What we do

Solar and backup power, done properly

Every system starts with an energy audit, so you pay for what your home or business actually needs.

Home solar

Grid-tied and hybrid systems sized to your household, so you cut your Eskom or municipal bill.

  • Panels, inverter and mounting
  • Monitoring app on your phone

Battery backup

Lithium battery storage that keeps lights, Wi-Fi, fridges and gate motors running through load-shedding and outages.

  • Expandable battery banks
  • Essential-load circuits

Commercial and farms

Larger installations for offices, workshops, schools and farms, from tens of kilowatts up to 1 MWh.

  • Peak-demand reduction
  • Phased roll-outs

Energy audits

We measure how and when you use power before recommending anything, so the system matches your real usage.

  • Usage and bill review
  • Written recommendation

Electrical compliance

Certificates of Compliance for property sales and new installations, plus SSEG registration with the municipality.

  • CoC inspections
  • Fault finding and repairs

Maintenance

Panel cleaning, system health checks and upgrades for new and existing installations, including ones we did not install.

  • Annual service plans
  • Battery and inverter upgrades

Indicative only, not a quote. Uses typical 2026 installed prices of about R9 500 per kW of solar and R4 000 per kWh of lithium battery, including installation and CoC. Assumes about R250 a month of fixed municipal charges that solar does not remove, that 80% of the solar you could use lines up with when you use power, 0.5% yearly panel ageing, and inverter and battery replacement in year 12 at 60% of today's price. Excess solar exported to the grid is not counted.
