Install flashing at each mounting point to prevent water infiltration, carefully lifting shingles and securing flashings with appropriate fasteners.
Attach the L-feet or mounting brackets to the roof attachments, ensuring proper torque specifications are met. Use a calibrated torque wrench to prevent over-tightening, which could compromise the mounting system’s integrity. Install the rails perpendicular to the rafters, maintaining level alignment using a laser level or string line.
Secure rail splices at connection points, ensuring proper expansion gaps for thermal movement. Install end clamps and mid clamps at specified intervals, confirming they align with the solar panel mounting zones. Check all connections for proper torque values and structural integrity.
Add any required grounding equipment according to local electrical codes. Install wire management solutions, such as cable clips or raceways, beneath the rails to organize and protect electrical connections. Verify that all components are properly aligned and secured before proceeding with panel installation.
Document all torque values and mounting locations for quality control purposes. Perform a final inspection of the mounting system, checking for proper spacing, alignment, and structural integrity before proceeding to the next phase of installation.
Panel Placement and Securing
Proper panel placement is crucial for maximizing solar energy generation and ensuring system longevity. After selecting quality solar panels, precise positioning becomes the next critical step. Begin by marking mounting points according to your installation plan, ensuring they align with the roof’s structural support beams. Use chalk lines to create accurate grid patterns that will guide panel placement.
Secure mounting rails with appropriate fasteners, maintaining proper torque specifications to prevent future loosening. When positioning panels, maintain consistent spacing between units to allow for thermal expansion and facilitate airflow. Standard gap measurements typically range from 1-2 cm between panels, though specific requirements may vary by manufacturer.
Install panels sequentially, starting from the bottom row and working upward. This approach provides a stable platform for subsequent installations and helps maintain proper alignment throughout the array. Secure each panel using the manufacturer-recommended mounting clamps – typically a combination of mid and end clamps. Pay special attention to edge panels, which may require additional securing methods to withstand higher wind loads.
Verify that all panels are level using a digital inclinometer, and double-check that mounting hardware is properly tightened to specified torque values. Document all installation measurements and mounting points for future reference and maintenance purposes.
Electrical Connections
Proper electrical connections are critical for the safety and efficiency of photovoltaic systems. Begin by identifying the positive and negative terminals on both the solar panels and the charge controller. Use appropriately sized cables based on the system’s voltage and current requirements, ensuring they meet local electrical codes and standards.
When stripping cables, remove precisely the right amount of insulation to prevent exposed conductors while maintaining solid contact. Utilize proper crimping tools for terminal connections, applying the correct pressure to create secure, low-resistance joints. For MC4 connectors commonly used in solar installations, ensure they click firmly into place and verify the connection is weathertight.
Series connections require linking the positive terminal of one panel to the negative terminal of the next, while parallel connections join all positive terminals together and all negative terminals together. Double-check polarity before making final connections to prevent potential system damage.
Install junction boxes in accessible locations, using appropriate cable glands to maintain environmental protection. Apply anti-oxidation compound to exposed copper connections to prevent corrosion. Secure all cables with UV-resistant zip ties or cable clips, maintaining proper bend radius and avoiding sharp edges.
