REC Solar's Alpha REC435AA 72 solar panel is a revolutionary solar panel achieving incredible levels of efficiency, power, and strength. This reliable solar panel is ideal for homes or businesses requiring a very efficient, cost-effective solar panel that provides reliable power output.

REC Alpha Series Features

REC Alpha solar panel black frame
Aluminum Anodized Frame
  • The world’s highest power 72 cel solar panel.
  • Greater amount of sunlight converted to electricity.
  • A beautiful solar panel with reinforced frame.
  • Over 20% more power from the same install.
  • All backed up by an industry-leading warranty.
  • This is the REC Alpha Series.

HJT Monocrystalline & Thin Film Technologies

Emerging from REC’s leadership in half-cut cell technology, the Alpha is built around 144 half-cut heterojunction cells (HJT) and advanced connection technology, designed by engineering experts from Germany and Singapore. With HJT, REC combines the benefits of N-Type monocrystalline silicon solar cells with those of thin film technologies for much higher efficiency and energy yield, even at higher temperatures.

REC Alpha REC435AA 72 Benefits

  • REC’s pioneering and award-winning ‘Twin Panel’ design: Introduced in 2014, this delivers demonstrably better performance in shaded conditions.
  • REC’s commercialized half-cut cell technology: The Alpha features high efficiency n-type mono wafers between thin layers of amorphous silicon.
  • REC’s unique frame design: The 30 mm thin frame construction allows more panels per pallet, an easy installation and allows the Alpha to withstand snow loads of 7000Pa.
  • Industry-leading warranty: 25-year product warranty on installations by REC Solar Professionals (otherwise 20 years), and a 25-year power output warranty.
  • Even better for the environment: Manufacturing of REC Alpha solar panels requires less energy, which is further reducing the carbon footprint.

REC is known for leading standards of design and manufacturing to produce long-lasting and high-performance solar panels with reliable power output.


REC Alpha Solar Panel Warranty

The REC435AA 72 is guaranteed high power output over its warranted lifetime. The REC Alpha series comes with REC’s best warranty:


Subject to the terms and conditions of this Limited Warranty, REC warrants that the actual power output of the product will reach at least 98% of the nameplate power output specified on the product during the first year (calculated from the date of production as identified on the product). from the second year, the actual power output will decline annually by no more than 0.25% for a period of 24 years, so that by the end of the 25th year, an actual output of at least 92% of the nameplate power output specified on the product will be achieved.


Subject to the terms and conditions of the Limited Warranty, for a period of 20 years from the date of purchase by the Original
End-User (not exceeding a maximum period of 20.5 years from the date of production as identified on the Product), REC warrants that the Products:

  • Are free from defects in material and workmanship if installed and used in accordance with the installation instructions
  • Will remain safe and operational if cable and connector plugs are installed professionally and are not permanently positioned in water; provided however, that damage to the cable caused by abrasion on a rough surface due to insufficient fixing or to unprotected running of the cable over sharp edges is excluded. Damage caused by animals is also excluded
  • Will not experience freezing up of the aluminum frames if installed correctly.

REC TwinPeak 2 Mono REC315TP2M 315W Solar Panel Review

TwinPeak 2 Mono Technology

REC TwinPeak 2 Mono Series solar modules use unique and innovative technologies, and a ground-breaking layout, to give you a high efficiency and high power output product. Based on 120 laser cut monocrystalline PERC cells, the REC TwinPeak 2 Mono Series includes five different technologies which together, result in an extra power output of over 24 Watts per square meter.

REC TP2M Mono Solar Panel Review

· Half-cut cells: +5 watts
Laser cut polycrystalline cells reduce internal resistance for higher power output, higher efficiency and increased reliability.

· Monocrystalline cell structure: +12 watts
The latest monocrystalline technology provides more light absorption than previous polycrystalline technologies.

· Passivated Emitter Rear Cell (PERC): +4 watts
New generation of cell technology captures more wavelengths of light through mirror-like architecture for higher efficiency.

· 4 Bus Bar: +2 watts
A shorter distance for electrons to travel vastly improves the current flow, reducing resistance in the cell and increasing efficiency.

· Split Junction Box: +1 watt
The three three cell technologies combine in the innovative junction boxes for a higher energy yield, while reducing heat and increasing reliability.

     = 24 watts more power per square meter

PERC Technology

PERC passivated emitter rear cell


Passivated Emitter Rear Cell (PERC) technology increases solar cell efficiency through the dielectric layer that reflects back into the cell any light that has passed through to the rear without generating electrons. Through this reflection, the photons are essentially given a second chance to generate current, making more power.


Quality to count on for years to come

The REC315TP2M 315W solar panel features a weatherproof anodized frame designed to keep its appeal for many years to come. This special 120 PERC solar cell PV module is easy to install with made-to-fit cables and multiple grounding points that reduce the ground wire needed in installation.

Combined with industry-leading product quality and the reliability of a strong and established European brand, REC Twin Peak 2 Mono solar panels are ideal for roof-mounted commercial utility grid-tie solar power systems. These modules combine long lasting product quality with reliable power output. REC combines high quality design and manufacturing standards to produce high-performance solar modules with uncompromising quality.
