How Does Solar Power Work?

February 11th, 2010

Solar power became popular when it was first used in calculators where solar cells are used instead of traditional batteries. There were watches too that used solar energy and the advantage of not using batteries created long term savings. Today, solar energy is not only used in these gadgets, the use of solar energy is already possible to power any household. Gardens and pools can also use solar power as a source of electricity for hydroponics or heating, respectively. The reality is here that anybody can take advantage of solar power for the home and contribute to making the environment cleaner and better.

Solar power started with big solar panels installed in California supplying more than 10 million homes in the state. Today, the technology has evolved into more compact and smaller panels that can supply even more homes.

Basically, solar energy is used to derive electricity from sunlight. This can be done directly or indirectly through photovoltaic or through concentrating solar power, respectively. The use of photovoltaic converts the energy coming from the sun and converts it into a clean form of electricity that can power houses. These photovoltaic cells are composed of both positive and negative slices of silicon placed under a thin glass. When the protons of the rays of the sun hits the photovoltaic cell, the neutrons are knocked off the silicon. These neutrons become stored through the magnetic field and are connected to a circuit that forms electric current. Consequently, direct current electricity is generated and the process includes converting the DC into alternating current that is supplied to homes that can power all electrical appliances.

In the conversion process, not all of the converted electricity are caught in the process. There is a small percentage that is lost. But the percentage converted is already enough to supply the electricity needs of homes.

The good thing about using photovoltaic or PV cells is that there is no requirement for maintenance. Since the cells are static, which means there are no machines or moving elements in the system, the cells can last for four decades. The only requirement is to clean the cells annually and everything is considered properly maintained.
Solar power is very useful in household operations. With a grid tie system that you can set up in your home, you can enjoy the benefits of solar power that can help in your electricity needs. With a good roof space, the installation is easy and when you generate more electricity compared to what you need, you can even sell the electricity back. This can mean that you will no longer have to pay for your electricity.

The use of solar power will give many benefits to you and the environment. It is time to consider the installation in your home to contribute greatly to a cleaner environment not to mention the financial impact that it can give to your budget. This is a wise move and with the technology available, there is no reason not to take advantage of this during these trying economic times.

All You Want To Know About Solar Panels

February 10th, 2010

No one has a doubt that our planet is facing all round environmental degradation due to human intervention. However, there is a growing realization now that all this needs to be stopped and reversed. Hence, there are ways to find out about the eco-friendly, green, sustainable, alternative and renewable energies and technologies, which can contribute to make things better. There is a strong belief that the technological innovation and intervention in renewable sources of energy like sun, wind, ocean thermal gradient, tides, etc. can help us out in this situation. Out of these, the solar energy is, perhaps, the most important.

The utilization of the solar energy is currently being done by two technologies:

a) the photo-voltaic technology, and

b) the solar thermal technology.

The photovoltaic (PV) technology is used to make solar panels and it involves the conversion of solar rays into electricity which, in turn, is used for running a variety of electrical appliances. The thermal technology, however, directly converts the solar rays into power as in solar cookers.

PV solar panels come in three types of thin film varieties: mono- crystalline, multi-crystalline, and amorphous. A PV cell is made up of one or more layers of semi-conducting material, which is more often silicon, an expensive but indispensable proposition. On reception of sunlight, an electric field develops across the silicon chip layers resulting in a flow of electricity. Normally, two designs of panels are available, flat-plate and concentrator. The PV Solar panel can produce some electricity even under cloudy conditions. The intensity or strength of PV cells is measured in terms of kilowatt peak (KWP). Thin films cost less to produce than silicon cells as they are made up of wafer thin layers of photosensitive material, and the manufacturing process consumes less energy. Thin films can be embedded in roof shingles, windows, and sidings.

The solar panels can be installed on the roof tops of the buildings that do not come under the shadow of any other building or something else. They should preferably be south facing. The panels are mounted on poles or platforms and cover considerable area.

Before opting for this type of technology, a reasonable assessment of the power requirement shall be made. The cost-benefit analysis shall be done duly considering expenses like the initial capital outlay, installation, and regular maintenance cost of the solar panels, the benefits like the tax credits and subsidies from the government, savings from the monthly electricity charges, etc. Social and environmental factors like reduction in pollution, reduction in global warming, dependence on fossil fuels, etc. shall also be considered. The benefits far outweigh the costs in the long run.

These panels can be used to run a variety of appliances at home and at commercial establishments like the bulbs/CFLs, solar geysers, solar cookers, water pumps, fans, traffic signals, heating and cooling systems of the building, etc. However, it shall be noted that the panels function best when these are utilized optimally, which means that these are not used to run high-wattage appliances if the installed capacity is less.

To top it all, the electricity generated by the alternative renewable sources of energy including the solar panels can be sold to the power company and this means generation of regular income for the individual. So, these have earning potential as well.

How To Build Your Own Homemade Solar System – Step By Step Non Technical Instructions

February 10th, 2010

One of the biggest household expenses is the electricity bills. The amount you pay for power is next to the bank home mortgage. Many home owners are looking into using solar energy to supplement their home energy needs.

A complete system installed by a professional contractor can be quite expensive. Be prepared to invest upwards of $30,000 for a home solar system that may take up to 20 years to recoup.

Is there a cheaper option?

As a matter of fact, you can build your own residential solar power system with a budget of about $1500. With that kind of budget, you will be able to setup a small solar system which is capable of powering most of the electrical appliances and all of the lighting fixtures.

Where do you start?

Begin by figuring out how many electrical equipment you want to be powered by the solar system. Items such as television, computer, stereo, hair dryer etc are suitable. Leave out energy hungry appliances such as the refrigerator, micro wave oven, vacuum cleaner etc. These will create too much strain on the system.

The next step is to calculate the total power (wattage) required. Look at the back of the equipment and there should be an average power usage of the device. Look at the power consumption of the lighting fixtures also. Add up all the figures and that will be your energy needs base line.

The next step is to begin shopping for the solar parts and component. The following are the key components you will need:

1) Solar panel.
2) Charge controller.
3) Battery bank.
4) Power inverter.

The function of the solar panel is to convert the sun energy into electricity. When shopping for a solar panel, look for a unit which is capable of generating at least 12 volts of Direct Current (DC).

The power from the solar panel will be directed into the charge controller. The function of the charge controller is to regulate the battery charging process. When the battery is fully charged, it will dump excess power into a heat element, hence protecting the battery.

The type of battery suitable for a home solar power system is the deep cycle kind. Deep cycle battery is more robust and can handle a deeper level of power discharge without destroying itself.

How many batteries do you need?

It is hard to determine the exact figure because you can’t really know how much sun coverage you will get on a daily basis. A good number to begin with for a small home solar system is 4 units.

Finally, it is the power inverter. Since the battery can only hold Direct Current (DC), we have to change it into Alternative Current (AC). Most of our household appliances run on AC.

Remember the total power wattage you calculated earlier? Make sure the power inverter has an output above that figure. For example, if your total power need is 500 watt, choose a power inverter which is capable of producing at least 1000 watt.

At the end of the day, all the components will cost you around $1500. The total cost can be lowered if you were to spend the time looking for bargains.

Will You Extremely Slash Your Power Bill Using Solar Energy?

December 21st, 2009

Everybody’s talking concerning solar energy. With all the excitement, you’d think we have a tendency to just discovered the sun. After all, the sun has been around for a few billion years and, surprisingly, therefore has solar energy. We simply haven’t done a lot of with it till lately.

Generating electricity from the sun is not very complicated. Of course, it doesn’t require an enormous monetary investment or any special knowledge which will’t be picked up by reading the proper material.

How Solar Energy Saves YOU Money

If your home is connected to the general public power grid, you pay your electric utility company for the amount of power you use every month.

Really, if you look at your bill, you will in all probability see that as well as paying for electricity, you’re also paying fuel surcharges and any number of native, county, state or federal taxes. Add that each one up and electricity will take quite a bite out of your monthly budget.

The U.S. Department of Energy publishes annual average electricity costs by state. These costs are displayed as a range of cents per kilowatt hour (kWh). The actual definition of a kilowatt hour is not important, but how many kilowatt hours you consume every month is.

Here are some typical usage examples for electrical appliances and devices you probably have in your home:

* A 1000 watt space heater uses 1 kWh hour for each hour you run it
* A 60 watt light bulb uses 0.06 kWh
* A 12000 BTU AC unit uses three hundred kWh
* A central AC unit uses 900 kWh
* A dishwasher uses thirty kWh

It is simple to work out that every kWh you are taking off the grid and replace with solar energy saves you real money.

Need To Get Paid For Generating Solar Power?

Not solely can you slash, or even eliminate your power bill by converting to solar energy but, depending upon where you live, your local utility company may truly be required to buy the excess energy your solar system generates above your actual monthly consumption!

So, How Do You Get Started Slashing Your Electric Bill?

Check your monthly electric bill and see how several kWh you are billed for. Then use this formula to spot the particular kWh usage of everything you plug in:

kWh = watts/a thousand

As an example, a PC and monitor consumes 365 watts thus 365/one thousand =.0365 kWh. If you employ your PC for 75 hours per month, it consumes 27.4 kWh (.0365*75). Multiply that by your kWh cost, and that’s what you pay to use your laptop (before surcharges and taxes).

Once you know what you pay for each electrical device, you’ll be able to begin working on calculating how several kWh you want to have your solar system generate.
