Backup is not the same as rooftop generation
A battery and inverter may supply selected loads without solar panels, while a rooftop PV system requires its own design, protective equipment and permission considerations.

Discuss your solar or backup system
Include your suburb, whether you already have an inverter or panels, your main backup priorities and any recent electricity-use information. Photos of the equipment labels can help.
Understanding the job
Understanding your power requirements
What to look out for
A solar installation and a backup-power installation solve different problems. Panels generate electricity when conditions allow; batteries store energy; an inverter manages conversion and distribution. Effective designs consider expected consumption, essential circuits and future expansion.
How we approach it
We begin with your goal: reducing purchased electricity, maintaining selected loads during outages or combining both. Load information, roof layout, shading, equipment location and existing distribution arrangements inform the next step and the quotation.
Technical perspective
System design, protection and commissioning
System performance varies with consumption patterns, roof orientation, weather and equipment. Any grid connection and approvals must follow the municipality’s applicable process and technical requirements. We will not publish unsupported savings or payback guarantees.
Practical guidance
Choose the system around the property
Solar generation and backup electricity solve related but different problems. Solar panels generate power when conditions permit; an inverter and battery arrangement can support selected circuits when the grid is unavailable. A sensible proposal starts by identifying appliances, their running and starting loads, when power is used and how long backup is required.
Roof condition, orientation, shading, cable routes, protection, inverter location and ventilation all affect installation planning. Panels alone do not guarantee uninterrupted power during an outage. System architecture, changeover arrangements and any municipal or utility requirements must be addressed before equipment is ordered.
Where an existing installation is being expanded, component compatibility and available capacity must be assessed rather than assumed. Customers should provide existing inverter and battery model details when available. We can then establish whether a repair, expansion or redesigned system is the appropriate next step.
What matters for your job
Design the right generation and backup arrangement before buying equipment
Roof space and shading affect output
Panels need suitable roof structure, fixing methods and exposure. A proposed panel count without a site assessment is only a preliminary indication.
Existing electrical equipment sets limits
Inverter capacity, battery compatibility, essential circuits, protection, grid interaction and commissioning documentation must be considered together.
What affects the quotation?
- Recent consumption or defined essential electrical loads
- Roof dimensions, shading, fixing access and existing equipment
- Permits/authorisations, isolation, commissioning and documentation needs
Safety and local requirements
The City of Cape Town requires applicable embedded-generation authorisation. A new system must not be treated as approved merely because panels or batteries have been installed.

Frequently asked questions
Helpful answers before you book
Will solar panels power everything in a power cut?
Not necessarily. Backup capability depends on system configuration, inverter and battery provision.
Can an existing inverter be upgraded?
Assessment is needed to establish equipment compatibility and safe electrical integration.
Do I need approval for grid-connected solar?
Applicable municipal rules and registration requirements must be checked for the proposed installation.
