The photovoltaic effect is the photoelectric effect characterized by the production of an electric voltage between two pieces of a material that are in contact and exposed to light.

Photovoltaic cells are semiconductor devices that generate an electric current with sunlight.

Although solar panels have become more of a consumer good, there are still significant differences among them. These differences are not so much based on the product itself, but rather on the manufacturing company that backs the long-term warranties of the solar panels. Secondary ideas like this one, it would be of no use for a solar panel manufacturer to offer a 25-year warranty if, after 5 years of selling us our solar panel, they no longer exist. There will be no one to back our warranty.

The most important factor in correctly assessing the purchase of a solar panel is not so much the geographical location where it was manufactured. In the world of solar panels, there is a manufacturer that holds a 65% share of the global market, not only because it is the largest solar panel manufacturer, but also because it manufactures the photovoltaic cells used by the rest of the market. This manufacturer is LONGi, with an annual revenue of over 12 billion USD, which according to Bloomberg New Energy Finance, makes it the strongest company in the world to support long-term warranties.

LONGi leads the technological race to increase the efficiency of its solar panels, having set the world record for efficiency for a photovoltaic module in 2022. This refutes the idea that all panels are the same and indistinguishable from one another.

LONGi has production factories in China, Malaysia, and Vietnam.
