Abstract
The purpose of this report is to identify the functional PVM (Photovoltaic modules), Damage PVM, unused but functional PVM, free slots available for PVM in all three arrays, Capacity of the batteries, Damaged batteries and Functional batteries, Universal power supplies (UPS) under use and available but not currently used UPS, connectors and starters, relays and energy meters located at GIKI PV plant.
Note:
• Collection of PV Cells Integrated on a board is a called a PV Module.
• Combination of two or more PV modules in series or in parallel is called PV Panel.
• Combination of PV Panels either in series or in parallel is called PV array.
• Combination of PV array is called a PV Plant.
Drawbacks in the Present system
• Presently the PV system is feeding the loads through solar electricity only at day time; while the loads are feed directly through utility grid at the night and also the batteries are charged. In present case the batteries are become fully charged before the sun rise as soon the power generated by the PV plant reached a certain threshold i.e. 24 Volts the utility grid is disconnected and the loads are driven through the solar electricity. In such case if the required energy (for Loads) is greater than or equal to the energy delivered by the PV arrays the process go on perfect else the batteries are over charged which not only waste the generated solar electricity but also affects the batteries life time and performance.
• The present system is bulky, less efficient and complicated.
• Present system lakes the ability to provide some useful information e.g. energy produced and energy delivered by the system.
• In some cases the system is un-automated e.g. if some electrical damages occurs in the system you should have to manually shift it to the utility grid and for doing that you must need labor.
