COCT Generation of set Insentive makes batteries to expensive !!! Well done COCT

You are currently making good return and your system will have a very high IRR, but it seems you are exporting more than what the CoCT SSEG system allows for (ie you are not currently a net consumer). Net consumer is calculated on annual consumption and production so you might still be ok once winter is taken into consideration, but seeing your impressive tracker results, I'm not sure :)

You are missing my point about having the option to add batteries, of course it will be more expensive and thus IRR will be potentially reduced but batteries are all about having power when Eskom can't supply - for most people (not you), eliminating loadshedding, is as important as the ROI. On a small residential system the Hybrid inverter may add R10K up-front, but then you are at least able to add batteries at a later point if the feed-in tariff is reduced (or eliminated) - or loadshedding ramps up even more.

One of the main problems with CoCT SSEG feed-in system is that you are effectively entering into a 1 year contract with the City on your 20-25 year solar investment. The monthly SSEG connection fee, tariff and feed-in tariff are changed annually which means your system IRR is very vulnerable, especially if it is dependent on the feed-in, to achieve savings (eg. City may only offer R0.33/kWh feed-in next year or R0.10/kWh or none at all.....). The R0.25/kWh incentive is for first year only and may not even apply to systems added in future years. If CoCT would offer a feed-in deal fixed for 5 years then we'd be able to do our sums and make much more informed decisions.

With a self-consumption battery system you will fix your R/kWh rate for life of system (currently R1 - R1.50/kWh) so it's a bit easier to work out the IRR as the Eskom kWh tariff historically has only ever gone up. Feed-in tariffs world-wide have mostly been coming down.

Currently, hybrid battery system in Cape Town expected pay-back is 5-8 years, grid-tie SSEG can be as low as 3-4 years (but no grid - no worky).

Nope,

I am not missing your point.  Not at all.

I do have batteries and I do have a backup.  I just don't pay R25 000 for a battery.  If I tell you what I pay I will get more aggression to my response but I can assure you to have all my lights on it cost me  R1300 a seed generator cost is R2300 so during the day I have no load shedding at night I watch TV have lights  and if I really want to I can have a 3Kw back.  This is where the system got to match the need and that I agree 100%  but there is no way I will fork-out R50K for batteries if I can not be affected by load shedding and spend a few $. R50K can build me 4 wind turbines.

Simply put I do it differently same with my solar system and same with my tracking device and the same will be with my wind generator it will be all part and parcel of the system

My ROI back for my system 11 months not even a year. 

With reference to my tracker who cares what who thinks what the fact is showed in my account from the COCT and hopefully when winter comes my inverters will be driven by my wind generators and at night in the summer soon also by my wind generators.  At a cost of +/- R12K for 4 -4 Kwhr generator its a no brainer.

Hopefully soon my database will be complete and an online interface that will be realtime available on the internet then it will be an interesting toy.  You will be able to see the direction of the panel Kwhr by a turbine a set of panels and the usage by my house plus feedback to the grid,

For payment
The minimum pay out is going to be "ruled" by NERSA.  Eskom can simply not manage millions of SSEG. It will be a night mare for them and any organization. Therefore the most basic way of "handling" SSEG's is via COC's and a meter.  It will also minimize bypassing accounting and to many spinoff's. 

Managing SSEG are costly and it make sense to CHANGE THE LICENSE law to conform to this pattern.  Billing systems are already functional in this way so there are no additional expenses.

A simple example the council had some dumb rule to control my on my house and I continued with my panels. Si they criminally charge me and the ruling was simple.  First Constitution, 2 National law 3 Regenal law 4 Council law. 

Thus the suggestion from Eskom overrules the councils views and laws as it will e done on a national level, Thus the contract between me and the council will become useless and the national "law" will set the minimum standards payment included.  What the council done is added an additional insentive for people to go solar.

My opinion this is ANC against DA.  DA wants to "criple" Eskom strong hold and allow other players and generators.  That they have achieved and what Zuma & Co did althoough they tried to steel max from us as for Eskom they did all of us a massive favor. They will not be able to walk back on performance and solar.   The excuse they have about wetr coal and nonsense is simple.  The station they build is not good enough.  Its not a lack of maintenance as they stated because no maintenance person was laid off they all still in service and working.  Brian Dames started the lie and everyone "ry dit hol rug".

The reality is simple we got to thank Zuma for Eskom HE and the ANC then broke the back of unions, EFF, coal mines and ... without thinking what they are doing they did all of us a favor.  They can not get out this whole easily.  The power stations they just installed are substandard. Think about it no idiot in Eskom ever thought about building a solar roof on the coal so protect it fro getting wet.  They won't then they do not have an excuse.

Solar and payment is here to stay.  The only thing NERSA must now do is a simple  rule/law.  Lets pay a network fee but give us the right to sell to the highest bidder. That means no council will dare to lower the amount a SSEG or who ever gets paid.

You are absolutely right. Each house hold has its own needs never argued that.  All I am trying to show people that you can get going for less work to a good system. My friend choose Tesla het spend R

Erastus has a point!

This nonsense of having to be a 'net consumer' doesn't figure with me other than  to to keep the trump cards in the utility's hands. If they are managing to deal with power fed into the grid today then problem solved! 

It's a blunt instrument IMHO! 

Whats IMHO?

Eskom said no license no ... up to 50MW.  Who on earth except mines uses 50MW and then if it is covered by one "grouping"  simple one for all and all for one.

Laws are changing and that because of the Eskom that choose to install bad power stations.
