The computer code DOE-2 was used to simulate the energy consumption of four types of model houses constructed of clay bricks, concrete blocks, sandlime bricks, and prefabricated walls. It was found that a house built of clay bricks consumes 16, 23 and 25% less than one built of concrete blocks,...

This paper addresses the issue of the economic competitiveness of PV-powered irrigation when compared with conventional diesel powered pumps in the Kingdom of Saudi Arabia. The cost comparison gives a breakdown cost of a solar photovoltaic module of US$ 2.5 per peak watt.

In recent years, the computation of load and energy requirement in buildings, energy conservation studies in buildings, and the design of solar systems are not accomplished using long-term averages of weather data as inputs, but preferably with data-sets representative of the climatological...

The performances of one photovoltaic and two thermal panels during several months of outdoor exposure have been measured. For the photovoltaic panel, the average degradation rate of the efficiency was 7% per month, whereas, for the thermal panels, the average degradation rate on the optical...

For the last two centuries, fossil fuel has been considered and utilized as the main source of energy. However; the negative impacts of burning fossil fuel on the environment have forced the energy research continuity to seriously consider renewable sources of energy. Solar energy, in...
