The world is running out of the oil and natural resources with each passing day. Most of the electricity around the world is generated using natural resources. E-governments are trying to move the electricity production from natural resources to hydro and solar generation. For the places such as in the Middle East and deserted areas in Sindh district of Pakistan, where water resources are low and solar is superlative for generating electrical energy. The objective of this research is to implement, model, design and simulate the Photovoltaic Solar Monitoring (PVSM) systems. The simulation for the system is implemented on LabVIEW software and tests are carried out for certain values of input. All the details, expected outcomes, problems, and results are part of this research. The scope of this research is to obtain the results using real-time simulations performed in LabVIEW. The simulation performed in LabVIEW mimics the implementation of the advanced automation and control system technique Supervisory control and data acquisition (SCADA). The objective of this research work is to perform the essential simulation that is required to investigate current products for PV factors monitoring that influence solar panels efficiency. The goals are: to design and to develop a system for monitoring the PV solar systems using LabVIEW, to simulate the performance of PV solar system using the theoretical methods, to monitor system by means of LabVIEW and to show theoretical effects in the method of the curve of PV performance parameters. Implementing the interfacing technique at home level to monitor the local solar parameters helps in utilizing the solar generated energy in an efficient way.

Proposed Model

The maximum electrical energy conversion efficiency of the Solar PV panel is up to 22% in normal conventional roof- top system under the temperature of 25˚C on Standard Test Condition (STC). In Indian climatic conditions, the atmospheric temperature is mostly above 35˚C to 45˚C, it incites 35˚C to 80˚C temperature on the PV panel. The black body of the PV panel absorbs more heat. This temperature affects the electrical efficiency of the panel significantly. This paper proposes the mathematical modelling of the solar PV panel for different solar irradiation and the temperature. The experimental evaluation is conducted in the latitude of 11.36 (N) and longitude 77.82 (E). The testing and monitoring was done with LabVIEW based National Instruments hardware such as NI cDAQ-9178, NI DAQ - 9227 and NI DAQ 9225. The comparative study between the simulated result and real time hardware results are discussed in this paper. The test result shows that the output of the proposed model mismatches with the experimental output of the solar PV panel due to the negative correlation between the efficiency and temperature for variable irradiation condition. It shows a power difference of 9.41W between the output of the proposed model and the experimental setup.

Subject The outlook for the solar photovoltaic sector in China. Significance The EU's decision last month to remove tariffs on imported Chinese solar panels follows a US move to increase tariffs. It also comes at a time when international prices for panels are falling in response to a reduction of subsides for the deployment of solar photovoltaic (PV) capacity in China. Impacts Falling prices will stimulate further installation of solar PV capacity across the world, especially in sunny regions. Chinese manufacturers will further expand their capacity both at home and abroad. Non-Chinese PV manufacturers will find their profits squeezed even further unless they are protected by import controls. The rate of deployment of new solar PV capacity within China will decline, but still remain substantial.

Waste Tyre

The increasing demand of natural resources for the concrete production has impacted the surroundings and the concern to protect these natural resources is increasing. Lately, handling and management of scrap is the primary issue faced by the countries worldwide. The waste problem is the most important problems facing the world as a source of the environmental pollution. One of the censorious wastes to be control in today is ‘waste tyre’ because; recent development in transportation has create big number of vehicles, which produce huge quantities of used tyres. Disposing such waste tyres is a critical waste management concern around the world at the moment. Various research work had been conducted in the past which had results that showed reduction in the mechanical energy of the concrete. The motive of this study is to use the reshaped waste tyre rubber as partial alteration of coarse aggregate in the concrete and to examine the outcome of providing an mooring hole of10mm in dia on the surface of the rubber gravel which makes the cement plaster to form a cylindrical mooring between the gravel and the concrete as well work as are bar to the rubber gravel thereby, increase withstanding power to failure under load which simultaneously increase the strength. The partial replacements of coarse aggregates are done at 0%, 5%, 10%, 15% and 20% by quantity of coarse gravel. The resulting concrete beams are tested for the physical characteristics of concrete. The Comparison of flexural response of beams are made with ordinary Portland cement concrete (OPCC)and Reshaped Waste Tyre Rubber Aggregate Concrete (RWTRAC)for various compositions of Reshaped Waste Tyre Rubber Aggregate replacement to coarse aggregate. Consequently the tests on RWTRAC beams of 10 % rubber aggregate replacement are conducted and results indicated that all the beams are failed in pure bending region and gives deflection nearly same as the conventional beam with the influence of the ultimate moment. Based on the observations during testing, the beams failed in pure flexural compression failure mode. Ductility factor of RWTRAC beam also showed enhanced performance when compared with the performance of conventional concrete. After testing it is inferred that till 10% of RWTRA replacement, the compressive and flexural strength of concrete is nearly same as the conventional concrete, but from 10 to 20% the strengths are abruptly fallen.

Near Future

At present, the problem of environmental protection has come to a global level. In conditions of globalization of the world economy, population growth, massive urbanization, the level of exhaustion of natural resources increases. The requirements for resources used in production or for the organization of favorable social conditions far exceed the speed and volume of natural replenishment. This leads to the inevitable depletion of natural resources, which causes such problems as resource shortages, water and air pollution, lack of freshwater, climate change, loss of biodiversity, and so on. Proceeding from the aggravation of the listed issues, recently the concept of a "green" economy has been actively promoted in significant international platforms, in the world social-political and scientific circles. The growth of the popularity of the concept of a "green economy" is largely due to the numerous crises that the world faced, including Ukraine, in recent years, – above all, ecological, financial and economic. The implementation of the new green course involves minimizing the use of non-renewable resources for electricity production through investments in renewable energy sources. One more pressing issue related to the "green economy" is energy saving. Today, Ukraine's economy depends on the energy sources that need to be imported. In this regard, the problem of energy supply has always been and is one of the most urgent. Only through constant search for internal reserves, using work on technologies that in turn will reduce the energy intensity of productions, and using alternative energy projects will help to change the situation in the near future for the better. Ukraine has all the prerequisites for intensive development, extraction and use of non-traditional energy sources. The transition of the Ukrainian industry to a market economy makes large and enterprises of all sectors and leaders of all ranks think about the need to save fuel and energy resources.

Availability of electrical energy plays a dynamic role in the social and economic development of any country. The energy mix in Pakistan is majorly dependent on the non-renewable energy sources which are imported,which results a short of electricity production while the consumers are facing a load shedding of 10-12h/day. This technological revolution, regulatory environment and changing economic conditions increase theimportance of Distributed Generation. Distributed Generation not only meets the energy requirements of any country but also improves the various issues such as saving in cost, reduction in technical losses, improvement in the power quality, reliability and security, reduction in power losses and environmental concerns to decrease the greenhouse gases. This paper presents the comparison of the energy utilization and its price between the existing low voltage system and the proposed solar PV system integration. It is seen that with the integration of an optimized PV system we will not only meet the energy requirement of our existing system but also inject some amount of energy in access to the national grid. Also a cost to benefit ratio of 2.63 is calculated which means the cost of this modification can be reversed in a time less than 3 years while the normal life of a PV system is taken as 25 years

Solar panels are used to convert the energy from sunlight to electrical energy. The different impacts on the solar panel which influences the productivity of the solar panel are Sun movement and dirt which generate the fundamental impact on solar panel. Because of those impacts, less yield generated by solar panel so to increase the effectiveness of the solar panel is by utilizing tracking and cleaning technique. There is a framework which is mix of tracking and cleaning. In this cutting-edge world, power is likewise added to the most fundamental requirements in everybody's day to day existence. With the expanding request of power, destruction of the natural resources is done and will be used for energy generation. To adjust the shortage of natural resources unconventional fuels are used for power generation and are used by the most part of world. Among all the unconventional fuel sources, power created by solar panel energy is broadly utilized. The abundancy of this type of energy is more all around the earth. A framework which tracks sun as well as automatic washing of solar panel with automated instructions is required. The instrument requires a LDR for following the sun and for cleaning wiper module is required. Regarding every day energy production, the sun tracking - cum cleaning plan gives more energy output when contrasted with the fixed PV module. Without this framework this cleaning work is done by man force which is good for small scale but for large scale like power plant it is very difficult. Then led display is required to display the result of the framework.
