EQUIPMENT FOUND IN A SOLAR POWER PLANT
1. SOLAR PHOTOVOLTAIC PANELS
Solar photovoltaic (PV) panels are the cornerstone of any solar energy installation. These panels are composed of numerous solar cells that convert sunlight directly into electricity through the photovoltaic effect. When sunlight strikes the solar cells, it excites electrons, generating direct current (DC) electricity. The efficiency of PV panels is a crucial determinant in the overall energy yield of a solar power plant.
The performance and durability of these panels depend on various factors, including the type of material used, design, and the quality of manufacturing.
