These systems are usually
to purchase (due to the fact that they do not require an
additional battery) and they are also the only type of solar system
that can actually make
you money in the long run, although their
ability to earn you money depends entirely on the options made
available to you by your local power company.
These systems are able to
earn you money through a process called net metering, and
more on that
will be covered a little later on. However, first we will look at
exactly what a solar grid tie system is and then we will move on to
discuss the benefits of this type of solar system, including net
What is a Solar Grid Tie
A grid tied solar system
is the term used to refer to any solar unit that is directly connected
to the local utility grid. This means that any energy
created by the
photovoltaic solar panels is fed directly into the local electricity
supply. A grid tied solar system generates electricity through the use
of its photovoltaic solar panels, and this electricity is then sent to
the home where it is either immediately used if necessary.
If the home is not using
electricity, or if the system is generating excess energy, then the
energy is then fed onto the local electricity grid. This means that
while your solar system is currently generating electricity, this
electricity will be used to power any and hopefully all electricity
needs that your home or office has at that time.
However, this also means
that a grid tied solar system is also unable to store any
created due to the lack of a battery. Therefore, whenever your grid tie
solar system is not generating electricity (such as times when the sun
is hidden by clouds, when the sky is overcast, or at night) then any
electricity needs that your home may have must come directly from the
local electricity grid.
Nonetheless, this does not
mean that a grid tie solar system cannot help you to achieve your goal of
zero net emissions. As long as you can generate more electricity than
you use, then you will still be able to use only the solar energy that
How Does a Solar Grid Tie
A grid tied solar system
is a photovoltaic solar unit that works through the use of silicon
solar panels that generate electricity when exposed to sunlight. The
electricity generated within these solar panels is then transferred to
the solar inverter.
A solar inverter is a
device that converts the direct current (DC) electricity created by the
solar panels into alternating current (AC) electricity which can be
used to power your home and any electronic devices within in. After
being converted into alternating current, the electricity then goes to
your home’s electricity panel, whereby it is then transferred to any
parts of the house currently using electricity.
Any excess electricity
then travels past the home or office’s electricity meter before passing
on to the power lines and into the local electricity grid.
energy created by the grid tie solar system passes by the electrical
meter, it actually causes the meter to roll back, whereas any energy
coming from the grid into the building’s electrical system causes it to
roll forward resulting in energy charges.
is Net Metering and How Can You Benefit From It?
Net metering is a program
offered by many electricity companies around the world which will pay
the home or business owner for any excess electricity that they create.
However, this does not always mean that you will earn actual money
through this process, as many electricity companies will only reward
you in the way of credits on your energy bill, although, some do still
pay real money for the excess energy.
This means that even if
your home is completely carbon zero, you still may not earn any
tangible cash for the excess energy you create, but at least you can
feel comfortable knowing that others will be able to use your excess
solar energy so you are still making a difference in helping to reduce
pollution and CO2 emissions.
Before installing any grid tied solar
system, you should be sure to check with your local utility company to
see what, if any, type of net metering program they have to offer
Who knows? Maybe you will
be one of the lucky ones and live in an area where you can earn real
money for your excess electricity. If this is the case, all you have to
do is sit back and wait for the checks to start rolling in due to the
excess of free electricity that your home or business is
Either way, the entire
system should pay for itself in only a few years due to the fact that
you will be saving so much money on your electricity bills. Even if you
cannot afford a large enough system to generate enough electricity to
power your home, any size of solar system will still go a long way
towards helping you to reach energy independence while also helping to
reduce the amount of pollution as well.
