Why the photovoltaic panels are not rotating

How does the orientation of a solar panel affect output power?

The orientation of a solar panel directly impacts the output power of a photovoltaic (PV) system. To increase the energy production per unit area, it is crucial to optimize the orientation of the solar array. Ideally, the solar panels are installed on 2-axis or 1-axis motorized trackers.

How do photovoltaic solar panels work?

While the photovoltaic solar panel may be perfectly aligned to receive the suns energy, it is a stationary object being fixed to either a roof or mounted directly onto a frame.

Can photovoltaic solar panels be used on a roof?

Photovoltaic Solar Panels can the be used as single panels on a buildings roof or walls pointing directly due south or west depending upon their location. While this type of solar panel orientation works fine for most domestic applications, in order to increase efficiency and reduce your payback period.

Why do solar panels need to be vertical?

For example, when the sun is lower in the sky during the winter months the solar panels orientation needs to be more vertical as the solar radiation passes through more atmosphere to reach the solar panel and therefore its intensity is reduced by the scattering and absorption effect of atmosphere and clouds.
