Sure, we've been frustrated by solar-powered iPhone chargers and amused by the irony of solar-powered lamps in the past, but that doesn't mean we're not looking forward to the day when we can meet our gadgets power needs without relying on fossil fuels. That's why we're pleased to note that a company called ReNu has just announced a solar panel that can be used to charge your iPhone or iPod, power the device's sound dock, or even keep your desk light shining sans mains power. Featuring a modular design, the panel can dispatched to your window to soak up the rays for 10 or 20 hours (depending on the amount of sunlight it receives) and then returned to your dock for about nine hours of music playback, recharge your iPhone (twice!), or provide about four hours of light with the LED desk lamp. Of course, most people are going to hang this thing in the window once, forget about it, and then spend the next several years powering their devices with the included AC adapter -- but at least they're trying, right? Available for pre-order now, the ReNu solar panel ($199) and the Renu panel / iPod dock combo ($249) both ship in February 2010, while the Side Light desk lamp ($89) ships in next March, and the Sound Dock ($149) should see the light of day sometime in April. Hit the read link to place that order, but not before peeping the galley below.
