Advantages of PERC Cell Technology

Solar photovoltaic manufacturing basics include several solar technologies, all of which are aimed to make the solar energy conversion process more efficient. It is well known that photovoltaic solar modules are designed to convert sunlight into electrical energy. The smallest element in a PV module made of various semiconductor materials is known as a cell. These are small, typically less than the thickness of four human hairs devices that are usually expected to produce about 1 or 2 watts of power. 

One of the technologies used in solar module manufacturing is to half-cut solar cells. In some sources, such modules are referred to in different ways, for instance, dual cells or split cells. These modules are designed with twice as many half-sized cells as the other types, regardless of the name. 

People may wonder why the solar panel manufacturing process may need to cut cells in half. The answer is rather straightforward; cutting solar cells in half results in up to a 3% increase in energy efficiency. The efficiency boost leads to better production per m², higher output and lesser power losses. 

The Perks of PERC Technology

PERC is another technology widely used in solar panel manufacturing.
Invented in Australia in the 1980s, the technology has gained popularity only in the past few years. Standing for “Passivated Emitter and Rear Cell”, the term refers to solar modules with an additional dielectric passivation layer, a reflective rear surface and aluminium contacts. Due to the reflective surface, absorbed sunlight rays instead of being wasted, get another chance to be absorbed and converted into extra energy. 

Despite a bit complex structure, PERC technology helps the manufacturers to produce solar modules with higher power capacity. Today, the greatest advantages of PERC cell technology with the help of PERC photocells, it is possible to produce modules with up to 370 W. Such modules work equally well both in sunny weather and in relatively low light. 

There are already other technologies on the market today aimed at improving the energy efficiency of solar panels. However, PERC technology is leading both in the world and in the local Armenian market. Armenian-made solar panels are manufactured according to international standards, standing out due to their high efficiency and competitive prices.

    First Armenian Manufactured All-Black Solar Modules! Soon!

    More and more businesses and private homes in Armenia have been switching to solar energy in recent years. Today, blue polycrystalline solar panels (solar panels types) are the most popular on the local and the world market. It is no secret that when choosing a solar system, preference is given to the efficiency and durability of panels - the more powerful the system, the greater the savings.

    However, sometimes it is also important to take into account the appearance of the solar system. 

    Black and Blue Panels. Main Characteristics

    The relatively affordable price of blue panels is caused by a simpler production process and lower installation costs. In addition, one of the advantages of polycrystalline solar panels is the absence of environmentally harmful waste during production.

    Black solar panels are mostly monocrystalline, rarely thin-film. Unlike polycrystalline solar panels, the price of black panels is higher due to the high quality of silicone used, production process waste and consumption of silicon.

    The outer PV layer and the framing of the monocrystalline panels are entirely black, unlike the "traditional" blue panels, the marked areas of which are white.

    Advantages of Black Solar Panels

    1. Black solar panels are more energy efficient

    Made of single silicon, monocrystalline black panels absorb several times more energy. It turns out that fewer monocrystalline panels are required to generate energy than producing the same amount of energy with polycrystalline panels.

    2. Stable operation in cloudy weather

    Even in cloudy weather, black solar panels do not stop absorbing light, providing a house or a building with constant electricity.

    3. Durability

    Compared with polycrystalline panels, monocrystalline panels are more durable. A number of global manufacturers guarantee 25 years of operation of their panels. LA Solar Factory gives a 25-year guarantee of uninterrupted operation of its products in Armenia.

    Monocrystalline Black Panels in Armenia

    The demand for the solar system in Armenia is growing every day. Solar systems of the world's leading companies are represented on the market.

    Armenian consumers will soon be able to purchase locally produced monocrystalline black panels as well. Being the first local manufacturer of monocrystalline panels in Armenia, LA Solar Factory offers its consumers the most efficient solar panels in the field of solar energy.
