As South African businesses continue to face energy uncertainty and escalating electricity costs, solar energy has become more than a sustainability initiative – it is a strategic business decision. The question is no longer whether to go solar, but how to make the most out of their installation.

Solar power solutions provider SolarEdge’s DC-optimised inverter solution is already helping thousands of South African businesses such as Ford, Volkswagen and Massmart, to unlock greater energy savings, enhanced safety, and storage integration - far beyond what traditional string systems can offer. SolarEdge’s solution is exclusively the only optimised solution available in South Africa*^[1].

Why Traditional String Inverters Fall Short

Conventional string systems connect multiple solar panels in series. The downside? The entire string’s performance is limited by the weakest panel. If one panel is shaded, dirty or underperforming, energy production of the entire system suffers.

This is especially problematic in South Africa, where:

• Rooftops are often irregular or partially shaded
• Dust and debris can accumulate quickly
• System uptime is critical for business continuity.

Optimised for South African Business Needs

SolarEdge’s Module-Level Power Electronics (MLPE) architecture, powered by Power Optimisers, transforms each solar panel into a smart energy producer. Unlike string systems, each panel operates at its maximum potential, regardless of the performance of neighboring panels.

Direct business benefits are:

• More energy in shaded/dusty conditions
• Higher return on investment through improved energy yield
• Reduced downtime with real-time monitoring
• Flexible design for complex rooftops and solar array expansions
• Compliance with PV safety standards and fire mitigation.

Design Freedom for Complexed Sites

South African commercial buildings often have multiple roof orientations, obstructions like HVAC units or skylights and limited space for solar arrays.

SolarEdge’s MLPE architecture allows panels to face different directions and tilts, for maximum rooftop utilisation and easy system expansion as energy needs grow.

This is ideal for retail centres, warehouses, factories and office parks.

Safety First: Protecting People, Property and Profits

Electrical safety is a key concern in solar installations. SolarEdge’s built-in SafeDC™ technology is designed to automatically reduce voltage to touch-safe levels during emergencies, maintenance, or inverter/grid shutdowns. This is critical for fire safety compliance, insurance requirements and protecting staff and first responders.

In contrast, traditional string systems maintain high DC voltage during daylight hours even when the inverter is off, which could pose a serious risk.

Smart Monitoring = Smart Business Decisions

SolarEdge’s cloud-based monitoring gives you real-time visibility into every panel’s performance. For business owners, this means:

• Faster, pinpointed fault detection
• Remote troubleshooting
• Lower maintenance costs.

You’ll know exactly how your system is performing down to the panel level - so you can make informed decisions and maximise uptime.

Storage-Ready for More Energy Independence

One of the biggest advantages of SolarEdge is its seamless integration with battery storage. With the SolarEdge Commercial Storage System, businesses can:

• Store excess solar energy for use when needed
• Power critical operations during loadshedding
• Shift energy usage to off-peak times.

This is a game-changer for industries like manufacturing, logistics and retail, where power continuity is essential.
