6 FAQs about Sun Chasing Solar Photovoltaic Panels

Does sun-tracking pv shading protect glare from the Sun?

Sun-tracking PV shading elements integrated with windows are modeled and analyzed. Novel optimum sun-tracking methods and cell layout are first proposed. Annual energy generation and average efficiency are improved by 27.40% and 19.17%. Optimum sun-tracking methods reveal great ability to protect glare from the sun.

Do sun-tracking pv windows have a trade-off between mutual shading and performance?

Previous studies on sun-tracking PV windows strayed into the trade-off between tracking performance and mutual shading, failing to achieve the maximum energy generation. Here we first build integrated models which couple the performance of sun-tracking PV windows to the rotation angles.

Which sun-tracking methods are used in partially-shaded PV modules?

Here we mainly consider four sun-tracking methods, i.e. quasi-perpendicular one-DOF, optimum one-DOF, perpendicular two-DOF, and optimum VP-3-DOF sun-tracking methods. Since the performance of the partially-shaded PV modules varies with the pattern of cell layouts, here we consider both layouts of vertical stripes and horizontal stripes.

What is a PV shading system?

In reality, the PV shading elements in our models could be PV blinds (one DOF), or arrays of PV squares (three DOFs). The PV shading system can be installed within the cavity of a double-pane window in new buildings, or simply mounted in the interior window area of existing buildings, just like the installation of conventional window blinds.

How to choose the optimal Sun-tracking method?

Jayathissa et al. chose the optimal sun-tracking method by exploring all possible dynamic PV orientations . However, for simplicity, all PV panels moved simultaneously with discrete angles ( 15 ° ). Therefore, it cannot achieve a continuous sun tracking according to the solar position.

Do PV modules have shading effects?

Notably, we consider that the shading elements are covered with lightweight thin-film PV materials. In industry, thin film PV modules contain series-connected solar cells formed by laser scribing technology, which makes it difficult to integrate bypass diodes. Therefore, PV modules in shadows are possible to suffer from the partial shading effects.
