A premium solution

Zero compromises on quality to secure long lasting products.

Growing graph

Outstanding energy yields

More energy compared to mainstream alternatives.

Light bulb

Smart Design

Different module formats conceived to outperform in each application.


Minimum energy losses

Extremely low conversion losses caused by overheating and elevated operating temperatures.

Shield with check in the centre

Protection over time

No electrical degradation caused by PID, LID or LeTID and market-leading mechanical resistance.

3SUN CORE-H® solar cells

The very best in solar energy conversion and technology development.

3SUN CORE-H® technology converts the highest amount of sunlight, elevating solar energy beyond the limits of the PERC, PERT and TOPCon.

Nothing is left to chance with our solar cells.

TCO - Transparent conductive coating

Innovative transparent and conductive anti-reflection coating, optimized to improve sunlight transmission and convey the generated electrical charges towards the metal conducting grid.

Amorphous silicon (p/n a-Si:H)

P and N amorphous silicon layers applied to maximize the conversion of energy and the conduction of electrical charges by preventing losses and avoiding recombination at the interfaces.

N-type crystalline silicon

Ultra-thin, n-type silicon wafers allow excellent performance and stability while lowering the environmental impact.

Metal conducting grids

Narrow grid multi-busbar technology adopted to minimize resistive losses through improved collection and conduction of electrical charges.

Amorphous silicon (a-Si:H)

Micro-layers deposited to improve output voltage. Using a quantum tunnelling mechanism to create a perfect junction with the crystalline silicon, giving rise to the term “hetero-junction”.

Frequently asked questions

Our PV modules will be available on the market from 2024. Contact your installer of choice for a quote or send us an inquiry by filling out the contact form.

Our modules are marketed through a network of authorized distributors. Contact your trusted installer or send us an inquiry by filling out the contact form. 

With the current increase in energy costs, investing in solar allows you to reduce your energy consumption, making you independent for a major share of your energetic needs.

Our solar modules produce more energy for the same surface area than those with conventional technologies. They also provide more stable performance over time.

Generally, on rainy days, PV modules are self-cleaning, although we still recommend that you contact your installer for periodic checks.

PV modules are classified as normal electronic waste (WEEE) and therefore end-of-life management is done according to current national regulations.
