For many, the concept of being able to tap into the sun and produce energy that can power their home, business, or automobile is a mysterious phenomenon. Unlocking the power of the sun in just a few simple steps can not only save you thousands on utility bills but also help create a more sustainable world by reducing our carbon footprint. Here is how solar panels work to produce energy:
1. Solar Panel Technology
Solar panels work to convert sunlight into electricity that your home can use, reducing your electricity bills. Panels come in a variety of sizes and shapes, and use a range of solar cell technology. The very best panels work harder by maximizing every drop of solar energy available throughout the day. The very best solar panels on the market can produce 70% more energy than lesser solar panels over the course of 25 years*. Studies have shown that a solid copper foundation adds strength to panels, and ultra pure silicon delivers optimal solar energy conversion. In fact, the world record efficiency of 24.2% delivers 44% more power per square foot of solar panels, meaning that they work to produce significantly more solar energy that panels made from other materials. It's also imperative that your panels are engineered and tested to stand up to the world's harshest conditions, including temperature swings, battering winds, humidity, hail, and more. If the design or quality of the solar panel is inferior, it could mean that you'll be producing significantly less solar energy. A well-certified system has been shown to yield solar energy for more than 40 years.
2. Installing Solar Panels
Once you select the very highest quality solar panel technology, placement of the solar panels is key to generating solar energy. Some of the most popular locations for panel installation are on the roof of your home or business, surrounding areas on the ground, or a solar canopy. Your solar company will input your home's dimensions into a Computer Assisted Design (CAD) program to aid in assembling a permit submittal packet. Once the solar company has determined which location will generate the most solar energy and the number of panels will be installed, a typical solar system installation only takes a couple of days.
3. Monitoring The System
Once your system is installed, you'll immediately start producing solar energy that can be used to run your lights, computers, machinery, and any other electrical devices for your home or business. A utility meter tracks your energy use and counts both ways. You will earn credits for solar power produced but not used because it is pushed back into the utility grid. The utility grid still provides you with electricity at night, when you're not producing enough solar power, but any credits earned during the day cover that cost. Remember, the amount of solar energy you're producing can change throughout the year based on where you live and how much sunlight your panels are receiving on a daily basis. To check on how much solar energy your panels are producing you can use your online monitoring system to track production. If you notice a significant variation, notify your solar company to ensure everything is working properly.

Myths
We know solar like the back of our hand. That's why, when someone comes to us with a crazy myth about solar, we are more than happy to dismiss it.
Here are some of the most popular myths we like to bust:
* Solar doesn't work in cold or cloudy places. If that was the case, most of Europe would be without power for half the year and England would have no chance. All solar needs is UV light and cold solar panels actually work better!
* Solar is unreliable. This is one of the most common myths but solar is actually far more reliable than your utility company, particularly with off-grid systems which aren't affected by blackouts.
* Solar doesn't support the Australian economy. Sure, many of our solar panels are built overseas, but thousands of Aussies are employed in the local solar industry - installers, maintenance, sales.
* Solar panels are too high maintenance. False. They don't have any moving parts, so unless there has been some sort of damage you need checked, or your regular maintenance (including an annual clean), your panels should last as long as (or beyond) what the warranty states.
* You have to be rich to have solar. No, you don't. In fact it's more common for middle income earners to have solar. The good thing about solar is the long-term financial benefits are well worth the initial investment.
Misconceptions
Renewable Energy seems to be the way of the future. It's becoming more prominent every day, in both residential and commercial holdings, and countries all across the world are changing the way they operate to utilise the best of what they have for free - the sun, the wind, and water.
So what are the common misconceptions about solar energy?
1. Solar Energy isn't a 24 hour thing. Yes, it's true that solar relies on the sun to work and wind power relies on there actually being wind. But there are plenty of systems out there that have back-ups (they might be powered by another renewable source, or could be electric or gas) that will ensure you get the benefits of solar 24 hours a day, 7 days a week.
2. It's too expensive. Okay. We admit it. Getting solar on your home or business does cost more than connecting the electricity. But in the long run, you're going to save more than your solar cost you. According to the Clean Energy Council of Australia, based on a 3kW system - you'll save around $1000-$1200 per annum.
3. Solar systems are ugly and decrease the value of your home. This is simply not true anymore. There are a number of systems available that take up little space on your roof, but provide full benefits. Split-systems, for example can take up a small bit of space on the roof with the remainder on the ground. So your home remains looking amazing, but you get all the benefits of solar.

This article will address some of the most intriguing solar energy facts. Solar energy is generally one of the most ecologically sound and desirable sources of power these days. Let's get going with the obvious. Solar power has been in existence since the dawn of time. It has been used by microbial, plant, and animal life as a primary energy supply. Plants, using photosynthesis, create nearly all of the food on the earth and are at the base of the food chain. Furthermore the fossil fuels we rely on so heavily nowadays are created from plants and animals that lived a long time ago. Only in recent times have human beings been able to capture solar energy so that it may be utilized any time of day and night, and in any weather, stored and transferred.
Annually, the earth's atmosphere absorbs 3.85 million exajoules of energy from our sun. This most likely doesn't mean much to you, however by comparison, the entire use of electric energy by all people today around the world is just 56.7 exajoules per year. This indicates that within a few hours, the earth receives more energy from the sun than people expend during an entire year! Solar energy is a remarkably clean supply of energy simply because, in contrast to fossil fuels, making use of this kind of energy doesn't discharge carbon dioxide or other types of harmful toxins into the environment. Furthermore solar energy is collected by almost every single form of life. You've almost certainly never seen a reptile collect wood to start a fire, but you most likely have seen one lying on a rock to absorb solar energy. Solar power is probably the most environmentally sound energy option attainable right now.
Perhaps you may be wondering what exactly solar power is capable of doing for our environment. Every year, humans consume 467 exajoules of energy by utilizing several principal power sources: burning coal, gasoline, and oil, along with 'green' sources like wind, solar, and hydro energy. However, if we could capture just 10% of the sun's energy, we would have the capacity to replace all of the fossil fuel sources and have enough space for growth. Without any doubt solar energy facts like this make it clear how much better solar power is for the environment and how great the potential is for solar energy development.
Considering that you've seen some of the most remarkable solar energy facts and now have an understanding regarding what solar energy can possibly do for the environment, you'd probably want to know just exactly what solar energy is. To put it simply, solar energy is the heat and light energy emitted from the sun. The sun constantly generates vast quantities of energy into our solar system. Approximately 30% of the sun's energy that reaches the earth is immediately deflected by the atmosphere, and another 20% is absorbed into the atmosphere. However, around 50% of the energy actually reaches the earth's surface, where it fuels photosynthesis in plants, maintains both hot tropical and warm temperate climates, maintains the temperature of the ocean, and generally speaking keeps our planet alive. All of this is accomplished without creating any pollution or destruction of natural resources.
A lot of people don't understand how solar energy functions on the technical level, and so they wonder just what solar energy is going to provide to their homes, businesses, and communities. In the last three decades, solar energy technology has developed at an accelerated rate. Solar energy is gathered at a number of large power plants in the U.S., Spain, Australia, and in other nations, where it delivers power directly to the power grid. This implies that countless houses around the globe already get electrical power generated by the sun. One of several lesser known solar energy facts is that solar power can also be employed on a considerably smaller scale. Solar panels on households and businesses, can certainly create a percentage (or possibly all) of the power these buildings have to have. On an even smaller scale, solar panel systems are put to use in India and Indonesia to disinfect water, and compact solar burners and ovens are often employed in order to cook food in other regions of the globe. Solar energy might be employed to power practically any procedure you can visualize, from large-scale power generation for towns and cities to boiling a single pot of water.
What makes all of these different uses achievable is the development of solar energy systems. You will notice two standard varieties of solar energy technologies presently used today: solar thermal energy (STE) and photovoltaic (PV) energy. Solar thermal collectors just harness the heat or thermal energy generated by the sun. This thermal energy is generally used to heat water which in turn can easily be stored and used for common every day requirements or piped to a household heating system. STE may be stored by heating up or energizing a thermal mass that is designed to continue to radiate heat even when the sun isn't shining. Solar thermal collectors actually are significantly more efficient in comparison with photovoltaic collectors but on the other hand energy storage is somewhat more cumbersome. Photovoltaic solar panel systems produce electricity when exposed to sunlight. This electric current may be used immediately or alternatively stored by using batteries for later use. This is actually one of the more significant solar energy facts whenever you are dealing with PV energy systems. Battery storage is incredibly significant since it means it is possible to store solar power for use through the night or during cloudy or rainy days.
Solar energy is a very important alternative power source which can help us take care of our environment. It can also help to cut down our reliance on fossil fuels. You may be asking yourself just how big of an expense it is going to be for you to convert to solar power? Solar power is not really as costly as most people think. A total solar energy system for a house can potentially cost more than $30,000, having said that this does not really mean you will be paying that total amount. To begin with, you will discover lots of different incentive plans, which include tax credits, rebates and grants, that may reduce the price of installing solar panel systems by 30% or more. One other option you might wish to look into is a smaller solar energy system that just supplements your household power needs. A smaller sized system will cost considerably less, while still lowering your current energy bills, and it will certainly help make your home much more environmentally sound. Currently most electrical power is generated using fossil fuels. So lowering your use of electrical power from the area power company by 50% is actually an important step towards establishing a sustainable power grid.
In this article, we've made an effort to supply you with a number of helpful and thought provoking solar energy facts. While you contemplate these facts, also think about just how much value you put on the quality of the environment and on humanity's ability to preserve it. No matter if fossil fuels do not run out during the next 50 years, it's very likely that their continued use as our primary energy source is going to wreak environmental havoc. Investing in solar power now might not instantly help you save money, but your monetary investment can certainly provide an improved future for everybody under the sun.

If you are one of those who cares deeply about the usage of electricity for the endless electronic devices that we make use of today, solar energy is a good way or reassuring yourself that there is a way of carrying on with the same work but with the usage of a more noble mode of energy which is the solar energy.
The process of deriving pure energy from the sun is a great one and using it for various beneficial reasons is even better. Whoever invented it must have had the best interest in heart to bring in a change that would help the world in a massive way. The availability of this mode of energy in houses and various other sectors has brought in a real good change.
Let us have a look at some benefits of this solar energy:
• BEING CONCERNED FOR THE ENVIRONMENT
Adapting a method of using pure energy from the solar radiation is absolutely a very thoughtful way of protecting our environment. This is because this form of energy has the least hazardous impact on the environment, neither does it produce any harmful greenhouse gases nor does it pollute the water. It does not produce any sort of noise during its production and the environment hardly faces any difficulty.
• GOOD WAY OF REDUCING THE ELECTRICITY BILL
A very effective and generous way of curbing all those extra money that has been piling up on your bill, solar energy is just the way you should head to. There will be an immediate reduction in your bill when you generate your own electricity because you will be making much less use of the utility supplier. Plus, a thing that many people are not aware of is that you can earn by selling the unused electricity and that too a very generous amount.
• THIS MODE IS APPLICABLE EVERYWHERE
As long as you have the availability of sunshine, nothing can stop you from making use of this kind of energy. This is very helpful especially in the remote areas where access to electricity is very hard to get hold of. In these places solar energy is a blessing in disguise that helps them to carry on with their everyday work that would require energy.
• YOU GET A SECURED FACILITY OF THE GRID
When you get a grid which has the facility of a penetration of solar energy that is suitably high has a lot of centers for energy production. This ensures a stable security of the grid in case you face any sort of an overload, human or natural disasters.

You can calculate the size of the solar system and the number of necessary solar panels using a not so complicated algorithm. The numbers you have to put in the equation are your monthly electricity usage, the number of peak sun hours per day, and the power of a solar panel.
Calculating the solar system size for a 2000 kwh energy usage
To exemplify, let's start by assuming you need a solar panel system that can generate 2000 kwh per month. From the beginning, you should know that 2000 kwh per month is a quite a lot of energy, and you would need an impressive solar system to provide it. Although we use this number just for the sake of the exemplification, in case you do consume 2000 kwh per month, our advice would be to take some energy reduction measures and to remain connected to the electricity grid, just in case the solar system cannot keep up with the demand.
Now, you have to find out for how many hours per day your system will be able to produce enough electricity for your needs. The panels produce energy only when the sun is up in the sky, and it shines directly on them. At night, the panels do not produce anything. In the morning and in the evenings, when the sun is weak, the energy production is also insufficient. Depending on the area where you live, there might be 4-6 hours of peak sunlight every day, when the system will produce the necessary electricity, and sometimes even more than you need.
If you want to have 2000 kwh per month, it means you have to produce 2000/30 kwh every day, that is 66.66 kwh per day. Considering there are 4 hours of peak sun every day in your area, the solar system will have to produce 66.66/4 = 16.66 kwh per hour, and that means 16660 in watts. Now, different types of panels produce more or less energy watts. If you opt for one that produces 150 watts, then you will need about 111 solar panels. Yes, that is a lot.
To approximate the necessary space for such a solar system, you have to know that, in order to generate 2000 kwh per month, you need a system of 24.8 kwp (kilowatt peak). Every 1 kwp needs about 100 s.f. of space.
It is, indeed, a large system, but if you want to save some money on bills, it is not necessary to build a system that provides all the energy you use. You can remain connected to the electricity grid, and build a system that supplies 30%, 40% or 50% of the energy you need, depending on your budget and available roof space.
