Comparative performance indices for solar batch water heaters

Conference · · Proc. Annu. Meet. - Am. Sect. Int. Sol. Energy Soc.; (United States)
OSTI ID:6322615
A simple method is developed to allow direct comparison of various solar batch water heaters. Certain system variables must be determined by calculation or measurement which may vary with season. These include Thermal Efficiency of Collection, Tank R value, Collector Surface to Tank Volume Ratio, Clear Day Collection Period in Hours, System Cost, and Installed Solar Heatings Fraction (optional). These variables are used to compute any one of four performance indices. This method allows a valid comparison not only between various solar batch water heaters but between other types of solar water heaters as well. This system may be used by consumers or designers to choose the most cost and performance effective options.
