Our sunlight is actually a natural nuclear activator. It launches little packets of energy known as photons that travel the 93 million miles from the sun to Earth in about 8.5 mins.

Every single hour, adequate photons impact our planet to create sufficient solar energy to theoretically satisfy global energy demand for an entire decade.

Currently photovoltaic electrical power accounts for just five-tenths of one percent of the energy used in the United States. But solar power modern technology is enhancing and the expense of going solar is dropping rapidly, so our capability to take advantage of the sun’s abundance of power is on the growth.

Due to 2017 report from the International Energy Company reveals that solar power has become the world’s fastest-growing resource of electrical power, marking the first time that solar energy’s growth has gone beyond that of all some other fuels. In the coming years, people will all be enjoying the benefits of solar-generated electrical energy in one way or another.

How do solar panels work?

Whenever photons hit a solar power 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. And then, whenever electrons flow through such a circuit, they generate electricity.

Numerous cells make up a solar panel, and multiple panels (modules) can be wired together to form a solar array. Therefore, the more panels you can deploy, the more energy you can assume to generate.

What are solar panels made of?

Photovoltaic (PV) solar panels are made up of several solar cells. Solar cells are made of silicon, such as semiconductors. They are designed using a positive layer and a negative layer, which together generate an electrical field, just like in a battery.

How do solar panels create electrical energy?

PV solar panels create direct current (DC) electricity. With DC electricity, electrons circulate in one direction around a circuit. This illustration reveals a battery powering a light bulb. The electrons migrate from the negative part of the battery, throughout the lamp, and return to the positive part of the battery. As a result, with AC (alternating current) electrical power, electrons are pushed and pulled, occasionally switching direction, very much like the cylinder of a car’s engine.

Generators produce AC electricity as soon as a coil of wire is spun next to a magnet. Lots of different energy resources can “turn the handle” of this generator, such as gas or diesel fuel, renewable energy, atomic, coal, wind power, or solar energy.

AC electricity was actually selected for the U.S. electrical power grid, mainly because it really is much less expensive to transmit over long distances. However, solar panels create DC electricity. How do we get DC electrical power into the AC grid? We utilize an inverter.

What does a solar inverter do?

A solar power inverter takes the DC electrical power from the solar array and makes use of that to make AC electrical power. Inverters are like the brains of the process. And then along with inverting DC to AC power, they also give ground fault protection and system statistics, including voltage and current on AC and DC circuits, power production and highest electrical power point tracking.

Central inverters have dominated the solar industry since the beginning. The overview of micro-inverters is one of the biggest innovation shifts in the PV business. Micro-inverters optimize for each individual solar panel, not for an entire solar system, as central inverters do.

This allows every solar panel to accomplish at maximum potential. Because when a principal inverter is used, coming with a trouble on one solar panel (possibly it’s in the shade or has gotten dirty) can drag down the functionality of the whole solar array. Micro-inverters make this a non-issue. Finally, if one solar panel comes with an issue, the rest of the solar array still carries out efficiently.

How does a solar panel system work?

Here’s an illustration of how a home solar energy setup operates. First, sunlight reaches a solar power panel on the rooftop. The panels modify the power to DC current, which flows to an inverter.

Hence the inverter transforms the electrical energy from DC to AC, which you can easily then use to power your home. It’s beautifully simple and clean, and it’s obtaining more efficient and affordable all the time.

However, what happen if you’re not home to use the electricity your solar panels are generating each and every sunny day? Furthermore what happens at night when your solar system is not producing electrical power in real time? Don’t worry, you still profit through a method known as “net metering.”

Actually, a regular grid-tied PV process, throughout peak daylight hours, frequently produces much more energy than a single buyer needs, so that excess energy is supplied back into the grid for usage elsewhere.

The customer gets credit for the excess electricity generated, and could make use of that credit to draw from the conventional grid at night or on cloudy days. Furthermore a net meter reports the electricity sent compared to the energy received from the grid.
