In the present work, a prototype of a new type of solar collectors, which called Direct Absorption Solar Collector, was built and its thermal performance is experimentally compared with conventional flat plate solar collector under transient and steady state conditions. Different volume fractions of multi wall carbon nanotubes in water and ethylene glycol mixture (70%:30% in volume) were used a...

I this Viewpoint, we show that it is sufficiently easy and cheap to fabricate a perovskite solar cell that this can be done as an undergraduate laboratory experiment. Solar cells, which have been around since the 1950s, are considered as a prominent source of renewable energy in the future. Conventional solar cells, which are used in rooftop applications, are based on single-crystal silicon and...

A solar still is a viable option when the demand of potable water does not exceed more than 3 litres. Enhancement in distillate output from the solar still is a main goal of many researchers all over the world. In this research, the effect of copper and aluminium plates on distillate output is investigated experimentally as well as theoretically at different water depths under the same climate ...

Considering the difficulty of power supply for automatic observation equipment in polar regions, this paper introduced a small standalone renewable energy system with wind–solar co-generation as scheme. Mathematical models were given, including solar photovoltaic panels, wind turbines, irradiance, density, and assessment. ERA-Interim atmospheric reanalysis data used to evaluate resources, syner...

In this study, an artificial neural network based model for prediction of solar energy potential in Kerman province in Iran has been developed. Meteorological data of 12 cities for period of 17 years (1997–2013) and solar radiation for five cities around and inside Kerman province from the Iranian Meteorological Office data center were used for the training and testing the network. Meteorologic...

The presented review gives reliable information about the currently used measurement instrumentation in parabolic trough fields and recent monitoring approaches. usually built-in equipment solar field, clamp-on systems for flexible measurements of temperature flow, irradiance measurements, standard meteorological equipment, laboratory devices heat transfer fluid analyses instruments related to ...
