Today, most people are already familiar with the solar power panels in the roofs of houses and
around business areas.
However, it is also true that the majority of the population have only a vague idea of how these
devices work, let alone all the forms they can possibly take.
While it is not uncommon to see panels affixed to roofs in residential neighborhoods, these are
not the only solar power panels you find out there.
Solar panels can change quite a lot regarding the design, the dimensions and visible look, but
at the same time all these solar power systems are generally created
according to a small number of basic thematic patterns.

Let's now see: How do solar panels work?
If your goal is to collect the sun's ray power to provide energy for a house, electronic device or perhaps a
complete business building, solar power panels are usually devised in such a way that they can perform the
following tasks:
- Collect the energy of the sun - The mission of the installed solar panels or entire arrays is to
harness the sun's photon power. Most of the times these systems are built using silicon like the needed
semi-conducting medium.
- Convert it to electricity - Once a solar panel absorbs the sun's photon energy, the electrons, or
negative charges, are set free from their atoms. This is what makes it possible for them to travel through the
semiconductor medium to generate electricity. This electricity is converted by the solar power panels into
direct current, or DC electricity. At this point, the DC electricity is sent off to an inverter to be converted
to AC electricity or alternating current electricity.
Popular solar power panel arrays
As we know, there are many variations of solar power panels regarding their capacity and size. Among the more
known systems we find the following:
- Designs of solar cells - This is a solar system with very limited dimensions. It is designed to
function exclusively with one small appliance. For instance, it is not uncommon that a portable radio that
works with solar power uses only one solar cell and one single rechargeable battery. A cell is also the basic
component of full solar power panel designs.
- Solar panel arrangements - All those rectangular dispositions that you see in the roofs of
residential areas are for the most part solar panel arrays. This implies that there are quite a lot of
solar power systems that function simultaneously to supply
electricity to specific systems in a home or an entire house. Note that all of these solar power panels are
built with many individual solar cells.
- Solar dish operations - This arrangement of solar power panels is not very common yet. Here we have
a system that instead of being affixed statically to a roof can be moved in some ways. The advantage of solar
dishes is that they can be rotated and adapted in order to harvest the maximum amount of sun's rays.
Solar power panels are the fundamental element of an energy collecting system that operates on a
higher-reaching scale. Each solar panel comprises many solar cells, each one of them conceived to absorb the
rays of the sun so that we can use them effectively as we go on about our lives. It would be a shame that our
societies continue doing as if solar power panels were not a real alternative energy system that can be added to
the range of possibilities in the fascinating renewable-energy field.
