Solar Panels Efficiency Improvement Through Orientation Monitoring by Non Contact Method using TMR Sensor

The need for renewable resources has become cru-cial as a result of the escalating rate of energy consumption, the finite supply of fossil fuels, and the growing problem of pollution. Solar energy, in particular, has gained significant traction among renewable resources due to the abundant solar potential present around the world. This paper presents a novel technique of position monitoring and solar tracking of a PV panel with the help of non-contact Tunnel Magneto Resistance (TMR) sensor. Sun tracking of the Solar PV system enhances the energy production and in case of Solar thermal applications like parabolic trough and dishes it is essential. The tracking of sun and system orientation uses different types of sensors and actuators. The sensor size, precision, cost, and the gathered information from the sensor is import. In this research Tunnel Magneto Resisters (TMRs) sensor is used to determine the PV system one axis orientation. The training data sets are created through tests at a curved surface with different measured radial distances. The validation results showed the Bx, By Bz axis error values as 0.1, 0.3 and 0.5 percent maximum in the position measurement.
