If you are planning to install a solar energy system right at your home and would like to know how much it would cost, there are 3 things you need to consider:

1. the cost depends on how much energy your household requires. More energy you require means more solar panels and higher cost of installation. The good thing is, the technology to harness the power of the sun is relatively cheaper than it was several years ago. 
2. the government is offering a rebate to those who will switch to alternative form of energy. That means, the government will shoulder a portion of the total cost of the system.
3. you can get tax credits when you switch to solar energy system. The amount of tax rebate depends from state to state but the range can go from $1000 to $2000. 

All these affect the overall cost of your installation.

A photovoltaic system can cost roughly at $8000 to $10000 per 1kW system. This equates to $8 to $10 per Watt. An average American household with 3 bedrooms requires at least 1.5kW to as much as 3kW. Thus, installation can cost from $14000 to $30000, before rebates and tax credits.

Government rebate varies from state to state. As a reference, an average California household that requires 1.5kW system can get as much as $4200 rebate (1.5kW= 1500 watts x $2.80 per watt = $4200).

A household that requires 3kW system can get as much as $8400 (3kW= 3000 watts x $2.80 per watt = $8400).

Before, tax credit goes as much as 30% but it is lowered to 7.5% of system cost after rebate.

So an average household with 1.5kW system can get $735 ($14000 - $4200 x 7.5% = $735) worth of tax credit while the 3kW system can get $1620 ($30000 - $8400 x 7.5% = $1620) worth of tax credit.

Example A: 1.5kW system

Cost of solar electric system: $14000
Less rebate: $4200
Less tax credit: $735

Cost of the system after rebate and tax credit: $9065

Example B: 3kW system

Cost of solar electric system: $30000
Less rebate: $8400
Less tax credit: $1620

Cost of the system after rebate and tax credit: $19980

Again, these are rough estimates just to give you an idea of the cost of installing solar energy system. They do not represent real figures.

Solar power can be generated in different ways. It is important that you learn more about the available types and the devices that can generate energy efficiently. There are already solar power generators available. You may order these online or via your local store. You can also choose to build your own generator. Find out more about solar generation by talking to the experts as well as asking others who have already tried building their own.

The Basics

Solar energy is very promising because it is renewable, which means that you can continue getting the power you need nonstop. The sun provides a large amount of energy that artificial units cannot sufficiently give. The small part of the power stems through to the earth in the form of sunlight. The rays that deliver the energy of the sun give both heat and power that can effectively be gathered and changed to other types of energy, such as electricity. Solar steam generators use solar power generation use the power of the sun to heat water and create steam to let electrical turbines work.

Another popular method of solar power generation is through the use of photovoltaic devices. The devices are made to use photovoltaic cells or solar cells to transform solar energy into DC electricity. There are plenty of ways to collect solar energy such as through parabolic troughs, solar panels, solar dishes and solar power towers that have reflecting mirrors. A number of solar collectors are categorized as either concentrating or non-concentrating.

Concentrating and Non-Concentrating

The concentrating gatherers use panels that are angled the right way to absorb the prime point of the direct rays of the sun. Non-concentrating gatherers are ideal for regions that have lower amounts of direct sunlight and absorb the energy rays of the sun from direct and various reflecting angles. Solar power generation is under heavy research for ideal materials and processes of collecting the sun's energy and utilizing solar generators to create both heat and electricity.

The Applications

Solar power can give several applications for businesses, homeowners and companies. Present solar power plants are not yet very rampant, but experts see a growing population as the technology and supply for energy supply that is both clean and safe becomes more available. Energy systems are now widely available to help utility companies provide power to offices and homes. The solar power delivered to utility companies and used by people for various electrical applications is used all over the globe. Solar panels can be used to heat and power different electrical appliances in the house. Solar panels can also be used to convert sunlight into electricity to power heating systems, lights and air conditioning systems.

The Cost

The cost of a solar power generator will vary depending on the size, materials and applications where it will be used for. Big power plants will have to spend millions to get the desired effect. Small households can only pay a few hundred dollars for the right setup.

Everything You need to know about Solar Panels

Solar panel 3 (Photo credit: Photo Mojo Mike)

The solar panel is the most basic element of a solar power system. It primarily functions to gather sunlight during certain periods of the day to power different devices and structures. Depending on the size, solar panels can power anything from RVs to huge plants. It is also important that you understand how the panels work and where you can apply these so that you can get the most benefits. Here are some more details and info about the material.

What are Solar Panels?

Solar energy starts with the sun. Solar panels are also known as photovoltaics and are primarily used to convert light from the sun. These are made of energy particles called photons that are changed into electricity to power various electrical loads. Light from the sun is considered as a renewable energy resource that gives clean energy. Solar panels can be used for different applications like remote power systems for cabins, remote sensing, telecommunications equipment and to produce electricity for commercial and residential panel systems.

The History

The development of the solar energy began more than a century ago. During the early days, solar power was used mainly to produce steam for drive machinery. Henri Becquerel discovered the photovoltaic effect that allowed the conversion of solar electric energy. Becquerel's discovery triggered the invention of the first true solar cell by Charles Fritts in 1893, which was created by coating selenium sheets with a thin gold layer. The solar panel was then created afterwards.

Russel Ohl is an American inventor who used to work for Bell Laboratories. He patented the first silicon solar cell in the world in 1941. The first solar panel was produced by the same company in 1954 because of Ohl's creation. The new solar panels were used first in space satellites. During the 1970s, more people saw the use of solar panels through the newly designed calculators that can run easily under light.

At present solar panels and full solar panel systems are used to power different applications and structures. Aside from calculators, solar panels are now used to give power to homes, commercial buildings and other huge structures.

Letting the Solar Panels Work

Solar panels can gather clean renewable energy in sunlight form that will be converted into electricity. The average home has adequate roof area to let solar panels gather enough sun to be converted into DC current or AC current. Solar panel arrays can be sized to meet big requirements. The AC current can power loads in the house and other commercial buildings. It is important to consider the part of the house, as well as the right angle of the sun so that the solar panels can gather the most light over more hours of the day for optimum results.

You can choose to build your own solar panels or just order a pre-made one online. There are also a number of stores that offer solar panels, depending on the use you need. You can hire some experts to help you determine the right part of the house or structure where you need it installed. You should also talk to other solar panel owners to help you maximize the benefits.

Solar Power For Your Home

Solar energy is described as power coming from sunlight. It is a very economical way of getting energy needed for different household tools and devices such as lighting, power tools, appliances and other gadgets. You can save more in the next few decades by investing in solar power. You have to know the different types of setups and the things you need to consider before you choose to purchase and install. Here are some proven tips.

Getting Electricity

Solar panels are primarily installed on a flat surface such as the roof of the house. This ensures that the panels get and absorb enough sunlight to power the different items inside the home. As soon as the solar panels are activated, these will absorb the rays of the sun. The panels are made of semi-conductors like silicone.

Electrons are then released from the atoms to produce electricity. The photovoltaic effect is achieved when light is converted into electricity. You can then have direct current electricity. When the power enters an inverter, you can get 120 volt AC conversion, the same electricity required to power the house. The connection will be to the utility panel so that appliances and lights will work the same way when the switch is turned on.

On Storage

If the house is not using a lot of electricity from the solar energy created, the excess energy can be stored in a battery. When the sun is out, during night time or in the case of a power shortage or outage, the battery can be used to power different items in the home. If the battery becomes full, the extra electricity will be exported to the utility grid if the system is linked to it. Once the solar energy runs out, electricity coming from the utility will take over. The flow of solar energy electricity is measured via a utility meter that spins forward and backward.

The meter will move backward if more energy is produced than needed and the meter will move forward when extra power is required from the utility company. The two are only even when additional energy is paid for from the utility company. The surplus will go straight back to net metering. The smaller version can power a water heater in the house. Homeowners can also get the same effect by simply converting sunlight into heat.

Environmental Friendliness

The good thing about solar energy installed for homes is that the system is very efficient and environmentally friendly. You can let your kids go to different areas of the house without having to worry about pollution and poisoning. Getting a system also means that you are saving the surroundings from stress and other pollutants in the years to come. You can get a cooler and cleaner environment by investing in a solar power system. You may choose to get a DIY kit or just have a professional install the system. Make sure that you properly position the panels to get the most sunlight and get maximum conversion.

Solar energy is fast becoming one of the more promising alternative forms of energy sources that is out in the energy industry today. The main reason for this is probably due to the fact that its main source of energy, which is the sun, is able to provide over 10,000 times more than the energy that our planet is able to produce. This helps show people that solar energy is one of the best alternative energy sources for the future. However, don’t simply take my word for it. Instead, check these different solar energy figures and statistics and see for yourself if whether solar energy is indeed everything that people are claiming it to be.

Is Solar Energy Systems Financially Viable?

One of the main things that people look at when it comes to alternative sources of energy is whether it is financially viable or not. Getting a solar energy system for your home or work place these days would actually help you save some money on the total cost of your utility bills annually. However, this particular benefit is not necessarily immediate, as there are some other costs that you need to consider. Nonetheless, using solar thermal systems would allow you to get back the total cost within 5 years of installation, and 15 years for photovoltaic panels, after which, you can then enjoy the benefits of cutting down the total cost for your energy consumption.

Does Solar Energy Reduce Cost Of Energy Consumption?

Studies have shown that using certain solar energy systems do reduce the total cost of energy consumption that your home or work place might incur. If done right, you can actually lower your annual utility bill by as much as 80%, which is very significant, especially if you are trying to find ways to save some money.

Also, there are certain programs that allow solar energy systems user to sell back energy or electricity that they were not able to consume to the utility provider, giving you more ways to save money.

Do Sunny Areas Have More Solar Energy Systems?

Although the ideal location to place these solar energy power plants to harness sunlight would be in locations that have an ideally hot climate, some places which does not have that hot of a climate are known to have more solar panels than those which have hot climates. Denmark and Holland, and most of the northern European country, claims that they have more solar panels than the United Kingdom, indicating that you don’t necessarily have to have a hot climate in order to enjoy the benefits of solar energy.

How Much Area Does Solar Power Plants Need?

Most, if not all, solar power plants require a certain stretch of land area in order to house all the solar panels that these power plants need to have in order to properly harness and collect sunlight and solar energy. Depending on the size of the power plant and the solar energy output needed, each solar power plant land area would vary, from 250,000 square meters of solar panels in the United Kingdom, to the 93 million square meters of solar panel in China.

Is Solar Power a good Business?

Català: Planta de concentració fotovoltaica a Torregrossa (Lleida) (Photo credit: Wikipedia)

Solar power is quickly gaining popularity all over the globe. It is growing at a rate of 2% per year, and if the figures continue to grow, solar energy will be the preferred source of energy worldwide. Most modern nations are encouraging people to rely on this renewable resource so that they can save more and help conserve the environment. The trend can continue to provide benefits for decades to come if well-maintained. Here are some more tips and tricks.

About Location

First, you have to consider your current location. Are there a lot of clouds or does it rain or snow frequently? How much sunlight do you get per day? Some locations are very ideal for installing solar cell panels, while other people may do better with an electrical or battery source. Places that get around 4 to 6 hours of sunlight per day at least can do well with a solar energy system. Preferably, tropical and desert areas should start investing in a solar energy system to get the most benefits. Determine the angle of the sun to know which spots are most ideal for installation.

About Resource

Are there any available hardware stores that offer the needed parts for your solar energy system setup? Will ordering online be easy and convenient? Are there agencies or professionals who can offer reliable and quality services to install and maintain the solar cell panels. Are the materials affordable and of good quality? These are some questions you need to consider to get the best deals. Ordering online will depend on your location and the mode of transportation. If you think that setting up and maintaining the system will be difficult, it might be better to wait until the technology is more rampant in your area.

About Budget

Solar cell systems are generally costly in the beginning. Later on, you will realize that the costs will start to go down, since the energy stemming from the sun is free and available all the time. You should consider your budget by determining the area that needs to be covered with solar panels. Budget is vital so that you do not go overboard and overspend on things that you do not truly need. You should also consider the gadgets and devices that will be powered via solar means.

Longevity

A well-maintained solar energy system will last for 30 years if you keep it properly. Other setups may only last for a number of months or weeks at most if external conditions are very harsh or can damage the material easily. You can choose to create your own solar cells or just purchase from a source. The longevity of the setup will depend on the quality of the material, the use and applications. Price does not immediately equate to quality or longevity. You should know more about the available brands and check if there are any differences with regards to feature that will ultimately enhance the lifespan. Ask for recommendations from friends and others who have tried the setup.

Solar Power is it for you?

Solar-Powered Outhouse II (Photo credit: Ed Bacchus)

The advantages of solar energy continue to grow with more pros and experts learning more about the process and features. Of course, there are also a number of consequences especially for the person who does not study much about the devices. It is important that you weigh the potential of having your own setup. You should consider the things you need to power, your location, budget, etc. Here are some more details about the energy.

On Availability

The good thing about solar energy is that it can be used anytime or as long as the sun exists. You can get the power you need day in and day out. Solar power is a renewable resource which means that you do not have to pay any bill or keep replacing parts to get the results that you need. The disadvantage in terms of availability is that you cannot access the energy if there is no sunlight. You cannot rely on solar power at night or in places that tend to be very cloudy for several months. People living in tropical areas or desert regions can rely on solar panels. However, those who experience very long winter months may not get the best effects.

Things to Power

Nowadays, solar energy can power a variety of objects such as homes, offices, cars, small light fixtures, toys and calculators. You can now rely on the sun to help you minimize utility and electric bills. You can even see a number of vehicles now solely powered by the sun. The disadvantage to the approach is that the power may tend to fluctuate depending on the sunlight available. Some devices may not work as well if the acquired energy from the sun is insufficient. In some cases, power may totally fail if solar energy is limited or unavailable.

On Installation

Even though solar cell panels are readily available in most hardware stores and the internet, not everyone is still capable of installing the devices properly. The initial setup costs may be very expensive for some individuals. Women may especially find that tasks hard to do unless they rely on a professional to do all the work. Installation will depend on several factors and will need careful study, such as the angle of the sun, the position and area where you need to place the solar panels and the number of hours to complete the project.

On Purchasing

Purchasing solar power systems may be more expensive for first-time buyers. Those who have been used to the old system may have to spend more initially. Overall, the cost for maintenance begins to taper down because the sun is readily available and free. Some people, especially those coming from the third world countries may not have available solar cell panels ready for purchase. They may have to order online. The professionals needed to install and maintain the system may not also be available in some areas. The fees, if ever, might be more expensive. You have to compare the options first.

Homemade Solar Panels

English: Solar panel Български: Слънчев панел (Photo credit: Wikipedia)

As the cost of professional fees is quickly rising nowadays, people are becoming more reliant on their own skills and effort in building things. There are now a lot of DIY or do it yourself solar panel kits available at your local hardware store or on the internet. You can order and have the materials delivered right to your doorstep in just a few days. You can even finish the entire project in just a matter of hours. Here are some things to learn first.

Seeking Resources

You need to look for the right resources first. You can actually build your own solar cell panel for only $100 or less by finding the best and most affordable sources. You can start looking for green companies. These companies offer some of the best prices and high quality materials to encourage people to choose environmentally friendly options in acquiring energy. You can also look for private sellers and online companies on the internet. Make sure you read the company background and objectives so that you can fully understand the processes and types.

The prices of resources will differ, depending on your setup, the materials you want and the brand. You should get to know your source more. Determine the method of payment, the method of shipment and when you expect the goods to arrive. Usually, it should take no more than 7 to 10 days for your stocks to arrive. Other states may only expect 3 days to get their package.

Starting Out

First, cut a couple of rectangular copper sheets. Each should be about the size of a stove burner. Wash a piece of the copper throughout, then use the sandpaper to take off any presence of corrosion. Lay the copper sheet on the burner. Turn the burner on to maximum heat. Watch the copper very well. You will observe that the colors change as the copper starts to oxidize, and gently transform to black. Let the copper stay on the burner for about 40 minutes or up to the time that a thick coat of oxidized black material turns up.

Turn the heat off on the burner, then let the copper cool in the air. This process should take only around 20 to 30 minutes. Slowly scrub the copper using your hands under running water to eliminate majority of the easily removed parts of the oxidized coating. Do not attempt to take off all the coating or scrub vigorously. The objective is to remove the regions that can easily be taken off. Do not damage the copper that stays below the oxidized layer. This is needed to build the solar panel.

More Steps

Cut the top part of the plastic bottle off, forming a makeshift bucket. Take the second copper piece, then bend it to fit the bottle shape. Slide the second copper piece into place along the inner side of the bottle. Do the same with the heated piece of copper. The two pieces should not touch each other. Link an alligator-clip lead to every copper.

Connect the lead from the second copper piece to the positive terminal of the micro-ammeter. Stir salt until fully dissolved using hot water. Pour the salt water into the bottle. Check the micro-ammeter. This will be your battery. Position the apparatus under the sun and see how the charge rises as the solar cell panel changes the energy of the sun into electricity.

What is the Best Solar Energy System

With the recent advances in technology in recent years, being able to produce viable and clean energy to be used to power your home is now a reality. Alternative sources of power and energy will not only help you avoid burning fossil fuel to help provide electricity for your home, but will also help you save a considerable amount of money on the cost of your utility. One of those alternative energy sources is solar energy.

There are actually a number of different solar energy systems that are available in the market today. Since solar energy has become more common and more viable in the recent years, developers have begun to develop different solar energy systems that you can choose from, depending on your needs and limitations. Choosing a solar energy system that would fit best for your home is not necessarily an easy thing to do, which is why it is important that you learn how to choose the best one in order to get the right type of solar energy system for your home. Here are a couple of hints.

Know Your Solar Energy System

Before anything else, the very first thing that you must do is you must make sure that you know what different solar energy systems there are that you can choose from. Basically, there are two different types of solar energy systems, and those are the photovoltaic (PV) panels and solar thermal systems.

Photovoltaic Panels
Photovoltaic panels are solar energy panels that convert solar energy and turn them into electricity that you can use to power up most of your appliances and household lighting, and should only be used for those particular uses. Unfortunatley, among the solar energy systems that are in the market, photovoltaic panels are considered to be one of the more expensive ones, if not the most expensive in the solar energy market today.

Solar Thermal Systems

Solar thermal systems, on the other hand, simply generate heat, and are well-suited for boilers, furnaces and water heaters, as this type of system allows you to make heat using direct solar energy at a much lower cost as compared to using conventional energy and electricity. However, if you want to retrofit your home with one of these solar thermal systems, you need to sacrifice a little bit of space in your home. The good thing about using this type of solar energy system though is that you will save up to 80% of your total energy cost per year.

Calculate Your Energy Cost

Once you have a much better understanding and grasp of what solar energy systems are out there, and how they work, you simply need to learn how to calculate the cost of your energy consumption. This will actually help you determine which type of solar energy system you should choose from the two. When calculating the cost of your energy consumption, you need to create a list of all the things that might need energy and electricity. Include appliances, lighting, water heating, space heating, space cooling and air conditioning. If you can, try and figure out first if there are ways that you can reduce your electricity and energy consumption without having to resort to retrofitting your home with solar energy system.

Building Your Own Solar Cell

Řezy solárního panelu. (Photo credit: Wikipedia)

Solar panels are already considered very cost effective because these provide renewable source of energy. You can actually save more by making your own solar panels, instead of having to buy from a store or hiring a pro to do the installation. You can get a lot of financial benefits by maintaining the material properly. Expect solar panels to last for up to 3 decades if well-maintained. Here are some tips on how to begin your project.

Starting Out

Begin with the sandpaper and use it to scour the different regions of the copper of one of the available sheets. There should be no corrosion whatsoever on the copper for the process. Wash the copper sheeting using water, soap and either a sponge or a towel. You should allow oil from your hands to get on the copper. Tower the copper until dry. Make sure that you do not touch it directly. Use tongs to position the copper on the hot plate. Switch the hotplate on as warm and hot as possible.

Cook the copper using red hot heats for about 30 minutes. Use a thick black layer of oxides and allow to form at the surface of the copper. Be sure that you do not leave the copper unattended while you are cooking. The oxide layer and the copper below it will cool at various speeds, leading the two to separate. The process can be violent and can lead to accidents if not properly done. Be sure that you do not get too close or leave flammable items near. It will take around 20 minutes to cool everything to room temperature.

More on the Process

Wash the copper in plain water carefully. This will ensure that you get majority of the black pieces off. The red layer of cuprous oxide should remain on the metal. This will form right under the layer of cupric oxide. Get the cooked copper sheet plus the uncooked sheet then fit these into the plastic bottle. Bend each sheet outward so that no part of the two sheets will stay in contact with each other.

It is important that you clip one of the available alligator leads to the top of each sheet to connect these to the meter. The positive terminal of the meter must link to the uncooked sheet. The negative terminal must link to the cooked sheet. Dissolve two tablespoons of salt into a few cups of water. Pour right into the plastic bottle, allowing the water level to rise about 1 inch from the top of the sheet. Put the bottle out in the sun and observe the meter. The meter should rise consistently to about 50 micro-amps. Place the bottle in the shade and allow the meter to go down below ten. Finally, you have created your own solar cell.

More on Building

You can expect to finish the entire process in just 3 to 4 hours. It is important that you check out the different available resources first at your local hardware store and online so that you can get the most out of your budget. You should also consult a pro and other people who have tried building their own solar cell panels so that you can maximize the effect and get the energy you need to power your various devices.

How to do Your own Solar Power Generation

English: Solar Panel മലയാളം: സോളാര്‍ പാനല്‍. (Photo credit: Wikipedia)

Before, solar power or solar cell panels are only available in commercial areas and hardware stores. Nowadays, more and more people are trying DIY or do it yourself kits. You can expect to have your own setup in just one day, provided that you have an easy kit to start with. Solar power can be achieved right in your very own home, without the help of a professional. Make sure you follow the instructional guide carefully for the best results.

Building Your Own Solar Power Generator

You can use parts that are available on the internet or your local store. You can create a tiny solar power generator with a budget of only $200 to $300. This is ideal for power failures and life outside the power grid. The setup can also effectively power the modem, television, DC appliances, computer, cameras and lights. You can use this in cabins, archaeological digs, tents and camping trips. This is the ideal setup for people who travel to undeveloped regions and countries.

Initial Steps

First of all, you need to make or buy yourself a tiny solar panel. You can get a device rated at 12 volts or higher for only $100 at a marine supply store or RV store. Next, purchase a battery. Experts recommend that you get rechargeable batteries from available green companies. Get any size of deep cycle 12 volt lead/acid or gel battery. You will need the deep cycle battery for nonstop use. The type in the car is a cranking battery, which is good for starting engines. You may also want to look for bargains and other good deals that will cost only around $50 to $60.

Next Steps

Take a battery box where you will put the generator in. The box may only cost around $10. It is ideal for covering the exposed terminals just in case you have kids inside the house. If you want to install the system in a cabin, pump shed or boat, you can skip this step. Purchase a 12 volt DC meter. This will cost you around $25. Purchase a DC input. The triple inlet model is recommended. You can purchase this for only $10 at a car parts store. The device will be good for powering DC appliances like lights, hair dryers and vacuum cleaners.

If you intend to power AC appliances, you will need an inverter. The inverter converts the stored DC power in the battery right into AC power for majority of household appliances. Measure the watts that you will need. Cheap inverters of various sizes can be purchased online too. Use a drill to attach the meter and DC input to the top region of the box.

Charging

Next, use insulated wire to connect the meter to the wingnut terminals found on the battery. Link the negative pole initially. Only handle a single wire at a time. Link the DC inlet straight to the battery in a similar fashion. Link the solar panel to the battery the same way. Shut the lid using a bungee cord to keep everything tight. Position the solar panel under the sun. It will take 5 to 8 hours to charge dead batteries. You can power different devices like fans, lights and radios.
