This chapter discusses a long-term energy performance assessment of five photovoltaic (PV) module technologies installed in semi-arid climate conditions installed in Algeria. The PV module technologies used in this study are three thin-film technologies namely the Copper indium selenide (CIS), the mono-crystalline heterojunction with intrinsic thin layer (HIT), and the tandem structure of amorphous silicon and microcrystalline silicon (a-Si_uc-Si) so-called micromorph, and two conventionnel technologies which are the multi-crystalline (mc-Si), and the mono-crystalline back contact (m-SI (B-C)). It was observed that the technologies suitable for such climate conditions are the m-SI (B-C) technology which degrades less than the other technologies with a degradation rate of −0.58%/year, followed by the mc-Si technology with −0.74%/year. In contrast, thin film technologies are not well appropriate for semi-arid climate conditions, however, the CIS technology stands out as the least suitable option due to its high degradation rate of −2.43%/year. Moreover, the micromorph technology exhibits a degradation rate of −1.73%/year, while HIT technology shows a degradation rate of −1.53%/year. It can be concluded that conventionnel PV module technologies are still the best choice for the semi-arid area.
