    Abstract: Data from the Ministry of Energy and Water indicate that in Angola only 70% of the population has access to electricity, with rural areas being the least covered. The rural environment, however, has local energy resources that, once harnessed, can contribute to solving the problem of electricity production, as an essential asset for the production ...

    Abstract: Solar thermal collectors are the key component of active solar cooling/heating systems. This article presents a theoretical study to evaluate the effects of optical parameters such as the transmission coefficient of the glass on the outlet temperature of heat transfer fluid. We have therefore developed a detailed model for flat plate solar collecto... Show More
