New Solar Panel Promises to Cut Energy Costs in Half

[Daily Tech] A Pasadena, Calif., company has applied to patent a new solar panel that can produce electricity at half the cost of conventional rooftop panels. According to the MIT Technology Review, Soliant Energy’s new Heliotube panel produces the same amount of energy as traditional solar arrays used in residential electrical systems, however a unique design reduces the amount of expensive photovoltaic material by almost 90 percent. Semiconductor- based photovoltaic (PV) material is needed to perform the actual conversion of solar energy to electricity inside a solar array, but the material is costly to produce.
