Aircon & HVAC Thermal Solar Integration engineered for commercial and industrial facilities in Midrand
High Eskom tariffs and power instability directly affect commercial and industrial facilities operations across Midrand, Johannesburg. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Midrand sit on the N1 Ben Schoeman corridor, where rising demand charges and outage risk make generation on site the lowest-risk hedge available.
Coupling chillers, refrigeration and commercial aircon directly to PV generation to flatten peak-demand charges.
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.

Questions from Midrand operators
How long does a 500kW installation in Midrand take?
A 500kW plant on a facility in Midrand 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 Midrand, 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 facility account.
