A solar energy collector or tower adapted to position photovoltaic devices in urban and suburban settings is provided. The tower includes an elongated pole, a plurality of photovoltaic modules pivotally mounted to the pole at a plurality of elevations, wherein each of the plurality of modules includes a housing, and a plurality of photovoltaic devices mounted in the housing; a drive mechanism adapted to rotate each of the pivotally mounted photovoltaic modules; and a base assembly adapted to pivotally support the pole. The tower and modules are designed to minimize wind load. The photovoltaic modules include a solar energy heat exchanger having a plurality of photovoltaic devices mounted with a plurality of reflective surfaces positioned to concentrate solar energy upon the photovoltaic devices. The photovoltaic devices and reflective surfaces may be positioned on panels or pyramidal structures. Methods and devices for collecting solar energy are also included.
