Use energy without storage!
Less carbon footprint!
Save the planet!
“Storage makes electricity more and more expensive, producing according to demand is the first commandment, but still exist a lot of potential in this field”
— Andreas Dreisiebner

Types of PVs
Vertical modules (90 tilted)
The productivity peak (Pmax) for 90-angle installations varies from 255 Wp (small size) to 390 Wp (standard size):
- More balanced profile throughout the year;
- Daily profile in the morning and evening.
Benefits of bifacial installations:
- Higher energy in winter;
- Easier maintenance;
- Less damage by hail;
- Last longer in time.
Butterfly modules (15-30 tilted)
The productivity peak (Pmax) for 15-30 angle installations varies from 330 Wp to 390 Wp (depending on the type of material):
- More productivity in summer;
- Daily profile mainly at lunchtime.
Benefits of butterfly installations:
- Low production in winter;
- Affected by snow and sand;
- Require more maintenance;
- Higher exposure to hail damage.
Instead of installing south-oriented PV systems with the well-known midday peak, a W/E vertical installations produce electricity in the morning and in the evening without creating a grid overload.

Benefits
Vertical Installations are solutions for:
- Producing energy at the right time;
- Saving money on energy storage;
- Safety for collective protection;
- Spreading urban farming;
- Boosting biodiversity;
- Reducing land use.
It is possible to combine food production and solar modules or use free space between modules for recreative purposes. Choose if you prefer to see more diversity of plants on your green roof or if you want to grow vegetables in your small garden on the roof. Decide what you want!
They can be utilised like safety installations on the roof for collective protection and they are much easier for maintenance.
They can save space in cities on advertising and billboards.
They are smart solutions that will reduce the use of land, energy, resources and the overall footprint of cities.
Drawbacks of vertical Installations:
- Lower energy profile throughout the year
Butterfly installations are solutions for:
- Higher energy yield in the same space throughout the year;
- Spreading urban farming if installed on higher levels;
- Protecting shade-loving plants from sun damage.
They have a higher energy profile throughout the year but don’t save a lot of space on the roof. Instead, they can be uplifted to free space on the ground for agricultural purposes and activity.
They are good at providing shadows for plants or crops, protecting them from excessive sun radiation. This helps spread biodiversity on the roof or produce higher crop yields in agriculture.
They can be cut from the grid when it is overloaded — negative price during the midtime.
Drawbacks of butterfly Installations:
- The energy profile is not evenly distributed throughout the day and year;
- The grid overload and negative productivity during peak shaving
We are developing tool for the mainternance that will save your money and keep your green roof constantly well-maintained!
Let’s build a better future together!
The second-generation of heterojunction silicon cells
We offer installations with heterojunction (HTJ) that are more productive than the first-generation monocrystalline silicon cells. Bifacial panels with HTJ have higher energy efficiency than the first-generation monocrystalline silicon cells.
Waffers with HTJ coverage attract more sun radiation and reach the energy efficiency up to 90-95%, instead of energy peak up to 70-75% without HTJ.
At the moment this technology is the best available innovation for the vertical bifacial PV installations.
