Using solar panels is one of the
best alternative means of getting energy that we need on
a daily basis. Electricity is something that we can
hardly live without. It powers our watches, our
computers, our homes and offices, and virtually
everything else. However, conventional electricity
supplied to our homes comes at a steep price. Our
monthly energy consumption bills are testimony to the
fact that a large part of our savings goes towards
paying these bills in order to ensure the uninterrupted
supply of electricity.
What if you had an alternative
source of electricity? What if you could ‘manufacture’
electricity right in your backyard (or on your
rooftop!)? By installing solar panels, you indeed can!
Solar panels receive and trap the sun’s rays and convert
them into various useful forms of energy. Electricity is
one such form of energy. The high-efficiency solar cells
that are available commercially at various stores are
made from industrially processed silicon. In fact,
purified silicon is one of the core ingredients of
making solar cells and solar panels. Manufacturing
purified silicon is an elaborate process requiring
professional equipment, high temperatures and a good
deal of expertise. All this is clearly beyond the reach
of the common man. However, if one were to ask me about
how to build solar panels at home, I’d say that it is
quite possible.
Homemade solar cells may not pack
in as much punch as their industrially manufactured
counterparts. However, these residential solar panels
can still be used to generate modicum amounts of
electricity that can power a range of applications in a
common household. Or if you want, you can also make
commercial solar panels to power the workplace. There
are simply too many alternative energy incentives for
you to ignore solar power.
Building
solar panels at home
Before going
into building solar panels, you need to know how to make
solar cells at home. The common material of choice while
making solar cells at home is not silicon, but cuprous
oxide. In fact, cuprous oxide is one of the first
materials that were discovered to display the
photoelectric effect wherein light causes electricity to
flow in a material. Cuprous oxide belongs to the family
of substances called semiconductors. In every
semiconductor, a gap (often referred to as a
bandgap)
exists between the electrons that are bound tightly to
the atom, and those that are located farther from the
atom, which can move freely and conduct electricity.
When sunlight excites the electrons in cuprous oxide,
some of them gain enough energy from the sunlight to
jump past the bandgap and become free to conduct
electricity.
If you’ve never
built a solar panel before, or are just starting out on
the fascinating subject of solar energy harvesting, you
are well advised to keep with you a good guidebook. A
step-by-step manual will not only help you get started
on the right path by helping you find the best place in
your home or the workplace, but will also show you how
to save money by showing you where to buy cheap parts
from. The guidebook will also help you install such a
system and complete the wiring. And you will also need
to know about the safety instructions. Such a guidebook
offers a great way of ensuring your success with solar
panels.
