cpv modules according to embodiments of the present invention can be mounted on a support for use with a multi axis tracking system the tracking system may be controllable in one or more directions or axes to align the cpv receivers with incident light at a normal e g on axis angle to increase efficiency in other words the tracking system may be used to position the cpv modules such that incident light for example sunlight is substantially parallel to an optical axis of the optical element s that focus the incident light onto the cpv receivers because a tracked system can change its orientation through the day to follow the location of the sun a viewer at a single location may observe the cpv modules at an off axis angle such that the pv elements or cells rather than the cpv receivers are visible in an alternative arrangement the cpv modules can have a fixed location and or orientation whereby if viewed from an off axis angle the pv elements or cells may likewise be visible in some embodiments of the present invention the pv cells that capture diffuse light can include cadmium telluride and or alloys thereof in some embodiments of the present invention the pv cells that capture diffuse light can include amorphous silicon and or alloys thereof in some embodiments of the present invention the pv cells that capture diffuse light can include copper indium gallium selenide and or alloys thereof in some embodiments the cpv receivers can be.
