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 solar panels 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 (monocrystalline) panels.
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 Italy.
After being introduced to the home solar power market in Australia in 2010 by Energy Matters, 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 performing module during 2011.
