Step by Step Solar Energy Classes

Solar power systems for home come in a wide variety of types and sizes.? One of the first things you’ll need to know is exactly how you’ll be using your free energy.? The PV cells of a solar array absorb the sun’s ultraviolet rays and convert that energy into electric current… but that doesn’t mean you can use it right away.? The ‘juice’ created by the photovoltaic process is direct current (DC) and needs to be changed to alternating current (AC) before it can be used for your household electric needs.? This requires the use of an inverter.? There are some uses for DC current within the household, but most solar power in homes consists of electricity that’s been already transformed into a more standard usable form.

The next thing to consider is how you’ll be gathering this free, clean, renewable energy from the sun!? When most people think of home solar heating panels they think of those great big monstrosities that used to clutter rooftops back in the 70’s and 80’s.? Those ugly eyesores did little to promote the industry, and if anything they hurt the image of solar energy for decades to come.? Luckily in today’s world, advances in PV cell technology have made it so that you can harness the sun’s rays in a multitude of new ways.?

Rooftop solar panels installation is much simpler, easier, and a LOT more attractive these days!? Panels are smaller and better looking, and they can be mounted flush to the roofline.? Solar shingles are another way to go… you can build entire home photovoltaic systems that look the same as asphalt shingles or ceramic glazed roofing.? By tiling the top of your home with thousands of these tiny cells, you can harness free green energy year-round.? These systems go up easily with just a few solar panel installation classes, and in a few days or even hours you can begin lowering your electric bills while making the planet a cleaner place to live.

Solar heaters for pools are another popular do it yourself project.? You can install a diy solar pool heater in just a matter of hours, saving you hundreds of dollars over the summer in pool heating costs.? Either the sun warms water in an insulated tank, or a vacuum tube system is utilized to make the most of the day’s UV rays.? Water tanks can also be used in the home – for showers, dishwashers, washing machines, or anywhere hot water is required.

You can even take solar energy classes that will instruct you on the guidelines of step by step solar system setup.? From determining the angle of installation to drilling the struts that will support the array, one of the best ways to learn is through watching home solar panel kit videos.? The visuals and knowledge obtained by learning from these videos will give you the confidence to begin solar panels installation on any scale project, small or large.?? You don’t have to have previous experience with any type of green energy – the instructions are all that you need.

And when it comes to installation, usually only a few small tools are required: a laser level, a chalkline, a drill and a socket set.? In most cases connectors will snap together, but you may also need a soldering gun.? The hardware that comes with a home solar power kit is designed to attach to the backs of your PV panels and then be bolted or clamped right to the mounting struts.? In many cases these mounts will be adjustable so you can tilt them toward the sun no matter which month it is.? This allows you to maximize your solar exposure as the sun changes position (relative to your roof) throughout the year.

The Cost Of Solar Energy

Solar energy is a natural source of energy that comes directly from the sun. When solar energy hits the earth it spreads over the earth’s surface and provides warmth evenly. If you could capture the sun’s rays into a particular area for a long period of time it would provide enough warmth for nighttime or on cloudy days. Learning where to find solar energy can help you to get started today. Solar energy does not cost anything because it comes from the sun. The source that you choose may cost some but in the long run it should be your only expense, unlike gas or oil heaters that you continue to pay for monthly in order to have power or gas heat in your home. Solar power can provide heating, cooling and ventilation.

If you want to make your own solar power to capture the energy for heating its easy to do if you can find a solar collector, which is anything that attracts the heat from the sun in a concentrated amount, such as glass or clear plastic. Getting into your car that has sat out in the hot sun all day long can be extremely hot and you have to roll down your windows to cool it off inside. That is because the glass has attracted the sun and the objects in your car, including your seats, have trapped the heat not allowing it to escape. When you roll your windows down you are allowing the heat to escape causing your car to cool down. The same thing is true about greenhouses. The glass or clear plastic can attract the sun and not allow it to escape causing the greenhouse to maintain the heat for the plants to grow effectively.

In order to heat your home using solar energy, you need to know the information on a passive and an active home. These two types of solar homes offer the homeowner options to choose from and your cost of heating may be down. Solar energy does not only heat your home but it also heats your water and if you use solar energy lights it can light your home at night.

Passive homes do not use any equipment to heat the home. Passive homes use windows that are made to allow the maximum amount of sunlight into your home. The sunlight is controlled by keeping the doors closed in the hottest part of the day not allowing any heat to escape. At night thick curtains may be used on these windows so that the warmth stays inside during the night. This allows the sun to naturally heat your home without any help.

Active homes do use equipment to help circulate the heat in the home. Some of the equipment that may be used includes pumps, blowers and an alternative heating source in case the sunlight was not enough during the daytime. In order to heat the home with sunlight these homes use special boxes on the outside that attract the sunrays to it. They are made from a dark colored metal to help attract the sun more. The water or air that is carried in the pipes and ductwork is heated by this glass box that has captured the sunlight. Then the heated water or air is then carried to the rest of the home.

In the long run, solar energy helps to heat the home naturally and without depending on a company to supply it for you. Solar energy can be found anywhere the sun is.

Solar Energy: Technical Facts

Following are some of the basic technical facts about solar energy.

A photovoltaic module or solar panel is made up of about 40 photovoltaic cells. “Photovoltaic module” and “photovoltaic cell” are the “technical terms” for “solar panel” and “solar cell.” When a photovoltaic module is used to charge batteries it is commonly referred to as a “solar battery charger.” Several photovoltaic modules or panels arranged alongside each other are referred to as a “photovoltaic array” or a “solar array.” The usual setup for a system in the home consists of an array consisting of ten to twelve panels or photovoltaic modules. The color of the panels varies, depending on what material is used to make the cells inside the panel. Energy from the sun can be collected by hybrid chargers and used to recharge batteries, or to recharge cell phones and other gadgets directly.

Environmental Facts:

All life on Earth is dependent upon solar energy. In fact, without it, there would be no life at all. Even the lowest life forms on Earth, such as plankton and microbes, need energy in the form of sunlight in order to survive. Solar power is completely environmental friendly, producing absolutely no carbon emissions or other harmful byproducts, whatsoever. It can be used successfully and cost-effectively in just about any location on the planet. You do not need to live in a tropical or desert climate in order to benefit from its use. It has been used successfully in many cold climates, and even in the polar regions. Every area of the United States of America receives enough sunlight to benefit from and make use of solar technology. Currently, the cheapest and most effective way of using solar power in your home is through the use of solar hot water heating systems. In fact, these systems have been commercially available in the United States for over a 100 years. The sun’s energy can be used for heating homes effectively in cold climates, as well as in warm climates. In fact, this form of heating has been in use many cold-climate northern European countries for several decades now. Solar energy technology has advanced far enough that it can be a viable and cost-effective replacement for regular grid-electricity. It is rapidly increasing in popularity – so much so that the demand for solar-powered gadgets is currently greater than the supply.

There is no shortage of energy on Earth and no need to use damaging fossil fuels. It is simply a matter of advancing and utilizing alternative energy technologies for a cleaner future.

This last choice provides you with the most amount of sunlight to collect.? No matter which area you live in, solar energy can help produce electricity for your home or office.? Energy is stored so that even on cloudy or hazy days you can benefit from solar energy.? Some areas can allow you to install a solar system that produces so much power that you could even go off-grid while selling back an overabundance of energy to the power company. Local governments offer incentive plans for going green.?

What is solar energy?? It is the universal gift to our planet that will help allow us to dismiss our dependence on fossil fuels.? It is the universal gift that allows life to thrive and continue until the Sun itself burns out. Much can be done for your home, office and planet if you go this route and produce power from our guardian angel, the Sun.

List of Everyday Devices That Use Solar Energy

Solar power is an interesting technology. People have been using products with solar power panels since they were children and don’t even realize it. Remember those tiny little calculators with the black strip. Whenever you held your finger over it, the screen would disappear. That was solar energy.

Those calculators are one of the most popular items that use solar power. But, these days there are so many more products that are using the growing technology. Solar panel works well because it’s a renewable energy, which means it will replenish itself after being used. The sun comes out everyday and people never have to worry about their solar panels not working. Some of the bigger products that use solar energy are steam generators. People use them to heat and light their homes. Companies use them to run machines in their plants. However, there are smaller and practical uses to solar energy as well.

Campers and hikers can benefit from solar energy and people who need emergency items. Companies are producing radios, lights and battery chargers that use just solar power. What is so great about these products is that there are many different types you can buy. There are some radios that come with AM/FM with a built-in flashlight. Others have AM/FM/VHF/TV. Imagine all these products and all they need is a little light to get started.

There are many companies that make solar powered flashlights and lanterns. These work great in emergency situations when you have no batteries or any other resource to light your flashlight. The flashlight will be charged during sunlight hours and then be used at night. In case you need the flashlight at night, there are some lights that have cranks to get them started. If you have a solar powered battery charger, you now have the batteries for your flashlight.

Other products include a solar power cooker. You can cook in the outdoors and never have to worry about propane tanks again. There are small portable backup solar generators as well. Solar power has so many uses that it’s hard to believe there aren’t more tools with it. Some companies are selling solar volt testers and vehicle cigarette lighters. These can also be used in conjunction with the solar battery chargers. The battery chargers usually come in 12-volt or D battery settings. The 12-volt battery can be charged to use coffee makers, stoves, beverage heaters, mini coolers, lanterns, flashlights, hair dryers, electric razors, heating blankets and so much more.

As research companies find new ways to use solar power, start looking for it on more gadgets. Currently, there are people testing solar-powered cars and boats. There have been test models of these made but none for practical use. Right now it takes too many solar panels to get the vehicle moving and getting a person inside of it. Solar power is a path into the future. As new alternative energy is discovered, try to do your part in helping the environment with these great gadgets.

Electricity Saver 101: All About Residential Solar Energy

Not only gas prices are soaring nowadays; electricity bills are, too. In some countries, a lot of people have started utilizing electricity sources that bring about more savings. The most common are the so called solar panels, which are able to make use of solar power to produce electricity. Electricity that comes out of solar panels is more popularly known as residential solar energy that can help you save on electricity bills. How the said type of energy is produced is something that needs to be answered.

Panels that bring about solar power actually work in a simple manner: their job is to ensure that the sun’s light is transformed into usable energy that will give their users the electricity they need. This is done through silicon atoms that bond with each other in order to facilitate electron-sharing and therefore help in giving off electricity.

Part of the process of producing electricity through panels that produce solar power is combining silicon atoms with the photons that are produced by the sunlight. Once silicon atoms, their electrons, and the photons are mixed together, electricity is generated. Take note however that for a big amount of electricity to be produced, a lot of solar energy is also needed, which equates to the fact that more solar cells are also needed.

Some people may think that solar power producing panels may be hard to obtain, let alone placed in their homes. The truth, however, is that there are now various manufacturers that offer solar panel kits that come with easy installation and are definitely easy to use. The said kits also come with tools, better known as inverters that enable the production of power for home use.

If you have the desire to purchase solar panel kits, keep in mind that to get maximum benefits and to ensure that the output works properly, have those kits installed by the experts. Though it may be true that those kits are extremely easy to install, there are still some factors that may affect the performance of your finished product such as the roof angle of your residence, the directions the solar panel’s trackers face, and many more.

Finding out everything about how solar energy may be produced and how solar panels may be utilized are usually some ways of motivating people to consider the use of solar power in their homes, offices, shops, etc. Electricity produced from panels that emit usable energy may also be used in street lights, lighthouses, and even in traffic signs. Through the use of solar power, the process of energy conservation is practiced. Take note too that the electricity a user gets from solar panels may be described as reliable and very simple to maintain.

In our world that is bombarded with the rising prices of utilities, specifically high electricity bills, the only way to save a significant amount of money is to look for other sources of energy. Residential solar energy has a lot of benefits that we can enjoy for as long as we learn the right ways to obtain it.

Understanding of Solar Energy Usage (chapter 1)

An average person, being asked about solar energy usage, will describe solar panels (photovoltaic converters), what can be observed at many households and business properties these days. However, to truly imagine benefits of green solar energy, we should first understand its nature and the ways how solar energy can be produced and used.? There are two major parts of solar energy reaching Earth surface: infrared radiation and light. Other significant part of solar radiated energy is represented by UV, X-rays and high energy particles. Those are, fortunately, being cut off by Earth ionosphere and atmosphere, and not reaching the Earth surface in considerable amounts.

????

???? Infrared radiation is generally being converted into heat by passive converters (heaters), and used mainly for hot water production. There are many households, especially in California, Florida and other sunny regions, where electric water heaters are being rarely used even during winter period, due to implementation of Sun heat collectors. Other way to benefit from green solar energy is just do not waste it. Another words, use the building design and materials well insulating interior from exterior. We can lower our energy needs and build an energy efficient structure by integrating south facing windows and materials that retain heat, like bricks and wall panels.

?

???? The most well known solar energy usage is generation of electricity using semi-conductor, converting energy of sunlight into the energy of charged particles, used further to produce electric current. (The above sentence looks complex. However, it has been borrowed from grade 7 school physics book). One square meter of solar panel is capable to produce approx. 100 Watt of power, depending of sunlight conditions. Electric power is being accumulated in the batteries, to be used during night hours. Efficiency of solar panels is frankly not very high: 10-22% depending on manufacturer and sunlight conditions. This fact leads to quite a large surface area, required to produce substantial amount of electricity. Solar power setup requires an electronic charge controller, batteries and power inverter to produce an alternative current, used to power majority of home appliances.

Some Facts about Solar Energy

Solar energy is for everyone simply because the sun shines in every corner of the planet. In fact, the history of solar energy can be traced back to the Greeks that were then passed on to the Romans which marked the first people to ever use the passive solar design.

Passive solar design is a way to warm the home based on the dwelling?s design. They may not have had glass windows back then but their architecture made it possible for the people to use the sun?s rays to light and heat indoor spaces. As a result, there was no need to burn food that often which was in short supply.

In 1861, Auguste Mouchout invented the first active solar motor. Unfortunately, its expensive price made it impossible to produce commercially. Less than 20 years later, Charles Fritts invented solar cells which will later on be used to power homes, heaters, satellites and other devices today.

Since what he invented was very primitive, other people experimented on solar energy. One such person was Albert Einstein who won the Nobel Prize for physics in his research on the photoelectric effect which is a phenomenon associated with the generation of electricity through solar cells.

In 1953, Bell Laboratories? which we know today as AT&T labs developed the first silicon solar cell capable of generating a measurable electric current. Three years later, solar cells ran $300 per watt. With the Cold War and the Space Race on, this was used to power satellites and crafts.

But the biggest event in the development of sola energy occurred during the oil crisis of 1973. This prompted the US government to invest heavily in the solar electric cell that was developed by Bell Laboratories 20 years ago.?

By the 1990?s, research towards solar energy came to a standstill as the price of oil dropped in the world market. Funds were diverted elsewhere and the United States which was probably the leader in this form of alternative energy was soon surpassed by other nations mainly Germany and Japan.

In 2002 for example, Japan had installed 25,000 solar panels on rooftops. Because of that, the price of solar panels went down as the demand for it was on the rise. To date, solar energy is growing at a modest 30% per year.

Although there have been improvements in solar energy, its fundamentals are still the same. The sun?s rays are collected and then converted into electricity. Aside from powering homes or office buildings, the technology has been used to power aircraft, cars and boats.

Unfortunately, none of these have been made available yet for public use. We still rely heavily on oil for electricity, gasoline for our cars, fuel for planes and ships.

In fact, the US is one of the biggest oil users in the world. To prove a point, the department of Defense consumes 395,000 barrels per day because of the wars being fought right now in Afghanistan and Iraq which is almost the fuel consumption of an entire country like Greece.?

This has to change because our oil reserves are almost depleted and many experts believe that global supply for these non-renewable resources will be gone before the end of the century. We have to do our share to push for renewable energy and one of them happens to be solar energy.
