Renewables: "talking 'bout my generation"

And talking about input to the thread, is there any reason why this post was deemed unworthy of comment (from anyone)?

Thanks Kernel. I had previously missed it (so much for the theory that I'm glued to MSE 24/7 :rotfl: ) but have now responded.

No idea why nobody else noticed.

No, the IH does not draw same current !

The parameter about the IH that is fixed is its resistance.

Current drawn is calculated from Voltage divided by Resistance (thanks Herr Ohm)

Simple algebra dictates that power is therefore given by voltage-squared divided by resistance and it therefore follows that halving voltage will quarter the power consumption (but plus a small allowance for transformer losses).

Thanks, I didn't know any of the above, so there's nothing simple for me about the last sentence!
I can see that the 'power drawn' bit is measured in watts, but how is the 'current drawn' measured if not in amps?
I'm presuming a suitably sized resistor placed inline somewhere in the circuit would have the desired effect, so why is this not a viable alternative?

Google Chemtrails , That will explain all the mist we get constantly and why we never seem to have the clear skies that we used to , Chemtrails are more commonly referred to as SRM (Solar Radiation Management) or Geo Engineering.

Great to see people generating there own energy BTW keep it up , has anyone dabbled with making their own solar panels?

Current drawn is indeed measured in amps.

A large resistor would indeed reduce power to IH

Let's make it simple and assume the new resistor has same resistance as the IH.

Fit it in series then resistance doubles. Voltage stays the same so current halves. Voltage still same so power drawn by system also halves so you'd get a 1500W system

But power drawn by system is in two parts - old IH and new resistor - and I've defined them as equal. Hence IH now using quarter of initial power (750 W - just as with transformer) but the resistor is also using quarter of initial power and that 750W is pumped out into Kernel''s bathroom (where it might do a little good) or my basement (where it won't).

If the object was to use as much free power as possible then the resistor approach might have some merit - but that would mean that it could run less often than my system (I'm making assumption that there are occasions when I've got 750W spare but not 1500W) so water wouldn't get as hot.

If of course you put new resistor in parallel with IH, IH would continue to draw 3kW and so would the resistor. I don't often have 6kW 'spare' from my 4 kW system !

No, we have no room left on our rooves to put them

Actually, I've got plenty of room left on my roof - but if I built my own I wouldn't get any FIT payments for them and they still haven't got to the point where I feel I could gain enough electricity from them to justify the (admittedly modest) outlay.

And of course someone would be sure to come around and demand to verify I wasn't feeding their output through my TGM.

They are better if you just want to have a small electricity set up in your shed or something , I made one that works fine for charging my drills and stuff via a 12v battery and a controller / 400w inverter , its a learning curve but was well happy when it started putting out the power , building a waterproof and not too shiny case is the hardest bit , soldering the cells is a bit of a sod , they are so thin you wouldn't believe it!!

18.37 kWh so far today (but still generating 200W).

Definitely ahead of pvgis for June now next 5 days will be a bonus.

Just over 6 O's or 24kWh up to now today:rotfl:
Also passed June PVGIS and still generating over 350W at 20.15:j

I don't know what my monthly figures are. I do know though that my ESE should do 639kWh for the last quarter(01/04-30/06) and i'm currently on 679kWh(+40 on the quarter:j)

My SSW with late shading issue is on 625kWh for the quarter but should do 659kWh(5 days to go so still do-able:o)

I managed 19kWh today(4.75 O's) and am still generating about 140W. Wifes done 4 loads of washing,1 x drier and dishwasher on for good measure. And TV on ALL day for the kids:eek:
