The best use of the sun's energy is to make hydrogen, according to a Duke University researcher. Engineer Nico Hotz earlier this week detailed results from his research around a rooftop solar panel that generates hydrogen from the sun's heat. The hydrogen gas--which is made by breaking off hydrogen atoms from a water solution--can be stored and used to make electricity in a fuel cell. In his experiment, Hotz determined that his system creates more usable energy than solar photovoltaic panels which convert sunlight directly into electricity. He calculated the cost could be lower, too. There have been research efforts--and a commercial product from a company called Nanoptek --to make hydrogen from sunlight. Hotz's system, though, uses a new technique that relies on methanol, also known as wood alcohol, and a nano-engineered catalyst. Under the glass of Hotz's solar collector are copper tubes, coated with aluminum and aluminum oxide, which carry water and methanol. Once the liquid is heated to a sufficient temperature, a catalyst is added to cause hydrogen atoms to break off. That hydrogen gas is then piped and pressured for storage in a tank, where it can be drawn on to make electricity in a fuel cell.

Powerway solar off-grid system is designed for use in remote areas, far from public supply networks. It has various applications ranging from daily use such as traffic light operation, to communication and the supply of emergency energy.
Ford and solar-panel maker SunPower have created a solar-powered electric-car package. Buyers of Ford's electric vehicles will have an option to have SunPower's rooftop solar panels installed for about $10,000 after a federal tax rebate. The companies estimate that the 2.5-kilowatt array will generate enough juice, about 3,000 kilowatt-hours a year, to fuel acar for about 1,000 miles a month of driving. The "Drive Green for Life" program means drivers can cut the cord on fossil fuels by generating power during the day and charging at night, according to the companies. Ford plans to release an all-electric Ford Focus and its C-Max Energy plug-in hybrid in 19 states next year and in Europe in 2013.

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
