If you think solar power and solar batteries aren't the wave of the future, you may be missing out on some exciting possibilities. America is just now starting to take action in the way of policy changes and R&D funding to move away from energy produced from fossil fuels. On August 21st 2006, Governor Schwarzenegger signed the solar power bill that aims to make California the biggest producer of solar energy in the world by 2018 through the installation of 1 million rooftop solar batteries on residential homes, office buildings schools and farms.

Homeowners who outfit their homes with solar batteries will not only benefit from lower energy use costs and higher home resale value, but under Schwarzenegger's new law, they can sell excess power back to their utility company for a profit. Despite all of the evidence pointing to the positive aspects of power generated through solar batteries, including a commitment of $2.9 billion dollar commitment by the California Public Utilities Commission, many people still believe that solar batteries are ineffective for producing adequate power. In this article, we will explore the 3 most common misconceptions and facts surrounding home solar power and the solar battery.

Misconception #1 – I would need to live in a hot area of the country in order to benefit from a solar battery

There are two types of solar panels. One produces heat by absorbing heat from the sun. The other type, solar batteries, use Photovoltaic principles to turn the light from the sun into energy. These solar batteries are made of silicon which becomes electrically charged from the sunlight. The sun is always shining, even in the wintertime which means that solar batteries work year round-even when it doesn't feel hot outside.

Misconception #2 – Using a solar battery will not make that much of an impact on the environment

Unless you believe that reducing greenhouse gasses by 3 million tons for every 1 million homes equip with solar panels isn't a big impact, this misconception is simply untrue. The removal of 3 million tons of greenhouse gasses is roughly the equivalent of eliminating the harmful greenhouse gas emissions of 1 million cars. Multiply this by the total number of homes and residences in the US, and the impact is critical move for a growing population.

Misconception #3- Solar batteries cost more than they save

While it is true that solar batteries do involve more upfront costs than simply plugging into the grid, it's important to look at costs over the long term to get an accurate cost perspective. Solar batteries can continue to produce power steadily for 50 or more years. Once your batteries are installed and producing power, there are no more costs involved with taking energy from the grid. And while grid energy may be affordable now, that doesn't necessarily mean that it will be in the future. We have seen how quickly a limited supply and demand can impact the cost of gasoline.

What's more, if the rest of the US follows California's lead, excess electricity can be sold back to the energy for a profit. Solar batteries also open up new possibilities in home ownership; allowing people to build private getaways and vacation homes in remote, low land cost areas that are off the power grid. With the increased longevity and lower cost of today's solar batteries, homeowners owe it to themselves to explore the possibilities of solar power and to rethink their paradigms about energy costs and homebuilding possibilities.

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.

Douglas Taylor asked:

More and more people today are now looking for alternative ways of supplying power that they need in order to run appliances and equipment in their home. For some people because of where they live setting up a solar powered system is the ideal choice. In this article, we go through a number of factors that need to be taken into consideration if you are thinking about building a solar power system.

One of the first things that you should be doing in order to see if building a solar powered system is a viable option is to find out how much sunlight you get each day where you live. To do this you need to check out weather data for the area where you live or use a solar energy map, which you can easily find online.

The next thing that you need to do when considering building your own solar powered energy system is to calculate how much power it is you actually use. The easiest way of doing his by looking at the bills, you receive for your electricity company and then dividing the figures up so that they provide you an average of what you would use on a weekly basis. To work out what your weekly power consumption for your home is you take the total monthly figure off of your electricity bill and then divide this by 4.3.

Along with knowing how much sunlight, you are likely to get and how much power it is you will need to be able carry on running all appliances and equipment in your home there are other factors, which need to be taken into consideration. You need to make a decision on the kind of inverters you will be using, how many solar panels you will need and how many batteries you will need to store the energy in.

When it comes to selecting the inverters for your system, which is what converts the sunlight that has been collected by the solar panels in to AC power rather than DC power. All inverters will be rated according to their continuous and surge wattage. So the more power you are likely to use then the much higher these wattage ratings will need to be.

As for the batteries, you need ones that will be able to take continuous charges of electricity into them. Therefore, car batteries are not suitable simply because they are not designed to be able to collect and store large amounts of power at any time. The kind of batteries that you should be selecting to use when it comes to building your own solar powered system is say a marine or golf cart battery.

Of course, when it comes to someone actually choosing to build a solar powered system they must not forget about the solar panels. It is important that you carry out plenty of research on this item in order to ensure that you have the right ones for yours. As you will soon discover when looking for these panels there are a number of different sized panels to choose from. So take your time and look for those that will help to collect sufficient amounts of sunlight for your own particular requirements.

Kozsun Huseyin asked:

For many years man has utilized the raw products of Earth, which even though are part of Earth, the fossil fuels and gases being burnt, turns the Earth into a planet that looked like when it was uninhabitable for life as we know it. As we have entered the new millennium, a few of us, you and me, have looked for better ways.

Is it really possible to achieve all this with solar energy? I mean, imagine, imagine leaving your lights on constantly, and it does no harm to the world or your pocket!

You get your electricity bill, and get shocked that it is so high! There must be a better way! Wouldn't it be great if you could never see that electricity bill again, and still have power? What about leaving your lights on all the time, and it does no harm to your pocket or the environment?

The question really comes, is solar energy any good? Can solar energy really light your home, and give you all the energy you need to run your home? There are a lot of questions with solar energy; after all it is a technology not being grasped by many. However, more and more people are looking to solar energy to power the home.

One thing to keep in mind is that solar energy is not cheap. You need the solar panels, and some other equipment. Having solar energy also requires having a certain amount of light, so Alaska may not be the best place to install solar panels!

Having solar energy is much better then you might think. Even though the initial costs are high, some of the benefits of having solar energy to power your home is:

* Free electricity

* Cost of solar energy systems gets cheaper

* Zero emissions to the environment

* If everyone had solar energy, we would do major positive impact on our planets health

Homes which are constantly getting brownouts and blackouts can benefit from solar energy. You may be able to earn money, by selling your excess power to other homes or the electricity companies. And if you don't have enough power at the times of the year when there is not much sun light, you can get extra electricity from electricity companies, and your costs would be much lower.

Using your solar energy in your home over time has many benefits. Each year, each month, and each day more you use solar energy, you get to the point when you are actually getting into profit by having solar energy. The tax breaks can also be phenomenal, making solar energy an added advantage.
