Alternative energy is actively popularized all over the world and in Ukraine. The environmentally friendly and promising sphere is constantly developing, so more and more varieties of solar panels appear.
If you want to use solar energy for industrial buildings or residential areas, you need to carefully study the features of different types of equipment in order not to overpay, but to get the right cost-effective panels for specific regional climatic conditions.
In the article, we will consider the common types of solar panels, their advantages and disadvantages, so that it is easier to choose the right equipment.
Monocrystalline silicon wafers are distinguished by a uniform dark blue surface color. They are made from the purest silicon, so they are the most efficient of all silicon wafers, and therefore more expensive than others.
The cost rises due to the fact that it is difficult to orient all the crystals in one direction. Monocrystalline solar panels show the highest efficiency only when the sun’s rays fall perpendicularly. Because of this, such panels are most effectively installed at heights or open areas. For the northern regions, it is better to choose other types of panels, but the closer to the equator, the more preferable is single-crystal panels.
Polycrystalline panels are characterized by an uneven blue surface color, since the crystals are oriented in different directions. To create polycrystalline panels, less pure crystals are used than for monocrystalline ones.
Thanks to multidirectional crystals, even with scattered light, a high efficiency is obtained. Polycrystalline panels are less efficient than monotypes, but generate more energy in cloudy weather.
Due to the heterogeneity of the material and the peculiarities of creation, the cost of structures is significantly reduced. If in the manufacture of monopanels it is necessary to orient the crystals in one direction, then when manufacturing polycrystalline solar cells, the directionality is not controlled, and after cooling, they are cut and processed.
Polycrystalline panels are installed on the roofs of public buildings and private houses, so they are in great demand in the market.
Thanks to thin-film technologies, low-cost solar panels are made. Thin-film panels are especially popular for large farms generating “solar electricity”, especially those with small budgets for purchasing panels and large areas of land dedicated to batteries.
Thin-film solar equipment is mounted on the ground, on roofs and even on the side surfaces of houses.
Thin-film panels are used for systems that generate energy directly to the grid. It is recommended to add high-voltage controllers and inverters for solar panels to the station package, which do not fit with household systems.
Silicon panels are made from amorphous silicon, and the process is different from that of crystalline hardware. A hydride is used rather than a pure material, so classic crystal formation does not occur, which reduces the cost of production.
Due to the structure of amorphous silicon, silicon batteries effectively absorb scattered light photons.
Silicon solar panels are ideal for northern areas where vast areas are empty. At high temperatures, the productivity of silicon panels is less than that of their counterparts, but still sufficient for domestic consumption.
Consider the advantages of each type of panels.
Advantages of monocrystalline solar cells:
The polycrystalline solar panel, in turn, has the following advantages:
Thin film solar panel:
When choosing solar panels, we recommend taking into account the disadvantages of one or another design
Monocrystalline are the most expensive and sensitive to air pollution. Dust scatters light even in sunny weather, which reduces the efficiency of equipment.
Polycrystalline panels have a reduced efficiency (compared to the previous type of batteries). Bulky, so more space is needed for installation.
Amorphous silicon panels also require large areas for equipment installation.
Thin-film panels are inexpensive, but due to their lower efficiency, they also require more space than their predecessors.
Each type of panel is optimal for specific operating conditions. If you do not know what type of equipment to choose, contact our manager via the website or by phone, and they will help you choose the appropriate type and configuration of the solar station.
The sun as an energy source In recent years, in many countries around the world, scientists have paid close attention to the development of power plants that use environmentally friendly “green” energy. And the most powerful and most accessible source of alternative energy is the Sun. With all these advantages, there are also disadvantages of […]
Every year people need more and more energy. The world’s population is increasing, consumption is growing and traditional industries cannot cover the growing demands. It is not only the economic aspect that matters. Traditional ways of obtaining energy are considered dirty, and the environmental problem is at the top of the issues of concern […]
Before calculating how many solar panels you need for a house, you need to determine what you are installing the modules for. For one, the main thing is to save on utility bills, for another it is an opportunity to invest and earn money, and for others, a solar battery for the home is needed […]
