Why do photovoltaic panels have orientation problems?

Authors to whom correspondence should be addressed. After installing a solar panel system, the orientation problem arises because of the sun’s position variation relative to a collection point throughout the day. It is, therefore, necessary to change the position of the photovoltaic panels to follow the sun and capture the maximum incident beam.

How are photovoltaic panels tracked?

They can also be distinguished by two tracking techniques: The MPPT (maximum power point tracking) method which is based on an algorithm to find the maximum power curve of the photovoltaic panel, or the sun tracking system, which is based on the orientation of solar panels throughout the day to better exploit the photovoltaic cells [4, 5].

How a solar tracker can improve the efficiency of a photovoltaic panel?

But the continuous change in the relative angle of the sun with reference to the earth reduces the watts delivered by solar panel. In this context solar tracking system is the best alternative to increase the efficiency of the photovoltaic panel. Solar trackers move the payload towards the sun throughout the day.

Are solar tracking systems a good alternative to photovoltaic panels?

In this context solar tracking system is the best alternative to increase the efficiency of the photovoltaic panel. Solar trackers move the payload towards the sun throughout the day. In this paper different types of tracking systems are reviewed and their pros and cons are discussed in detail.

How do photovoltaic panels work?

The first system uses two actuators to move a mobile platform in order to optimally position the photovoltaic panel in relation to the sun’s position in the sky. The optimal position is predefined for each day, hour of the day and the geographic position inside the PLC that controls the two actuators.

How to improve photovoltaic conversion efficiency?

The most effective method is solar tracking systems . Also, photovoltaic conversion efficiency can be increased by installing additional components such as cooling systems, maximum power point tracking systems, and solar tracking systems , .
