First of all, you have to understand how a solar panel works and the magic that exists between a ray of sun and its conversion into electricity. In this blog you will discover what you need to know about solar panels so you can have a wider vision of going solar in Australia.
Solar energy works by catching the sun’s energy and turning it into electricity for your business or home thanks to a solar panel (also known as photovoltaic cells). Solar panels are gadgets that were created to generate electricity using the sun’s light (which is composed of particles of light that are called “photons”). It’s important so say that solar panels are made up of several solar cells that contains silicon (in some cases called silicon cells) which acts like a semiconductor, constructed with two layers like a sandwich (one positive and other negative). Together, they create an electric field just like in batteries.
A solar panel converts the sunlight into direct current electricity so electrons can flow in one direction around the circuit. Then, with the help of a solar inverter, the direct current electricity is transformed into alternating current electricity (in this case, electrons are pushed and pulled reversing the direction, just like in the cylinder of a car’s engine). Also, the solar inverter provides information about the system stats, including voltage and current on AC and DC circuits, energy production, etc.
“But, how does a Solar Panel actually work?”
This is the process. First, sunlight hits a solar panel on the roof. The panels transform the energy to direct current, which flows to an inverter. The inverter converts the electricity from direct current to alternating current, which you can then use to power your home. That’s it! It’s a simple process that provides clean energy with almost no effort.
Photons make up sunlight, and when photons make contact with a solar cell, they create a reaction in the electrons within the atoms that creates an electric current. 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.
However, what happens at night when your solar system is not generating power in real time? No worries, you still benefit through a system called “net metering.” A typical grid-tied PV system, during peak daylight hours, usually produces more energy than needed so that excess of energy is fed back into the grid to be used elsewhere. And the good news is… the customer gets credit for the excess energy produced, so he can use that credit to draw from the conventional grid at night or on cloudy days. A net meter records the energy sent to be compared to the energy received from the grid.
