Photovoltaic stations in Algeria are considered an effective solution to overcome the problem of its lack electrical power and achieve goals sustainable development. The weather is continental, it has three main climate zones from north south, desert, which causes increase temperature photovoltaic modules thus a decrease their production power. Then active cooling systems that use water as medium represent good option reduce PV module generation rates. Due change south during four seasons, some periods, operation ineffective leads net output stations. Therefore, this manuscript aims develop advanced strategy for operating incorporated with highest Algeria. To goal, theoretical study was conducted on different regions express continental climate, namely, Algiers (36°46′ N, 3°03′ E), northern Algeria, Djelfa (34°40′ N 3°15′ E) central Ghardaïa (32°29′ 3°40′ southern get optimal strategies produced by simulation results presented average improvement generated panels reached 15.1%, 17.8%, 19.7% under conditions Algiers, Djelfa, Ghardaïa, respectively. integrated rate 7.65%, 7.13%, 4.91%

This research investigates the essential role of cooling systems in optimizing performance photovoltaic panels, particularly hot climates. Elevated temperatures on back surface panels pose a challenge, potentially reducing electrical output and overall efficiency. To address this, system employing water spray air was proposed examined across three scenarios. Results show consistent reduction panel temperature with implemented systems. The drop 24 °C (40%) increase power 13% indicates its effectiveness, peak efficiency observed during high ambient temperatures. When used, percentage ranged from approximately 20.5% to 35.4%. air-cooling achieves temperature, ranging 6 26%. Hybrid proves most effective substantially compared or alone. A detailed examination reveals significant increases throughout day. higher is achieved solar radiation hours highlighting effectiveness intense sunlight exposure. cumulative effect reinforces practical significance system, showing potential enhance daily energy yield. Efficiency trends consistently indicate without cooling. hybrid which appears as promising solution for diverse environmental conditions cases, improves by up 2%.
