ZTE debuts solar-powered phone
The Coral-200-Solar gets its power from above.
(Credit: ZTE)Samsung wasn't the only company showing a solar-powered cell phone at the GSMA World Congress. On Wednesday, Chinese manufacturer ZTE launched a green model of its own.
Created with Digicel and Intivation, the Coral-200-Solar is designed for emerging markets where electricity may not be readily available. And, of course, it's Earth-friendly.
Exact feature details are sketchy at this point, but from what we can tell, the phone won't offer a lot of goodies. Considering its target markets, the Coral-200-Solar is really about making calls. It should be available in June.
Text and dial with the ZTE D92.

On the front, there's a display, a functional navigation array, and a keypad. Except for the solar panels on its rear face, the Coral-200-Solar largely resembles the ZTE C78 that's currently with MetroPCS. On a side note, a C78 is on my desk back in San Francisco awaiting a full review.
Unfortunately, hands-on time with the Coral-200-Solar was difficult. Apparently, the phone is as scarce in Barcelona as the Blue Earth.
When we wandered around the ZTE's booth the day before the announcement, it was nowhere to be seen, yet we did spy the aforementioned C78 and the interesting ZTE D92 slip phone, which features a Fastap keypad that combines a full alphabetic keyboard and a standard numeric keypad. The D92 also offers Bluetooth, 3G, and a 1.3-megapixel camera.

- If the phone is left in sunlight all day with the solar panel up, will it be enough to keep the phone changed given normal usage?

- Definitely not. The typical current required for a phone is around 50 - 100 mA during use, depending on the electronics, screen size, etc. My 1.5 x 1 foot panel delivers at peak 115 mA. Therefore, considering how small this thing is, I don't see how it's possible it could deliver enough current to keep the phone at neutral charge during use. This thing is about the size of the solar panel on my flash light radiio, and it can't get enough sunlight to keep the radio going when the battery is dead. A radio uses much less current than a cell phone, btw.
