Hi, a 5 kW system with a battery is about R 74,500 installed in Johannesburg. Does your roof face north, and do you already have a grid connection?

Cape Solar Crew

Hi, we install backup systems from about R 74,500 for 5 kW. Which phase supply do you have, and when do you need the work done?

Registration and rules

Eskom registration for home solar has been free for most households, but the sources disagree on whether a fee applies after March 2026, so check the current rule with Eskom before you sign. The sources also say a solar installation must be done by a registered electrical contractor, and that a Certificate of Compliance is legally required. Ask the installer for both.

Season and load-shedding

Summer, December to February, has the longest and sunniest days, so solar output is strongest then. Backup power matters most during load-shedding, so ask how long the battery keeps the essential circuits running through the night.

How systems are priced here

Prices are given per panel, per kW of inverter and per kWh of battery capacity, and installation is a separate line. Ask whether the quote includes mounting, cabling, the Certificate of Compliance and any grid connection work. Say which city you are in: Johannesburg, Pretoria, Cape Town, Durban or Gqeberha.

What to write in the request

State the system type, the power in kW, the battery capacity in kWh, the number of phases, the roof or site address, your deadline and your budget. Add whether you want backup only or a system that feeds into the grid.

BlaBlaPrice reads your request, asks for missing details such as roof size and phases, and checks installers' price lists in South Africa. Installers registered on BlaBlaPrice reply in the chat with their price and terms, and your contact details stay hidden until you choose to share them.
