Solar in Cape Town in 2026: costs, payback, feed-in tariff and SSEG rules

First Energy Solar Solutions

Last updated September 2026. Tariff figures are from the City of Cape Town’s 2026/27 tariff book (1 July 2026 – 30 June 2027) and include VAT.

Cape Town is the best-positioned city in South Africa for rooftop solar: high sunshine hours, a municipality that pays for exported power, and electricity tariffs that have climbed every single year. This guide gives you the real numbers before you ask anyone for a quote – including us.

1. Why 2026 is different from 2023

Three years ago people bought solar to survive load shedding. Load shedding has now been suspended for more than a year, and the reason to install has shifted to the bill:

City of Cape Town Domestic customers pay R4.14 per kWh for the first 600 units a month and R4.94 per kWh above that from 1 July 2026. The overall average increase was 6.67%.
Eskom Direct customers saw an 8.76% increase on 1 April 2026.
Fixed charges are rising faster than energy charges. The City’s Domestic service charge went up 8.54% this year.

Every unit your roof produces is now worth up to R4.94 that you don’t buy. That is the whole business case.

2. What a system costs in Cape Town (2026)

Typical installed prices for a quality hybrid system (panels, inverter, lithium battery, mounting, installation, CoC and SSEG registration):

System	Suits a monthly bill of	Typical installed price
Inverter + 5 kWh battery, no panels (backup only)	any	from R55,574
3.3 kWp panels, 5.5 kW inverter, 5 kWh battery	R1,500 – R2,500	from R92,017
4.4 kWp, 5.5 kW inverter, 10 kWh battery	R2,500 – R3,500	from R115,154
5.5 kWp, 8.8 kW inverter, 10 kWh battery	R3,500 – R5,000	from R155,385
7.7 kWp, 12 kW three-phase inverter, 15 kWh battery	R5,000+ / small business	from R214,400

These are our current Green, Silver, Gold, Platinum and Premium packages. Beware of quotes well below this. The usual reasons are an inverter that is not on the City’s approved list (so it cannot be registered), a battery with a short cycle life, undersized cabling, or no CoC. Our Best Price Guarantee exists precisely so that you can compare like with like.

3. How fast it pays back

Cape Town yields roughly 1,800–1,950 kWh per year for every 1 kWp of panels on a north-facing roof. A 5.5 kWp system therefore produces about 10,000 kWh a year.

Worked example, household on the Home User tariff spending R3,500 a month:

Self-consumed solar (about 70% of production): ~7,000 kWh × ~R4.50 average = ~R31,500 a year saved
Exported solar (about 30%): ~3,000 kWh × R1.53 = ~R4,600 a year credited
Total benefit ≈ R36,000 a year, against an installed cost of about R155,000
Simple payback ≈ 4.3 years, then 15+ years of near-free daytime electricity.

Add battery-shifted evening usage and the annual tariff increases and most Cape Town homes land between 3.5 and 5.5 years. Businesses that can claim the Section 12B deduction typically come in under 4 years (see tax incentives).

4. What the City pays you for exported power

Registered grid-tied customers earn the residential SSEG feed-in tariff of about R1.24/kWh plus a 28.75c/kWh incentive – roughly R1.53 per exported unit in 2026/27. Credits offset your electricity, then the rest of your municipal account; under Cash for Power the City pays out the remaining balance (households once a year above R1,000, businesses monthly above R5,000).

Two things to know:

You must be on the Home User tariff to register solar. It has a fixed service and wires charge of about R424 a month but lower per-unit rates.
The feed-in rate is reviewed every July. Design the system to pay back on self-consumption; treat export as a bonus.

5. The rules: SSEG registration in Cape Town

Every solar PV or battery system in the City’s supply area must be authorised before installation – it is a by-law requirement, and unregistered systems can void your household insurance.
Applications are made online on the City’s Energy Services e-Services platform.
Only City-approved inverters are authorised.
Since October 2023 all new applications are processed as grid-tied.
Exporting requires a bi-directional AMI meter.

First Energy prepares and submits the application, supplies the engineering sign-off and follows it through to written authorisation. How SSEG registration works.

6. Buy, finance, rent-to-own or subscribe?

Cash: lowest lifetime cost, fastest payback.
Bank finance: we are an approved installer for Standard Bank Business Solar and Nedbank Residential Solar.
Rent-to-own: 3-, 4- or 5-year plans; you own the system at the end. Compare packages.
Subscription/rental: low entry price (from about R1,200 a month for a small system elsewhere in the market) but you never own it and the payment does not fall when tariffs rise. Rent-to-own vs subscription.

7. Which brands hold up in Cape Town conditions

Salt air, winter storms and hot roofs punish cheap equipment. We install and support Sunsynk, Deye, GoodWe and Fox ESS inverters, BYD and Fox batteries, and JA Solar glass-on-glass panels – chosen for local distributor support, spares and warranties, not just price. Our brands.

8. Questions to ask any installer

Is the inverter on the City of Cape Town approved list?
Who signs the CoC, and will you submit the SSEG application for me?
What is the battery’s warranted cycle life and depth of discharge?
Is the design based on my actual usage profile or just my bill?
Who do I phone in year six when something needs attention?
Do you carry public liability and do your installers work at height legally?

Frequently asked questions

How much does a 5 kW solar system cost in Cape Town in 2026?
A properly installed 5 kW hybrid system with a lithium battery costs roughly R150,000–R160,000 including SSEG registration and CoC. Smaller 3 kW systems start around R92,000.

Do I still need a battery if there is no load shedding?
Not for the savings case – a grid-tied system without a battery still cuts your bill. A battery lets you use your own solar in the evening (worth R4.94/unit instead of R1.53 exported) and covers local outages and load reduction.

Can I sell electricity back to the City of Cape Town?
Yes. Registered, grid-tied systems with an AMI meter earn about R1.53 per exported kWh in 2026/27, and the City pays out cash once your account is fully offset.

Is there a tax rebate for home solar?
No. The 25% residential rebate ended on 29 February 2024. Businesses can still deduct 100% of a system under Section 12B.

How long does installation take?
A typical home system is installed in one to two days. SSEG authorisation from the City is the longer step – allow 2–4 weeks. We start the application as soon as you accept the quote.

Does First Energy install outside Cape Town?
We cover the whole Western Cape. Eskom Direct customers follow Eskom’s registration process, which we also handle.
