    my 2 cents
    my hele huis is met led ligte uitgerus 100w in totaal
    geyser het n paneel op wat water warm maak
    krag rekining n maand met met water riool en vullis kom uit op n max van 450.00
    ons kook elke dag op gewone oond
    het 3 yskaste wat hardloop 24/7
    beste oplosing om om die beurt krag te kom is n genarator met change over switch
    prys op change over switch is R750 vir 2pole 60amp en R1300.00 vir 4 pole 60 amp
    kabel werk verskil in prys hang af hoe ver jou genset staan van db van af 800.00
    twee pilot liggies om vir jou tewys of statsraad krag aan is R130.00
    diesel genarator 6.25kv oop tipe is 14000.00
    duurste is maar jou genset maar daar is nog goedkoper opsies ook
    die inverter opsie is redelik duur net die inverter kos amper r18000.00 sonder die batterye

    bygese dit is wat dit sal kos om dit self te doen
    al extra koste is dan die coc en dit is vanaf r250.00

    First, how much light to you need

    I have 2 10w floods, and it lights up the whole yard!

    Now me, I have an inverter connected in such a way that should the power just dissapear, a relay falls out, disconnecting the mains from the light circuit, turns on the inverter, and connects the inverter to the lights.

    If the electricity arrives again, the relay comes on, and reverses the process. I have a charger charging 4 deep cycle batteries.

    Now the whole setup could be changed.... the inverter will drop out at 10.9 volt, so I can charge the batteries with solar, and change the relay to first supply the lights from the inverter, but here is the thing....

    With all the lights I have installed, all of them on at once the circuit uses less than 300 watt....

    Rechecked.... my lights circuits is 140watt for both.

    nicely done a few years ago it would have been 10000w

    Sure Pierre every situation is different, all I can relay is personal experience. Swambo and I decided some years ago to move away from bulk shopping, especially meat, no more hind quarter or whole lamb.
    Switched off the freezer and although prices are a few bucks more per kilo I am really happy with the decision, less spoiled or freezer burn throw away, fresher and healthier food, just the cuts we really want and we certainly cook less meat than before.
    Same story with vegetables and salad ingredients, we try to keep the fridge as empty as possible. But as you correctly said, you do need the shops to be close by and accessible.
    4x4 less.

    Everything is a hammer.
    Unless it is a screw driver.

    Then it it a chisel.

    Very interesting...

    Got the Solar geyser.
    Got the LED lights everywhere
    Got the Gas stove (need to install it though)

    The last 4 big user are a lot more difficult to solve.
    Fridge
    Freezer
    Washing machine
    Dish washer (ok ok you can do it your selves)


    Any average consumption figurers for some of the other usual suspects in the house?
    PC's
    Laptop's
    LED TV (mine is 126 Watt its actually pretty low)
    DSTV
    Electric fence
    Kettle (Will be sorted as soon as the new stove is in)
    Hair dryer (Gebruik 'n knipper )
    Microwave


    Will be keeping an keen eye on this thread

    Cheers

    Fridge
    Freezer - ONE larger unit uses LESS power than two smaller units
    Washing machine - modern units are MUCH more water and power efficient
    Dish washer (ok ok you can do it your selves)

    PC's - the problem is not using the PC, but the modern home where 3 or 4 PC's are idling away for no real reason ....
    Laptop's - as above
    LED TV (mine is 126 Watt its actually pretty low) - days gone by there was ONE tv in a house, now there is at least one in each bedroom and a couple more in the house ... many standing ON with nobody in the room
    DSTV
    Electric fence
    Kettle (Will be sorted as soon as the new stove is in) - kettle may just more energy efficient than a stove ....
    Hair dryer (Gebruik 'n knipper )
    Microwave - at least this only use power when you USE it


    Will be keeping an keen eye on this thread

    dont underestimate the net effect of a number of lights left on for long hours, for no real reason.

    My biggest worry about all this is my coffee machine with the 1.8kW boiler.

    That's important. Very important. Then we must consider the beer fridge.

    The washing machines and stuff are bourgeois luxuries. No power for them ...

    see how it all boils down to "user behaviour" ?


    ALL it takes to save electricity - boil 245ml of water in an energy efficent kettle, add some RICOFFEE and there you go.

    Priorities..... in this order, coffee, beer, safety (some form of light)....


    Edit: might have to rethink this....

    Safety, coffee, beer.....

    the attachment in Post 6 explains the process.

    from a legal perspective - the SAME Regulations apply across SA. Strange how some choose to ignore it ..... NOTE the ones where Eskom DONT "have to" buy back you power ... LOTS of speculation doing the rounds at the moment ! The attached document (post 6) is one of the only ones where a Municipality is upfront about the FACTS, not some PR exercise.


    from a financial perspective - eskom sells the power to larger municipalities at a LOW tariff. The municipalities have to distribute it and fund the upkeep of this infrastructure. So it COSTS the municipality money to get the power to your home - thus the higher unit rate.

    Now you generate power - WHY should they pay you 1c more than what they pay eskom ??

    THIS is why the payback periods DONT make any sense ..... as most people will be using a second bond to finance this little exercise add interest to the equation and there is hardly any break even point.



    fact is that this model is NOT in favour of the guy at home that wants to generate 10kW/h during the to run his fridge and tv at night !!


    AND, any other municipality that makes this a 1:1 CLEARLY has not done their homework !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!




    we have done the maths a couple of times - mathematically you CANT justify these systems !!

    the only reason you go this route is to be independant, either fully or partially
    One teeny weeny point you are missing in your purely commercial breakdown of what is commercially viable for municipalities, and why they may not buy back electricity.

    As a municipality they have a legal and moral commitment to reduce their green house gas emissions.

    Right now, paying you the price for electricity that they sell it to you at is BY FAR THE CHEAPEST OPTION available to them to reduce there emissions and achieve local, regional, national and ultimately international legislated targets.

    To them reversible meters are the answer. Sorting out the technical and safety legislation, and the complicated compliance issues is the hurdle.

    Im with you there! Those piss weak good for nothing "silent" inverter type generators is terrible.

    The 2kva one we have at work is incapable of running a 1kw impact dril..... without load

    It will become a reality.

    Just like Eksdom subsidies for water based, spit, Solar Systems. Identical situation from a commercial point of view.
