What Are Photovoltaic PV Solar Panels?
Modern Photovoltaic PV solar panels enable the average homeowner to generate large amounts of power for free each day and lower their cost for electricity. These newer panels are less expensive and more powerful than ever and can generate all the power your home needs for a reasonable investment. Even though most PV solar panels may seem similar, there are differences between them that affect how much power they can generate for your home. Knowing these differences can help you design the perfect solar power system for your home and spend your money wisely.
The good news is that these newer PV solar panels have become much more efficient and durable over the years and can produce an abundance of power under almost any sunny conditions. This was not always the case as older PV solar panels had a difficult time converting anything but strong and direct sunlight into useful power. This limited their use to homes that had the perfect exposure and alignment to the sun for a large part of the day. Because these newer panels utilize higher efficiency components, they cannot only produce more power but can also be used on more homes than ever before.

At the heart of every Photovoltaic PV solar panel is a collection of amazing devices called solar cells. These are the component of any solar power system that does the actual conversion of sunlight to electricity. In large part they determine how efficient your system will be and also how much power you can expect it to generate in a given day. Initially these solar cells were made from expensive and exotic materials like selenium that was able to convert a small portion the sunlight that struck it to power.
Even though the early solar panels that used these types of solar cells could technically produce power, they were far too inefficient and expensive for most residential applications. As the science around the photovoltaic effect improved, other more efficient and less expensive materials were used to produce these solar cells. Modern solar cells are made from a compound that is based on a silicon substrate and allow most panels to produce several times the amount of power from a given day’s sunlight than older panels. When choosing a PV solar panel for your home, try to find one that uses the more efficient monocrystalline solar cells if you can.
In addition to housing and protecting these fragile solar cells, the PV solar panels also contain wiring to connect them together into a grid. Even though each of the individual solar cells can each generate power from sunlight, the amount they produce is small. Because of this, they need to be combined together to increase their output from the solar panel and stabilize their voltage and power output to accommodate your system.
All of these connections are then presented to a standard connector on the PV solar panels that makes it easier to join them together and to other conversion equipment used in your system. Because these interconnects are now standardized, you can easily mix other panels together and even choose another vendor for the conversion and connection equipment needed to tie your solar power system into your home’s wiring.
