  • IEC/IEEE Standards for PV systems

4. MATERIALS AND EQUIPMENT

  • Solar Panels (type and quantity as per design)
  • Battery storage system (type, model, and number of units)
  • Mounting and racking system for both high-rise and ground installations
  • Electrical cables and connectors
  • Inverters and charge controllers
  • Tools: Drills, wrenches, screwdrivers, cutting tools, etc.
  • Personal protective equipment (PPE) including hard hats, gloves, safety goggles, and harnesses for working at heights.

5. SITE PREPARATION

  • Conduct a site survey to assess the location, including roof or ground condition, shading factors, structural integrity, and electrical load requirements.
  • Ensure all necessary permits and approvals are obtained from local authorities.
  • Clear the installation area of any debris or obstructions that could hinder installation.
  • Mark installation points for solar panels, batteries, and electrical connections.

6. INSTALLATION PROCEDURE

A. High-Rise Building Installation

  1. Roof Assessment and Safety Measures:

    • Ensure the roof is structurally capable of supporting the weight of the solar panels and battery system.
    • Install edge protection and fall arrest systems to ensure safety during installation.
    • Confirm that the installation will not obstruct access to roof exits, ventilation, or fire safety equipment.

  2. Panel Mounting:

    • Install the mounting racks on the roof structure following the manufacturer’s specifications.
    • Ensure that the mounting system is securely fixed and properly aligned.
    • Install the solar panels on the mounting structure, ensuring proper orientation and tilt as per the design (usually between 15°-40°).

  3. Electrical Wiring:

    • Route the wiring from the solar panels to the inverter(s) using appropriate electrical conduit to ensure protection from the elements.
    • Install inverters in a location with proper ventilation to prevent overheating.
    • Connect the battery storage system to the inverter according to manufacturer specifications and electrical standards.

  4. Testing and Commissioning:

    • Test each solar panel and battery to ensure proper functionality.
    • Conduct an overall system test to verify voltage, current, and grid connectivity.
    • Ensure that all electrical connections are secure and meet electrical codes.
    • Obtain necessary inspections and approvals from local authorities.

B. Ground-Mounted Installation

  1. Site Preparation:

    • Clear the ground of any debris or obstructions that could impede the installation.
    • Perform leveling and grading work as needed to ensure the mounting structure is level.
    • Install the foundations for the mounting system (e.g., concrete footings or screw piles).

  2. Panel Mounting:

    • Install the mounting system, ensuring that it is securely fixed to the foundations.
    • Install the solar panels on the racking system with appropriate spacing to ensure maximum sunlight exposure and air circulation.

  3. Electrical Wiring and Battery Installation:

    • Run electrical conduit from the solar panel array to the inverter and battery storage system.
    • Install the battery storage system in a location with proper ventilation and protection from extreme weather conditions.
    • Connect the battery system to the inverter, ensuring that the system is properly configured.

  4. Testing and Commissioning:

    • Verify the system is generating power, ensuring all connections are secure.
    • Test the battery charging and discharging functionality.
    • Perform system integration checks, including monitoring and safety features.

7. SAFETY MEASURES

  • Ensure all personnel are equipped with proper PPE, including hard hats, gloves, harnesses, and safety shoes.
  • Establish a safe work zone, especially for high-rise installations, with proper barriers to prevent falls and accidents.
  • Ensure that electrical systems are de-energized before installation and maintenance work.
  • Use lockout/tagout (LOTO) procedures during electrical work.
  • Adhere to the manufacturer's safety guidelines and all local safety regulations.

8. QUALITY CONTROL AND TESTING

  • Perform visual inspections of the mounting structure and solar panels to ensure correct installation.
  • Test each solar panel and battery unit for functionality and performance.
  • Use a solar power meter to verify the output of the solar panels.
  • Perform an earth leakage test and ensure that the electrical systems are grounded.
  • Ensure that the battery storage system is connected properly and charging as required.
  • Provide a commissioning report detailing system performance and tests conducted.

9. HANDOVER AND TRAINING

  • Upon successful installation and testing, provide training to the building maintenance personnel or system owners on the operation and maintenance of the solar and battery systems.
  • Handover the operation manuals, maintenance guidelines, and warranty documents.

10. MAINTENANCE AND SUPPORT

  • Set up a regular maintenance schedule, including cleaning of the solar panels, checking wiring connections, and testing the batteries.
  • Offer ongoing technical support and system monitoring, if required, to ensure optimal performance.

11. CONCLUSION

This method statement provides a detailed procedure for the installation of solar panels and battery systems, both for high-rise buildings and ground-mounted installations. The process emphasizes safety, quality, and compliance with electrical and structural standards to ensure the longevity and efficiency of the solar energy system.
