What is Solar

BRIGHTENING THE WORLD FOR MORE THAN 22 YEARS

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.

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.

Why Solar

Solar energy  a clean source of energy . No greenhouse gas emissions are released into the atmosphere when you use solar panels to create electricity. And because the sun provides more energy than we’ll ever need, electricity from solar power is a very important energy source in the move to clean energy production.

 

Reasons why you should use solar power

Solar Power Is Good for the Environment

The most commonly known fact about solar energy is that it represents a clean, green source of energy. Solar power is a great way to reduce your carbon footprint. There’s nothing about solar power that pollutes mother nature. Solar power doesn’t release any greenhouse gasses, and except for needing a source of clean water to function, it uses absolutely no other resources. Hence, it’s safe and environmentally-friendly. Yet, people are still in doubt why solar energy is good.
Solar power is self-sufficient and installing solar panels on your roof is a safe and easy path to contribute to a sustainable future. Starting on your home is a great way to show you care about the environment

Solar Electricity Makes Your Home Go Off-the-Grid

Solar electricity prices serve as a great example of why there should be an increase in the use of solar energy. Traditional electricity relies heavily on fossil fuels such as coal and natural gas. Not only are they bad for the environment, but they are also limited resources. This translates into a volatile market, in which energy prices alter throughout the day.
Solar electricity boosts your electricity independence! By investing in solar power systems you can easily protect yourself against unpredictable increases in utility prices, and enjoy cheap electricity throughout the entire day – the sun will never increase its rates and it gives you energy security. Once you have solar panels up on your roof, you’ve technically reached an energy-independent status. Solar battery storage systemscan also help store electricity for nighttime and rainy days

Solar Power Can Use Underutilised Land

You may continue to wonder why solar power. With the increasing need of solar energy, it’s become easily accessible to most of us. Across countries, there are vast land that are far away from big cities or capitals, and are not used for anything at all.
With solar power, we can actually make use of the land and subsequently generate great value; solar energy provides a source of power for everyone. In this way, we don’t need to use high priced land that might be better suited for other applications.
You might have heard of solar farms – panels used to harvest solar energy in large numbers. This highlights perfectly how solar power makes use of underutilised land. For instance, a 45 acre solar farm has been recently built in the UK, and it’s able to power 2,500 homes.

Solar Power Causes Less Electricity Loss

Electricity needs to be transported from big power plants to end-consumers via extensive networks. Long distance transmissions equal power losses. Ever wondered what are solar panels used for? They’re on your roof to get energy from the sun. Rooftop solar power is helpful in increasing electricity efficiency, considering the short distance. Your energy becomes domestic and as a result you’re in control of your own billsand energy usage. Furthermore, solar power systems are durable, thus chances of service interruption are reduced.

Solar Power Improves Grid Security

When there are many of us switching to solar power, we are less likely to experience blackouts or brownouts. Every household in the India that have solar cells installed, functions as a small power plant. This, in turn, provides us with a greater electricity grid security, especially in terms of natural or human-caused disasters.

Solar Power Is A Free Source of Energy

The sun provides us with more energy than we could ever use, and no one can monopolise the sunlight. Your solar power system will start saving money from the moment it’s turned on, however, the advantages of solar power are best visible in the long-term. The longer you have your solar power system, the more you enjoy the benefits of solar technology and support the environment.
Aside from solar electricity, solar energy has a second application. We often associate solar energy with electricity, which is acquired through PV panels, but it’s also possible to use the energy generated by the sun for heating purposes. This process is accomplished by deploying solar thermal systems that simply convert the sunlight into heating solutions.
