REC Solar Panel Performance Exceeds Expectations
When it comes to solar panels, real world conditions are often very different
those experienced under a standard testing scenario. The manufacturer of REC
solar modules says customers using their products are continually yielding higher than expected electricity volumes.
Because solar panel performance varies so much in different locations,
environments, weather conditions and even the time of day, manufacturers need a
way to assign wattage class; also known as nameplate wattage. The way this
figure is arrived at is most often attained under Standard Test Conditions (STC).
STC consists of a solar irradiance of 1,000 W/m², solar spectrum of AM 1.5 and
cell temperature of 25°C.
While solar panel brands X, Y and Z may attain near identical performance under
standard test conditions and consequently bear the same nameplate wattage, once
they are being used in the real world; performance between different brands can
REC reports its award-winning Peak Energy Series solar panels are often
exceeding customer expectations and has started formally documenting reports
from customers using their modules.
one of its own installations at REC’s integrated manufacturing facility in Singapore
shows a delivered yield of 5% above that simulated in PVsyst, a solar prediction
software application. Singapore is well known for its hot and humid conditions -
is the enemy of solar panels
as it negatively impacts on performance.
The poorer the quality of a module, the bigger the impact it will usually have
on electricity output above cell temperatures of 25°C; a scenario that commonly
occurs in countries such as Australia.
While 5% may not sound like a great deal, over the life of a solar panel it
represents a substantial amount of electricity in a home
scenario and particularly in commercial
installations. The array in question was installed in January 2010
and since that time REC has further enhanced its technology.
Earlier this year, REC solar panels were announced the best
performing panel of 2011
; the result of ongoing independent field testing in
real-world conditions of 45 solar module brands.
More recently, REC announced enhancements to its Peak Energy
, improving yields by up to nearly 6%.
"System designers are increasingly selecting photovoltaic modules based upon yield rather than nameplate watt class. Superior design and manufacturing are at the core of
REC's high-yield performance and reliability," says the company.
Introduced to the home solar power market in Australia in 2010 by Energy
have since become the panel of choice in many local residential
solar panel installations.
