SOUTH AFRICA – While the race to move away from an unstable national power grid has sparked a massive rooftop solar boom across South Africa, Paul Stevens, CEO of Just Property, warns homeowners about the danger of getting into a “solar debt trap”.
Beyond the initial capital outlay, he says, the surges in non-compliant installations, evolving municipal penalties, and strict new insurance requirements, are creating unexpected financial burdens that unless planned for, could outweigh the savings on monthly electricity bills.
As local authorities and Eskom prepare to enforce hefty fines, with unregistered systems facing penalties of R6 000 to R30 000 by the newly extended September 2026 deadline, Stevens urges owners to look past the "romanticism" of energy independence and address the rigorous compliance that’s now required to protect their most valuable asset’s resale value.
“We’re seeing a worrying trend in which homeowners view solar as a ‘set-and-forget’ solution to load shedding,” he explains. “In reality, though, an uncertified or unregistered system is no longer an asset; it’s a legal and financial liability that can derail a property sale or leave a family unprotected in the event of a disaster.”
Stevens outlines six critical realities that every South African solar owner should navigate to avoid the debt trap:
1. The danger of the voided claim
Many homeowners assume that once panels are on the roof, they’re covered by standard building insurance. However, insurers are increasingly demanding proof of professional installation before settling claims related to fire, weather damage, or theft.
“The days of ‘DIY’ solar are effectively over from an insurance perspective,” he emphasises. “If you can’t produce a valid Certificate of Compliance (CoC) or an ‘as-built’ report like the PV GreenCard, your insurer may have grounds to void your entire building policy. We’ve seen cases where minor electrical fires, even when unrelated to the solar system, become nightmares because the homes’ overall electrical grids were deemed non-compliant due to unregistered inverters.”
2. The sectional title trap
A major complexity exists for those living in complexes or estates, he continues. “Many owners don’t realise that they can’t just place panels on “their" roof which is actually legally common property.”
Living in a complex doesn't mean you're locked out of solar, but it does mean you're locked into a legal process governed by the Sectional Titles Schemes Management Act (STSMA), he explains. "Owners typically need a Special Resolution (75% approval) or must have the roof space designated as an Exclusive Use Area before they can legally install. Bodies corporate can force owners to remove unapproved panels at their own cost of R100,000 or more."
3. The September 2026 amnesty
Eskom and a number of municipalities around the country have issued firm deadlines for solar registration, which Stevens calls a ticking clock.
“The current waiver on registration fees offers significant savings for those who act before the 30 September 2026 deadline. After that, the 'solar fine' will be the least of their worries compared to backdated fees and disconnection risks. Taking advantage of the amnesty is the smartest move a homeowner can make right now."
The Penalty: While Eskom previously made a "U-turn" on immediate fines, municipal enforcement can now include administrative fees around R6 000 plus capacity-based penalties for unregistered systems.
The Benefit: The waiver covers the Smart Meter installation and connection fees which otherwise cost households anywhere from R9 000 upwards.
4. The SANS 10142 technical standard
Something else to watch out for is the fly-by-night" installer who doesn’t use the DC circuit protection, UV-resistant cabling and other components on city-approved inverter lists, or that don’t meet the SANS 10142-1 wiring standards.
For Stevens, a cheap inverter is a triple threat: it’s a fire risk, it’s uninsurable, and it’s legally unregistrable. “If your system doesn't meet the specifications, it's essentially money down the drain because you’ll have to replace it to achieve legal compliance."
5. The change to "feed-in" municipal fees
New "fixed charges" and "availability fees" mean that even if a home uses zero electricity from the grid, the owner may still end up with a hefty monthly bill, Stevens continues.
Municipalities are transitioning to a two-part tariff system comprising:
- Fixed Charges: Even with zero grid usage, homeowners often face "network demand" or "availability" charges.
- Feed-in Credits: To offset these, systems must be registered as Small-Scale Embedded Generation (SSEG) to legally sell excess power back to the grid.
“The financial model for solar has flipped. It’s no longer just about how much you save on units, but how much you're being charged just to stay connected. If your system isn't optimised to minimise these fixed daily charges, your 'investment' could take 15 years to pay off instead of seven.”
6. The valuation nuance
While solar can add 3% to 4% to a property’s value, Stevens says this premium only kicks in if the system is fully registered as a Small-Scale Embedded Generation (SSEG) installation.
“In today’s property market, savvy purchasers are asking for the SSEG registration papers before they even sign an Offer to Purchase. Compliance is now the only way to ensure that your ‘green’ investment actually pays off at the point of sale.”
Urging homeowners to take advantage of current grace periods for registration and to consult with a qualified property professional to assess how their energy upgrades impact their specific market value, Stevens says these upgrades can prevent steep penalties and a significant loss in property resale value.
Pro Tip: “If you’re planning to sell your home, keep all these documents in a single "Green File." Providing this to a prospective buyer upfront can justify a premium on your asking price and prevent delays during the transfer process!”
