Ecological and cheap energy from the sun

Using solar energy to produce electricity has many advantages. One of the biggest is the environmental aspect - it is a fully renewable source, which will not run out for many millions of years, and using it does not involve burning fossil fuels or producing hazardous waste. In addition, electricity from the sun is simply very cheap, which is an important issue in the growing popularity of this solution and is a decisive factor for many people. This method is relatively simple and does not require complex infrastructure - a big advantage compared to other green energy sources, such as those using wind and water or atomic decomposition energy, which are difficult to adapt for non-commercial use in homes, equipment or vehicles. One of the two most popular technologies used to produce solar cells is the use of silicon monocrystals.

Production and operation of monocrystalline solar panels

The production process of monocrystalline photovoltaic panels starts with the melting of high-purity silicon polycrystalline crystals at high temperature, leading to a relatively homogeneous mass. Then a crystal germ is placed in the crucible, around which the crystallization process takes place. After almost two days, one large crystal in the shape resembling a bullet or a cylinder is formed from the whole (this is why the monocrystalline cells are cut to an octagonal shape - this makes it possible to reduce material losses and, as a result, reduce production costs). It is characterized by high purity and guarantees free flow of electrons within it, which allows to produce more current from the same surface of the cells than in the case of polycrystalline panels (the greater the number of crystals, the lower efficiency). However, the complicated production process translates into a slightly higher price of monocrystalline panels. The last stage of production is to cut the crystal into slices and cut them into an octagonal contour, and then install protective coatings and wires.

Polycrystalline and monocrystalline photovoltaic panels

The choice between polycrystalline or monocrystalline photovoltaic panels is not obvious and depends on the intended use of the product and the user's needs. Polycrystalline cells are cheaper, but their efficiency is much lower (14-18% compared to monocrystalline, which offer as much as 16-23%). Therefore, obtaining the same amount of electricity requires a larger area of photovoltaic panels. Therefore, in projects and installations requiring the greatest possible compactness, monocrystalline cells are usually used. This type of solar panels also has a lower temperature coefficient, which means that they can be used at higher temperatures without significant power loss. For this reason, monocrystalline solar panels are often used in bright sunny locations or at higher latitudes, where average temperatures preclude the efficient use of polycrystalline cells (these, on the other hand, perform better in shaded, cool locations). On the other hand, the durability of both solutions is similar and depends more on the care and purity of the crystals used in the production process.

Our offer

In our shop you will find a wide range of monocrystalline photovoltaic panels for different applications. We offer, among others, products of the valued Polish brand Green Cell, whose power ranges from 300 W to 400 W. The devices can be combined both in series and in parallel, and their characteristics allow them to be used in many electronic projects, including photovoltaic installations, autonomous systems, mobile robots, electronic devices or vehicles with solar drive.
