A solar power system consists mainly of solar panels, an inverter, a meter, the consumer unit and the cabling.
The solar panels also called an array, are made up of photovoltaic (PV) cells. The array is usually mounted on a roof so that it is receptive to sunlight.
The photovoltaic cells in it are normally made of very thin layers of silicon and look like black or blue tiles. When sunlight reaches the cells, an electric field gets formed. The brighter the light, the greater the amount of electricity generated.
This direct-current (DC) electricity is then transferred to the inverter, which turns it into alternating current (AC) which you can use for your industry or business.
Let’s take a look at the technology powering the solar panels in more detail.
Monocrystalline (Mono) cells
Photovoltaic cells can be of different types. Monocrystalline cells (Mono) are made from very high-quality single silicon crystals.
They are highly efficient, perform better in low light conditions than other types of solar cells, and have a lengthy lifespan.
Polycrystalline (Poly) cells
On the other hand, polycrystalline (Poly) cells are made by fusing together several kinds of silicon crystals. These are easy to manufacture, are cost-effective, and produce less waste than Mono cells.
However, over recent years, rapid progress in cell manufacturing processes have started to bridge the gap between the manufacturing costs of Mono and Poly cells. In 2018, Mono solar modules comprised 50% of global photovoltaic cell production.
PERC technology
Traditionally, solar cells come with an emitter layer on the front and a dark coating on the back. However, Passivated Emitter and Rear Cell (PERC) is an innovation that has a dielectric passivation film on the back surface of the cells.
In PERC, the front directly absorbs sunlight while the back soaks in the reflected light, resulting in a higher generation of energy and greater benefits than the traditional solar cells.
It also affords more flexibility with more options for placement of the panels without affecting efficiency. PERC is available in both Mono and Poly cells.
Mono PERC Panels
When Mono cells and PERC technology are combined, the outcome is Mono PERC panels — solar modules of more superior quality.
The initial expenditure gets made up for in energy cost savings. What’s more, a fewer number of panels are required to be installed for the same amount of energy you receive.
They can capture more sunlight even in low light conditions and perform more efficiently than most other types of solar panels in the market. The need for such highly efficient solar panels has led to an increase in demand for Mono PERC panels.
