    7 Solar Power Myths South African Homeowners Still Believe

    Solar is widely misunderstood. We debunk the common myths — about cost, load-shedding, cloudy days, maintenance and feed-in — so you can decide with facts, not hearsay.

    Solar is everywhere now — and so is bad information about it. Before you spend (or decide not to), here are the myths that still trip up South African homeowners.

    Myth 1: "Solar keeps me powered in load-shedding"

    Only with a battery. A grid-tied-only system shuts down during an outage for safety — you need a hybrid inverter and battery to keep running. This is the single most common misunderstanding.

    Myth 2: "Panels don't work on cloudy days"

    They do — at reduced output. Panels generate from daylight, not only direct sun. Over a year, Johannesburg's sunshine makes solar very productive.

    Myth 3: "It's too expensive to be worth it"

    With Eskom tariffs rising above inflation, a well-sized system typically pays back in 4–6 years and saves for 20+. Start smaller and expand, and prioritise self-use over feed-in.

    Myth 4: "Solar needs constant maintenance"

    No — mainly periodic cleaning and an annual check. No moving parts in the panels.

    Myths 5–7, briefly

    "You can go fully off-grid cheaply" — possible but costly; hybrid is usually better value. "Any installer will do" — compliance and design matter hugely. "Batteries don't last" — modern lithium lasts 8–12 years.

    Decide with facts

    Frequently Asked Questions

    Only if you have a hybrid system with a battery or a battery backup — a grid-tied-only system shuts down during load-shedding for safety. This is the single most common solar misunderstanding: panels alone don't keep you powered in an outage; you need storage or a hybrid inverter.
