A flexible laminated solar cell comprising a CIGS photovoltaic layer having two opposing generally flat first and second parallel surfaces; a first encapsulation layer placed on each of said first and second parallel surfaces; an encapsulation vapor barrier film placed on each of said first encaption layers; a second encapsulation layer placed on said encapsulation vapor barrier films; and a third encapsulation layer placed on at least one of said second encapsulation layers. The laminated structure with encapsulation layers protects the CIGS photovoltaic layer against moisture and atmospheric pollutants. The CIGS laminated structure is used in a versatile portable solar charger provided with user interfaces to monitor and control the charger and devices or features contained therein.

Embodiments of the present invention are directed to a method for cleaning a wind turbine blade or a solar panel with a wind cinch device. The method includes applying a cleaning solution to a surface of a wind turbine blade or solar panel; affixing a wind cinch device around a high point of the wind turbine blade or solar panel; applying tension to one or more lines attached to the wind cinch device to control the pressure the wind cinch device applies to the surface of the wind turbine blade or solar panel; and applying tension to the one or more lines attached to the wind cinch device to pull the wind cinch device from the high point on the wind turbine blade or solar panel to a low point on the wind turbine blade or solar panel. Other embodiments of the present invention are directed to a Wind Cinch device. The Wind Cinch device includes a main body, the main body being an elongated member having a cleaning surface sufficient in length to form a loop around a wind turbine blade when wrapped around a wind turbine blade. The Wind Cinch device also includes a plurality of rigging points, each rigging point adapted to receive a line. Applying tension to one or more of the lines attached to the rigging points changes the circumference of the loop formed by wrapping the wind cinch device around the wind turbine blade.

A machine for cleaning solar panels includes a first X-axis device, a second X-axis device, and a Y-axis cleaning device. The first X-axis device includes a first track and a first moving device. The first moving device moves on the first track. The second X-axis device includes a second track and a second moving device. The second moving device moves on the second track.
