What is Solar Cooling?

The best way to cool your home is to avoid using heat. But if can’t completely avoid the use of heat, and you certainly can’t prevent the heat which comes from the sun. Wind and solar cooling are among your options.

Solar heat can actually help cool your home. When a solar cooling system is set up properly, the hotter the temperature gets, the cooler your home will be. You might wonder how this works …

You can use heat to cool your home by using the forces of nature to pump air and drive the heat away.

Here are some DIY projects that you can consider, in the quest for a cooler home:

1. You can try building a thermal or solar chimney. This is a heated chimney that collects and ejects heat from the interior of the house. Once the chimney collects heat from the sun, it creates a vacuum effect that sucks in cool air, while hot air exits through the top vent. Your chimney can be in the form of a hole in the floor with ducts through the roof. You can cap the chimney with a turbine that will catch air, to help release hot air out of the structure. If you set it up in this fashion, your thermal chimney will be a wind chimney as well. This solution will make your cooling system work during the day, when the sun is up, as well as during the night, when the wind is blowing.

2. You could also use an evaporative cooler. We all know that when water absorbs heat, it evaporates. Thus, when air travels over water, it cools down. This method should be used when there is a low level of humidity. And be sure to use preventive measures against health hazards that can be presented by stagnant water – such as malaria, mildew, and Legionnaire’s Disease. The size of you evaporative cooler would depend on the size of your home. It usually consists of a box containing the fan, and a wet pad. It can be mounted on your roof, or at the side of your house. You can use a windmill to circulate the water that keeps the pad wet. The fan will blow the air through the pad and, and the air will eventually enter into the house via open windows or vents.

These are just some of the ways you can use solar and wind energy to cool your home. There are also kits you can buy – but like most DIY projects you can purchase what you need in a local hardware store. Commercially available kits are likely to cost more than what you would spend if you buy your parts separately, although they might also be faster and easier to set up.

How To Introduce Solar Power For Homes

Considering introducing solar power into your home? Well, if so, you’ll be pleased to hear that I have gathered together some information so you can get a good idea of how much it will cost and exactly what the scale of the job is.

Start by deciding what percentage of your home are you going to be running on solar power. You could use solar power to provide a water-heating system. You could go to the furthest extreme and take your home completely off-grid thus ensuring the whole house is running on solar power. It’s up to you, but you have to find out the average amount of electricity your house uses per month.

To work out the average energy usage of your home, simply dig out your monthly electricity bills going back over the last two years. Get the calculator out. Be aware of the year’s peak times, like Christmas when you would normally go through a lot more power than normal. This way, we can establish your home’s solar power system so it can surely cope with all of your home’s energy demands.

Now, so you can sleep easy at nights, multiply that amount by a minimum of 1.5. If any extra appliances are brought into your house you remain fully covered. So, by the time you’ve done this you will know how much solar power you need. You will also be able to tell how many solar panels you will have to buy and what size they have to be.

In this day and age, you would almost always be best advised to look online when buying solar panels. Go to Ebay and enter the words “solar panel pallet” exactly as is. Sit back and be prepared to be amazed by the incredible bargains you will find there. If you think they seem expensive, please don’t forget that these prices are a one time cost and solar panels tend to last 25 to 30 years.

In every case, always employ a skilled, experienced solar power technician to install your solar power. You will find plenty online or in your telephone directory. Keep going until you have three quotations for the job, but don’t necessarily choose based entirely on the price. Cost is important, but you may feel more confident to get a job well done from an experienced solar power technician when installing solar power for homes.

You will also have to shop around for a good quality inverter. Solar panels give out direct (DC) current when harnessing the sun’s energy. The inverter will convert this DC current into alternating (AC) current from which we can all enjoy running all our electrical toys and gizmos.

Roughly costing $2,000 plus maybe $500 for installation, inverters will last you roughly 10 years. Bare in mind solar panels.

If you want to go off the grid completely, it is essential that you use good quality batteries to store the excess solar power you pull down on sunny days. Use this reserve of power to run your home’s electrical needs at night-time. The deep-cycle batteries will probably cost $50 to $100. I suggest you buy 10 of them. Their longevity is not so good as the inverter. Expect to have to replace them every 3-5 years.

Always ask your local authorities if they will give you any assistance for the cost of installing solar energy. Most local authorities offer tax credits. Ask your local utility company as well. They might have some good incentives or special deals. Do this right and you could save 50% off the total cost or more.

Although it is essential you get a qualified electrician, it’s reassuring to know that installing solar energy doesn’t mean you have to have a lot of electrical work. normally, the older the house, the more additional rewiring will be needed. However, this is not often an extensive job. I repeat though, be sure to use an experienced, qualified electrician.

Always remember that solar power is a long-term investment. When estimating the value of installing solar power, the question is, “What is the payback time?” After knowing that you now have a house that will be enjoying free electricity for many years to come!

The Cost of solar energy to generate electricity

Massive generation of electricity comes from fossil fuels. Now there is a huge demand for electricity but there are the fossil fuel reserves are decreasing every day. The solar power is gaining much attention since it is generated from sunlight,a natural resource that is available in plentiful. Even though Solar heating was used for centuries,solar electricity is now having greater demand. Taiwan has recently opened officially its first fully solar powered stadium. The Solar systems that are designed to replace electrical usage is now catching on in a very big manner.

 

The concept of using solar power for homes has come a long way in a relatively short period of time. The solar technology using solar cells converts the sunlight into electricity. The generated electricity can either be used directly or stored in the batteries and used for various applications like running tube lights, computers, dishwasher, ice maker, fans and TV etc. One of the major doubts that most of the people are what is the cost of solar energy? Is it cheaper or costly? Regardiing this let me share some information.

 

One of the major issues with the cost of solar energy has been that it costs more than electricity that is generated by conventional means. The Energy of sun is free but the technology required to convert it into electricity is expensive. The cost of solar power for one unit is Rs 15 while it costs just Rs 1.From coal it is 19 per unit. The price of solar power varies on the power wattage utilized by the consumer. More amount of amount means larger solar panels which comes at a higher price. The Price of a good home made solar water heater system is $14000. One can reduce their monthly power bills coming from heating hot water to 50%. The cost of a solar energy system to power a computer and few other small items will be around $700 to $1000.

 

The cost of solar power for your home depends on how much energy in kilowatt-hours (kWh) do you use per month. Investing by Dollars per Watt is the best way to choose solar panels. For last one decade,the price of photovoltaic panels have fallen at a steady rate of 3-5 percent per year. However, prices may not seem all that low to you, because in general the technology is getting better, so each panel is making more watts than those of a few years ago.

 

Because of strong demand for large photovoltaic installations around the world, there has been a general shortage of new panels. Search through local newspaper classifieds for PV panels. The Banks & Government provides loan facilities for purchasing solar lighting and heating systems. If you buy the solar panels for your house, then your insurance company also insures them, just like they insure the rest of your household items.

 

 

Now solar enterprises are spreading the awareness on the huge potential demand for solar batteries in the domestic market supported by government and implementing low priced solar technology. Unlike fossil reserves, which give power to the countries as long the resources are available, the sun is a limitless energy provider available to several generations. The Future will soon have vast solar farms generating cheaper electricity for the entire cities without emitting any pollution.

How Much Does Solar Power Cost And Can You Afford It?

The world needs a new source of energy. The current primary energy source is fossil fuel, which is not only expensive, but also hazardous and will eventually run out. With all these disadvantages, people are now becoming more aware of the advantages of using other sources of energy, such as solar power. But how much does solar power cost?

Using the sun’s radiant energy has some distinct advantages. Such as:

- It is free. As long as the sun comes up, you can tap into its energy.
- It has an unlimited supply. Unless you plan to still be here in a few billion years, the sun will always be there.
- It does not produce pollution.
- It will help you save money.

Solar panels today are very efficient. There are several types of panels out in the market. But the question is how much does solar power cost? The answer to that question can be tricky to answer. That’s because various types of panels can be determined by the efficiency and price. The balance between these two factors may give you the answer to the question.

There are two basic types of solar panels – One is crystalline silicon and the other is amorphous silicon. Amorphous silicon is much cheaper to produce, but is less efficient in producing electricity. Crystalline silicon, on the other hand, is more efficient in converting the sun’s energy to electricity but is much more expensive. To be able to find the right panel for you, here are a few of the solar panels that you can buy on the market:

- Sunsei SE-4000 – This solar panel is a crystalline silicon type that has a maximum power output of 65 watts and is priced at around $650.
- Kyocera KS20 – this is another crystalline silicon type that has a maximum power output of 20 watts. Its price is about $300.
- Silicon Solar – This is an amorphous silicon type that has a maximum power output of 40 watts. It is priced at around $250.
- Sanyo HIP-195BA3 – This is a combination of crystalline silicon and amorphous silicon. It costs about $1000.
- Then there is the do-it-yourself model. These can typically be made for less than a hundred bucks. They probably won’t be as efficient as the professional models and will take a few hours of your time to build it, but they can save you a lot on your initial investment.

To learn more about do it yourself solar power, be sure to read our Energy4Green review.

So how much does solar power cost? By looking at all these figures, the cost of these panels would be at $5 per watt, $10 per watt or $15 per watt. But remember that the numbers shown are the maximum output. The output will vary based on the intensity of the sun where you live.

Why Solar Power And Solar Panels Important

We have ways to heat our water, our homes and provide us with electricity. We probably take all of this for granted and if we lost them we would probably panic. We take for granted that these conveniences will be there for us from now on. We expect glitches to happen but we want them to be fixable without going long without all of these. We appreciate the heat in the winter when it snows outside and when the temperatures drop. We need water to live and although it is usually running under the ground we want the convenience of it running through our pipes and into our homes.

Some people use some of the heat generated from the sun in order to heat homes, power electricity and provide water to their families and businesses. When you think about all that you have that runs through a machine it may be possible to reroute that in order to run it all by sunlight. Scientists have only started to make this possible but it is far from being completed. When you consider all the solar energy that reaches the earth’s surface and then radiated back into the atmosphere, you could power electricity, heat and water from now on. This solar energy can be redirected and concentrated using special boxes that attract the light during the day to heat water and homes throughout the night.

Solar energy would not be affected by the supply and demand of fuel for it is free and it doesn’t pollute the atmosphere. It is natural and pure. It would provide us with better health.

In the beginning you may pay a minimal amount to be solar power efficient by purchasing a solar source. You can buy indoor and outdoor lighting, solar power windows and insulated doors in order to make your home more solar efficient. After that initial expense you don’t have the expense of paying a monthly bill to keep your service on. This also promotes others to use solar power to be more efficient.

Solar panels importance

Solar panels can be different shapes and sizes but their main purpose is to convert the light in order to make electricity. Photovoltaic, or PV, is the process of converting the light into electricity. Photovoltaic cells are self generating and consist of a very thing film made of silver. This film is placed on a semiconductor layer that can be found on an iron substrate. The photovoltaic cells are very important in producing enough sunlight and heat in order to successfully produce the energy that is needed in order to heat up water, heat homes and power electricity.

Solar panels can be found in all different shapes and sizes including round, square, and rectangle. You can see them on top of buildings and houses or standing alone in fields. Solar panels are in hand held devices and they are in energy efficient appliances. The sun is a wonderful natural resource and can greatly cater to our way of life. The study of natural resources like the sun is ongoing and the improvement that can be made in the future is anyone’s guess but you can’t go wrong when you use natural resources.

Loans for Buying Solar Power Equipment for the Home

With today’s economic crunch affecting every citizen, we still continue to try and alleviate the situation by finding ways on how to really cut our daily expenses. A very effective way on how to achieve this is to cut costs on our energy consumption. Preferring to use the smaller displacement car over the usual gas guzzling SUV when heading out for some groceries would really save us some precious money in terms of gas payment. Another important way on how to really cut down energy consumption is by installing solar equipment in our home.

There are basically two types of solar installation we can have, the first one transforms the solar energy into electrical current and the other one transforms the energy into heat for rooms and water. Having any of these system will bring significant reduction to your household costs. But the downside to this is that the average rate for a household installation of the second type, would be from $6,000 to $7,000. The first type, the photovoltaic system would set you back around $18,000- $25,000. Sure, they a considerable amount of money on the up front, but come to think of it, it will save you tons of money monthly and it wont be long until you can finally recoup what you have just shelled out. With today’s economic situation, investing on these system would be prove to be a logical investment. However, with the economic meltdown, it would not be a wise idea to pull out that sum of money out of the stock market just to have these systems installed in your house. It’s a good thing that there are a lot of companies out there which offers to have these solar power systems installed in your homes through flexible payment schemes and affordable loans.

By enticing as much home and business alike to use this viable alternative to conventional energy, you not only  get to have thousands of dollars in savings, but you also help save the environment by minimizing the people dependent on conventional energy and minimizing somehow burning of fossil fuel. The potential of having solar energy as our main source of power remains to be undermined primarily because of the high cost of installation. However, with more and more companies that offer realistic payment schemes, it won’t be long until we can finally bask under the sun, and full enjoy the benefits we can derive from it. And the best part about using solar energy, is that it doesn’t emit any harmful emission and noxious gases. And lastly, the energy we can derive from the sun does not deplete, unlike in fossil fuel which, as scientists have predicted, half of the earth’s total supply of fossil fuel has been already consumed.

Simply browse over the internet, I’m pretty sure there’s one company in your area able to give you the suitable financing scheme for solar equipment in your home or business.

Home Solar Panels : The Facts

Users can now install solar panels in their homes and reduce their electric bills while preserving nature at the same time Although this technology gives countless of benefits, people are still hesitant to use this mostly because of the installation fee and its functionality.

 

Factors such as site location, house orientation, obstructions to the sunlight and the weather must be considered in setting up solar panels Even when these considerations aren’t optimal, there are solutions enabling you to utilize solar energy to power your home. The effectiveness of your solar panel depends on the amount of sunlight it receives, needing about six hours of constant sunlight the year round Solar panels work best if they are installed in an angle of orientation facing the sun.

Solar electric power, which use photovoltaic cells in converting solar radiation to electricity, and solar thermal energy, which uses the sun’s energy to heat up water are the two types of solar power

A good solar hot water panel system is able to provide an average household with around a third of its annual hot water supply. At first glance, this may not sound much but it can cut back energy cost by considerable amount With the integration of solar panels in addition to this hot water system, plus the addition of other renewable energy sources such as residential wind turbines, they can all work together in providing a renewable, cheap and clean source of energy for your home.

How home solar panels look on the roofs is another concern for some homeowners Photovoltaic panel designs, thanks to the latest technology, are now smaller and more compact. Today, these panels would look like ordinary roof tiles, only with the functionality of a solar panel; they can keep out the sun and rain, and with the ability to convert solar energy into electricity, helps out in cutting back electricity budget

One advantage of solar powered home systems is that energy can be stored in battery packs and chargers, so energy sources are still available even during fall and winter, when there are shorter periods of sunlight.

While it is possible for a household to run completely off photovoltaic electricity using solar panels, this is unlikely in most cases The costs involving the installation for a whole house with electricity from solar energy would be quite high for the average homeowner. It is preferable to use solar panels together with traditional power supplies It is much more cost-effective and energy-saving than depending on fossil fuels alone. You will still depend on fossil fuels but the solar electricity can still provide substantial amount of power, enough to reduce future energy bills
Installation fees can be expensive, but with the constantly rising utility rates, having a supporting source of energy for your home is a good investment. Not only does it protect you from price hikes and power outages, but you will also be protecting nature by using a clean and unlimited source of energy. Solar energy can lower your fuel costs, particularly when used in conjunction with home wind turbine systems.

Advantages of You Using a Portable Solar Power Source

There are so many wonderful useful benefits that you receive when you make the switch from fossil fuels to solar power, and just a few of the most important will be discussed here, so that you can better understand about solar power and all that it has to offer.

Benefits

Whether you use a portable solar power station or other means of portable solar power source, you will still be getting pretty much the same benefits. One of the most important and talked about benefits offered by a portable solar power source is that with it you will be doing your part to prevent further damage to the environment.

This is an issue which has never been of more importance than it is now, as we are facing global warming and other horrific environmental issues.

Another benefit of using a portable solar power source is that you will be saving yourself a great deal of money. This is because rather than needing to pay an electrical or gas bill every month, when you are relying on a portable solar power source all you need is to spend the money initially to purchase the system or kit, and after that you are relying on the power by the sun so you will have few to no costs.

Solar power is a renewable energy and so you never have to worry about it running out. No longer will you have to feel bad if you leave the lights on or keep the television running while you go out for a couple hours.

So if solar power offers all these benefits, why hasn’t everyone jumped on the bandwagon? There are a couple of reasons actually, but the main reason that some people are iffy about making the change is because they are simply confused. A lot of people do not understand completely about solar power and think that it would be too much money or too much hassle for them to make this change.

In reality, by switching to a portable solar power source you will not only be receiving all these benefits and more, but as well you will see just how simple it really is. There are no huge differences or changes that you are going to have to deal with, and the process itself can take as little as a day. Just make sure that you have your portable solar power system installed professionally, to ensure that it gets done right the first time around.

Home Solar Power Systems Are Gaining In Popularity

Hiring a contractor to do the installation for you can be quite expensive. Therefore, it is important that you get quotes from several contractors before making a choice. For installing Home Solar Power Systems, a contractor’s price may vary from fifty dollars per hour to three times that charge. A reputable contractor should provide you with an all-inclusive price quote for the installation of your Home Solar Power Systems. On the other hand, some entrepreneurs try to offer an “estimated” price. Unless a contractor has a long history of satisfied customers you can contact, it is a bad idea to go with one who will not give you a firm price. Otherwise, you may be charged thousands of dollars for unnecessary expenditures on tools and services.

Advantages of Home Solar Power Systems are that there are no moving parts to break and very little maintenance required. Whatever the size and purpose of such systems, there are two basic types of home solar energy systems:

1. Active systems are good when there are periods without sunlight. Such a system is connected to a power grid for additional supplies of electricity.

2. Passive systems are entirely dependent on sunlight and are a fine choice where clouds and rain are not an everyday occurrence.

Home Solar Power Systems

With a renewed interest in non-polluting energy production, there has been more research into and better acceptance of Home Solar Power Systems than there has been in the past 40 years since their debut. The earliest systems required a high investment in the structure and were only considered effective for certain regions of the country. However, as global warming, air pollution and the rising cost of electricity are becoming major environmental issues, interest is now high for solar energy systems. This is truth for individual residential systems or large plants which supply energy to entire communities.

Home Solar Energy Systems Have a simple theory that requires complex structures:

The theory of how Home Solar Power Systems work is fairly simple. Photovoltaic cells, designed to convert sunlight into electricity, are pointed to the sun and connected to a device that operates on 12 volt direct current. They can also be connected to storage batteries to save any power not used by the device. Then, when the sun goes down, the unit can continue to operate from the power stored in the battery/batteries. Some initial challenges had to be overcome, such as not having any devices in a house operating on 12 volt direct current.

Home Solar Power Systems

The amount of energy produced by Home Solar Power Systems can be increased by adding cells. Likewise, by adding more batteries, more power can be stored overnight. Adding a converter to a home solar energy system permits the use of 110 volts AC, which powers most home appliances. Moreover, having a regulator prevents the batteries from overcharging and helps guide the power to where it is needed.

Technological advances have produced photovoltaic cells that are thinner and more efficient, which makes the overall reimbursement time for the installation much shorter and the installation of Home Solar Power Systems more attractive for residential and commercial use.
