Commercial solar, sized to your actual load

A farm is not a house with more panels. Motors, pumps, cold rooms, welders and tariff structures all change the design. We start with how you actually use power, then size the array, inverter and battery around it.

Farms and smallholdings

Borehole pumps, irrigation, cold rooms, workshop machinery, electric fencing, grain drying and household use on the same property. Most farms end up between 50 kW and 200 kW, with battery storage sized for the loads that must not stop.

  • Pump and motor starting considered, not just running watts
  • Ground mount on open land, or roof mount on workshops
  • Cable routing and trenching quoted properly

Businesses and warehouses

Shops, offices, workshops, cold storage, restaurants and manufacturing. Commercial tariffs reward shifting load into your own solar hours, and a battery turns that into overnight power and protection from outages.

  • Tariff analysis so the system pays back in the right order
  • Three-phase supply, single-phase backup or a mix
  • Phased implementation for larger sites
Commercial solar installation

Case study: 50 kW completed in Hoopstad

The operation ran on generators through long outages, and generator fuel was eating the margin. The brief was simple: keep the pumps, the cold room and the workshop running through a stage 4 evening, and stop paying Eskom for daytime production that the sun was providing anyway.

  • 50 kW inverter: three-phase hybrid, matched to the site's motor loads.
  • 51.2 kWh battery storage: overnight backup for essential circuits.
  • 40 solar panels: ground-mounted on open land.
  • Compliance pack and COC: handed over at commissioning.

Everything a compliant commercial system needs

No vague packages. Every commercial quote from RSA Solar Supplier itemises the equipment, the protection, the installation and the paperwork.

Inverter

A three-phase hybrid inverter sized to the array and to the site's peak and surge loads. For farms, motor starting current is the number that decides it, not the running wattage.

Battery rack

A rack-mounted lithium bank with ventilation, protection and a battery management system. Sized for the hours you need, not for the whole site.

Solar panels

Monocrystalline modules on properly engineered mounting, with rails, clamps and cable sized for the run length and temperature.

COC and compliance pack

Test certificates, warranties, installation records and the Certificate of Compliance for the electrical work, issued at commissioning. This is what your insurer will ask for.

Also included as standard: DC and AC protection (isolators, surge protection, earthing), cable and conduit allowances, monitoring setup so you can see generation and battery state of charge, a commissioning walkthrough with your staff, and after-sales support on WhatsApp.
