How we work

  1. 1

    Understand your usage

    We look at your bills, loads and site, and where needed install a temporary meter to measure day and night demand.

  2. 2

    Engineer the design

    Panels, inverter and batteries sized to the property, with a clear quote and room to expand later.

  3. 3

    Install and certify

    Our own team installs, tests and commissions the system, and issues the electrical CoC.

  4. 4

    Register and support

    We handle the SSEG paperwork with the City and stay on hand after the job is done.

In a time where good service is rare, excellent service really stands out. From the design phase to the construction phase, they were always forthright, reliable and efficient. The owner still texts me when he sees power issues in the area or if he has updates for my system. Customer care second to none.

Common questions

How much does solar cost in Cape Town?

It depends on system size, battery storage and how you use electricity. We design each system around the property and give you a detailed quote after assessing your needs.

Does solar work during load shedding?

A grid-tied system shuts down when the grid is off. A hybrid system with batteries keeps your essential circuits powered.

Can batteries be added to my existing system?

Often, yes. We assess what you have and recommend the most suitable upgrade.

Do I need SSEG approval?

Grid-connected systems in Cape Town must be registered with the City. We advise on what applies to you and handle the application. More on SSEG.
