The time of par value photovoltaics
Large size photovoltaic products
Gradually becoming the focus of users
In the view of some people
Who don't know the facts
The larger the module size
Its value gain must also be growing
But is that true?
On the premise of reliability and safety
Increasing the size of components reasonably
Can effectively improve product power, and reduce photovoltaic cost
At the same time, we need to recognize a cognitive misunderstanding - -
An ultra-high-value photovoltaic module, not the bigger the better
What market terminals need
has always been a ' double excellent ' product with both quality and value
*When the income growth is nearly zero,
the risk coefficient will rise sharply by blindly increasing the module size.
What kind of module size
is the optimal choice of power station ?
And,what harm will too large module size bring to users ?
Photovoltaic modules are shipped around the world mainly through containers.
Horizontal vertical packing
is a mature and reliable packing method in industry.
Standard module dimensions,
are based on international container dimensions.
Taking into account the hidden crack, damage and other risks in transportation,
the boundary conditions are calculated.
①Too large size will cause quality risks
such as hidden crack and breakage of components during transportation.
②If transverse / vertical packing,
It will cause space waste or lodging risk after disassembly.
According to the best ergonomics design
The best width of the component
is the distance from the natural expansion of both hands to the comfort
of both sides of the component
①Module size design needs to consider whether the handling is easy and convenient, safe and reliable.
②Excessive size can lead to the risk of dumping due to the instability of hand grip center of gravity during handling.
Module size affected by many factors,
Excessive size will cause risks such as hot spots of modules.
will also bring challenges and risks to the load capacity of the module support.
At the same time,
the module surface resistance is also reduced.
The size is too large,
the modules in the sand and other external force,
glass is more fragile.
In extreme weather conditions,
its long-term reliability also needs time verification.
