Cathy Patterson asked:


In Europe and other parts of the world, solar power already is a choice many people have considered, and in this time of environmental issues it is something we all should be considering to. If we look at the world we live in solar energy is something we should take very seriously. There are two kinds of solar power solutions, you can join a power company who deliver solar electricity from a solar power plant or you can use residential solar power. In this article we will go over the advantages and disadvantages of residential solar power.

There are many advantages to home made electricity and just one of them is the environment, if you are also concerned about the environment but would like to educate yourself and understand all the pros and cons the best place to start is on the internet. Online is the place where you can get information about how to switch to solar energy and what you need to do so. There are a few forums you can visit where people can talk about all kinds of renewable energy and there are also websites that provide you general information about alternative sources of energy.

Renewable and non polluting

One of the advantages is that it is a renewable resource. The sun provides you with energy even on a cloudy day, off course it cannot be utilized at night but during the day there will be plenty energy you can harvest, and it is available for free day after day.

Another big advantage is that solar energy is a non-polluting form of energy. The fact is that you will not hurt the environment in any way when you use residential solar power. And there are so many ways you can use it. You can build a residential solar power system on your roof and you can use other products powered by the sun that are very affordable, easy to install (no wires) and that will never ask electricity from the grid again. A very good example are outdoor lights for security and to light up your yard. You just need to install it and you will not need much knowledge for that and your good to go. A solar powered light can be the first step before you move on to a complete residential solar power system.

Home made power can be a real money saver

If you look carefully at the calculations you will see that a residential solar power system is a large investment, but an investment that will pay itself back after a few years. And eventually it will save you a lot of money. But this investment will immediate save you money on your power bill and that is something that we all can use in these difficult times.

Are there any disadvantages?

Yes, and one of the biggest disadvantages to residential solar power is that the investment, the initial cost of such a system can be a bit much for most people. But, when you see the overall savings that you are going to make, the choice becomes a lot easier. It is important to inform yourself about all the pros and cons of residential solar power before you make a decision.

Wishing for Practical, Affordable Solar Power

Friday, March 13th, 2009

anonymous asked:


Solar power has been available for decades. Safe, relatively clean energy, but the cost of the panels has long been too high for the average consumer. They’re also the one problem with solar energy, for those wondering about the relatively clean energy part. But the recycling of them should improve over time.

Many people would love to go solar in their homes. It’s a practical energy source in many places, even ones where you wouldn’t expect it to do all that well. And in places where homes aren’t built near a pre-existing grid, solar power is often much, much more reasonable than having wires run out.

The fact that energy prices have been steadily rising also helps solar energy appear more reasonably priced. The cost is almost all upfront, which is perhaps the greatest challenge. A good solar power system sufficient to heat the average home in the United States runs many thousands of dollars. However it also offers tremendous savings over time.

Some people even generate enough excess to where they sell electricity back. It doesn’t bring in much money on the average, but you must admit that having the power company pay you has an appeal, especially if you aren’t paying them anything anymore.

Is solar power ready to take off at long last? It could be. We’ve been hearing for a long time that the day would come when solar power became affordable, something the average family could do, rather than something strictly for the affluent and environmentally aware.

States are becoming more interested in encouraging solar power as well. Many offer rebates or tax incentives to homeowners who install solar panels, and some are starting to look at businesses as well. May as well put those rooftops to good use, after all!

Unfortunately, not all states do this yet. It sounds like they will soon! There is federal legislation requiring states to consider adopting net metering standards by 2008. How this works from state to stat can be tricky, but since 40 states already have net metering, which allows customers to sell excess electricity back, paying only when they need more than they produce, things are looking better all the time.

Solar power is starting to fare better politically too. While it still lacks the funding of the coal or oil industries, it has popular backing. That does make a difference.

Choosing solar power still isn’t the easiest thing. As with other home improvements there’s a lot of paperwork, plus finding a reputable contractor with good solar panel installation experience. But things are definitely looking up.

An Overview: How Does Solar Power Work?

Wednesday, February 4th, 2009

Y.T. Lee asked:


Now that fossil fuels are becoming used up more and more with each passing day, the time for trying out another source of energy has come. One good source is solar power. At present, there are a number of people who utilize solar power not only in the workplace, but also in the home. How does solar power work, is a question that will immediately cross the minds of those who have not tried setting up solar panels to gain solar energy.

Most people who hear the phrase: ’solar energy’ will usually be reminded of the sun. Solar energy may be considered as the most practical energy source, especially because of the fact that it is renewable. Aside from that, it can be used in a variety of ways as it has different forms e.g. for heating purposes, for powering electrical appliances, etc. There was even a time during the 1980s wherein solar power was used to provide electricity to millions of homes in California.

Solar energy may be produced through the use of the so called photovoltaic tiles. Although there are other ways to produce this kind of energy, photovoltaic tiles may be considered as the most widely used. Photovoltaic tiles work by extracting energy from the sun which will be transformed into a purified form of electricity that can be used in homes. The said tiles are made up of photovoltaic cells, or solar cells that are comprised of negatively charged silicon and positively charged silicon. Once the protons of the sun meet with the silicon, an electric current is produced.

The electric current that results may be called direct current and must first go through an inverter. Once the said current passes through the inverter, it will be transformed into an alternating current which is what is needed to power electrical appliances in our homes. The resulting current may be less than 100% in terms of efficiency, but is still usable and will be able to bring down electricity bills significantly.

Another good thing about a solar cell or photovoltaic cell is that it requires very little maintenance and may even last for more than thirty years. With all the crises happening currently, solar energy is definitely refreshing and may be more efficient than other forms of energy.

Aside from providing power to a house, solar power may also be used as a heater. It can provide heat to a pool, give central heating, be used in boiling water, etc. A solar power system is usually so efficient that it can give between 75% to 100% power to the user’s property, with a significant part of that power brought back to the system or ‘recycled’. With this ‘power recycling’, the need to pay for electricity is lessened, thus creating more savings.

Many people who learn about the answers to the question: how does solar power work, may really want to try using a solar energy system in their homes. After all, who would not want to save money while at the same time have the electricity they need?

Solar Power Generator : an Eco-friendly Green Generator

Friday, January 9th, 2009
solar power
Pattrick Savarna asked:


A solar power generator uses solar energy to convert it into electrical energy in order to run the household appliances. Nowadays, one can easily see TVs, washing machines etc being powered by a solar power generator.

It is termed as “green generator” as it is a proven source of energy which adds nothing to the global warming and the atmospheric pollution. Rather it helps a lot to save the natural energy sources such as petroleum which are on the way of going extinct.

It is emerging as one of most reliable eco-friendly power generating devices. Its total inability to produce air-polluting smoke and irritating sound as other oil run generators do makes it special.A solar power generator is one of the best answers to the shortage of electricity.

A well optimized solar power generator helps a lot to minimize the soaring electricity bill as it is capable of running almost all the appliances merely using the free and unbound solar energy.

Moreover, this device is very user-friendly and needs least efforts while its installation. It is widely used in the countrysides and at those places where people face regular power crisis.

Like all other power generators, it too runs on a definite mechanism. The solar energy is concentrated on the solar panels only to produce DC ( direct current). Then this DC is converted into AC ( alternating current) using the solar inverter already present in the generator itself.

Apart from these two components, the third important components of a solar power generator are its rechargeable batteries. These batteries constantly keep receiving power from the inverter in order to run all the appliances.

The strength and efficiency of a solar power generator depends completely on how powerful its inverter is. It is the most important part of the generator as it has the capability to convert DC into AC. While buying an inverter, it is advisable to buy one which can produce a bit more energy than the actual demand of the home appliances.

In many homes it happens that there is hardly any appliance which is run buy AC. Thus those homes don’t need solar power generators with any inverters, apart from devices like DC input systems and DC meters.
