Ministry of Industry Guidelines: How to Safely Purchase and Install Solar Cell Systems

For public safety, the Ministry of Industry recommends the following essential guidelines for residential solar cell systems:

1. Identify the System Type
   Select a system that matches your budget and usage requirements:
   On-Grid: Connected to the electrical grid.
   Off-Grid: Standalone system independent of the grid.
   Hybrid: Combines both on-grid and off-grid features.
   
2. Verify Equipment Standards
   2.1) Solar Panels: Check the model, power output, and TIS 61730 or IEC 61730 certification.
   2.2) On-Grid Inverter: Must be registered and approved by the relevant electricity authority.
   2.3) Off-Grid Inverter: Should carry TIS 2603 or IEC 62109 certification.
   2.4) DC Cables: Use DC-specific cables certified under TIS 62930 or IEC 62930.
   2.5) DC Connectors: Must be securely locked (cannot be pulled apart by hand) with no exposed wiring.
   
3. Professional Installation
   Hire experienced solar contractors who hold a professional “Certificate of Knowledge and Ability” (Indoor Electrician Level 1). Ensure they provide accessible after-sales service and ongoing support.
   
4. Post-Installation Maintenance
   Regularly monitor system and app performance.
   Routinely inspect the condition of breaker boxes, wiring, and equipment.
   Install a CO2 fire extinguisher (red cylinder) near the system.
   Schedule periodic maintenance checks by qualified technicians.
   
5. Emergency Protocols
   In case of fire or emergency:
   Never spray water directly on solar panels or electrical equipment.
   If safe, immediately shut down the main breaker or inverter.
   Call 199 immediately.
   Crucial: Inform emergency responders that the property has a solar system installed.
