Nowadays, humanity is the development of industry due to improved quality of life required a lot of energy, so the energy consumption is increasing. But most of the energy is relying on coal, oil, natural gas and fossil fuel. As a result, the depletion of fossil energy resources, rising oil prices, increasing amounts of carbon dioxide emitted in the atmosphere due to global warming and the Kyoto Protocol to curb environmental pollution was adopted. So most of advanced countries are involved in a variety of investment in renewable energy research and development for expanding the use of clean energy and reducing a fossil fuels use.
PV system is the energy source of unlimited and it don''t need transport of fuel, mechanical operation and the local temperature. Also PV system''s advantage is that maintenance of PV equipment, the choice of equipment and installation work are easy.
PV generation method is using solar energy to convert sunlight directly into electricity. Its initial investment is higher than fuel power generation. We have to require studying about PV generation that decrease the installation cost of PV system and improve the output efficiency. Because of the efficiency is affected by weather conditions.
To increase the efficiency of the cell, PV MPPT control is control of the power conversion system and method to increase the efficiency of the solar cell module so that the normal direction of the sun and always keep track of the sun and a method are employed for improving the efficiency of PV system.
In this paper, the proposed 1kW dual-axis tracking PV system is made using a light sensor and control of a solar tracking device and than it analysed 1kW dual-axis tracking type PV system outputs and 1kW fixed type PV system outputs.
