our natural resources and using renewable energy are more important
today than at perhaps any other time in human history. Using fossil
fuel-based energy sources has been proven to contribute to global climate
change. Clean energy alternatives like solar energy, collected through
photovoltaic systems, can be of great benefit to our environment.
Photovoltaic (PV) systems are used to convert sunlight into electricity,
which can then be used to help power your home or business. PV systems are
ideal sources of energy because there is a seemingly infinite amount of sunlight
for fuel, and there are no byproducts from converting the fuel into
electricity. Furthermore, once a solar system is installed, the electricity
produced is virtually free of cost.
Some of the best-known brands of solar panels are Sharp Solar,
BP Solar, and Kyocera Solar.
Other manufacturers of high quality solar panels include
and ET Solar.
All of these companies have proven track records of quality products. Some of the
best-selling solar panels on the market are the
Sharp 235W Solar Panel,
the Trina 235W Solar Panel,
the Uni Solar 144W Solar Panel, and the
ET 275W Solar Panel.
The amount of electricity that can be produced by photovoltaic systems
is dependant on the number and arrangement of the cells within the solar
panels. There are two methods of arranging these cells, series or parallel.
When arranged in parallel the current produced is equal to the total
of all the cells, but the voltage is limited to that of just one cell.
When done in series, the opposite is true.
Cells within photovoltaic systems are made from materials that act
as semiconductors, most commonly crystalline silicon. In the simplest
terms, sunlight is absorbed by these semiconductors, which begins the
flow of free electrons within the molecular structure of the material.
This flow is electrical current. When enough of these panels are connected
together they produce sufficient electricity to power a home or business.
The size of solar array needed for your home depends on how much electricity
you use on average, and whether you’re trying to disconnect from,
or reduce your dependence on, the community power grid. The more electricity
that is required, the larger the array will need to be.
Photovoltaic systems require sustainable access to sunlight. While
many solar panels are still capable of producing a small amount of electricity
even in overcast conditions, clear access to the sun is needed for maximum
production. Roof installations are very popular for this very reason.
However, on larger properties, ground-based solar arrays are not uncommon.
If you’re looking to convert your home to solar electricity,
purchasing high quality products is essential to getting the most life
out of your system. Researching various solar products can be invaluable
to the process. To ensure you’re getting the highest quality system,
be sure to look for certification from agencies like UL (Underwriters
Laboratories) and other similar organizations.
Most quality photovoltaic systems are manufactured to last for upwards
of 20-30 years. They are designed resist moisture, wind, and excessive
heat or cold. However, proper installation is paramount if your system
is going to last. For this reason, many people recommend hiring professionals
to do the installation work. Most of these systems can be installed
yourself, but a professional can often avoid common pitfalls, saving
you time and money in the long run.
While the initial costs of solar energy panels might seem a bit daunting
at first, in the long term, the money you can save will greatly offset
the original cost of purchase. Once photovoltaic systems are installed
they can provide the homeowner decades of free electricity, even as
their neighbor’s utility bills continually rise.
