Implementation of a photovoltaic installation with a capacity of 15.4kWp to power the facility Willa Poprad in Rytro

MWT modules full black, installation on the facade of the company building

Innovative modules using MWT (Metal Wrap Through) technology.

The most common solution in the manufacturing process of photovoltaic modules is to apply busbars by H-screen printing directly onto the silicon layer.

The cells that make up the modules are devoid of the traditional busbars on the front which increases the area without shading of the cells and the efficiency of the module higher by up to 5%.

In addition, the resistance generated by the welds between connected cells is reduced.

Elimination of the need for high-temperature solder, which increases the risk of micro-cracking.

Module efficiency of more than 20%

Carport with EV charger – charging station for electric cars (Tesla S, Nissan Leaf)

Terrace canopy/photovoltaic shed

We made a shed together with a terrace roofing with modules of the ‘glass-glass’ type (from German: “glas-glas”). The name comes from the double glazing, which is on the front as with traditional modules and also on the back instead of the traditional film. Among other things, this allows for greater strength and light transmission.

Advantages of SOLSUM glas-glas modules:

  1. Glass-glass technology, providing higher yields than standard modules due to the reflection effect (PERC)
  2. Elegant black design
  3. Manufactured in Germany
  4. 87% efficiency guarantee after 30 years
  5. 20-year product warranty
  6. Extended lifetime of bipv glas-glas modules by 10 years (up to 40 years) compared to standard modules 
  7. Increased mechanical strength due to double glazing (for snow, wind)

Photovoltaic installation on the roof of the house

Terrace roofing with photovoltaic panels, glass-glass bifacial premium modules

Photovoltaic installation on the production hall with a capacity of 2x40kWp, Lower Silesia province

The foundation of the installation was planned on a roof covered with a bitumen layer with mineral wool insulation with a structure similar to membrane-covered roofs, which excluded the possibility of attaching the supporting structure to the roof structure without losing the warranty. For this reason, a patented aerodynamic fastening system was used, which allows installation without damaging (perforating) the roof surface and without additional ballast. The system provides a negligible additional load per 1m2, which was a condition due to the statics and limited possibilities for additional loading of the roof.

Off-grid power system for the PTTK facility in the Karkonosze National Park

Our realization on one of the facilities of the PTTK Hostel in the Lower Silesian province in the Karkonosze National Park. The hostel is located in the hall below the Labský Peak on the edge of the Labský Kotel and at an altitude of 1168 m. We also provided an energy storage system there using lithium-ion technology, as the hostel is not connected to the grid. Thanks to the energy storage system combined with the photovoltaic installation, the shelter is energy independent.

Home PV installations on innovative modules using PERC technology

Innovative Rear Cell Passivation (PERC) Technology.

The photovoltaic modules are made using polycrystalline silicon technology, utilizing backside passivation technology, which improves module efficiency by increasing the cell’s solar absorption efficiency. The back passivation causes sunlight passing through the cell in the wavelength range of 1000 to 1180 nm to reflect off the back reflective layer directing photons back to the front wall of the cell. In this way, solar radiation in the case of cells with bottom passivation becomes an additional source of electricity.

The hostel is visited daily in the season by up to 6,000 people, so it was decided to maximize the use of energy from renewable sources and optimize its consumption. Photovoltaics supply the hostel with electricity, making it possible to dispense almost entirely with cumbersome diesel generators. Future expansion of the PV installation is planned. The installation is equipped with an energy monitoring and management system.

Photovoltaic installation on thatched roof

Photovoltaic shed

Photovoltaic installation on roof, Podhale

Glass-glass photovoltaic system, Mazowieckie province


Ideal for use as a cladding for gazebos, garages, carports, elevations and garden sheds. 30-year performance guarantee and 20-year product warranty.

Photovoltaic installation for water heating

Installation without inverter, connected through the controller directly to the heater. Thanks to a special controller, which tracks the optimal operating point of photovoltaic modules, it dynamically changes the load characteristics so that 100% of the current from the panels is used. Compared to collectors, the advantage of this solution is maintenance-free (no replacement of glycol, moving parts such as pumps) and much longer life – the warranty is 30 years for PV panels and a well-designed installation also provides water heating even in autumn and winter and overcast skies.
