Every day from sunrise to sunset on our house roof is exposed air to heavy sunlight, which heats up our roof. When the roof
heats up, it also heats up the air underneath the roof which we call the attic. Attic air is the air found directly below the pitched
roof of a house or building. As the hot air accumulates within the attic, it slowly radiates the heat to your rooms and your whole
house eventually gets hot and humid.

EVER WONDER

1) Why it is so hot during the day even after you turn on your celling fan?
That's because your celling fan is blowing all the hot air from the extremely hot attic downwards.

2) Why does your air-conditioner takes longer cool your room during a sunny day than a raining day?
That's because your attic is heated up and rises 8 to 10 degrees above the ambient temperature.

Now with Solar2Cool Extractor Fan, it removes all your trapped hot air in your attic bringing new and fresh cool air into your
attic. A 16" Solar Extractor Fan can remove up to 24,000 liter of hot air per minute, keeping your attic cool all day long.

From sunrise, the extractor fan starts to work till sunsets, bringing down your attic temperature as much as 5 degrees. All
these require Zero maintenance, Zero electricity and it works all year round with a 5 years warranty from Solar2Cool.
   
How Do Solar Panel Work?

A solar panel is a device that collects photons of sunlight, which are very small packets of electromagnetic radiation energy,
and converts them into electrical current that can be used to power electrical loads.

Using solar panels is a very practical way to produce electricity for many applications. The obvious would have to be off-grid
living. Living off-grid means living in a location that is not serviced by the main electric utility grid. Remote homes and cabins
benefit nicely from solar power systems. No longer is it necessary to pay huge fees for the installation of electric utility poles
and cabling from the nearest main grid access point. A solar electric system is potentially less expensive and can provide
power for upwards of three decades if properly maintained.

Besides the fact that solar panels make it possible to live off-grid, perhaps the greatest benefit that you would enjoy from the
use of solar power is that it is both a clean and a renewable source of energy. With the advent of global climate change, it has
become more important that we do whatever we can to reduce the pressure on our atmosphere from the emission of
greenhouse gases. Solar panels have no moving parts and require little maintenance. They are ruggedly built and last for
decades when properly maintained. Last, but not least, of the benefits of solar panels and solar power is that, once a system
has paid for its initial installation costs, the electricity it produces for the remainder of the system’s lifespan, which could be as
much as 15-20 years depending on the quality of the system, is absolutely free! For grid-tie solar power system owners, the
benefits begin from the moment the system comes online, potentially eliminating monthly electric bills or, and this is the best
part, actually earning the system’s owner additional income from the electric company

The solar cells you would have seen on satellites, calculates etc are photovoltaic cells or modules (modules are a collection of
solar cells electrically connected and joined together in one frame). Photovoltaics, (photo = light, voltaic = electricity), convert
the energy of sunlight directly into electricity. Originally expensive and only used in space, photovoltaics are now finding many
applications on countless devices,buildings etc were ever remote or free and environmentally sustainable produced electricity
is required.
Photovoltaic (PV) cells are made of special materials called semiconductors like silicon, which is currently the most commonly
used. Basically, when light shines on the solar cell a percentage of this solar energy is absorbed into the semiconductor
material. This energy now inside the semiconductor knocks electrons loose allowing them to flow freely. PV cells also all have
one or more electric fields that  force electrons freed by light absorption to flow in a certain direction. This flow of electrons is
an electrical current. Metal contacts on the top and bottom of the PV cell draw that current off to use to power external
electrical products such as lights, calculators etc. This current ,combined with the cell’s voltage (which is a result of its built-in
electric field or fields),determines the power (or wattage) that the solar cell can produce.

Solar panels collect clean renewable energy in the form of sunlight and convert that light into electricity which can then be
used to provide power for electrical loads. Solar panels are comprised of several individual solar cells which are themselves
composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive
charge). Solar panels absorb the photons and in doing so initiate an electric current. The resulting energy generated from
photonsstriking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the
electric field generated by the solar cells

An average home has more than enough roof area for the necessary number of solar panels to produce enough solar
electricrity to supply all of its power needs. Assisted by an inverter, a device that converts the direct current (or DC current),
generated by a solar panel into alternating current (or AC current), solar panel arrays can be sized to meet the most
demanding electrical load requirements. The AC current can be used to power loads in your home or commercial building,
your recreational vehicle or your boat (RV/Marine Solar Panels), your remote cabin or home, and remote traffic controls,
telecommunications equipment, oil and gas flow monitoring, RTU, SCADA, and much more.
