Summer month we are generating more than 4MW per month. 15KW Batt so import = 0.
My view now is does not matter who we are paying Gov or China is the same. The diffs is no load shedding, no increase and most important no theft for those who like stealing ...
Savings for us are huge more than R8K per Month

1 x 10KW dual 3KW 7KW grid tied
1 x 20KW 3 phase grid tied
1 x 7 KW 1 phase grid tied
1 x 3k3KW 1 phase grid tied
1 x 10KW grid tied new inverter

52 PV panels 😇
New stuff is now fully sponsored. 😇

I surely can't be the only one here that has broken the 1 Megawatt-Hour for the month 😜

Baie braaf!!!

Hi there.
I would like to create a database of knowledge that people of the public can follow and hopefully find answers to the questions regarding Tshwane.
Sincerely
Jason

There is no benefit in it as the cost at this moment is fixed @ R0.87 + R0.25.  If the talks actually becomes implemented and there is time of use then one can look at that because one should then get more @ peak hour than normal hours.

For now the batteries at night is a saving as my usage for my electricity is when its dark and @ about 11Kw average per day I would rather expand my panels and inverters.
It better cost that way as batteries costs are high compared to panels and inverters.  But when time of use is applied then I think it will be worth it.

Oh dear me.
 
The post was not about my system but about the impact of grid tied and how the COCT put things together so we all can benefit.  But lets talk about BMS.

The BMS I use does the following:
 
Active balancer.  This means that each 12V sub system has its own controller board with a 5 or 10 amp current supply.  When a cell has a serious issue it will disconnect the batteries and attend to the cell thus the cell will be charged using 5amps and then 16 steps down to .3amps till at the same voltage.  The boards communicate with each other meaning that 4 cells get balanced and 4 cells gets attended too.  When done the batt is switched back. During normal operations the cell that has a lower voltage will get charged and topped up to the same voltage of the other cells without switching of the system. It monitor the temp between 2 cells and if to high or low it will cut off the battery. It monitors the charging and discharging current plus rates of each cell It monitors the ambient C and if outside the manufacturers spec it will protect the battery. Batt gets disconnect on HighV and Low V Its all about the life of the battery.  One step more the battery is assembled so that it is under pressure 24/7. This photo was taken during assembly not the final product.
Not sure if you are aware of such system
Thus at 80% of the operational specs this battery should last more than 20 years.
It has a guarantee of 10 years provided data is supplied.
Its not about my system and the looks of it.  Its all about the impact of a proper grid tie system  the savings and the way the City Of Cape Town provides the means to get our municipal account at paid by the sun!!!
 
Not a look at me I am fancy but a look at the savings through grid tie

Its not about the accuracy of the system  its about the savings. 

I have 44 panels on my roof.  Yes on my roof not on a small holding on the roof of my house.  the capability is more that 130KW per day..

This is not about my systems its about the savings the system generates with grid tie

The mayor in Cape Town actually announced that they will pay back cash.  You can trust them on this.
Thus far I truly think the COCT is doing their best so we all can benefit from it.  There been some "changes in their reasoning" if I may and that is beneficial for all of us. They had a gr8 change of heart if you wish and it is working extremely well. I think like all new stuff they had some issues to sort but currently I can only complement them on their calculations and they way they attend to problems. They are doing absolutely great.
I stand to correction but I believe all future inverters mus be a proper hybrid system and not as commonly known in SA.  The COCT I believe is in the process or its already the case that inverters must be grid tied and supply the "house" from solar.
It will be very wise for the COCT to force all solar installations by law to be grid tied and stand alone and not the once that's hybrid and not grid tied.
I do not have a smart setup so if you will forgive me.  I do not have expensive stuff.  It is the minimal requirements to comply to the law.  This is a photo of a 12V  3.6KW Lipo battery with 10 000 cycles.

The total cost is about R6900 and it works extremely well.
 
So if you would spare me the embarrassment.

This is what the daily feedback to the COCT looks like:
The 550W is from Lee Roy Marlin in Oct they shipped it from Jhb
The 420W is from olirosssolar  and sorry the cost was actually R1350 per panel.   https://olirosssolar.co.za/
What a super panel this is.
 

The only objective is to show people solar pays for itself and you add more panels  then your account drops drastically:
My account was way more than R7000 per month.  I did not show all the data as the savings is actually way more

This is a summary of my COCT account for Jan:
  R-1,711.37   R-491.77 Export R-2,203.14 Import R 918.36 Connection Fee R 219.21 Data R 4.92 Tax R 2,092.71 Rubish R 158.30   R 1,190.37

The Time Tariff Rval column is what the council pays "Eskom"   Ttf N Val column is what the council gains from selling solar and not coal.

'n Goeie begryper het 'n halwe woord nodig.  Ek kan nier help as mense nie somme kan maak nie en aanvaar dat almal tegnies gestremd is nie

Basies is ek te lui om detail te bespreek.

Wat belangrik is is 'n Goeie begryper het 'n halwe woord nodig.

As mense nie die berekeninge kan verstaan nie is ek nie daar om dit te leer nie.
Ek argumenteer nie ek wys net uit hoe beperk mense se denke is
Let me add one sentence.  Show me where any person could prove the calculations wrong, the installation cost or where any entity had legal issue.

Surely if no person can proof the calculations wrong and the fact that you can see the impact on my account then you must be very dumb to argue against facts.
My calculations are good, my savings are terrific, my expansion on solar is what every one tell me can't be done yet I show it on my account and then you say I am arguing.
Meditate on it and then you consider who needs to be convinced. 
I assure you not me.
I smile all the way and the people I have guided what to do so do they and frankly as for the rest you are most welcome to support Eskom and the corrupt. 

3 phase 100A per phase.  I thought for those that understand the maths it would have been commonsense.

So you actually support mismanagement, theft and corruption and is 100% happy to pay for a communistic system where by those in power gets it all and the rest of the dummies must enrich the few at the top.

If they can only lie, steel and waste money for what reason must I support such a corrupt system?

They been lying and fooled you and appointed technical firms not based on knowledge but rather creaming the money for a few.  Did you perhaps forget about Zuma and the Gupta's?

There is corruption on every level and what you are saying is lets support it.

The high costs etc is not about technology its all about supporting those that can't think and therefore the manufacturing and design gets forced out of SA so that the dumb can lead the way and actually steel from the poor.

Have a look what the corrupt fake NEWS.  SABC, CNN, BBC ... combined with Google, Meta(FB) they appointed Biden and the whole world is suffering because of your "type of theory".

If technology is affordable why must we allow corrupts to steal from hardworking people?

Technology costs is not expensive the overheads of feeding the systems is  If facts shows that the amount of solar systems installed in SA is greater in KW than a power station like Koeberg which is 1900 MW/Hr, then for what reason must we pay a useless politicians to steel from us and enrich the comrade?

The problem with ESKOM and expenses is not the running and expansion of it but rather those that see it as a personal profit scheme to enrich themself without having the mental ability to create and grow.

Therefore steeling from the dumb and foolish is whats happening here and you are in support of it.
Take note I am not a supporter of any political party so its not about a party it is because we have people voting for dumb politicians why we are experiencing the high costs and the added costs.
 
There was a financial article that calculated the amount of installed solar in SA.  Consider this statement.

Should people be penalized for solar which is the impact of your view, you will have an immediate increase in black outs as the impact will be the same as one of the major power station outage in SA. 
People who installed solar directly impacted black outs. Therefore there are less blackouts and you suggest ESKOM must penalize them because they now have less to steel.

How can this make any sense?

Nersa should rather implement structures that deals with corruption and sort the high costs but then they are part of the same network.
Also what you don't understand if I understand the new tariffs correctly Eskom wants a +/- R1000 just for the connection.
There are places currently that is paying more than R2000 per month for "electricity availability". Imagine before you have any electricity you must pay R2K.
 
Nope when Eskom had people with knowledge working for them they where considered as one of the best utilities in the world and because people realized the cost of electricity and fuel has a direct impact on inflation it was kept as low as possible.

But then you have people that vote for some person called Bidon and the whole worlds suffer.
Nersa should drive costs down not up.  They should look intelligently at the complete model and not simply feed a bottomless pit that has a lot of useless people creaming it.

But then the question is how many at NERSA understand the impact on the poor and the the cost it will have.

No inflation that is the worst tax implemented by politicians should be driven DOWN not up.
For what reason must I pay R1000 per month that the installation costs was already paid for?
What reason justifies this?

I am sure that if the complete cost structure gets manage electricity can and will go down.

Think a little differently to the problem.

I can import a set of gears manufactured in India at +/- 30% of the local manufacturing costs. 
So its better for me to import that to sit with high fuel, electricity and mismanagement cost.
The high costs are driving businesses out OF SA that's the impact.
Think about it.

Elon Musk a South African moved a complete business from California to Texas because of the increase of costs
Apple moved
Oracle Moved and so I can continue.
All based on COST!!!!  and you happily want to allow NERSA to enrich the few at the top.
As for cost the DA is bragging about how they run the Western Cape.  But they are actually worse.

Their tax and cost structures combined with additional laws creates a different animal.

If I manufacture a PC board in Cape Town one bare board in Cpt costs more than the manufacturing, assembly and components for 5 outside SA.
In Cape Town I think the DA said there is a loss of about 700 businesses in the past few years.

People should actually email NERSA with a notice of objection rather than support for these increases.
 

It is inevitable that end-user tariffs will change to reflect realities.    You’re naive if you expect that you can connect solar, over-generate in the day and draw at night and only pay the for the net kWh consumed in a month.    The grid is not your loss-less and free battery and I won’t subsidize your model.   There are idiots with solar and storage that after evening loadshedding run their loads from grid AND recharge their batteries at 1C, in effect presenting double the kVA load on the rest of the country.   Stuff that!
By FAR the bulk of power and energy is delivered under Time of Use tariffs whether that be to metro or council or large Eskom direct customers.    That involves a NMD fee per kVA, a monthly peak demand fee per kVA, peak/standard/offpeak kWh fees and half a dozen other minor charges.   A few small towns are not on Megaflex.
I’ve done large solar since 2013 and my town was a bit silly at the beginning, giving us 1:1 credits.   I say silly because that ignores that they have the cost of reticulation and maintenance.    That party ended and they went stupid the other direction by slashing kWh (to 115c/kWh) so that solar is compared to that not 275c/kWh and because they know there will be a half hour somewhere in the month that the sun don’t shine, they smacked R415/kVA peak demand.   My response was adding more solar and more storage and grid shaving because I’d be stupid not to.   So now have 425kW solar and 600kWh battery on one of my transformers, will do the others this year.
A fair system imposes a fixed fee based on the size of connection you want available (they reserve and pay for that NMD with Eskom), a variable fee based on that month actual peak kVA (they also pay Eskom for that) and then a Time of Use tariff for kWh.    The fastest way we get people to swap power demand out of peak periods (when the country is paying for R8/kWh peaking diesel and implementing loadshedding) is that peak period energy costs R5/kWh and off-peak costs R1/kWh.   Maybe in a year or two my council pays me to inject 200kVA in peak periods.   I can program that and then recharge between 11PM and 4AM.    If they deducted 100kVA from my demand fees for the 200kVA that I wheel to them plus they pay me half their Megaflex peak cost per kWh, they score and I score.
Smarter tariffs need not be bad for consumers, it can also open up benefits.

I guess then with R1K per month for nothing it is better to support China with batteries and disconnect completely.
R1K per month one can then say its a maintenance fee on batteries rather than a connection fee.
The reality is the COCT income from buying excess solar in my case is in the table below.  For the council they have lost 0.  In this case its better to be connected to COCT than Eskom.  This summer I will have even more feedback so I recon my excess will be +/- 4MW per month Sept -
Whats interesting is in the case of council they do not loose any income.  In the case of COCT I think they are very fair.  The table below is the current monthly surplus/excess in KWHr and then the money COCT receives by selling "our solar energy".
1256.083 R-1,066.97 1192.301 R-1,051.24 1833.817 R-1,824.59 1967.088 R-1,998.83 1735.952 R-1,719.64 1724.778 R-1,645.90 1138.854 R-926.68 962.096 R-637.51 685.0925 R-128.63 12496.0615 R-10,999.99 Considering that we have our own RO in our case the COCT out of pocket cost dropped from +/- R7K per month to a surplus.
Our total Kwhr solar inverters is 30KWhr the table above is for 15Kwhr with the increase the R11k should become R22K....
Congrats to COCT I think they have the best model in the country
 

 
 

I don't think you can say nobody is forced to use Eskom. People are where there is no other supplier due to the monopoly.  What they are working towards is to get R1K for availability and no effort.  I do not use COCT water but I must pay an availability fee every month. R250 is acceptable.
The monthly fee for electricity is R219.21 and they do regular upgrades and maintenance.  We very seldom have power outages due to failures so this model is totally acceptable.
This can not be said of ESKOM as they abuse, waste, no maintenance, mismanage  and theft is an acceptable practise.  The R1K is totally to high.
Then in the case of a block of flats where the flats are liable for the distribution with in the flats must they get R1000 x 150 flats or R1K.
If you install a solar geyser (heating not panels) gas stove and people are working with no pool then the usage is very low in any case.

R1K is a subsidizing fee not an availability fee.

So you actually support mismanagement, theft and corruption and is 100% happy to pay for a communistic system where by those in power gets it all and the rest of the dummies must enrich the few at the top.

If they can only lie, steel and waste money for what reason must I support such a corrupt system?

@NoJ, I've been paying the municipal MCB charge in Pietermaritzburg for the last 16 years already. This charge is the basic connection fee dependent on the size of the municipal MCB, (mine is 50A). Before even 1 kW/h is consumed I pay R1068.00 for this connection. 😡 So when Eskom implements a similar structure, everyone will be paying for the corrupt "officials" and all the millions of freeloaders. 
I have had enough of this corruption and freeloaders, and am planing to move to a farm and totally off-grid lifestyle, so as to no longer pay this sickening socialist "tax".
We have people living up the road on "chiefs land" who have "official" illegal power and water connections, with NO meters on water or power. Their multiple spot lights are ALL on at night. At one of the mayors meetings, I brought this and other queries up, and was told, "it's payback time, and to basically pay up and shut-up." 😡
Totally sick and tired of these double standards, so aim to no longer pay this socialist "tax", and disconnect from the system.
Question. If years ago the power and water was so affordable so as not to be a burden, what has changed?
Answer. Mismanagement, incompetence, arrogance, theft, etc....
The volume of supply and demand is NOT the issue. Even illegal connections are due to the the above Answer.
So as to the question of new rates and tariffs, my condolences to all who aim to stay on-grid. 😢
