photovoltaic panels: Those talking points include the assertion that solar power is wildly inefficient, something director Jeff Gibbs demonstrates by visiting a solar farm in Michigan where photovoltaic panels convert just under 8 percent of the energy in sunlight to electricity, according to National Observer. But that efficiency rating is, as the photovoltaic-focused publication PV Magazine puts it, from another solar era Today's typical silicon solar panels operate at around 22 percent efficiency. Following the release of Planet of the Humans, the controversial new climate change documentary executive produced by Michael Moore, fossil fuel backed climate denial groups are bashing wind and solar power with renewed vigor, regurgitating the film's flawed, ancient talking points about the supposed poor performance and unreliability of these energy sources. And a new crystalline material called perovskite could soon raise the solar efficiency bar much further. But even the best semiconductors only capture a fraction of the light that strikes them. Solar photovoltaic cells the individual units that form a solar panel, like the shingles on a roof are wafer-like devices made of materials called semiconductors that are capable of converting sunlight to electrical energy.
