WHAT ARE THE MOST AFFORDABLE AND RELIABLE OPTIONS OF RENEWABLE ENERGY?
What are the different sources of renewable energy available and which is most affordable and reliable option for the general population and common businesses in India and Gujarat?
The term renewable source of energy refers to a sustainable energy source that does not get depleted over time. This is a stark opposite of fossil fuels or non-renewable sources of energy, which are getting fast depleted.
While non-renewable sources of energy are limited, renewable sources are abundant. There is no chance of us ever running out of solar power and wind power, for example. Here’s a look at some of the most popular renewable sources of energy used by the general public and businesses in Gujarat and India.
Wind Energy is another popular renewable source of energy which is abundant in Gujarat. Here’s how it works: Wind power is harnessed wind power to rotate large turbine blades. This puts large generators into action, which generate electrical current, which is then distributed to homes and businesses. India can potentially generate 45,000 MW of power from wind energy.
India has been generating electricity from hydropower since the early 20th century. This is a renewable source of energy, which is obtained from the rapid movement of water in rivers, oceans, and waterfalls. India can potentially generate 1.5 lakh MW of electricity from hydropower, but currently, only 20% of the capacity is utilized.
Biomass is a form of energy that is obtained from organic materials. It is a renewable source of energy and found in abundance in rural areas of Gujarat and the rest of India. It is produced from animal manure, food waste, agricultural crops and human sewage.
Solar energy is the most abundant source of energy in the world. It is especially available in plenty in Gujarat, where the sun beats down relentlessly all the time. Solar energy is the most important type of alternative source of power, which is growing at a rate of 50% every year.
Go to any village or town in Gujarat, you will be greeted by the sight of solar PV systems on the rooftops of homes, buildings, schools, shops and offices. Solar energy can be used to generate power. It can also be used for cooking, water heating, lighting, running water pumps and so many other purposes.
ANP Solar installs home solar systems across the state of Gujarat and the rest of India. We have been a part of the mammoth effort to transform Gujarat through solar power. Solar energy works by capturing the sun’s energy and turning it into electricity for your home or business.
Our sun is a natural nuclear reactor. It releases tiny packets of energy called photons, which travel the 93 million miles from the sun to Earth in about 8.5 minutes. Every hour, enough photons impact our planet to generate enough solar energy to theoretically satisfy global energy needs for an entire year.
Currently photovoltaic power accounts for only five-tenths of one percent of the energy consumed in the United States. But solar technology is improving and the cost of going solar is dropping rapidly, so our ability to harness the sun’s abundance of energy is on the rise.
A 2017 report from the International Energy Agency shows that solar has become the world’s fastest-growing source of power – marking the first time that solar energy’s growth has surpassed that of all other fuels. In the coming years, we will all be enjoying the benefits of solar-generated electricity in one way or another.
How Do Solar Panels Work?
When photons hit a solar cell, they knock electrons loose from their atoms. If conductors are attached to the positive and negative sides of a cell, it forms an electrical circuit. When electrons flow through such a circuit, they generate electricity. Multiple cells make up a solar panel, and multiple panels (modules) can be wired together to form a solar array. The more panels you can deploy, the more energy you can expect to generate.
What are Solar Panels Made of?
Photovoltaic (PV) solar panels are made up of many solar cells. Solar cells are made of silicon, like semiconductors. They are constructed with a positive layer and a negative layer, which together create an electric field, just like in a battery.
How Do Solar Panels Generate Electricity?
PV solar panels generate direct current (DC) electricity. With DC electricity, electrons flow in one direction around a circuit. This example shows a battery powering a light bulb. The electrons move from the negative side of the battery, through the lamp, and return to the positive side of the battery.
With AC (alternating current) electricity, electrons are pushed and pulled, periodically reversing direction, much like the cylinder of a car’s engine. Generators create AC electricity when a coil of wire is spun next to a magnet. Many different energy sources can “turn the handle” of this generator, such as gas or diesel fuel, hydroelectricity, nuclear, coal, wind, or solar.
What Does a Solar Inverter Do?
A solar inverter takes the DC electricity from the solar array and uses that to create AC electricity. Inverters are like the brains of the system. Along with inverting DC to AC power, they also provide ground fault protection and system stats, including voltage and current on AC and DC circuits, energy production and maximum power point tracking.
Central inverters have dominated the solar industry since the beginning. The introduction of micro-inverters is one of the biggest technology shifts in the PV industry. Micro-inverters optimize for each individual solar panel, not for an entire solar system, as central inverters do. This enables every solar panel to perform at maximum potential. When a central inverter is used, having a problem on one solar panel (maybe it’s in the shade or has gotten dirty) can drag down the performance of the entire solar array. Micro-inverters, such as the ones in SunPower’s Equinox home solar system, make this a non-issue. If one solar panel has an issue, the rest of the solar array still performs efficiently.
How Does a Solar Panel System Work?
Here’s an example of how a home solar energy installation works. First, sunlight hits a solar panel on the roof. The panels convert the energy to DC current, which flows to an inverter. The inverter converts the electricity from DC to AC, which you can then use to power your home. It’s beautifully simple and clean, and it’s getting more efficient and affordable all the time.
However, what happens if you’re not home to use the electricity your solar panels are generating every sunny day? And what happens at night when your solar system is not generating power in real time? Don’t worry, you still benefit through a system called “net metering.”
A typical grid-tied PV system, during peak daylight hours, frequently produces more energy than one customer needs, so that excess energy is fed back into the grid for use elsewhere. The customer gets credit for the excess energy produced, and can use that credit to draw from the conventional grid at night or on cloudy days. A net meter records the energy sent compared to the energy received from the grid. Find out more about net metering here.
