Well it's a bit more overcast today, but still. Man came about the solar panels, recons I can get 12 on a just about directly south facing roof and they should produce 4-5000KWh of electricity. The thing I found puzzling was they use the information on your last energy statement and for some inexplicable reason they've estimated my electric consumption at just over 600KWh annually whereas I've actually use just under 1500KWh in the year I've been with them, would love to know how they come up with that, I suspect it's some computer generated number because even the average primary school kid could add the numbers together and come up with the right answer, so he worked the savings out on that but also the 18p unit rate rather than the 30p it will be in a week or so. Anyway upshot is it should drastically reduce my energy bill over the year.
I seem to remember that they have to use data based on specific requirement
ratehr than using what data they want
because before that some dodgy companies used data that made them look better - rather than data with a connection to reality
so they made companies use the same thing
which works for some - but it rubbish to others
In our case - we have just had a phone call back from our installer from several years ago
I asked them if it was possible to change our system
a) to allow us to use the batteries in the case of a power cut/failure/destruction
apparently this require a "gateway" so he is letting us know the price
b) to increase battery storage so we can get more advantage from the sun (not the newspaper) and from off-peak charging tariffs
c) add some extra panels to the front - which is pretty North West facing but has clear sight of the sun even when it is low down
apparently the batteries are available - but his comment was that he might get lucky but it might be easier to find The Holy Grail!!!
still - he is sending us a price
