Industrial solar energy systems cut energy costs and improve uptime for factories, warehouses and high-load facilities. They combine rooftop or ground-mounted PV with three-phase inverters, switchgear and controls to supply heavy electrical loads, reduce demand charges and support essential plant systems. PowerPlus design and install industrial and commercial solar systems from their Johannesburg base and offer 24/7 support and compliance services.
What are industrial solar energy systems
An industrial solar energy system is a tailored photovoltaic installation built to serve larger electricity demands, often on three-phase networks. Systems include PV arrays, three-phase inverter banks, inverter and switchgear rooms, motor control centres or MCC integration, and optional battery energy storage for peak-shaving and backup. These systems are engineered to integrate with existing electrical distribution, including power factor correction and protection for heavy motors and process equipment.
Why you need a professional for industrial solar energy systems
Industrial installations carry safety, regulatory and continuity obligations. A professional team will: size three-phase solar correctly, design inverter and switchgear layouts, integrate with MCCs, include harmonic filtering and power factor correction where needed, and produce tender specs and drawings for procurement and compliance. Good design reduces downtime during installation and avoids costly changes during commissioning. PowerPlus provides full system design, power management and compliance services for industrial sites.
Why PowerPlus is the best choice for industrial solar energy systems
PowerPlus specialises in electrical and solar installations for industrial and commercial customers across Johannesburg. Their offering covers initial feasibility, design, installation and ongoing maintenance, plus Certificates of Compliance for electrical work. That combination keeps projects on schedule, and ensures installations meet local safety and grid requirements.
Typical industrial services we provide
We start with a site survey and load analysis to define scope and expected savings, then produce procurement-ready technical drawings and a bill of materials. Our team manages three-phase electrical integration, MCC coordination, safety compliance and ongoing monitoring so the installation delivers reliable uptime and the returns you expect.
- Site feasibility and load profile analysis, including peak demand and tariff review.
- Detailed system design with three-phase inverter selection and inverter and switchgear schedules.
- MCC integration, motor protection, and interlocks for production lines.
- Battery energy storage and peak-shaving strategies, with BESS layout and control logic.
- Power factor correction, harmonic mitigation and tender specs for procurement.
Use this single list to summarise core deliverables and aid procurement planning.
How industrial solar energy systems process works
Each project follows defined stages from assessment to handover, with engineers and project managers assigned at every step. We coordinate approvals, procurement and three-phase integration on site to minimise disruption, and supply test reports, compliance certificates and handover documentation.
- Feasibility study. We analyse your bills, load profile and site constraints to recommend capacity, payback and tender specifications.
- Design and specification. Engineers produce single line diagrams, inverter and switchgear schedules, MCC integration notes, and a bill of materials.
- Approvals and procurement. We prepare tender specs for panels, three-phase inverters, batteries and switchgear, and guide approvals with the local authority and utility.
- Installation and integration. PV arrays, inverters, switchgear and any MCC modifications are installed, commissioned and tested to O&M standards.
- Handover and O&M. We issue compliance documentation and offer maintenance and monitoring to protect yield and uptime.
Design and commissioning follow recognised South African industry and O&M best practice to ensure reliable operations.
Get an industrial solar feasibility study
Start with a practical feasibility study to know what industrial solar energy systems will deliver for your operation. PowerPlus will review recent electricity bills, your peak loads and site constraints, and produce a clear proposal with expected savings, payback and a tender spec you can use to procure equipment. The study includes options for three-phase solar, battery energy storage for peak-shaving, and power factor correction where beneficial.
FAQs
What size of system does industrial sites typically need?
Sizes vary with consumption, but industrial systems are scaled to meet a portion of daily energy use and to reduce peak demand, rather than to run all loads off solar alone. A feasibility study gives the correct sizing.
Do industrial solar systems work on three-phase supplies?
Yes, industrial PV uses three-phase inverters and balanced array layouts to integrate directly with factory supplies, protecting motors and process equipment.
Can I add batteries for backup and peak-shaving?
Yes, battery energy storage is commonly paired with industrial systems to shave peaks, support critical loads during outages, and improve self-consumption. Designs include BESS layout, controls and safety systems.
Will solar affect my MCC or motor controls?
If your site has large motor loads, MCC integration is essential. Engineers coordinate inverter and switchgear connection points, protection relays and control logic so motors and MCCs continue to operate reliably.
How does power factor correction help my solar project?
Improving power factor can reduce demand charges and the size of the required PV or battery system. Many industrial clients recover PFC costs quickly, making the overall solar project more cost effective.
Do you provide tender specs and drawings?
Yes, PowerPlus prepares the technical specifications, single line diagrams and schedules needed for tendering and procurement, ensuring bidders supply compatible inverters, switchgear and batteries.
