Solar Power - Product Features


Highly Reliable

Photovoltaic modules are high-tech products engineered for extended use in environments with extreme
temperatures and harsh weather conditions. Mitsubishi Electric’s many years of experience and know-how
are behind the introduction of design and structural improvements that lead to PV modules with long-term
reliability. Our goal is nothing less than the supply of malfunction-free products.

Original Derating Design Concept

Mitsubishi Electric’s original derating design concept reduces the electrical
stress of each electrical component by the rated value for actual use time, lowering the
product failure rate and ensuring reliability in the long term.


Straight Tabs

Expansion of solar cell string pitch and adoption of newly developed straight
tabs combine to eliminate stress on the tab wiring, ensuring dependability over the long term.

Traditional Module


Newly Developed Module


Double-sided Independent Tabs

Mitsubishi Electric solar cells have separate connecting tab wiring between the front and back sides.
This is an effective step toward optimization of connecting conditions, while curving cell warp to
support the move toward thinner solar cells.


Reliable Bus Bar

Adoption of a structure that ensures ample distance between the bus bar and module frame helps prevent
short circuits, insulation deterioration and other problems. It likewise curbs declines in power output
caused by dust accumulated in the lower part of modules.


Lower Slope of Module Frame

Mitsubishi Electric module frames have been designed with a lower slope of 30% compared
to traditional models. This innovation can provide a larger generation of power in cases
where the modules are installed at lower angles, by preventing dust from accumulating in
the frame area.


TD Series: Protection Bar

Mitsubishi Electric has developed a unique “Protection Bar” back side module. The combination of
high-strength glass and Protection Bar can pass the static load test 5400 Pa of IEC61215 2nd
edition. The Protection Bar also easily meets the requirements of 545 grams (1.18 pound) steel
ball drop-testing from a height of 1.295 meters (51 inches).


Higher Tensile Strength Structure

A newly developed frame dramatically improves snow load resistance by enhancing
tensile strength between the laminate and module frame.


Better Water Drainage Structure

In order to improve water drainage, we added holes on the edge of the frame back.
Thanks to this improvement, the potentiality of moss or dirt accumulation and damage
by water is considerably mitigated.


High-corrosion Resistance of Frame

The module frame features anodized aluminium with clear coating -- two pivotal steps toward
high-corrosion resistance and reliable use even under truly severe environmental conditions.


Hollow-less Structure Frame

The frame is engineered with optimum thickness and structure, for improved bending strength.


TD, TE Series: Four-Layer Structure Back Film

The newly developed PET type back film offers four-layer construction. This design greatly achieves
maximum system voltage of 1000V, further improving the environmental characteristics of the module.
