So you added the 18% and then the 12% to the 89 odd cents NERSA buy back tariff as well as the COCT tariff? 1 hour ago, NoJ said: I recon the payback by 2024 "should be" R1.044 per Kw no subsidy and the low rate of the City should be R3.0264. That is if they apply 18 and then 12%. I mean a 30.2% increase going to be something for many. Not 100% accurate calcs but close enough. Currently the more you can export the more they will buy from you. I generate more 2MW per month and its quite something if you do the calcs. I'll bet. If they waive the nett consumer requirement. I figure I can only export about 60 to 90 kWh per month. You're in a very different league (I think I did make the qualification that if you can export a lot then it may get worthwhile). 1 hour ago, NoJ said: I can buy a small car with insurance from the amount I am saving that I do not have to pay the council. I can tell you your theory in the case of the COCT is for sure wrong. Saying this I have a few more than 12 panels and 3 inverters They never complained and I can assure you every .01C has been taken into account by the council. On this I must credit the COCT regardless of who said what they have been more than fair with whats been put back not only for me but for those we assisted to push back and that is quite a few kw. If I had 2MWh to export each month, I'd be signing up in Jo'burg. But that is a lot of excess to have - unless you designed your system with that sort of export in mind. My usage used to be 600 kWh per month on a bad month, a month where I felt I'd disgraced the entire family. So exporting 2MW was never on my horizon. I don't really want to knock any City, and TBF COCT have taken this a lot further than anybody else has. When COJ announced their plans to mitigate against load shedding, it was all about gas turbines and ripple switches and no mention of buying back excess PV. OK... the big advantage that COCT have is the Steenbras pumped storage scheme. Jo'burg doesn't have any sort of storage that they can charge with PV during the day and then deploy in the evening.

You can not beat this as the choice is very basic: 1 DO you pay Eskom and council 2 Load your roof and use their money to pay for your solar. 3 Years later and you smile In my case my solar complete is paid in full in 3 years. a Total of 15Kw inverter and about 30 panels (what ever) .

Regardless of what . What I would like clarity on is whether CoCT will be doing away with the generation size limitations based on NRS-097-2-3. The example above is a 15kW residential system, which I assume has to be on a 100A 3-phase supply in order to comply with the limits as per the table below. On the understanding that this requirements document is still valid??? I mean I'm sure they will buy any surplus you can spare, and that they don't limit you to being a net consumer, but surely the technical standards and limitations for exporting still apply?? Or not? Anyone have insider knowledge? https://resource.capetown.gov.za/documentcentre/Documents/Procedures, guidelines and regulations/Requirements for Small-Scale Embedded Generation.pdf I'm going out on a limb here guessing that most residential homes in CT are not 3-phase, probably mostly single phase 60A-80A?? So already the popular 8kW hybrids exceed what can be registered for export on most homes. Most will be limited to under 5kW systems, and at that level the economics are not that favourable to cover self-consumption and export. Or what am I missing here?

We have obtained permission to pay suppliers in cash directly. We will buy what ever you can sell to us". If there is a word or two wrong forgive me. The president has already stated no license required for generation below 50MW I believe more accurate is 5MW. The old way before this announcement the City work on +/- 1/3 of your supply. 3 phase 120A/P = 3 x 120 = 360A 360/3 = 120A. Rough calculation 120A x 240V = 28.8KW OR !!!!!!!!!!! 28.8 x 24 x 365 = 252 288 / 12 = 21 024 or 21 024 x R1.04 = R 21 864.96 x 1.15 = R 25 144.70. Thus with their old stuff it was possible to PUT BACK R 25 144.70 per month (get). This is rough calculations That now has been lifted and you can push back what ever you want. You can also ask for an upgrade to 120A 3 phase connection. That is What was announced

But doesn't that bring you back to square one once the additional battery is charged i.e. idle PV? ........ If you were using all of your PV with one battery you never had any to export anyway.

If you were using all of your PV with one battery you never had any to export anyway. Yes sure, some days you might still be idle. I am idle but another 3,6 battery will solve that for me if I really want to make ise of my spare solar - definitely better payback than the proposed export t&c and a 10k meter (even a 5k meter) But if you have so much spare capacity that an additional typical 3-5 kW battery can’t absorb that (takinf into account winter and loadshedding) how many panels did you go with
