PV tracker for small/medium scale projects didn't prove to be beneficial for large projects (benefits/ costs ratio and return of investments)

Reference: F 2.2

LEME Mitigation

Small or medium scale if increased energy efficiency is matching overcosts of investments

Estimated pay back time short term : 2-4 years, medium term: 4-6 years, long term : 6-8 years (*)

Trackers allows a continuous adaptation of the position of the solar panel with regard to the course of sun; the tracker can be mono axis (to follow the daily course of sun, and bi axis to follow also the seasonal modification of the solar course; mono axis tracker allows PV panels to reach an annual production of about 1900 kWh / year / Wp considering Mauritius climatic conditions, to compare with static PV panels production, in order 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.
