Ground mounted project
A ground-mounted solar project involves the installation of solar panels and associated infrastructure directly on the ground, typically on open land or designated project sites. Key components include:
Piling
Foundations are created using driven or drilled piles to securely anchor the mounting structures. These provide stability for the entire solar array.
Module Mounting Structure (MMS)
The MMS holds the solar panels in place. It is designed for durability and optimized tilt angles to maximize solar energy absorption.
Structure Assembly
The installation of MMS involves precise alignment and secure fixing of the frames to the piles, ensuring robustness and longevity.
DC Wiring
The solar panels are connected in series or parallel using DC wiring. This transmits the direct current generated by the panels to inverters for conversion.
AC Wiring
After conversion to alternating current by the inverters, AC wiring is used to connect the system to the electrical grid or designated power storage units.
Safety Measures for Ground-Mounted Solar Projects
Ensuring safety in ground-mounted solar projects is paramount to protect workers, the environment, and the system itself during installation, operation, and maintenance. Here are the key safety measures:
Site Preparation and Risk Assessment
Before commencing any work, conduct a thorough risk assessment to identify potential hazards such as uneven terrain, proximity to power lines, or unstable soil. Clear the site of debris, vegetation, and obstructions, ensuring proper drainage to prevent flooding risks.
Personal Protective Equipment (PPE)
Workers must wear appropriate PPE, including helmets, gloves, safety goggles, steel-toed boots, and high-visibility clothing. Ensure harnesses are used for tasks involving elevated work or steep slopes.
Heavy Equipment and Machinery
Operators of heavy equipment such as pile drivers and excavators must be trained and certified. Maintain equipment regularly and operate it in accordance with safety guidelines. Define exclusion zones around operating machinery to prevent accidents.
Electrical Safety
Only qualified electricians should handle electrical installations. Use insulated tools, and ensure compliance with relevant electrical codes. De-energize circuits during maintenance to avoid electric shocks or short circuits.
Fire Prevention
Install fire extinguishers on-site and train workers in their use. Use flame-retardant materials for wiring and mounting components. Monitor the site for potential fire hazards, such as dry vegetation or fuel spills.
Environmental Protection
Avoid disturbing natural habitats or water bodies. Implement erosion control measures, and responsibly dispose of waste materials
Emergency Procedures
Establish a clear emergency response plan, including evacuation routes and first aid facilities. Train staff in first aid and emergency protocols.
By adhering to these safety practices, ground-mounted solar projects can be executed efficiently, minimizing risks to personnel and ensuring the system’s long-term reliability.
