A solar tracking system is disclosed, utilizing a photovoltaic device, for following the changing solar position. When the sun ceases to be the brightest object in the sky, such as during periods of partial cloud cover, and the system seeks to acquire the brightest spot in preference to the sun, the photovoltaic device is automatically overridden. The override system is clock-driven and moves the tracking system to approximate the solar position so that the sun can be immediately reacquired by the photovoltaic device when the sun re-energizes as the brightest object in the sky.
