    I am busy with a project (cant talk too much about it...due t privacy consent etc ) what i can tell you is people sure know how to milk the tax and rate payer.

    Do the maths ...if you have a 3000 amp power supply from a transformer... the estimate done by the electrical consulting firm ...then they add in 2000 amps of solar power... at peak... but the max load consumed by all your tenants is 350 amps during peaks hours... what would the return on invest be? ... Then offer a solution... the solution is to upgrade the power to the tenants who dont require the additional power but you can make another R10 mil in revenue installing an upgraded system... just because nobody is auditing your services.

    Electric cars are no different to CFL and led lighting - its just an excuse to create another new replacement market of obsolescent products that really don't have much value when one looks at them on a cradle to grave basis. All that they do is shift the energy used to the manufacturer and thus the consumer is duped into believing that this "new" technology is the answer to the world's problems.

    The bottom line is that the problem with transportation lies in our notion that each and every person on this planet need 1 ton of "new" technology to lug them around.....unless we move to remote offices and mass transportation we are just going around in circles feeding the obsolescent wasteful economy of "new tech is better"
    I dont agree... electric cars are already here... the catch is the cost ... just like LED TVs ...they were so expensive only the rich and famous could afford them... i own 2 LED TV's and 4 monitors ...soon to be upgraded to one in each room of the house...because they have become so affordable... (free if the truck stops long enough for it be looted)

    I take it you dont follow DIY electric cars etc on youtube... the reality is that those old medical batteries which were being dumped after period of time ...where a huge disposal issue... since the DIY revolution... those packs are now on a waiting list... people paying upfront for them to secure the next batch... I am even considering getting a spot weld to link batteries and building battery banks in my workshop... you can buy plastic modules to link which dont require a spot welder... anyway my point... it is already happening.

    A couple years ago the 1650 battery were the one to get ...now you can get batteries which look like a flat foil pack... which is being used to install in the chassis of the car... take your old man blinkers off and see what the future holds... i can see parking bays having a section of the floor being the non contact charge station ...so you drive in ...tickets and boom will be a thing of the past ... you will park in a bay which will top up your power and debted from your account... as they mention ...these cars will be online 24/7 ..there will no keys...the car will detect your presence and allow you to drive it ...in fact i dont even think people will own a cars.

    Us old folk need to get out more and take not of what is happening around us... another example is cctv ...home automation etc ... every man and his dog has cctv and home automation... why because it has become affordable.

    Eskom will never recover from the debt ...it will get milked for as long as the people throw many at it ...eventually it will be replaced by a private institution... just like telkom... it was a sinking ship ... telkom land lines and adsl are already being phased out completely ... the new super powers have installed new fibre networks in the majority of SA... paying their dues for now...watch carefully what happens in the future.

In Durban the infrastructure availability fee for a single phase residence if I put in rooftop PV at my house is higher than my current electricity bill! It is insanity. The only financially viable installations in Durban at the moment are 3 phase installations which pull a large load... So I'll put in solar for my geyser at my house (which doesn't attract a punitive tariff (yet)) and stop there at the moment.

    And yes, Eskom is our greatest obstacle to widespread electric car adoption. There is absolutely no way that we have the required capacity from the existing grid, even mindful of the development plan, for a rapid switch from fossil fuel fired engines to electric for our national automobile fleet.

    The significance of the Eskom financial disaster cannot be overstated.
    I agree with regards to the PV generation... they cant afford to let us go solar... think about it ...back when load shedding started ...the thought of having to invest in a generator was just too expensive ...load shedding came into affect ... within days we were unloading R100 000 generators by the dozen... to add salt to the wound ...generator prices doubled and some withing a days... we couldnt even bring them in fast enough to keep up with the demand... a lot of people lost a lot of many back then... we had container loads of generators sitting in the harbour waiting to be cleared suddenly the load stopped ...just like that ... thank goodness it was other peoples money ... eskom cannot afford to allow us to go solar ...The only thing holding people back from covering their roof in solar is the "industrialization tarriff".

    A few things with regards to solar

    Covering your roof ... saves you having to fill it with thermal insulation...creating a cooler roof space.

    Use the solar panels in place of an awning ...now you have a car port which produces electricity.

    Get smart and adjust your power requirements :

    Simple things like running the pool pump during peak sun period...instead of at night.

    make your fridge freezer smart and turn the temp cooler during peak sunny period and even switch it off at night... if you dont open the door during the night it should stay cool.

    there are so many ways to make use of the energy rather than wasting it on a grid tie system which has no benefit/ROI.

    It we werent such tight a$$es ...we would get smart and share our power ...ie get one person to install units go off grid which would result in no tarrif... and share it with the houses on either side ...then they offer electricity at night... everyone wins... but unfortunately we are such a tight a$$ bunch... too worried someone might get more than someone else.


    I dont agree... solar power could ease the grid in a short period of time... it is just not in their best interest (financially) for us to ease the load on the grid.

    It seems you only need to register your system with the municipality if you are connecting it to the mains power.

    Another easy way to make your fridge and freezer more efficient is to fill your fridge as much as possible with bottles of water.

    A full fridge uses less power than an empty one. ( less volume of air needing to be cooled )

    The cold water bottles also help to keep the inside cool during extended periods of power outages.

    You need to look at the tariff card -

    I see they're still messing around with the rate. The last time I looked, the fee structure was a little different.
    But even with this one, a 10kVA system is going to come with a R710.90 + VAT = R817.54 overhead.
    The trouble with opportunity is it normally comes dressed up as work.

    I thought i would phone Durban electricity department and find out more about the requirements for solar power... tarrifs etc.

    Let me just say this... it would be easier to install the panels ...then wait till they come around to enquire about the panels installed.
