Importance of Solar Power Contractors - Solar power can be direct as with photovoltaic or indirect as with concentrating solar power. All over the world people use solar energy for different purposes such as heating, cooking and now it is used to make electricity.
Solar power: Solar power
is the generation of electricity from the sun. Solar power can be
direct as with photovoltaic or indirect as with concentrating solar
power. All over the world people use solar energy for different
purposes such as heating, cooking and now it is used to make
electricity. Initially photovoltaic where used to power small size
applications such as calculators powered by a single solar cell and
now it’s been used off-grid homes powered by a photovoltaic array.
Solar power is an alternative and viable renewable source of energy
for our houses. Developing countries have started building solar
power plants.
Solar Roof Shingles:
Solar roof shingles are photovoltaic cells that produce electricity
from sunlight. At an average 86 inch long and 12 inch width and they
have an exposed area of 5 inch. However, the model vary according to
there requirement. Working of photovoltaic tiles Photovoltaic tiles
work by converting sunlight to electricity that can be used in our
houses. Photovoltaic cells consist of a positive and a negative
silicon slice placed under a thin glass slice. As the proton present
in the sunlight falls on the photovoltaic cell they knock the
neutrons off the silicon.
The silicon attracts the
negatively charged free neutrons but they are trapped by the magnetic
field that is formed from the opposing fields. Wires on the silicon
catch these neutrons and thus produce electric current when connected
to a circuit. The current produce will be direct current and hence it
must be passed through an inverter to produce alternative current for
home use. Energy storage method Solar powers are intermittent energy
source and hence it must be stored when they are available. Solar
power is not available at night and it is therefore necessary to
store them for continuous supply of electricity.
Thermal mass system can
store solar energy in form of heat at domestically useful
temperature. Thermal mass system generally use materials with high
specific hear capacity. Solar power contractors Installing a solar
power system is relatively expensive. And hence it is necessary to
choose the right solar power contractors. Solar power contractor that
you choose must have license and the required experience. Before
selecting a Solar power contractor there are certain things to be
noted: It is better to enquire several contractors before choosing
one. Checking with the local contract association for better result.
Ask for references. Once you have selected the contractor it is
necessary to find out if he will do the work from starting to end or
will there be any subcontractors involved. Solar panels need to be
properly wired to the converter box and its better to choose a
contractor who has some electrical knowledge.
Solar
power contractor can help you in: Designs solar power system for
your home: Most contractors will designs the required solar system
depending upon how much you are ready to spend. Get all the required
permits: Contractors can arrange the permits required faster. Project
schedule: Contractors work according to the schedule that you ask
for. Dealing with inspection: Solar contractors will be responsible
for the safety of the system. He will have to come and fix the
problem if the inspection fails. Quality control: An experienced
contractor will make sure everything is in place and in order. And
will also check air and water supply on the roof.
