That source can be solar panels formed as a photovoltaic array positioned generally near the tower. Photovoltaic arrays have been deployed for telecommunication towers all over the world.

  • a moveable photovoltaic array assembly comprises a shuttle assembly and a photovoltaic array mounted on the shuttle assembly.

It will be appreciated that at some times in the year, the shadow cast by the tower will at least partially cover the photovoltaic array assembly at both the first position. At different times of the year, the shadow of the tower will at least partially cover the photovoltaic array at the second position. In both cases, shadow on the photovoltaic array greatly reduces energy output of the photovoltaic assembly.
