Backup Power Systems for Johannesburg homes and businesses

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 backup power systems requests in the area come from:

  • Family homes: a wall-mounted inverter and lithium battery keeping lights, Wi-Fi, fridge and gate motor on during outages
  • Estate homes: larger home systems with neat battery cabinets that meet estate rules and cover security and fibre during outages
  • Townhouses and flats: compact inverter and battery units for flats and townhouses, often needing body corporate approval
  • Shops, offices and schools: battery backup for tills, card machines, servers, alarms and lights so trading carries on during load-shedding
  • Factories and warehouses: three-phase backup for controls, cold chain and security, with generator integration for essential production
  • Farms, smallholdings and lodges: backup for homesteads, milk tanks, pumps and security, usually with generator support for long outages

Why get a quote in Johannesburg first?

Taking the first price you hear can cost more over the life of the system. By requesting a quote for Johannesburg, you can check the equipment, the warranties, the after-sales support and whether registration is included, and find a solar installer you can call again.

What to include in your request

  • List the appliances you must keep running
  • Say how long outages usually last for you
  • Note single or three phase supply
  • Say if you want to add solar later
  • Mention where batteries could be mounted

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

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.
