Get Solar Installation QuotesThe Solar Installation Process
- Bill and load review. The installer looks at your kWh usage per month and which appliances you want running during outages.
- Site assessment. Roof type, orientation, pitch, shading, the condition of the distribution board and where the inverter and batteries can go.
- System design and quote. Inverter size, battery capacity, panel count and layout, with an itemised price.
- Municipal application. For grid-connected systems, the SSEG application goes to City Power, the City of Tshwane, the City of Ekurhuleni or Eskom. City Power and Tshwane expect approval before installation, so this step comes first.
- Installation. Roof mounting, panels, DC cabling, inverter and battery mounting, AC connection to the DB board, earthing and surge protection.
- Commissioning. Settings configured, battery communication checked, monitoring app set up and the system tested with and without the grid.
- Sign-off. Certificate of Compliance, commissioning report and the documents your municipality or Eskom needs to finalise registration.
How Long Solar Installation Takes
| Stage | Typical time |
|---|---|
| Site visit to written quote | 2 - 7 days |
| Equipment ordering | Same week, longer for specialist stock |
| Backup-only install | 1 day |
| Hybrid system, 5kW with panels | 1 - 2 days |
| 8 - 10kW or three-phase system | 2 - 4 days |
| Commercial rooftop array | 1 - 6 weeks depending on size |
| Municipal SSEG approval | Several weeks to a few months, depending on the utility's backlog; ask your installer |
Choosing the Right System Size
Size is driven by how much you use and what you want to back up. As a rough guide, each kilowatt of panels in Gauteng produces around 4.5 to 5 kWh a day averaged across the year, a little less in midwinter and on stormy summer days.
| Monthly usage | Typical system | Indicative installed price |
|---|---|---|
| Under 350 kWh | 3kW solar system | R55,000 - R85,000 |
| 350 - 700 kWh | 5kW solar system | R85,000 - R145,000 |
| 700 - 1,100 kWh | 8kW solar system | R140,000 - R210,000 |
| 1,100 kWh and up | 10kW solar system | R190,000 - R300,000 |

Compare Solar Installation PricesWhat Is Included in a Complete Installation
- Solar panels and mounting. Rails, roof hooks or clamps suited to your roof, and flashing where tiles are lifted.
- Inverter. Usually a hybrid inverter that manages panels, battery and grid together.
- Battery. Lithium iron phosphate (LiFePO4) is now standard for homes.
- Protection. DC isolators, AC breakers, surge protection devices and earthing.
- Changeover wiring. Splitting essential and non-essential circuits so backup power goes where you need it.
- Monitoring. An app or portal showing generation, usage and battery state.
- Paperwork. CoC, single-line diagram and SSEG documentation.
Gauteng Conditions That Affect Installation
- Summer storms. Afternoon thunderstorms from October to March cut generation on stormy days. Size batteries so a cloudy afternoon does not leave you short.
- Hail. Highveld hailstorms can crack glass. Use panels with a published hail rating and confirm your insurance covers the system.
- Lightning. Gauteng has some of the highest lightning activity in the country, so DC and AC surge protection and proper earthing belong on every quote.
- Roof orientation. North-facing is best. East and west roofs work well with slightly more panels.
- Approvals. Grid-connected systems, including battery systems that can connect to the grid, must be registered with City Power, Tshwane, Ekurhuleni or Eskom. See SSEG registration in Gauteng.
Common Installation Problems
- Undersized battery that runs flat before morning during long outages.
- Panels mounted where a neighbour's tree or a chimney shades them in the afternoon.
- Inverter installed in a hot, unventilated garage, shortening its life.
- Paperwork never submitted, which causes trouble when you sell the house.
- Essential circuits not split properly, so the geyser or oven drains the battery.

Solar Installation Questions
How much does solar installation cost in Gauteng?
A 5kW hybrid system with a lithium battery and panels typically costs R85,000 - R145,000 installed. Backup-only systems start from about R28,000, and larger 10kW systems run to R300,000 or more.
What size solar system do I need?
Check your monthly kWh usage. Under 350 kWh usually suits a 3kW system, 350 to 700 kWh a 5kW system, and higher usage an 8kW or 10kW system. An installer will confirm this against your roof and loads.
How long does solar installation take?
One to two days on site for most homes. Larger or three-phase systems take two to four days. Municipal approval runs separately.
Do I need batteries with solar panels?
Not always. A grid-tied system without batteries lowers daytime bills but switches off during outages. Batteries give backup and let you use solar power at night.
Can I add batteries later?
Yes, if the inverter is a hybrid model and the battery is compatible. Ask the installer to confirm which batteries the inverter supports before you buy.
Can I expand my solar system later?
Usually. Adding panels is limited by the inverter's PV input rating, and adding batteries by compatibility. Plan the inverter size for where you want to end up.
Do solar systems work during power outages?
Hybrid and off-grid systems with batteries do. Pure grid-tied systems without batteries shut down for safety when the grid goes off.
What approvals are required in Gauteng?
Grid-connected systems need a Certificate of Compliance and must be registered with City Power, the City of Tshwane, the City of Ekurhuleni or Eskom, depending on who supplies the property, using an inverter on the NRS 097-2-1 approved list.
