Trackers allows a continuous adaptation of the position of the solar panel with regard to the course of sun; the tracker can be monoaxis (to follow the daily course of sun, and bi axis to follow also the seasonal modification of the solar course; monoaxis tracker allows PV panels to reach an annual production of about 1900 kWh / year / Wp considering Mauritius climatic conditions, to compare with static PV pannels production, in ordrer of 1500 kWh / year / Wp. The capacity of resistance of trackers at the cyclonic risk must be taken into account as well as the return of investments (overcosts). Feedback experience not leading to the economic benefits expected.
