For several years, the case for solar in South Africa was simple: the lights kept going out. With load shedding largely absent for more than a year now, a fair question is whether the case still stands. If you are asking is solar worth it without load shedding, the honest answer is that it depends on what you were buying solar for in the first place.
What has actually changed
Eskom reported a long run of days without load shedding heading into winter 2026, crediting its generation recovery plan and a drop in unplanned outages. That is a genuine improvement for businesses that were losing production, stock and revenue to outages.
But two things are worth keeping in view:
- Load reduction continues in some areas:
Eskom has been working to remove affected feeders from load reduction schedules, but it is a gradual process and some areas still experience scheduled interruptions. - Outages are not only about generation:
Local network faults, cable theft, municipal infrastructure failures and maintenance shutdowns still interrupt supply regardless of the national load shedding stage.
The savings case does not depend on outages
The most durable reason to go solar was always financial. Eskom direct customers have already experienced an approved average increase of 8.76% from April 2026, while municipal bulk purchasers faced an average increase of 9.01% from July 2026. Looking ahead, Eskom has proposed a further average increase of 8.83% for direct customers from April 2027, subject to NERSA approval. We cover the detail in our post on the 2026/27 electricity tariff increase.
Solar generation is priced at a rate agreed upfront, so the longer tariffs keep climbing, the wider the gap between what you would have paid and what you do pay. That gap exists whether or not the grid is under strain.
Three questions to test your own case
1. How much of your consumption happens in daylight?
Solar is particularly effective for businesses with significant daytime electricity consumption, typically during normal operating hours. Examples include schools, offices, packhouses, light manufacturing and retail operations. If your load is mainly at night, the savings are smaller unless you add storage.
2. What does an outage actually cost you?
For a farm with cold storage or a school with a server room and boarding facilities, a few hours without power can be expensive. If outages cost you little, you may not need batteries at all, and a solar-only system can still be worthwhile on tariff savings alone.
3. Can you avoid the upfront cost?
This is where many sound business cases stall. A funded model removes the capital outlay, so you can capture the savings without competing against other budget priorities. Read more on how no-capex solar works.
Solar only, or solar plus storage?
Without frequent load shedding, many businesses find a solar-only system gives the strongest return, because batteries add cost. Storage still makes sense where:
- Critical loads cannot tolerate any interruption (cold chain, medical, IT)
- You are on a tariff with steep peak pricing and want to shift consumption
- You want to reduce reliance on a diesel generator
Our battery storage sizing guide walks through how to decide.
FAQ: Is solar worth it without load shedding
Do I need batteries if there is no load shedding?
Not always. A solar-only system can deliver strong savings if most of your power is used in the day. Batteries make sense where outages are costly or you want to shift usage.
Will my solar rate stay fixed?
That depends on the agreement. Some rates are fixed and others escalate annually, so ask how the rate changes and compare it with expected grid increases.
The bottom line
Solar is still worth considering without load shedding, but the reason has shifted. It has moved from “keep the lights on” to “control a cost that is rising faster than inflation”. If your consumption is mostly in the daytime and you can structure the project without a large upfront spend, the case remains strong.
