Abstract
The long-term performance of various systems was determined and the economic aspects of solar hot waterproduction were investigated in this work. The effect of the collector inclination angle, collector area and storage volume was examined for all systems, and various climatic conditions and theirpayback period was calculated. It was found that the collector inclination angle does not have a significant effect on system performance. Large collector areas have a diminishing effect on the system'soverall efficiency. The increase in storage volume has a detrimental effect for small daily load volumes, but a beneficial one when there is a large daily consumption. Solar energy was found to betruly competitive when the conventional fuel being substituted is electricity, and it should not replace diesel oil on pure economic grounds. Large daily load volumes and large collector areas are ingeneral associated with shorter payback periods. Overall, the systems are oversized and are economically suitable for large daily hot water load volumes

Resumen (Extracto)
En este trabajo se determinó el rendimiento a largo plazode varios sistemas y fueron investigados los aspectos económicos de la producción de agua caliente solar. El efecto del ángulo de inclinación del colector, área del colector y el volumen dealmacenamiento se examinó en todos los sistemas y se calculó el de diversas condiciones climáticas y el de sus periodos de recuperación. Se encontró que el ángulo de inclinación del colector no tiene un...
