The basic answer is specific materials placed in direct sunlight will convert the light to electricity which can be used to power electronic devices. But it’s a little more complicated.

Today’s production of solar panels consists of using supremely pure silicone semi-conductor materials. Electrons are discharged from silicon semi-conductors when placed in sun light. This creates a potential as well as flow of electricity. A solar panel is also called a ‘direct energy conversion device’ since all of these effects are taking place on an atomic level minus any moving parts.

PV panels used to be only available in space race technology. Satellites and space stations used them for their reliable and continuous conversion of solar power. The sun’s radiation is 50% stronger in outer space giving solar energy an advantage in that environment. Solar energy devices have been used extensively in the space program.

People looking to live a good distance from the power grid, more than a mile, are more likely to use solar energy. Power transmission cables cost way more than installing a photovoltaic power array. If you are a significant distance from an electrical grid then it’s a good idea to consider solar energy for your power source.

To generate cost effective solar power, a sunny location is neccessary. Beam radiation is the most effective since it’s the strongest. Most of Western America qualifies…those states are good candidates for the use of solar energy, but northern climates and coastal states are usually quite cloud-laden and sadly, not worthy of 100% solar-reliance. You can search online for “solar insolation rates” to determine if your area is suitable for a solar energy system.

Solar panels can be set-up to meet your specific needs. The most common DC systems are rated 12 volt, 24 volt, and 48 volt. Solar panels have efficiencies in the range of 12-14% and can have a life expectancy of over 20 years.

If I was a betting man, I’d bet you are already using solar power. It is in your fuel, your food, and in some form or another almost everything you do. In more practical terms, though, we are talking about heat and electricity. Why should we use solar energy systems to power our homes?

The answer is that solar energy is reliable and free. From the early morning dawn to the late evening set, the Sun will shine each and every day. Solar energy may be the single most consistent thing there is on our planet.

For now the government isn’t taxing it and there are no greenhouse gas emissions. And solar energy needs no refinement, it’s ready to go. Rays of sunshine from above, perhaps nothing more perfect than pure solar power.

So what if your photovoltaic system is only 12% efficient, or your solar collectors absorb only 70% of the available heat? The reality is, your power source is free! No more utility bills, gas stations, and no more power outages. When your solar power system is finally in service there are no more continuing fuel costs. All that could take you down would be a volcanic cloud or weeks of unstoppable rain.

The difficulties in using solar energy are with selecting the right application and the right equipment. How much does a solar energy system cost and how difficult is it to integrate? How simple or elaborate should it be? In my location, is solar energy right for me? Here are some straight answers to help your case.

If you have a sunny climate with lots of solar energy, then put it to use. You will save money long term and do so in an environmentally safe way. We would estimate that at least 50% of the United States could be using solar energy in some way.

If your home is overcast and rainy most of the time then a solar power system probably won’t work well for you. Coastal climates and winters in the north are difficult for this. But this does not mean you should not investigate, there may still be some opportunity.

When it comes to making heat and hot water with solar energy – absolutely. We call this passive solar heating. These are cost effective systems that can be incorporated directly into your business or home. A lot of designs for passive solar heating are cheap and simple.

When it comes to making electricity from solar energy, the answer will depend on many things. All in, the furnaces and combustion engines of the local power company are just some times hard to beat.

If you are using tons of electricity in your home or your business then solar energy may be difficult to justify. This is where local Utilities are good, they can kick out the juice for all the high power users and the heavy duty industries. But if you are simple in life and efficient in how you use energy, then the up-front cost of solar power can pay off over time. It could be as little as 5 years depending on the electrical rate of your local utility.

If you are miles from an electrical supply then solar power can save you a bunch of money. You can save money by avoiding expensive transmission cables routed to your property.

If you are interested in an emergency reserve of energy, then this also is a good use for solar energy. With just a few solar panels you can charge a large bank of batteries. So when you get those destructive storms and environmental disasters, just kick in the emergency reserve and ride it through.

Whatever your specific purpose, the reasons for using solar energy are many. Be it an emergency back up, a money saver, or just to reduce pollution, installing a solar energy system is a beneficial experience.

If you reside in a region that experiences long, harsh winters you may be wondering if solar panels would work on your home. After all, days or weeks of dark skies, snow flurries or monsoon rains hardly seem compatible with a technology that depends on the sun to run it.

However, there has been a lot of innovation and improvement in solar panel technology during the last 10 years. Now solar technology is far enough along that solar panels can easily produce electricity even during inclement weather conditions.

Solar Panels – Will They Work During Winter? Click The Link!

Off grid systems will include a set of storage batteries (similar to a car battery) that are to hold any excess power that your solar panels produce during the daytime. If your battery storage system is correctly designed for your region, it will include enough of these batteries to store power for the number of cloudy days that are typical for your geographical area.  

If your system is tied to the grid (connected to the local electric company) it won’t use storage batteries. After the sun goes down or if there are several days of inclement weather blocking the sun, your system will automatically use electricity from the local power company. You’ll still be reaping the benefit of reduced power costs because on sunny days your electricity will be generated by your own solar panels.

Maintenance and More on Domestic Solar Panels

Some power companies may even allow you to sell electricity back to them.   This is yet another way solar panels can prove cost effective. The way this is set up is that unused electricity generated by your solar panels goes back into the grid and you received credit for it on your bill.  That way, even if you have to use electricity from the grid during the night or during cloudy days, any unused energy that your solar panels were able to produce will still be reducing your overall energy costs.

Installing a solar electric system to your house is a big decision and investment. And if you are considering it, you may also wonder if it will add value to your home. To help you answer that question, here are several factors to take into consideration.

The Saving of Solar Panels

First, how is the awareness level in your community when it comes to the benefits and merits of using solar power? If there is a lot of interest and participation in the “green” movement, there’s a good possibility that buyers will view the solar energy system as an asset and will be willing to pay more. However, if your area has little eco-friendly involvement, for example not many people recycle or show concern for environmental issues, buyers may be indifferent to the money and work that went into installing your solar panels.

But even where there is utter apathy for green living, most people can appreciate the idea of saving money.  If you can show a record of your energy savings over a period of time, the potential buyer will have proof that the solar power system will be a benefit.  With utility bills often running into several hundred dollars a month for some families, savings on electricity becomes important.

The Solar Power Option Away From The Grid

But what if you’ve only had your solar panel system for a short time? How can you prove energy savings? Contact your utilities company and ask for a statistical projection of cost reduction over time. You could also obtain information from the company that installed your solar panels. The bigger companies often have marketing departments that collect this type of data to demonstrate  how installing solar panels can help reduce energy costs.

Something else to consider is how popular solar power systems are in your housing market.   If solar panels are common, your real estate agent will be able to give you actual statistical data that shows the difference in selling price between houses with solar panels and those using only public utility electric service. If you can get your hands on this kind of data, you will have some great proof to present to a potential buyer.

Here’s A Method To Economise On Energy Costs

We hear about solar energy in the news almost every day.  But have you ever wondered if installing solar panels on your home would be a good decision for your family?   Here are some great reasons to consider it.

Watch How The Solar Panel is Put Together

The economic climate is again favorable for those who want to use solar energy at home.  There are now federal tax credits in place (or soon to be) that can reduce the cost of installing a residential solar energy system by as much as thirty percent. And don’t forget to check into your state and city incentives, too. The list of states and cities that are offering tax credit and other incentives to assist people in converting to solar energy is continuing to grow.

There is also the immediate cost savings you will see in lower monthly utility bills. Since your solar panels will be powering your appliances during the day, you will be seeing a savings in electricity usage. And if your local utility company offers net metering, your electric bill could be reduced to zero.  Net metering allows you to sell back any excess electricity that your solar panels generate to the electric company for a credit to your account.  So when your solar panels generate a surplus during the day, the electricity used from the grid at night could end up being free.

This Shows You How The Solar Power System Functions

Solar energy is also beneficial for the environment.  It is produced on site where it is used, so there are no fuel transportation costs or emissions, and no plant maintenance costs.  Using solar energy can help prevent global warming.  Solar power does not produce pollution by burning oil or coal, or nuclear waste that will contaminate the planet for many years to come.  And last but not least, it is a great way to protect yourself and your family against the future energy price hikes that experts are forecasting.

The future of this planet is of the utmost concern to many environmentalists. Solar energy now plays a key part of the methods being developed to curb the greenhouse effect around the world. You may think that your power company should offer the solutions to energy shortages. Get the facts! It behoves us all to seek out the most economical route to installing solar power. Irrespective of the method that you decide upon, you will need to do some research before you embark on your project in order to avoid costly mistakes later on.

The Most Economical System of Solar Power Installation

Global warming is in the news and most Americans are looking for ways to reduce their carbon footprint on planet Earth. Home solar panel installation can make a huge different in the size of your carbon footprint. Utility companies in the United States use fossil fuels like coal and oil to produce much of their electricity. Home solar panel installation reduces your dependance on the utility companies and helps to reduce their use of fossil fuels.

Greenhouse Gases

If you depend on the power grid for your electricity, at least some of the power you are using is derived from burning fossil fuels. Burning fossil fuels creates greenhouse gases and contributes to global warming. Home solar panel installation reduces your dependance on the power grid and fossil fuels and reduces your personal impact on the environment. Using a clean, renewable energy resource reduces your carbon footprint. Some people are able to live off the power grid by using solar panels to supply all of their electricity. Solar panels can save you money on electricity.

What’s In It For You

The cost of fossil fuels is rising as the supply decreases. This means that utility companies are paying more to make electricity and passing that cost along to you all because of Science Global Warming. The cost of solar panels is dropping as the technology improves. Home solar panel installation will save you money now and even more money in the future as energy costs continue to rise. Homeowners who live in urban areas can be subject to power outages due to heavy usage.

Given that fossil fuel supplies are beginning to run low and environmentalists are exerting pressure, the cost of grid electricity is only going to increase in the future. Who knows how much it will cost to live entirely on the grid ten years from now. One thing is for sure, the cost of living on the grid will surpass the expense of home solar panel installation very soon if current tendencies are any indication.

Other Incentives

There are many financial incentives for home solar panel installation. You may be eligible for state and federal tax rebates if you install solar panels. You may also be able to apply for a government sponsored home improvement loan at very low interest rates. In the United States, the government has recognized our need to reduce our dependance on fossil fuels. Our economy has become too tied up in imported fossil fuels and we have to find domestic alternatives. The financial incentives offered by the government can make alternative energy sources like solar panels very attractive. Being independent of the power grid means no more worrying about high bills or scheduled power failures. It could earn you the envy of all your neighbors.

As evidence continues to indicate that Earth’s fossil fuels sources are not going to last forever, governments around the world have been looking to renewable resources as an alternative. Sunlight harnessed by residential solar power panels can provide a very energy-efficient and cost-effective alternative.

Residential solar power panel kits are available from both online and “brick and mortar” retailers that are easy to assemble and can be directed to power electrical and heating appliances. There are several advantages to using a residential solar power panels and more and more people are thinking of exploring this alternative energy source for their own personal uses inside the home.

The Advantages and Disadvantages of Residential Solar Power Panels

When the sun shines on a residential solar power panel, it’s power is stored and can be used to power a house. Using this renewable energy source to supply power to a home offers enormous benefits to homeowners. Solar power is received for free and is readily available in areas where there is enough sunlight to power these solar panels.

The money you save in powering your home is the most obvious benefits to residential solar power panels. Solar power is free and all you need to consider is the initial cost of the solar panels and installation, after which you can get an endless supply of electrical energy to power a small appliance or gadget. Advances in green technology means that the cost of residential solar power panels has come down, opening the way for the average homeowner to take advantage of this alternative energy source.

Homeowners can now afford to purchase multiple solar panel systems to be installed in their homes to generate enough electrical energy to power everything that requires electrical power. This energy is free and powerful, sometimes powerful enough to send energy back to the electric companies. Some homeowners have gone all the way and run their home entirely on solar power all year round.

The residential solar power panel system must be positioned properly so as to collect the sunlight. People who live in areas where adequate sunlight is not available won’t be able to use the solar panels. Depending on the number of panels required to power a home, the panels may take up a lot of space. Thankfully, advances in green technology means that solar panels are getting smaller, taking up less space and yet producing just as much, if not more power than they used to.

Despite the disadvantages, the advantages of using solar power panels far outweigh them and the use of these solar panels will continue to be more popular as a viable alternative source of energy for the home and eventually the industries.

Every year the sun sends down to the earth 170 Petawatts of energy in the form of light and heat and about 80 Petawatts eventually reach the ground. To get a better idea of what this amount of energy relates to, 40 Petawatts (80,000 trillion watts) or half a year’s worth is equal to all of the fossil fuels that we can ever extract from the earth. It’s free, non-polluting, and contributes 0% to global warming. So if you live where the sun shines a lot you are in an ideal position to build your own solar cell panels and make drastic cuts to your electric charges while simultaneously doing your part to protect the environment for future generations.

Since we are using up fossil fuel sources more rapidly than new ones can be discovered, it is only reasonable to start turning to one of the most abundant energy resources at hand that is free—solar power. It is a renewable resource that has not yet been fully tapped by a lot of countries which gives it almost unlimited potential in the future. You can capture this energy when you construct a solar cell that you locate either on your roof or near your house angled so as to catch as many sunshine as possible and transform it into electricity. You will need 10 or 12 panels to capture at least a kilowatt of power.

The biggest problem in the use of solar power is that it can only create power during daylight hours. The answer to this is to put an auxiliary system in place that will store the energy and then kick-in when the sun is not available. The most common supplementary system is comprised of deep cycle batteries that can supply power after the sun goes down or when a brownout happens to occur.

Quite a few individuals hesitate to implement a solar alternative energy solution for their home fearing that they are too expensive and unwieldy. They do carry a hefty price tag if you opt for professional installation but it may come as a surprise to you as to how cheap and uncomplicated it is to put up an alternative solar panel solution to that high monthly electric bill. If you live where there is a lot of sunshine and there aren’t trees or nearby mountains to block out the light, then you need to look into making your own solar panels and saying goodbye to high electric bills.

In California it is customarily acknowledged that converting your home to “green energy” is equal to eliminating two autos from the highway. Solar cell panels have more advantages than just being eco-friendly. They require very little maintenance which saves you time and money. Also, solar systems give you a return on investment very soon, thus making the systems free after some time. Solar energy is a smart alternative energy option and you can enjoy saving money while getting the satisfaction of building your own solar cell array.
