  1. Oh I am Afrikaans so my English not so good. I have already put the figures on the table in table format. I have a model right down to every 1 minute in measuring and .. My bad language and lack of expressing is sufficient to say you guys won and good luck.
  2. prove it with figures please. Let me try and explain again. if you use 1330 Kwhr per month OR 43Kwh per day. The cost is in Cpt 600 x R 2.09 = R1254 730 x R2.65 = R1934 R3188 Take note mine was higher. If I now push back 730 Kwhr 720Kw equals 24 Kwhr per day. Lets calculate: 730Kwhr per month x 12 months divide by 365Hrs equal 24Kwhr thus for an 8 hour day you need 4Kwhr for push back. First the R 1934 disappear. That means I am already saving R 1934 per month. Simply put just on the penalties. Now do you honestly want to tell me this can be done with batteries if you have to replace them VERY OFTEN and struggle and struggle an new topic is already showing an new installation with problems Just that takes away you meter cost, your levy if you wish. And most important the R1934 is staying in MY POCKET and you want to tell me its not worth it? I bet you drive 5 Ferrari's and live in a R160M house or am I wrong? The fact is the R2K will pay the solar and once paid you do not have to buy new batteries fancy electronic devices that can not be used for an anchor and throw money in a bottomless pit. Come on R2000 a month TAX FREE increase for doing nothing is about 10% of 40% of this countries work force. Your financials does not make any sense and that is the problem a lot of talk and no facts. Thus again if I take my pathetic system of R56 K compare it to alset of my friend that cost R285K I have no battery issues that they already have and I save a lot more. Then let me share another point go and look at the accounts the costing in COCT is now split into two costs. My question to the power was simple if I have free internet and the Landis & Carr meter works on internet why must I pay the high fee. The next account came R85 for comms and R165 for maintenance. Now let me take it one step further. I did the maths send the facts to the City of Cape Town. with the cost of the batteries the money flowing out of the country to China the constant issues as per this site and the cost analyses the City of Cape Town gave a 25c intensive. If I dig somewhere I can show you the emails to several people both political and financial I contacted. It does not make sense to let this amount of money go to China plus the issues that comes with it. For that I am in favor of a 50% import tariff on those batteries as they are not worth it. Therefore we can fight about load shedding, we can fight about who has the smartest and most expensive system that it requires constant attention repairs inputs money ... Lets make effort to communicate with FACTS to the powers and ithey will listen and already credit to the COCT they listen and then did changes. If I kept quite grid tied in COCT would not have received the 25c increase and they would not have split the cost so we can provide free internet. I even offered them to install routers, communications device it will be a once off of +/- R8000 then we all can gain from not paying Vodacom MTN and ... But funny not a single person is prepared to take me on. When you do the calculations the looser is China, Eskom, Zuma, Gyptas, not me and those who see the light.
  3. If you can get 11c back on surplus. It means for +/- 10 hours a day you pay R0.00. If you look at 07H30 and 18H15. I have used .663 Kwhr and pushed back 38.4 This 38.4 for this Kwhr on this device meant the following: It stopped my total Kwhr from increasing It prolonged the step tariff there for I never reach the higher values. This means that all my needs plus was not billed for. The majority of my account was billed at tarrif 2. This means that the way you get nailed when you cross that threshold in my case was the bulk of my account. That has dropped to 0.00 IF I now use Eskom power I never reach the 600 Kwhr mark. What you should know it is for more than one house hold. Its not always what you getting back is what you are also preventing the cost between 600 - 900Kwhr = roughly R900 the cost for 0 - 600 is roughly R 900. This has been totally removed from my account. Therefore a thought If I buy 500l diesel from lets say Caltex and I return 500l is the difference between cost and profit returned by Caltex or is the cost of the 500l returned. I believe that should be tested in a court of law. The proof is in the case of COCT they do not have to pay Eskom, they can sell my Kwhr for 4 times the cost of Eskom. The constitution states that a local authority should not make a profit. I have proof that they made more than R37 000 on a cost of R2431. Who knows but I would love to test that, We all must remember that SSEG is not that old and the more we give input and facts to Nersa and committees the greater chance we stand to be treated fairly. If I am limited in speech its be cause of I would love to test the depth of the water so we all can walk easy in the future. Perhaps next year who knows. But that there is a common incorrect billing attitudes and calculations is to put it mildly. I have added NERSA "current" view on SSEG.

  4. Something trivial, Although I developed m on packet communications and spend a lot of testing in Europe etc. I do not spend R50 per month on my cell phone. I dislike it to much so I never think cellphones They are just to useless to be worth something, Of times, data connection errors small in memory then batteries my favorite subject... I would still like to push it into a deb somewhere. I have an ISP so I have a few servers maybe we can look at that in the future Data is always valuable and can perhaps lead to other stuff...
  5. Let me check on this. I never bothered to check else where and ask about it maybe its time to do so. Wonder how many others will be interested should Jhb offer the sam as Cpt....
  6. The COCT currently pays: R 0.7551 per Kwhr and an incentive of R 0.25 a total of R 1.01 EX VAT. My average usage per day is 9Kwhr when my solar runs 100% normal and in the installed positions This cost me +/- R 18.09 per day or 20Kwhr push back then I have a 0 account. I do not want to give my exact Kwhr on this page but I can assure you I do not measure in Kwhr for my electricity generated... They also increase it with the Eskom rates then a 20% will be R 0.91 + R0.25 = R 1.16. If only they can go to time based billing. Now in Cape Town the calculation are benefiting the council but not worth while to support China.
  7. Nope I have three grid tie inverters. My old inverter that I used with the 48V if you wish batteries is standing some where and rusting. I use 2 x 12V 7.5A batteries a small charger for my lights backup .. When I started grid tied I was not sure so I bought a 1.2Kw Solis. It did not last in my conditions and the salt / damp blew the in puts. Then there where some shortages and I got me a 3k3 solis grid tied. Cost was if I remember correctly R8300 hope I am right. Then my other 2 cost a little more at R5K each. Three inverters something like R18300 can't remember the Solis price. I don;t bother about the stuff anymore but I think I have 8 or 10 second hand 330W panels. It was around 12K for it could not remember. That brings me to R30K keep the change. Like I said others thought its rubbish its still generating the same power as when I got it. When my wind genie works properly I recon I will add another 2 10Kw units..... Because I am designing the electronics the genies will connect to the 10K plus these units and I recon in the good winds I will push 14 - 17Kwhr per turbine. Or in low winds something like 350W. Trust me it is basic installation. I took a dedicated 3 phase cable from my 1 DB to the roof. Have an isolater switch 3 phase. This T in after my main cct breaker. In the meter box on the pavement I have 3 120A breakers. Each inverter has its own cct breaker on mains. No junction boxes no other electronics except my own power meter. Three DC fuses for the solar panels. Mean and lean. Each inverter has its own set of panels with a good 220V cable to the little DB with breakers. It complies to all specs rules and safety and ... In total 9 meters conduit. The cable was expensive as it is a 4 wire 120 amp per phase cable if you wish. And that is it. Not impressive not expensive not fancy not something I will show photos of as it is nowhere in the league of what is installed and showed on this blog and rightfully laughable. Some people that came to look was shocked how little and how basic. A proper cheap and nasty was a comment. The back up. They are either 12V or 24V depending of the LED lights. I started running 12V then realize its a waste. I am getting another 5 batteries next week for some more stuff and they are brand new R75 each. Gell no fumes no issues no ... It can either switch automatically to backup lights or switch on via a switch or CPU Cheap and nasty and extremely effective.
  8. This is a problem. Therefore should we not draft a "petition" and get this "enforced" as the tariffs are enforced? Currently I am debating with the local people on the basis if we have time based meters and which is a requirement why do we not get time based billing. I fixed the cut and paste. This is what the COCT should have paid Eskom for my electricity R 12,839.59. If they are paying Eskom R 0.391 per Kwhr at night and they take 100% markup we should pay R0.80 not R2.00 Note that from Sept 2019 - Aug 2020 nothing registered on my account. Then in Aug 2020 the council did something and the feed back registered. Still incorrect but it was something. After some issues they decided to replace my meter late Oct 2020 and the rest is clearly obvious. Then June July Aug I worked on my house and solar was not working 100% as I had to move all my panels remount them as my house developed a serious water problem with the water rushing in through my concrete top and caused sever damages to my house. 15 MONTHS I had bad figures and since Aug 2020 after calculating what they had to pay and the difference by selling my electricity which they "now get for free" my total electricity cost them R 2431. That is from Aug 2019. Now do the calculations then you will actually see how much they are reaping from us. On top of this they have a moving billing period. This playing with dates cost and extra amount R6758 for this period mainly in early 2020.

  9. It has already been posted. So why again?
  10. And here we go again: Info/Opinion on system not delivering as expected Look at the article ...
  11. I have already done it in another topic So why do it again? If people did not believe that then why should they believe it now? Any person should be able to calculate. If I paid R3500 per month electricity and now pay R0.00 I save R3500 or 12 x R3500 = R42000 per year. If I have to replace my batteries I must safe this and donate it to China again. Very basic stuff. My system cost me R56K my backups a few bob if they die I through it away and get a new battery 12V 7A R75 x 2. Thus R56000 - R42000 = R14 000 left in 12 months. It is actually more but lets keep it at this it is easy maths. In fact my system is so basic, ugly and so stupid I am embarrassed to refer to it. Some of my panels I bought second hand because others thought it was rubbish. Few years back I had 4 rows of 4 x 12V x 200A that I charged with out an MPPT. I sold it as scrap and got a few R000 for it. Then the decision was made no batteries again. Please note if you have to use batteries then this is not part of it. I am too embarrassed to compare my system to those who spend R100-R200-R300K. But then If your electricity is R2000 a month and you save R1800 on a R200K system which is not much BASED ON THE INFO of others writing here it will take 100 months to break even. Then I would like to know who has a R200 000 system with fancy batteries pays no electricity have no issues and in 12 months got 75% back on what they spend had no problems and did not have to lift a finger. Can you guys send me the list please. Let me make it clear to do my job for me I got 75% back in 12 months. If you spend R100 000 then you must have save R75000 in a year R200 000 savings is R 150 000. Please do not forget the list I would love to go and visit and see them. There might be so many that me and my wife can go on a year touring journey to visit the people. By then the reality is after some time your batteries from what people write will have issues and then it will cost a this and a that and another amount of money. This is not me writing this, this is clever people on this blog with expensive batteries and ..... Therefore shoot them not me. Take note I have spend 000 except if I expand to caver more the get more back. Not a singe cent. Imagine I spend R0.00 with a pathetic system. The only problem I have no brag rights as it is basic, cheap, ugly and pathetic and even second hand I never have to ask about battery voltage charging systems maintenance. My system has no issues and now I am doing the wind turbine. From my little database and info gathering I am now challenging the calculation of electricity for grid tied systems. I have asked for time billing and .. Next year I will make a proper submission to the mayor comity to re look at "kick back" and... I wonder how many will have to support China for odds and sodds? The facts if we do not calculate argue and get inputs we all can fall in a grove and the difference between a grove and grave is the depth. The calculation on feeding back and profits is extremely simple and so are those on expensive batteries. The people who write in this blog constantly have issues please TAKE NOTE NOT ME THE PEOPLE PRO BATTERIES. The cost of batteries are a given, the maintenance and up keeping as put out in this article nothing but a disaster and always another expense. I am not going to do the calculations but let me share with you a little what I do. My business equipment must have a 24/7 up time else I am loosing a lot. I tried all batteries for load shedding for our electronic equipment. My 12V 10X and 200amp batteries are 4 - 7 years old. These batteries I paid R1800 for a 120 amp battery. The chargers I have designed and use is extremely low cost try it 50a 12V/24V R195. So if you truly want to take me on get any one on this site to compare batteries with batteries. If you want to go one step further I can show you comments from the design engineers of major suppliers of batteries commenting on my designs. In no other words cost wise, easy replacement wise and maintenance wise there are some batteries that I can not recall when last we have visited them. Every single outage for the past years they operated and still going strong. I do not know what the cell voltages are or have to worry about this or that. Would I swap them for these expensive stuff not in a million years. Sorry to say batteries are not there to safe with. They are there to supply power in an emergency and never a good product to safe with. This may create a far more sinister messages but roughly put read what the people NOT ME say about the expensive stuff. Some one tried to sell a faulty battery for R10K. It fascinates me that people still try to convince people to get batteries after I would argue the most articles is on this blog contains "expensive batteries life cycle and charging and maintaining" it. Why on earth would I dig a deep whole for myself and almost kill myself by jumping in it? Not me chatting about it but others. Go and read it. The interesting point is every one discusses how to get maximum charge, maximum life how expensive these wonder batteries and they are better than sliced bread. Well I do not talk about my system it simply works requires no attention and no costs. As a fact it is the reason why less money is leaving my pocket. But why then does so many struggle with these wonderful products? Help me understand it please. If the suppliers know what they doing and they can't better on my dumb and stupid deep cycle batteries how on earth must I believe that it is a good product when almost every article is about struggles? If they are that wonderful as many claim I am sure Ferrari will pay you millions to get them for F1 racing. What I don't understand not a single person in a single discussion could explain TOTAL cost and savings versus grid tied. Let me return the challenge you beat me and proof me wrong then next year I will arrange for an Ox braai for those who wants to come and enjoy the day with who are there. Free and on me. Any one can challenge me if I am right then you pay for it and pay me double. In short put your money where your mouth is I am prepared to do that. Please not you are more than welcome to insult and challenge me. Something went wrong with cut and paste I will fix it and paste again Coun Col R @ Step T R 386.77 R 397.90 R 430.67 R 430.67 R 505.36 R 505.36 R 576.29 R 576.29 R 591.49 R 591.49 R 621.34 R 621.34 R 559.28 R 559.28 R 463.78 R 479.68 R 342.63 R 371.24 R 377.23 R 396.89 R 435.21 R 448.50 R 525.02 R 562.13 R 314.40 R 443.25 R 198.71 R 396.29 R-174.11 R 268.36 R-380.42 R 237.76 R-595.19 R 214.21 R-911.39 R 179.05 R-1,036.43 R 188.49 R-310.38 R 345.16 R-228.04 R 341.87 R 31.63 R 412.71 R 641.31 R 973.62 R 536.83 R 946.33 R 236.33 R 812.78 R-532.08 R 307.50 R-493.81 R 366.00 R-493.93 R 352.97 R-187.50 R 112.45 R 2,431.00 R 12,839.59
  12. Good grieve, Reading all the issues with batteries I am so glad I dumped mine went on grid smiling all the way and final;y I am getting my monies worth. A lot was attacking me when I indicated that batteries are extremely costly and almost useless COMPARED TO GRID TIED and thanks to all I never knew so many agrees with me. Think about it no extra logic, electronics. My light backups are from a few 12V gel 7.2A @ R70 when they go I dumped them. I do not worry about heat, Celsius cost cycles over voltage under voltage R140 and I have 7 hours backup. After a few years I dumped them and thanks to Eskom increases I do not feel the pain. To all of those underlying my point about batteries not worth it and very expensive and requires a lot of additional junk to try and make it successful I appreciate your support, Thank you. Many thanks to all this article underlines why people should go grid tie and not support the Chinese and buy a lot of expensive problems!!!
  13. An increase of 20% is a very good thing. Then I get 20% extra on my electricity feeding back into the grid. So please stop complaining it a very good idea. Next year they must ask for another 20% then I get even more. I do not have to worry about cells not charging properly get additional equipment for monitoring the cells. This means I immediately get more back and a far better and faster ROI. Yes they must get the 20%. I What a pleasure I am getting 20% increase because other steels. They should actually award Eskom 30% increase. Go for it I am smiling all the way what a pleasure. Dankie Oom Zuma & Co
  14. Are yopu referring to a string or a single panel or to the cables? It takes about 30,000 volts per centimeter, or about 75,000 volts per inch, to jump a clear air gap. Once the gap is ionized, the sustaining voltage is less. That’s in normal air, at normal temperature, humidity and air pressure, with nothing else near the gap. Sharply pointed electrodes can reduce that a bit for short gaps. Nearby ionization sources can also encourage arcing.
  15. It is but drops a little at lower loads,
  16. I could not get it to work unattended and then I put the new dial indicator on the disk and realized the disk wabble. So its back to the lath shop to get it trimmed not to wobble
  17. Here we go the next phase is starting. A basic plan (not that there is much more about it) of the steel design. Once again the less humans and engineering the better of we are. It appears that the only welding will be where the disks meets the shaft unless someone has a better idea. I am extremely limited when it comes to steel work. The mounting "steel" ( due to a lack of how to describe it) is from a section of rectangle tubing cut and bend in a U shape and 800mm x 600mm x 600m for Nr 1. Its always easier to go smaller where extending or enlarging it comes with a BIG delay. One thing I learned "engineering ... builders....makenixes ..." Sorry don't know how to rotate the drawing
  18. Not a silly question. I have "my own" three phase 10Kwatt inverter that will be interfaced to the turbine. So I can do what I want to do. For this reason it is easy to dump the MPPT and do an PV emulation with the same controller. Thus I can save on component cost and interfacing cost. I am not fond of MPPT as it caters for a bad design, Each MPPT has its own complications and all it is as I said in the past to compensate for a bad design. It also has its own losses Hopefully I can run two three phase inverters on it one for the PV and one for the wind generator, THAT IS THE ULTIMATE GOAL. In my case I am working towards a larger unit 4 or 5M one depending on the success of this one. There is a fair amount of EXTRA logic involved as the coils and magnets could create "cogging" very fast. My objective is to make use of small to large size winds. I want three moving parts which is three bearings nothing else. No breaks, no gears no MPPT no ... With my own 3 phase meter that will form part of lets se what we will get. Its gettting close to putting the first one together.
  19. Be extremely careful of any urine or anything to do with waste. If you do not check it and some one has issues its a criminal case. RO is absolutely fantastic. No doubt. I developed and build my own. Can handle sea and fresh water. The problem is the source of water in some cases RO CAN NOT PREVENT certain nasty stuff due to the "size" if you wish. This is a very basic explanation. If you look at the standards required for gray and black water you need at least one tank that you can turn the water with bacterial filters. That means a small air pump media etc etc. Then when it passed that after X hours not 12 but more that water then gets blasted by a UV and then it must be tested verified and certified. Its not like taking "kalk" or lime or sea water. Human contact how small in a closed loop can lead to death ....
  20. Tank size is the problem not the turbines or the pumps
  21. Let me share with you the past 24 Hr graph. Based on facts not gut-feel my view but hard core facts: classical graph of 24 hour usage. For the past 24 hr we used 60 min power from the grid (Yellow line) Timers are back on. It started yesterday morning at 05h30. At 06H30 the sun started warming the glass tubes 07H00 somebody bathed the geyser was pulled down to 39C and a quick heat by the holding tank 25 minutes later the geyser was back at 54C The complete day went by not a single minute power was used. Late last night the using of hot water 20 unit During the night a top up of 15 minutes Thus for 24 hr it is 25 + 25 + 15= 65 minutes of heating or 3.1Kwhr My feedback to the grid yesterday after all my home usage was paid I still had 38Kwhr spare that went to the rest of the account. The only maintenance is the small circulation pump @ +/- R850. Here comes the trick: Free water Free power Free hot water Account paid via solar and some spare What I will do is add another 10 or 15 panels I recon on a "colder" day that will keep the water good. If I had a fancy timer or a heat pump or gas the cost would have been a lot more Grid tied & Vacuum tubes and surplus solar power is unbeatable based on facts not assumptions or gut-feel. Clearly shows all the timers is wasted money so is gas as you always HAVE to pay. Do it right and hot water is totally free No other system with expensive timers, heat pumps and or gas or even combination can give you this. If you run a geyser from batteries that is even more expensive. If you have to use batteries or gas that's something else. I red you have Eskom it will pay you to become grid tie and you then can even get your money back on the expensive batteries and ...
  22. On my solar system I invested +/- R56 000 the geyser was +/- R 12 000. The ROI more than R5000 per month. This figure is lower than actual figures. 14 months the investment is 100% back and I keep on getting money back. You are 100% right

  24. I had one of these just a different make. I find them better than my new one that heats a manifold.
