Architectural power glass for the facade market in Switzerland and Europe. It costs about the same as premium cladding, then generates power for 25 years and more.
The best fit is not a new build. It is re-cladding the big blank facades of buildings that already stand: silos and grain elevators, warehouses and logistics halls, parking decks and industrial towers.
A retrofit re-clad skips the multi-year design and construction cycle of a new build, so a first real project is realistic in months.
Tall, standalone industrial buildings offer huge uninterrupted south and west faces, the conditions facade power glass actually needs and rarely finds in a city.
No long design phase and no aesthetic committee. It is a re-cladding and return-on-investment decision, made by the building owner, which shortens the sale.
Large industrial facades often need re-cladding anyway, for corrosion, insulation or appearance, so the generation is the return on spend the owner was making regardless.
Helvara Power Glass is a building-integrated photovoltaic glass. It replaces conventional cladding and generates electricity across the whole surface of a building.
For a facade you already intend to clad in stone, terracotta, fibre-cement or spandrel glass, Helvara Power Glass is cost-competitive as cladding before a single kilowatt-hour is counted.
A premium architectural surface that pays for itself. 25 years and more of on-site generation, on cladding you were going to install anyway.
It works where buildings actually expose glass: vertical, often shaded, often hot. The product is designed around that.
Helvara Power Glass is designed to produce more energy on the surfaces a European building actually offers, not to chase a laboratory efficiency figure.
A temperature coefficient of roughly −0.30 %/°C, around a third less power lost per degree of heat than crystalline silicon. A measurable yield advantage on hot, unventilated facades.
Stronger output in diffuse and low-angle light, overcast days, non-south orientations and winter sun, which is what a Central-European facade receives most of the year.
The most homogeneous deep-black finish of any power-generating glass, no visible cell grid or busbars. The flat architectural surface specifiers ask for, at facade scale.
Competitive per square metre with premium stone and terracotta as a ventilated rainscreen. The electricity is the return on cost you were already committed to.

Helvara Power Glass is manufactured by CNBM, a Fortune Global 500 building-materials group and a world leader in thin-film photovoltaic glass, backed by decades of glass-technology engineering.
That scale is why Helvara Power Glass delivers the largest single-panel power glass in its category with the manufacturing consistency a facade programme demands, panel after panel, floor after floor.
Selected thin-film power-glass facades delivered across Europe.
A good product is only half the job. The other half is delivering it to the rules in Switzerland and Europe, with the assurances specifiers expect.
Evaluated against Europe's leading building-integrated PV research and test programme, so datasheet figures are figures you can specify with.
Documented to the Swiss technical-acceptance framework (SIA) and the relevant IEC and construction-product standards for the European market.
A committed end-of-life take-back and recycling programme in Europe, the responsible-sourcing assurance an ESG-conscious client expects, ready before they ask.
The glass generates the power. We deliver the rest of the system.
Battery storage sized to the facade.
An energy-management layer.
Generation turned into carbon credits.
