Since I started working on Solar Energy I realized most of the articles were very long and sometimes difficult to understand, Hence i have written up a small summary and frequently asked questions so you understand Solar Energy in Just a Minute!
Solar Energy basically works by producing electricity using sun’s energy to power your homes or your businesses.
Our sun is a nuclear reactor by nature. It discharges small bundles of energy called photons, which travel 93 million miles from the sun to Earth in about 8.5 minutes. In an hour, enough photons reach our planet to create enough Solar Energy to hypothetically fulfill worldwide energy demands for a whole year.
Right now photovoltaic power or Solar Power represents just five-tenths of one percent of the energy used in the United States. In any case, Solar power is innovating and developing at a good pace, and the expense of installing solar panels is dropping quickly, so our capacity to capture the sun’s enormous energy is rising rapidly.
A 2017 report from the International Energy Agency demonstrates that solar energy has turned into the world’s quickest developing source of energy – pointing out the first occasion when Solar Energy’s development has outperformed that of every single other fuel. In the coming years, we will all appreciate the advantages of Solar Power somehow.
How do Solar Panels Work?
At the point when photons hit a sunlight based cell, they push electrons free from the electron shells of their molecules. When electrodes are connected to the positive and negative sides of a cell, it shapes an electrical circuit. At the point when electrons move through such a circuit, they produce Electricity. Solar Panel is made using multiple cells, and a number of solar panels can be wired together to frame what is known as a Solar Array. The more panels you can set up, the more energy and hence, more electricity you can hope to create.
What Are Solar Panels Made Of?
Photovoltaic (PV) Solar Panels are comprised of numerous solar cells. Solar are made up of semiconductors, such as Silicon. They are built with a positive layer and a negative layer, which together make an electric field, same as in a battery.
How is Electricity generated from solar panels to power your home?
PV Solar Panels produce direct flow (DC) form of electricity. With DC power, electrons stream in a single direction around a circuit. The following example demonstrates battery lighting up a bulb. The electrons move from the negative side of the battery, through the light bulb, and come back to the positive side of the battery.
With AC (Alternating Current) form of electricity, electrons are pushed and pulled, alternatively switching course, much like the paddles of a cycle alternate. Generators make AC power when a curl of wire is spun beside a magnet. Many different forms of energy sources can “turn the handle” of this generator, for example, gas or diesel fuel, hydroelectricity, atomic, coal, wind, or even solar.
AC form of electricity was picked specifically for the U.S. electrical power grid system, mainly on the grounds that it is more affordable to transmit over long distances. Be that as it may, Solar panels make DC power. How would we get DC power into the AC lattice? We utilize what is known as an inverter.
What is the function of Solar Inverters?
A Solar Energy inverter takes the DC type of electricity from the Solar Array and uses that to make AC Electricity. Inverters resemble the brains of the system. Other than reversing DC to AC power, they have sensors which detect as well as protect from effects of Ground Faults and provide details of the system, including voltage and current on AC and DC circuits, current amount of energy generation and Maximum power point tracking that helps in making the most energy in all conditions.
Since its origin, Central inverters have leaded the solar industry. The invention of micro-inverters is one of the greatest innovation steps in the PV business. Micro-inverters are perfected for every Solar Panel, not for the complete Solar Array, as central inverters do. This empowers each solar panel to perform at its most extreme potential. At the point when a central inverter is utilized, having an issue on one solar panel (possibly it’s in the shade or gets dirt over it) can reduce the performance of the whole Solar Array Setup. Micro- scale inverters take care of this issue. In the event that one Solar Panel has an issue, the remainder of the Solar Array still performs effectively.
How does a Solar Panel system work?
Here’s a case of how a household solar system works. To start with, daylight hits a Solar Panel on the rooftop. The panels convert that solar energy into DC current, which streams to an inverter. The inverter changes over the power from DC to AC, which you would then be able to use in appliances at your home. It’s perfectly straightforward and clean, and it’s getting progressively productive and cheaper constantly.
So what would happen if you’re out of your home and the electricity being generated from the solar system is not being used? Also, what occurs during the evening when your Solar System isn’t creating power? Try not to stress, since you advantage through a framework called “net metering.”
A usual PV System which is connected to the grid, during maximum daylight hours, usually delivers more energy than the home’s needs, and that excess energy is sent back towards the grid for it to be used somewhere else. The client gets credit for the excess of energy delivered, and can utilize that credit to obtain electricity during the evening or on shady days. A net meter takes note of the energy sent as compared to the energy obtained from the grid. Discover more about net metering here.
