Directional support photovoltaic

What is a fixed adjustable photovoltaic support structure?

In order to respond to the national goal of “carbon neutralization” and make more rational and effective use of photovoltaic resources, combined with the actual photovoltaic substation project, a fixed adjustable photovoltaic support structure design is designed.

Can a dynamic photovoltaic envelope improve solar tracking in real weather conditions?

We describe two envelope prototypes and demonstrate autonomous solar tracking in real weather conditions. The dynamic photovoltaic envelope achieves an increase of up to 50% in electricity gains as compared to a static photovoltaic envelope.

Where is a dynamic photovoltaic building envelope mounted?

The envelope is mounted at the NEST building at the Swiss Federal Laboratories for Materials Science and Technology, in Dübendorf, Switzerland. Svetozarevic, B., Begle, M., Jayathissa, P. et al. Dynamic photovoltaic building envelopes for adaptive energy and comfort management.

What are the enabling components of the adaptive solar envelope?

The main enabling component of the adaptive solar envelope is a two-axis hybrid soft/hard-material pneumatic actuator. The hybrid actuator allows for active control of the actuator’s stiffness and thus achieves stabilization of the module under windy conditions.

Should envelope operation be maximized for solar energy generation?

In the case of a less efficient heating or cooling system, the envelope operation should be maximized for reducing the operational hours of such systems, whereas, in the case of an efficient building heating or cooling system, the envelope operation is maximized for solar electricity generation.

How is thermal comfort based on the adaptive PV envelope?

The simulation of electricity generation, daylight and building indoor thermal comfort is conducted for all possible configurations of the adaptive PV envelope. The angle combination with the lowest net energy consumption, within the present comfort parameters, is chosen for each time step.
