Commercial Solar engineered for Office Parks in Tunney
High Eskom tariffs and power instability directly affect office parks operations across Tunney, Germiston. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Tunney sit on the N3 corridor, where escalating utility recoveries per square metre make generation on site the lowest-risk hedge available.
Fully islanded generation for sites with weak, expensive or unavailable municipal supply, with generator fallback. 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 of Ekurhuleni account entirely.

Questions from Tunney operators
How long does a 500kW installation in Tunney take?
A 500kW plant on a office park in Tunney 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 Tunney, Germiston 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.
