100kW engineered for Hospitals in Clayville
High Eskom tariffs and power instability directly affect hospitals operations across Clayville, Olifantsfontein. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Clayville sit on the R21 corridor, where zero tolerance for supply interruption make generation on site the lowest-risk hedge available.
Backup engineering that keeps production lines, cold chain and POS systems running through Stage 6 schedules. Hospitals carry a load profile dominated by critical theatre, imaging and sterilisation load, 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 of Ekurhuleni account entirely.

Questions from Clayville operators
How long does a 100kW installation in Clayville take?
A 100kW plant on a hospital in Clayville typically takes 4 to 10 weeks from signed order, including structural assessment, City of Ekurhuleni SSEG paperwork and commissioning.
Do we need approval from City of Ekurhuleni?
Yes. Any grid-connected embedded generation in Clayville, Olifantsfontein 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 hospital account.
