Especially when you are criticizing the piece as being a sales pitch, you would absolutely know that it would be included.
And now in your attempt to slither away, you've written that you "included all three factors" after I pointed out that you had falsified your "analysis" by omitting the FIT.
Here is that paragraph and your claims:
... fewer than half of non-apartment dwellings have EPCs high enough to qualify for that rate. Most people would instead get 6.85 p/KWh.
Maybe; but if we are going to play the supposition game about what people are going to qualify for, then perhaps those who elect to go for the solar purchase will also investigate and sign up for the energy efficiency program that the Conservative's have tried to kill for the nuclear lobby. In other words, the unintended consequence could just as easily be a '2fer' with interest in low cost solar driving both solar purchases AND energy efficiency retrofits. They reference the average homeowner, so again, given your track record of playing fast and loose with the truth (as documented here), I'd need to see something solid to show that the average homeowner in Britain has a energy efficiency rating lower than D.
Here's the meat of your claim about including "all three factors".
And I'm sure you also just forgot to include any estimate of the impact of the export tariff being only 4.64 p/kwh (rather than the 16 p that I used in the calculation). Solar insolation in the UK is 6-7 times greater in summer than in winter... so for some months you aren't saving (much of) anything at all, and in others you're producing more than you can use and saving 4.64p instead of the 16p that offsetting your own usage would save.
Now, compare the
either/or dichotomy you've crafted with the two quotes I provided:
...you will be paid 15.44p/kWh for the electricity generated by your panels (from April 2013), irrespective of whether you use this energy yourself, or export it to the electricity network. In addition you will be paid 4.5p per KWh for any electricity you don’t use yourself and, therefore, export to the network...
And
Generation tariff: your energy supplier will pay you a set rate for each unit (or kWh) of electricity you generate. Once your system has been registered, the tariff levels are guaranteed for the period of the tariff (up to 20 years) and are index-linked.
Export tariff: you will get a further 4.64p/kWh from your energy supplier for each unit you export back to the electricity grid, so you can sell any electricity you generate but don't use yourself. This rate is the same for all technologies. At some stage smart meters will be installed to measure what you export, but until then it is estimated as being 50% of the electricity you generate (only systems above 30kWp need to have an export meter fitted, and a domestic system is unlikely to be that big).
Energy bill savings: you will be making savings on your electricity bills because generating electricity to power your appliances means you don’t have to buy as much electricity from your energy supplier. The amount you save will vary depending how much of the electricity you use on site.
Now lets rewrite the first quote using terms instead of numbers:
...you will be paid
the generation tariff for the electricity generated by your panels ... irrespective of whether you use this energy yourself, or export it to the electricity network.
In addition you will be
the export tariff for any electricity you don’t use yourself and, therefore, export to the network...
So the formula is
Income Stream = Energy Bill Savings + Generation Tariff for 100% of production + Export Tariff for 50% of production*
Not.....
How in the hell would you write your so called calculations so that they are legible and comprehensible?
...and I'm sure you also just forgot to include any estimate of the impact of the export tariff being only 4.64 p/kwh (rather than the 16 p that I used in the calculation). Solar insolation in the UK is 6-7 times greater in summer than in winter... so for some months you aren't saving (much of) anything at all, and in others you're producing more than you can use and saving 4.64p instead of the 16p that offsetting your own usage would save.
Your words and numbers throughout look like the kind of presentation any shady salesperson would make who is intent on hiding relevant information from the consumer.
So I close by repeating my previous statement:
"Bottom line? Your calculations as one of "those nuclear salesmen" were/are far less credible than those offered by "those solar salesmen". "
