    FAQs about Solar panels tilted in China

    Why is tilt angle important for solar panels?

    In China, solar photovoltaic (PV) installations in power plants and on rooftops are experiencing rapid growth and will continue for the next decades . Tilt angle is a critical parameter for installing PV panels. To maximize power generation, tilt angle should be adjusted to ensure that PV panels are exposed to direct sunlight.

    Why does the tilt angle of PV panels change?

    The optimum tilt angle at the same location changes periodically (Fig. 7) due to the Earth revolution around sun. In summer, when the sun shines more directly on the northern hemisphere, the tilt angle is generally small; winter is the opposite. Adjusting the tilt angle of PV panels according to the season helps capturing more energy.
