An Interesting Report on Solar Panel Efficiency in Near Space Conditions

Posted by Ovidiu Sandru in Experiments, Solar Power on December 21, 2010

You don’t really have to be an accredited scientist to prove the world that you actually can do scientific experiments. All you need is passion, knowledge and a little financial effort. That’s how a team of San Diego engineering students succeeded doing an experiment that involved sending a balloon, solar panels, cockroaches and anti-freeze Cucujus beetles into near-space.

Israeli Company Builds Floating Concentrated Solar Panels To Help Clearing Lands

Posted by Ovidiu Sandru in Solar Power on November 19, 2010

Keeping the land clear for useful projects is vital to some countries that have limited space and that have to manage it as tightly as possible.
If those countries will want to rely on solar power in the future, they’ll have to find solutions for managing their solar fields and the land is just not proper for that in some cases. But water bodies are.

Suntech's New Power Optimizers Could Solve Solar Panel Efficiency Issues Related To Shades

Posted by Ovidiu Sandru in Solar Power on October 15, 2010

Solar panels are usually mounted in series, to sum up their voltages, and the resulting power is sent to a large inverter, which transforms the DC voltage into AC. One big issue with this scheme is that if shade falls on one panel, or it gets dirty, the inverter lowers the current of all the other panels, and causing power losses through inefficiency.
