The investigation was carried out on collectors used for a period of 10 years or more. It is expected that the estimated service life for the coating is of the order of 30-40 years in an airtight solar collector with controlled ventilation of air, while in a non-airtight collector, the estimated service life is shortened to 5-10 years.
The energy saving referred to the use of solar collector has been calculated considering the average temperatures and solar inputs of the city of Palermo (Italy, 38° latitude) , . The useful primary energy saving ‘ Euseful ’ is estimated 6.6 GJ per year . The payback-time related to the studied equipment results lower than 2 years.
The energy and the environmental performances of one of the most common renewable technologies have been studied: the solar thermal collector for sanitary warm water demand. A life cycle assessment (LCA) has been performed following the international standards of series ISO 14040.
From 2002 to 2007 the thermal performance of solar collector has been increased by 29%, 39%, 55% and 80% for a mean solar collector fluid temperature of 40 ̊C, 60°C, 80°C and 100°C respectively. The increase of thermal performance is more significant for an increased solar collector fluid temperature.
The collector belongs to the category of passive solar device. The water tank and the absorbing surface are strictly connected, constituting a unique unit, and the thermal fluid circulation occurs with the natural convection. The internal fluid circuit does not need pumps and it does not cause power energy consumption.
INTRODUCTION For evaluation and comparison of solar collectors, many factors need to be considered: collector thermal performance and costs, lifetime of the collectors and decrease of collector performance due to aging. The thermal performance of a solar collector is fairly easy to assess.
