REC Boosts Peak Energy Solar Panel Performance
REC has announced enhancements to its award-winning Peak Energy series solar
panels, improving yields by up to nearly 6%.
REC says the temperature co-efficient of Pmpp has dropped from -0.43%/°C to -0.40%/°C.
This indicates the percentage power lost for each 1° increase in temperature.
While the benefit will vary on local ambient temperature, at an average ambient temperature of 30°C, the simulated yield will be 0.9% higher than with previous data due to this factor alone.
Additionally, a reduction in operating temperature from 47.9°C to 45.7°C will
help to increase expected yield. REC says the new NOCT (Nominal Operating Cell Temperature)
and temperature co-efficient numbers could see Peak Energy modules surge to near the top of the PTC:STC ratio.
The PTC:STC ratio is a key indicator in some countries for performance at hot temperatures.
REC states it has simulated the impact of these and other changes on expected performance using
industry leading solar prediction software PVsyst; which shows the enhanced REC
have an improved yield of 5.2 - 5.9%.
The company states for poly-silicon (polycrystalline) modules , the Peak Energy
module is now " best in class" and enables REC to compete or even beat most mono-silicon
REC solar modules are also characterised by a very low energy payback time of
around 12 months. Energy payback refers to the amount of time it takes a panel
to generate the same amount of electricity that went into its production.
Last month, REC celebrated production of the 5
millionth Peak Energy Series module
at the 13th SolarExpo; held in
After being introduced to the home solar power market in Australia in 2010 by Energy
, REC Peak Energy Series modules have increasingly been the
module of choice for many local solar panel installations.
A winner of multiple awards, ongoing field testing by Photon Laboratory of 45
solar module brands found REC solar panels to be the best
