Solar in Pretoria: 2026 Cost, Payback & City of Tshwane Rules
Verified install prices, City of Tshwane SSEG rules, real solar yield data, sample bill walkthrough, common mistakes, step-by-step process. Updated April 2026.
The Pretoria solar story
Tshwane currently bans reverse feed entirely - if your solar overproduces, the excess is wasted (no battery? worse, the inverter throttles). This is the inverse of Cape Town. Sizing matters: bigger ≠ better in Tshwane unless you also size battery to absorb everything.
Sample bill walkthrough: a typical Pretoria home
Real-world numbers for a household currently spending around R4,000/month on electricity in Pretoria. We use the 5 kVA kit at the mid-range install price.
| Current monthly Eskom / municipal bill | R4,000 |
| 5 kVA install (mid-range) | R117 000 once |
| Monthly bill after solar | R1,700 |
| Monthly Eskom savings | R2,300 |
| Estimated payback | 7 years |
Worked example. Your actual numbers depend on your roof orientation, daytime consumption pattern, installer quote, and battery sizing decisions. Use the calculator to get a tailored estimate: Solar Savings Calculator →
Solar sizes & payback in Pretoria
Annual return (bill savings + SSEG income) and payback period for each kit tier in Pretoria. Assumes 85% self-consumption, 15% exported to grid where buyback applies.
| Kit | Mid-range cost | Annual gen | Bill savings/yr | SSEG/yr | Payback | |

| 8 kVA | R192 000 | 6,440 kWh | R22 389 | — | 8.6 yrs | Details → |

Monthly solar generation curve in Pretoria
How a 5 kVA install (4 panels, 1.84 kWp) generates across the year in Pretoria. Annual total: 3,220 kWh. Bars are roughly to scale - October to March is your strongest production, June to August your weakest.
Numbers in kWh on each bar. Calculated from Pretoria’s 1750 kWh/kWp/year yield distributed across the typical SA seasonal curve - production is highest mid-summer (October-December), lowest mid-winter (June-July).

Common mistakes specific to Pretoria
What we see go wrong on Pretoria solar installs. Some are universal mistakes, some are local to the city’s climate, geology, or municipal rules.
- Oversizing panels expecting future buyback. Tshwane currently bans reverse feed - bigger panel array than your battery + daytime use can absorb is wasted production.
- Skipping the Embedded Generation Policy registration. Even own-consumption installs need to be registered with the City - non-registration can void your installation's legal status.
- Buying a hybrid inverter without configuring "no export". Default settings on most hybrid inverters allow grid feed-in - this is a compliance issue in Tshwane.
- Assuming SSEG rules will change "soon". The City has been signalling review for 2+ years without action. Plan for the rules as they are today.

Frequently asked questions about solar in Pretoria
Can I sell solar power back to City of Tshwane?
Tshwane is the worst SSEG city of the four covered. Per the City's 2025 Embedded Generation Policy, "reverse feed into the distribution network may not take place" and only SSEG customers who remain net consumers (averaging more grid-buy than solar-export over 12 months) are permissible. In practice this means: install solar, but size it to your own consumption - excess is wasted. No financial buyback exists.
How long does solar take to pay back in Pretoria?
A typical 5 kVA solar + battery install in Pretoria pays back in approximately 6 years. Solar yield is 1750 kWh per kWp per year. Combined with the upper-block City of Tshwane tariff of R4.09/kWh, a 4-panel kit (~1.84 kWp) generates roughly 3,220 kWh/year worth approximately R11 194 in bill savings annually.
What is the solar yield in Pretoria?
Solar yield in Pretoria is 1750 kWh per kWp per year - 1 kWp of installed panels (roughly two 460W panels) generates 1750 kWh of electricity over a year on a north-facing roof at typical tilt. Cape Town has the highest yield in SA at ~1,900 kWh/kWp/year; Durban has the lowest at ~1,650 kWh/kWp/year.
What size system do I need in Pretoria?
For an Eskom bill of around R4,000/month, the typical right-fit is the 5 kVA inverter + 10 kWh battery + 4 panels costing roughly R117 000. After install, expect your monthly bill to drop to about R1,700, saving R2,300/month. Pages with detailed sizing: see the size pages below.
What does Pretoria solar cost in 2026?
2026 prices in Pretoria: 3 kVA backup R48 000-R80 000, 5 kVA mid-tier R90 000-R145 000, 8 kVA large R150 000-R235 000, 15 kVA premium R280 000-R430 000. Always get 3 quotes - the spread between cheapest and most expensive on the same kit is typically 25-40%.
Updated 28 April 2026. SSEG figures from City of Tshwane’s 2025/26 approved tariff document; rate expires 30 June 2026 and is reviewed annually. Solar yield from PVGIS / Western Cape Government solar map. Tariffs from each metro’s public tariff schedule.
