Experts agree that solar energy is the future of electrical power. It is a safe, clean,
reliable source of energy that is completely renewable. How are these panels made, how
they work, and why exactly should you consider using them? Learn about solar panels below.
How Are Solar Panels Are Made?
The construction of solar panels is a very delicate and sophisticated process. It
the creation of crystals from rock and then the formation of very thin panels from that
In most cases, the first steps involve charging and then melting a large deposit of
polysilicon. Polysilicon is a unique type of Quartzite that has semiconductor
These semiconductor properties are what make it such a valuable ingredient in the
manufacturing of solar panels.
Large amounts of polysilicon are stacked together and given a positive electrical
After being charged, the polysilicon is locked inside a furnace and heated to extreme
temperatures of around 2,500 degrees Fahrenheit.
These high temperatures melt the rock down into a liquid-like substance. A silicon
is lowered via a cable into the melted mixture. The silicon crystal is then rotated in
direction while the mixture turns in the opposite direction.
The melted polysilicon slowly freezes into place on the silicon crystal and it matches
exact structure of the crystal. The end result is a massive silicon crystal that can
shaped and cut into thin wafers.
The thin wafers are then treated with various chemicals and mechanical processes that
them to properly conduct electricity from the sun. For example, phosphorous might be
to the topmost layer of silicon to provide a negative charge. Now that some panels have
positive or negative charge an electrical field can be established.
Finally, the wafers are encased in a glass frame and connected to a junction box. The
result is a fully functioning solar panel. This process has become significantly easier
more affordable over the years. That translates into better pricing for
How Do Solar Panels Work?
Now that you know how solar panels are manufactured it is time to look at how they work.
do these strange panels convert the sun's ray into usable electricity?
In simple terms, solar panels in Middlebury Center, PA are designed so that photons from the sun knock free
attached to atoms. Some of the freed electrons will move to the top of the cell. They
flow into metal conductor plates placed on either side of the panel. Electrons then flow
back into the cell to complete the closed loop.
Some extra steps may be required depending on what is being powered by the solar panels.
they are used to power homes or business that require alternating current (AC), then an
inverter must be used. An inverter is an electrical device that converts direct
to AC. Most appliances utilize AC. However, devices that are battery operated can be
Rather than passing through an inverter, the DC may also be used to charge a battery.
is most common when a house is completely “off the grid” and relies on solar power
the day and night. The panels charge the battery so that the home can be powered even
the sun is not out. The DC leaving the battery must still pass through an inverter
being used in the home.
What Are the Benefits of Solar Panels in Middlebury Center, PA?
Solar energy is the most efficient and sustainable source of renewable energy there is.
Moving from a reliance on fossil fuels to a reliance on natural energy from the sun has
- Environmental impact
That is only a few them. Let's take a closer look at these benefits.
The cost of solar energy is one of the biggest reasons why people either want or don't
to use the panels. On one hand, solar panels cost a bit to install. Costs have become
significantly cheaper over the years, but it still requires that initial investment that
some people just can't justify. On the other hand, it means never paying for electricity
again (if the house in Middlebury Center, PA is completely dependent on a solar power systems) or at least lowering the
electric bill dramatically.
Solar power should be looked at as an investment. Within a year's time, a set of solar
panels can easily pay for itself. More money can be saved if you are able to install the
panels yourself. The cost of solar panel installation is often as much as the panels themselves.
The environmental impact of using residential or commercial solar panels installations is another extremely important factor.
However, unlike the price, there is no counter-reasoning for this point. Solar panels
better for the environment no matter how you look at it. It isn't depleting the limiting
resources of the Earth and the production of electricity from solar panels does not
any harmful pollutants.
Traditional electricity cannot make the same claims. Power plants are responsible for a
large majority of the pollution that is damaging the planet. The are also steadily
the natural resources available. There is only a finite amount of fuel available on the
planet. A point in time will come when a new source of energy must be used. Solar power
still the best solution.
The above point also falls under sustainability. Fossil fuels and other limited sources
energy are not sustainable in the long-term. The sun; however, will be here for as long
humans are here.
As for efficiency, solar panels have come a very long way in this regard, especially in
last decade. Solar panels were not always considered highly-efficient and it would take
large area of panels to generate sufficient electricity to power homes.
Efficiency has increased and thus the number and size of required panels has decreased.
also results in a decrease in the cost of purchasing and installing the panels.
Why Wait For Your Middlebury Center, Pennsylvania Solar Panel Installation?
Don't wait to be the last person taking advantage of having solar power installed.
in Middlebury Center, PA Even if you don't go completely off the grid, having solar panel installers installing a few solar panels around the
home can save you money and lessen your impact on the environment.
