Stages of PV solar power inverter. The LM adjustable three terminal Positive voltage Regulator used here and it can give output voltage range from 1. Regulator LM output voltage Vout can be obtained as. IRF N Channel power mosfet from vishay siliconix used as a switching drivers for this inverter circuit. MOV Metal oxide Varistor protects electronic device connected at output.
Solar panel output voltage is directly fed into LM positive Regulator circuit and it is adjusted to give 12 volt output and Battery connected to this bias through 3A, 50V Schottky diode.
So varying electromagnet induced and primary winding coil produce EMF, hence we get Alternating current output. Your email address will not be published.

These processes include Photovoltaic PV cells installations, Inverter Installations, transformer installations and the installation of string combiner boxes SCBs etc.
The solar Hybrid Power plant installed is a hybrid power system that uses a combination of solar PV cells, batteries and diesel powered generators as energy sources to meet the energy need of the various load centers on the University campus.
The solar PV cells array serves as the primary power source while the diesel powered generators serves as the power backup. Since the project is a hybrid installation, it becomes necessary to synchronize the power sources to increase efficiency of power supply and a reduced downtime.
The secondary power source turns ON automatically when the primary power source fails. During the installation of the primary source, rigid flat framed PV modules made of Poly-Crystalline were used because of its temperature resistive advantage.
Twenty 20 PV modules were wired together in series to form a table, two tables connected in parallel to form a String. The result shows that the power of each panel used was W while the output voltage varies between The total voltage per table was between to volts during the day. The total number of PV modules installed at the site was 12, Three sets of diesel Generators, comprising of two 1 MVA capacity and a 1.
Their output voltage is 0. The average daily power consumption stood highest at kW during weekdays and lowest at kW during weekend. The case is not totally different in Nigeria. In Nigeria, the on-grid energy comes majorly from natural gas which accounts for about 80 percent of the total energy mix. However, due to continuing challenges with grid infrastructure and the environment, a large proportion of the economy is not connected to the grid, while a good population depend on off-grid fossil-based sources such as diesel and petrol.
The aforementioned sources of power generation present many challenges to humanity and the environment such as pollution of harmful gases and green house affect which causes climate change. Therefore, the need for clean, reliable, and renewable source of power supply cannot be over emphasized.
Nigeria is blessed with abundant renewable power resources that are not sufficiently exploited. These renewable energy resources have the capability to change the power landscape of the nation and position the country on the path of industrialization.
The availability of renewable power resources in all parts of the country has been demonstrated in many studies.
Therefore, it www. Solar energy resource is available in all parts of Nigeria with the average irradiance of 5. The vast expanse of Sahel Savannah in the northern region of Nigeria is a sufficient land space to produce the power that meets the need of the country. With this huge solar energy resource, it becomes possible to generate solar energy sufficient to meet the electricity need of the University community. This project is the Federal Government initiative to provide alternative source of power supply to the University to create good atmosphere for effective teaching and research.
Before installing the modules, tables are constructed with Aluminum materials called the module mounting structures MMS. The MMS are surfaces that give a perfect angle of inclination for solar PV modules during installation.
The base metal of the MMS stood vertically at an angle of 90 degrees to the ground and the adjacent metal made 12 degrees with the base metal. Before attaching the inclined metal, the base metal was driven into the ground a depth of one meter, and a mixture of concrete and cement solidified the foundation.
Figure 1 show the installation of module mounting structure. Fig 1: Installation of module mounting structure MMS 2. Many photovoltaic cells are pre-wired together by the manufacturer to produce a solar module. During installation at the site, solar modules were wired together in series to form table. Two tables connected in parallel to form a string. Rigid flat framed modules made of Poly-Crystalline PV were used because of its temperature resistive advantage. The various tables were given unique codes as identifiers to indicate which inverter the tables are supplying.
Figure 2 is the project site showing PV installation on MMS while figure 3 is the full view of installed table. Table 1 gives the PV module information www. Of Module at site 12, Maximum power W Max. Power Voltage Power Current 8.
