PV modules
The market offers us a really wide selection of various types of PV modules. let's find out which ones are the best and what they are good for.
Our choice - the most trusted modules on the market.
The choice of photovoltaic modules is not easy, they differ in size, maximum power, technology and appearance. The basic selection parameters, which we always remind our customers about, also include the warranty and temperature efficiency. The modules we choose are partly on the world's Tier1 list, i.e. the most trusted manufacturers, but there are also SunLink modules discovered by us, less known, but of great quality and warranty. At the investor's request, we are able to order and install any module available in the country. Below we present the most frequently installed PV modules by our company.
Photovoltaic is with us everywhere
- not only on the roof
Our home installations have been dominated by monocrystalline half-cut modules with power ranging from 350-450W. Below we have prepared a short summary of the different types of modules for you, so that you know what is available on the market and where else you can use this fantastic solution which is the production of energy from the sun!
Monocrystalline module
Monocrystalline modules are a fairly new technology and generate more power and better yields than polycrystalline modules. They have already become a standard on the market, we can distinguish them based on the characteristic black color of the cells. They usually come in two types, in halfcut and full black technology.
Usage: Used primarily in roof and ground installations.
Advantages: Low price to power ratio [PLN/Wp]. Bypass diodes, busbar technology.
Defects: The black color of the full black modules causes higher heating and thus lower efficiency of the module in the summer.
Polycrystalline module
Polycrystalline modules are the previous generation of photovoltaic modules. They have a lower power factor and slightly lower efficiency. However, they are better at shading. More and more often, the installation of such modules is abandoned, mainly due to the low maximum power
Usage: As in the case of monocrystalline modules, they can be found in roof and ground installations.
Advantages: Very attractive price per power. Good shade tolerance
Defects: Low maximum power. A large area is needed to obtain a large installation power.
Bifacial module
A variety of monocrystalline modules that have photovoltaic cells on both sides of their surface - usually made in glass-glass technology. This allows you to generate electricity also from the light reflected on the other side of the module.
Usage: They are most often used in ground installations or tracking systems, especially with white aggregate bedding under the structure. It makes no sense to use such modules on roofs.
Advantages: Very high maximum power
Defects: Narrow range of use, only installations where we allow the access of reflected light to the other side of the module.
Railing module
Photovoltaic balustrades are the perfect solution when we care about the greatest possible aesthetics when we want to obtain energy from the sun in sometimes even unconventional places. Most often performed in office buildings on balconies or in multi-family buildings
Usage: Photovoltaic railings perfectly replace ordinary railings in places where the annual insolation has a sufficiently high value. They are also used for practical decoration of the walls of buildings.
Advantages: A wide range of applications for this type of modules, and in addition, in terms of design, we can choose from a whole range of colors and patterns
Defects: Due to their construction and design, they are more expensive than standard PV modules. Installation prices for such installations can be much more expensive due to the mounting techniques and systems.
Triangular module
Triangular modules are nothing more than ordinary PV modules with a changed shape and are perfect when we want to make the most of the roof surface.
Usage: Wherever the so-called envelope roof and we want to make the most of the roof surface. What's more, the installation is more aesthetic and less stands out against the background of the roofing material.
Advantages: They allow us to use 100% of the roof area, increase the efficiency of the installation
Defects: Due to their reduced surface area, they have lower efficiency than modules with standard dimensions
Modules for off-grid motorhomes
On the market, we can find various types of PV modules of various, non-standard sizes and shapes. Many of them are ideal for use, for example, for off-grid installations in a motorhome, where we need to perfectly match the size to the space we have.
Usage: Non-standard PV modules will be used in places where the area of a standard module could be too large.
Advantages: They allow us to use the surface on which the installation of a standard PV module would be impossible or inadvisable.
Defects: We won't fit many of them on a small roof area. They are used more to recharge the batteries than for current needs.
Flexible modules
Flexible photovoltaic modules are used primarily on yachts, boats or caravans. They are also resistant to sea salt and UV radiation.
Usage: Flexible modules are used primarily on yachts, they are also used on motorhomes.
Advantages: Light, flexible, attached with glue, so there is no need to disturb the structure of the boat or car. They bend without problems up to 15 degrees.
Defects: Due to the type of mounting (adhesive), servicing the module is difficult.
Folding modules
Foldable PV modules are most often used by people who value the ability to charge electronic devices wherever there is no civilization. They will definitely be useful when fishing, camping or on the trail. Very often combined with portable energy storage.
Usage: Due to its construction, we can place them on any flat surface as well as on a curve.
Advantages: Lightweight, they fold to the size of a shoulder bag
Defects: Quite low power, rarely exceeding 100Wp
