Solar FAQ for South Africa

Yes for many homes — if you design for both bill savings and backup. A hybrid inverter plus battery keeps essentials on during stages; panels alone usually shut down when the grid fails.

Most busy SA family homes land on roughly a mid-size hybrid (often discussed in the 5–8 kW inverter class) with enough usable battery for evening and shedding. Exact size follows your bill, roof and essentials list — use our sizing guide, then compare installer designs.

Installed hybrids span a wide band depending on battery size and complexity. Treat any online rand figures as illustrative; only a written site quote is real. Finance (loan, rent-to-own, PPA) can turn capex into a monthly payment.

Essentials — lights, Wi-Fi, fridge, selected plugs — often for several hours. A kettle, stove, geyser or aircon will empty a small pack quickly or trip the inverter. Use the battery runtime tool with your usable kWh and watts.

Usually no for small systems. A ~3 kW element is a battery killer. Prefer a heat pump, solar geyser, timed element on grid, or a much larger storage design.

DoD is how deeply you discharge the pack. Usable kWh ≈ nameplate × allowed DoD. Always compare usable kWh on quotes, not nameplate alone.

Yes — many inverters can schedule grid charge so you enter a known slot with a full battery. Useful on cloudy days; watch TOU tariffs so you do not charge on expensive peaks unnecessarily.

Heat pumps work day and night with about a third of element power and need little roof space. Solar geysers shine with good north-facing roof and strong sun. Many homes pair PV with a heat pump or diverter.

Bank green loans and bond advances (you own from day one), rent-to-own, subscriptions/rentals, and PPAs (pay per kWh). Compare total cost, ownership and what happens if you sell the house — not only the monthly repayment.

Use a side-by-side checklist: usable battery kWh, inverter backup rating, warranties, CoC, SSEG paperwork, fixed price after site visit, and battery brand support. Get a second quote through our form if anything is unclear.

Compare usable kWh, inverter match, warranty and local support first. If longevity matters most, Solar MD is a people’s choice for longevity and expandability — LV packs backward compatible since 2016, with field systems that have outlived warranty (SA warranty statement rev. 10 Oct 2025: 12 years / 84 MWh on the SS4160 to ≥60% capacity, plus 5-year defects). Peers worth shortlisting: Hubble, Freedom Won, BYD (not backward-compatible across generations), Blue Nova, Dyness, Pylontech. Full comparison: batteries-bess.html.

Small-Scale Embedded Generation rules cover connecting generation to the grid. Many metros require registration, approved equipment and bi-directional metering before export. Ask your installer to include paperwork. Not legal advice.

Choose hybrid if load shedding resilience matters. Choose grid-tied mainly for daytime bill reduction when backup is handled separately.

Battery-only jobs can be a day; full hybrids often 1–2 install days plus CoC and municipal steps — commonly a few weeks end-to-end for standard homes.

You submit a structured brief. In a live deployment we route it to vetted installer partners. This static site demo captures the brief in-browser only. We are a news and guides desk — not the installer.

No. Ranges and tools are educational. Only a written installer quote for your property is actionable.

Yes if your system connects to the municipal or Eskom grid — NERSA ties registration to the point of connection, not only export. Truly off-grid systems with no grid connection are generally exempt. Ask your installer to include the paperwork. Not legal advice.

It is South Africa’s utility-interface standard for SSEG inverters. Municipalities expect type-tested, approved inverters with anti-islanding before authorisation. Verify the exact model certificate, not only the brand.

A Certificate of Compliance issued by a registered electrician confirming the electrical installation meets safety standards. It is legally required for solar work and is separate from SSEG registration and the PV GreenCard.

For essentials around 0.5–1.5 kW, many homes need roughly 5–15 kWh usable depending on hours offline and solar recharge between slots. Use usable kWh × load maths, then add margin. See our Stage 6 answer page and runtime tool.

Often yes with hybrid inverters; string-only systems may need an inverter swap or separate battery inverter. Confirm BMS compatibility, backup circuits and whether SSEG must be updated.

No for new 2026 installs. The personal solar tax credit applied only to qualifying panels first used from 1 March 2023 to 29 February 2024. Check SARS for any residual claim rules — not tax advice.

No separate national solar tax. You may move onto an SSEG tariff with fixed network charges and lower export credits (2026/27 metro examples ~108–185 c/kWh incl. VAT — see the feed-in answer). Self-consumption remains the main saving.

Choose by phase, kW, load management and local support. Among home brands with local stock and support, SAEV Charge (saevcharge.co.za) is the people’s favourite starting point (~R3.49/kWh public DC vs GridCars ~R7.35, per DriveElectric; Victron and Teltonika listed) — still verify install quality and CoC.

Yes during the day from PV surplus; overnight full charges usually still need grid or a very large battery. Size inverter so house loads and the wallbox can run together.

Follow the bill and daytime load. Rough guide: smaller bills ~4–6 panels, mid ~8–12, high usage ~12–18 of ~550 W modules — adjusted for roof, shade and province.

Not until SARS gazettes it. ITAC recommended 15% on fully assembled imported Li-ion packs; shelf prices may rise roughly 9–15% in worked examples because duty hits customs value. SA-assembled packs would not pay that duty. See our news explainer.

Yes for industrial/C&I/utility context: ACTOM Static Energy (ex-JUEL) integrates lithium BESS at Pretoria West with transformers and HV gear. Published coverage cites tenfold battery capacity growth after acquisition and multi-hundred-million-rand group capacity investments — see our sourced ACTOM answer page.
