About Why can t photovoltaic panels be used directly for electricity
For this much talk about their benefits, it is important to discuss why they are not as common as they should be. Solar panels, which are sometimes referred to as photovoltaic (PV) panels, are panels that consist of solar cells that are used to collect and convert sunlight into electricity for power generation.

Solar panels, which are sometimes referred to as photovoltaic (PV) panels, are panels that consist of solar cells that are used to collect and convert sunlight into electricity for power generation.
Devices called inverters are used on PV panels or in PV arrays to convert the DC electricity to AC electricity. PV cells and panels produce the most electricity when they are directly facing the sun. PV panels and arrays can use tracking systems to keep the panels facing the sun, but these systems are expensive.
PV solar panels work with one or more electric fields that force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off for external use.
Solar panels can indeed be used directly to generate electricity from sunlight. In fact, that’s their primary purpose. Solar panels, also known as photovoltaic (PV) panels, convert sunlight directly into electricity using the photovoltaic effect.
The metal gridlines on a PV panel serve to capture and transport the electric current out of the solar cell and towards your home. The smaller metal contacts are called fingers, and they capture the electricity directly from the solar cell.

6 FAQs about [Why can t photovoltaic panels be used directly for electricity ]
Are solar panels a viable option for domestic electricity production?
Solar panels are appearing on more and more rooftops around our suburbs as solar photovoltaics (PV) become an increasingly viable option for domestic electricity production. Photovoltaic solar cells, such as those in these rooftop panels, convert light directly to electricity. Image source: Marufish / Flickr. But how exactly does it work?
How do solar photovoltaic panels work?
Solar photovoltaic (PV) panels are based on a high-tech but remarkably simple technology that converts sunlight directly to electricity. It's an idea that has been around for well over a century. In 1839, French scientist Edmond Becquerel discovered that certain materials would give off sparks of electricity when struck with sunlight.
What is a photovoltaic (PV) cell?
A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.
How do solar panels turn sunlight into electricity?
There are several ways to turn sunlight into usable energy, but almost all solar energy today comes from “solar photovoltaics (PV).” Solar PV relies on a natural property of “semiconductor” materials like silicon, which can absorb the energy from sunlight and turn it into electric current.
Do PV cells convert sunlight to electricity?
The efficiency that PV cells convert sunlight to electricity varies by the type of semiconductor material and PV cell technology. The efficiency of commercially available PV panels averaged less than 10% in the mid-1980s, increased to around 15% by 2015, and is now approaching 25% for state-of-the art modules.
How do photovoltaic cells work?
Photovoltaic cells are made of special materials called semiconductors like silicon, which is currently used most commonly. Basically, when light strikes the panel, a certain portion of it is absorbed by the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor.
