Installing rooftop solar panels is more than just mounting modules and wiring them up. It involves working at height, roof access, structural assessment, electrical safety, and compliance with local regulations. For business owners, facility managers, or developers in Malaysia seeking a reliable solar installation partner, choosing a team of certified working-at-height professionals is a critical decision that impacts safety, compliance, system performance, and long-term return on investment (ROI).
In 2025, with the updated Energy Commission of Malaysia (EC) guidelines, the Guidelines for Solar Photovoltaic Installation for Self-Consumption in Peninsular Malaysia, stakeholders are now legally required to ensure that solar PV installations for self-consumption comply with stricter standards for design, installation, testing, commissioning, and maintenance.
Below we explain why certified working-at-height professionals are essential, what risks they mitigate, and what you should ask before awarding a solar installation contract.
Regulatory Context: What 2025 Malaysia Solar Guidelines Require
- The updated 2025 SELCO guidelines apply to any solar PV installation for self-consumption in Peninsular Malaysia.
- The guidelines stipulate that only licensed or registered electrical contractors and “competent persons” may carry out the design, installation, testing, commissioning, and maintenance work.
- This regulatory framework seeks to ensure that solar installations meet safety, technical and quality standards, while preventing sub-standard installations that may jeopardize safety or performance.
By aligning with these regulations, a solar installer demonstrates both legal compliance and commitment to safety and quality.
The Hidden Risks of Rooftop Solar Installation
Rooftop solar installation is inherently hazardous. Some of the most common and serious risks include:
- Falls from height: workers climbing onto roofs, walking across slopes, near edges or fragile roof material.
- Trip hazards: uneven surfaces, cabling, rooftop equipment, roof access constraints.
- Fragile or compromised roof surfaces: materials such as corrugated sheets, old roofs or skylight areas may not support foot traffic or heavy equipment.
- Electrical hazards: improper wiring, earthing, overcurrent protection, incorrect isolation, or substandard electrical work may lead to shocks, fires, or system failures. Especially critical under 2025 Malaysian regulations.
- Maintenance & access hazards: long-term maintenance or panel cleaning requires safe, reliable roof access even after installation. Without proper access, risk remains high.
A 2025 international occupational health review specifically calls out “falls from heights (i.e., rooftop installers with limited walking space)” among the major hazards for solar installation workers.
Because of these risks, installing solar PV is not a simple handyman job. It requires planning, trained personnel, risk mitigation, and compliance.
What “Certified Working-at-Height Professionals” Bring to the Table
When you engage a solar installer that uses certified working-at-height professionals, you gain several important advantages:
- Safety-first mindset: professionals are trained to follow safety protocols, use proper PPE (harnesses, anchor points, lifelines), and handle falls, slips, and emergency scenarios responsibly.
- Compliance with standards and regulations: ensures the installation meets 2025 EC SELCO guidelines, national electrical codes, structural safety, and legally required certification processes.
- Risk planning and job-site assessment: the team performs roof structural assessments, chooses proper anchoring, designs fall protection, identifies hazards, plans rescue routes and ensures safe access and egress.
- Rigorous installation quality: certified installers take care of proper panel mounting, secure attachments, correct earthing and bonding, labeling, and documentation which reduces risk of future failure or hazards.
- Long-term maintainability and safety: installations done with safety in mind make roof maintenance, cleaning, or future upgrades safer and easier.
These aspects directly impact not only the safety of workers, but also the reliability, performance, and longevity of your solar PV system which is critical for ESG targets, ROI, and corporate liability management.
What You Should Ask Before Choosing a Solar Contractor
When evaluating proposals, ask the contractor these questions to assess their safety and compliance standards:
- What kind of working-at-height training and certification does your installation team hold? How often is training refreshed?
- What fall protection systems will be used on my roof: anchor points, lifelines, guardrails, horizontal lines, walkways, harnesses?
- How will you assess the roof’s structural capacity and ensure that anchor points are properly installed without damaging the roof?
- Will there be a documented safety plan or Safe Work Method Statement (SWMS) for installation, and does it include rescue/emergency procedures for fall incidents?
- Who will sign off the electrical installation, testing, and commissioning? Are they a competent person under the 2025 SELCO guidelines?
- Will the installation be documented and certified (including completion and test certificates) for registration with the EC and compliance reporting?
Why This Matters for Commercial, Industrial and Agricultural Solar Projects
For commercial, industrial or agricultural clients (such as factories, warehouses, farms, or large commercial buildings), rooftop solar installations often involve sizeable systems, heavier modules, complex wiring, and multiple roof access points. In these cases:
- The risk of falls, structural load issues or maintenance hazards increases.
- Regulatory compliance is more strictly enforced under the 2025 guidelines.
- The impact of a faulty installation, from worker injury, rooftop damage or system failure, is magnified in financial, operational, and reputational terms.
Using certified working-at-height professionals becomes not only a best practice, but a strategic necessity. It is a risk-mitigation decision that protects people, assets, and long-term business interests.
How i2 Energy Applies These Principles in Every Project
At i2 Energy we follow a comprehensive approach on every solar installation combining working-at-height certification, continuous safety training, rigorous roof assessment, fall protection planning, and compliance with Malaysian regulatory requirements.
Before work begins, our team:
- reviews structural and roof drawings, identifies hazards, plans safe access routes, and selects appropriate anchoring and fall protection systems.
- prepares a full safety plan, including PPE requirements, collective protection, individual fall arrest systems, procedures for roof access and rescue, and emergency protocols.
- ensures that a registered, competent electrician handles all electrical tasks, including earthing, bonding, overcurrent protection, labeling, testing and commissioning.
After installation, we ensure the system’s structural integrity and electrical safety.
With this approach, our clients receive a solar PV system that delivers reliable, long-term performance and a peace of mind knowing it was installed with top-level safety, quality, and compliance.
Conclusion
Rooftop solar installation delivers long-term sustainability, cost savings, and ESG value. But beneath every panel lies a critical foundation of safety, regulation, quality, and human responsibility. Choosing certified working-at-height professionals is not optional. It is essential. Especially under the 2025 Malaysian solar PV regulations to protect your workforce, your investment, and your reputation.
When you partner with i2 Energy, you get more than just solar panels: you get professional installation, certified safety-first teams, regulatory compliance, and a solar system built for performance and longevity.
