Solar Applications

June 21, 2011 By: Admin Category: Solar Power

Solar Energy Applications

Solar energy technologies use energy from the sun to produce heat, light, hot water, electricity, and even cooling, for homes, commercial and industrial.

There are a variety of technological applications that have been developed to take advantage of solar energy. Technology can be read further below.

Photovoltaics System

Solar cells work by converting sunlight directly into electricity. The electrons in the semiconductor material, the material used to capture sunlight, will move when the sun’s energy in the form of photons hit it. Solar energy is forcing the electrons to move, occur continuously, and consequently there is also a continuous electricity production. Process, which turns sunlight (photons) into electricity (voltage), called the photovoltaic effect.

Solar Cell Module

Solar cells are usually organized into modules that each module can consist of 40 solar cells. Some modules can be arranged to form a PV line fitted with a fixed angle facing south. Or even could be placed in a sun-tracking device, to get more solar energy throughout the day. Several rows of PV could produce enough power for a house. As for industrial applications or power companies, hundreds of lines of PV can be linked to form one large PV systems and sufficient to meet the electricity needs.

Thin Film Solar Cell

Thin film solar cells use several layers of semiconductor material with a thickness in the micrometer scale. Technology allows to create solar cells integrated into rooftops to the skylights. Even solar cells are designed for applications having the same power with actual roof.

Wind Turbines

June 12, 2009 By: Admin Category: Wind Power

Wind Generators As Your Energy Source

Many people have started to install wind turbines, wishing to lower their bills for electricity, and in some way help make the environment safer while saving on non-renewable sources of energy. You need some knowledge before taking your various tools and purchasing your other needs for making a wind generator.

Whether you are installing a self-made or a commercial generator, you need to make sure you have the optimal location for it. You will need a place where trees and buildings are not obstructing the air flow.

If you happen to be living on a farm, obstacles probably aren’t a factor and the view of your neighbors is no concern. However when you live within the boundaries of a city, it can be a lot more difficult to install a wind generator.

The wind towers are so tall that they can be dangerous in storms and high winds, so this could impact the community. Consult not only your local authority but also your neighbors before putting one on your property. Of course you always need to consult for the county or city codes.

You have a few choices for the exact spot for your wind tower. The top of your house could be a great location or if you own enough land you can set the tower away from the house. In a small town, numerous wind generators can be installed in a common area for the whole community. So everyone can benefit from lower utility bills, and you do not have to worry about the towers getting blown over in a storm.

You could also look into other forms of renewable energy to run your house. If you have enough sun in your area, consider installing solar panels as a back up for your wind generator.

You can read more from Steven C. Jones on his blog about wind generators and renewable energy.

Solar Powered Racing Car

June 11, 2009 By: Admin Category: General

Cambridge University Loves Races

You have heard about the proverbial hairdryers, have you not? Those noisy types of mopeds sprawling the streets of suburbia?

Now the Cambridge University students have created a solar-powered racing car that travels at 60mph speed, using the same power as a hairdryer. The car is to be completed by summer 2009, in time for the World Solar Challenge, an annual gruelling race across the Australian outback, from Darwin to Adelaide. The Cantabrigian creation, the Bethany, is highly tipped to win the competition.

The Bethany’s power source is collected via silicon cells that cover the car’s top; under this top, the car will be an efficient electric device. The car itself looks sleek and shiny, and, thanks to such design, weighs mere 170kg, has a battery management control system in place, an energy generating braking system, and an energy-efficient hub motor. The team behind the car’s creation estimates that the car will take 50 times less power than a normal car running on petrol.

Cambridge University may be the second oldest in England, but it is likely to be the first when it comes to devising new ideas for cars. At least, they definitely hope to show how future green vehicles can be generated based on the Bethany model. To quote their spokesperson, “at a time when the automotive industry is being forced to look at a low-carbon future, our vehicle demonstrates the enormous potential of energy-efficient electric vehicle technologies”. About 75 students from across the Cambridge University have been working on the vehicle’s design and build. Their efforts were supported by a network of corporate sponsors, academics, and specialist advisors.

In the next months the racing team of four students will be testing the car across the Outback, working in four-hour shifts, to cope with the heat. During the race, though, the Bethany will be fitted with an advanced cruise control system. It will be automatically adjusting speed, depending on the changes to road conditions and weather. The only thing the drivers will be left to do will be to steer the car and stay alert.

Solar Products

Solar products are easily installed and do not require any wire hookup. You can move them around as the seasons change or as you experiment with different looks to your garden, paths, flowerbeds, pool, deck or dock. Consider solar powered path lights for a beautiful incandescent effect on your garden path. How about some gentle solar garden lights for the highlights in your garden – or a cluster of solar light sticks for a beautiful effect. Solar patio lights make your outdoor gathering space warm and inviting and most come with both amber and white light settings. Solar pool lights create an exquisite effect as they float on either pool or pond, throwing a soft glow onto the water’s surface. Solar power can also do the job when more direct lighting is required: for instance a solar flood light provides strong illumination for security and solar post lights provide a classic look but can also provide strong white light if needed.

Solar products are innovative mechanisms that help conserve energy, thus, help maintain the ecosystem. Solar products are environmentally friendly and are usually cost effective as well. Today, there are several solar power products in the market for our home and office use. Solar products include items such as solar hot water heaters, solar heating systems, solar panels, solar flashlights, small radios, solar calculators, solar battery chargers, solar lanterns, solar lighting, solar car batteries and much more.

Solar products are perfect for campers, hikers or anyone who spends lots of time outdoors. Thin-film photovoltaic technology is perfect for charging many consumer products, solar cell designs are a proven success currently being used in space, military equipment, and large grid systems.

Solar products are currently growing at over 25% annually. Sales of thin film solar products are growing at over 33% annually. Most analysts project that thin film solar markets will continue to grow faster than traditional silicon wafer markets. In order for the solar industry to supply the amount of solar product needed to meet market demand, exponential growth rates will become endemic for at least the next decade.

New Solar Technology Trends Around the World

Executive Summary about Solar Technology by Philip Richards

In the business of solar energy, the U.S. has not been the biggest buyer of solar power. While the U.S. does quite well exporting solar panels and solar technology, there are many Americans who still find the cost of panels very prohibitive. As the price of solar energy decreases, Europe has had a much higher demand for solar power than anywhere else in the world. Many European universities and campuses have rebuilt their dorms to run off solar energy. Most water heaters in Europe are solar-powered, even if the home doesn’t have a full solar panel system.

In Europe, it’s not just small residential power systems that are leading the way in solar energy dependence. Specifically, Italy, Greece and the Czech Republic are the newest customers of solar power systems. These countries have begun to purchase so much solar energy that their borders have seen changes in tariffs for solar panels. Japan, who’s also been at the forefront of solar panel imports, has picked up solar panel buying as the cost of gas and electricity rises. There are entire neighborhoods in Japan outfitted with residential solar power panels. For example, the neighborhood of Iwaki New Town has about 46 homes outfitted with full private solar power panels. Japan also uses solar energy in surprising places. Japan is the only country to power most of its vending machines with solar energy. Sharp, one of the largest solar panel producing companies in Japan estimates that by 2010, Japan will produce 4.8 million kWh of solar energy.

The Race For New Solar Technology Is On
Executive Summary about Solar Technology by Winifred Churchill

Companies around the world are beginning to seriously consider the POWER of solar power.

In Mexico a solar dish is being tested. The expanding and contracting hydrogen gas drives pistons which power a generator which creates electricity.
A new thin-film technology is being used on the windows of high-rise apartment buildings and skyscrapers to collect the sun’s power for use in the buildings. It is attractive and not nearly as expensive as regular solar panels.
Thin-film is attracting major manufacturers around the world.
New solar technology is using crystalline silicon cells for solar power panels.

One criticism of solar energy is that it cannot be relied upon for a steady supply of energy, but there are projects underway which are addressing that issue. In short, solar technology is going the way of the computer industry or cell phones. Now you get the same functionality available in personal computers on tiny cell phones. The new silicon cells for solar panels may bring a similar revolution to solar power making it a reliable, clean source of energy.

Home Solar Electricity – What to Know Before Purchasing Anything

Executive Summary about Solar Electricity by Melanie Crouse

There are even tax rebates available in many states for families that are converting to home solar electricity. If you’ve been thinking of using PV (photovoltaic) panels for your home solar power, but are finding that it is too expensive, there are other options. There are many green energy suppliers that provide power from various renewable resources, such as solar electricity, wind power and hydroelectricity. If you’ve decided that solar power is the way you want to go, you will need to determine your actual power needs first.

The first thing you need to determine is how much electricity you need your home solar electricity system to generate. Do you want a grid-tied system where you are still connected to the grid, using a combination of your own solar power and the power supplied by the utility company? Or you can combine your own home solar electricity system with the grid, selling back any excess power that you don’t use to the power

The High Costs of Solar Electric Power

Executive Summary about Solar Electric by Klaus H Hemsath

Promotion of solar power generation is booming. Why are solar farms built when financial data clearly show that solar power is still the most expensive electricity generation technology available?

Solar power plant developers and marketers obviously know that they need to lower costs. Cost reduction is, however, expensive and takes time. There are two major technologies for solar energy conversion. Electricity production with steam is a very mature technology. The other technology is the direct, photovoltaic conversion of sunlight into electricity. This technology will most likely become the dominant solar electric power generating technology – eventually. The concentrated sunshine creates very high surface temperatures on the solar panel. To save solar panel area and make the solar panel price competitive, one must cool the surface of the solar panel very efficiently to prevent it from melting and destruction.

Present production costs for generating electricity with solar panels are hovering around $0.50 per kWh. Right now, solar power does not yet make economical sense.

None of the available technologies using renewable energy can compete with the cost of electricity generation from coal.

The technologies for generating electricity with solar power, wind power, marine power, and geothermal power are very well understood. At present, a respectable number of windmill farms and solar panel farms are being installed. Solar power does not make economical sense, yet. A random sampling of recent announcements of solar farm installations reveals that system installation costs are in the $3000 to $7500 per kW installed capacity. These plant costs loosely translate into a cost of producing electric power at $0.30 to $0.60 per kWh. This very unfavorably compares to the cost of electricity generation by any other technology.

As long as solar power constitutes only a very small fraction of overall electric power generation, the additional costs of storing intermittently produced electric power are not yet of concern. If the US is going to depend significantly on the intermittent production of electricity from solar power and wind power, it must begin to develop storage technologies for huge amounts of electric energy. Intermittent, renewable energies and electric energy storage are inseparable.

The Solar Electric Panel – An Inexpensive Way to Generate Electricity
Executive Summary about Solar Electric by Dan A Swanson

The solar electric panels, generally called solar photovoltaic panels, are made of a set of treated silicon cells arranged in a series array. They produce electricity on being exposed to the sunlight. A small solar electric panel will lessen the energy bills considerably, while a big solar panel will in fact budge the meter backwards. The contemporary solar electric panels are simple to install and are modular. The solar electric panels transform the sunlight to DC (direct current) electricity. Buy any of these solar electric panels according to your requirements.

Solar electric panels are the perfect answer to our increasing electricity bills and ever increasing reliance on depleting conventional energy resources. Make a one time investment in solar panels and generate free electricity for years to come. Solar electric panels are the need of the hour.
