If you are thinking of going green, solar panels might give you an interesting solution. Quietly they will convert sunlight into electricity, giving you DC voltage as the final output. For your home devices this voltage should be inverted to AC.

To process the DC voltage into AC voltage there are some additional parts needed. Basically what parts to buy are determined by what set up you prefer to. The first option you may consider is on-grid or grid-tie system. On-grid is widely preferred by people because it is cheaper than other systems. Having on-grid means you send the solar electricity to the utility grid.

What makes on-grid system cheaper? It is because we don’t have to store the solar electricity in solar batteries so the only main parts we need to buy is solar inverter only. By eliminating the batteries we cut down the solar cost because these batteries are expensive, however this system also has a downside: During power outages you will be left alone without electricity supply.

If you need power during electricity blackout you can pick up the second option. Similar to the first option the solar electricity is also routed to the grid but a battery backup is added to the solar inverter. Note that this system is more expensive because you need to buy the solar controller, solar batteries and also solar inverter that is different from the inverter we use in the first option. They contribute a significant increase to the solar cost.

For people living in isolated places there is only option left. Due to no power lines available you can only get the off-grid system. This system is totally independent and use solar energy as its main energy source. Here you will need to buy solar regulator, batteries and solar inverter. In addition to the main parts you will need to buy small accessories as well such as terminal connectors, wiring, fuses, etc. This also applied to the other two options above. To back up your solar electricity you can add a gas generator or wind turbines to the system in case of cloudy days.

Now let us see how much really they will cost you. To make a rough estimation you can think about $15K to $60K. The cost will actually depend on how far do you want to substitute your fossil powered electricity. A 100% substitution is not recommended at all because the cost will kill you.

The other factors that also contribute to the price are the quality of solar parts and installation cost. Solar inverters for example has a wide quality range and solar installation cost differs from one company to another.

If you want to reduce the cost there is a good solution offered by the US government. Installing green energy in your house will allow you to get 30% federal tax benefit plus other tax benefit given by the states. By sending the electricity to the grid you also get some credits from the utility company.

There is no need to fully go with 100% solar electricity, even starting with 15% substitution will make a difference. You can always expand your system later on.

If you assume that you need a one time investment only for this system you are probably wrong. Some solar parts have lifespan shorter than the others so you may need to replace some of them after years of operating time while other part such as photovoltaic panels can pass 20 years without problem. It is recommended to add this factor into your solar cost planning.

If you are in doubt you can always search for online help. There are a lot of solar companies out there and they will be glad to help you finding the best solution for your home solar system.

If you have ever been hit over the head by the boom of a sailing boat as it tacks, you will have a painful reminder of the force that can be generated from the wind. If you are lucky enough never to have had that experience, just think of the devastation that hurricanes and twisters can cause to homes during hurricane season. The wind is an extremely powerful and potential force. Anybody that decides to make a home built wind turbine should be aware of this power but also the limitations. This article will explain some of these issues so that you are more informed when it comes to building such a renewable energy system.

A wind turbine uses the wind’s kinetic energy to make mechanical energy which is then converted to electrical energy. The wind turns a rotor that is connected to a motor via a transmission shaft. The motor then creates electricity that can be stored in a battery or used in the home.

Before you build your own wind turbine, you should be aware of the upper and lower tolerances of such a system.

The lower tolerances are basically the wind speed. You need to have a constant wind speed of around 10-15 miles per hour to make such a system viable. If you don’t get this wind speed, the turbine will not generate enough power to make your efforts worthwhile. You should probably consider another type of renewable system, like a solar power system.

Another consideration with regards to the viability of a home built wind turbine is the space that you have. You will need a fair amount of clear space to locate the turbine. If you live in a densely populated area there is also a good chance that there will be many obstructions, like trees or other building that will get in between your wind turbine and the wind. This is no good and again will make your efforts worthless.

In terms of the upper tolerances, you should be aware of the highest wind speeds that your location has had. You can get in touch with the local meteorology office or weather bureau for this type of information. They should have plenty of historical data on this.

Although history can teach us nothing about the future, it is the best way we have to plan for any future outcomes. When you know the highest wind speeds, you should ensure that components like the tower can tolerate these kinds of speeds without buckling.

You can make your wind power generator, go to wind power kits for reviews of popular manuals that show you how to do this, including a Home Made Energy Review

Many people like the idea of using solar power to reduce their home energy consumption. Using solar energy has the potential to reduce your monthly utility bill because some of the electrical components can draw power from the solar system instead from the main power grid.

A residential solar kit can be expensive. Be prepared to invest $8000 or more. If you want to cut cost, you can build the solar system via a Do It Yourself (DIY) approach.

Do you know there are some steps you can take which can reduce your solar budget substantially? You can cut cost by following the 3 approaches below.

1) Check for air leaks – One of the major energy cost is on air conditioning. To save cost, you can start by checking for air leaks in your house.

During winter, cold air leaking into your house will increase your heating bill. During summer, hot air seeping in will jack up your air conditioning cost.

2) Install attic exhaust fan – This is a very simple and inexpensive approach. Installing an exhaust fan in the attic can cool down your living rooms substantially.

During summer days, hot air is trapped under the roof or in the attic. The hot air will tend to heat up the rooms beneath it. By using an exhaust fan, it will suck out all the hot air therefore keeping your home cooler.

3) Install window screen – This is another simple and inexpensive step you can take to reduce your air conditioning cost. You can cool down a room by installing window screen which has direct exposure to sun light.

Some people do it wrong by installing the screen inside the room. This will make the room hotter because of “green house effect”. The right way is to install the window screen outside the window. You can save cost further by using inexpensive wood or bamboo screen which is replaceable.

Many do not realize this – building a solar panel is different from building a solar power system. A solar panel is only a part of a solar power system, whereas the solar power system consists of not only a solar panel, but also an inverter, charge controller and battery banks.

For a complete solar power system, the above mentioned three items are essential. Let us look at each of them:

1. CHARGE CONTROLLER

The reason you want a Charge Controller is to prevent a sudden surge in the output of your solar power system, as the surge can damage the electrical appliances connected to your system.

Most of what a household needs is only a basic Charge Controller. You can choose to save money, until you decided to get an advanced one for their more professional features.

When you choose a Charge Controller, get one whose specification fits the output current of your solar power system. Take note that some salesperson will recommend you to hook up two or more affordable Charge Controllers instead of getting a large one for your system, saying this will save you cost. However, usually a large Charge Controller performs better than a few small ones cascaded together.

2. BATTERIES

The solar power system does not generate energy at night, and does not perform well during winter time or rainy days. This is why we need batteries to store up the charges generated from the system for use in these conditions.

You need to perform some calculation before you specify the size of batteries you need. Besides, you have to think about how you want to use the energy you store up: Do you want it to get you through rainy days only? Do you want it to provide you electricity overnight only? Or do you want to have reserved energy for three days to a week?

Ideally you should choose batteries that are very large so that it can store much more energy than what you need. However, we need to consider the cost and the physical size of the batteries. So it is not realistic to get oversized batteries. Moreover, if your house is still tied to the grid, you only need to get a small set of batteries to get you by cloudy or rainy days.

3. INVERTER

Most of the electrical appliances in our house take in Alternating Current (AC) to function. The output of a solar power system, however, is Direct Current (DC). To allow the electrical appliances to draw energy from the solar power system, an inverter is used to convert the AC into DC.

Choosing an inverter for your system is straightforward. You only have to select one according to the demands of the AC side of the inverter. You have to make sure that the inverter is able to fulfill the needs of the loads (the electrical appliances) in your house. Also, remember to add in a reasonable buffer in case your load increases.

Most DIYers do not have sufficient professional technical knowledge to decide the correct Charge Controller, batteries and Inverter to use, and how to hook them up to form the complete solar power system. This is one of the times when it is wise to seek professional help, because it can not only save us from guess work, but also prevent us from wasting money and time due to getting wrong parts for our solar power system.

A wind generator blade is the most important component in the working of the wind turbine. These blades are curved and large, and they are quite similar to the propeller blades of an airplane, and these blades are the source for generating power. Creating your own wind generator blade is an excellent method to bring down the cost of making a wind generator and it also gives some self gratification. This article gives a brief look at how to build the homemade wind generator blades to save the money.

It is very important to choose the correct products to make the blades as it is directly connected with the efficiency of the wind generator. Some of the materials that are used to build blades are wood, metal, and plastic. Woods are considered as the good choice for the yesteryear traditional wind generators, metals are very easy to work with, and plastics are the ideal material to make the blades. We recommended to build the blades with PVC pipes because of so many reasons such as the wood can crack, wood absorbs water, and the crack makes wood to absorb water. Also, wooden blades can be difficult to make and can be very time consuming. Other DIY sites make different choices and those are also good as long as you have a good eye on your own skills.

For making three wind generator blades, you require about 4″ or 6″ PVC pipe of 4″ long and for wind blades that are 30″ in length, you can make use of 4″ diameter PVC pipes. To make blades between 30″ and 48″, you may require PVC pipe of diameter of 6″. First, the middle line should be drawn down the pipe, as the blades branch from the center line and thus makes more power. The blade should be made pointed for about 5″ at the root and 2 ¾” at the other end, and then cut the blades on the drawn area.

Smooth the edges near the cut part to get a good finish and before equalizing the blades, paint the blades with the UV protective paint. UV protective paint shields the PVC pipes from getting brittle due to the sunlight exposure. For equalizing the blades, place them on the hub and place the hub on the piece of steel rod with few pillow block support. Spin the blades to mark the bottom blades and trim the bottom one a little more than the others, as balanced blades are safer than the unbalanced ones.

It is important to remember that saving money is not the only criteria when you decide to make or buy your own wind generator. Your skills, the amount of power you want to create and the investment you are willing to make are also things to consider. You can buy DIY plans here because making your own wind generator blade is also a nice job to do. Or look at a ready to go system like the Skystream 3.7. Whatever choice you make you will save money in the end.

Learning how to make homemade solar panels is a fun and easy process that many home owners can take advantage of. Solar power is a renewable energy source that has many advantages over grid-power which are not only good for the environment, but for the homeowner’s energy bills. Initially, buying a solar energy system may seem very expensive, especially in the solar panel installation. With a basic knowledge of where to find the materials needed and the know-how to build solar panels, you too can reap the benefits.

Home solar power systems are not as complicated as most people assume. You can find most of the materials needed at your local hardware store and the solar cells themselves can be purchased in bulk lots off eBay. Do your homework though, research a seller on eBay and find out as much as you can about the cells you buy. Typically the cells you will want to purchase are 3×6 mono-crystalline solar cells, but be aware that these cells are very fragile and paper thin so handle with care. Once you have found a good deal on some solar cells be sure to inquire about how they will be shipped, most cells are dipped in wax to provide a more secure method of shipping them.

Also, you will find, some cells are sold with metal ribbon wire already soldered onto them and some that are not. The best option is to shop around and find solar cells that come with the metal ribbon wires already attached to save some time since soldering those ribbon wires onto the cells is a tedious and painstaking process, which adds to the possibility of damaging the cells while being handled. If you’re careful though, and take your time, you can certainly achieve the desired result with minimal damage done. If you purchase cells that are dipped in wax for shipping, you can heat them in water to remove the wax.

Once you have your cells, generally you will want to connect 36 of them together to produce about 18 volts in direct sunlight. This is an adequate amount when charging 12-volt batteries and ideal for home use. The metal ribbon wire is attached to the front of the cell and you attach the excess ribbon wire to the back of the next cell with solder accordingly until you have a series of 6 cells, repeat this process 6 times to have 6 series of 6 cells each, totaling 36 cells.

The next step is to construct a shallow box to house the cells in series to collect sunlight. With 36 cells linked together, the option is yours as to how you wish to construct the box, using them in a series of 6 and aligning them side to side in 6 rows will roughly leave you needing a 46inch x 24inch shallow box. Use a good strong silicone material to fasten the cells and braided wiring into the box and cover it with plexiglass. You will also need to have blocking diodes in the wiring to ensure there is no discharging of the energy being collected, otherwise the wiring is pretty straightforward, just attach all the ending metal ribbon wire ends together with bare braided copper wire or the like. Before you begin sealing up your shallow box with the cells in it be sure to test the solar panel in sunlight with a volt-meter to make sure everything is working properly.

Now that you have constructed your first solar panel the choice is yours as to how you wish to distribute the power it generates and when more power is desired just repeat the process as many times as you like. With the proper electrical components and a special meter from your utility company, any excess power your panels generate can even be sold back to the power company making the ability to make homemade solar panels a very attractive venture.

Learn how to make homemade solar panels that will help you save money each and every month on all of your utility bills. Please discover a way for the government will pay you for using energy efficient systems.

Traditional hot water circulating system, warm water circulating system and the demand hot water system are three main systems that solve low flow problem of hot water. These systems are very helpful in providing instant hot water and saving water wastage. Let us discuss about them in little detail.

Traditional hot water circulating pumps uses coiled plumbing through all the fixtures and a single return line on last fixture. A lot of energy is wasted in these water heaters as a constant water temperature is maintained in the pipes all the time. One drawback of these water heaters is that they can not be used with all tankless water heaters.

In warm water circulating systems, a pump is used under bathroom sink that works in a way like temperature controlled traditional hot water circulating system operates. However, in warm water circulating systems the control temperature is set at a lower level. You can obtain instant hot water with the help of these water heaters. One drawback of using it is that many times hot water enters in cold water lines and for getting cold water you need to flush out the hot water first which leads to water wastage.

Hot water demand pumps speed hot water from your water heater to your fixture without running any water down the drain. In a demand system, you can push a button to start the system when you want hot water and when hot water arrives at the pump, it shuts off.

No hot water gets into the cold water line and when you turn on the tap you nearly get instant hot water. With the help of the pump that is located under the sink, all the fixtures in the bathroom get hot water fast.

Demand pumps help in saving around thousands of gallons of water and also save a lot of energy. Due to both of these reasons, they are considered very green. The total electricity consumed by a demand pump in a year costs somewhere around $2. These systems are not very expensive and can be obtained in $200.

You can use hot water demand system with any of the tankless water heater. But keep one thing in mind that when you use demand pump with tankless water heater the flow should be able to power on the water heater.

Hence, in short a hot water demand system saves time, water, money and enables you to enjoy the instant hot water service by simply turning on the hot water faucet.

The many advantages of solar energy are why you should highly consider changing at least part of your power to solar. Use of solar energy over the choice of oil or natural gas can be extremely beneficial to the environment for starters.

The sun and solar energy will always be around. As long as the sun doesn’t disappear solar energy will always be accessible to you. Yes it is true that you won’t be able to use it at night or on cloudy days. But there are ways that you can store it up, so you may not need to worry about those times.

But if you consider oil as a source that will always be around, well we all know that isn’t true. It takes millions of years for that oil to actually be made. Once the resources are used up it’s going to take that much time for it to be produced again. And those reserves well they are going down too quickly.

With solar energy you will not be adding in pollution to the air. While on the other hand when you burn that oil for use it will create greenhouse gases and carbon dioxide that is released into the air. We all know the problems that are created by those gases. Plus the problems that arise when an oil spill happens it’s extremely damaging.

Solar cells are something that requires very little maintenance and they are something that will last a long amount of time. It may cost you some money to first get set up with your solar panels and the other accessories that are needed. However, keep in mind that it’s a onetime cost. Something that month to month will cost you very little money. The only time you will need to spend is when you have to fix something. Oil on the other hand is something that goes up quickly and all the time.

The process of installing products and lights that are run by solar power are simple to do. All it takes is a little bit of wiring, and you really will never find yourself having to dig for a supporting trench.

Of course being good for the environment and the cost are the two biggest reasons why solar energy is much better than oil. Just remember that you may find ways that you can make your own solar panels and save money.

All homeowners are aware that the cost of energy is rising and continues to increase every single year. Many people are now searching for a way to reduce their electricity bills. Instead of cutting back on the amount of power that we consume it is now possible to install a device such as a wind turbine that harnesses a renewable source of energy. There are many kits available in the market but it is also possible to make your own wind turbine using some basic tools and material.

If you decide to install a wind turbine then you will see great financial savings in your energy costs as well as helping to protect the environment. Many people now see wind turbines as a more productive means of alternative energy creation when compared to solar cells and panels. This is because wind turbines can produce electricity 24 hours a day. They do not even need a strong wind. Also, if you have a property that is in a remote location where it is not possible to connect to the national grid, then they are ideal. You can easily learn how to make your own wind turbine and harness household wind power to generate your own electricity.

To make your own wind turbine you will require some specific materials. These can often be purchased in your local hardware store or you can buy them through the internet. To put all the pieces together should take no longer than a weekend for an individual with experience of DIY.With a little skill and a few readily available materials, you can make your own wind turbine and start saving money on your electric bill before you know it.

The necessary parts will include a motor, a mounting, a tower, and blades. Depending upon your energy requirements a turbine can vary in size. Most people will use a 30 volt motor. If you understand aerodynamics you can make the blades from an old PVC pipe otherwise you will have to buy specialised blades. The tower can often be built from a strong piece of metal pipe that needs to be securely fastened.

Other equipment would include an array of batteries to store the power that is generated and a controller that regulates the flow of energy to the batteries. Since it is so simple and relatively inexpensive, ore and more homeowners are learning how to make their own wind turbine. It will help you to save money, reduce pollution and gain independence from the electric grid.

Whenever working with electricity you need to ensure that safety procedures are followed at all times. Any electrical device needs to be protected from water.
