3 Solar Energy Facts

The government can help foot the bill. Solar power is a big thing in many developed nations like Japan and Spain. In places like those, the government helps consumers and private companies to switch to solar energy, if it doesn’t already make the switch itself.

North America is no exception. In Ontario, Canada, for example, the local government enters into power production contracts with homeowners to help them recoup the cost of the solar panels faster. Meanwhile, in the United States, there are programs such as the Residential Energy Conservation Subsidy Exclusion that gives tax rebates or utility bill credits to homeowners with energy efficient facilities like solar panels.

It’s getting cheaper. When talking about solar energy, fact is that it’s getting cheaper and cheaper – by about 5% every year, in fact. Just compare how available the technology is today and how only NASA was able to get it a decade ago, and you’ll see that the trend has long been in favor of the mass market. You really can save money on electricity by using solar power.

Even better is the fact that it’s also becoming more available. Contractors installing solar power systems are now a common sight, and the rates are typically competitive. Do it yourself solar panel installations aren’t far away; even today, some home improvement retailers in states like California offer solar panel kits that you can assemble yourself.

It’s much, much cleaner than power from fossil fuels. The average American family requires a solar power system capable of generating around 3 kilowatts of juice. Getting that same amount of energy from traditional fossil fuel sources would require burning more than 500 pounds of coal, to produce almost a thousand pounds of carbon dioxide. In contrast, solar panels require minimal maintenance and have absolutely no emissions.

Cost-wise, things still aren’t cheap as you might like because the technology still isn’t very mature. Better developed solar technology, however, should be on the market within the decade. In the meantime, many governments can assist in funding solar installations and help you save money on electricity costs. You can also build your own solar panels and save money on start up costs.

Planning Panels

As with any solar power setup, it’s the solar panels – the photovoltaic cells – themselves that are the most crucial part. Without them, you’d be limited to a very narrow range of passive uses for solar energy, and you waste all those sun-bathed hours in the day that could have meant watts for your appliances.

One of the biggest considerations when planning a purchase of solar panels is the space. Any solar panel installation will take up a sizable amount of space that’s proportional to the generation capacity of the system. It need not be actual ground space, however; many homes with solar power setups in Europe have their solar panels installed on roofs and on the sides of houses.

Cost is the other major issue that consumers have to deal with for solar panels; they’re not very cheap. If you were to consult with your local energy agency, however, you’re likely to find that your government offers solar power incentives and subsidies.

Planning the Rest of the House

Besides just the panels, you can do other things to make your solar power house even better. The modern solar house is a two-part plan: the power generation – the solar panels themselves, in short – and the power usage reduction. That is, aside from producing energy through renewable means, you also have to lessen the amount your home needs.

You could, for example, get tinted windows that block out heat, reducing your home’s need for cooling. Homeowners in colder climates may want to get specially constructed roofs with salts that improve heat capture, lessening the energy you spend on heating. Larger windows facing the right directions reduce the amount of electricity you’ll have to expend on light overall. They’re small factors, yes, but they all add up over time.

A solar power installation with just the solar panels will save you money, but you can take things one step further and design your home entirely around solar power. That way, you save even more money on energy – and become a bigger help to the environment to boot. So your solar power house today! Check around this site for more information.

Who Buys Solar?

Solar power isn’t as new to the block as you might think. It’s been in use for decades now by specialized groups like NASA, which has been sending solar panels to space for much of the life of its space program. What’s recent is the jump from high-budget fields to the mainstream consumer market, thanks largely to advances in the technology made in the last few years.

But the concept of powering homes and cities with the sun and reduce energy costs isn’t a new idea, and neither is it a limited one. As early as the 1970’s, energy agencies around the world – particularly ones in then already developed nations – were already exploring solar power. The Solar Energy Generating Systems project in the Mojave Desert, for example, began operating in 1984 and is the largest facility of its kind on the planet.

Nowadays, everyone can purchase solar generated power in countries like the US, Japan and Germany. But it’s not just homeowners who buy solar energy; the governments take advantage of the lower generation costs, like in the Nellis Air Force Base in Nevada. Nellis gets its power for less than 25% of the grid cost.

Cost vs. Benefit

The next question on your mind is probably about the cost of the technology compared to the energy cost reduction it’ll give you. After all, it only makes sense to get a solar power system if it’ll provide a big significant reduction in power expenses.

It’s a question with a multifaceted answer, but the long and short of it is that the system could pay for itself with savings within about a decade. Going solar does make a huge difference in terms of how much you pay for power. Nellis Air Force Base, for example, pays just 2.2 cents per kilowatt hour with solar, as opposed to 9 cents per kilowatt hour when they get power from the grid.

On the cost side of the equation, it’s true that solar power systems are still a considerable investment today. However, the trend is one of declining prices and increasingly available technology. With prices on the downturn and government subsidies within reach, it makes more and more sense for you to reduce energy costs and buy solar energy technology – soon, if not now.

The Shortcomings of Solar Power

It’s a fact that solar energy systems are far from perfect. After all, the technology involved could still use much development. From this comes many of the problems that could make you think twice about adopting solar power technology in your own home.

First and foremost, the technology is expensive. Solar energy costs by an American family consuming 3 kilowatts would cost up to $12,000 on the average, before rebates. And while DIY kits are now available from some home improvement stores, professional setup is still recommended. The technology is inefficient, converting just around 20%, which means you’re likely not getting a lot of energy bang for your buck.

It also tends to take up a lot of space. Because solar panels aren’t yet very efficient in terms of throughput, the number of solar panels necessary for powering the modern home can take a lot of real estate – not something that everyone today has.

Solar’s Saving Graces

On the other side of the discussion on the pros and cons of solar energy, the technology has a lot of things going for it as well. Of all the alternative energy technologies today, it’s the option that’s most within the reach of every homeowner. Whether you’ve got a small apartment or a sprawling mansion, you can go solar one way or another.

There are also several ways around solar energy costs. Many governments like the one in Ontario and the US federal government offer incentives like subsidies and tax rebates for citizens who are switching to solar power. Add it to the savings you get from reducing your electric bill with solar power, and any setup should pay for itself in a span of several years. Even better, the technology gets cheaper as it gets improved by the year.

Because of the technological limitations of solar energy, costs on paper still aren’t as low as many would like. In practice, however, those costs aren’t as great as you might think. I hope this article has educated you on the pros and cons of solar energy, look around this site to learn more.

What’s Up with Solar Energy?

Solar energy uses arrays of photovoltaic modules to convert the energy from the light of the sun into electricity. This is the same juice that gets stored in batteries or directed into homes for use with any kind of electrical appliance.

First and foremost among the solar energy benefits is the environmental one. A huge part of the energy that you consume today likely came from traditional means of generation like burning fossil fuels. There’s no doubt that solar energy – requiring no fuel and with no byproduct – is the more sustainable and environmentally friendly way to go.

In actual consumer use, solar energy is a practical technology. Countries like Finland and Spain already have solar energy facilities. U.S. homeowners report that at least 20% of their home electricity can be generated via soar energy. Engineers all over the world say that homes fully powered by the sun can be had in the next decade. If you’re looking to find ways to save electricity costs, then solar energy might be just the solution you need.

The Cost Question

And then there’s that all-important issue: how much will it cost you to go solar? If you were to look at just the price tag, then the system to get solar power in your home is far from cheap. But when you put that side-by-side with what you stand to gain, it’s going to be one of the best investments you could make.

Solar power can work alongside traditional power sources. That is, a solar power system at home will serve to reduce your usage of traditional power. Analysts estimate that the average American home buying today’s typical solar setup can recoup the investment in three years with all the savings on electricity. Once it’s set up, a solar power system will continuously produce power without needing fuel or much maintenance, minimizing cost.

The technology to fully power your home with solar power isn’t yet available right now. It can’t be denied, though, that getting as little as 10% to 15% of your power from the sun is one of many great ways to save electricity and cut down on monthly bills. I hope this article have educated you on the solar energy benefits.

A Short Solar Energy Guide

If you’ve ever seen a calculator that doesn’t need a battery to run – the ones with a black strip near the top front – then you’ve seen a solar cell. Photovoltaic or solar cells are specially designed modules of treated silicon that can generate an electric current when hit by light. In a nutshell, electrons in the cell’s silicon lattice can be struck loose by the energy of the sun, and their movement creates a current in the cell.

With enough cells in place, this generated energy can add up to a significant amount – enough to power a home or building in some cases. Large enough arrays of solar cells can create enough to replace traditional electricity in some cases, meaning lower power bills. The savings is one of the biggest solar energy advantages that make it so attractive.

Solar cells aren’t all that new; they’ve actually been in use for many years now. It’s just that, up to about a few years ago, they were limited to the aerospace industry because it was only folks like NASA that could afford them. Nowadays, though, they’ve figured out ways to produce the cells themselves for less, meaning more solar energy for everyone.

But What If…

It’s understandable if you were to have doubts about solar energy at first. After all, it’s a technology that has only hit the mass market in the past few years. As far as consumers are concerned, it’s still fairly new – and relatively costly technology.

Cost-wise, for example, it’s still not as cheap as people would like it to be. Installation of solar cells (and the solar cells themselves) tend to require a fairly big amount of cash out of your own pocket. Once you factor in the savings, though, it’s a whole other story.

How does solar energy work on cloudy days? It’s an apprehension that many have, and is easily remedied. Almost all solar energy home setups can direct the generated electricity to a battery that stores the power. This stored energy from the sun can then be used at a later time, meaning you can use solar energy even on a dark night in the dead of winter.

If it’s all about what you stand to gain from solar energy, advantages of the technology come in spades. Besides just the money you stand to save, there’s also the planet and the environment that you’re helping to save in the process.

There are mainly various interconnected sophisticated components that are fragile by nature and a little bit of lacklustre behavior could takes it toll over the client who is ready to purchase the unit sooner or later. It?s the duty of a hired contractor to specify every sophisticated component of the solar product to the owner with descriptive analyses as to what could happen with the stipulated guarantee of product working for years and the cost of maintenance equires for timely over-hauling of the defined solar unit. With the helpof a contractor the component can be replaced easily as what it might take more time by the cutomer itself. The working procedures of the contractor could be learned broadly according to such terms mentioned: There are different varities and sections of solar unit system such as: A complete ?Stand alone solar system? is economically excellent. The system is used primarily for RV systems; cabins; backup; lighting and for portable power systems. The Photovoltic array size (solar panel numbers) and battery will wholeheartedly depend upon individual power requirements. The solar panels charges up the battery during daylight hours and the battery thereby supplies power to the inverter for improved productivity of the unit. A contractor could recommend to have 2 inverters to supply for AC house current which might becoe necessary to power up large loads used upon for air-conditioners. The two could be demanded as one can wok while other has gone for servicing or repairing work. Certain clients hire contractors because they possess more knowledge and information about the fickle climatic conditions because a particular client might never know prolonged adverse affects of the fickel climatic conditions.

A contractor could also recommend for extra battery storage if in case the system doesn?t work in the first instance. The other basic but important components to be installed in a solar panel unit might consists of charging controllers; cells; arrays; inverters; wirings; etc. A solar panel unit contractor should be an expert to know upon the type of enewable energy source a client demands with years of practising up of installations of such units commercially. A contractor can also be asked about another specific manufacturing enterprise for such products or othe industrialized labors who are the experts working as a team for the contractor. The warranty and service policies are offered by competing bids.

Numerous of us are fascinated by the technology that is solar power – but hardly any of us realize exactly how it has the ability to hold all of the energy that the solar panels accumulate. All of the energy is from the sun – which is why you are not able to gather it during the evening hours when the sun is covered from us.

Because of this special devices had to be made that would be able to store it for numerous hours and with little troubles. There are thermal mass devices that can hold the electricity in the form of heat for ordinary temperatures or for particular seasons.

These systems are most commonly developed with things that have the ability to resist high heat. This includes earth, stone, and water. Some of the more special and well developed systems have the power to lower peak demand, lower the heating and cooling demands, and shift the time it is supposed to be utilised during the off peak hours.

The phase change materials are also utilised for thermal storage and are some of the most low-cost kinds. They are more general for residential homes where they are easier to get a hold of and to put in. These materials include Glauber?s salt and paraffin wax. The first Glauber?s salt solar power heating system was employed in 1948 in a house in Massachusetts.

Molten salts are utilized to hold solar energy at high temperatures. This is essential for storage medium and are more valuable because they are not as expensive and able to stand firm against some of the most severe heat temperatures. There are also off-grid PV systems that utilize rechargeable batteries to contain extra amounts of electricity.

The utility companies announce such increase in prices in their bills, but one has to glance at these bills to know about the impending increase in costs. Unlike these people, there are another group of people who have value and respect for their hard earned money. They know that the power costs are getting out of hand and they search for alternatives like sourcing electricity through solar cells. Nature has gifted us with sunshine and it does not cost any money to access and use the same. The solar power cells convert the light energy emitted by the sun and turn it into electric power. The power can be directly fed into their electric gadgets or it can be stored in heavy-duty cells (like the ones used in automobiles) and use it as and when required.

Ask any person who has installed such solar cells, especially those who have assembled the same via kits available on the net and in stores that specialize in electric equipment, and they will tell you of the substantial savings they are benefiting. Those who are interested in installing a solar power rig in their home first have to calculate how much power they require from such cells. Once these formalities are over with, they can purchase a kit that will provide them with the requisite power. Installing such a kid is child’s play and a basic knowledge of soldering is more than enough. The kits generally contain of individual solar cell modules, an exhaustive and illustrated setup manual and an aluminum panel to hold the completed solar cell array.

These cells are connected to each other in series and the final output point goes directly into the equipment that needs power or to the battery. These kits are so cheap that they pay off for themselves within a few months post installation. The current generation photovoltaic cells convert about 30% of sunlight that falls on them to electrical energy, but scientists are working to make more efficient photovoltaic cells that will provide more power per exposed meter of solar cells. The prime advantage of using solar cells for a solar energy house is that they hardly require any maintenance. Just dusting the panels once every few days to ensure that sunlight falls on them properly is more than enough.

Steps to building or remodelling your Home

Building your own home can have multiple choices regarding home heating source. Solar heating works much cheaper than electricity. In case your choice is solar heating then your home needs to be east facing i.e. in the direction of the rising sun. Thus your home gets the maximum sunshine during the hot period of the day. Fixing Solar Powered Glass Windows also helps to lock the warmth of sun that comes through in the home during the day without letting it escape thus keeping your home warm even after sunset.

Only condition is that the door should be kept closed in order to lock the heat and install insulated curtaining on the windows at night so that warmth remains in the room through out the night. Also ensure that there are not many windows on West side of the house because setting sun may cause the home to cool down quickly.

In case you wish to use the sun as a natural heating source then it is extremely simple to remodel your house. Even though your home is not facing the rising sun, it is quite easy to shut in the sunlight that comes in by building a sun room on the east side of your home to trap the morning sun light thus heating up the room naturally and then with the help of ceiling fans circulate the air into the other parts of the house.

During the day this will not only keep your warm but reduce the mount of time used on other source of heat. While remodeling the home installing solar power windows specially designed to attract the sunlight, will allow trapping it in without letting it to escape. Thus heating your home naturally.

Using solar energy to heat up your home naturally is not only the best way to reduce your energy bill but is environment friendly to because it gives off absolutely zero emissions. A backup heating arrangement can be installed incase the sunlight is not sufficient to heat effectively due to clouds. Thus reducing your electricity bill considerably.
