Section 1: Introduction

Present the topic of the article by stressing that optimal system performance begins with quality installation and is sustained through disciplined maintenance.

Why It Matters:

• Poor installation and maintenance practices are among the leading causes of energy losses, safety risks, and shortened system lifespans.

• In South Africa, with its unique climate and energy reliability challenges, adhering to best practices is even more critical.

• Focus: This blog post outlines seven key best practices to ensure commercial solar PV systems deliver long-term value, safety, and return on investment.

Section 2: Best Practices for Installation and Maintenance

1. Ensure Safe and Code-Compliant Installation

Regulatory Requirements:

• Adhere to SANS 10142 for electrical installations and NERSA Grid Code for grid-tied systems.

• All commercial installations must obtain an Electrical Certificate of Compliance (COC).

• Best Practice: Work only with qualified, certified installers experienced in commercial systems.

2. Use High-Quality Components That Meet Industry Standards

Critical Components:

• Panels, inverters, mounting structures, cabling, and connectors.

• Must meet IEC/ISO certifications and local standards for durability and efficiency.

• Impact: Higher quality components reduce failure rates, improve efficiency, and lower long-term maintenance costs.

3. Establish a Routine Inspection and Maintenance Schedule

What to Include:

• Visual inspections for wear, corrosion, and cable integrity.

• Panel cleaning to remove dust, bird droppings, or pollution buildup — especially important in dry, dusty regions of South Africa.

• Frequency: At least twice annually, with more frequent cleaning as dictated by location.

 4. Prioritize Preventative Maintenance and Early Troubleshooting

Common Issues:

• Inverter faults, string underperformance, loose connections, or PID effects.

Approach:

• Use monitoring systems to detect performance drops early.

• Schedule proactive service interventions before faults cause outages.

5. Work with Professional O&M Providers

Why It Matters:

• Commercial systems often require specialized tools, certifications, and safety procedures.

What to Look For:

• Providers with proven commercial portfolios, access to OEM support, and real-time performance monitoring capabilities.

 6. Address South Africa’s Environmental Realities

Challenges:

• High temperatures can affect inverter and battery efficiency.

• Dust and wind in regions like the Karoo or Highveld require more frequent panel cleaning.

Mitigation:

• Consider inverter derating, use of liquid-cooled energy storage, and appropriate mounting angles for dust runoff.

 7. Regulatory Compliance and Documentation

• COC: Mandatory for system commissioning and grid interconnection.

Recordkeeping:

• Keep detailed logs of inspections, cleaning, repairs, and software updates to comply with insurance and audit requirements.
