Types of Solar Panels

What are the different types  of Solar Panels are there? 

If  you have ascertained what size solar panel system  you want , the next step is to judge what kind of solar system  will meet your household requirements  . This should not be a decision based purely  on budget  , because solar panel efficiency  , longevity,warranty , and space needed are all important factors. Too often customers base there purchasing decisions on price only and wonder why no-one picks up the phone from the “fly by night company” you purchased  your solar panels from when in  3 years your inverter dies or your output is halved or significantly reduced . But its also important to  understand  that there are different qualities of solar power brisbane systems  on the market and you should compare “apples with apples”, not apples with oranges. So although there are 3 main types of panels ; Mono crystalline, Polycrystalline, and thin-film or Amorphous  its important to recognize the advantages and disadvantages of all of them  . If your main hurdle for purchasing panels is price, then I suggest you compare “like with like” so its silly to compare the price of Mono with the latest Amorphous panel and make your  buying  decision based from price alone.

One of the most important distinctions to make regarding Solar panels is the different Watts available. Watts are related to the output of the  panel, so a 200W solar panel would output 200 watts per hour. Expect to pay double the price of a 100W panel .

Warranties

Solar power panels come with a  performance warranty as standard  that may last up to 25 years and a guarantee of five to ten years. As well,  solar power companies  can provide a warranty on workmanship , typically five years.  So why not ask your solar power company  who is providing the warranty–the importer or the manufacturer–and what happens if something breaks or malfunctions .

There are three  different  types of  solar panel systems  available, each with their own benefits.

Mono crystalline cells 

Mono crystalline  solar panels  are proven and reliable technology, used over the past 50 years and  is still common in every day solar power applications . They have the  highest  conversion efficiency, at 12-18% of all sunlight. Because these have the highest power to size ratio, they’re  one of the best  options  if you’ve got limited roof space. They also degrade very slowly, generally losing 0.25 – 0.5% per year. Their lifespan can be 25 years, even up to 50 years if they panels are being taken care of and maintained and cleaned on a regular basis  .
Disadvantages: Mono crystalline cells don’t perform as well as other  solar panels  in shady conditions and they are quite fragile. They are more expensive to manufacture because of their complexity.

Polycrystalline cells

Polycrystalline compares well in performance and longevity to mono crystalline, and provide efficiency of 12-13%. Well known brands include BP SX, Sharp and Kyocera .
Both crystalline panels have great longevity (around 25 years). Both work optimally at 25oC and will lose some efficiency at higher temperatures (over 50oC) – common in our summer .

Amorphous Thin Film

Thin film panels  mostly  have a much lower efficiency at 6%, however,Cadmium Telluride Thin-Film panels (CdTe) have progressed to 11% efficiency. These are more suitable for inland Australia conditions where space is no problem  and temperatures are hot . Amorphous panels do not lose energy in higher heats.
Disadvantages are: expected lifespan is less, there is a 3-6 month  running in or warming up  period, and they typically require 2-3 times the  roof area  for the same output of crystalline cells.
When choosing, remember to focus on the goal of recouping your initial costs through savings in electricity . The more efficient and higher Watt panels will do this faster .  However, if you are looking at solar farms in Outback Australia where temperatures routinely get above 40 degrees Celsius and there is a bit of cloud cover as these panels work much better in the shade also then these panels  would be well suited to you .

Just What Are The Accompanying Solar Home Costs For Unit installation?

Human beings have constantly tried to find various methods to harness the energy around them for their own use. As the years pass, human beings have discovered an increasing number of varied methods in which they can harness and use energy to sustain their demands. In this search, human beings have discovered that they are able to develop a source of power in the kind of electricity. This source is among the most common providers of energy to the homes, offices and sundry other areas exactly where individuals congregate. However, the use of electricity comes with a price tag. Electricity bills have been the source of worries for some and are deemed money consuming item.

In the search for a a lot more inexpensive and environment friendly supply of energy, man has turned to the sun for an answer. Harnessing the sun’s energy has been productive and now, techniques and means have been identified in order that the harnessed energy of the sun may be employed in houses. By being able to use the sun’s energy inside the houses, solar home cost from the electricity bills may be trimmed in half or entirely discarded. The promise of the last alternative, that’s total absence of any electrical energy bills, has ensured that people’s interest in solar energy continues.

Authorities are of the opinion that solar home cost less in the long run than electrical energy powered homes. This is because of the fact that by becoming solar energy based, homes will no longer be dependent on electricity, and can therefore become power independent. After all, the hassles of being electricity based is really familiar taking into consideration that electricity powered properties are liable to suffer the identical fate of their neighbors that are dependent on the electrical energy grid in their area. No electricity means the absence of energy of any kind for them. On the other hand, solar energy based properties can continue to experience energy in the homes in spite of the lack of electricity.

Solar home cost is largely dependent on the kind of home a person has or is planning to build. Bigger homes call for bigger power consumption. Hence, there is going to be a need to install more solar panels as well as other equipment for the capture of solar energy and turning the identical into power for the use of the different appliances that man needs to survive. Expense can also vary depending upon the type of machine one decides to use to convert the sun’s energy.

Overall, the creating of a solar home can be deemed high-priced at the start. Even so, such an expense is only at the beginning considering that these costs are connected with all the building of the house and furnishing the identical with the necessary equipment for the conversion of the sun’s rays into solar energy. After the initial expense, the homeowner can begin harvesting the fruits of his labor considering that he will no longer need to worry about his electrical energy bills. Much more importantly, the homeowner becomes power independent with the added bonus of becoming environment friendly.

My Alternative Energy Sources (Solar Energy)

Exactly what is an Alternative Energy Source? Well in other words, an Alternative Energy Source provides energy that is sustainable and does not utilize fossil type energy sources that produce pollinates back into our atmosphere. It is likewise thought about as a fuel source or energy source that is totally free. Examples of sources of energy that are not free are oil, coal, natural gas etc.

These energy sources are often refereed to as Fossil Fuels indicating that they have been formed in the Earth’s ground system over countless years. These energy sources are not sustainable (because it takes millions of years for them to form), they are expensive to utilize and they produce damaging emissions during there use. In recent years the United States as well as other nations around the world have started utilizing Nuclear Power to generate electricity, however is this approach actually any safer or more cost effective than other approaches? Exactly what do we made with the plutonium rods that are used up in a reactor? These plutonium rods discharge hazardous radiation for many years after they are eliminated from a reactors core and need to be saved in under ground caverns permanently to keep from being hazardous to society.

So what is a real Alternative Energy Source? A real source of alternative energy is the following:

Solar Power
Wind Power
Magnetic Power

These forms of energy are complimentary, they are eco-friendly and they are abundant. Let’s take a look at every one of these in more detail.

Solar Energy:

Just exactly what is Solar Energy anyway? Solar Energy is energy that is produced by sunshine more, specifically radiant light waves. These light waves produce heat and light and are taken in by the Earths land surface area and water surface area. About 30% of this is shown back into the environment. Have you ever stood beside a glass window on a bright sunny day and felt the heat that is radiated by the glass? This is a kind of Solar Energy, the glass absorbs and gathers the heat from the sunlight although not very effective, the glass is a collector for this heat. Technology today has developed methods of collecting this Energy that allow us to use it in our Homes and Business as:

Solar Heating
Solar Water Heating
Solar Electricity

How do we do this? By what is referred to as Solar Collector Panels. These panels are made from a material that takes in the energy from the sunshine and transfers it either as heat that we can utilize to heat our homes, heat water for warm water or with making use of storage cells as electricity for our houses. As the majority of us experience sunshine for 8-12 hours each day (when it is not cloudy) this is an exceptional source of an Alternative Energy Source.

These solar panels are placed on your house (normally the roofing) to gather the most sunshine offered during the majority of daylight hours. This is called Direct Solar Energy as we are catching the sunshine to do instant work, warm your house warm your water or create electrical power. The most frequently made use of method of producing solar power is through solar batteries or solar panels. Photovoltaics, or solar cells as they are often called, are made from a material called silicon. Following a chemical process, the solar batteries are produced and can then turn the photons from the sunlight into energy.

The type of energy generated by means of a photovoltaic cell or cells can be saved in batteries and after that used to power everything from radios, calculators, toys, solar lights, battery chargers, solar roof vent fans, water fountains, solar powered water pumps and generators and more!

Benefits of Solar Energy

Solar energy itself is totally free
Pollution-free way of providing power
Renewable resource source
Operates quietly
Solar energy cells or panels are almost maintenance free and will last a very long time
Easy setup
Conserves cash in time on electricity costs

Solar power is being used around the home for numerous requirements, such as cooking, water heaters, drying clothes. We even currently have actually solar energy lorries on the roads today.

The prospects of solar energy in the future for big industries is extremely possible also, since these industries require so much energy and power they are using coal to assist meet their energy requires. In the future I can ensure you that eventually all present energy grids will be changed by solar energy systems.

Space and Solar Energy

A space shuttle needs massive quantities of fuel to function. Here too is another area where in the future the energy from the sun will totally control this sector.

Transportation and Solar

As we all know oil will one day be worn out, transportation in the future will also be dominated by solar devices. As I discussed earlier there already are solar powered lorries on the roads, actually they are even here where I reside on an island in the pacific.

By the year 2020, experts say planetary systems will be used, opening numerous possibilities for solar energy in the future. People are now realizing the significance of going solar and starting to check out utilizing this energy. We are becoming more knowledgeable about the possibility that our other resources will one day run out. So the quicker we can start utilizing solar the better.

Pollution Control

A great element about solar power is its clean, unlike other sources of energy. The contamination rate is currently rather troubling. This lovely world all of us live on is gradually being destroyed, if we could all think about utilizing solar or wind energy then we could definitely make a distinction in our health and the future of our world.

We can start by doing some research about solar panels and their building. Photovoltaic panel truly are an extremely easy technique of producing energy, and can quickly be installed. There are many individuals today constructing their own photovoltaic panels, with the best directions and materials there is no reason anyone could not do this. At the end of the day, our future will be dedicated to sustainable sources of energy and your finest possible choice is solar energy.

The Benefits of Residential Solar Panels

Are You Considering Residential Solar Panels For Your House?

Residential solar panels are an excellent investment that not just conserve you loan and can increase the value of your home or business, but they likewise assist the environment. Solar power is becoming very price competitive with standard energy sources and there are many federal and state refunds and rewards in place to compensate you for the power you produce as well as assist offset your initial financial investment expense. The expense of property solar panels for your house have decreased substantially, dropping over 40% in simply the last few years. There has never been a better time to make the transfer to renewable tidy energy for your home or business.

The Basics of Residential Panels

Residential panels convert the sun’s light energy into electrical energy using a selections of solar batteries to convert photons into usable electrical energy. Solar cells, or photovoltaic cells, are set up in a grid-like pattern on the surface of the panel to produce a particular wattage of electrical power. Then several panels are organized in a variety and installed on a roofing or in a field, which produce energy that can power a house or organisation.

Residential panels usually are built with crystalline silicon and the more expensive gallium arsenide, which is produced exclusively for usage in photovoltaic cells. More effective panels are put together by transferring amorphous silicon alloy in a constant roll-to-roll procedure. Cells created from this process are called Amorphous Silicon Cells, or A-si. Panels constructed using amorphous silicon technology are more resilient, effective, and thinner than their crystalline counterparts.

The latest panels operate on the molecular or quantum level. These panels are developed by implanting carbon nanotubes or quantum dots into a dealt with plastic. Unlike silicon-based panels, these panels do not need to be built in a clean room, and for that reason production costs are rather lower.

Residential panels work by gathering radiation from the sun and actively converting that energy into electrical power. Solar panels are comprised of several individual solar cells. These cells operate likewise to large semiconductors and use a large-area p-n junction diode. When the cells are exposed to sunshine, the p-n junction diodes transform the energy from sunshine into functional electrical energy. The energy created from photons striking the surface of the solar panel enables electrons to be knocked out of their orbits and released, and electric fields in the cells pull these totally free electrons in a directional current, from which metal contacts in the cell can generate electrical power. The more cells in a solar panel and the greater the quality of the cells, the more overall electrical output the solar panel can produce.

How Much Power Can Be Produced?

The quantity of energy that is produced by solar panels is affected by the quality of the panel, the materials and innovation that are used in making the panel, and the amount of time the panel has been in use. When purchasing solar panels, it is best to look beyond the size of the panels and to take a look at the dollars/watt ratio.

Residential solar panels of the same size may produce variable quantities of electrical power, this disparity is caused from variations in the working age of the solar batteries, the quality of the solar cells, and with exactly what technology was utilized to produce them. Early cells are not as effective as modern-day cells. Panels have a reliable lifespan of about 20 to 25 years, and their worth and wattage output reduction gradually gradually.

Get More Out Of Your Residential Panels

The best way to get the most out of your residential solar panels is to take easy actions like switching to CFL or LED light bulbs, buy energy star home appliances, utilize clever power strips that shut off electronics when not in use, and making certain your windows, doors, and insulation are energy effective.

Impacts of Clouds on a Solar Panel

Solar panels hold a wealth of benefits, both for individuals and for the world at large. Economically, solar panels guarantee to reduce the expense of electrical power. Environmentally, solar panels can provide us cleaner power, sustainable power that will not need more damage to the environment. Solar power can reach remote areas. It can bring education, or urgently needed medical information.

The results of clouds on a solar panel, though, may reduce those and other appealing advantages.

The impacts of clouds on a solar panel may make it far less efficient in specific parts of the world and at specific seasons.

For that reason, people who are considering solar panels for their homes are typically heard to ask: will clouds impact my solar panels?

Will Clouds Affect My Solar Panels?

Clouds do impact solar panels. The amount of power your solar panels can produce is directly based on the level of light they get.

Completely, bright sunshine, solar panels receive maximum levels of light. During those “peak” sunlight hours, your solar panels will produce power at their optimum capacity.

When clouds cover the sun, light levels are reduced. This does not closed down power production, nevertheless. If there suffices light to cast a shadow, in spite of the clouds, your solar panels must run at about half of their full capacity. Thicker cloud cover will reduce operations even more. Ultimately, with heavy cloud cover, solar panels will produce very little useful power.

The Good News!

The results of clouds on a solar panel can be surprising excellent, nevertheless. Extremely, your solar panels will put out their ultimate quantity of peak power during cloudy weather condition!

As the sun moves into a hole in between the clouds, your solar panels will see something wonderful. They will see full direct sunlight “plus” reflected light from the clouds! They will drink in more energy than they could on a cloudless day!

The impacts of clouds on a solar panel might then produce peaks at or above 50 percent more than its direct-sun output!

Meeting the Challenge

There are methods to satisfy the cloud difficulty.

1. If you often have clouds in the afternoon, but early mornings are clear, intend your solar panels slightly towards the east.

2. Be sure you utilize a big sufficient battery system to maximize the quantity of power kept for usage when the clouds show up.

3. Ensure your controller has a lot of headroom over the ranked panel output power so that it can take in the rises when the sun reflects off the clouds.

Those techniques and more are practiced in cloudy areas of the world where people have run far ahead of the United States in their use of solar panel energy.

Effects of Clouds on a Solar Panel in Germany

Germany is normally a very cloudy country. Read about the climate of Germany, and you will find that it is “temperate and marine; cool, cloudy, wet winter seasons and summer seasons; periodic warm mountain (foehn) wind” according to Nation Master’s website.

In spite of its cloudy climate, however, Germany is by far the world’s most significant user of solar panels. If you resided in Germany, you could offer back to the primary power grid all of the excess electrical energy produced by your solar panels. Why would I even care in such a cloudy climate? If clouds impact my solar panels excessive, I would not fret about offering back to the main grid.

In 2006, Germany opened the largest solar park on the planet. Germany likewise has Europe’s the majority of contemporary solar housing project – a solar village of 50 solar houses that produce more energy than they utilize!

Will clouds impact my solar panels? Even if I lived in Germany, the impact would not be enough to bypass solar energy.

Suggestion: There are few places that are so regularly cloudy that solar power is out of the question. Improvements are being made constantly, as well as solar panels small enough to fold into a brief-case can produce handy quantities of power.

Seven Steps to Install Solar Panels on Your Roof

Solar panel systems have a bright future in the roofing industry and for home and structure owners alike. Solar panels, likewise referred to as solar photovoltaic panels are exceptional tools for decreasing regular monthly electrical costs, supplying tidy power, lowering dependence on standard nonrenewable fuel sources, and including worth to a home or structure. Installing roof solar panels is one of the best methods to increase the worth of a house or building. And, not to mention that federal legislation extended a 30% tax credit for business and domestic solar panel installations.

The following “7 Steps to Installing Solar Panels” can be used to guide both business and domestic customers through the solar panel shopping and installation process, and help make it as smooth and easy as possible.

1. Make your home more energy effective.

Before you begin the solar setup process you first need to analyze the energy performance of your house. Adding solar photovoltaic panels to a home with bad energy performance is not going to provide the outcomes you expected. In some states to be applicable for the tax credit your home has to have an energy audit performed before the solar panel system is set up, making your home’s energy performance vital. Here are some suggestions to make your house more energy efficient:

* Upgrade or change windows

* Well insulate walls and attic

* Replace ineffective warm water heating systems and/or furnaces

* Replace incandescent light bulbs with compact fluorescent bulbs

2. Examine the solar site or roofing system.

Ask yourself a few concerns: Is the roof strong enough to support the panels? Is the offered area big enough to hold the panels? Does the roofing system offer southern direct exposure? And most important, does your roofing system get enough sun light? Solar panels are suggested to get full sun direct exposure in between 9am and 3pm in order for them to be the most effective.

3. Get competitive quotes.

Solar panels are a huge financial investment, however done properly they can provide a considerable return and increase the worth of a building or house. Look around a little and find the best rate. However understand; don’t just try to find the most inexpensive cost. Discover a well recognized merchant and installer with a strong track record. Educate yourself and ask the ideal questions, because often a greater costing solar system might be the much better choice, and in the long run offer a greater return on your financial investment.

4. Research the cost.

Solar photovoltaic panels differ in expense, which is usually figured out by the size measured in Watts, the real measurements, the brand name, the longevity, the service warranty, and any certifications the solar panel may have. As solar systems increase in size so does the price. Anticipate to pay approximately double for a planetary system of double the watts.

It is probably a good idea to receive several quotes, and if there are big distinctions ask why. And, as discussed before, don’t pick your solar panels based exclusively on cost; make sure it will supply sufficient energy to fit your needs.

5. Determine the needed size and Watts.

To begin, study your electrical energy bill. It will provide you with a great deal of helpful information to approximate your energy requires. Learn how many kilowatt hours (kWh) you use each day, month and year. When sunlight is optimal, a 100 Watt panel will create 100 Watts of electrical energy per hour. The majority of houses electricity needs can be satisfied with a solar system in between 1 to 5 kilowatts or 1,000-5,000 Watts. And in general, 1 square foot of solar photovoltaic panels in brilliant sunlight yields 10 Watts, but that can differ depending upon the type. Ultimately, when identifying the needed size of solar panels be sure that they will provide adequate electrical energy to meet or surpass your requirements.

6. Pick the Solar Panel Type.

There are 3 primary kinds of solar photovoltaic panels that are available to choose from and differ in effectiveness.

* Mono-crystalline panels are essentially one big solar cell. They are smaller sized than the polycrystalline panels.

* Poly-crystalline panels are comprised of numerous little cells grouped together which produce a little less efficiency than the mono-crystalline panels, and are potentially readily available for a lower cost.

* Amorphous (or thin-film) panels are bigger in size and need more area than the other panels. However, there are other significant benefits, such as a lower cost, versatility, flexibility and greater performances in the Midwest.

It ought to be noted that effectiveness just deals with the quantity of light that is created on brilliant sunny days. The thin film panels have the distinct capability to produce watts in low light and overcast conditions, therefore increasing its yield of watts over the exact same time for the other panels in less than optimum climates like the Midwest. Side by side contrasts in the desert expose something, however side by side comparison in a location that only has 4.2 hours of sunlight on average daily, the thin movie provides an unique benefit.

One need to also think about that the structure needed to mount the panel type vs. the thin film can include expense and future upkeep.

As there are different types of solar photovoltaic panel roofing systems available, there are likewise various types of installation techniques, such as a grid-tied system, which offers the capability to have more solar photovoltaic panels included at a later date.

7. Review the quote and planetary system specifications.

Read the fine print and be clear on all elements of the new solar panel system. Here specify points to review:

* Total Cost – Labor, setup and equipment.

* Projected cost savings – how many years will it take to pay itself off?

* Operational and upkeep costs

* Required permit costs, if any

* Solar system make and model – is it a trustworthy brand?

* Taxes

* Tax credits – 30% federal tax credit with no cap.

* Utility refunds

* Warranty – how many years? A lot of credible brand names will use a 25 year guarantee. If less, ask the length of time it takes to pay itself off.

Solar Panels stay a great option to reduce your energy costs, in addition to reduce your carbon footprint on the environment. Innovative solar panel style and technology is rapidly hitting the marketplace, so the future is intense for the solar panel industry.

Learn How to Save Money with Commercial Solar Hot Water Systems

Learn How to Save Money with Commercial Solar Hot Water Systems

Commercial solar hot water is not new. Large and small companies, hotels and resorts have been using it to save money for years now.

Not until recently have Commercial Plumbing Contractors pursued the solar how water niche. The demand use to be low but today we are now finding more and more licensed plumbing contractors being asked to contribute their knowledge and expertise in the solar hot water area. Whether it is a system for a new commercial project/facility or an eco-friendly addition, commercial plumbers are being asked to design/build systems for facilities from simple neighborhood laundry mats, public swimming pools to some of the largest name hotels, resorts and institutions. All businesses are looking to cut costs in their fuel energy costs and solar hot water is turning out to be a ‘hot’ and money saving solution.

All you really need today for effective solar hot water heating are two things: you need solar panels and you need a hot water storage tank. Solar panels are made from evacuated tube collectors that simply collect the solar energy from the sun, transfer this heat to the water and then into the copper coil heat exchanger located inside the hot water storage tank and from there it moves on to the domestic hot water system. This is one of the most efficient ways to use the energy of the sun for hot water uses.

The second component for solar hot water is the storage hot water tank. A storage tank can be designed and built for any type or size of project, regardless if it is for a new building or a pre-existing building. So long as you have a place that is flat, level and can support the weight of the water in the tank. Getting very large water storage tanks into existing buildings use to be a major problem but today we use a specially designed storage tank that comes in a collapsible form and can fit through a 19 inch door way and be set up in a matter of hours. This tank is state of the art and a one of a kind. This unique collapsible design is what makes it ideal for pre-exisitng buildings.

Major Types of Solar Power Systems

Major Types of Solar Power Systems

Solar Direct (or Day-Use Solar)
These systems do not have any storage batteries and are intended to be used only when the sun shines.
Without storage batteries, the power stops as soon as the sun goes away.soon as the sun goes away.
These systems are best suited for certain water pumping applications, venting fans, and certain electronics. Rare in application, they are very affordable and easy to install.

DC System with Batteries
These systems are great for small electronics that need to run day or night. Often times you’ll see these systems employed on highway sign lights, gate openers, and communication boxes. Simple and
affordable these systems have a wide variety of uses and are perfect for remote locations that require low voltage.

Hybrid Solar-Generator Systems
Most folks turn to a hybrid system for off-grid and back-up power applications. The hybrid system
generally consists of a PV array, a charge controller, a battery bank, an inverter, and sometimes a tertiary power source such as a wind turbine or a gas generator. This type of system is fairly complex and will require a high level of expertise to design and install. With the popularity of off-grid living, however, there are more and more packaged systems for people to choose from. These systems will provide power if the grid shuts down and can still sell power back to a grid if desired.
