System Introduction
A solar PV system is a clean energy conversion system that converts the solar energy into the electrical energy that is used in our daily life.. The working principle of this system is to use the photoelectric characteristics of silicon solar panels to convert the sunlight irradiated on the solar panels into DC power. The DC power generated by the solar panels is then converted into AC power by an inverter and that is further used to fulfill load demands.
PV Module
Includes solar panel, connectors, panel supports, solar cables etc., thus converting solar energy into DC electrical power.
Grid and other Electricity Generators
Acts as a secondary power source to fulfill energy demand in home and commercial applications. It supplies stable electricity for commercial or home use. Additionally, it can combine with the solar PV system, if additional energy is required.
Inverter
It convers the variable direct current (DC) output of a photovoltaic solar panel into alternating current (AC) that can be fed into a commercial electrical grid or used by a local AC electrical network.
Solar Batteries
They are used to store the electrical energy converted by photovoltaic solar panels in the form dc power. This power is utilized in time of need such as insufficient sun light at night or bad weather conditions. There are many types of products such as Lithium Ion, Gel and Lead-Acid batteries. Amongst them, lithium ion are the most favorable with longer life and high energy capacity
Loads.
Loads
They are classified in to normal and critical loads. Normal loadscan be turned off during a power outage. However, the critical loads require power supply to be guaranteed even during a power outage.
