Methodology

Site Planning & Preparation

Before installation takes place, the following pre-installation task is essential:

Identify and ensure that pertinent documents (e.g. shop/coordination drawings, Method Statement for Solar Panel) are latest and approved.

workers installing solar panels

Applicable permits shall be applied prior to the commencement of works.

Ensure obtain the necessary PTW (Permit to Work), prior to allowing to work.

Frequently training should be conducted by the site supervisor/foreman.

Daily safety briefings should be conducted.

Conduct site safety briefing prior to commencement of work.

Identify and obtain appropriate installation tools and equipment.

Determine the staffing required and assign tasks to team members.

Secure the working area and set up signs (where applicable) to alert anyone of danger in the area.
Notify appropriate personnel that work is to begin.

During the nighttime, working areas should be marked prominently with lights and there should be an arrangement to ensure uninterrupted operation of these lights throughout the darkness.

Handling of Materials

During all the transportation, please make sure there is no strenuous vibration on the module. Because it may cause cell micro crack or damage the module.

Upon receiving the materials, all must be inspected and ensured that there are no manufacturing defects and delivery damages.

The materials shall be handled with care and shall be stored in designated areas.

Manufacturer operational control procedure manual for handling installations should be followed as much as possible.

Nominated competent manpower shall be required a mandatory competent training such as electrician, etc. with approved 3rd party certifications shall be submitted and secure approval.

PV modules are made of glass and are there for at risk of fracture or cracking. Care of handling is to be a priority. Any suspected faulty modules should be set aside for return

To include strict implementation of housekeeping shall be improved during the course of the activity. Any materials stacked on the site shall neither obstruct the emergency evacuation route nor the access to this.
Rise the material inspection base on the material delivery.

Procedure

Put on the necessary PPE and slowly unpack the solar panels and hardware

The framework, solar panels, and fixings will all be mechanically raised to the installation location.

Measure and draw out the position of the framework. Always adhere to the manufacturer’s installation instructions and any site-specific drawings.

Survey the area for the exact position of the solar panel location.

Prepared railing and framework for construction.

Lift the “Y” framework, then place it on the ground.

Set the poles in place with concrete.

When the concrete has dried/firmed up, build the roofing or canopy structure on top of the “Y” frame.

Fix the framework railing to the canopy or roof.

To the electrical connection point, dig a cable trench.

Set up meters, inverters, and isolators.

Put solar panels on the railing.

All DC cables should be marked “DANGER Live DC.”

DC cables should be run from the panels’ backs to the cable trench.

According to the plans, install wires and conduits inside the trench.

Before connecting to the supply, use an electrical test meter to make sure it is dead.

All electrical parts and warning signals should be labeled.

Affix AC cables to the equipment’s terminal boxes for the isolator, meter, and inverter.

Complete all cable connections, both DC and AC.

Verify the security and integrity of all cables and connections.

All non-live testing will be done before the system is restarted.

Check the operation of the new circuit after energizing the power supply.

Clean up the work area and place all trash in the designated garbage container.

Always leave the site in a secure state.

Commission the system.

Complete any snagging work. to client satisfaction.

Carry out the final inspection.

Testing process

  • Make sure that all string is connected perfectly
  • Disconnect the string from the inverter side
  • Do the Voc test by AVO Meter to ensure that all string’s voltage is in the accepted range
  • Connect the I-V device at the end of the strings
  • Check the Voc, Isc, and the insulation of cables
  • Compare the ideal with the actual measurement
  • Check the string polarity
  • Disconnect the device cables after finishing the test

This test should accord the following:

  • VOC
  • LSC
  • String I-V curve with reference to the irradiation and the panel inclination
  • IR of cables
  • Continuity of string
  • Polarity of string

Training

All Required training for Stipulated installation activities is provided to all technical staff for ensuring quality workmanship.

Working Hours

Site operational time shall be followed as per project progress requirements, and all relevant local authority schedules of holidays are to be observed.

Working Hours (Working in direct sunlight during hot weather conditions).

Housekeeping

Working areas will be kept clean by disposing of the waste materials in the designated areas. At the end of the day’s work, the installation supervisor will ensure that the debris is disposed of during the course of the activity on regular basis.

Dust created by work e.g. drilling, of the slab, grinding, and polishing: The area must be isolated and protected by a green net and require additional PPE for the operatives.

Any materials stacked on the site shall neither obstruct the emergency evacuation route.
