Solar energy introduction

1. The document discusses solar energy and the essential components of a solar energy plant, including solar collectors, energy transport medium, energy storage, energy conversion plant, and power conditioning systems. 2. Flat-plate collectors are the most common type of solar collector and consist of an absorber plate and glass cover that collects heat from the sun which is transferred by liquid in tubes. 3. The main components are the absorber, glazing, tubes, structure, and insulation; water is commonly used as the transport liquid but antifreeze mixtures can also be used.
