Are two sides better than
one?
What's better than a single sided
solar panel? Why a double sided solar panel of
course. You might be asking yourself, so how on
Earth do you smultaneously illuminate both sides of
a double sided solar panel? The answer.....reflected
light.
With exception to surfaces that are
pitch black in color, nearly all surfaces reflect
some degree of light and double sided solar panels,
otherwise known as Bifacial solar panels, take
advantage of this principle. The double sided
increase in power production is especially
noticeable in ground mount installations where a
light colored material such as white rock or sand
has been placed below the ground mounted array.
Amazingly, Bifacial solar panels can continue to
produce some power
even when the front side of
these panels are completely covered in snow.
Another adavantage over traditional single sided
solar panels is that this technology uses specially
designed cells that use higher performance N-type
technology whereas most traditional single sided
cells use lower efficiency P-type technology.
N-type silicon cells not only offer the
potential for higher efficiency but also provide for
reduce light induced degradation than is typically
seen in P-type solar cells.
Here's an excellent article that explains the
advantages of N-type solar cells versus P-type cells
Here's a list of a few more reasons why your
next solar system should include Bifacial, double
sided solar panels.
1. The Bifacial N-type solar panels that are
used in Bifacial solar systems offer a much higher
PTC to STC performance ratio than competing
technologies. For example, The new 300 Watt, 60 cell
solar panels that are used in Bifacial solar
systems offers a better 94.3% PTC to STC ratio
rating for better "Real World" performance according
to the California Energy Commission's performance
rating listings than over 119 of SunPower's solar
panel models.

2. Bifacial N-type solar panels
offer a heat resistant -0.28%/degree C temperature
coefficient for better performance in warm/hot
climates.
3. Bifacial N-type solar panels offer a minus 60
degree C extreme cold temperature rating.
4.
Bifacial N-type solar panels are less than 1/4 inch
thin and are made with a stronger, see through,
glass on glass, frameless contruction that offer far
better aesthetics than aluminum framed, plastic
backed solar panels.
5. Bifacial N-type solar panels offer efficiency
ratings of up to 22.6%
6. Glass on glass
design does not require any module grounding.
7. Frameless design makes these solar panels
ideal for harsh environments such as installation
near bodies of salt water.
With a faster
return on investment due to Bifacial technology's
lower cost when compared to competing technologies
and it's higher energy yield, the time is right to
consider Bifacial solar technology in you
residential or commercial project.
