Study of analytical observations on energy matrix for solar stills

The extraordinary amount of solar irradiative energy all around the Earth has one of the motivational factors to work with such systems that utilize these for the services towards the benefits of mankind and its progressive growth, and that makes a powerful society and commendable nation. However, in the current era an unavoidable problem for the scarcity of potable water is going on, as brackish water keeps increasing faster than the approachable fresh water resources. For this, solar still systems for water treatment are one of the best solutions that utilize the solar energy as a prime source of working to the system. Out of those systems, energy matrix is one of the important performing factors that indicate the overall usability, payout characteristics, life cycle performing efficiency, etc. of the system. The current presentation reflects that active parameters undertaken in previous studies especially based on the energy matrix for active solar stills. A comparative result has been shown that results better in favor of nanoparticles and lower embodied energetic systems. Based on the overall performances and influencive parameters, a discussion and focused concluding remarks has been framed that suitably justifies the development towards this technology.
