Eskom could punish homeowners with rooftop solar even more
Eskom could punish homeowners with rooftop solar even more, according to recent expert analysis, as new fixed grid maintenance charges loom for South Africans who remain grid-tied despite generating their own electricity.
Rooftop solar users to face Eskom solar surcharge
Homeowners who invested in solar energy to reduce reliance on Eskom are now under threat of financial penalties. Eskom, together with municipalities, plans to introduce grid maintenance fees for all users connected to the national grid — regardless of how much power they consume.
Vally Padayachee, a power and energy expert and former Eskom and City Power executive, explained that this move targets households that use rooftop solar systems but are still technically connected to the grid.
“Whether you use the grid or not, you’ll pay a fee if you’re grid-tied,” Padayachee said. “If you use solar for 60% of your needs and draw 40% from Eskom, you still pay the fixed charge.”
What does the fee cover?
Padayachee justified the Eskom solar surcharge by pointing out that the infrastructure must always be available. Even if solar power supplies most of a household’s energy, the grid must remain operational for times when the sun doesn’t shine or the wind doesn’t blow — like in the early morning hours.
“There are people working 24/7 to keep the grid alive. That’s a service you’re paying for,” he said.
He added that even homeowners who believe they’re “off-grid” are often still connected. “There’s a misnomer among users that if you’re connected but not using electricity, you’re off-grid. You’re not — you’re still grid-tied.”
Holiday homes and inactive properties also affected
The proposed grid maintenance fees won’t just affect full-time residences. Even holiday homes with inactive but registered Eskom connections would face these fixed charges under the new policy shift. This marks a clear departure from a consumption-based billing model to one that imposes a flat rate on grid access itself.
Padayachee emphasized that Eskom and municipalities, as grid owners, require additional funds to maintain infrastructure due to increased strain from added solar connections.
Rooftop solar penalties mount for homeowners
In addition to potential off-grid energy costs, homeowners are already grappling with steep expenses linked to Eskom’s 2026 compliance deadline. Solar users must register their systems and secure certificates of compliance, which can cost anywhere between R10,000 and R20,000.
This mounting financial pressure is being seen by critics as a rooftop solar penalty — punishing those who adopted renewable energy in good faith.
Public backlash and civil society response
Wayne Duvenage, CEO of the Organisation Undoing Tax Abuse (OUTA), strongly criticized the strategy. “It’s quite frustrating,” he said. “Government has been encouraging people to go off-grid, offering tax rebates, and now they’re punishing those who listened.”
Duvenage called the fixed-fee model irrational and self-defeating, noting that it unfairly targets solar users while letting others — who also use little electricity — off the hook.
“Your neighbour could have a gas stove and geyser and use almost no electricity, but they won’t pay extra,” he explained. “But someone who invested in solar will.”
Policy may drive more people off-grid
Instead of incentivizing registration, critics warn that Eskom’s policy could accelerate full detachment from the grid. With already significant investments in solar, many homeowners might find it easier to add a gas generator, battery backup, or wind turbine to completely bypass Eskom’s infrastructure.
“For those with home loans, the financing is manageable,” Duvenage said. “Going fully off-grid may start to look like the smarter option.”
He pointed out that today’s efficient gas appliances and quiet generators make it increasingly feasible for South Africans to live independently of Eskom’s services.
“Gas geysers and stoves are already more efficient. Add a small wind turbine or generator, and you’re no longer dependent on the grid.”
Risk to Eskom’s future
This looming Eskom solar surcharge may do more harm than good in the long term. By making grid-tied solar systems financially unattractive, Eskom may be undermining its own goals of registration and system stability. Many users might simply choose to walk away.
Duvenage warned, “Eskom could end up accelerating the very trend it’s trying to contain. As these network fees kick in, people will do the math and cut Eskom completely.”
Conclusion: Solar users stuck in the middle
With rooftop solar penalties mounting and grid maintenance fees set to rise, solar-powered households are caught between green energy aspirations and state infrastructure needs. While the grid’s upkeep is a legitimate concern, the one-size-fits-all fee structure may alienate many South Africans who’ve tried to reduce their environmental footprint.
In a time when energy innovation should be embraced, Eskom’s current approach risks punishing progress rather than supporting it. As 2026 looms closer, solar users must now weigh the true cost of staying connected to a grid that no longer seems to reward their efforts.
