100kW engineered for Warehouses in Modderfontein

High Eskom tariffs and power instability directly affect warehouses operations across Modderfontein, Johannesburg. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Modderfontein sit on the N3 corridor, where vast unused roof area and rising fixed demand charges make generation on site the lowest-risk hedge available.

NRS 097-2-1 compliant grid-tied photovoltaic plant engineered to offset daytime consumption without export penalties. Warehouses carry a load profile dominated by daytime lighting, forklift charging and dock equipment, 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 Eskom account entirely.

Questions from Modderfontein operators

How long does a 100kW installation in Modderfontein take?

A 100kW plant on a warehouse in Modderfontein typically takes 4 to 10 weeks from signed order, including structural assessment, Eskom SSEG paperwork and commissioning.

Do we need approval from Eskom?

Yes. Any grid-connected embedded generation in Modderfontein, 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 warehouse account.
