Who is a Solar Energy Contractor ?

A solar energy Contractor is that contractor hired by a owner of that unit which can blankly depend upon the complete installation of the solar cell electric unit and uses upon productive measures to safeguard the installation amount of the client thereupon. It is the wholesole responsibility of the contractor itself to choose abrabded solar product of the market with no substitutes or duplication processes and have the rights with complete credibility towards the client if in case the product turns out to be inferior or might fail in the long run because usually when a specific contractor is hired to specifically poduces a 100% output of the electric cell solar unit its working capacity is more then what the client can purchase himself from the domestic maket with less or no guarantee of the purchasing done thereupon therefore with hirinf process the client somewho gets insured of the item and can also lay the blame on his shoulder as what could have gone wrong or why the contractor is taking so much of time in installing the unit sooner or later.

There are mainly various interconnected sophisticated components that are fragile by nature and a little bit of lacklustre behavior could takes it toll over the client who is ready to purchase the unit sooner or later. It?s the duty of a hired contractor to specify every sophisticated component of the solar product to the owner with descriptive analyses as to what could happen with the stipulated guarantee of product working for years and the cost of maintenance equires for timely over-hauling of the defined solar unit. With the helpof a contractor the component can be replaced easily as what it might take more time by the cutomer itself. The working procedures of the contractor could be learned broadly according to such terms mentioned: There are different varities and sections of solar unit system such as: A complete ?Stand alone solar system? is economically excellent. The system is used primarily for RV systems; cabins; backup; lighting and for portable power systems. The Photovoltic array size (solar panel numbers) and battery will wholeheartedly depend upon individual power requirements. The solar panels charges up the battery during daylight hours and the battery thereby supplies power to the inverter for improved productivity of the unit. A contractor could recommend to have 2 inverters to supply for AC house current which might becoe necessary to power up large loads used upon for air-conditioners. The two could be demanded as one can wok while other has gone for servicing or repairing work. Certain clients hire contractors because they possess more knowledge and information about the fickle climatic conditions because a particular client might never know prolonged adverse affects of the fickel climatic conditions.

A contractor could also recommend for extra battery storage if in case the system doesn?t work in the first instance. The other basic but important components to be installed in a solar panel unit might consists of charging controllers; cells; arrays; inverters; wirings; etc. A solar panel unit contractor should be an expert to know upon the type of enewable energy source a client demands with years of practising up of installations of such units commercially. A contractor can also be asked about another specific manufacturing enterprise for such products or othe industrialized labors who are the experts working as a team for the contractor. The warranty and service policies are offered by competing bids.

Various Ways Of Storing Solar Energy

Solar power is one of the greatest accomplishments that people have made in the world of technology. Hundreds of people have placed their time and energy into learning out how it works and how it has the power to assist us with our average lives. They have learned that it can be employed to light up homes, warm them, and supply them with the water they need.

Numerous of us are fascinated by the technology that is solar power – but hardly any of us realize exactly how it has the ability to hold all of the energy that the solar panels accumulate. All of the energy is from the sun – which is why you are not able to gather it during the evening hours when the sun is covered from us.

Because of this special devices had to be made that would be able to store it for numerous hours and with little troubles. There are thermal mass devices that can hold the electricity in the form of heat for ordinary temperatures or for particular seasons.

These systems are most commonly developed with things that have the ability to resist high heat. This includes earth, stone, and water. Some of the more special and well developed systems have the power to lower peak demand, lower the heating and cooling demands, and shift the time it is supposed to be utilised during the off peak hours.

The phase change materials are also utilised for thermal storage and are some of the most low-cost kinds. They are more general for residential homes where they are easier to get a hold of and to put in. These materials include Glauber?s salt and paraffin wax. The first Glauber?s salt solar power heating system was employed in 1948 in a house in Massachusetts.

Molten salts are utilized to hold solar energy at high temperatures. This is essential for storage medium and are more valuable because they are not as expensive and able to stand firm against some of the most severe heat temperatures. There are also off-grid PV systems that utilize rechargeable batteries to contain extra amounts of electricity.

Advantage of a Solar Energy House

There are many people who are not worried about their energy bills. In fact a few of them have arrangements with their banks to pay their utility providers directly. One fine morning such people will be surprised, that is if they bother to check their bank statements. The fact is that most such people hire accountants to undertake mundane tasks like going through bank statements. All that these people do is to sign the account statements prepared by their accountants. These people will, at one stage of time or another, realize the value of a solar energy house, when they eventually check their utility bills. They do not know that the costs of electricity have jumped up by leaps and bounds.

The utility companies announce such increase in prices in their bills, but one has to glance at these bills to know about the impending increase in costs. Unlike these people, there are another group of people who have value and respect for their hard earned money. They know that the power costs are getting out of hand and they search for alternatives like sourcing electricity through solar cells. Nature has gifted us with sunshine and it does not cost any money to access and use the same. The solar power cells convert the light energy emitted by the sun and turn it into electric power. The power can be directly fed into their electric gadgets or it can be stored in heavy-duty cells (like the ones used in automobiles) and use it as and when required.

Ask any person who has installed such solar cells, especially those who have assembled the same via kits available on the net and in stores that specialize in electric equipment, and they will tell you of the substantial savings they are benefiting. Those who are interested in installing a solar power rig in their home first have to calculate how much power they require from such cells. Once these formalities are over with, they can purchase a kit that will provide them with the requisite power. Installing such a kid is child’s play and a basic knowledge of soldering is more than enough. The kits generally contain of individual solar cell modules, an exhaustive and illustrated setup manual and an aluminum panel to hold the completed solar cell array.

These cells are connected to each other in series and the final output point goes directly into the equipment that needs power or to the battery. These kits are so cheap that they pay off for themselves within a few months post installation. The current generation photovoltaic cells convert about 30% of sunlight that falls on them to electrical energy, but scientists are working to make more efficient photovoltaic cells that will provide more power per exposed meter of solar cells. The prime advantage of using solar cells for a solar energy house is that they hardly require any maintenance. Just dusting the panels once every few days to ensure that sunlight falls on them properly is more than enough.

Home Solar Energy – Easy Steps To A Warm House

Whether building your House or remodelling it, it can be made in to a solar energy house by throwing some simple changes in your plan. If the electricity and gas become costlier then turning to solar energy is not only a cheaper solution but is natural and environmental friendly too, because this alternative form of energy production gives of absolutely zero emissions into the atmosphere by making use of most natural source Sun as its driver.
On reaching it disperses evenly and can be channelized to a particular area like your home. How can you get the required amount of sunlight to heat a home? It?s quite simple and only takes some simple extra measures to get it started.

Steps to building or remodelling your Home

Building your own home can have multiple choices regarding home heating source. Solar heating works much cheaper than electricity. In case your choice is solar heating then your home needs to be east facing i.e. in the direction of the rising sun. Thus your home gets the maximum sunshine during the hot period of the day. Fixing Solar Powered Glass Windows also helps to lock the warmth of sun that comes through in the home during the day without letting it escape thus keeping your home warm even after sunset.

Only condition is that the door should be kept closed in order to lock the heat and install insulated curtaining on the windows at night so that warmth remains in the room through out the night. Also ensure that there are not many windows on West side of the house because setting sun may cause the home to cool down quickly.

In case you wish to use the sun as a natural heating source then it is extremely simple to remodel your house. Even though your home is not facing the rising sun, it is quite easy to shut in the sunlight that comes in by building a sun room on the east side of your home to trap the morning sun light thus heating up the room naturally and then with the help of ceiling fans circulate the air into the other parts of the house.

During the day this will not only keep your warm but reduce the mount of time used on other source of heat. While remodeling the home installing solar power windows specially designed to attract the sunlight, will allow trapping it in without letting it to escape. Thus heating your home naturally.

Using solar energy to heat up your home naturally is not only the best way to reduce your energy bill but is environment friendly to because it gives off absolutely zero emissions. A backup heating arrangement can be installed incase the sunlight is not sufficient to heat effectively due to clouds. Thus reducing your electricity bill considerably.

Home Solar Energy System – Why You Should Consider A Home Solar Energy System

I’m fairly certain that the majority of people would like to be free from the costly grip of the power company, and in turn be able to reduce their monthly bills. The problem is that most of us don’t know how to do this. But what if there was a step-by-step guide that could demonstrate exactly how to build your own cost-efficient, home solar energy system? Would you want to check it out? I’m assuming the answer is yes, so I will continue on.

The reality is that having a solar energy system installed in your home can be very expensive, to the tune of around $20,000. That said, the only way to do this cost-effectively is to build your own. On the surface, this might sound like an arduous undertaking, but luckily, many people that have gone before us and paved this path already. There are several, simple to follow DIY tutorials that you can take advantage of.

With today’s increasing awareness of global warming caused by the excessive burning of fossil fuels, more and more people are looking to reduce their “carbon footprint” and take more responsibility for the care of the Earth. If you want to be a part of today’s green revolution, then home solar power is a great option. It’s renewable, clean and doesn’t really require much upkeep after the initial installation. Installing your own system is not only great for the environment, but it will also provide you with a great back-up source of power in the case of outages in your area, and additionally save you money at the same time. Solar energy itself is free and endless. There is no reason why we shouldn’t take advantage of it in our own lives.

Solar Energy for the Home

?

Solar energy for the home can be a great way for you to reduce your reliance on the energy companies and oil prices. As well as decreasing your reliance on fossil fuels you will also be lowering your carbon foot print and making your own contribution to global warming smaller.

?

The only real draw back of using solar energy for the home is that it has a high initial cost to get up and running. There are many state and federal programs that can ease this a bit though, such as grants, tax breaks, and government loans. While the initial investment is high the system will pay for itself eventually by reducing or completely eliminating your current power bill.

?

Solar energy systems also require very little maintenance because there are no moving parts. A solar panel will usually just continue to put out power until something actually damages it. There is some power loss from the panel as it ages but this is a very small amount.

?

A large part of the install can be done by yourself if you are handy around the house but you will need a professional for parts of it, like connecting your system to the grid. There may also be certain items that will require a professional depending on the building codes for your local area.

?

The very basics of the system are the panels, the inverter, the interlock, and the monitoring equipment.

?

When the sunlight shines on a solar panel then there are electrons freed up in the panel. The electrons start to move and produce direct current electricity. The panel itself is made up of individual solar cells. Each of these cells will produce about a half of a volt, so if you have a 24V panel then there are going to be 48 individual cells in it. The actual current or amperage that the panel is capable of is determined by the size of the solar cells in the panel. The larger the cells then the more current your panel will be capable of producing.

?

The next components are the inverter and the interlock. The actual operation of an inverter is fairly complex but what it does is fairly simple. It takes the DC power generated from the panels and converts it to AC so that it will be compatible with the appliances and lighting currently used in our houses.

?

The interlock is basically the switch that ties your system to the grid. This helps determine where your power is coming from at a given time, from the power company or from your solar energy system. It should also contain some safeties that will prevent your system from feeding power back in to the utility companies lines in case of a blackout. Feeding this power back in could be very dangerous for any electricians that are working on those lines during a power outage.

?

The monitoring equipment of course does just that. It follows the status of your system and some of the more complex units can keep track of how much power you are generating and how much you are using.

The History Of Solar Energy

Throughout man’s history the sun has always been a subject of speculation and worship. In fact, most ancient cultures have deified the sun, due to its life-giving and energy-giving qualities.

Thus, the subject of solar energy is one of the oldest subjects on Earth. It has gone through many evolutions and has been the subject of many schools of thought – starting with religion, and ending up in the field of science.

In fact, though not many people know this, a large portion of the western civilization celebrates the returning of the sun each year, just as the ancients did thousands of years ago.

I am, of course, referring to Christmas – which dates back to the celebrating of the winter solstice, the point in time when the Earth has reached its furthest point away from the sun, and starts returning.

Of course, the story of Christmas has radically changed from its original meaning. It has gone through its own evolution. Originally being a celebration of the sun’s return, it then became the celebration of the birth of Christ, and eventually wound up with a friendly old man bringing Coca Cola on Christmas Eve. But this last point is simply modern marketing at work.

The First Uses of Solar Energy

It is almost impossible to exactly date the first uses of solar energy.

But we do know that the ancient Greek and Roman civilizations, among others, made use of “passive solar energy” in their building designs.

Passive solar energy is the use of a building’s architecture to capture the sun’s heat and light.

In 200 B.C., the Greek scientist, Archimedes, used concentrated solar power technology, (now referred to as “CSP”) by combining the reflective properties of many polished bronze shields, in order to focus sunlight and thus set fire to an invading Roman fleet while it was besieging Syracuse.

(In 1973, The Greek Navy recreated this scenario as an experiment, and succeeded in setting fire to a wooden boat 50 meters away.)

Socrates and the Romans

Even the famous Greek philosopher Socrates has commented on the benefits of facing one’s house toward the south, in order to make use of the heat provided by the sun in the winter.

The Romans also used this technique, of facing their houses southward, but they took it a step further. They also installed more windows on the south side, allowing the heat and light of the sun to freely enter the buildings.

Throughout the first four centuries after Christ, Roman bath houses employed passive solar heating. The Romans built the bath houses with large, south-facing windows, to let the sun’s warmth in. This aspect of passive solar technology is still used by architects today.

With these methods, they were able to reduce the amount of fuel they needed to heat their buildings. And considering that you had to go out and chop your own wood in those days, it was well worth it.
