Finding Out How Solar Energy Works

Solar panels can help to lower carbon footprints since solar electricity is renewable (green) energy and doesn’t release CO2 or other pollutants. Around 2650 lb of CO2 per year can be saved by a typical home solar energy system, which works out to about 30 tons over its lifetime. According to Tony Juniper (director of Friends of the Earth), the next industrial revolution will be based on these clean green technologies.

Fossil fuel sources are becoming more expensive and providing more difficulty, resulting in more worth being placed on solar energy.. Fears of global warming and growing pollution are resulting in traditional energy sources no longer being seen as a viable option.. With renewable energy sources being limitless, it?s clear a change is necessary from the demand on dwindling fossil fuels. Solar energy will become more affordable as the technology develops and conventional energy costs increase. But many want to know just how solar power works.

Here?s a step-by-step description of how solar power works. When the sun shines on a solar cell, photons (light particles) hit the upper surface. Each light particle then carries its energy down through the cell. They then transfer their energy to electrons in the lower layer. This energy is then used by the electrons, to reach the circuit by jumping the barrier into the upper layer. The action of the electrons flowing around the circuit is what creates the energy we use to run our appliances.

Solar panels are composed of solar cells.. Because the electricity generated by an individual solar cell is not sufficient for most purposes, solar cells are linked to form solar panels. Solar panels are also called Photo Voltaic or PV modules and are produced in various types and sizes; the solar panel most commonly used produces up to 50 Watts and is made from silicon solar cells. For larger quantities of electricity, solar panels may be interconnected.

Solar cells, when joined together, are called solar panels. An individual solar cell is unable to produce enough power to provide sufficient electricity, which is why a few of them are linked together to form solar panels developing more electricity. The most commonly used solar panels (also called Photo Voltaic or PV modules) produce up to 50 Watts of solar electricity and are made from silicon cells. For larger quantities of electricity, solar panels may be interconnected.

Contrary to what many people believe, solar panels do not require continuous sunlight to work; they can still be effective on overcast days. For overnight electricity supply you have two options.You can be linked to the utility grid, in which case when the solar panels are not generating electricity (for example, at night), your supply will automatically come from your regular electricity supplier. If you?re not linked to the grid, after dark your appliances and lights can be run by batteries in which surplus electricity has been stored from your solar panels daytime production.

Solar Energy - It Will Save You Money In The Long Run

Over the years, due to increased awareness and unrest with current conditions, solar energy has garnered more attention. It is being looked at as a supplement, and even a replacement, for the fossil fuels that currently power much of our homes, businesses, and vehicles. One of the factors keeping solar energy from making more headway is its perceived cost versus benefit. There are some things to consider when determining how cost effective it is to switch to solar energy.

The upfront cost is somewhat daunting to those who see only the immediate picture. The benefits of converting to solar energy won?t be instantly apparent. Depending on tax credits and government incentives, a solar system that would adequately power the average home has an initial cost of anywhere from about $2,500 to $82,000. Though that is a rather large range of costs, one must consider that fossil fuels would cost around almost $60,000 over 20 years if average inflation continues at its current rate. Bear in mind, though, that once the solar system is implemented, that?s it. The sun?s rays are free, so consider how large a home is, how much it will cost to power, and compare solar with fossil.

Simply reducing, not necessarily eliminating, the use of fossil (dirty) fuels has its benefits. Some homes don?t have the luxury of being situated in a sunny clime or receive direct sunlight, but a home with supplemented with solar panels will still experience lower electric bills. Businesses and homeowners can therefore create a hybrid system that greatly lowers energy costs. The size of the house and number of household members dictates the amount of energy used, but a solar system supplying only 10% of the total usage will makes its presence felt by reducing the fossil fuel used.

Solar panels themselves have come down in price in recent years. Their cost was one of the obstacles that residential solar energy generation faced, but it is less of a concern these days. Prices currently range from around $9.50 per watt to $11.00 per watt depending on the material from which they are constructed. Flat plate collectors that can daily heat 40 to 80 gallons of water usually run from $2,000 to $4,000.

In terms of home improvement projects, solar energy systems are comparable in price. The amount of energy used in the long run combined with the initial setup cost will determine the cost effectiveness of solar energy. It is an investment for the future.

Basic Photovoltaic Panel Parts

From the operators of www.GreenLivingRocks.com — providing education regarding how to make a home made solar panel, solar hot water heater, and solar energy facts.

One of the reasons that constructing your own pv (photovoltaic panels has become so popular is that there are really very few components involved. A regular solar panel consists of just a few basic parts, namely an enclosure, solar cells, a substrate and wiring. Here?s an overview of what?s involved.

Solar panel container or enclosure
This is what most people see when they think of a solar panel. It?s the clear glass top, the frame and the backing that the photovoltaic cells are mounted on. The case can be large enough to need a custom built metal rack for mounting on a rooftop, or small enough to be a plastic box that can be placed almost invisibly near an outdoor floodlight. It needs to be resistant to ultra violet (UV) rays so that it does not deteriorate with continuous exposure to sunlight. And the glass (usually Plexiglas) needs to be durable enough to withstand harsh weather, including hail and wind storms that could crash tree branches and other debris into it.

Substrate
This is the piece of lumber, peg board or other material that the solar cells are mounted on inside of the enclosure. It too needs to be UV-resistant to survive prolonged exposure to direct sunlight.

Photovoltaic cells
The photovoltaic cells are comparable to the silicon chips that power most computers. They combine the silicon, metals and other materials in a way that captures direct sunlight and converts it into electricity. The electricity can either be instantly used by direct current devices (DC) like LED lights, or stored in DC batteries and converted into alternating current (AC) to power conventional appliances like refrigerators, TVs and other electrical equipment in homes and businesses.

Tabbed and untabbed solar cells
When constructing your own solar panels, you can save money by purchasing untabbed solar cells and soldering the tabs onto the cells yourself. This can be a good option if you have more time than money, but it?s a tedious job. You can save time by buying tabbed solar cells which will cut your soldering time by one-half to two-thirds.

Photovoltaic cell wiring
Once the solar cells are mounted on the substrate, they are wired to each other in a series so that they can produce electricity. Copper wire is added to connect the solar cells to storage batteries for using the electricity later, or to connect directly to the device that the photovoltaic panel is powering like an attic fan or a solar powered toy.

Blocking diode

The blocking diode is a little component that prevents electricity that is stored in a battery from draining backward into the pv (photovoltaic) panel. Bigger photovoltaic systems use a charge controller for the same effect.

What Kinds Of Hot Water Solar Powered Collectors Can You Make Yourself?

From the operators of www.GreenLivingRocks.com — providing education regarding how to make a solar panel, solar panel cost, and solar power generator.

There are 3 main types of hot water solar collectors universally used in homes: flat plate and evacuated tube systems.

How Effective Are Solar Hot Water Systems?

Solar hot water heating systems are relatively simple to install, simple to maintain and the most cost effective way to introduce your home to solar energy. They can save significant energy and cost when they replace an electric hot water heater. And they can be successfully used even if you live in a climate where freezing temperatures are common during the winter.

If you live in a climate that does not have sub-zero temperatures, and your household consists of less than five people, you can put in a batch heater. This is the least expensive solar water heating option, and it is relatively easy to build if you have the inclination to do-it-yourself. It is simply a water storage tank that also serves as the solar collector.

The tank is enclosed in a glass-covered box that is positioned to allow maximum exposure to the sun. The water in the tank heats up and hot water is accessible for use. However, it is not the most efficient system, since it takes longer to heat up an entire tank of water than to heat a flat panel solar collector. Also as the tank cools at night, there is less hot water available for use.

There are two better systems that can be used even in freezing areas. The direct pump system circulates water between a solar collector and a storage container. With this design, water in the solar collector can heat up quicker, and the tank can be insulated for better temperature holding capacity. The pump can be designed to run on electricity from a photovoltaic cell if you want to keep your system completely solar powered.

A thermosiphon system also uses a separate solar collector, along with the pull of gravity. And it allows for the use of an insulated storage reservoir for more consistent hot water delivery. When using either of these systems in cold climates where freezing is an issue, both the piping and the storage tank should be situated indoors and properly insulated to provide hot water even on the coldest days.
