Anyone can build a solar panel that works here on Earth, now strap that same solar panel to a rocket that subjects it to 8 Gs of bone jarring thrust and then expose it to high energy cosmic rays as well as temperatures that can soar as high as 300oC and now you have engineered a solar panel.

That's exactly the type of expertise that has been perfected by Mitsubishi Electric engineers that began when they established their space satellite business more than 40 years ago. Building on that experience and utilizing the latest state of the art patented process for manufacturing multi-crystalline silicon, Mitsubishi Electric has achieved real world efficiencies, tolerance levels and reliability that was once thought to be impossible.

And unlike other manufacturers they did it without using toxic lead solder in their panels. Since 1974 Mitsubishi Electric is one of the oldest and most trusted names in the industry. Because Mitsubishi Electric cares about the environment they use absolutely no toxic lead solder in the manufacture of their solar panels.

Instead they use silver electrodes which not only protects our precious environment but also enhances efficiency which is why Mitsubishi solar panels outperforms many of their competitors and gives you a bigger rebate at a better price per watt. A typical conventional 3 kW solar array uses up to 864,000 milligrams of lead. A Mitsubishi 3 kW array uses Zero lead solder. These U.S. Mitsubishi solar panels offer far better performance than any brand of solar roof tiles.
