About Solar Panels

7/16/2010 2:24:44 AM

Solar panels are a crucial part for the expansion of alternative energy resources and by understanding how these panels operate, you can begin to understand why they are such an effective resource to get energy from. Using silicone technology, Solar panels will most certainly expand in the future and become more relied on to power our homes and lives. Function Solar panels operate using crystallized silicone chips that take energy from the sun and convert it to electricity. This electricity process is done by using thin layers of positive and negative powered substances and a piece of metal to conduct the power. The sunlight hits the crystals and splits it up,sending electrons through the P level, off the metal and back into the N level of the solar panel. The protons stay in the P level and when they meet at a connection point, power is given off through the metal piece and goes through wires connected to the solar panels. One panel is pretty small, so several must connected together to form a Photovoltaic Grid. Grids are all different sizes depending on what they are used for. A common solar power set-up for a home could take up half of a roof, while small grids could power street lights or construction signs. Larger grids, encompassing over 30 acres of acres of land, can supply power to multiple areas and feed that power right into a power grid. Types Solar panels are used to create power for different types of things. The most common is electricity, but solar ovens provide heat instead of having to burn something off. Solar Stills are used to separate salt from ocean water to create fresh water that is drinkable. Solar ponds are giant heaters that use the sunlight to heat water for homes and bathing among other things. Another solar panel gaining popularity are the solar cars that do not use gas and work using solar panels on top of the car. Benefits Solar panels are beneficial for the future for many reasons. One of the main reasons is that solar power is renewable energy source because we will never run out of sunlight. Solar power also does not emit any pollution into the air like other forms of energy. Solar panels also do not have to take up extra space in a lot of cases. Like individual systems, they can easily be installed right on your roof. Significance Solar panels can change the way people live and get their electricity. In fact, if people have a large enough solar panel installed on their home, they can get free electricity and even give out electricity to neighbors for money.With rebates and incentives from local governments, the solar panels will pay themselves off in less than 10 years. Misconceptions While solar panels do need the sun to operate, many people think that they will not have power when the sun is not out. This is not the case though, because solar panels are enabled to be attached to a large battery housing device that can store enough power to support a home's electricity for over a week.

Solar Panel Materials

6/11/2010 11:05:23 PM

At present, crystalline silicon materials (including polysilicon and monocrystalline silicon) is the most important photovoltaic material, and its market share above 90%, and in for a long period of time are still the mainstream solar cell materials. Polysilicon production technology has long been held by the United States, Japan, Germany and other countries 3 7 the hands of the company's 10 factories, blocked the formation of technology, market monopoly status. Polysilicon demand mainly comes from the semiconductor and solar cell. According to the purity requirements are different, and solar energy into electronic grade level. Among them, electronic grade polysilicon for about 55%, 45% of solar grade polysilicon, with the rapid development of photovoltaic industry, demand for polycrystalline silicon solar cells on the growth rate higher than the development of semiconductor polysilicon, polycrystalline silicon solar energy is expected in 2008 The demand will more than electronic grade polysilicon. In 1994 the world production of solar cells is only 69MW, and in 2004 was close to 1200MW, in just 10 years increased 17-fold on. Experts predict that solar PV industry in the first half of the twenty-first century will be over nuclear power as one of the most important basic energy.

Overview of a PV Solar Energy System

3/19/2009 6:32:54 PM

A typical Solar pv electrical system is described to refresh our basic electrical knowledge. This knowledge will allow us to be comfortable with the design of our pv solar system and have confidence that it is not over or under designed. The pv Solar Energy System: A pv Solar system has the four major components. 1) THE SOLAR PANEL: This is the component that receives photons from the sun and converts the photon energy into electricity. The panels are rated in Watts. 2) CHARGE CONTROLLER: This component insures that the storage batteries are not overcharged and damaged. 3) STORAGE BATTERIES: The batteries store our collected electricity until we use the energy to power our appliance. Our electricity is store as the potential energy rated in Volts. 4) INVERTER: This component changes the current from our batteries, which is stored in direct current (DC), to an alternating current (AC) which is compatible with our household appliance. Conversion of Sunlight to Electricity: Photovoltaic energy is the conversion of sunlight into electricity through a photovoltaic (pv) cell, commonly called a solar cell. A photovoltaic cell is a non mechanical device usually made from silicon alloys. Sunlight is composed of photons or particles of solar energy. These photons contain various amounts of energy corresponding to the different wavelengths of the solar spectrum. When photons strike a photovoltaic cell, they may be reflected, pass right through, or be absorbed. Only the absorbed photons provide energy to generate electricity. When enough sunlight (energy) is absorbed by the material (a semiconductor), electrons are dislodged from the material's atoms. Special treatment of the material surface during manufacturing makes the front surface of the cell more receptive to free electrons, so the electrons naturally migrate to the surface. The output of a solar panel is usually stated in watts, and the wattage is determined by multiplying the rated voltage by the rated amperage. The formula for wattage is Volts times Amps equal Watts. So for our example, a 12 volt - 60 watt solar panel measuring about 20 X 44 inches has a rated voltage of 17.1 and 3.5 amps . V X A = W 17.1 volts times 3.5 amps equals 60 watts. Our solar panel rated as 60 watts exposed to 6 hours of peak sun will produce 360 watt hours of power per day. An typical; home will require 4000 watts of DC generating power to produce sufficient kwh to cover annual electrical consumption. This equates to 67 - 20 X 44 inches solar panels from the example above. Wiring the System: Solar panels can be wired in series or parallel to increase voltage or amperage respectively, and they can be wired both in series and in parallel to increase both volts and amps. Series wiring refers connecting a positive terminal of one panel to the negative terminal of an adjacent panel. This connection will produce voltage as the sum of the two panels and the amperage will remain the same as the output panel. Two 12 volt and 3.5 amp panels wired in series will produce 24 volts at 3.5 amps. Solar panels can be wired in parallel by connecting positive terminals to positive terminals and negative terminals to negative terminals. Two 12 volts and 3.5 amps panels wired in parallel will produce 12 volts and 7 amps. A series/parallel wired system refers to doing both to the above. This wiring scheme would produce 24 volts and 7 amps from our two 12 volt and 3.5 amps panels. Inverter: An inverter is a device which changes DC power stored in a battery bank to standard 110 / 240 volts AC. Nearly all our lighting, appliances and motors are designed to use AC power. Inverters come in sine wave and modified sine wave output. Most 11o volts devices can use the modified sine wave output. However, special devices that use lasers or silicon controlled rectifiers will require the pure sine inverter which is more expensive. Auto transfer switching is a common internal feature which enables switching from one AC source to another and / or from utility power to inverter power for designated loads. Battery temperature compensation, internal relays to control loads, automatic remote generator starting and stopping and many other programmable features are available. Charge Controller: A charge controller monitors the battery's state of charge to insure that when the batteries need current when required and also insure that the batteries are not overcharged. Connecting a solar panel to the batteries without a charge controller seriously risks damaging the batteries and potentially causing a safety concern. Charge controllers are rated based on the amount of amperage they can produce from a solar array. If a controller is rated at 20 amps you can connect up to 20 amps of solar panel current output. Advanced charge controllers utilize Pulse-Width-Modulation which insures the most efficient battery charging and extends the life of the batteries. Even more advanced controllers can include Maximum Power Point Tracking which maximizes the amount of current going to the batteries by lowering the panel's output voltage. Many advanced charge controllers offer Low Voltage Disconnect and Battery Temperature Compensation as optional features. The Low Voltage Disconnect allows the terminals to be voltage sensitive. If the battery voltage drops too far the panels are disconnected thus preventing damage to the batteries. The Battery Temperature Compensation adjusts the charge rate based on the temperature of the battery since batteries are sensitive to temperature variations above and below about 75 F degrees. Batteries: The batteries for our system should be Deep Cycle units which are designed to be discharged and then re=charged hundreds or thousands of times. Batteries are rated in Amp Hours (ah) and are usually rated at 20 or 100 hours. Amps hours refer to the amount of current which can be supplied by the battery over the periods of hours. An example would ne a 350 ah battery could supply 17.5 continuous amps over a 20 hour period. Like solar panels, batteries are wired in series and/or parallel to increase voltage to the desired level and increase amp hours.The capacity of the battery amp hour capacity requires careful sizing for the conditions under consideration. Longest periods of no sun or cloudy conditions, availability of generator or grid backup or a standby generator with battery charger are among the conditions for consideration. The size of the battery bank will depend on the storage capacity required, the maximum discharge rate, the maxium charge rate, and the minimum temperature at which the batteries will be used. Overall Design: As with all electrical systems there are voltage losses as the electricity is carried across the wires, batteries and inverters and these losses are dependent on the efficiency of each component. These efficiency losses vary from component to component, and from system and can be as high as 25 percent. A trained technician will be required to fine tune the system for efficiency.

What Is A Solar Charge Controller?

3/19/2009 5:54:05 PM

When you purchase a solar home installation with battery backup, one of the components you will need to select is a solar Charge Controller. What is this object and why is it necessary? 　　Solar panels produce direct current, meaning the electricity from the panels flows in only one direction. They must do, as they cannot produce any other form of current. This current is passed to both the charge controller to top up the batteries and operate household items or to the inverter, to pump electricity into the grid if there is excess. 　　The quality of the charge controller will directly affect the life of the backup batteries. This is due to the particular chemistry involved in the depletion and recharging of the Lead Acid Accumulator batteries. When the battery is depleted of charge, the lead plates inside the battery are corroded. It is this corrosion that provides the electricity. When the battery is recharged, the plates are rebuilt, the opposite of the depleting reaction. 　　Sufficient charge delivered in the right volumes at the right time will allow the terminal plates inside the battery to be restored to as close to their previous condition as possible. This happens through growth of metal crystals on the surface of the plate. If this crystal growth does not happen at the optimum rate to generate large stable crystals, chunks of the metal will drop off the plate and build up at the base of the battery. This is the cause of the slow degeneration of car and other types of lead acid batteries. 　　Lead Acid Accumulator batteries are expensive and also contain a great deal of material and so have a high manufacturing energy. Selecting a good quality charge controller will maximize the life of these batteries in a solar home system. Buying a cheaper controller will result in shorter battery life and a greater long term cost as you will need to replace the batteries sooner than you should. Then, unless you want the same thing to happen, you will also need to replace the charge controller. 　　Purchasing a good quality charge controller will give you peace of mind and greater savings in the long term.
