30kW engineered for Office Parks in Longmeadow

High Eskom tariffs and power instability directly affect office parks operations across Longmeadow, Johannesburg. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Longmeadow sit on the N3 Modderfontein corridor, where escalating utility recoveries per square metre make generation on site the lowest-risk hedge available.

Steel-frame ground arrays for sites with spare yard or land, optimised tilt for maximum winter yield. Office Parks carry a load profile dominated by office-hours hvac, servers and lighting, 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: N3 Modderfontein corridor

Questions from Longmeadow operators

How long does a 30kW installation in Longmeadow take?

A 30kW plant on a office park in Longmeadow typically takes 4 to 10 weeks from signed order, including structural assessment, City Power SSEG paperwork and commissioning.

Do we need approval from City Power?

Yes. Any grid-connected embedded generation in Longmeadow, Johannesburg must be registered as SSEG. Reyds handles the full application, professional engineer sign-off and NRS 097-2-1 compliance documentation.

Can the system run our aircon and refrigeration during load shedding?

With hybrid inverters and LFP storage, cooling, refrigeration and commercial aircon can be carried through outages while also clipping peak-demand charges on your office park account.
