TommaTech® incorporates up-to-date technologies and lays great emphasis on our research and development effort to offer reliable state of the art products at affordable prices.
TommaTech®’s mission is to offer you the latest technology in solar panel production.
Please find the technologies which we currently incorporate in our solar panels as outlined in the sections of this page.
At TommaTech®, we offer brand new solar panels with multi busbar cell technology in cell architecture resulting in highly efficient panels for your needs. The multi busbar technology increases the efficiency of the solar panels with its new generation cell structure by minimizing both optical and electrical losses in the panel through reduced currents and smaller, round ribbons in the solar cells.
Following the latest trends in solar energy sector, TommaTech® manufactures multi busbar solar panels with higher yields on smaller areas. For example, our 9BB modules include 9 bus bars which are the silvery rods silk screen printing on the front surface of the solar cell, collecting the electrons in the cells and conducting them to the junction box. Compared to common solar panes, 9BB solar panels collect significantly more electrons, resulting in higher yields.
Bifacial modules generate solar energy from both sides of the panel. While traditional opaque backsheet panels are single-sided, bifacial modules reveal both the front and back of solar cells.
When bifacial modules are installed on a highly reflective surface (such as a white TPO roof or a floor with light colored stones), bifacial solar panels can generate up to 30% additional electricity due to the extra power generated from the rear of the panel.
Monocrystalline solar panels, made of single- (mono) crystal cells offer more power on the same area, thus reducing the number of panels for your solution as well as the installation time, materials and cost. The PERC technology reflects already transmitted solar radiation back into the cell, giving it a second chance to be converted to electricity, thus increasing the output of the solar panel.
The new generation flexible panels produced by TommaTech® are one of the latest in solar panel technology. TommaTech flexible solar panels can be installed on curved surfaces without compromising on the efficiency.
Flexible panels are ideal for boats, yachts, caravans, automobiles etc. It has been specially designed to adapt to surfaces with restricted, specially shaped or curved areas (up to 30°). In addition, since flexible panels are lighter than other panels, they are ideal for installations on roofs that cannot bear heavy loads.
With its BIPV (Building Integrated PhotoVoltaic) solar panels, TommaTech® offers you new options for using any available space to provide the cleanest and free solar power generation. Designed by our team of experienced German engineers, our standardized BIPV solar panels with 220Wp, 280Wp and 390Wp in different sizes are equipped with cutting-edge technology to serve your needs.
On-Grid inverters convert solar DC energy to AC electric energy to be sold to the national power supply or consumed by connected loads.
Off-Grid inverters store excess solar energy in a battery bank to support the solar panels during periods of reduced irradiation and to power connected loads at night. Unlike Hybrid inverters, they can not sell electricity to national power supply.
Hybrid inverters operate like On-Grid inverters and can store excess solar energy in a battery bank to sell it later or feed connected loads during a power cut.
Power inverters charge a battery bank from an AC power source to bridge power cuts in national grid and reduce fuel consumption.
IEC 61730 is the basic standard that describes the requirements for the safe operation of photovoltaic modules.
As photovoltaic modules are accessible and power generating devices, corresponding protection classes are specified.
The purpose of this classification is to classify electrical equipment by appropriate methods for protection against electric shock.
In the IEC 61730 1:2004 standard, the protection classes were previously specified as class A, B, C.
However, with the update in June 2018 of the IEC 61730-1:2018 standard, it must be specified as Class 0, II, III.
Basically, the classification is made according to the system voltage.
As can be seen in the table, the protection class, which was previously defined as class A, is now defined as class II.
Including solar modules, the protection class of electrical appliances, is class II.
A class II or double insulated electrical appliance includes in addition to the basic insulation, reinforced protective insulation.
As shown in the table, the symbols for the corresponding protection classes must be defined on the labels.
