Modern solar modules are characterized by wafer-thin, brittle cells. These cells have a maximum thickness of 170 micrometers, which is two to three times thinner than regular A4 paper 1. So, to ensure that a solar energy system operates safely and effectively, handling and storage solar equipment properly is necessary. When working with solar panels, inverters, mounting structures, and related components, installers should adhere to the following safety instructions. During the solar panel installation process, there are a few bad habits that might cause performance decreases. To maximize the power potential of solar panels we are going to share brief guidelines on handling and storage of solar equipment to help the solar installer.
Handling Solar Panels
The majority of installed solar panels traveled hundreds of kilometers to go from manufacturer to rooftop. A panel’s performance can change in the final several dozen meters of its trip. Managing solar panels is not an easy task. Approximately 18–20 kg is a substantial weight 2. It’s not just challenging labor, but also risky when you take into accounts the difficulties of raising modules onto a roof and a little wind. You should always,
- Avoid rough handling: Because solar panels are composed of tempered glass, impacts can damage them. Take caution while handling panels to prevent breaking or fractures.
- Use lifting equipment: Use suitable lifting equipment, such as panel lifters or suction cups, when shifting big panels to avoid strain or damage.
- Avoid walking on panels: Walking onto solar panels can cause them to crack and become less efficient. When installing panels, use defined routes or walkways to get access to the panels.
Inverter Handling
One of the most important elements of a solar energy system is an inverter. It’s a device that changes the electricity produced by a solar panel, known as direct current (DC), into alternating 120V/240V current (AC), which is used by the electrical grid 3. Like solar panels, inverter systems need to be handled carefully for maximum efficiency, long lifespan and safety installation.
- Turn off the inverter before handling: Make sure the inverter is turned off before handling. This reduces the risk of electric shock during maintenance or installation.
- Pay attention to manufacturer guidelines: To ensure safety and maximum efficiency, follow the manufacturer’s instructions about the handling and installation of the solar inverter.
Mounting Structures and Racking Systems
Solar PV panels are installed onto structures known as solar mounting and racking systems. The primary purpose of a solar mounting and racking system is to enable solar panels to be positioned on a surface, such as a rooftop or the ground, and to maintain their position so that they get the maximum amount of sunlight all year long4. Solar PV panels are vulnerable to vibrations from the environment, such as wind, if they are not mounted and racked properly. This can lead to the panels coming loose and having unwanted effects.
- Check for structural integrity: Make sure the mounting structures and racking systems are capable of securely supporting the weight of the panels by inspecting them before installation.
- Use proper fasteners and hardware: Make sure that the mounting system’s hardware and fasteners are of the highest quality and appropriate for the surrounding environment.
Handling Electrical Components
A solar photovoltaic (PV) system is made up of several essential electrical parts that are designed to capture sunlight and transform it into electricity. Solar panels, which are made of photovoltaic cells that convert sunlight into direct current (DC), are at the center of the system. After that, inverters convert DC power into alternating current (AC), which is fit for residential usage. charging to avoid overcharging. The system may also include a charge controller for battery-based setups, regulating charging to prevent overcharging, wires and cables. Handling safely is essential in the installation process.
- Pay attention to electrical safety precautions: Make sure that always take the appropriate safety precautions while handling electrical components. Using the proper personal protective equipment (PPE) and switching off electrical sources are part of this.
- Prevent from contacting water: To avoid electrical dangers, keep electrical components dry and away from water.
Storage Guidelines
Solar equipment must be stored properly to maintain its lifespan and efficiency. Make sure the solar panels are clear of debris and take immediate care of any wear or damage before storing away any components. Make sure all parts are turned off before disconnecting panels from inverters and power sources. In order to protect against weather and possible theft, choose safe indoor storage for your solar panels and a cool, dry place for your batteries. During storage, proper battery care is important. To reduce the chance of deterioration, try to maintain batteries in a partial state of charge, ideally between 20-80% 5.
- Prevent exposure to extreme weather: Keep solar-powered equipment dry and shielded to protect it from intense heat, sunlight, and moisture.
- Properly secure panels and components: Make sure that panels and components are securely attached and shielded from any harm caused by moving or dropping.
Documentation and Labeling
Although labeling may seem like one of the least important components of a solar system, it is essential for compliance and safety. Everyone should follow these steps.
- Component labeling: Make sure every component has a clear label and documentation to help with handling during installation and maintenance.
- Keep detailed records: Record all information about the equipment, including its specs, installation dates, and any maintenance or repairs that are done.
For any solar installation project to be successful, safe handling and storage of solar equipment is necessary. Installers can ensure their safety, maintain the reliability of the machinery, and assure the long-term efficiency of the solar energy system by following these rules. It is not just a recommended practice but also an important responsibility for solar installers to prioritize safety throughout the whole installation process.
