Understand Solar Panels and How They Work

Posted on 24th June 2011 in environment

Solar power is a good green source of energy and a serious option to consider for your energy needs. Other options such as wind turbines and hydroelectric generator can be used in but for most homes and smaller business solar is one of the most achievable options.

Solar panels and solar power generates power from the sun by converting sunlight to electricity with no moving parts, zero emissions, and no or little maintenance. A solar panel is made up of a series of individual silicon cells that generate electricity from sunlight. As the light hits the surface of the solar panel the light particles produce an electrical current on the surface of small silicon wafers. One single solar cell produces around half a volt of energy.

Smaller solar panels can produce up to 12 volts of energy. These smaller panels contain an average of 36 solar cells. Large solar panels will produce up to 24 volts of energy. These will contain around 72 solar cells.

Solar panels can be wired together to create a bank of panels and increase the amount of energy you can harness. This gives the advantage of using a higher voltage output so the solar panels can use smaller wire to transfer the electric power from the solar panel to the output, charging batteries for example.

Solar panels come in different types. One is a Monocrystalline solar panels. These are most efficient but the most expensive solar panels made. The solar cells use very pure type of silicon and use a complicated growth process for the silicon crystals.

The middle ground for solar panels is possibly Polycrystalline. This type of panel is sometimes called Multi-crystalline solar panels as they consist of a range of Polycrystalline cells. This form of solar panel is less expensive and less efficient than the type using Monocrystalline cells. This is down to the fact that the cells are not grown in a large block of many crystals.

The Amorphous solar panel is not made from crystals like other types of panel. These are metal or glass coated with a layer or silicon to create the solar panel. Amorphous solar panels are in the bracket of the cheaper type of panel, as they are less expensive than other types. This type of solar panel is less energy efficiency so more are needed to generate the same amount of energy as more expensive alternatives.

Solar panels are a real option and a potentially good investment to help save money and energy. After the installation and set up costs that can be expensive and off putting, the payback will work for itself. For homes and small business solar is a real solution to meet the demands of trying to find lower costs energy and reduce your energy bills.

Solar Panel Maintenance Ideas

Posted on 14th June 2011 in solar

Solar panels are designed to capture the sun’s light and convert it into electricity. The panels feature an array of solar cells and are linked up to other compartments. They’re installed in groups of three or four in places where they can capture sunlight, often on the roof of homes and other buildings. To ensure your panels are able to function properly and provide adequate power, make sure that they are properly maintained.

Thankfully, these devices require only the minimum amount of upkeep. The heating pump is the really only component that features any moving parts and the only breakable part is the glass covering of the panels. Even though maintenance will be light, it’s wise to stay on top of it.

Inspecting your solar panels periodically is the first step. Dirt and other pieces of debris will have to be removed to prevent damage. Look at the owner’s manual supplied by the manufacturer to see how often you should check them. If there’s a reason to check them more frequently – a nearby tree for example – take that into consideration. Panels that are installed in exceptionally dusty environments will need to be inspected more often. If it helps, create a schedule or mark your calendar to keep track of the device’s maintenance.

In order to remove an accumulation of grime and dirt particles from the panels, scrub gently from time to time. Use soap and warm water to loosen the dirt and a clean cloth to wipe it away. Bird droppings are commonly found on solar panels, since they’re usually located on roofs. You’ll need to completely remove them to maximize the amount of sunlight that gets through to the solar panels. To avoid leaving streaks and water spots behind, cool the panels down with room temperature water before applying the soap.

Don’t remove the solar panels to clean them. That’s more work than it’s worth. You will have to use a ladder and some safety gear to climb up to them. A large amount of ladder and roof related accidents occur each year so it is very important that you take every safety precaution as you inspect and clean the panels.

In order to function properly solar panels must be kept completely clean. A dirty panel could mean that you get little or no use out of it. Cleaning them is not just cosmetic. It’s necessary if you want your solar energy system to perform its job.

There are other options besides climbing to the roof of your home. There is a tool available that allows a home owner to effectively clean their solar devices from the comfort and safety of the ground. Much like the devices used at a self service car wash, a long metal pole sprays a powerful steady stream of water. Most of the devices are intended to hook up to the water spigot in your yard.

Professional solar panel cleaners are also a possibility. These companies can send experts out to your home to inspect and clean rooftop solar panels. They have the proper tools and knowledge to keep them clean and working efficiently. Look in the phone book or online for local businesses that offer this service. Or ask the contractor that installed your system. Make sure you do your research and shop around for the company that offers the best overall deal.

Solar Energy – The Main Advantages

Posted on 1st May 2011 in solar power

Renewable energy sources like solar energy and wind energy offer people many advantages. Solar energy, for example, is the best source of energy humans can utilize to its fullest potential. Solar energy is the energy coming from the sun and is virtually limitless and offers many solar energy advantages. This means that humankind can use this energy for whatever they intend to and for how long they wanted to.

There are many solar energy advantages. First on the list of solar energy advantages is that it helps in saving Mother Earth. The next advantage is what really lures people into using it – cost cutting. And of course, one of the solar energy advantages is the government incentive programs for people who are going green.solar panels

The price of today’s electricity from commercial power companies is steadily rising and that is why using solar energy is such a tempting option. There will be no recurring monthly expenses when you use solar energy. What you would pay is for an up-front payment for installing a solar system that will provide you electricity from solar energy. Once done, there will be no need to worry about additional expenses since the solar panels that will be installed are long-lasting and only requires little maintenance. Moreover, there are no longer power interruptions since solar energy can provide continuous electricity.

One major solar energy advantage is its cost cutting benefit. You see, the only time that you are going to spend a considerable amount of money when using solar energy is during the installation of a solar power system. After that, there will be no more additional costs. The maintenance for the system is not that much of a burden. Solar power systems are long-lasting and stay very efficient. Moreover, solar energy makes sure that there would be no power interruption since the energy captured can be stored in a battery for later use.

Government incentive programs are also there to aid future green individuals. These programs include tax exemptions or reductions, financial aid, rebates, and additional renewable energy source laws. All of which are aimed to help those individuals in switching to a greener electricity source. If you wanted to earn money while saving Mother Earth, you can also do that. Simply sell back the excess electricity produced by your solar power system to the national grid and you can earn some money at the end of every year or a certain time period. This is made possible because the government allows it.

There are many advantages that solar energy offers to people. All of them can be beneficial not only for the person using solar energy but to all of humanity. When using solar energy, you can save money while saving the Earth.

Ways to Reduce Energy Usage

Posted on 3rd April 2011 in environment

The most important thing to do is have a family discussion on energy savings. Maybe offer some type of reward for those who actually save on energy costs in the house. Make sure to give your family easy to follow tips like turning lights off when not in the room. Another big one that many people forget is to simply unplug appliances when not in use. Tat alone can have a dramatic effect on energy costs. Just remember that one drop of water can make an ocean!

We may prefer to switch off the television set or turn off the fan, but not the light.We need light at the time of night but see that the usage is required in all the rooms or not.Taking care of such these small precautions will surely leads us to savings in the long run by reducing the bills of the power demon.

One should plan to invest smartly on power. Replace all the incandescent bulbs present in the house with compact fluorescent light or those CFL bulbs. These bulbs consume less electricity as they consume less power.

You may also want to check out the energy saver products that can be found online or in your local store. These little gadgets “watch” the energy consumption in your household and give you a better handle on how to control that usage.

Many homeowners seem to believe that their electric bills are getting higher due to all the electric gizmos we now have in our homes. However the real truth is it’s not the amount of electric products but how we use them in our daily lives.

Take a step forward to avoid using those typical items regularly that consumes lot of power -

* The washing machine should be used only when there is a bucket full of clothes.

* The faucet should not be kept on for maximum amount of time.

* I know it gets hot but only keep your air conditioner at a low temperature.

* Take note to switch off the computer monitor when not in use. It consumes maximum power and it just takes a second to switch it again.

Lastly we suggest that for reducing the electricity bill by taking benefit of reading the energy saving guide like Earth4Energy that has some of the best solutions to generate energy at home and providing free electricity to some of your home appliances. In this way we can save power that is facing a huge shortage because of the large demand in the global countries. Try to reduce the requirement of those electrical wires and sockets for home and use the renewable energy extracted from natural resources like wind, sun, tides at a lesser price but having a long term returns.

Harnessing The Power Of The Sun To Make Solar Electricity

Posted on 1st March 2011 in energy

Free energy … What a dream, eh? One of the biggest household burdens is the cost of energy. The cost of energy is frequently 40% of total household bills. So, free energy would assist every family that is not rich a great deal. However, free energy is a pipe dream, is it not? There is alternative energy, that is non fossil fuel based energy, like nuclear energy, but that is not low-cost either.

Other alternative sources of energy include wind-driven turbines and solar power. In this piece, I want to talk about harnessing the power of the sun to create solar electricity. Creating solar power is nothing new and most people are acquainted with the general theory of how the scheme works. In deed, most of us have owned a solar powered pocket calculator or solar powered clock at one time or another.

Solar electricity is just as good and just as powerful as traditionally generated electricity and they can be utilized for exactly the same purposes. However, solar energy has one huge benefit, it is not ‘dirty’.

Electricity produced from the sun’s energy has not been made creating any greenhouse gases whatsoever. Additionally, because there are no moving parts in a solar panel, there is no wear and tear and so less maintenance.

Solar panel systems are more adaptable too. For instance, if you have a small house with couple of appliances, you still need the same method of delivering grid electricity as a huge house and you still have to have a metering system and a means of paying for the electricity consumed.

However, if you take the same small house as an example, you might find that ten solar panels will power it. Therefore, for a one-off payment, you are free of electricity pylons and their cables, the meter box and the monthly bills. A huge house would just have to fit more panels, say a hundred, to achieve the same freedom.

This freedom from the instruments of supplying electricity is a very real benefit if you live in a far-flung place, where you are expected to pay for the electricity pylons and their cables all on your own. The down side of using solar power is the cost of setting it up. A professionally installed solar energy system can cost about $30,000.

If you save $200 per month on electricity, then you will recoup your expenditure in about 300 months, which is 12.5 years. However, if you could get the system fitted more economically, you would recoup your costs more rapidly.

This is possible, by assembling the solar panels yourself and installing them yourself. No matter what sort of a ham-fisted person you think you are, you can put together and fit the average solar panel kit. In fact, most teenagers can do the job. If you decide to buy solar panel kits to assemble yourself, you can save about half of the above costs, but if you were to make the panels from parts that are easily obtainable in DIY shops, you could be harnessing the power of the sun to make solar energy for up to 75% of the cost of a professional installation.
