What You Should Know About Mitsubishi Solar Panels
Mitsubishi solar panels are made by the good folks at Mitsubishi Electric.
Mitsubishi has been developing photovoltaic technology since 1974 and have recently developed a solar cell with the world's highest conversion efficiency rate of 18.6%
How did Mitsubishi make their solar panels so darn efficient?
Well, for one thing they developed “solder-coatingless cells”. Hopefully the Mitsubishi marketing department will work on a sexier name, but a "solder-coatingless cell" just means a cell that requires no solder coating.
This removes lead from the process (good environmentally), and also allows expanded light reflection (improved efficiency).
Mitsubishi has also:
Developed "fine-grid electrodes" (expanding light-receiving area)
Improved their "back surface field" structure
Used anti-reflective coating so less sunlight is reflected from the module
Used a unique bus bar design (reducing resistance)
Developed a high reflectance back film (increasing reflection power from 80%* to 90%)
Used cerium-free, high transmittance glass
Mitsubishi solar panels also have some features designed to improve reliability such as:
Straight tabs (reducing stress on tab wiring)
Increased distance between bus bar and module frame (so your power isn't reduced when dust builds up on the module corners)
Anodized aluminium frames with clear coating (corrosion-resistant)
Yes, Mitsubishi is producing a sturdy and efficient solar panel.
Here are the specs on their different models:

Now, onto the stats...
Rated Power at STC (Standard Test Conditions) This will be the "advertised" wattage of the panel you're looking at (e.g. 180 watt or 205 watt).
