Analysis of a Flat-plate Solar Collector
INTRODUCTION Solar Collectors Solar collectors are the key component of active solar-heating systems. They gather the sun's energy, transform its radiation into heat, then transfer that heat to a fluid (usually water or air). The solar thermal energy can be used in solar water-heating
