Most family homes spend around a third of their energy budget on heating water for daily uses. Heating water for showers, baths, cleaning clothes and a host of other things is done by electricity or gas supplied by utility companies. However the resources that are used to create this electricity or gas are not renewable and are proving increasingly harder to find as more is used up. This puts the pinch on the average household consumer that is finding utility bills steadily going up at above inflation figures. This will only continue as fossil fuels get harder to find and extract. Thus consumers, governments and even the companies that supply electricity are looking for alternatives that are less harmful to the environment and are a renewable resource. Solar power is a good way to heat water and has been successful for close to 100 years now. This article will discuss cover how you can save money on your household energy bills by installing a solar power water boiler.

Solar power water heating is possibly the simplest application of solar energy that we have today. It is simply a matter of harnessing the thermal rays of the sun and applying it to water. There are two common ways of doing this. They are known as the flat plate collector and batch collector systems.

Flat plate collectors are a system of pipes that allow water to pass through them from a storage tank and into the plumbing system or another tank. The pipes are designed to allow the sun’s energy to heat the water as it passes through the piping. It is generally attached to a black backing that attracts and absorbs the sunlight. The piping is also place in a location that will get plenty of sunlight like the roof.

A batch collector system is a water tank that has been modified to get the most out of the sun’s energy. This includes black surfaces that absorb the thermal energy. The tank is located in a place that will get lots of direct sunlight and is close to the house. The roof is a popular location.

The water supplied by either of these systems can then be used in the regular plumbing system of the house where it can be used for everyday usage such as showers, washing up the dishes and cooking. Even though the home will still be connected to the electricity or gas that normally heats the water, the solar heated water will require a lot less energy to heat it than ordinary cooler water. This will help to save on energy bills.

The cost of purchasing and installing one of these systems is still fairly expensive depending on the size of system that you require. However once the system is installed, the running costs are virtually nil and the system itself will last up to 25 years. When you factor this into the buying equation you will find that you may have paid off the initial cost within 5 years. The rest of the time you will be saving money on your energy bills. This can really add up over a 20 year period.

The use of solar hot water panels has been escalating in homes all across the world in countries such as Italy, Australia, America, Spain and France. Ever since the late 1970s these systems became a huge hit in the USA. In fact, so popular are these solar heating systems, figures reveal that more than 40,000 house holds in the UK alone are reaping the benefits of them

In the world today, having such technology is extremely beneficial. A couple of simple examples of the tremendous profits that are involved with the use of these systems would be in the form of getting hot water and saving on energy bills.

This system of solar panels is not only of great use in homes but it is also used to heat residential swimming pools. As heating of water for swimming pools can prove a very costly affair on an annual basis, this job is better and more cost effectively done now with the help of solar power, much to the benefit of pool owners all across the globe.

In certain parts of the world, an average household is now capable of getting hot water for the entire house in the summer, just by the use of these solar heaters. This has tremendous economic advantages. Hardly surprising is it then that solar heating systems have been in use to warm households since ages. An assorted variety of these systems are now available but the actual choice depends upon the person or persons concerned.

The dimension and type of the solar heater, big or small, is largely determined on the size of any household. People in some countries are given rebates to take advantage of these solar heating systems. This is also a crucial factor in determining the usage by people.

For example places like Arizona, New Jersey, California, Colorado, to name a few, offer massive rebates for people to avail of these systems. In fact, individuals are even compensated for the power they produce, just to help offset the initial costs of the investment.

There has been a tremendous surge in the need for the use of these solar systems since the last decade. More and more people are recognizing the importance of the use of them. This has resulted in a massive cut by around 40% in the cost to set up these solar panels in residences. If ever anyone from anywhere was even thinking of using these solar heating systems, now would be the right time to put their thoughts into action and start using solar hot water panels.

Just because your house cannot be connected to a major power line does not mean that you have to spend your days in darkness and without power. Living off grid connections makes power accessibility a concern for some

This article will cover some basic information that you will find helpful if you plan to build your own homemade Solar panel. You are not required to have special skills, and neither to spend a huge amount of money. In fact, you can build a solar panel with as little as $200.

Using the sun as an energy source is becoming more and more popular and people try to use as much as they can from this never-ending potential. Even if solar power is not as effective and powerful as fossil fuel, it can still be used like oil or any other fuel in your house. The equipment you will need to build your own solar panel is not very difficult to obtain.

Saves money – Setting up your own solar energy panel will save you the money that you would have spent on a professional firm if they would have done the job. Installation is a one time cost and this is recovered in a few years time. You save a lot of money on the energy costs as well. Also, maintaining the solar panel does not cost much.

For building your own homemade solar panel you have to purchase a DIY kit that generally costs around $50. The kit comes with an instruction guide that provides all the instructions you need to make your solar panel.

Wind power, like solar, has received such benefits in the recent years that has increased the efficiency of living off grid sources with a wind hookup. A major wind turbine may be required for a larger household — the cost of which is substantial, but individual turbines can be rented by multiple tenants and share the price burden — but for a smaller cabin or basic plug in, a turbine the size of a two story building may be all that is required. Wind turbines require a large amount of maintenance, however, as owners must frequently oil the blades to reduce friction.

Then you have to determine which is the spot that gets the most sun during the day. Also, you must decide what type of solar panel to install, as there are different kinds of panels and each of them is used for different purposes, such as for cooking, water heating or other necessities. The most commonly used type is the photovoltaic panel that converts the solar energy into electricity.

Basically, these panels convert the natural light into electricity as the generated solar power is headed towards the batteries. So the battery is nothing more than a device that stores the electricity until it is needed. This being said, do not forget that the greatest benefit of using a homemade solar panel is that this is the most earth friendly option you can choose.

While many people think of solar energyas a relatively new idea, in fact the concept dates back to hundreds of years ago, with the ultimate Renaissance man Leonardo da Vinci having drawn some prototypes in his infamous notebooks.

This technology can be simple, or can be so complex that it can operate an international space station. In the case of providing enough power to run a household, there are solar panels that can be attached to your roof to harness the rays from the sun. The question that many people have is how these rays are then converted into electrical power, with a seemingly endless renewable rate.

The solar panels are the most important portion of any solar energy system. They will produce direct current electricity by using the rays of the sun, and then it is run through the inverter and switched over to alternating current electricity. The AC power is the type that is used by the utility company’s own power grid, and can be fed directly into this grid tie system with the use of a combiner box. Those are, in essence, the main functions of this type of system.

When these smaller cells are exposed to sunlight, (which is why they are usually placed on the roof or any surface that will be under the influence of the sun’s broad rays), a basic chemical reaction occurs. There is energy that is created from photons of the sun’s rays hitting the surface of the panel, causing the electrons of these cells to be basically hit out of their normal orbits and released, causing a strong current of energy.

However, the coal industry still won out and his research was cut short. The research was continued with the efforts of other scientists who built upon the refrigeration devices, such as William Adams, Willoughby Smith, and Charles Tellier, who was considered the father of refrigeration. In the 20th century, the work was continued by government organizations. In fact, the space programs during the great space race at the turn of the century used solar technology.

A number of factors can influence this solar panel output then, depending on the cells themselves and also of the outside elements that may have an effect on them. Weather conditions, for example, can play a large role in the overall efficiency levels. If the panels are covered by cloudy conditions or excessive shade, the output will not be as great. The angle of the solar panel should also be such that it receives the highest amount of direct sunlight that is possible.

Buying into a grid tie system allows people to do just that from the comfort of their own homes, while at the same time saving money and being able to say they made a difference. The first step is to gather more information about solar energy and how it could work within your own household, which is much easier than many people think.

When building solar panels what solar cells to buy can be quite a challenging experience. I know when we first started our solar panel project it seemed like rocket science to me. The first thing you want to look at when buying solar cells is how much power do they put out.

In order to build a solar panels that puts out a decent amount of power you have to be picky about what cells you choose. When looking at cells you’ll see that they’re rated by how many volts and amps they put out. By multiplying the two together you get how many watts each cell produces.

Since each solar cell produces 0.55 volts (that’s why so many are needed to make a solar panel) you’re looking for cells that produce over 2 amps. This means that each cell will produce 1 watt. My personal favorite solar cells are 0.55 volt x 3.98 amps which are about 2 watts each. These are powerful enough to build a 72 watt panel (which is the smallest I build).

Un-tabbed cells need to be wired and strung together in order to be of use in panels. If you are inexperienced in this type of job, there’s a great chance of overheating the cell and deeming it useless. And that’s money down the drain. Time is also a factor as you would need to wire 36 cells before making the actual panel.

Even though I’m experienced at soldering I still use tabbed cells because I’ve broken more than a few while tabbing them. Although tabbed cells are a little bit more expensive (usually around 20%) their ease of use cannot be surpassed.

By choosing untabbed cells over tabbed ones you can greatly save $100. If you think that $100 is worth several two or three more hours of your time, then buying untabbed cells might be for you. Imagine how much more you can save if you build more than one solar panels?

When building your solar panel remember that when buying cells you need to multiply volts and amps together to get the watts each solar cell produces. You multiply the watts each cell produces by 36 to figure out how many watts your solar panel will be. If you keep those numbers in mind when buying solar cells you’ll build many successful solar panels.

I built my own solar panels and a wind generator and saved well over $30,000. I get a cheque from the power company because I produce more energy than I use. If you’d like to learn how you can do the same check out Buy Solar Cells.

People can be attracted to solar power for different reasons. Most do want to make difference to green house emissions. Most people going to solar energy want to power their home in order to be off the grid. Or they may want to be protected from service interruptions. Many will adopt a DIY approach to home solar power.

Over the last two years electricity prices have risen in most capital cites and we are almost certain to face more rising electricity prices over and above the cost of inflation into the foreseeable future. Solar Panels

Energy demand is projected to grow steadily over the next several decades, and supply will become more constrained (or expensive) as governments from all over start incorporating the cost of CO2 emissions into the cost of generation from fossil sources. This will also act to drive solar prices down, as increased demand creates greater innovation and greater economies of scale. Hence solar is being seen as a solution.

Solar energy would not be affected by the supply and demand of fuel for it is free and it doesn’t pollute the atmosphere. It is natural and pure. It would provide us with better health.

In the beginning you may pay a minimal amount to be solar power efficient by purchasing a solar source. You can buy indoor and outdoor lighting, solar power windows and insulated doors in order to make your home more solar efficient. After that initial expense you don’t have the expense of paying a monthly bill to keep your service on. This also promotes others to use solar power to be more efficient.

Before putting the transparent cover, you need to test the panel outputs with a voltmeter to ensure that it produces the desired voltage. You can boot the panel voltage by connecting the solar cells in series. For this, you need to connect the positive lead from one cell to the negative lead of the other.

You will need to dig out your electricity bills for the last year. Work it out for an entire year and you can then determine the average usage on a true daily average. Add up the number of kilowatt-hours you have used over the year, and divide that number by 365. Now you’ve got your average usage in kilowatt-hours per day. You can then start looking at hooking your solar energy system to the grid-connect systems that are available. You need to think about your location and calculate how much electricity they can produce. These are based on calculators which each electricity supplier or provider will have on their website.

If, for example your household is using an average of 20 kilowatt/hours per day, that means that a 2 kW system producing an average of just under 10 kilowatt/hours per day would provide almost half your electricity needs. Note that these calculations presume an optimum installation. Variations from true north in the southern hemisphere and true south in the norther hemisphere and from the optimum tilt angle will reduce the power output. Solar power for homes is only fully efficient when every photovoltaic cell in every panel in your system is exposed to full sunlight. For diy photovoltaic solar panels for the home, note that even the smallest shadow of a tree branch on one photovoltaic cell can dramatically decrease the efficiency of the overall system. The solar energy collected is converted to electricity through the PV process.

How to Make Solar Panels – Parts List
When it comes to making your own solar panels, cheaply, sourcing the parts correctly is everything. The basic components you will need include:
1. Solar Cells – To produce the power.
2. Tabbing Wire – To connect the solar cells together.
3. Solder – To attach the tabbing wire to the solar cells.
4. Bus Wire – To wire everything together in a series when done.
5. Plywood – To use as a backing
6. Framing material (square aluminum tubing or 1 x 2 lumber) – To build a frame on top of the plywood.
7. Plexiglas or Lexan – To seal your assembled unit up, and protect your solar cells.
8. Silicone – To ensure the whole unit is sealed up.
9. Misc Hardware – Screws, etc to put it all together.

Broken solar cells are also an option, however it’s not recommended for DIY novices. The broken ones can really make your project much more cheaper because they are almost as effective as the new or second ones yet come at a fraction of the price. Being the most expensive components of a solar panel even a 20% change in the price can reduce the total cost of the project which should not exceed two hundred dollars.

Follow the instructions on how to make solar panels at home provided with these kits. These do it yourself instructions are quite systematic and easy to follow. A major component of any of these solar panel kits is the photovoltaic cells. Since these solar panels generate electricity by capturing sunlight, install them at a place where they get maximum exposure to sunlight.

Electricity generated by solar panels is not only cheap, it is also environment friendly. There are no harmful by products as is the case in generating electricity from non renewable sources of energy. By installing solar panels at home, you not only save on your ever increasing electricity bills but also do a great service to future generations by leaving a cleaner environment.

Step by Step to Make Solar Panels:
1. Tab Your Solar Cells – Cut two pieces of tabbing wire for each cell. These should be double the width of a cell, and then solder those wires to the cells themselves.
2. Wire the Cells in Series – With all of the cells tabbed, begin wiring the cells in a series. Solder the wires from the top of one cell to the bottom of the next cell ( – to +). Continue this until you have the number of rows you decided on before you started.
3. Build a Panel – Using your plywood and your 1 x 2, cut the correct size to house your series of cells out of the plywood and then build a frame around it.
4. Place the Solar Cell Series in the Panel – Place your solar cells in your panel. Before you tack them down using silicone, wire two more tabbing wires to the end of each series (so that you have a + connection off one side of the series and a – connection off the other).
5. Wire it Together – Once you cells are in the panel cut bus wires that can reach across to two groups of cells. Wire them together in a series so that you are wiring the positive side of one group to the negative side of the next. Continue this until all of your series are wired together.
6. Attach Your Final Wires – Take some braided copper wire and solder it to the + connection of the first series of cells, and then wire another piece to the – connection of the last series of cells. Run these wires out of the panel.
7. Test and Seal – With the wiring complete all that is left is to test your panel and then close it up. Take it out in the sun to test it. Assuming your voltage is what you expected, close the panel up using your silicon and Plexiglas. At this point you’re ready to wire your solar panel into it’s final position.

Using the sun to create an electrical current or heat are two ways to harness the energy from the sun. With the heat method we can concentrate the sun’s rays to heat liquids for either creating hot water for our homes or to create steam to drive a turbine. The other way is to create an electrical current. This is done by placing thin layers of silicon crystals in an array. These silicon crystals excite the electrons within them when the sun shines on the layers.

A solar system consists of two parts mainly; a silicon array and a AC inverter. Moreover, the system may use a battery for storing electric current. The silicon array that consists of many glass panels is expensive. For every watt of energy the amount spent is $4 while the cost of inverter is about $2500.

Mounting solar panels on your roof might add extra expense to your installation due to the fact that you will probably want to replace the shingles prior to mounting the solar panels. Once the solar panels are in place it will be difficult to perform any maintenance on the roof so having the roof ready to be maintenance free for the next 30 years or so might be beneficial prior to mounting the solar panels on your roof. Another option is to mount the solar panels in a clearing in the yard or installing solar shingles rather than solar panels.

Mounting or placing options will vary due to the directional setting of the house and the location of any obstacles that will shade the solar panels. If your house doesn’t have a roof slope that faces south then the ground mounting option might be the way to go.

These solar energy plants are helpful in summer season when the consumption for electricity is greater than the average consumption. In summer season the excessive heat from the sun can be utilized for running the air conditioning systems.

Solar shingles might be the new way to go. They are less of an eyesore and probably offend homeowner associations less. They also serve a double purpose by capturing and creating useful energy from the sun while protecting your home just as traditional shingles do. There is a little more installation labor due to wires from each shingle having to be connected to a central location but this might be a more suitable option for some homeowners.

Solar panels come in a variety of sizes and powers. Some typical power sizes seem to be around the 200 watt but they can vary up or down depending on the manufacturer. A rough guide to the costs of a solar panel are about $4 a watt, so a 200 watt solar panel will cost somewhere in the neighborhood of about $800, give or take $100. Of course this all depends on the efficiency of the panel and the drop off of efficiency over the years.

Proper planning is necessary for installing a solar power panel. The panel may not be sufficient to serve all the needs of the home owner but is sufficient to provide enough air conditioning during hot summer days and cool winter season.

Algae as Biodiesel

Biodiesel refers to fuel produced from once living organisms. It’s commonly produced into a liquid or gaseous state and a lot of people use Biodiesel for running vehicles or supplying electrical energy via a diesel generator. Since of the plentiful supply of algae feedstock in freshwater and other marine sources, large-scale studies have already been performed for the use of algae as a potential supply of biodiesel.

The production of biodiesel & large scale cultivation of algae biomass is grown in numerous locations throughout the world. The important fuels synthesized from algae oil are biogas, biodiesel, biomethanol, bioethanol, biobutanol and dry algal fuel (similar to powdered coal) such as the group Robert Fulton has created. Quite a few countries around the world have integrated highly sophisticated techniques for developing commercial-scale cultivation of algae and the United States is a front runner with this technology.

Benefits of Algae as Biodiesel

The fast growth of algae is a contributing ingredient for commercially manufactured algae cultivation. Many species of algae can double their mass in a day. In comparison with other biodiesel solutions this includes soybeans or jatropha, there are certain advantages of using algae this includes:

* The amount of oil from algae is comparatively much higher (about 30 times) than farm crops.

* Marine water in addition to brackish water is utilized for commercial growing of algae.

* Unlike petroleum fuels, biodiesel manufactured from algae are eco-friendly, thus reducing environmental pollution. In case there is spills of algae-based biodiesel in water sources, there are no long standing side effects on the ecosystem.

* Algae also sequester harmful Carbon Dioxide (C02), Nitrogen (N) and release Oxygen (O)

Studies show that about 60 percent of algae biomass can turned into biodiesel. The microalgae species are economically beneficial for biodiesel production over other larger algae species.

Co2 emission after using algal biodiesel is lower than those of petroleum fuels.

Since biodiesel production from algae is a recent technology, more research is required to cultivate standardized protocols for cultivation and large scale commercial algae biodiesel production. Commercial production on a large scale usually means 1million acres under cultivation. The most popular method of removing algal lipids is using an industrial oil press.

The development of the solar panel can be traced back to the 18th century when Horace de Saussare created the first solar collector. He built this in the year 1776, and probably could never have imagined how things would develop in later centuries. In 1861, this creation inspired the first solar power steam engine. This break through didn’t last very long but it did alert people to the potential of solar power.

As we move along the timeline to the 19th century we can see further developments. The 1880s saw the creation of the very first photovoltaic cells. This was a revolutionary discovery and it paved the way for the creation of the first commercial solar water heater. This was invented by a man called Clarence Kemp. Albert Einstein would later win a Nobel Prize for his work on photo-electricity.

It wasn’t really until the middle of the 20th century that you began to see solar power in mainstream usage. In the 1950s solar power was used to heat an office building. The solar power revolution was hit badly by economic reasons. People are price conscious and this means that with the fall in oil prices in the 1960s solar power usage fell out of favour.

The increasing prices of oil and global disasters such as the Gulf war have led to an ever increasing cost of oil. The push towards solar power continued and it is reported that in the 1990s over 1 million US homes had solar power panels installed.

In today’s world, solar power is used in two major ways: photovoltaic conversion format and thermal solar power. Thermal solar power is where the sun is used to heat fluids, which then powers turbines or other types of machinery. Photovoltaic conversion format is the basis on which solar panels operate. These panels are used to create electricity directly from the sun and can be used alone or in conjunction with other power resources.
