Choice of intelligent switches ?

Yes you are right BUT its so minor though in comparison to the FIT tariff you achieve ( im on the original 43p tariff ) and the cost of your gas or electric to heat the water, especially if you use a lot !

For example:- even though I earned in excess on £ 1,000 last year my earnings for EXPORT were approx - a mere £ 36.23

So no reason at all NOT to purchase and fit a proportional immersion device such as the "Solar Immersion" ASAP, IMO

Hi

A quick question ....What's the spec/size of the system which is driving your proportional immersion unit. ?

One thing to bear in mind with the ImmerSUN type units...

Depending on time of year and excess being generated your heating may continue to run instead of stopping to heat water as hot water usually has priority. Therefore perhaps no real difference in useage.

Obviously dependant on setup but I think it's a plus.

But, as far as I can see, this has no bearing on anything. The 'export' payment is simply a calculated proportion of the generation, so all you can say is that your earnings were £1,036.23 - it is simply part of the FIT payment. Your real exports are something completely different.

The warning is:
If the first generation of PV installations were to get a realistic price, for a measured number of exported kWh ("units"), then the clever switch investment would not be so profitable.

I cannot see that happening any time soon.

A mere 2.88KW based system with a genral run of the mill 3kw immersion heater element fitted by the builders of the house 15yrs ago

Arrr - I see what you mean.....

Nearly but I dont I added all the actual payments for last year - it was a quick add up .......... plus did you allow for change in tariff rate due to rate increase etc ??

Anyway - YES ......before fitment of said device our actual export was between 30-45%

Since fitment of the device its now virtually NIL, however in the next 4mths that is bound to change as the PV system hopefully will be producing far more than we can either utilise via our newly accustomed ways and via this newly fitted device.

So you can now understand atm, we not just normally benefit from the initial generation tariff, we also use the free electric and then get paid a 50% tarriff based on electric we dont even supply to the grid - so a win win win situation atm

But I cant tell you one thing - most of the time our meter is stopped dead and we only use electric during the evening and at night.

The real saving we have in our situation is that with this device fitted - we dont have any energy costs providing hot water, which I calculate at approx £ 80 p/a roughly using GCH to heat the HWC, the rest is a bonus......

But the clever ppl who either use electric when generated or use home automation devices to use generated electric during the day whilst at work gain double fold as they get paid for generation, and use that electric free of charge to run white goods and/or use with immersion devices to heat their water tanks

I'm not bothered about the export tariff as I get in real terms very little in return from this using the governments 50% calculation as its so very little.

However I am bothered about how much it costs me to heat the water in my hot water cylinder and this is where the REAL cost saving occurs now with the Solar Immersion device as I have now have NO costs whatsoever heating water in the cylinder to boiling hot temps - the GCH is now turned off as teh device supplies all the pipping hot water I need... even when its fairly cloudy. Not had a day so far when the wife hasnt complained that the water is too hot !!!

Is that more informative for you ??


The arguement you are trying to adopt is if you got paid for all your export at 3p you maybe better off - BUT you wont against paying for energy at either 12p in the first place. That fee would have to increase alot to come anywhere near my situation now using a Solar Immersion device ???

Good guess btw - hope you didnt spend too much time working that out, as I could of helped you alot by stating the system produced 2.4mwh last year

The real difficulty now to be honest is finding a suitable and cost effective device that can measure the true consumption by the household as well as tells us what been imported and exported as we have currents flying in all directions now ( due mainly to the Henley Block connection ) - can you suggest any really good cheap CT based monitors for this kind of calculations as my Envir Eon isnt capable to do this now which links up to the PVO site

bought a couple of weeks ago and decided to fit it today... price gone down since purchase and having the power off means I have missed out on about 6 KW of generation.... £30 down already LOL
