Section 12B Tax Optimization engineered for commercial and industrial facilities in Durban
High Eskom tariffs and power instability directly affect commercial and industrial facilities operations across Durban, eThekwini. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Durban sit on the N3 Durban to Gauteng corridor, where rising demand charges and outage risk 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.
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 eThekwini Metro account entirely.

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