Why Are Solar Panels So Expensive? Factors That Affect Cost
Perhaps the number one thing stopping so many people from converting
to solar power is the expense. While
it is still rather expensive, it is important to understand that prices
have dropped over the past few years. In addition, you have to take
into consideration the amount of money you will be saving on your
electrical bill. Why are solar panels so expensive?
In order to determine how much solar panels will cost for your
home, there are several things you have to look at. The first thing
you have to look at is how much power your house consumes on average.
Every home is going to consume a different amount of power. This
affects the number of panels you will need for
solar home heating
(and solar water heating
too, if you decide you want your entire home powered by
The next thing to take into consideration is the
location of your home. So many factors affect the
solar panels. These factors include the number of sunny
days, rainfall, temperatures, how many hours of sun per day,
how much shade you have in the area where your panels are to
be installed, and even how windy it is (wind kicks up dirt
and debris, which can decrease the panel's effectiveness).
To determine how much power your home consumes on average, you
have to take into account things like the refrigerator, lights,
computer, TV, stereo equipment, motors in fans and washers, hot
water heating, and the household's basic heating needs.
The expense comes into play because solar panels aren't 100%
efficient - in fact, they're significantly less! (at the time of
writing, the highest efficiency achieved is 42.8%) This means
you need more solar panels to power your home than you would if
the efficiency were greater... plus, the more power you need, the
more panels you need. If your panels are going to be located in
an area where efficiency is further compromised by shade, wind,
and other factors, then even more panels may be required to
provide the energy you need. The cost can easily continue to
add up. To make it a little more inexpensive, "handy"
people might decide to build
your own solar panel.
However, many people cut down on their energy consumption, in
line with the whole objective of being eco-friendly. Plus once
the initial investment is recouped through energy savings, you
can continue to draw energy from the system for free.
