100kW engineered for Auto Dealerships in Fourways

High Eskom tariffs and power instability directly affect auto dealerships operations across Fourways, Johannesburg. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Fourways sit on the William Nicol corridor, where showroom uptime and EV charging demand make generation on site the lowest-risk hedge available.

End-to-end Small-Scale Embedded Generation applications with your municipality or Eskom distribution office. Auto Dealerships carry a load profile dominated by showroom lighting, workshop compressors and ev chargers, which is exactly where solar generation overlaps hardest with your billing peaks.

Pair your cooling, refrigeration and commercial aircon systems directly with solar PV generation to cut high peak-demand electrical charges. Thermal pre-cooling during peak irradiance hours shifts chiller demand off the City Power account entirely.

Local grid and industrial context

  • Distribution authority: City Power, feeder capacity confirmed before design freeze
  • Industrial corridor: William Nicol corridor
  • Fourways Mall precinct
