THE REC ALPHA SERIES:Empowering the Energy Revolution with Ground-breaking Technology
Public
Neil Edwards – Senior Technical Communications Manager, REC SolarSeptember 08, 2020
• Next generation cell technology• Hybrid, bifacial, half-cut heterojunction cells• Leading temperature coefficient: -0.26%/ºC
• Advanced cell connections• Low temperature process using foil and wires• Solder-free cell connections• 81% reduction in panel lead content
• Super-strong frame design• Withstands exceptionally high snow & wind loads• Flexible clamping zones
• Industry-leading warranty• 92% guaranteed after 25 years• Up to 25 years product & labor coverage
The REC Alpha Series: What makes it so different?
2
Best passivation• Leading temperature coefficient• More power when sun is strongest• More energy in hot climates
REC Alpha Series: A powerful hybrid combination of cell technology
3
Better for the environment• Lead-free silver paste• No bus bars for more cell exposure
Highest bifaciality• Captures more light• Higher power
N-type technology• Highest crystalline cell structure efficiency• No LID
High power structure through technology hybrid
N-type mono crystalline silicon wafer for:• Performance• Reliability• Abundance
Amorphous silicon for: • Great absorption• Superior passivation• Low temperature deposition
Advanced Cell Connections:Environmentally-friendly, solder-free cells for high efficiency
4
Solder-free connections• Lead-free as no solder is used on cell• Lead-free silver paste• High resistance against micro-cracks
Low temperature manufacturing• Greatly reduces thermal stress for fewer defects• Energy-efficient process for fewer emissions and lower CO2 footprint
No busbars• Exposes more cell area for more absorption• Increased contact between fingers and
metallization for higher power
16 wires• Shorter current path• More contacts reduce resistance• Only 390 solder points in entire panel• Round shape to improve internal
reflection and reduce shading
Fewer production steps than competitive processes• Less complex and intensive production• No reduction in carrier collection efficiency
Super-strong frame design adds real performance advantages
5
Support bars for better protection• Limit deflection of laminate under load, protecting cells from damage
• Fewer defects means higher output and a longer life
• Increase installation flexibility through wider clamping zones and higher loads
Thinner frame• Ensures stability and durability of panel construction• Lighter weight makes panel easier to handle • Optimizes transport for fewer trucks on the road
Support only around edge of panel• Weight of load pushes laminate downwards• Increased deformation increases risk of cell breakage
and panel deformation• Needs specific and narrow clamping zones
Higher frame height• Needed to ensure stability of panel• Uses more raw materials • More transport needed to deliver same power
REC Alpha Series: Leading performance on a 60-cell platform from Solar’s Most Trusted!
6
REC’s Twin Design concept with super-strong frame design for years of durable high power
Outstanding power maximizes energy generation from limited spaces
High power density of high-efficiency HJT cells help maximize power on a rooftop space
Reduced lead content due to advanced, solder-free cell connections
Leading temperature coefficient for more energy in the heat of peak times
Warranted power after 25 years for a secure investment
