solar scienceWith technology and cities emerging, there is a growing need for more power. Our current energy supply, however, is not enough to meet the increasing demands of the population from all over the world. This is reality, especially when we are highly dependent on non-renewable energy, like fossil fuel. This is why more people are looking for a sustainable energy source.

Solar power is among these sustainable energy sources. This is also one of the most preferred alternative sources of energy since it is abundant in most countries in the planet. Although the solar power is a good idea, there are many solar power pros and cons that you should know. This will help you in deciding whether a solar panel is right for you or not.

The following are some of the solar power pros and cons, and aspects that you can use to weigh when planning to buy solar panels.

Environment-friendly

Solar energy, unlike the traditional sources of energy, is good for the environment. It does not produce any by-product, like carbon dioxide emissions, and does not cause any pollution. It is also a renewable source, which can be used again as long as the sun keeps shining. Everyone can make use of solar energy without depleting it.

Independent

With solar panels, you don’t have to depend on an electric company as your source of energy. Now, you can manage your power supply at home. You can charge your panels as long as you can or stop it anytime when you’re not at home.

Money

Using solar energy can mean more savings for you in the long run. As long as you are using solar energy for the next couple of years, you won’t have to worry about paying your high electric bills.

As for the disadvantages, these are several factors that you have to consider. Although these aren’t necessarily deal breakers, you also have to take a look on some of its drawbacks.

Initial Investment

solar moneyAlthough money can be classified into both solar power pros and cons, let’s discuss it as a drawback. Utilizing solar energy will require an investment. You’ll need to purchase solar panels, which can be a bit pricey as well. It is not really an affordable alternative since you’ll have to make a high initial payment with the equipment that you’ll be using. The price also depends on the kind of solar panel and its power capacity.

Setup

Setting up the equipment for the solar panels may require technical knowledge, especially if you are thinking of doing it all by yourself. The equipment may also take a lot of space. You’ll need a large space where you can install the panels and another space for the regulators and monitors.

It is important that you know the solar power pros and cons so you can examine whether it will suit you and your needs. Nowadays, more and more people consider solar energy as a great energy alternative for them.

Solar Power Facts and Technology Expansion Needs

Expanding on Solar Power Tech

 

solar panel arrayIn the inventory of solar power facts, the present use of solar energy world-wide is pretty low. Even with the new developments in technologies related to better solar power use, many experts agree that the total use of this renewable energy is only a measly 1%. (We lose 99% of the sun’s energy everyday.)

Unfortunately at this time, the world still depends on traditional energy sources (oil and coal) whose dwindling supplies are looming. There is some progress in the growing development of other cheaper sources (wind, water, biofuel, and others) but it has not kept up with today’s massive demand on power.

Stored Solar Power

Topping the list of solar power facts is the knowledge that our sun is the main source of all the energy on earth. The energy we get from our food is simply stored energy in plants and animals we consume.

All the fossil fuels we use (oil, coal, natural gas) are stored energy accumulated from the remains of dead plants and animals buried millions of years ago. Even nuclear power (stored in uranium deposits) came from the sun.

Faced with all these, one awesome item in our solar power facts reveals that the amount of direct solar energy we get in six months is equal to all the combined energy we get from all sources (coal, oils, and others) ever since.

Future Prospects

Experts agree that the main costs of discovery, retrieval, development, and delivery take up much of the expenses in our energy economics. This is over and above the point that they are non-renewable and fast diminishing.

One fortunate item in our solar power facts list is that direct acquisition of solar energy is now feasible, however young the technology is (solar panels, solar thermal technology). Once the engineering hurdle is surmounted (or maybe some future discoveries in technology), costs go down.

Solar Panels: What are They?

What are Solar Panels?

When talking about alternative sources of energy, solar panels are always a part of the conversation. However, most people would ask? This term can be a bit confusing.

solar installSo, what are solar panels? These are installations that are composed of many solar cells. These little cells absorb the solar rays in the atmosphere and then convert them to usable energy. The raw energy that the solar panels generate is then made usable through a conversion box that makes it safe for electrical equipment. Raw energy is not safe and usable for our electronic gadgets, even for those used for industrial purposes.

Maybe you’re asking again: what are solar panels and how does the sun affect its operation? The solar panel is dependent on the amount of sunlight available in a given time. This can also affect the output produced by the solar panel. A rainy weather will definitely reduce the energy for consumption. The same thing happens on an overcast day. The solar panel can still absorb sunlight in an overcast or rainy day. However, these won’t be enough to power the day-to-day activities even at home. This is one of the disadvantages of the solar panel. If the sun shines bright throughout the day, then you’d have an abundant source of power.

A single cell has a low output. When combined with a huge solar panel, this can provide ample energy to support a home. However, the output of a solar panel will also depend on the size, quality, and the number of the solar cells. What are solar panels and on what scale are they used? A usual solar panel has dozens of solar cells. Solar panels for home use are small in size. These are enough, however, to power the simple home appliances and give energy to be used for day-to-day activities. Industrial solar panels, on the other hand, are huge and have a very high output that can provide power to heavy duty machines. The solar cells that are in these industrial panels are expensive and compact. They have a bigger energy output compared to the common solar panels used at home, which makes them perfect for activities that require intensive power.solar house

Different solar panel models and types can also yield different results. The output will depend on the model and the kind of power cells that these solar panels have. The cheapest solar panel won’t really have an efficient power supply. This being said, it is important to do a little investment and purchase solar panels with better quality. If you want to get better output, then it would be wise to spend on the solar panels and the equipment. However, you don’t have to purchase the most expensive solar panel available. Remember to stay within your budget. Focus on the performance and the durability of the solar panel.

Now, you can already answer the question on what are solar panels. You need not be confused since it’s just simple. The solar panel is an interesting and useful piece of equipment to many people and industries.

How Solar Panels Really Work

The Science behind how Solar Panels work.

how solar panels workElectricity is one of the most important, if not the most important utility men can’t live without. It has become an essential part of our lives. But nowadays, electricity charges have climbed continuously, making it such an expensive necessity. The good news is there are actually many sources of power that you can use as an alternative. These come from natural sources such as the wind energy generated by windmills or the most common of them all, heat energy from the sun. Electricity generated from the sun is called solar power. Sure, everyone knows that. But what most people are unaware of is how solar power works.

Whatever solar-powered device you’d like to use, all of them utilize the same concept to produce electricity. It’s almost similar to that of an outlet or batteries. In all cases, the power comes from the free flow of electrons in a circuit.

solar houseTo fully be knowledgeable on how solar power works, let’s have some flashback from our high school chemistry. Pure silicon is known as the basic component in solar panels, same as that used in computers. Silicon, when bared of its impurities, becomes a perfect neutral surface for electron transmission. Silicon has eight electrons in its outer shell but carries only four to have a neutral state. This means that there is still some room for four more electrons. When one silicon atom connects to other silicon atoms, both will take on each other’s remaining electrons. This is a strong bond, resulting from years of combination in order to create a big piece of pure silicon. This pure silicon is then used to assemble solar panels.

This is where science becomes part of how solar power works. One should be aware that solar panels are made by the union of silicon with the other elements to create either negative or positive charges to generate electricity. An example of this process is if silicon combines with phosphorus. Since phosphorus has five electrons, it gains an additional electron aside from the eight electrons needed. That one electron cannot be left behind because it is bonded with the other phosphorus electrons. This means that the silicon-phosphorus plate is negatively charged. In order for these to produce electricity, silicon must also be combined to other elements. This would then create a positive charge. The two plates will be combined together with conductive wires between the two. The sunlight will send out energy particles called ‘photon’, which acts like a hammer in constant motion. Photons break the electrons present in the solar panels, thus generating electricity. This is how solar power works.

Solar panels have their pros and cons too. Same as other materials, it also has its own set of weaknesses. They may appear big but they generate only a little amount of electricity relative to other sources. The bigger the item that needs solar power, the greater the number of solar cells it would need. One factor that lessens the life of solar panels is infrared waves. But overall, it’s still a good alternative and a great way to help save the environment.
