Discover how a Cape Town citizen, Erastus Coetzee, conserved over R23,600 in simply 5 months with a self-installed planetary system costing R85,000. Coetzee’s ingenious technique consists of buying marked down 5kW grid-tied inverters in 2019, integrating them with different photovoltaic panels amounting to 16kW, and getting a present of a 3,640 Wh lithium-ion battery. His affordable system, set up in compliance with the law, has actually enabled him to not just recover the preliminary financial investment rapidly however likewise make R10,285 for excess electrical power fed back into the grid. The City of Cape Town’s feed-in tariffs have actually shown helpful for over 869 home users and Mayor Geordin Hill-Lewis sees it as a win-win, including kilowatts to the grid at a lower expense and putting refund in the pockets of Capetonians.

A Cape Town homeowner has actually conserved over R23,600 in about 5 months with a self-installed planetary system that cost him around R85,000.
MyBroadband reader Erastus Coetzee just recently called us and supplied comprehensive electrical power usage figures and City of Cape Town expense quantities.
He asserted that it was possible to get a far more inexpensive solar and backup power system than typically marketed and make countless rand from it to recover the preliminary financial investment expense rapidly, a minimum of in Cape Town.
While feed-in systems are likewise supported for Eskom Direct clients and in other towns, the City of Cape Town is the only authority that will pay citizens and organizations back if their fed-in electrical energy passes usage, whereas other authorities just offer users electrical power credits.
Coetzee stated the overall capital expense of his planetary system at his home in Melkbos was R73,300, while the bidirectional meter and appropriate local approvals took the overall cost to R85,000.
From the start of October 2023 to the end of February 2024, he has actually been paid R10,285 for the excess electrical power fed back into the grid.
This quantity does not consist of the approximately R2,500– R3,000 he conserves in electrical power expenses on a monthly basis, which have actually amounted to over R13,000.
Coetzee joked that Eskom or the city was successfully purchasing brand-new panels and inverters for him to stop consuming their electrical energy.
At the existing rate, he may recover the system’s overall expense in less than 2 years.
This stimulated MyBroadband’s interest, as the time in which electrical power cost savings offset the expense of a solar energy system is normally well over 6 or 7 years.
Coetzee consequently discussed how he handled to put together such an affordable system, which was through a mix of smarts and good luck.
“Nobody wished to purchase the 5kW grid-tied inverters since of the nonsense individuals are talking,” he stated, describing some Cape Town locals’ fear that the city wished to have more control over their intake practices.
“I purchased them in 2019 from a business whose owner died, and due to the fact that nobody had an interest in them, I got them for a much better rate of R5,000 each.”
In addition to these inverters, he paid R8,900 for a brand-new Solis 3.6 kW inverter and R6,400 for a smaller sized undefined 2.3 kW inverter.
The secret to his considerable cost savings is a huge 32 photovoltaic panels with differing capabilities that can produce over 16kW of peak power integrated.
Coetzee likewise has a little inverter and 3,640 Wh lithium-ion battery, which he got as presents.
He does not concern these to be part of the system as they are utilized independently for powering a PC, TVs, and lights throughout load-shedding.
The table listed below programs the elements in Coetzee’s power backup system and just how much he spent for them.
| Erastus Coetzee’s home solar energy system | ||
| Part | Variety of systems and capability | Rate |
| Photovoltaic panel | 5 x 540W | R10,500 |
| 10 x 420W | R13,500 | |
| 15 x 330W | R24,000 | |
| Inverters | 2 x 5kW grid-tied inverters | R10,000 |
| 1 x 3.6 kW grid-tied inverter | R8,900 | |
| 1 x 2.3 kW inverter | R6,400 | |
| Batteries | 1 x 3,640 Wh LiFePO4 | Talented however not utilized for feed-in |
| Overall capital expense | R73,300 | |
Coetzee did the setup himself and stated he did not purchase “elegant things” as he thought it would have been a waste of cash.
Although the system is fundamental, he stated it complied with the law.
Coetzee is among 869 home users gaining from the City of Cape Town’s feed-in tariffs and reward plan.
In between 1 July 2022 and 1 February 2024, the city paidR25.8 million to these usersand an additional 592 business and commercial clients feeding power back into the city’s grid.
Mayor Geordin Hill-Lewis considers this as cash well invested.
“Not just are we including important kilowatts to our grid at a more affordable expense than Eskom’s supply, we are likewise putting cash back in the pockets of Capetonians,” he stated.
“That is how you democratise energy and really put power in the hands of individuals.”
