Residential PV System: The Bright Future of Home Energy
Cost Savings
A residential PV system enables you to produce your own electricity at your home, thus granting you a greater independence from the power grid and its high rising energy costs. . This ensures a consistent and reliable energy supply at very low cost, providing peace of mind and convenience.
Energy Self-Sufficiency
A residential PV system enable you to produce your own electricity at your home, thus granting you greater a independence from the power grid. This ensures a consistent and reliable energy supply operating at low costs even during outages or emergencies.
Environmental Benefits
In comparison to energy production from fossil fuels, the energy produced by the PV system actively contributes to reduce greenhouse gas emissions and combatting climate change. Solar energy is clean, renewable, and doesn’t release harmful pollutants, helping preserve the environment for future generations.
Financial Investment
Installing a residential PV system is a wise financial decision with long-term benefits. As you generate your own energy, you are less-dependent on the power utilities with rising energy prices on the yearly basis. Besides this, the surplus extra energy can be sold to the utilities for financial incentives. . Additionally, the government incentives for residential PV systems increases your home’s value, thus makes it an attractive and profitable investment.
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.
