Wash Your Solar Cells

To augment the energy supply, many are installing solar energy systems or residential solar panels. In general, these are flat units, placed at an angle on the rooftop. That naturally leads to the question of keeping them clean, which people equate to cleaning the roof itself. As this cleaning is usually left to the rainwaters, the next question comes as whether we should depend on the rains for cleaning the surface of the installed solar cells as well. Moreover, some also worry about whether water Read more [...]

Five New Advancements in Solar Cells

The earth receives a huge amount of sunlight every hour. Converted to electricity, this would amount to 52 PW/hr. This is more than ten times the entire amount of electricity produced per hour by China in 2013. In the same year, top countries of the world together produced only 16 PW/hr. of electricity. As this is much less than the actual potential of generation of electricity from the solar energy falling on the planet earth, several countries are actively engaged on research and development on Read more [...]

Transparent Harvester of Solar Energy

Common belief is anything that harvests solar energy must be non-transparent. Popular logic is if sunlight is allowed to pass freely through the collector, it cannot lead to energy production. Although this may be partly true for the visible spectrum of light from the sun, it must also be considered that the sun gives out radiations beyond the band of light visible to the human eye. Therefore, even see-through solar concentrators can successfully harvest energy from sunlight. Now, a team of Michigan Read more [...]

High Efficiency Hybrid Solar Cells

Normally, a modern silicon solar cell exhibits a maximum theoretical efficiency of about 33.7 percent. A majority of the sunlight falling on the solar cell – more than 66 percent – is not converted to electricity and is simply wasted in heating up the cell. Now, a new type of solar cells may be able to boost this efficiency to 95 percent or more. The University of Cambridge Cavendish Laboratories is researching on a new type of high-efficiency hybrid solar cell. The UK researchers are using Read more [...]

Can a Solar Cell Store Its Own Power?

Can a Solar Cell Store Its Own Power? Researchers at Ohio State University have invented a device that looks like a solar cell but has the ability to store the power it generates. The patent-pending device is the world's first solar battery. On October 3, 2014, the researchers reported in the journal – Nature Communication – that they have succeeded in combining a solar cell and a battery into a single hybrid device. The innovation is a special solar panel in the form of a mesh that allows Read more [...]

Solar powered LED light in a jar

We love finding products that make great use of solar electricity and our electronic components. How about a solar powered LED light in a mason jar? Perfect for your backyard porch or for mood lighting at a party - or even as a night light in your bathroom, bedroom or kitchen! The ones we found at MyGrillfriend.com give you a choice - it can be a soft deep orange colored light (referred to as a 'sun jar') or a beautiful shade of blue (called a 'moon jar') just by flipping a switch. The solar panel Read more [...]

How about a solar energy bikini for this summer?

We thought we'd seen just about everything powered by solar panels or solar film until we came across this bikini. Made by Solarcoterie, this bathing suit is made of photovoltaic film strips sewn together in series with conductive thread! With a USB connection you could be laying on the beach and powering your iPod at the same time. The suit is constructed of 1" x 4" solar strips which terminate in a 5V regulator and a female USB connector - perfect for powering your iPod. The down side is that Read more [...]

Solar Energy – a beginner’s look

Solar energy is an exciting field for both scientific study and home and office use, representing the modern drive to find clean, sustainable ways to power everyday life while protecting the planet for generations to come. Solar energy is created by the sun, which plays host to constant explosions of heat and energy. This energy radiates light that eventually reaches Earth, where water, land, and the clouds in the atmosphere absorb a portion. This light manifests as heat and helps to regulate Read more [...]

The New York Jets are green on and off the field

With the installation of an array of 3000 solar panels, the New York Jets have really set themselves apart from other professional sports teams. Their team headquarters and 120,000 square foot training facility will be powered by the solar panels that will generate an estimated 750,000 kilo-watt hours of electricity. Other sports teams have installed alternative energy systems at their training camps and stadiums, but the system at the Jets facility is the largest to date. The New York Read more [...]

The future of solar power: Flexible solar panels

As the popularity of solar energy grows, so does the selection of solar equipment that is made available. The big trend in solar energy right now is flexible panels. Flexible solar panels have many advantages over traditional framed solar panels. The flexible solar panels are lightweight so there is less worry in the installation process and during use. They can also be installed on a semi-permanent basis because they are very easy to remove and install elsewhere. Probably the biggest advantage Read more [...]
