Solar Photovoltaic (PV) Energy
|
|
|
|
In one hour, the earth
receives enough sunlight to fuel every individual,
business, and government in the world for more than a
year. This energy can be easily harnessed for practical
purposes such as heating homes, running factories, and
powering industrial plants. The uses can be as varied as
the uses of energy itself. After all, solar electricity
is a renewable source of energy that will not decrease
with use. And the great thing is that whatever you use
today will in no way decrease the amount that can be
used tomorrow, next year, or in a hundred years.
At Hannah Solar, our
technologies convert sunlight into electricity using
photovoltaic (PV) systems. PV systems release no
greenhouse gases into the atmosphere and don’t even need
direct sunlight to produce energy… they just need
daylight, which means they even operate on cloudy days. |

Why Our Photovoltaic Technology Works So Well
|
|
Our PV systems use
individual cells that convert sunlight into electricity
you can use immediately. Solar, or PV, cells are most
commonly made from crystalline silicon. Each cell is a
wafer thin disc that has been subjected to a process
called doping. This process turns the silicon from an
insulator into a semi-conductor.
When light from the
sun hits the solar cells, it excites electrons within
the cell. Some of those electrons break free, and are
channeled through a conductive metal strip to create an
electrical current. This current can either be stored in
a battery or used directly in the form of electricity.
The process is clean, fast, and noiseless. And best of
all, there are no moving parts… no materials are needed…
and no chemicals or pollutants are created. It’s the
perfect energy solution.
From there, our solar
cells are connected together and encased in a protective
shell behind a sheet of glass to form a module or solar
panel. Each panel is self-contained with a metal frame
and equipped with connectors. As a result, it can be
transported and installed safely and easily. |

Supplementing Your Service
|
|
During the day, your solar
electric system from Hannah will be providing most (or
all) of your electrical needs. How much will depend on:
• The intensity of the sunlight (less power is produced
during winter months and/or cloudy days)
• The appliances or machinery you are running at the
time
If your
solar system is not providing all the power you need,
the balance is automatically provided by your utility
company. For instance: At night, your utility company
automatically provides your electrical needs. |

Battery Storage
|
|
Off-grid, or stand-alone,
solar systems produce power independently of the utility
grid. They are most appropriate for remote or
environmentally sensitive areas. For example,
stand-alone systems can provide farm lighting, fence
charging or solar water pumps. Most of these systems
rely on battery storage so that power produced during
the day can be used at night. |

Make Money with Net Metering
|
|
On days when sunlight is
intense, your system will likely produce more power than
you need. In this case, you can make money on that
leftover energy through “net metering.”
Net metering means the
extra electricity you generate can be used to offset the
power you use from your local utility company. This
surplus power will actually spin your electric meter
backwards, thereby giving you credit for the excess!
With all the
advantages of Hannah’s photovoltaic technology, your
solar electric system will be a valuable asset. Be sure
to ask your Hannah representative how you can take full
advantage of energy storage and net metering. |
