cell temperature‚ the insolation level and array voltage. A maximum power point tracker (MPPT) is needed to operate the PV array at its maximum power point. In this thesis‚ we examine a schematic to extract maximum obtainable solar power from a PV module and use the energy for a DC application. This project investigates in detail the concept of Maximum Power Point Tracking (MPPT) which significantly increases the efficiency of the solar photovoltaic system.

2.3.4 How Does a Solar PV Works? The word photovoltaic is a combination of two words ‘photo’ which has a meaning of light and ‘voltaics’ meaning electricity. So‚ the scientific terminology photovoltaic technology describes to the use solar energy for the production of EPIA (2006). Figure 2. Diagram that shows how a solar PV works. The diagram above illustrates the operation of a basic photovoltaic cell‚ also called a solar cell. Solar cells are made of the same kinds of semiconductor materials

cell is a device which generates electricity directly from visible light by means of the photovoltaic effect. In order to generate useful power‚ it is necessary to connect a number of cells together to form a solar panel‚ also known as a photovoltaic module. Photovoltaic effect: What is a solar cell? How does it works How much energy can it produce? The photons (light particles) produce an electrical current as they strike the surface of the thin silicon wafers. A single solar cell produces

Unlike passive solar technologies‚ it usually contains a pump type moving device. Heat can be either consumed directly or stored in insulated containers with gravel‚ water‚ clay‚ or heat-absorbing chemical for later consumption when necessary.

Administration‚ the U.S. “is the birthplace to some of the word’s greatest clean energy technology”‚ but produces less than half of Germany’s clean energy program. In the last couple decades China has become “the worlds largest producer of solar modules”‚ using the United States’ solar technology breakthroughs. In a study conducted in 2009‚ the United States produced less than 15% of the world’s renewable electricity. In the past‚ computer technology began with large consoles with slow speeds.
