How Does Solar Energy for Home Use Work?

One nice thing about the advancement of technology is how things that were expensive within the past, become quite affordable as years go by. A perfect example of this is panels that convert solar energy for home use, or solar panels. These solar panels were quite expensive, but since the value has dramatically decreased, more and more people have considered cashing in or investing on this kind of energy.

Although solar electrical systems have been around for quite some time already, not everybody knows exactly how solar panels work and convert sunlight into electricity. The science behind it is complicated, but the method, however, is amazingly simple. What is commonly known as solar panels are "photovoltaic" panels, which means electricity from light. These panels contain plates that are coated with a substance that reacts with the collected sunshine, and creates a flow of electrons. The electricity is then converted by an inverter within the system to Direct Current (DC), which makes it safe to be used at home. The exceedingly solar electric system creates electricity, or solar energy for home, can be used for just about anything. It can run your lights, power your tools, and operate appliances such as your TV and radio, basically anything that needs electricity.

When the sun goes down and the solar panels can no longer collect sunlight and produce solar energy for home use, there are still other options to choose from for electricity. You can either switch back to using the facility from your electrical company, or have storage units that uses batteries that continuously enables to supply your electrical needs. However, if the system is working properly and is able to manufacture electricity, some of that electricity is diverted to your storage units. This will keep the batteries charged and ready for use. So once the solar panels are not producing electricity, then the storage system kicks in and provides you with solar energy for home use.

The electricity that these solar panels provide is safe and fairly easy to use. Once you've learned the basic knowledge of exactly what it is and the way it works, then you are well on your way to breaking your dependence on fossil fuels for your electrical needs. So why not start to take advantage of the free energy from the sun, and start saving money from your monthly electricity bill? With the way our economy is going now and prices for our necessities are continuously increasing, then the solar energy for home use will surely benefit you. But also remember that this is not the only way you can cut down on your expenses. There are plenty more ways that you can take advantage of what our environment provides us.

Solar energy panels are becoming easier to find. Chances are, you can probably find a provider that is fairly close to where you live. If not, then the web is a valuable resource for finding suppliers and even helps you find the lowest rates.

Solar Energy In Pakisatan

As solar power does nothttp://www.blogger.com/img/blank.gif make sense for all locations in the world. The initial cost of installing solar panels or other sources of solar energy is high, and that is not easy for most people to get around. No matter how much some people would like to get involved in the movement to independent energy, it is cost prohibitive.To achieve the highest level of efficiency, which is the entire point of going solar in the first place, you need the proper amount of roof space to support the panels your house may require. Not only how much space is available, but also the location of your home is also relevant to whether or not you can maintain solar energy. Some houses simply do not receive enough sunlight to produce substantial energy. This could mean that either your house is not positioned favorably in relation to a tree or other house.

Pakistan is most suitable for solar power:

As you can see, the cons of implementing solar power in your home are primarily cost and location related, but if those two items do not pose issues for you, the good news is…

If solar power is looked at through a long-term lens, you will eventually make back what you originally spent, and possibly start saving money on your investment

Let’s not forget that solar energy increases the value of your home too. Solar power is not subject supply and demand fluctuations in the way that gas is. Silicon, the primary component of solar panels, is also being more widely produced, therefore, less and less expensive with each passing year.

Solar power is independent, or semi-independent. This is great because you can supply your home with electricity during a power outage. Solar power can also be used in remote locations, places where conventional power can’t be reached. On a larger scale, solar power also reduces our need to rely on foreign sources for power.

And last, but certainly not least, it’s good for our planet! Solar energy is clean, renewable and sustainable. It does not fill our atmosphere with carbon dioxide, nitrogen oxide, mercury or any other pollutants. It is a free and unlimited source of power, unlike expensive and damaging fossil fuels.

Solar Panels

Multi-crystalline (Polycrystalline) Solar Panels
A polycrystalline cell contains many crystals. It has similar life span to the monocrystalline cell type, but it has lower efficiency and cost per watt.

Mono-crystalline Solar Panels
A monocrystalline cell is made of a single crystal. Monocrystalline solar panels are high efficiency solar panels.

How much watt solar panel we need?
Example we want to power up 5 lights of 20 Watt and we need to use these 5 lights for 3 hours every day. Here first we get a total watt usage. Ptotal = 20 * 5 = 100W. Than we multiply 100 with 3 hours. Pdaily = 100 * 3 = 300W. We are going to use 300 watt daily. Let us say we are going to have complete sunshine 6 hours each day. Now we divide 300W with 6 hours, so we will get hourly power charge that we need Phourly = 300 / 6 = 50W. So we need a 50 watt solar panel. But it is recommended to always choose a panel some bigger then we need. Because when solar panel charge the battery so it is wasting some power on charging too.

SOLAR PANEL INVERTERS

LEARN MORE ABOUT WHAT SOLAR PANEL INVERTERS DO
What are solar panel inverters? What are they good for?

Solar Panel inverters are used primarily to change direct current to alternating current via an electrical switching process. You can think of inverters used with solar panels as electronically synthesized alternators.

TYPES OF SOLAR PANEL INVERTERS
There are three types of solar panel inverters:

Stand-Alone Solar Panel Inverters
Synchronous Solar Panel Inverters
Multi-function Solar Panel Inverters
STAND-ALONE SOLAR PANEL INVERTERS
Stand Alone solar panel inverters function to change direct current (DC) from a battery to Alternating Current (AC). Stand alone inverters, which range from around 100 watts to as much as 8000 watts, are used to power a vast variety of personal or small business projects. Lower watt stand-alone inverters are often used to power laptop computers, whereas high-watt stand-alone inverters could be used to help power an entire household. In order to calculate what class of inverter you need for use with your solar panel, you will first have to determine the maximum sum of all of the Alternating Current loads in your project (or home).

How to calculate the wattage you need from your stand-alone solar panel inverter

AC_LoadDryer
+AC_LoadLaptop
+AC_LoadIron
=Total AC Load

This is the wattage you need from your stand alone solar panel inverter.
You can usually find the wattage rating on your home appliances by checking the power cable. The sum of these wattage ratings is what you need to determine the wattage you need from your solar panel stand-alone inverter.

SURGE-COMPLIANT STAND-ALONE INVERTERS
It is important to purchase a quality stand-alone inverter that has a built-in ability to surge if you are using heavy equipment, power tools, or automatic washers, dryers, and dishwashers. These appliances and equipment require a surge on startup, which your stand-alone inverter must be able to supply if you are planning to use these appliances.

SYNCHRONOUS SOLAR PANEL INVERTERS
The term Synchronous Solar Panel Inverters arises from the synchronous dynamic that such a system creates between the utility company and a personal solar-panel installation. Synchronous Solar Panel Inverters allow power generated by your solar panels to be stored in battery. If there is an excess (meaning you did not use as much power as you produced), the power is sold back to the utility company at the same rate at which you are charged!

On the other hand, if your solar panels are unable to provide you with the power you need, your Synchronous Solar Panel Inverter will allow the utility company to supply power to make up the difference. The advantages of a Synchronous Solar Panel Inverter are many, as you can see. This Synchronous Solar Panel Inverter system is quite useful - your batteries will provide you with energy during the utility company's power outages, and on bleak, rainy days, you won't have to worry about your solar panels performance, because any power you need will be supplied by the utility company via your Synchronous Solar Panel Inverter.

A final advantage of Synchronous Solar Panel Inverters is that you will not have to precisely calculate your Alternating Current load in order to set up the system. It is only necessary if you want to have complete reliance on solar panel in most scenarios, but if you are comfortable with buying a steady but small portion of power from the utility company, a rough estimation of wattage from your solar panel system should suffice with the Synchronous Inverter.

MULTIFUNCTION SOLAR PANEL INVERTERS
Multifunction Solar Panel Inverters combine the best of both worlds, and they are usually the best choice for your solar panel system. While more expensive, multifunction inverters may be your best choice. Contact your solar panel dealer for more specific information on Multifunction Solar Panel Inverters.

TRUE AND MODIFIED SINE WAVE INVERTERS
An inverter converts a direct current to an alternating current through a delicate electrical switching process. This process makes an inverter function as a synthesized alternator, which are typically used to produce AC current by creating a smooth alternation, similar to a pendulum gently swinging. This alternation takes the form of a sine wave, which is the ideal wave pattern for transmitting AC power.

MODIFIED SINE WAVE INVERTERS
Modified Sine Wave inverters are better in typical solar applications when electric motors are not involved. They are not quite as efficient as true sine wave inverters, but you'll find that they are much more affordable. Unlike true sine wave inverters, modified sine wave intverters produce a stepped waveform, which isn't really a sine wave at all.

Because the current is not alternating perfectly, the stepped waveform of the modified sine wave inverter causes the inverter to generate an irritating buzz. Take this into careful consideration when purchasing an inverter.

TRUE SINE WAVE INVERTERS
True sine wave inverters are very efficient and have a very accurate waveform to the true sine wave. True sine wave inverters are a little more pricey than modified sine wave inverters because of the reduced noise and their strong compatibility with certain devices, such as electric motors. This is the better option if you value silence, or want optimal performance from electric motors, such as those found in an electric water pump.
