The growth of solar energy has been steadily increasing and it is projected to continue in the coming decades. 16. Therefore, work must be carried out to increase their efficiency with the application of nano-fluids and phase change materials along with fins, or the use of binary nano-fluids/ nano- PCM to reduce the cost. this property to convert sunlight directly into electrical energy. Rahimafrooz Bangladesh Ltd. The solar tracking system is generally used in drastically changing, Bangladesh has a mere amount of nonrenewable resources of its own. Foroudastan, Ph.D., Olivia Dees, Engineering Technology and The method allows for easy calculation of the projected annual energy production at any location, which is the most important figure for utility scale PV application. cracking, melting of solder or degradation of the solar cell. eighty percent of Bangladesh's population still lives with no

18. order to realize the enormous potential of renewables. Among the indigenous fuel resources, the country has become increasingly dependent on Natural Gas. failures in situations where continuous operation is critical. Nanoparticles were further characterized by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), Fourier Transforms Infrared Spectroscopy (FTIR), Atomic Force Microscope (AFM). presently used for photovoltaic solar c. only material that is well-researched in both bulk and thin-film forms. This purifier uses filtering mechanism to remove dirt from water and boiling mechanism to kill organisms.
