Summary

Introduction to REC Solar Panel Installation

Installer Responsibilities and Duties

Installers must ensure safe, effective installation, adhere to local standards, and follow all system component instructions.

Safety Measures for Solar Panel Installation

Electrical Shock Hazard Warnings

Solar panels generate DC; DC arcs are lethal. Isolate system, follow inverter instructions, discharge high-voltage components.

Work Area Safety Precautions

Follow local regulations for working at heights and fall protection. Ensure working surfaces are structurally sound.

Specific DC Electricity Hazards

DC voltage can be dangerous. Observe safe handling to avoid sparking, fire hazards, burns, and electric shocks.

Electrical and Mechanical Installation Requirements

Electrical Installation Safety Warnings

Safety is paramount. Follow electrical requirements to avoid risks of sparking, fire, burns, and lethal electric shocks.

Fire Safety Guidelines for Panels

Panels are Class C/Type 2 fire classification. Check local authorities for fire safety requirements and setbacks.

Panel Installation Procedures

Securing Panels to Mounting Structures

Installations must comply with IEC 61215/61730 test loads. Site-specific factors like wind/snow must be considered.

Clamp Specifications and Torque Settings

Secure modules with torque (12-25 Nm). Ensure clamp grip length is within clamping zones. Avoid excessive pressure.

REC Alpha Pure Series: Continuous Rail Mounting (Short Side)

Clamp Specifications and Zones (Short Side)

Details clamping zones, clearance gaps, and test loads for continuous rails parallel to the short side of REC Alpha Pure Series panels.

REC Alpha Pure Series: Continuous Rail Mounting (Long Side)

Clamp Specifications and Zones (Long Side)

Details clamping zones, clearance gaps, and test loads for continuous rails parallel to the long side of REC Alpha Pure Series panels.

REC Alpha Pure Series: Short Rail Mounting

Clamp Specifications and Zones (Short Rails)

Details clamping zones, clearance gaps, and test loads for short rails with REC Alpha Pure Series panels.

Caution on Clamping Zone Load Ratings

Center point and grip length must be in the same clamping zones. If zones differ, lowest load value applies.

REC Alpha Pure-R Series: Continuous Rail Mounting (Short Side)

Clamp Specifications and Zones (Pure-R Short Side)

Details clamping zones, clearance gaps, and test loads for continuous rails parallel to the short side of REC Alpha Pure-R Series panels.

REC Alpha Pure-R Series: Continuous Rail Mounting (Long Side)

Clamp Specifications and Zones (Pure-R Long Side)

Details clamping zones, clearance gaps, and test loads for continuous rails parallel to the long side of REC Alpha Pure-R Series panels.

REC Alpha Pure-R Series: Short Rail Mounting

Clamp Specifications and Zones (Pure-R Short Rails)

Details clamping zones, clearance gaps, and test loads for short rails with REC Alpha Pure-R Series panels.

Caution on Clamping Zone Load Ratings for Pure-R

Center point and grip length must be in the same clamping zones. If zones differ, lowest load value applies.

Alternative Mounting Methods

Mounting Panels Using Frame Holes

Panels can be installed using four mounting holes with suitable devices. Comply with IEC 61215/61730 requirements.

Caution Against Frame Modification

Product warranty void if additional holes are made in the frame. Use corrosion-resistant materials.

Installation Procedures for Mounting Holes

Support panel frame with two rails. Use corrosion-resistant materials, all four holes, washers, and electrical bonding.

Six-Point Mounting Configurations

REC Alpha Pure Series Six-Point Mounting

Secures the panel on three continuous rails with three clamps on each side in marked zones.

Caution for Six-Point Mounting

Middle rail must not be on junction box side. Use three continuous rails. Clamp center/grip must be within marked zones.

Six-Point Mounting for REC Alpha Pure-R Series

REC Alpha Pure-R Series Six-Point Mounting

Secures the panel on three continuous rails with three clamps on each side in marked zones for Pure-R series.

Caution for Pure-R Six-Point Mounting

Middle rail must not be on junction box side. Use three continuous rails. Clamp center/grip must be within marked zones.

Panel Drainage and Grounding

Grounding Installation Procedures

Use suitable clips/lugs, attach to grounding holes, follow manufacturer instructions for safe connection.

Connections, Connectors, and Cable Management

Connector and Cable Requirements

Connectors must be secure, tight, electrical/mechanically sound. Use UV-resistant cables/connectors.

Electrical Shock Hazard During Connection

Work safely with electrical connectors. Do not work on live parts. Disconnect from grid before maintenance.

Panel Maintenance and Recycling

REC Alpha Pure Series Panel Characteristics

Maximum Ratings for Alpha Pure Series

Outlines maximum operational temperature, system voltage, test loads, fuse rating, and reverse current.

Annex 1: Water Platform Installations

Safety Procedures for Water Platforms

Immediately disconnect system if deviations occur. Disconnect DC at inverter if platform submerges. Do not salvage panels in sunlight.

Annex 2: Installations with Module Level Power Electronics

Caution on MLPE Installation Practices

Maintain 2.5mm gap between MLPE and backsheet for thermal expansion. Do not use mounting holes or drill extra holes.
