Photovoltaic Solar Systems: Advantages And Disadvantages

By Christopher Gilman

Today's high energy prices are ridiculous, and everyone should be looking at different ways to reduce energy costs. One good way to reduce energy costs is by using solar energy. Continue reading to find out some great advice about the advantages of using solar energy.

You need to read about and research where to place the panels. This can help you get a better idea as to where to place the panels on your own home after you've figured out how many you need. It's important to have a good idea as to where you want to put them, and of course you can ask professional installers any questions you may have as well.

Find out about grants and incentives that you may be eligible for. Both the federal government and individual states are now offering incentives to people who want to get solar panels and introduce solar energy. Therefore, it is smart to make sure you investigate as much as you can and apply for all the help you can get. While everyone agrees that it is very expensive to buy the large panels, it will be cheaper in the long run. Therefore, it is worth your time and effort to make every effort you can to put up the panels as soon as possible.

Sunlight costs nothing. On a good day, you have hours upon hours of free fuel pouring down onto your PV system at 186,000 miles per second. For most would-be consumers of solar energy, this is the most enticing benefit. Once your system is up and going, your source of power is free.

You won't have to own a huge home, but a sufficient solar system isn't going to fit on the roof of a small row house. If so, the government would have already installed them on their publicly funded projects, and they'd decree that the HOA must. The fact of the matter is that you need sufficient roof space to install a system that is quite large.

However, a single solar cell can barely power a flashlight, much less you home. That is why many of these small solar cells are wired together into solar panels, and these panels all work together to create the solar array that powers your home. The reason why you can even have a small solar installation in your home is because of this expandable property of solar energy. If you could only use a single cell to power a device, you would have to have a huge solar cell for each device in your home, which would simply be too cumbersome.

One way that you can harness the power of the sun without having to put thousands of dollars toward solar panels is by purchasing small outdoor lamps that utilize solar power. While this may seem minuscule, it is a cost effective way to light the outside of your home during night and it is a way that you can begin to be more conscious of the environment.

Remember these tips and do more research about solar power. Stay up to date with innovations in this field; new products should appear on the market and make solar power more affordable in the next few years.

Solar Power for Homes Is Main Stream Now

By Joe Johnson

Solar power for homes has come a long way since the boxy design of the solar panels most of us are familiar with. Tremendous advancements have been made in solar cell construction that allow many building materials to be manufactured with the solar cells incorporated into their design effectively turning them into virtually undetectable solar panels.


Solar power for homes is supplied through one of two systems. The first is a stand alone solar power system that functions as your sole source of electricity. The other type is a supplemental solar power system which can supply all of your homes electricity depending on sunlight availability, and can utilize the power company grid when solar power is not available.


The basic components to generate solar power for homes are the same whether you opt for a standalone system or a supplemental system. First you have the photovoltaic panels, commonly known as PV or solar panels, these panels are lined with a semi conductor or solar cell that turns the rays of the sun into electricity. This electricity is then routed into a regulator/controller that keeps the current at the voltage/amperage level your system is designed for. The electricity is then routed either into your homes electrical system or into a battery array or storage system that will keep that solar power available when the sun goes down.


As long as your house is hooked up to the power company's grid, you won't need to set up a separate storage system. However, setting up your own storage is more advantageous as your monthly utility bill be reduced further and you'll still have power even during an outage.


Supplementing or replacing your electricity needs with solar power for homes is becoming easier and more affordable than ever. Some building materials include roofing material, awnings, car port roofing and the edges of the panes in your windows. This type of solar panel is called Building Integrated Photovoltaics. When used in roofing material these panels offer the same level of home protection as asphalt shingles while functioning as a solar panel.

The set-up cost of converting to solar power for homes s the real disadvantage, as it can be quite expensive. But there are some things you can do about that. State and federal grants are there to assist you in setting up an alternative energy source for your home, taking some of the financial weight off your shoulders. While the federal rebate might vary from one year to the next, state rebates vary from one state to another; some states offer special low-interest financing as an additional incentive of the green variety along with any rebates.


Besides the fact that you'll make your home greener using solar power for homes, you'll also be seeing lots of "green" with all the savings on your utility bill. You may even be able to eliminate a utility bill altogether. A growing number of utility companies now have a metering program allowing you to sell to the power company any excess power produced by your solar power system. It certainly pays to go green!

Solar And Wind Power Generation

By Adrian Fletcher

Solar and wind power in the home are probably the most widely used forms of alternative energy. When used in conjunction they form a totally green, round the clock hybrid energy system. They can even be wired into the utility grid connected system to supply the majority of your energy needs while the utility company functions as your backup energy source.

A solar power system will supply electricity generated by the rays of the sun. Solar panels lined with a semiconductor which generates electricity whenever the rays strike it can be installed either using a roof, pole, or ground mount. Such mounts are usually equipped with motors which let the panels be tilted during the course of the day so they can follow the sun's path.

The electricity generated by such systems is routed through a regulator/controller and then to an inverter to change the direct current to alternate current. Depending upon your installation, it may be sent to your battery array as direct current or to the electrical system in your home. When it is passed to your home, it can be used to power all your appliances just as the electricity from the grid may be currently doing.

Creating electricity is the same when using a wind power system, except that it is generated in the body of a turbine. The turbine is the huge, fan-like part with blades at the top of iron towers we sometimes see on hillsides.

In a wind power setup the wind turns the blades of the wind turbine the shaft of which is routed into a generator which as it spins creates the electricity. That electricity is then routed into your structure's electrical or storage system to provide power on its own or as a backup to your solar power.

With wind power, the most significant cost is the wind turbine. Still, the turbine will be more inexpensive than the total solar equipment you'll be required to purchase. The downside is that the turbine must be located in a spot far off the ground, usually needing to be mounted on top of a tower of some sort which can be expensive. The installation of solar power will probably require zoning authorization from the municipality and significantly more planning.

When you connect a solar power system with a wind power system, each part can operate in tandem to compensate and complement each other. Wind power can be produced at any time while solar has its natural limits based on the hours that the sun shines and bad weather. Conversely bad weather for a solar system maybe good weather for a wind generator. Both these systems can be built quite cheaply depending on the amount of power you want to create. Some guide suggests this figure could be as low as $400. However a professionally designed and installed system would cost much more than this.

Solar Power For Homes

By Adrian Fletcher

Solar power for the home has made great strides since its early beginnings. Technological advancements have allowed commercially available building materials to incorporate solar cells, which turns them into solar panels that are virtually invisible to the naked eye.

There are two ways that solar power for homes is supplied. These are off-grid and on grid or net metering. A stand alone solar power system acts as the sole source of electricity for your home and is off the grid as such. Alternatively, supplemental solar power systems, can supply all of your homes energy depending on sunlight availability. When sunlight is not available, your home can use energy from the power grid.

Standalone solar power systems and supplemental systems for the generation of solar power for homes contain the same fundamental parts. At the outset are the photovoltaic panels, generally referred to as PV or solar panels, which are equipped with a solar cell or semiconductor that transforms the sun's rays into electricity. The electricity then is routed to a regulator/controller which maintains the electric current at the voltage/amperage level the system is made for. Electricity then is routed into your home's electrical system or else into a battery array or a storage system which will keep the solar power ready for when the sun sets.

If your home is connected to a power company grid you do not have to install a storage system, but it does have its advantages as it will help to further lower your monthly utility bill, and it will make power available to you during a power outage.

It is now cheaper and simpler than ever before to reduce or eliminate your need for outside electricity by using solar power for homes. Several types of building materials include awnings, roofing materials, car port roofing, and edges of window panes. This kind of solar panel is known as Building Integrated Photovoltaics. If used for roofing material, such panels provide the same measure of home protection as do asphalt shingles, even while they function as a solar panel.

One of the greatest obstacles to using solar power for homes has traditionally been the up-front expense. Now, however, there are avenues to offsetting that expense. Government grants are available which go a long way toward subsidizing your household's conversion to solar power. Federal rebates for solar power installations can vary year from year, and each state that offers one has its own incentives ranging from additional rebates to offering low-interest rates to finance green projects.

Besides the fact that you'll make your home greener using solar power for homes, you'll also be seeing lots of "green" with all the savings on your utility bill. You may even be able to eliminate a utility bill altogether. A growing number of utility companies now have a metering program allowing you to sell to the power company any excess power produced by your solar power system. Selling your excess electricity to the power company is a good idea and more net metering programs will be enacted in various states in the future. An incentive to sell your electricity to the utility company benefits other people that can use the power and reduces the utility companies need on coal and other fossil fuels to generate electricity.

Do We Need To Find Alternative Sources of Energy?

Is there really a need to find alternative sources of energy? I believe there is. The problem we face is figuring out how to tap into the renewable, natural resources we have. The pollution from using fossil fuels and from nuclear waste is going to have consequences to us and to our environment. Just what alternative energy sources are available?

Solar Energy

Solar energy is just energy from the sun that is converted into electricity using a process called photo-voltaics. Solar power has been used for quite some time and can give us electricity for homes and buildings. It can also be used as fuel for vehicles, for solar cookers, in metal smelting, and to make industrial chemicals.

Hydroelectricity

Hydroelectricity is the most commonly used source of alternative energy. This type of power is made by utilizing the gravitational force of water falling from a high place. Here's the good news; hydroelectric plants do not create toxic by-products and don't emit many greenhouse gases. Dams can be expensive to build and maintain, but the benefits of a hydro-electric plant outweigh the cost in the long run.

Wind Energy

Energy that comes from the wind is renewed each time you use it and won't cost you much at all . Wind power can be used in agriculture to pump water or grind grain. We can harness the power of the wind to run our homes and the various 'gadgets' we seem to have so many of.

Geothermal power

Heat from below the earth's surface produces geothermal power. From an economic standpoint, this form of energy is more feasible than using fossil fuels that have rising costs. One large geothermal plant could power a whole community. Geothermal plants run a lot cleaner and don't release a lot of poisonous gases into our air.

These are the more common and environmentally friendly alternative energy sources. I think we need to explore these options and implement them as much as we can.

Alternative Energy Sources

Alternative energy sources may be one way we can stay ahead of the rising costs of energy. I don’t see these costs going down anytime soon. Are you tired of paying more every time you turn around? I sure am! What else can we do? One thing I have been doing is exploring how I can use more renewable energy sources and other ways to have a ‘greener’ lifestyle.

It used to be that alternative energy sources for your home such as wind power or solar power were so expensive that the average homeowner couldn’t afford to have them installed. Many people have looked into the cost of solar panels and ran away screaming when they see the cost! Fortunately there are step-by-step instructions available now for the homeowner to convert over to solar or wind power at a fraction of what it used to cost them.

The amount of energy we use in our homes is at an all time high. Some people are very frugal with their energy use, while others don’t seem to care if they waste electricity or gas. I have decided to save myself some money and use more alternative energy sources around my house. From what I’ve learned, it can save me at least 50-80% on my fuel bills. That sounds pretty good to me!
