How to Get Energy Using Photovoltaic Panels

!±8± How to Get Energy Using Photovoltaic Panels

What should I understand before buying a photovoltaic system?

The first step in energy home improvement is energy saving. This does not mean going back to the Stone Age, or become an environmental extremist, but simply take small consistent steps to consume less.

Once you understand how much you spend in electricity with your devices, You can understand how to save and what type of system to buy.

What is the productivity of a photovoltaic system for the production of electricity?

The Sun also can give 100% of the electricity needed to our home. Unfortunately solar photovoltaic installations have a much lower yield of solar thermal systems, which are used to heat water, and therefore we must cover an area greater than the roof.

Unfortunately the solar photovoltaic costs much, and not always we can allow a facility sufficient to cover our annual requirements of electric current.

How much savings annually?

Practically every one of us can decide how much to save electricity, simply by buying a plant more or less powerful, according to an annual consumption of how many KWh We consume every year.

A house of 4 people with low light bulbs use, no air conditioners, heating and gas cookers, the normal consumption is around 1500 -2500 Kwh a year.

While in a house of 4 people, where there are no such conditions above, the annual consumption is around 3.000-4.000 KWh.

How much spent on solar photovoltaic installation and maintenance?

The photovoltaic systems are usually sold under KWh in producing ideal conditions for irradiation.

An installation base is 1,200 Wp (means that under optimal conditions produces 1200 watts peak) and produces about 1,300 / 1,500 KWh per year (cloudy climate), while 1.600-2.000 KWh per year (sunny climate). It costs nearly 5.000 US Dollars 6,500.

While a 2,000 Wp plant costs about 8.000 US Dollars (installation and transportation included).

However the cost of the facility may deduct the tax recovery see the new tax credit approved by the congress in 2008.

These types of solar systems do not require special maintenance, wishing you can clean the various photovoltaic panels every 2-3 years, although usually the same remain fairly clean by rain and wind.

The person who wants a DIY Solar project should be interested in flexible solar panels. This is a product review of one type of flexible solar panel. These are perfect for the person who has some knowledge of renewable power and has a plan.

These panels have the following features:

* Virtually unbreakable due to no glass

* Encapsulated in UV-stabilized polymers, includes EVA and the fluoropolymer ETFE

* Easy peel & stick application with microbial inhibitor

* Bypass diodes are connected across each cell

* Shadow & high heat tolerant

* High temperature and low light performance

* Quick-connect terminals

They come in a variety of watts and they have different physical dimensions. For example, the 124 Watt panels is Length: 5486 mm (216")x Width: 394 mm (15.5")x Depth: 4 mm (0.2"), 16 mm (0.6") including potted terminal housing assembly Actual Weight: 17 lbs.

These flexible solar panels are designed to work in high temperature and low light yet still deliver on energy. They have quick-connect terminals and adhesive backing with bypass Diodes for shadow tolerance. The adhesive is an Ethylene propylene copolymer adhesive sealant with microbial inhibitor. As you can see below under application criteria, these products have been approved for substrates that include certain membrane and metal roofing products.

The Performance Characteristics:

Rated Power (Pmax): 68 Wp Production Pmax Tolerance: ± 5 % Construction Characteristics 16 mm (0.6") including potted terminal housing assembly Output Cables: 4 mm2 (12 AWG) cable with weatherproof DC-rated quick-connect terminals 560 mm (22") length Bypass Diodes: Connected across every solar cell Encapsulation: Durable ETFE high light-transmissive polymer Adhesive: Ethylene propylene copolymer adhesive sealant with microbial inhibitor Cell Type: 11 triple junction amorphous silicon solar cells 356 mm x 239 mm (14" x 9.4") connected in series Laminate Standard Configuration Photovoltaic laminate with potted terminal housing assembly with output cables and quick-connect terminals on top.

Application Criteria

Installation temperature between 10 °C - 40 °C (50 °F - 100 °F) Maximum roof temperature 85 °C (185 °F) Minimum slope: 3° (1/2:12) Maximum slope 60° (21:12) Approved substrates include certain membrane and metal roofing products

Flexible solar panels work on the same principles as a framed photovoltaic cell. A special manufacturing process that is called "thin film deposition" makes them flexible. These panels are a layer of silicon applied to a thin film panel that is only micrometers thick. This way, when it is applied to a roof or similar substrate the silicon will flex or bend.

One advantage to this manufacturing process is it creates rolls of solar panels. The manufacture can then cut these into smaller pieces for sale as panels. The customer can buy what they need based on the power output desired. It allows suppliers to sell these panels in a variety of diy solar kits. It is also easier to install these panels since you can just roll them out, hook them together and hook them into batteries for storage or an output source.

Thin film flexible solar panels are lighter than mono-crystalline and poly-crystalline solar panels. That makes them better for installing on roofs and it makes them ideal for portable solar applications. Many portable solar battery chargers use flexible solar panels.

These flexible panels are a great way to build that diy solar project you have in mind. There are plenty of places today to get plans for putting solar panels on your roof or even make a smaller project for a solar water heater or solar swimming pool heater.

Best Solar Panels - Basic Info and International Survey Results

!±8± Best Solar Panels - Basic Info and International Survey Results

If you want to plan for the purchase of a complete solar system, or if you are shopping for parts to assemble the solar panels will ensure that the best equipment to purchase for your individual purposes. This article provides some basic information about solar panels, so that the right decision.

One very beginning, there is nothing like "the world's best solar cells for all." It makes a big difference if you want to generate electricityfor your home and also the excess power capacity in the electricity grid, or if you have a car battery from time to calculate. And the hot water from a solar system actually needs a totally different technique. In a strict sense, the so-called "solar thermal" or "collectors" are not even correct the solar panels. So what's the difference?

Solar panels (photovoltaic modules, photovoltaic modules) to convert short-wave radiation, as part of sunlight into electricity.They consist of connected solar cells that are protected by a number of different materials. The surface is transparent and the solar panel is framed in a frame made of mostly aluminum.

Solar collectors on the other hand, a system of tubes filled with liquid. Sunlight heats the tubes and the liquid. A heat exchanger transfers the heat is now on the circuit water system for hot water and heating. As mentioned in this article "the best solar panels," back from the generation of electricitysunlight and solar panels will save for another article.

Before you buy solar panels to look closely at the data sheet of the solar panel. It gives you important details of each solar module and helps in the selection of the best solar panels for your purposes. Maybe you want primarily to the following data:

Solar cells per se - what type of semiconductor material is used?

- Mono-crystalline silicon cells (c-Si) have an efficiency ofmore than 20%
- Polycrystalline silicon cells (mc-Si) have an efficiency of 16%
- Flat-film cells of amorphous silicon (a-Si) have a yield of 5% - 7% (better sales of solar panels
thetime)
- Micro-crystalline silicon cells (mu c-Si) are combined with silicon cells up to 10%
- Gallium-arsenic-cells (GaAs) cells of cadmium telluride (CdTe) cells, and chalcopyrite (CIS, CIGS) have efficiencies of 10 to over 40% (GaAs). Are not (yet) suitable for mostprivate customers, as are either very expensive or not yet fully developed, however.
- Panels with organic solar cells, solar cells may be the best in the future, because they can be produced at relatively low cost. At that time, their efficiency is still low (pigmented Grätzel cells are 10% max. And some are not), and their life expectancy is short (5000 hours). But keep in mind for portable electrical devices.

Solar module conversion efficiency

To see morethe overall efficiency of the solar module, not only of individual solar cells and be aware that high levels of efficiency are nothing without a guaranteed minimum performance. (See next paragraph)

Solar Power Module

Provides information about the performance of each solar module. Look for the (promised) performance standards, because the maximum power in watts (Wp) is specified, always check under test conditions (STC) were measured. As you know, it is naturalLaboratory. It offers real living conditions, and can vary in many ways surprising.

Operating voltage

Open circuit voltage, in volts (V) is specified, the maximum voltage of a solar cell produced by the light and is not connected to a load. To get hotter solar panels, the lower the load voltage is.

Operating Temperature (TOR)

As mentioned previously, the operating voltage decreases with increasing temperature. Make sure that the local climate, the TORConditions.

Construction

Remember you are buying a fragile high-tech product that can be installed on the roof and should be able to roasting sun, wind, hail and snow-load handling. Select the correct system installation. Medium Duty is good, heavy better. The best solar cells are useless when the roof collapsed and blown to the ground.

Size

Compare the size of the active area of ​​the panel to avoid wastingSpace.

Inverter

An inverter converts the solar-electricity (direct current, DC) to alternating current (AC). Enter wrapped with heavy copper transformer's output. Set and forget. Otherwise, we will repair or replace the drive forever - sooner or later. In the worst cases, it is necessary on a regular basis. This is not a joke and a waste of time and money.

Guarantee

20 to 25 years warranty on mono and polycrystalline siliconsolar panels are common. This should be the minimum when purchasing solar panels, since today best solar panels have life expectancies of 30 years and even longer. Take a look at the factory warranty and do not accept only a dealer's warranty.

Now it's up to you to choose the best solar panels for your needs. Take your time to compare different panels, inverters and mounting systems. If you want to purchase a complete solar system and get it installed, contact more than one dealer. Now you can ask them the right questions.

In the following I have listed some manufacturers of solar panels, that made it into the Top 3 of ENF's 2007 brand survey on the world's best solar panels. ENF is a reputable photovoltaic information company located in China and in the U.K.
The survey gives you a good starting point to find the right panel for you. Please keep in mind that 2 years can be a long time in hightech business so do not rely blindly on the results. For actual info check my blog from time to time (see below). Here are the ENF results:
