Mitsubishi Electric’s photovoltaic modules are engineered for extended use in environments with extreme temperatures and harsh weather conditions. Our panels utilize polysilicon technology and are known for their high reliability, high-efficiency, and low environmental impact. All of our modules feature a 25-year limited warranty on power output and are designed to deliver you trouble-free electricity for years to come.

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.

Example of derating

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.

Double-sided Independent Tabs

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

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

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

Protection Bar High-strength glass

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

Higher Tensile Strength Structure Strength between the laminate and module frame

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

Better Water Drainage Structure

Water Drainage Structure (traditional) 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.
