Solar power is the energy of the future. Learn how to get cheapest solar panels for home energy. A few of the several advantages of solar energy are first and foremost its free, easy to harness and is capable to provide more energy than what is needed by most homes.

You may be aware that a commercially sold solar panel has its worth in thousands of dollars. But, did you know you can go solar for a fraction of that cost. To be specific, you can go solar for as little as $200!

Why Go Solar?

Solar panels are made up of small PV cells, also known as photovoltaic cells. The PV cells capture sun light and store it in a battery. The energy stored in the battery is then transformed into usable electricity using an inverter. Solar power is a renewable resource of energy and free to harness once you have installed solar panels.

Installing ready made solar panels can be pretty expensive and can cost you anywhere from $10,000 – $18,000 to solar power you entire home. You can solar power your whole house for a fraction of this amount if you learn how to build solar panels for home energy on your own. Building these systems from scratch is cheap and easy; all the required raw materials can be easily bought from the local electrical or hardware store. This also cuts down on any further impact on the environment as the solar panels do not go through any manufacturing processes.

Going Solar Is Easy!

Various kits are available to download from different vendors that will teach you to build solar panels for home energy. The downloaded kits include steps for calculating the actual electricity that you need from solar panels based upon your electricity bills. Once you have that information you can start building your own solar panels, typically you can easily build a 100 watt solar panel in a day very easily.

Now, that’s not something very substantial, but when you can easily redo the whole process over and over again, you can completely go off-grid with a few days of work and perhaps sell back the extra power back to the utility company. Now, how is that for a change? You’ll get a check from the utility provider!

Save Heaps!

Once you install solar panels for home energy, the panels will pay for themselves many times over the course of their life. Generally, solar panels have an average lifetime for 25-30 years requiring no to little maintenance. So, you do the math here and calculate how much you are set to save!

solar cell highest efficiency

Every day, households around the world are using up the planet’s resources for energy. If this continues, these energy sources will be depleted quickly -unless alternative renewable energy sources are utilized.

One of the energy sources that modern technology has recently put to good use is solar energy. Solar energy isn’t anything new, but new technology advancements have placed solar power more into the mainstream, and it may one day be one of our primary sources of power. -

Advantages of Solar Energy

Since solar energy comes directly from the sun, it is not only renewable, but also accessible in any part of the world. As long as the proper equipment is utilized, unlimited amounts of solar power can be collected and put to good use.

Solar power is also one of the cleanest forms of energy, since it creates no pollution, and produces no greenhouse gases or waste products. For residential uses, the use of solar power minimizes negative impacts on the surrounding environment, making it a safer alternative to wind or hydro power.

Not only is solar energy non-pollutant, in terms of gases, but it also causes zero noise pollution – since there are no moving parts in any of the devices which are used to capture the sunlight. Due to the fact that no moving parts are used, maintenance costs are low as well – only occasional cleaning and periodic battery replacements are needed. Most manufacturers of solar panels provide twenty-year warranties for their equipment, guaranteeing long-life operation.

Solar panels placed on rooftops also double as a heat absorbers, slightly cooling the top area of the house which is directly below the roof.

Disadvantages of Solar Energy

The most obvious drawback of solar energy is its sole dependence on the sun. Once the weather becomes cloudy, or night strikes, energy collection comes to a halt. However, recent advancements of technology now allow the generated power to be stored in special batteries which provide roughly enough electricity to last a night.

This is why solar-powered devices, including flashlights, are gaining in popularity and are proving to be efficient energy savers. Solar panels can also be expensive, because of the materials that are used to create them. And even when these materials are taken out of the equation, the entire process, considering the other devices involved, can be a bit costly. This includes portable devices that utilize solar energy. But most of the cost involved is in the initial purchase and installation of a solar power system – not running costs.

Fortunately, there are some people who sell damaged solar cells, which are much cheaper. These damaged solar cells can be used to build fully functional solar panels, using the application of simple do-it-yourself techniques. Although in every part of the world, there is at least some point in time when the sun shines, it is also true that direct sunlight is needed in order to make the most of the sun’s energy – and to generate the highest amounts of power. This significantly restricts the placement of solar panels. And some areas in the world may receive little benefit, due to lesser sunlight.

What’s the Bottom Line?

More research and development continues to be invested into this growing technology, and that’s a good sign for the future of our households – as solar power may one day be used more frequently than other energy sources. Of course, solar energy isn’t perfect, but it makes a great complimentary addition to other energy forms.

With all of the buzz around Al Gore’s Nobel Prize winning efforts, many are hoping the heightened awareness of global warming will turn some attention to the plight of the polar bears. It would be utterly heartbreaking if this incredible predator was relegated to zoos or worse, especially after hundreds of years of adaptation to the hostile Arctic environment. I was once lucky enough to see a family of bears in the wild in the high arctic, a mother and two cubs – it was a powerfully moving site, considering this wasn’t a refuge but actually ice flows viewed from a Russian Icebreaker. What a great many people were not aware of until recently is that polar bears need the sea ice to freeze over. This gives the polar bears ideal hunting grounds for the seals that build dens and breathing holes in on the floes. Polar bears are classified as marine mammals and are surprisingly deficient in skills for catching prey on land.

There have been several reports of polar bear migrating into the northern boreal forests of Alaska and mating with grizzly bears, resulting in a hybrid bear: http://en.wikipedia.org/wiki/Grizzly%E2%80%93polar_bear_hybrid . While this phenomenon is not entirely new, the frequency of the polar bear’s forays into southern lands is bound to increase. A bear has gotta do what it’s gotta do, afterall. Biologists fear the interbreeding could dilute some of the polar bears greatest (and least understood) adaptations, such as the ability to navigate incredible distances in a dynamic environment with few landmarks, their aquatic skills and the instinct to catch seals under sea ice.

Arctic studies have shown that over the years, the sea ice grows and recedes with somewhat normal consistency but the last few years have shown a massive recession, along with the retreat of hundreds of Arctic glaciers. Call it global warming or whatever you like, but I think the time to start “thinking green” is now-if nothing else, so the great white north stays north. We may never encounter the polar bear in our normal lives and very few people will get to visit them, but that’s exactly why we need to act now – to keep those wild places wild.

Writing and/or reading an article about polar bears isn’t going to do much good without a soliciting a reaction. With that in mind, here are A Few Resources to Help Our Polar Pals in the Arctic…

Aside from the resources above, the best thing you can do for polar bears is to reduce the effect your lifestyle has on global warming. Whether that means taking a bike to work or school, installing solar panels on your home, or just turning out the lights when you leave a room – every little bit helps.
