Solar in Johannesburg

Johannesburg sits high on the Highveld, so it enjoys clear skies and strong sun for much of the year, with dry winter days that are cold at night. Most of the city is supplied by City Power, with Eskom serving some areas and Soweto, and grid-tied and hybrid systems need to be registered and approved before connection. Houses have concrete tile or IBR roofs, while apartment blocks, offices and warehouses have flat or sheeted roofs suited to large arrays. Afternoon thunderstorms bring hail and lightning, so strong mounting and surge protection matter. Hybrid backup for load-shedding, solar geysers and commercial rooftop systems are all in demand across the northern and southern suburbs.

Typical off-grid solar systems requests in the area come from:

  • Family homes: rarely fully off-grid, though some owners go grid-free with large battery banks and a generator
  • Estate homes: occasional off-grid homes where the estate allows it, with ground or roof panels and generous storage
  • Townhouses and flats: seldom suitable for townhouses, though off-grid common-area lighting or gate systems are sometimes installed
  • Shops, offices and schools: remote shops, guest lodges and rural clinics that need steady power where the grid is unreliable
  • Factories and warehouses: mines, remote sheds and pump stations running on dedicated solar, battery and generator systems
  • Farms, smallholdings and lodges: farmhouses, labour housing and lodges far from the grid, often powered with a generator backup

Why get a quote in Johannesburg first?

No two solar jobs in Johannesburg are the same. A quote based on your details shows the real cost of the panels, inverter, batteries, mounting, cabling, protection, labour, the Certificate of Compliance and registration, so you can budget properly and avoid surprises.

What to include in your request

  • List every appliance and how long it runs each day.
  • Say which is the largest motor to start, such as a pump.
  • Describe the site: roof, open ground, coast or inland.
  • State how many cloudy days of storage you want.
  • Mention if a generator already exists and its size.

The more detail you give, the more accurate your quote will be.

Service area: Johannesburg and surrounds

Installers on our network work in Johannesburg and surrounding areas, including Rosebank, Melville, Booysens, Selby, Edenvale, Sandton, Roodepoort. Give your suburb in the request so the person quoting can allow for travel and plan a site visit to look at the roof and the distribution board.

Frequently asked questions

What will it cost in Johannesburg?
It depends on the size of the system, the equipment chosen, the roof, the distance from the inverter to the distribution board, the paperwork for your electricity supplier and how soon you need it done. Tick your loads on the form and a solar installer working in Johannesburg will quote you.
Will someone come out to look at the property?
Yes, for most jobs. The person quoting needs to see the roof, its direction and shading, the distribution board and where the inverter and batteries will go. Give your suburb on the form and they will arrange a visit.
How much sun is there in Johannesburg?
A north-facing array in Johannesburg makes about 5.2 kWh per kWp a day averaged over the year. Shade from trees or neighbours, the roof angle and dust change this, so the installer will check your roof.
