REC Alpha Pure-R Series: Lead-free and higher power density

• including cable (approx.170 cm) and MC4 connector system
• Four string sections in the module enable maximum performance in case of shading
• State-of-the-art cell technology and halved heterojunction cells in gapless design provide more power while protecting the environment
• Lead-free* - for the sake of the environment
• All module components including the cell connections, cross-connectors and solder joints of the junction box are lead-free
• The combination of aesthetics, lead-free processing and high performance make REC Alpha Pure the first choice for rooftop systems

* ROHS compliant

Advantages Heterojunction

• No LID = no performance degradation; you get the performance you paid for
• Outstanding performance in cold and hot climates; outstanding temperature coefficient ensures high performance even at rising temperatures
• Higher performance for greater savings and faster return on investment
• High power density per square metre (watts/m²) - REC Alpha solar panels generate more energy on the same surface area and make optimal use of even small spaces
• Over 20% more power than conventional modules

Advanced cell connection technology

• Increased number of wires for improved current flow
• Innovative cell connections minimise the risk of cell damage or micro-cracks and enable long-term high performance
• Stylish design thanks to thin, barely visible wires and uniformly black-coloured cells
• The all-black version impresses with its elegant design and makes the module a must-have for the rooftop
• Solder-free cell connections
• Low CO2 footprint thanks to environmentally friendly production

20-year REC manufacturer's warranty in accordance with the manufacturer's warranty conditions
25-year REC linear performance guarantee with maximum annual performance degradation of 0.25%, guaranteeing at least 92% after 25 years.
