Powering Up Kit Homes: Metal Roofing Solar Panels
When it comes to preserving the Earth’s environment and the limited resources, there are a number of things that individual can do.Some of the commitments that an individual can accomplish are to use less gasoline, purchase a hybrid or electrical car or ride a bicycle.In addition, there are some individuals who will be totally committed to recycling.
Another excellent way of conserving the Earth’s resources is by conserving energy. One of the powerful ways that a business or kit homes owner can accomplish this is through a two fold process.That twofold process is by installing metal roofing and placing metal roofing solar panels on the roof.
Therefore, it is important to know about metal roofing and the advantages of metal roofing solar panels.
Metal Roofing
Typically, when a kit home owner has had to replace a roof that has just simply worn out, they have replaced that roof with asphalt shingles or cement tile.However, the reality is that the replacement of a roof can be a costly upkeep for the home.Additionally, with the rising cost of energy and the desire of individuals to do more for the environment, there has been a significant push to address both of these issues.
Therefore, there are options available for the consumer.One of those options is to install a metal roof.The advantages of replacing a standard roof with a metal roof is that the product and installation is cheaper, saves the consumer on their energy bill, the roof has a longer life expectancy and is virtually maintenance free.
In addition, to maximize the placement of a metal roof, one may wish to install sheet metal roofing solar panels as well. Metal roofing solar panels are photovoltaic cells that are linked together and are designed to capture the energy of the sun.This energy is then converted into electricity to help meet the electrical needs of the kit homes owner.
Advantages
There are many advantages to installing metal roofing solar panels on to sheet metal roofing panels.Some of those reasons are financial in nature while other agreements can cite the preserving of the limited resources of the planet.
Financially speaking, if an individual installs metal roofing solar panels on their sheet metal roof they will pay less for their energy consumption.This is because the panels will capture the Sun’s rays and through photovoltaic technology will convert the Sun’s rays into usable electricity.
In addition, the technology of today provides metal roofing solar panels that are not cumbersome or are constructed of glass type panels mounted on a huge frame.The metal roofing solar panels of today are thin in nature and can actually be rolled out on to the sheet metal roofing panels.This process also adds to the financial savings of the individual.
Highly efficient oxygen catalyst found (MIT)
A team of researchers at MIT has found one of the most effective catalysts
ever discovered for splitting oxygen atoms from water molecules — a key
reaction for advanced energy-storage systems, including electrolyzers, to
produce hydrogen fuel and rechargeable batteries. This new catalyst liberates
oxygen at more than 10 times the rate of the best previously known catalyst of
its type.
The new compound, composed of cobalt, iron and oxygen with other metals,
splits oxygen from water (called the Oxygen Evolution Reaction, or OER) at a
rate at least an order of magnitude higher than the compound currently
considered the gold standard for such reactions, the team says. The compound’s
high level of activity was predicted from a systematic experimental study that
looked at the catalytic activity of 10 known compounds.
The team, which includes materials science and engineering graduate student
Jin Suntivich, mechanical engineering graduate student Kevin J. May and
professor Yang Shao-Horn, published their results in _Science_ on Oct. 28.
The scientists found that reactivity depended on a specific characteristic:
the configuration of the outermost electron of transition metal ions. They
were able to use this information to predict the high reactivity of the new
compound ...
