place a surcharge on our bills as well as increased unit costs and taxes. Hitting again those poorest in society. I can rest easy that what I export is used by our suppliers and sold on and if this means that investment in large scale plants is reduced, and I don't believe for one moment that investment will never be made, then I would say that this is reducing the need to increase the burden on our vulnerable society. So I am helping them rather than sticking my hand in their pocket.
 
There are many systems installed in the uk that are payed for by councils and housing developers that are on flats and houses that are lived in by the poorer section of society. Key meters are a horrible Idea and anyone who has one should ask to have them changed as the cost of them are just so exspensive.
These fits are ultimately being payed for by the general public by increasing the cost of a kWh but the increase in cost is marginal as the number of people with systems is far outweighed by the umber of people who don't have systems. So much so that we are talking about rises of a fraction of a penny
 
I'm of an age now where I think I have seen most everything but then along come you Mark and I realise that I haven't.

Your posts remind me of the old group the searchers, sure you won't remember them but they wrote.

In a world of own, which no one else can share
All our troubles seem far behind us
And I know that we will find our own peace of mind
When we live in that world of our own.

You have not I don't think even read what I wrote let alone comprehend the meaning of it. Your amazing £1.25 paid for a years electricity was down in the main to the FIT.

The whole crux of my argument is these tariffs that the system without them are about as much use as a chocolate fire guard. That without the tariffs you are whistling in the wind, poking a sausage up an alley, trying to kill an elephant with a feather or any other adage you can think of.

the fact of the matter is, also what you say, is that without the FIT no one would bother it wouldn't be worth it. But you seem to be missing the point of the feed in tariffs. The Fit's are in place to encourage people to buy more systems, the more people who purchase systems means that the demand for it goes up. As demand rises the industry is forced to streamline their production and ultimately make the products cheaper, modules will become more efficient and smaller, until one day the FIT's are no longer required, because eventually without them it will become viable and people will care!

But if the fit's are not there until this happens then we will continue to burn fossil fuels to power our generators to heat our homes to watch our TV's, to turn on the lights etc. Our inhabitable world is an extremely fragile ecosystem, by burning these fossil fuels we are ultimately damaging it and before you know it we will no longer have an inhabitable world! I know this sounds all a bit green and 'oh that will never happen' but I ask you, do you really want to find out?
 
Do you know what? I'm not even going to lower my self to a reply to that.

Good luck with what ever industry you're in and I hope it keeps you busy as what I do will keep me so!
