REC TwinPeak REC340TP2S 72 340W Solar Panel

REC Solar's TwinPeak REC340TP2S 72 solar panels are premium solar modules with superior performance at a low price. The REC TwinPeak 2S 72 takes the power output of 72-cell polycrystalline panels to groundbreaking new heights with it's twin panel design. This reliable solar panel is ideal for commercial PV installations requiring a very efficient, cost-effective solar panel with reliable power output.

TwinPeak 2S 72 silver frame

REC TwinPeak 2S 72 Series solar panels feature an innovative design using 144 laser cut polysilicon HC solar cells. This results in higher panel efficiency which can provide over 12 watts more power output per panel than traditional polycrystalline technologies. This means optimum use of valuable roof space and reduced balance of system costs.

For commercial PV power plants of all types and sizes, REC TwinPeak solar panels have an innovative design with high panel efficiency and power output. This means that you can enjoy maximum power in the space available. In parallel, REC TwinPeak panels can deliver a system with the required power using fewer panels.

REC TwinPeak 2S REC340TP2S 72 Benefits

  • High CEC PTC Rating
  • More power for more electricity generation
  • Higher yield through improved performance in shaded conditions
  • Breakthrough technologies for increased light capture
  • 100% free of Potential Induced Degradation (PID) efficiency losses
  • Certified for Salt Mist & Ammonia Corrosion Resistance

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

REC TwinPeak 2S 72 Shade Tolerance

REC TwinPeak 2S 72 Solar Panels Are More Shade Tolerant

Solar panels with REC TwinPeak 2S technologies have a unique “twin” design, which enables them to generate electricity even when they are partially shaded. Over time, you get a higher yield from your installation.

If any part of a standard 72-cell solar panel is shaded, it will lose at least one string, i.e., 1/3, of its power production and even stop generating electricity fully if shaded across the module width as illustrated to the right.

REC TwinPeak REC340TP2S 72 340 Watt Solar Panel Review

TwinPeak 2 Technology

REC TwinPeak 2S 72 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 polysilicon cells, the REC TwinPeak 2 Series includes four different technologies which together, result in an extra power output of over 12 Watts per module.

REC Twin Peak 2S 72 Solar Panel Review

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

· 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.

     = 12 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 REC340TP2S 72 solar panels feature a weatherproof anodized frame designed to keep its appeal for many years to come. These special 120 HC solar cell PV modules are 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 2S 72 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.
