Residential Solar for Southern African Homes
Solar and battery systems are designed around your home's energy use, helping reduce grid dependence, lower electricity costs, and keep essential appliances running during outages.
Local outages, municipal faults, and rising electricity tariffs continue to affect households across South Africa. Regardless of the national load shedding schedule, South African households don't need to wait for national load shedding to return before considering solar. A correctly sized residential solar and battery system keeps essential circuits running through an outage and caps how much of your bill is exposed to future tariff increases.
Reduce Home Energy Costs with Solar and Battery Storage
National load shedding has paused, but that has not translated into reliable power for most households. Local outages, municipal infrastructure faults, and load reduction continue to interrupt daily life, and electricity tariffs keep rising regardless of how much power gets delivered.
Solar and battery storage address both problems at once: it keeps essential circuits running when the grid fails, and it reduces how much of your bill is exposed to future tariff increases.
Electricity costs are also changing. Eskom’s approved 2026/27 tariffs increased by an average of 8.76% for directly supplied customers, while municipal bulk tariffs increased by 9.01%, although the impact on individual households varies by municipality and tariff.

Reliable Solar Power for Southern African Homes
South African homes are reported to lose power an average of 6 to 9 times a month, according to Wetility data, even with national load shedding paused, a mix of local outages, municipal faults, and load reduction that a grid-tied-only system can’t protect against.
The second issue we come across is cost: fixed charges, network capacity charges, and annual tariff increases mean your bill can rise even in a month where you used less electricity than before.
Solar and Battery Storage for Uninterrupted Home Power
A modern residential solar system pairs solar panels with a hybrid inverter and a lithium battery. During the day, solar can power the home and charge the battery. During an outage, the system can automatically supply the circuits configured for backup, depending on the inverter, battery capacity, and system design.
How much solar and battery storage does your home need?
Sizing depends on your daily consumption (in kWh) and which appliances you want to keep running during an outage. A small household protecting lights, Wi-Fi and a fridge needs a much smaller system than a household wanting to run an entire home, including a geyser and air conditioning, through a multi-hour outage.
Getting this step wrong, either under-sizing or over-spending on a system larger than you need, is one of the most common and costly mistakes homeowners make.
Our quotes are based on your consumption, historical usage, peak demand, essential versus non-essential loads, and how long you want backup to last. A properly designed residential system should be based on your actual consumption and backup requirements, rather than a standard package size.
Why residential solar still matters
Wetility’s 2025 telemetry data, reported by Engineering News, recorded more than 91,000 grid outages across its customer network in 57 South African municipalities, with customers experiencing an average of six to nine outages per month.
Residential Solar Costs and Financing
The cost of a home solar system depends primarily on system capacity, battery storage, backup requirements, installation complexity, and the equipment selected.
From Home Energy Assessment to Solar Installation
- Energy Assessment, understanding your household consumption and priority loads.
- Site Assessment: checking roof space, orientation, and structural suitability.
- System Design: sizing the panels, inverter, and battery to match your energy use.
- Transparent pricing based on your unique design.
- Installation: Most residential systems are completed in a few days once a quote is confirmed.
- Commissioning: the system is tested and switched on.
- Ongoing Support.
Choose a Residential Solar Installer You Can Trust
Price is an important factor, but track record is more important. An accredited installer with a local presence, verifiable project history, and transparency about the components used always provides a safer and more affordable system in the long run, one that does not break or need fixing in year two.
A cheap system from an installer who disappears after commissioning is rarely the saving it first appears to be.
Solar vs Generators vs Inverter Backup Systems
These three solar options solve the same problem in very different ways. A generator is noisy, needs fuel, and requires manual starting in most cases.
A plug-in inverter is cheap but only carries a handful of circuits for a few hours.
A solar and battery system costs more upfront but runs automatically and silently and scales to cover as much of your home as you choose, while also reducing your day-to-day bill.

Avoid Costly Mistakes When Choosing Home Solar
The most common costly mistakes are buying on price alone without checking the installer's track record, under-sizing the battery for the loads that matter, and not confirming warranty terms on batteries specifically, since battery warranties are typically shorter than panel warranties.

Frequently Asked Questions
Is residential solar still worth it now that load shedding has paused?
South African households still face unexpected outages, rising electricity tariffs, and increasing fixed charges, making solar and battery storage a practical way to improve energy security and reduce reliance on the grid.
How long does it take to install a home solar system?
Once a site assessment and quote are confirmed, most residential installations are completed within a few days, though timelines vary with system size and any required approvals. See our installation process guide.
Can I start small and add battery capacity later?
In most cases, yes, but it depends on the inverter and battery brand chosen. This is worth confirming with us at the quote stage if the budget is a concern now, but you expect to expand later.
