How To Use Rv Solar Panels

June 20th, 2010

RV solar panels are a newer and more sensible approach to RV energy supply. They can save the battery and campsite electrical price and give the final word mobility. Most RVers do not think about using solar panels as they suppose that they are complex and can’t generate sufficient power; that is wrong. These solar panels are actually easy to install they usually can fully provide the RV’s required electricity needs. The power consumption in RV’s will not be usually that high.

The approach the photo voltaic panels create power is called the “Photovoltaic Process” and it’s a simple one. When this occurs, gentle is transformed to electrical energy or the move of electrons. The solar panels are made from a semiconductor named silicone (SI). When mild is solid on the solar cells, the electrons within the semiconductors get excited and cause the free electrons to move across the entire circuit. This then leads to the direct present of DC. The total electricity will depend on how huge the panels are and their wattage.

Some elements are required to setup the RV photo voltaic panels. First, the photo voltaic panel, dependant on the RV’s present requirement, then a charge controller which supplies the appropriate amount of electricity. The sun is probably not available always during the day and the photo voltaic panels won’t generate electrical energy at night. This implies that there will clearly be a necessity for one thing to retailer the current. That is why storage batteries are needed. RV solar panels will generate the electricity and ship it to the cost controller, which then convert the quantity of voltage equipped to the quantity that the batteries can store. Without the controllers, excess quantity of current may be passed to the batteries and may damage them.

Most of the electronic devices within the RV use AC, which solar panels don’t supply. To clear up this problem, a DC to AC inverter is needed. It converts the DC voltage to AC. All in all, there are four essential things to make use of in photo voltaic panel of RV’s. They are the photo voltaic panel itself, charge controller, storage battery, and an inverter.

To acquire more energy and voltage, multiple solar panels could be connected. The ensuing voltage will depend on the approach the solar panels are connected to at least one another. For example, if two 12volts of solar panels were connected in series, then the setting will produce 24volts and 5amps. This is finished while connecting them parallel will lead to 12V and 10Amps.

When camping in remote places, the place electricity is not available, RV photo voltaic panels are the perfect solution. They are reliable and will save you the price of changing batteries regularly.

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.

What Is Solar Power – Your Questions Answered

November 20th, 2009

Basically, solar power is energy that is actually harnessed from the sun. Although the sun is millions of miles away from earth, if we had the ability to harness all the energy coming from the sun, there is more than enough power there to provide all the energy we need for the entire earth. In fact, there is enough energy to provide plenty of energy for 10,000 earths. While you can use solar power for a variety of appliances and other items, you have to realize that this is different than using this power to produce heat.

There are two different principles that are used with solar power. If you want to produce hot air or hot fluids, then solar thermal principles are used. However, if you want to product electricity, photovoltaic principles are used instead. If you want to produce solar power, there are four components that are needed, including a battery, a charge controller, a solar panel, and an inverter.

It is the solar panels that actually get the radiation from the sun and use it to charge up the battery. Then, the charge regulator actually makes sure that the battery charges as it should. Of course, probably the most important pieces of equipment are going to be the solar panels and usually they output energy in watts. These panels can be wired in a variety of ways, although usually parallel or series wiring is done to either increase the amperage or the voltage.

So, are there benefits to using solar power? Yes! There are a variety of amazing benefits to using solar power. In fact, many people all over the world are already using this type of energy to supply their electricity. Some of the benefits are as follows:

- Creation of new hi-tech jobs

The Components Of Your Solar Power Solution

October 30th, 2009

When beginning a solar energy DIY home conversions project, one question many people have before they start is: What will I need to complete the conversion?

Of course before you start with anything, you should get a good DIY solar guide, and you’ll be walked step by step through the process of setting up your solar energy solution. Aside from that though, let’s cover the basics of what you’ll need to go solar!

There are 7 main components you’ll need when wiring up a solar energy solution for your home. It should be noted here that we’re talking about converting a home, and not just creating portable solar energy solution (in which case you’ll only need 4 components).

Before you install your home energy solution, you’ll need the following components. These are listed in the order they will be wired into your solar energy system.

1. Solar Panels – In most DIY applications these will be built by you. You order discount photovoltaic cells, and assemble those into 50W, 75W, or 100W Panels.

2. Array DC Disconnect – This simple device is basically just a switch. It allows you to cut the DC power from your solar panels should system maintenance be required. If you shop around you’ll likely pay less than $25 for this component.

3. Charge Controller – Most home systems will be built with a battery backup. The charge controller ensures that a consistent amount of power is sent to the batteries, and that the batteries don’t discharge at night. Again, if you shop around for this component, it won’t be a large expense.

4. Deep Cycle Batteries – To store the power from your solar panels, you will need deep cycle batteries. If you find reconditioned batteries, these can be obtained for fairly cheap. Better yet, you can get old batteries for free and recondition them yourself.

5. System Meter – This component is actually optional, but it is suggested so that you have a clear way to see how much power is being fed into your home from the solar panels.

6. Converter – Since your solar panels produce DC power, and your home runs on AC power, the converter makes the solar energy usable by your home. A 1500W converter likely won’t cost you more than $50.

7. Backup Power – Most systems will also include some sort of backup power. In an off grid application this would generally be a generator. In a city or town, the power grid itself provides the backup.

From there the system gets wired into your home breaker box. At this stage, unless you are qualified, you might consider getting a qualified electrician to install the system. At any rate, you now have an idea of what will be needed to get your home running on solar energy.

If you haven’t done so yet, you should also consider downloading a copy of one of the best solar home solutions guide to teach solar panel DIY. Doing so will ensure you have all of the information you need to get the conversion finished right – the first time!

P.S. Don’t forget to follow the latest trends in alternative energy solutions and stay up-to-date.

The Advantages And Disadvantages Of Using Renewable Energy Sources

September 22nd, 2009

Wouldn’t it be great if we can produce our own green energy source? If we can do that, we don’t have to pay electrical bills or gasoline anymore for our cars. While we can buy some of the equipment, the rest will have to be done on our own.

You can read more about this topic at the Renewable Energy Blog

Take solar or wind energy for example. We already know how to harness and make it. If you want to make one, do some research online and then set up the system yourself.

To have solar energy, you will need to buy an inverter, battery, charge controller, solar panels, some wires and support structure. The only difference with wind energy is that you need a fan. Once you have everything you need, you can put it all together.

If you are not skillful, you will be happy to know that some companies sell the entire system. By buying it from them and having it installed by their experts, you are sure that there won’t be any problems the moment you switch it on.

There is one more thing you need before you can use one or the two green energy sources. Before you buy the materials or the system, make sure you have a flat area that is about a hundred square feet or so because it occupies a lot of space.

For those who don’t have the space or the budget to use these two energy sources, another option is to create your own biofuels.

Biofuels are used in many countries and they get it from harvesting corn, sugar and other crops. Luckily, you don’t need a farm to produce it because you can also make your own using some recycled waste.

A good example of this is vegetable oil which we use for cooking. To turn this into a biofuel, we first filter it by warming up the liquid and then filtering this with a coffee filter. The next step is to remove the water also by boiling it again at 100 degrees for a short period of time.

We need to know the amount of lye present in the vegetable oil and we do this by a process known as titration. When we are done with that, we now mix sodium hydroxide to produce sodium methoxide.

The process of converting used vegetable oil before it becomes a biofuel takes quite awhile and it must be heated the entire time. This is done so the fuel we produce is pure and only when this is achieved that we give it time to cool.

Just how much biofuel we make after all the work varies but you will have an idea of how much you have produced since this is the one you see floating at the top. If there is still some glycerin present, filter it again. From there, you already have your own backyard biofuel which you can use and even sell to those who are just as concerned with the environment as you are.

By making our own green energy sources, we make ourselves less dependent on gasoline in its various forms to power our heater, home or car. Why don’t a lot of people do it? Well simply because they don’t have the time to make it and would rather rely on someone else to do it for them.
