Long-term performance and economic aspects of solar hot water production were investigated. Collector inclination angle, collector area and storage volume were examined for all systems. Climatic conditions and payback period were calculated. Collector inclination angle does not have an effect on system performance. Large collectors diminish the system's efficiency. Increase storage volume has a detrimental effect for small load volumes, but beneficial with large consumptions. Solar energy was competitive with conventional fuels, and should not replace diesel oil on pure economic grounds. Large load volumes have shorter payback periods. Overall, the systems are oversized and economically suitable for large hot water load volumes.

Long-term performance and the economic aspects of solar hot water production were investigated. Collector inclination angle, collector area and storage volume were examined. Climatic conditions and their payback period were calculated. Collector inclination angle had no effect on performance. Large collector areas have a diminishing effect on system efficiency. Increased storage volume was detrimental to small volumes, but beneficial for large consumptions. Solar energy was competitive with electricity, and should not replace diesel oil on economic grounds. Large load volumes and collector areas have shorter payback periods. Overall, the systems are oversized and economically suitable for large hot water volumes.

Abstract
This work focuses on the investigation of performance and economics benefits from solar hot water production. System conditions such as collector inclination angle, collector area, climatic conditions and storage volume were varied, and their payback period was calculated. Inclination angles had no effect. Increases in storage volume depended on the daily load volume, but changes in solar collection were found to be the most influential factor for efficiency. Solar energy was found to be more economically efficient only when replacing electricity powered heaters. Overall, the systems are oversized and economically suitable for large daily hot water usage.

Abstract
Long-term performance and economic aspects of solar hot water production were investigated. Collector inclination angle, collector area and storage volume were examined; climatic conditions and their payback period was calculated. Collector inclination angle does not affect system performance. Large collectors reduce system efficiency. Increased storage is detrimental for small consumptions, but beneficial for large consumptions. Solar energy was competitive when substituted for electricity; it should not replace diesel oil on economic grounds. Large daily load volumes and large collector areas are associated with shorter payback periods. The systems are oversized and suitable for large daily hot water load volumes.

This study investigated the the economic aspects of solar hot water production and long-term performance of various systems. We examined the effect of collector inclination angle, collector area, and storage volume, and calculated various climatic conditions and their payback period. Collector inclination angle does not have a significant effect on system performance, while increasing collector area size impacts system efficiency. Collector areas and large storage volumes provide benefits with large daily loads. Economically, solar energy was found to be competitive with electricity, but is not economically competitive with diesel fuel. Overall, the systems are economically suitable for large daily hot water load volumes.

Abstract
Long-term performance and economic aspects of solar hot water production were investigated. Collector inclination angle, area and storage volume were examined for all systems. Knowing this, climatic conditions and payback period were calculated. Collector inclination angle did not have significant effect on system performance, but large collector areas diminish the system’s efficiency. Increasing storage volume was detrimental with small volumes, but beneficial with large consumption. Solar energy was competitive, but not a replacement for diesel oi. Large daily load volumes and areas give shorted payback periods. The systems examined are over sized and suitable for large load volumes.
Sam Castonguay
Long-term solar water-heating performance and economic aspects were investigated by calculating various climatic conditions’ payback periods after examining the collector inclination angle, area, and storage volume effects. System performance was unaffected by collector inclination angle. Large collector areas negatively affect the system’s efficiency. Large daily consumption benefits efficiency unlike increased storage for small daily load volumes. Solar energy is competitive with electricity but less economically advantageous than diesel oil. Large daily load volumes and collector areas are generally associated with shorter payback periods. Overall, the oversized systems are economically suitable for large load volumes.
Alex Zammit
This study’s objective was to determine the performance and economic aspects of solar hot water production. The payback period was calculated for various systems and climatic conditions. Collector inclination angle does not have a significant effect on system performance. Large collector areas have a diminishing effect on overall efficiency. Increase in storage volume has a detrimental effect for small loads, but is beneficial with large daily consumption. Economically, solar energy is competitive with electricity, but should not replace diesel oil. Large daily load volumes and collector areas are associated with shorter payback periods; therefore oversized systems are economically suitable.
Alexis Carambot
Long-term performance and economic aspects of solar hot water production were investigated. Effects of the collector inclination angle, collector area and storage volume were examined. Various climatic conditions and payback periods were calculated. The increase in storage volume is detrimental for small daily load volumes, but beneficial for large daily consumption. Large daily load volumes and collector areas are generally associated with shorter payback periods. Overall, oversized systems are economically suitable. Solar energy is truly competitive when the conventional fuel being substituted electricity, and should not replace diesel oil on pure economic grounds.
Edwin Torres
The economics of solar heated water and performance durability was investigated. Generally, large daily volumes and collector areas are associated with shorter payback periods. Effects of collector inclination angle, area, and storage volume variation on numerous climates and payback were recorded. Results show that collector inclination angle does not significantly affect performance, large collector areas diminish overall efficiency, and increasing storage volume negatively affects small loads, but positively affects large loads. Solar energy is a viable alternative to electricity, but cannot replace diesel. Overall, oversized systems are economically suitable for large volumes.
Anna Crews
Long-term performance and economic aspects of solar hot water production were investigated. Effects of the collector inclination angle, collector area and storage volume were examined as well. Various climatic conditions and payback periods were calculated. The increase in storage volume has a detrimental effect for small daily load volumes, but beneficial for large daily consumption. Large daily load volumes and collector areas are generally associated with shorter payback periods. Oversized systems are economically suitable overall. Solar energy is truly competitive when the conventional fuel is substituted by electricity, and should not replace diesel oil on pure economic grounds.

The effects of the collector angle, area and storage volume on payback period were examined in various climatic conditions. Results show the collector angle does not affect system performance.

Solar energy is competitive with electricity but not economically competitive with diesel. Large load volumes and areas are associated with shorter payback periods. Overall, the systems are economically suitable for large daily hot water load volumes.

Abstract
The collector’s angle, area and storage volume were examined for all systems. The long-term performances of various systems were determined and the economic aspects were investigated. It was found that the collector angle does not have a significant effect on system performance. Large collector areas have a diminishing effect on the system's overall efficiency. The increase in storage was beneficial only when there is large daily consumption. Solar energy was found to be competitive when the conventional fuel being substituted is electricity. Overall, the systems are oversized and are economically suitable for large daily hot water load volumes.
