30kW engineered for Office Parks in Sandton
High Eskom tariffs and power instability directly affect office parks operations across Sandton, Johannesburg. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Sandton sit on the M1 corridor, where escalating utility recoveries per square metre make generation on site the lowest-risk hedge available.
Structuring your installation so the full renewable energy allowance is claimable in the year of commissioning. 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.

Questions from Sandton operators
How long does a 30kW installation in Sandton take?
A 30kW plant on a office park in Sandton 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 Sandton, 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.
