Very similar to a NASA project prototype named Helios - It was just a solar celled wing with multiple propeller pods. Designed for unmanned remote controlled flight, it was meant to circle over a fixed spot for weeks together, offering communication services similar to a comm. satellite, but without the costs and risks of the launch involved.
It was beautiful to see it flying! Too bad it fell down to the sea when testing sometime ago, but NASA has photographs on their site.
