It depends on several factors. For quite an accurate calculation of the energy produced by location, orientation, tilt and maximum installed power please consult this calculator from the European Commission webpage: https://re.jrc.ec.europa.eu/pvg_tools/en/#PV
The factory standard size of the laminated photovoltaic glass is 1200 mm x 600 mm x 7.00 mm. It is possible to order other dimensions as well. The maximum size that can be ordered is 1200 mm × 3600 mm. The glass thickness increases along with the surface, according to the international standards. There is no lower limit in terms of the dimensions that can be ordered.
Any colors/tones (including colorless) can be ordered upon request. The colorless glass have a slightly higher energy producing efficiency than the colored ones. The degree of transparency can be ordered in between 2% – 90% for each chosen color.
There is no minimum individual order, but we can only send the production order to the manufacturer after a minimum quantity of 100 m2 has been accumulated (there may also be glasses of different sizes/colors/transparencies included in these 100 m2). If an individual order does not meet this condition, it will be placed on a waiting list until enough orders are registered.
The delivery time to the most suitable maritime port in Europe (from the moment of signing a firm contract and receiving the full payment into our bank accounts) is maximum 85 calendar days.
Our photovoltaic glass can be incorporated into a double-glazed unit, curtain wall or can be used as such in various structures. Integration into a double-glazed unit/curtain wall is done exactly the same as in the case of conventional glazing. It is recommended to install the photovoltaic glass only on fixed windows. On the mobile ones, on request, ordinary windows can be installed, but with the same aesthetic characteristics (dummy panels). After our photovoltaic glass is fixed into position, a qualified electrical integration team will install and interconnect the inverters/batteries/counters/etc., depending on the chosen system (on-grid/off-grid).
Our photovoltaic laminated toughened glass uses the CdTe thin film technology. The CdTe technology uses cadmium telluride in a thin semiconductor layer to convert sunlight into electricity. It has lower manufacturing costs compared to the crystalline silicon based technology – the most popular one to date. Moreover, the CdTe technology has the smallest carbon footprint of all current technologies used for the production of photovoltaic panels, as well as the shortest energy payback time (the time required by the panels to generate as much energy as went in to produce them).
Our non-transparent standard photovoltaic glass provides approximately the same power characteristics generated at the same costs as the conventional panels. The advantage of our opaque photovoltaic glass is that it can be easily integrated along with our photovoltaic windows due to their similar aesthetic and electrical characteristics (voltage/current).
The CdTe Layer is a material with a higher spectral response compared to the crystalline silicon and is having a better energy conversion performance under low light conditions (e.g. at sunrise or sunset). The temperature coefficient of the CdTe is approximately – 0.21% / °C, compared to the silicon cell which is about – 0.45% / °C. Therefore the CdTe have a superior performance of energy generation in warm climate (over 25°C). The CdTe technology have a much lower decrease rate in electricity production over time compared to the conventional silicon technology (after 25 years in use, the electricity production of the crystalline silicon panels decreases by about 20%, compared to the CdTe panels decrease rate of only 12.5%). Overall, photovoltaic panels that use CdTe thin film technology produce more electricity at the same installed power than other types of photovoltaic panels.
This technological revolution has the potential to change the field of global electricity production forever.
This means that windows, facades, tiles / roof windows generate electricity. BIPVs actually become part of the architecture, blending perfectly with the design of the building and eliminating the need for a separately mounted solar panel system.
In addition to photovoltaic windows, our company also sells and installs the following BIPV materials:

Modules are life cycle managed with a collection and recycling program, providing module owners with no cost, end-of-life take back, and recycling of the modules.
Example: a steel and glass office building with 30 floors and a glass area of 3300 m2 on each of the 4 sides (30m x 30m x 110m) would generate about 245 MWh / year. This amount of energy would be enough to fully charge (from 0% to 100%) 25 Dacia Spring daily. It should be mentioned that photovoltaic windows improve the thermal and sound insulation of buildings (they are laminated windows) and also reduce the solar radiation induced inside buildings depending on the color and the degree of transparency chosen (between 2% and 90%).
2. Vertical parts without windows can be wallpapered and thus power charging stations for electric vehicles. This eliminates the need to pull power cables throughout the city to power electric vehicles. Each car park could be equipped with batteries and chargers powered by BIPV photovoltaic systems.
Example: a 10-storey block lined on the side with opaque photovoltaic glass would produce approximately 68 MWh in a year. That would be the equivalent of 2537 full charges for the Dacia Spring (about 7 charges / day).
3. Glass railings on balconies can become electricity generators.

If the owner also closes his balcony using photovoltaic glass, the production of electricity will increase (it could cover, for example, the total consumption of a family of 4 people in summer and about 25% in winter).
4. They could be installed wherever there is an area exposed to sunlight and where transparency is needed / desired (eg industrial halls, warehouses, logistics hubs, greenhouses, animal savannahs, road sound insulation, bus stations, platforms, terraces, kiosks, etc.).
Example: a greenhouse of 10000 m2 (a square with a side of 100m), which would be covered using 70% transparent photovoltaic glass would produce about 440 MWh / year. With this amount of energy it would ensure its own consumption needs (pumps, lighting, etc.) and the surplus would be delivered to the system bringing substantial additional income.
Example: an industrial hall / warehouse of 10000 m2 that would be covered using photovoltaic glass of 60% transparency would produce about 670 MWh / year. Coupled with the fact that it will no longer be necessary to consume electricity with indoor lighting during the day, having natural light inside, practically such an industrial hall would also function as a photovoltaic park.
