How Solar Panel Installation Works

Setting Up Scaffolding

Scaffolding is the first step in the physical installation process. It ensures safety for you and the installation team while working on elevated surfaces. You’ll need to set up scaffolding around the roof area where the solar panels will be installed. This structure provides stable access to the roof and prevents accidental falls.

Safety protocols are critical during this stage. Make sure the scaffolding is securely anchored to the ground and positioned to allow easy movement. If you’re hiring professionals, they will follow industry standards to ensure the scaffolding meets safety requirements.

Tip: Always inspect the scaffolding for stability before starting any work. Loose or improperly assembled scaffolding can lead to accidents.

Installing the Mounting System

The mounting system is the backbone of your solar panel setup. It secures the panels to your roof and positions them for optimal sunlight exposure. You’ll need to choose a mounting system based on your roof type—flat, sloped, or metal—and the weight of the panels.

Most systems are customized to achieve a 30-degree tilt angle facing south or southwest. This angle maximizes energy production by capturing the most sunlight throughout the day. Roof attachments, module clamps, and mounting rails are key components of the system. Roof attachments are fastened directly to the roof and surrounded by flashing to prevent leaks. Module clamps hold the panels securely, while mounting rails connect the panels to the roof attachments.

Mounting systems typically account for about 10% of the total cost of a solar system. For example, a $10,000 solar system would allocate approximately $1,000 to the racking system. Costs vary depending on the type of racking, equipment, and labor required.

Placing and Securing Solar Panels

Once the mounting system is installed, it’s time to place and secure the solar panels. Position the panels to maximize sunlight exposure while avoiding obstructions like trees or buildings. Tools like solar pathfinders and shadow analysis can help you determine the best placement.

Panels are secured using heavy-duty clamps that hold them firmly to the mounting rails. Installation teams follow strict quality control protocols, including pre-installation roof assessments and final system inspections. These steps ensure the panels are securely attached and aligned for optimal performance.

Testing is an essential part of this stage. Voltage testing, current measurement, and solar irradiance measurement validate the system’s performance under different weather conditions. For example:

Note: Severe weather conditions can impact solar panel systems. Use FEMA’s National Risk Index to identify weather risks at your site and implement design strategies to enhance resilience.

By following these steps, you’ll ensure your solar panels are securely installed and ready to generate clean energy for years to come.

Wiring the System

Wiring the solar panel system connects all components to ensure efficient energy flow. Begin by linking the solar panels to the inverter using properly sized cables. These cables carry the direct current (DC) generated by the panels. Use high-quality materials to minimize power loss and overheating. Secure the cables with conduit materials that comply with electrical safety standards. This step protects the wiring from environmental damage and ensures long-term reliability.
