Solar Power Worldwide

Solar energy is not solely used in the United States. There are many other countries that utilize solar energy more effectively than in the US., in fact, solar powerworldwide is huge and some of the more effective uses of it are in other countries.

The U.S. is finally delving into the global solar market. For example, California and Colorado are two of most aggressive states in bringing solar power online. However, many other states are moving towards making solar power more accessible, feasible, and affordable. These moves are echoed in many countries around the world.

Experts in Europe and Japan are custom-building photovoltaic panels as atriums and skylight walls. The panels are built into new construction in order to provide the energy needs of the building. Additionally, in Japan, there’s a high-rise building that was constructed with a photovoltaic outer surface to produce energy.

The preferred design for solar powered systems in Germany is a generating container of photovoltaic cells. It is similar in shape to a shoebox. Nine buildings inside benefit from the solar energy that is generated.

There are many field military units that are using solar power worldwide. The modules can bring electricity into the most remote areas of battle and they don’t weigh a lot so are easy to transport. The enemy will not be able to spot them very easily, as they are designed to minimize any reflection.

In numerous third-world nations hybrid solar power systems are utilized to provide power to small medical clinics. This makes it easier for clinics to operate on sunny days. A backup generator is used on cloudy days and at night. This system allows a lot of needy people to receive adequate health care.

India recently brought in and installed solar power on some houses. Some families purchased TVs in addition to the many other uses they found for the electricity. Televised cricket events and other television shows are being discovered and enjoyed there. Now, they can be aware of the happenings around the globe.

In the same village, there has been an overall improvement in quality of life due to the availability of solar energy. For example, students can now use bright lights for studying. Thanks to solar power, women who used to be forced to cook before sundown can now do it after dark when the mealtime should be.

In countries around the globe, solar power is used for many agricultural tasks. For instance, energy for water pumps is used for irrigation.

South African scientists are discovering forms of solar power that are more effective than the ones crafted from silicon. These panels are less expensive, also. This will allow for the continent to develop many advances in this technology.

We should look to using solar power whereever we can – which is basically anywhere. Solar power can assist underdeveloped countries. Developed nations should not be slow to embrace it either. Through the collective work of all nations, clean efficient solar power will have a lasting influence and by using solar power worldwide, we will be helping the entire planet.

Solar Power Safety

Solar power is considered to be a reasonably safe energy source. However, there are some solar power safety procedures that you should follow when you are working on some parts of a solar system. In particular, the batteries and solar panels require special attention.

When you are working around your solar power system batteries it’s a good idea to make sure there is someone close by in case you need help. Here are many reasons why this may be a good idea.

Automotive and solar batteries both contain battery acid. If your skin, eyes, or clothes comes in contact with the acid, you need to flush it off immediately.

Keep soap and water accessible in case you come in contact with battery acid. If you get it on your clothes, remove them immediately before the acid eats through them and gets on your skin. If you get acid in your eyes, flush them with water thoroughly and then seek medical attention immediately.

When working on the batter make sure you have the backup generator turned off.  Any little spark can lead to an explosion.  This means also to not smoke near the battery or allow any flame drop near the battery.

Removing metal jewelry or watches is another important part of solar power safety when you are next to the battery. A short circuit can cause the metal to fuse together possibly causing you intense burns.

When you are working on the solar panels there are also some safety procedures you should follow. First, in order to prevent them from producing electricity while you are working, you should cover up the panels so they cannot receive any sunlight.

You need to be cautious what you touch during solar panel installation. It isn’t safe to touch the terminals when they are exposed to light. You should also use insulated tools to work on the panels.

Don’t work on solar panels in the rain, as they do produce electricity. Also be careful because sparks may occur when you work in the panels. It’s also a good rule not to have flammable gases near the panels.

Children should never be allowed to play in the area where solar panels are being installed, as an unsecured solar panel may fall and break.  Beside the danger of the falling panel, there is the hazard of broken glass.

The installation and maintenance of solar power are the areas when most of the solar power safety measures should be practiced.  When compared to other energy types, solar power is still considered to be very safe.  It doesn’t take a highly trained professional or many precautions to ensure the project runs smoothly without any injuries to yourself or others. Most people find it so simple that they need little help, if any at all.

The Cost Of Solar Power For Your Home

There is no easy answer to what the cost of solar power for your home is.   It’s very hard to nail down an accurate answer as there are many different variables to consider.

The primary cost is the initial purchase and installation of the solar energy system.  You have to know several things to know what kind of system you need.  These will differ depending on  whether your home is being build new or already existing.

Your home may already be on the utility grid.  If so, some information can be gained by viewing utility bills from the previous year.  Investigate how many kilowatt/hours you consumed during the different seasons.  Take the price you pay per kW/hr and multiply by the kW/hrs you used during the different seasons.  This should give you the amounts of the bills.  This is a way to show you how you spend your money.

There are online estimators available that can help you get an idea of how much the system you need will cost. These are generally good resources to use. On the downside, they are not available for all states. Regardless of whether or not you use them, you should also consider hiring a professional for an estimate before you finalize your purchase.

The estimator will ask you where your house is located, state and county.  This will assist figure out how much sun the house will get every day on an average, as well as show the climate so the power needs can be determined.

To figure out the cost of solar power for your home, you will also need to enter past power usage.  You will need a  professional estimator if you’re your home is new.  They will determine from all the info how large a system you will require.

Let’s take for example your needs require a system for your home that costs $20,000.  Tax incentives and rebates might allow you to pay less than $15,000.  To determine if the system will pay for itself, more complex calculations are required.

This involves differences like net-metering and the use of batteries for energy storage to be used later when it is cloudy or at night.  They involve determining how much you will pay per kW/hr with your solar power system.  Then, you can compare the savings.

The saving probably won’t be much until the unit pays for itself.  Your solar system will get even cheaper by comparison when inflation raises the price of utility power.  When the system has paid for itself you will then really experience the cost saving.  A system has about a 25 year lifespan and usually pays for itself in ten years.

There is no easily available flat answer as to the cost of solar power for your home.  To get a good figure, you need to hire some professionals to research your particular needs.  I you do go solar, however, you will probably find it is well worth it, not only for your bank account, but for the environment too.

Solar Power Cells

Calculators that run on solar power aren’t new. But before solar cells were used in consumer devices like calculators, they were used in space. Today, more and more uses are being developed for solar power cells and how they work is intriguing.

Photovoltaic cells are made from a semiconductor, often silicon, which gathers energy from the sun.  When the light hits the semiconductor, electrons break loose and are pushed in the same direction forming an electric current.   To harness this electricity, photovoltaic cells are connected to a circuit which begins at the top, sends energy through the appliance, and back toward the contacts at the bottom of the cell.

Very little movement of electrons is possible when silicon is in its natural crystalline state, so the silicon is actually impure.  Individual silicon atoms each possess four locations to which electrons can be bonded and so are relatively unstable.  But each atom typically joins to others through the sharing of electrons in their outer valances.

Silicon is not as conductive in its original form, so to get the most energy from the solar power cells, N-type silicon is used.  It is created from a reaction combining silicon with phosphorus.  The result, a free electron is available for each phosphorus atom joining with the 5 outer ring silicon electrons.

Doping silicon with boron results in P-type silicon.  The outer shell of the boron atoms have only three electrons, leaving a “hole”, which is a place into which  an electron can move.  In photovoltaic cells, one combines P-type silicon with N-type silicon.

Two different types to silicon need to be set up side by side.  The first thing that will happen is the holes and electrons begin to fill in at the shared border.  You will know when equilibrium is reached once the electrons can’t interact in that way anymore.  The two halves will separate, creating an electric field.  At that time, it will be easy for the electrons to flow from the positive side to the negative side.  However, the electrons that are already in the negative can’t flow back to the positive side.  You’ve created a one-way flow of electrons.

Photons consist of energy units from the sun, and they make energy by making contact with the atoms of the solar cell and freeing holes and electrons.  This continues the movement of electrons between holes and establishes current.  Voltage results from the field created at the site of the P-type and N-type silicon junction.

Harnessing the energy from the sun through photovoltaic solar power cells is still essentially in its infancy.  Both commercial and residential settings are seeing the benefits of using the power of these cells.  Anyone willing to do a little research and take a little time can grasp the concept of photovoltaic cells.  Using the power of the sun through photovoltaic cells makes solar power a real possibility.

Advantages Of Solar Power

Many people, most notably those residing in remote areas choose to use solar power systems that are completely self-sufficient. Systems that are designed to provide all energy needs at all times. In contrast other people favor enjoying the advantages of solar power while still remaining on the utility grid.

With inverters that produce pure sine waves as part of the solar power system, the system may be attached to a utility grid most of the time.  This lets consumers have the backup for utility power as opposed to using storage batteries.

Connecting to a utility grid helps those utility customers who don’t wish to have a big solar system on their homes.  It also helps in situations where there just isn’t sufficient sunlight to give enough power every day.

Several benefits are gained from being part of a utility grid. One involves net metering.  This program is widely offered.  It lets utility customers with solar power systems see profits resulting from excess energy output.

Net metering works very simply.  Whenever the solar power system puts out more energy than the home uses, the consumers get credit for this on the utility bill.  Sometimes this won’t amount to cash rebates, but credits will be used towards current or future electric bills.  Sometimes, though, there may be a catch-up check at year’s end if you’ve produced more than you ever used.

Another important thing for users on the grid to monitor is Time Of Use  (TOU) net metering.  This is accomplished by putting in special meters that measure time of power usage from a grid.  Since the power off the grid costs more during peak hours and seasons, the meter keeps track of the usage during no peak and peak hours.

When you know the peak times, you can  use the advantages of solar power to save you money during these times.  Whatever can’t be done by solar power during the peak times can be completed during the off-peak hours.  For instance, water can be cooled for air conditioning in advance.

Most people feel that battery storage is critical for their systems because they don’t want to go without power in case of an outage.  This is very true in states that have a lot of blackouts.  This is the main reason why people insist on having a battery backup system.

Banning of the use of solar power systems with battery backup on some grids has been discussed.  Thus far net metering has won out, with or without the use of batteries.

Anyone can have the advantages of solar power along with the piece of mind of traditional electric by going on the grid.   While some people feel that solar power itself can only grow if people go to a totally solar system, I think that converting to mostly solar is a big step in the right direction.
