In the mid-1880s, Charles Fritts built the first solar cell formed by selenium coated with a thin layer of gold and with an energy efficiency of 1%. However, it was not until 1954 that Bell Labs discovered accidentally that would be the first commercial solar cell, with silicon as the base. (more…)

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.

Since the early 1960s, climate change and air quality have become major and often controversial issues in many countries and among groups from governments to various scientific communities. Prominent among these issues is the greenhouse effect, in which the gradually increasing tropospheric concentrations of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20) are believed to trap an excessive amount of solar radiation reflected from the earth. (more…)
Since preindustrial times, ambient concentrations of the greenhouse gases have exhibited substantial increases, inter alia CO2 ...

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…)

Residential Solar power systems are probably the safest, cleanest alternative for home energy consumption. Solar energy is renewable and never gets depleted as it taps on the UV wavelengths of sunlight. The process of capturing and converting the UV wavelengths into energy does not emit by products into the ozone and hence is an extremely eco friendly approach to generating energy. (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…)
