Home solar panels
There is more than one type of home solar panel on the
market. In fact, there are two main types: crystalline modules and amorphous
modules. Before deciding which you want for your own home, find out
the advantages and disadvantages of each.
Amorphous Photovoltaic (PV) Modules
These home solar panels take up more space than their crystalline PV
counterparts, but they are generally considered to be more aesthetically
pleasing. There are standings-seam thin-film amorphous PV laminates
that can easily be bonded directly onto a metal roof. This makes a uniformly
dark surface that does not detract from the overall beauty of the home.
Two main benefits of amorphous home solar panels is that they are less
affected by high temperatures and partial shading as crystalline panels
are. When just one crystalline solar cell is shaded, the flow electricity
in that entire series is blocked. Amorphous home solar panels, on the
other hand, have weblike series of connection that can bypass the shaded
areas.
Of course, the majority of these home solar panels do not have as long
of warranties as their crystalline counterparts (they are a newer technology),
and they a slightly poorer efficiency. Of course, as technology changes
and improves, the warranty will likely go up, as will their efficiency.
Crystalline Photovoltaic Modules
This type of home solar panel can further be divided into two types:
mono and poly. Monocrystalline home solar panels are generally thought
to be the least aesthetically pleasing of all – the dark solar
cells often have a white backing that is visible around each solar cell
corner. They are the first generation of solar cells and have a great
conversion rate. But they are expensive to make and it takes a lot of
energy to obtain the pure crystal needed to make them.
On the other hand, polycrystalline cells are much more appealing to
homeowners – they completely cover the white background. Thus,
no visible pattern is apparent: polycrystalline home solar panels have
a uniform appearance. Generally, polycrystalline cells have a slightly
lower conversion efficiency than monocrystalline solar cells, but they
use less energy to make and cost less to make.
However, as mentioned above, crystalline home solar panels do not take
up as much space as amorphous PV; they work more poorly in the partial
shade; high temperatures affect them more; and the their warranties
are generally longer.
