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.

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.
