Sun is the efficient source of electricity
As civilization progresses, the demand for energy grows, resulting to the exploitation of numerous conventional energy sources. Nonrenewable energy sources also contribute to greenhouse gas emissions and other environmental harm. Promotion of the development and deployment of green technology is required to limit and minimize environmental degradation.
Where The Savings Come From
The sun produces more than enough energy to meet the entire world's energy needs, yet unlike fossil fuels, it will never run out. Solar power's main constraint as a renewable energy source is our capacity to convert sunlight into electricity in an efficient and cost-effective manner. Solar, wind, biomass, hydro, and all other renewable energy sources that do not pollute the environment while in use must be adopted and used to replace all conventional energy sources.
Cost And Planning
Solar energy is a broad, abundant, cost-free, and environmentally friendly renewable energy source. Because solar radiation is a very abundant, clean, cost-free, and unlimited source of energy, it has the greatest promise for green technologies. A photovoltaic cell, often known as a solar cell, is used to convert solar energy into electrical energy.
Selection Checklist
Solar cells are made up of silicon-like semiconductors, and a PV solar panel is made up of a large number of solar cells. PV systems are classified into several categories. • Grid tied or grid Direct PV System• Off Grid PV SystemGrid tied or grid-direct PV systemThis is a simple solar system with a grid-tied inverter.
Step By Step Breakdown
There is no battery bank for storage in a grid-connected solar PV system. Only during the daylight power maybe generated and used from a grid-tied system. This system is extremely cost-effective, easy to construct, manage, and requires minimal maintenance.
Key Benefits
Solar panels typically produce more electricity than the loads require. As a result, instead of storing the excess electricity in the batteries, it can be returned to the grid. Levelized cost of energy of system can be reduced and extra revenue also generated by marketing excess generated power by solar panel.
Main Advantages
The main disadvantage of grid direct system is it can only be used during daytime. Power cannot be saved for power outages and other condition like cloudy weather. This drawback can be overcome by using battery bank to store the power, but it increases the overall system cost.
Overview
Standalone/off grid solar PV systemOff grid facilitate those customers who are unable to connect their load to the grid. In this system batteries used to store electricity which can be used during daytime and in emergency case. The advantage of this system is that it gives enough energy to household and is used to run the power system which are far from grid source.
How The System Works
It is more expensive and costly than direct grid system due to more components.
