Solar Power: How Does Solar Energy Work?

Saturday, July 3rd, 2010

Many people today want to conserve cash on their energy bills and one of the most famous methods is through utilizing solar power. So how exactly does solar energy work?

Energy coming from the sun in the form of heat as well as light is abundantly accessible to everybody on Earth, even in places that don’t get a lot of sun. Did you know that the Planet receives a lot more power from the sun in an hour than our entire population is able to use within the whole year? With all that clean, renewable energy that is coming from the sun every single day, it is worthwhile to find out a way to use it.

Active Solar

There are two different types of solar power you can use to power our own houses as well as daily lives. One is active solar energy, which works through solar panels, which are setup with the use of photovoltaic cells. These cells are connected together in order to produce electricity.

Just how much electrical output they produce depends upon several factors. One of them is actually the number of cells are linked together in a panel, and just how many panels are now being used.

The power from the sun comes in the form of direct current, DC, instead of the alternating current, AC, that is used in your home. For this reason you’ll need a way to convert the energy. The simplest solution is to purchase a power inverter, which usually transform the sun’s energy in to usable AC elecricity. One more alternative is to convert your house’s electric needs to DC power, though this is generally impractical particularly in existing homes.

Thermal Solar Energy

There’s another type of active solar power which makes use of thermal energy from the sun’s rays to heat water in your home. Devices that circulate and pump the water help with keeping it warm. Subject to where you reside, solar power can heat water as much as 60 degrees or more. Although this may not be ideal for taking a shower, it may be effective for dish washing or perhaps doing your laundry. Solar power for heating water may cut your water heating bills substantially, and may be used in combination with solar electricity.

Passive Solar

Passive solar energy uses the power of the sun without the use of any mechanical devices. When you’re out on a sunny day, you are feeling the warm sun’s rays, and this particular process is really similar for heating your home. A passive solar house has south facing windows and also uses building materials which absorb the sun’s rays and then dissipates the actual heat straight into your home effectively. Passive solar can also be used to heat water in our home.

Using Residential Solar Energy

Solar electricity is a great alternative to powering your home using standard power grids. It is already being utilized in a variety of household, and also business applications worldwide. There are lots of various methods for you to get a home solar power system, such as DIY solar power kits which come complete along with diagrams and materials you need to construct your solar power systems for not much money.

You may also find solar energy professionals that will come to your house, assess your needs, and also accomplish all of the work for you. There are even ways that you can get used solar power panels for free, or through solar power grants or renewable energy programs in your area.

You can run your home on solar energy even when there is minimum sun. Utilizing batteries to store excess energy, you can draw from these through the times when there is simply not enough sun to be effective.

Factors In Selecting Home Solar Power Systems

Wednesday, June 30th, 2010

What exactly are home solar panel systems? The primary purpose of a solar panel is to transform sunlight in to usable electricity. This effect is a physical manifestation of the photovoltaic effect. Solar panels are comprised of solar cells which are gathered together within a frame. Every solar cell has the capability to transform the sunlight in to useful electricity. However, the conversion rate of each cell is somewhat limited when measured in total wattage output. Basically, every cell only produces an amount of electrical power equivalent to 1 to 2 Watts. For that reason an extremely large quantity of solar cells need to be built-into each solar panel, and usually a significant number of panels are linked in order to form a so called solar panel array. This process is essential to produce a usable volume of solar energy for a complete home.

This joining of solar cells collectively in order to establish higher power is an inherent advantage of the solar cell system. It follows that after you require additional power for personal consumption, you only have to add more panels.

There are many kinds of solar power panel, which have various power generating characteristics ad functions based mostly on the material from which they’re made. They can be comprised of either thin-film, monocrystalline, or polycrystalline modules. The Thin-film solar cell includes alloys (amorphous-silicon) which are stored in thin layers deposited on a substrate. This means it may be quite supple (determined by the substrate used) and it is therefore more easily applicable in certain environments.

Monocrystalline, however, is created from one silicon crystal rod and can be regarded as having a rigid structure. The silicon rod is cut into thin wafers to be able to provide the base within which solar cells are formed. Polycrystalline solar cells are processed from numerous silicon crystals which are heated collectively, and then cooled down in molds to create ingots of silicon. The ingot is then cut in to wafers and processed as before in order to produce solar cells.

The efficiency of a home solar power panel is measured by the number of the output and input power. Normally solar power panels return an efficiency range of from around 10 % to about 19 percent. As might be expected, the higher the efficiency rating obtained, the more likely the cost of each panel will also be higher. When preparing a new installation therefore, it’s important to take into account initial installation costs against better long term efficiency savings in order to make the best choice for you.

Identifying the right solar power panels therefore requires an understanding of some specific parameters. These parameters will help you decide which solar panel to use in your application. Three essential measurements to be familiar with consist of ‘efficiency’, ‘rated power at STC’, and ‘rated power per square foot’. ‘Efficiency’ is the ratio of the output power of the solar panel to the input power of the sunlight hitting it. ‘Rated power at STC’ measures the sum of output in watts from the panel under Standard Test Conditions. ‘Rated power per square foot’ is the power output of the solar panel at Standard Test Conditions per square foot of the panel’s surface.

Lastly, modern home solar power panel designs maximize the generation of electricity from solar energy and are now a very workable option if you would like harness this type of ‘renewable’ energy to satisfy your personal home consumption.

Solar Energy - Home Solar Power Systems Purposes

Sunday, March 7th, 2010

Many individuals believe that home solar power systems are eventually gonna take the place of fossil-fuel based energy sources as the way that a lot of people power their homes. This free and never-ending method to generate energy is a better method to produce electricity for your own home, and it is more affordable than ever.

Thus, what is the most crucial thing that you must know about residential solar power systems?

Can you imagine that there’s a power source in existence that is powerful enough that the quantity of energy that’s absorbed into the earth, sea, as well as atmosphere each hour is greater than the entire level of energy that mankind used in the whole year of 2002. That’s what MIT’s publication Powering the Planet: Chemical Challenges in Solar Energy Utilization says. The energy that the earth absorbs comes available as heat and light, and the introduction of residential solar power systems means that the average citizen and homeowner are now able to put that power to use!

Nevertheless, the most crucial thing you should find out about household solar power systems is that one could continue making electricity as long as the sun keeps on shining. Even if everyone had one of these awesome systems, you wouldn’t run out of energy. These types of systems aren’t accessible to home owners in the form of photovoltaic solar cells, which will convert sun energy into electricity. The solar cells that many people use for their at-home solar power systems usually are set up into a solar panel.

These types of solar powers are usually set up in different ways in accordance to the vicinity in which the home owner lives as well as where the actual panels are mounted on the home. Positioning solar cells in an area where they will receive the most exposure to the sun as well as angling them in a way that they get the best exposure will guarantee the most quantity of electrical energy going into the house. This is referred to as concentrated solar collectors. Non concentrated solar collectors are usually collectors which are situated in places with much less direct sunlight, and may absorb solar power from direct angles, as well as reflecting angles.

Solar powered systems could both heat the house as well as provide electrical energy for the household. You can also use them to heat your swimming pool!

There are so many benefits, and so few drawbacks, to getting a solar power system for your home which any other sources of energy seem to be like a bad choice. Thus, why haven’t more individuals been using them? Especially right now, in a world where the weather is actually changing rapidly, and the environment is more polluted than ever, and fossil fuels are starting to cost an arm and a leg?

Definitely, many people are nervous with regards to not having ample sunlight. If the sun’s not out, then your solar panels can’t collect energy. It is not always sunny. And also, despite the fact that fossil fuels have gotten far more expensive recently, these fuels are still more affordable as compared to the money you will pay for solar powers.

And last of all, in the event you do reside in a sunny enough area, you then might even be able to use your home solar power systems to generate excess power, that you can then offer back to your power company as you wouldn’t be able to utilize it.

Daily, the huge benefits of solar energy systems for the household are getting increasingly more evident. Our society has become more and more energy conscious every single day also. Despite the fact that fossil fuels continue to be obtainable, solar power is free and also obtainable so long as the sun is out, and the production of it can’t be controlled by companies or the government.

Solar Power systems for the home are a power source which is environmentally friendly, and will sooner or later be less expensive since much more people start wanting to use it. Whilst fossil fuels will simply get more costly as long as people continue buying it. These home systems can help you save tons of money when it comes to conditioning your house’s air.

There are also tax breaks in a few states or countries for people who possess such systems for their residences. These types of tax breaks alone could make it simpler for you to afford a system for your residence.

Take advantage of the amazing new solar technology offered to you today simply by installing a solar power system in your house. You will be happy you did.
