IIRC, the effiencieny of solar panels is around 2-5%, which is abysmal.

The current market leader in efficient solar energy modules is SunPower, whose solar panels have a conversion ratio of 19.3%[3]. However, a whole range of other companies (HoloSun, Gamma Solar, NanoHorizons) are emerging which are also offering new innovations in photovoltaic modules, with an average conversion ratio of around 18%.[citation needed] These new innovations include power generation on the front and back sides and increased outputs; however, most of these companies have not yet produced working systems from their design plans, and are mostly still actively improving the technology. As of January 14, 2009 a World Record efficiency level of 41.1% has been reached. Return on investment is within 10 years.
