Today, photovoltaic cells only contribute a small proportion (approximately 0.04 percent) of total electricity in the United States. At the same time the production of solar panels has growth rapidly per year by around 20% growth in the 1990s and photovoltaic panels prices decreases every year. Annual worldwide solar panel production (including solar panels with homemade solar power homes) is about 400 MW per year. Based on the total cumulative capacity figure, it is already reaching 2 GW.

So-called thin-film photovoltaic devices are usually based on mixtures of elements other than silicon — most notably copper indium gallium selenide (CIGS) — applied in a thin layer to plastic, even organic, components. Using nanotechnology and advanced materials science, thin film is able to produce power with a fraction of the materials. Similar techniques are being tried using ultra thin layers of silicon on a glass substrate, reducing what is now a 250 - micrometer (um) - thick wafer to less than 20 um. (more…)

In today’s tough economic times and with the increasing prices of gas and oil, finding alternative sources of energy should be our top priority. These alternative energy solutions are not only cheaper to install and maintain but also can help save our dying environment.

There are numerous sources of affordable and environmentally-friendly fuels available. You can opt for biofuels, hydroelectric power system, wind energy, or solar power system installed right at your very own home. Among these sources of energy, building solar power system is easier and the most viable one to achieve. (more…)

A home solar energy system can save you a lot of money on your household electric, gas and other bills. The sunshine is not only good for giving you a glowing tan in the summer, you can also enjoy the benefits of solar power in your home.

The resources we have been using for so many years are now running low by resources I am talking about fossil fuels. (more…)

Nowadays, solar power have become more affordable. That makes it a viable alternative energy option for homeowners who would like to save their electric bills each month and for the environmentally conscious who would like to take the financial benefit. Actually, the advantages of energy from the sun focus on global warming and independence from fossil fuels. (more…)

Solar energy is one the most popular renewable energy sources these days. Solar panel systems don’t even require much maintenance and still cut on electric bills month after month. A lot of people choose to make their own solar panels and others are buying ready-made ones that are quite costly. A single solar panel may cost as much as a few thousand dollars. (more…)

The sun and the wind provide us with solutions on how to cut down energy consumption. These are two great forces that are always available all year round. The most common and highly used alternative solutions today are solar panel systems and wind power systems. (more…)

The Home Solar Power System made its debut about two decades ago and has since flourished with the many advertisements touting the environmental and long term benefits. Over time, prices have since been dropping and systems have become a more reliable source of renewable energy. Yet, the installation cost still eludes the average common home owners. (more…)

Some people may doubt about the ability of these alternative power sources - to much like science fiction they may say. But then you can remind them that using the sun for heating to the point of combustion has been around since the time of the Greeks. The Egyptians used the sun to reflect on highly polished brass mirrors in order to light the interior of the pyramids for the workers to be able to see. (more…)
