Grid & metering
Eskom Direct vs municipal supply — what changes for home solar in South Africa?
Whether your erf is on Eskom Direct or a municipal distributor changes the SSEG forms, meter process, tariff shape and who answers the phone — not whether hybrid solar “works.” Homeflex and municipal net-billing / feed-in rules are different products; lock your supply authority before you model export cents or prepaid migration.
Updated 27 October 2026 · Illustrative ranges — not a formal quote, credit decision or legal advice.
Answer first: Read the top of your bill for the supply authority. Eskom Direct customers typically follow Eskom’s SSEG / Homeflex path; municipal customers (City Power, Cape Town, Tshwane, Ekurhuleni, eThekwini and others) follow that metro’s embedded-generation rules. Mixing the two in a spreadsheet is how export income fantasies appear — SSEG · Homeflex · metro tariffs · 2026/27 tariffs.
What usually differs
| Topic | Eskom Direct (typical) | Municipal (typical) |
|---|---|---|
| Application desk | Eskom SSEG / Homeflex process | Metro SSEG / EG desk |
| Export / gen-offset | Homeflex gen-offset style rules | Net-billing / feed-in / zero-export by metro |
| Meter change | Eskom metering path | Metro or appointed partner |
| Prepaid | Constraints vary — confirm in writing | Many metros force conventional for exporters |
| Fixed / network charges | Eskom schedule lines | Metro fixed / capacity / SSEG fees |

Hybrid hardware does not care — compliance does
NRS-listed hybrids, CoC and anti-islanding still apply on both paths. What changes is paperwork, export-limit settings you are allowed to raise, and the bill shape after commissioning — NRS list · islanding · export limits · CoC.
How to brief installers
- State “Eskom Direct” or the metro name on page one of the brief.
- Attach a clear bill photo with tariff code visible — read an Eskom bill.
- Ask which desk files SSEG and who books the meter.
- Model savings with that desk’s fixed charges, not a national average — fixed charges · monthly savings.
Estate and farm edge cases
Some estates resell electricity or sit behind complex HV/MV arrangements. Farms may be Eskom Direct with long LV runs. Ask who the licensed distributor is before assuming a metro PDF applies — estate / HOA · farm solar · NMD.
Red flags
- Quotes that promise Cape Town net-billing cents on an Eskom Direct erf (or the reverse).
- “We’ll sort SSEG later” with export already enabled.
- Prepaid exporter promises without naming the migration path.

Field notes from SA handovers
Bring this page to the commissioning visit. Ask the partner to demonstrate the behaviour described here, photograph the settings, and store them with the CoC and SSEG reference. When a future technician inherits your plant, that folder beats a WhatsApp voice note — choose installer · read a quote · selling with solar.
Also keep metro tariff PDFs and OEM warranty sheets dated. News headlines and brochure stickers age; annexures decide disputes. Cross-check fixed charges after SSEG so savings models stay honest — fixed charges · 2026/27 tariffs · metro tariffs hub.
Compare two quotes on one brief
Write roof photos, 12-month kWh, tariff code, Stage essentials and prepaid status once. Every partner returns on those assumptions — usable kWh, export-limit plan, CoC/SSEG scope, DB/meter lines. Related: check a quote · get quotes · red flags · CoC · SSEG.
Document pack to keep forever
- As-built single-line, serial list, OEM warranties.
- CoC, dual-supply label photos, SSEG / export letters.
- Monitoring logins and export-limit screenshots.
- Metro tariff code after any meter change.

Worked homeowner decision tree
- Photograph the bill header: Eskom vs metro logo and tariff code.
- Open the matching desk page on this site (Homeflex vs Cape Town vs City Power vs Tshwane vs eThekwini).
- Ask two installers which form they file and who books the meter — answers must match.
- Model savings with that desk’s fixed charges and export rules only — export vs self-use · zero-export.
Prepaid reality on both paths
Many export-capable products require conventional metering. Budget time and fees for migration before you celebrate feed-in cents — prepaid + solar · prepaid migration · bi-directional meters · timelines.
What does not change
CoC, dual-supply labelling, NRS-listed gear, earthing/SPDs and anti-islanding still apply. A “municipal special” that skips those is not a bargain — labels · SPDs · inspection fails · red flags.
Ownership checklist — eskom direct vs municipal solar sa
- Serial list and OEM portal registrations completed.
- Export-limit and SoC screenshots stored with the CoC.
- Insurance schedule updated within the insurer’s window.
- Two matched quotes archived even after you picked one — future claims and sales ask.

Export cents are not interchangeable
Cape Town net-billing cents, City Power feed-in, Tshwane credits, eThekwini network-access rules and Eskom Homeflex gen-offset are different instruments. Pasting any one of them onto the wrong bill invents savings. Keep the primary PDF dated next to your model — Cape Town · City Power · Tshwane · eThekwini · Homeflex gen-offset.
Installer briefing template (copy this)
- Supply authority: Eskom Direct / metro name.
- Tariff code photo attached.
- Prepaid or conventional.
- Export desired? Zero-export OK until meter?
- Who files SSEG and who books the meter appointment?
Two partners should return matching process answers. Divergence is a red flag — red flags · choose installer.
Practical next steps — eskom direct vs municipal solar sa
Write a one-page brief with 12 months of kWh or prepaid tokens, tariff code, roof photos, Stage essentials list and prepaid status. Send it to two installers. Compare usable kWh, export-limit plan, CoC/SSEG scope and Incl. VAT totals side by side — read a quote · check a quote · get quotes.
Store serials, warranty PDFs and dual-supply photos with the CoC. Update insurance. Re-check fixed charges after any meter change so the savings model stays honest — fixed charges · insurance · meters · selling with solar.
- Confirm NRS-listed gear where grid-interactive rules require it — NRS list.
- Refuse non-listed export hacks and undocumented DB work — red flags · DIY risks.
- Keep peer brand mentions factual: Freedom Won, Solar MD, BlueNova, BYD, Pylontech among others with named warranty or SKU facts only.
Timeline expectations differ by desk
Metro SSEG queues and Eskom Homeflex processing are not the same calendar. Ask for a realistic meter appointment window in writing and keep export limited until that window closes — SSEG timelines · export limits · meter cost.
Fixed charges after the tariff flip
Some homeowners see energy kWh drop while the fixed or network line rises. Re-run payback with the post-SSEG bill, not the pre-install token pace — fixed charges · bill still high · monthly savings.
Homeflex gen-offset vs metro net-billing — different maths
Eskom Direct Homeflex credits export on a TOU shape with booklet adders; metros such as Cape Town, City Power, Tshwane and eThekwini publish their own feed-in or net-billing cents and often force prepaid→conventional migration. Model the tariff you actually sit on — not a national average — Homeflex gen-offset · Cape Town cents · City Power · export vs self-use.
SSEG paperwork ownership
Direct customers still need lawful embedded-generator compliance and a bi-directional path if they want credits. Municipal customers add metro portals, inspection queues and fixed-charge surprises after the meter swap — SSEG · timelines · fixed charges · meters.
Bill-reading habit
Keep twelve months of statements before you size. Token buys on prepaid hide TOU shape until migration — read an Eskom bill · prepaid migration · bill still high.
Your supply authority sets the SSEG rules you follow
Eskom direct and municipal customers face different application forms, tariff books, and export rules. Design to the authority on your bill — not to a neighbour’s metro. Homeflex / Homepower vs City TOU changes the battery dispatch story entirely.
Put the tariff name and account authority on the first page of every quote comparison.
Put this topic’s operating rule on the plant-room card in one sentence. The next Stage 4 night is the wrong time to rediscover tribal knowledge.
Quick questions
Can I switch from municipal to Eskom Direct to get Homeflex?
Not as a casual homeowner trick — supply authority is a network fact, not a shopping preference.
Does solar work the same during load shedding?
Hybrid backup behaviour is similar; grid reconnection and export permissions still follow your supply authority rules.
Where do I start if my bill is confusing?
Photograph the bill header and tariff code; bring both to two installers on the same brief.
