Advantages And Disadvantages Of Solar Energy


Solar energy offers with it the potential to eliminate an over-reliance on carbon burning sources of fuel. Within the United States, such a shift in energy production would represent a great deal of change as countless energy interests fight for a place of relevance in a future energy market. Putting politics and special interests aside, lets take a moment to carefully review the advantages and disadvantages of solar energy. Designed strictly for the purpose of edification, the conclusions you draw from these finding are entirely your own.

The Advantages Of Solar Energy

1. A Renewable Source Of Energy

Solar energy harnesses the power of the sun to create an infinite source of electricity for use. While fossil fuels are ultimately finite in nature, the sun will guarantee billions of years of potential electrical energy as it continues to burn.

2. Friendly To The Environment

Along with being finite in nature, fossil fuel when burned creates a great deal of CO2, which has been shown to have a myriad of harmful effects to people as well as the environment. A focus on alternative sources of energy like solar could help to reduce the need to burn these fuels, decreasing the rate at which we destroy the environment.

3. Does Not Produce Noise

Solar energy, unlike any combustion engine or traditional power plant, does not produce noise as it generates power. In addition, the fact that it does not generate noise makes it better then other clean alternatives, like damns or wind turbines.

4. Is Available In Its Purchase And Use In Many Places

Solar panels are available across the United States as well as in most places in the developed world. With such easy access, it is no wonder that the vast majority of locations can also benefit from solar panel. Considering the success with solar that has been had in several parts of cloudy Germany, and it becomes evident that even when sunlight is reduced, energy is still created.

5. An Abundant Source Of Energy

As stated before, the sun is not going anywhere. As long as there is no constant cloud cover, solar panels will work to create a continuous stream of power from the sun. Whether you are using them to help power a city or reduce your own energy usage, solar panels can produce an admirable amount of electricity.

6. The Underlying Technology Is Improving

Every few years the underlying technology behind solar panels improves. Along with driving down the price, these improvements help to boost the power production, making solar panels an increasingly smart decision in the years to come.

The Disadvantages Of Solar Energy

1. It Requires A Great Deal Of Space

A large number of solar panels are required to meet the electrical needs of a small town. When serving an even greater population, the area that solar panels take up becomes substantial. While this may not be a problem in places where arid or desert landscapes are abundant, they become a problem in parts of the world where either uneven terrain or a lack of flat building space limits solar energy placement.

2. It Does Not Always Produce The Same Level Of Electricity

Solar panels are great for producing electricity, but they are not the most reliable sources of electricity out there. For example, if you are in an area where there is snowfall, then expect the snow to block any winter light and energy production from the panels. In addition, cloudy days can have a noticeable affect on the energy produced in any given day.

3. The Expensive Is Pushed To Storage

Battery storage represents a sizable expense that must be considered when installing a set of solar energy panels.

4. Requires The Use Of Numerous Exotic Materials

Whether it is the materials that go into the solar panels themselves or the material in the battery, either will require exotic materials. These exotic materials will require energy to produce, refine, and install into a working component that you can utilize for solar energy production.

5. Many Government Subsidies Are No Longer Available

Government subsidies come and go. While they have helped to spur on the development of the industry, many of these subsidies are being faded out.

6. Production Of Panels Causes Pollution

As stated before when examining the affects of creating the solar panels and the exotic materials used, the production of these solar panels produces pollution at every step of production and transportation.


Solar Backpacks – Should You Buy One ?



We simply cannot live without our phones and tablets. Keeping them charged and working for the entire day can be quite a challenge. As phones get smarter, they consume more and more battery life. With the use of mobile internet, it can get even worse. For people who are constantly on the move, this can cause some major anxiety. Good thing solar backpacks were invented! They offer one of the best solutions to charging gadgets when you simply do not have access to an outlet or power stick.

How It Works

Each solar backpack has a built-in solar panel that converts solar energy into regulated power, which can be used to charge almost any mobile device. There are two ways to charge a device: it can be plugged directly to the cable connected to the solar panel or you may use an optional rechargeable powerstick to charge it later.

Types of Devices

Solar backpacks can charge most types of mobile devices such as smartphones, tablets, digital cameras, video cameras, game consoles and even laptops. For campers or those who live in remote areas, they are useful in giving necessary extended power to FM radios and portable lamps.

The usual charging time for a solar backpack ranges between two and four hours on a bright and sunny day. It can give you one full charge on a smartphone. Charging times will increase accordingly in cloudy or low light conditions. It may also depend on how large your gadget’s battery is. For those who own smartphones with larger batteries (e.g. 3,000 mah), charging will definitely take much longer. The good news is that it should get you through the day or at least until you find an outlet where you can plug your device.

Options available

When buying a solar backpack, it is important to make sure the thin-film photoelectric solar panel is built well and does not look flimsy. It should not add weight to the bag so it can be used as normal.

Since most of us own more than one gadget these days, it is best to look for ones with several cable options. Standard ones include 2-3 adapters but pricier solar backpacks can include up to 8 adapters for iPad, iPhone, USB-devices, and more.

Perhaps the most important thing to take note is that it is still a backpack! Utility is as important as its charging power. Standard ones have a multiple sections for laptops and other stuff such as your books. Smaller pockets can accommodate other smaller gadgets like phones and MP3 players.

Design choices may vary. Most people would probably prefer backpacks where the solar panels are incorporated into the design. Others turn from backpacks into messenger bags with just a quick change of a strap. While messenger bags and tote bags are also available and increasingly popular, you will get more charging time with a backpack due to the position of the panel on your back.

Should you buy one?

Unless you are an outdoors-type of person, waiting for your phone to charge under the heat of the sun may not sound like a great idea. It should be great for campers, hikers or people who like attending festivals and outdoor concerts. Students can definitely take advantage of getting some extra juice for their tablets or laptops during their breaks.

The size of these backpacks may appear clunky to some people. However, the benefits help anyone look beyond that. Anyone who wants to any available option to charge their phones on the go must consider having one.
