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…)

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…)

Photovoltaic solar energy once part of industrial phase are absolutely necessary to cut down its production costs for meaningful photovoltaic implementation in the multi energy sources. According to Reuter’s reports the prices of crystalline solar panels have declined from the 4.2 USD / Wp to the current 2USD/Wp. (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…)
