In the United States, more than 10 thousand homes and businesses are powered solely by solar systems. On top of that, several hundred thousand homes and businesses use solar energy units for their energy requirements. That results in substantial savings on electricity bills. Respectively, the use of conventional resources (fossil fuels, etc.) is decreased, which results in less environmental pollution.

The installation costs for a home of a typical family can be $18-20 K if carried out by a professional contractor. Such high costs prevent families from using solar energy units. However one can save on installation through tax credits and state rebates. Besides, if you do it yourself, the cost would be only about 30 % before tax credits and rebates.

You can have a couple of choices: a stand-alone unit that requires battery or a grid-intertied unit.

A worthwhile improvement to your house would be to convert to grid-intertied solar energy unit. Planning ahead is the main prerequisite of successful conversion.

First, calculate the amount of energy you will need based on historical consumption data. You need to choose the right size of your solar energy unit. An oversize energy unit will generate more energy which you could send to the power company, but you can only get credit and not cash for it.

Next, determine whether your house is suitable for a solar system. The factors to be considered are as follows: available space, house location and climatic conditions. A rule of thumb for estimating required roof space is 80 to 100 sq. ft. per kilowatt. A house should face south for the solar panel system to be efficient, and should be free of objects that may obstruct sunlight.

Though it is possible to install the solar panel units on poles, solar panel systems are as a rule mounted on the roof. Using steel bolts, the mounts are attached to roof rafters. The panels are then installed on the frames.

Solar panel kits are readily available in the market. There are suppliers that offer their panels on the Internet, but it is not recommended to buy from them unless you have experience with installing them.

Typical set of hardware you will need for a batteryless grid-intertied system consists of: solar panel units, power inverter, power meter, roof mounts, a couple of heavy duty safety switches, wires and cable trays. A DIY kit for a 1-kW system would cost a little over $3,000.

If you don’t have prior experience in this area, you are to choose a respectable vendor who is known for outstanding service. It is prudent to purchase DIY kits with an installation manual that at least has an adequate number of illustrations. The vendor should preferably have contact telephone number, and much better, could send a representative in case you run into a problem with installation. Alternatively if you are a lucky guy and have a friend or acquaintance who has experience with installing home solar energy units, then ask him to assist you in the purchase of the hardware as well as in the installation.

Many individuals have shown that renewable energy can save you money and the environment. With the variety of improved, inexpensive solar panels for homes and businesses, solar electricity is the best option for most of us, so start that home improvement project: install a solar panel system for your home.

Use of Solar Panels For Household Purposes is a post from: Residential Power

Solar panels for home use can also be used to heat up water, saving you money. In colder areas, where the water table temperature is less than 60 degrees, using solar can heat up water to a higher temperature. This could result in relieving some pressure on water boilers, because it wouldn’t take long to heat up water. For ambient temperatures above 60 degrees, and where you have sufficient sunlight, you should be able to get rid of your heater entirely. Even just heating your shower water can reduce your heating costs by up to 40-60%. Instead of solar systems having a photovoltaic cell array, one will be able to utilize the ones that have pipes running inside their frames. When the water goes through, the raise temperature of the water (more or less based on the type of piping used). If this water is pumping through consistently before feeding into the hot water supply system, it will be warmer.

Home solar systems are able to do way more than just be used for heating your water supply and producing electric power. Solar systems help to save the environment. On the one hand, they use energy that is abundant, renewable, and totally free for all people to benefit from. Generating electric power from the sun doesn’t necessitate the use of our natural resources, and these panels don’t produce any harmful emissions. Regardless of whether you are still connected to the grid, or fully self sustained, using solar panels can help reduce your energy consumption. This will decrease the load on power plants, many of which still burn fossil fuels such as brown coal and petroleum products to create electricity.

With the right solar panel power system in place, not only will it pay for itself in a short space of time, but it will actually make you money. How will it make you money? If your solar system is hooked up to your grid still, and you generate more electric power than you can store and use, it goes directly back into to the grid. In essence, you become a small-size power plant, and in accordance with the law, utility companies are to buy this surplus power from you. You shall make arrangements beforehand, but even twenty dollars per week is better than making nothing at all.

As a rule, the majority of people who use solar panels for homes will stay connected to the main power network just to receive extra income. In closing, not only can solar systems be used to save you dollars when paying your bills, but can also be turned into an additional income source.

What Home Solar Systems Can Be Used For is a post from: Residential Power

In America, more than 10 thousand homes and businesses are powered entirely by solar panel systems. On top of that, 200,000 homes and businesses use solar energy units for their energy requirements. That results in significant savings on electricity bills. Subsequently, the use of conventional resources (fossil fuels, etc.) is decreased, which leads to less environmental pollution.

The cost of installation for a home of a typical family can run $18,000-20,000 if carried out by a professional contractor. These high costs prevent families from using solar energy units. But anybody can save on installation by applying for tax credits and state rebates. Also,you can do it yourself, and then the cost would be only about 30 % before tax credits and rebates.

You can have 2 choices: a stand-alone system that needs battery or a system that is tied to the grid.

A worthwhile improvement to your home is to convert to grid-intertied solar panel system. Planning is the main prerequisite of successful conversion.

First, estimate the amount of energy you need based on historical consumption. You should select the right size of your solar panel system. An oversized energy system will produce more power which you could sell to the power company, but you can only receive credit and not cash for it.

Next, determine if your home is suitable for a solar system. The factors to be considered are as follows: available space, building orientation and climatic conditions. A good estimate of roof space is 80 to 100 sq. ft. per kW. A house should be oriented towards south for the system to be efficient, and there should be no objects that may obstruct sun rays.

Although it is possible to mount the solar panel units on poles, panels are as a rule mounted on rooftops. Using steel bolts, the frames are attached to roof rafters. The solar panels are then attached to the supports.

Solar panels are readily available in the market. There are suppliers that sell their panels on the Internet, but it is not recommended to purchase the kits from them unless you are an experienced DIY solar panel kit builder.

Typical set of hardware you need for a stand-alone system without a battery that is tied to the grid consists of: solar panels, utility-interactive inverter, power meter, roof mounts, a couple of heavy duty safety switches, wires and conduits. A DIY installation for a 1-kW system would cost a little above the $3,000 mark.

If you are not experienced in this area, you ought to pick a reputable supplier who is known for excellent service. It is prudent to look for DIY kits with accompanying installation manual that at least has enough illustrations. The supplier should preferably have contact telephone number, and better yet, could provide a representative in case you need advice. Alternatively if you are a lucky guy and have a friend or acquaintance who had experience with installing home solar energy units, then ask him to lend a hand in the buying of the hardware and in the installation.

Solar Panels For Home And Business Purposes is a post from: Residential Power

Solar cells are the components that actually turn sunlight into electricity. If you know what type of power you require, you can get started, as solar cells, depending on how they’re connected, can output virtually any amount of voltage and current.

The two standard kinds of solar cells available provide different levels of performance. Monocrystalline solar cells offer the highest level of efficiency currently available. Thanks to its unified construction, a monocrystalline cell will be very durable in addition to generating power at such a high level of efficiency. Although they cost a bit more, monocrystalline cells tend to be a superior value over the long term because of their durability. The other common type of solar cell is the polycrystalline cell. Polycrystalline cells are less expensive, but they don’t produce as efficiently as monocrystalline cells do.

The next step is to connect the solar cells together, making sure that it’s done in such a way that the required voltage and current will be generated. Wiring diagrams are part of the majority of DIY solar panel blueprints. It’s important to follow the diagram as closely as possible. You need to make sure that the solar cells will all be facing the exact same direction; this can be accomplished by mounting them on a piece of thick plywood. The required size for the backing board can be seen by laying out the cells as shown in the wiring diagram. Refer to the diagram again once the cells have been mounted; you can now begin the soldering. The wires need to be secured neatly to the backing board so that they don’t block any sunlight. Once this has been done, take the panel outside and check the voltage with a meter to make sure that everything is as it should be. Check your wiring if there are any problems. To complete the solar panel, add sides and a clear front part to the backing. Use weatherproof caulking to ensure that the enclosure is tight enough to withstand the elements.

Now, you can mount the panel in a spot that sees lots of sun exposure. The DC electricity generated by the panel can be used to charge batteries or power some small appliances. Connect your system to an inverter to obtain AC power, which is used by the majority of devices in the home.

Solar Panels for Homes is a post from: Residential Power

A solar panel is a devise that takes the inherent energy of the sun and turns it into electricity, which we can use to power the appliances in our homes.

Solar panels are made of many smaller units called solar cells. The purpose of each of these cells is to take the energy from the sun and, using a miniscule reaction, release that tiny amount of energy in the form of an electron that can then be combined with other electrons to form an electrical current.

Algae that live in the oceans of the world have been making solar panels for millions of years. They don’t need the volume of energy that we want, from our solar panels, but they make them from the materials immediately available to them.

Scientists many years ago discovered that if you put certain chemicals together in a container and then put that container out in the sunlight, that the energy the sun gives off will change the makeup of the chemicals by releasing electrons. The electron is the functional unit of electricity. The energy that powers all our wonderful technology is a steady and massive stream of these tiny electric particles.

Scientific advancement has made it possible to maximize the efficiency of solar technology. The current technology now refers to these chemical reservoirs as solar cells. Each solar cell depends on its own chemical makeup to cause the suns energy to release electrons.

The solar cell that releases an electron is combined with others and they are connected to others, and so on, until enough of them are strung together to provide a sufficient current to be used to power what we want. This collection of individual solar cells, in whatever volume is required, is called a solar panel.

If more energy is needed, these solar panels are then combined to produce a solar array.

So you see all you need to do to make a solar panel is to find the right container and fill it with the right combination of chemicals and expose it to sunlight. Then you can link these cells together, to form a panel and link the panels to form an array. The only thing really missing from this is the right equipment, material and the knowledge. Being handy would probably help too.

If you want to be able to make a solar panel you will need to find someone who has the knowledge and convince them to share it. Remember that the very first solar panels were made from material available at the time. There weren’t always mass produced off-shore solar cells available. Someone invented them. Someone else improved them and invariably someone will probably perfect them.

Naturally, the costs can be considerable, and perhaps you don’t have a lot of money to invest. You will be able to learn how to make a solar panel. You can learn to tie an array together and you can make your own free energy from the sun.

One of the aims of this site is to provide you with the options and recommendations to find and source the information you need to be able to make a solar panel now.

Make a Solar Panel, Easy DIY is a post from: Residential Power

The price of electricity is going up. The price of everything in our capitalist society will go up. Inflation affects all nations and economies and as a nation the way we deal with it will determine our results on how we will grow and prosper. This problem has made us look at the use of alternative energy sources such as home solar panels and windmill generators as a means of saving money and improving our environment.

The old generating systems for power are destroying the world we live in. Everyone knows that the environmental crisis is one of our making. The only way out of this situation, is for us, as individuals and as a nation, to spearhead the two pronged movement to reduce our energy consumption and develop alternative energy sources that are not damaging to our world.

As a nation, our leaders have taken the initiative and put significant financial resources into home solar panels technology, wind and nuclear energy. Wind and solar power harnesses existing natural resources to produce energy, with little adverse effect on the environment.

Due to government investment in these renewable technologies, it has allowed the research to move quicker, resulting in lower prices and smaller scale for the home user.

The concept of a small wind turbine and/or a solar array has come full circle, to be seen as a reasonable and rational concept for main stream society.

The technology of solar power – familiar to students of physics — works by exposing solar photons to thin sheets of different electric elements, producing an electric current. With a sufficient number of these panels, it is possible to power your home. It is vitally important that we as a nation must adopt a new way forward in our use of our resources such as our energy and power needs if we are to survive in the coming years.

It is vital to streamline appliances in order to maximize their efficiency. It is an achievable goal to expect self suffiency in the future if we keep our efforts to spread the awareness at all levels of society.

For those in areas without constant sunshine, it is possible to utilize wind turbine technology to produce power to supplement.

A good option to help in climates where solar energy is restricted due to climate limitations, is the geothermal or aqua thermal heat pump. Already becoming extremely popular in the cooler climates, the ‘heat pump’ transfers the inherent heat of the Earths average 65 degree constant temperature, into a system of liquid filled pipes, and, with the use of a refrigerator-like compressor, send it into your home. It even reverses to cool in the summer.

If this heat pump is powered by your home solar panels, you have succeeded in making your solar panel installation part of the solution to our environmental problem.

Solar Panels for the Home is a post from: Residential Power

To be eco-friendly, or gentle on the environment, means a couple of things. The first thing in my view is to create a good environment inside the house by using sound construction materials. You don’t want to introduce some toxic stuff in your home. For example: formaldehyde – a very dangerous compound – is found in certain types of particle board. Formaldehyde fumes make you really sick, even in low concentrations.

Another thing to look at is the heating system. In the area where I live, there was a time when the cost of electric power was very low. Guess what – everyone figured they should use electric heating in their dwellings. As far as I understand it, this solution isn’t used much these days, as the electricity cost has increased a lot.

Same thing with oil. Fifty years ago, the price of oil was very low and therefore everyone used oil for heating their house. Today, this is getting very costly due to rising oil prices.

If you insulate your house better, you can beat the mounting costs of energy. During the happy days of cheap energy, houses tended to be built with poor insulation. Back when oil was so inexpensive, spending cash on insulation was seen as useless.

Things have changed nowadays. Insulating your house better can cut your energy bill in half in some cases. Believe it or not, there are super.insulated houses that hardly need any extra heating. Conclusion: investing a bit in extra insulation is likely to save you money over time.

Ideally, you’d want a solar powered house. Suppose you could turn all the sunlight which falls on your house to useful energy – then you wouldn’t need any other source. It would be enough to run your (electric) car also.

In practise, this isn’t possible today. However, some experimental solar cell designs have reached an efficiency above 40 per cent. Nearly half the sunlight converted to electric power, in other words.

Of course, these cutting-edge solar cells are still very expensive. But solar panels with more modest efficiency are mass-produced, and getting fairly inexpensive. Nowadays a number of manufacturers are producing photovoltaic cells with up to 20 per cent efficiency, using streamlined methods like continous printing.

If you want home solar panels you can also save money by assembling them yourself. Just like with most home improvement projects, doing it yourself cuts costs.

And apart from the cash savings, you also have the satisfaction of being able to do your own thing.

Once installed, solar panels for homes typically are expected to last for over 20 years. So even if they cost some money upfront, you save on the utility bill in the long run.

How I Imagine the House of My Dreams: Solar Powered is a post from: Residential Power

Although the benefits have been tremendous, we also see a number of problems. The coal and oil we burn is really nothing but ancient sunlight. As we use these very ancient stored energy sources, they end up in the air in the form of CO2 = carbon dioxide. Naturally, the air then gets to contain more of that gas.

One property of CO2 is that it although it transmits visible light, infrared radiation is reflected. This means that when the CO2 level goes up, more infrared radiation is trapped near the Earth’s surface.

There was a period in the history of the Earth, hundreds of millions of years ago, when most life went extinct. It seems that this mass extinction was associated with a sharp increase of carbon dioxide in the air. This would have caused the surface of the Earth to become much hotter.

A sharp rise in the concentration of CO2 in the atmosphere has already happened – correlated with the use of fossil energy. Further, the climate is clearly getting warmer than it used to in a number of areas. It is especially the polar caps that are melting at an alarming rate.

My feeling is that we need to take action now if we care about our children and grandchildren. The question is: what can be done by you and me? One thing we can do is try to minimize the use of things like coal and oil. Rather, we could utilize renewable energy sources.

Ultimately, most energy sources are derived from the sun. Suppose that energy is collected directly – then we get rid of several problems. How about solar panels for example.

There is nothing new about solar cells, they’ve been produced for many years but have been very expensive. Therefore, they have not been a feasible energy source for general use. This is changing now; solar panels are getting affordable. Why not set up home solar panels on your rooftop and reap the benefit of clean solar energy. With some do-it-yourself work, you can bring down the cost even more. Being able to live off the grid – how about that.

Of course, it partly has to do with the general crisis in the economy. Yet there is another aspect, namely the global warming. Many folks hesitate to throw their money on buying a gasoline-powered vehicle.

I am sure we will soon see a breakthrough for electric cars. There is really only one weakness with electric cars: batteries haven’t been powerful enough. However, more efficient batteries are in the works. And once you get these into production, there is no reason to buy an old-fashioned gas-powered car.

By the way, the energy efficiency of an electric car is far superior to the efficiency of gas-powered vehicles. One of the reasons for this is that an electric engine works only when it really needs to. Such an engine doesn’t need an “idle”, for example.

Imagine that most cars are now running on electricity instead of gasoline. OK, you don’t need to be Einstein to realize this is going to mean a greater demand for electric energy. And I guess none of us wants to get a higher utility bill? The answer is: get independent, get solar power! Solar panels for homes are the best thing since sliced bread. Photovoltaic panels can be set up on the roof of your house.

And then your house and your vehicle are both solar-powered. There is no pollution and once the system is set up, the rest is a free ride.

You may think that this will be something very expensive to install. Well, that used to be the case but not anymore. The cost of making solar cells is going down rapidly. Everyone knows that there is a huge demand for cheap solar power products. Therefore several companies are working hard to make them.

One company, Nanosolar, has found a way to make solar panels in an assembly line process. The process is a bit like printing newspapers. A semiconducting material which looks like paint is sprayed on to a metal foil. This is a very fast and easy process once set up.

Imagine the enormous potential of using rooftops to collect solar energy!
