Use your facade surfaces for solar power generation — we deliver vertical PV installations on a turnkey basis.

Peak winter electricity output Vertical PV produces disproportionately during the winter half-year, precisely when rooftop installations underperform due to snow and low sun angle and grid prices are at their highest.
Up to 25% bifacial bonus Glass-glass bifacial modules use both front and rear sides, with snow reflection increasing yield by up to 25% at no additional module cost and vertical mounting providing self-cleaning.
Three subsidy levels stackable GREIV federal funding up to 30%, winter electricity bonus from 2026, cantonal contributions up to CHF 300/kWp (Graubünden), and municipal funding can all be combined. We handle every application.
Unlock unused surfaces Facades, noise barriers, partition walls and fences become power sources without interfering with existing rooftop infrastructure. Example: 23 kWp on a 50 m partition wall yielded CHF 10,730 in subsidies.
Amortisation in 4–6 years The rooftop and facade combination measurably increases self-consumption and unlocks all three funding levels, with module lifespans exceeding 20 years.

Vertical photovoltaics unlocks surfaces that conventional rooftop installations cannot use: facades, noise barriers, fences and partition walls. The vertically or steeply inclined modules produce electricity reliably precisely when you need it most — during the winter months, when the sun is low. With the right combination of rooftop and facade installation, you measurably increase the economic viability of your entire energy infrastructure. We deliver your vertical PV installation on a turnkey basis — including complete subsidy processing at federal, cantonal and municipal level.

Why winter electricity is the decisive argument

Every winter half-year without a facade installation means purchasing the most expensive electricity of the year entirely from the grid. From October to March — when spot market prices are structurally higher and your rooftop installation delivers less due to inclination and snow cover — vertical PV compensates exactly for this gap. The modules are mounted vertically: snow slides off, and the low sun angle is not a disadvantage but an advantage.

In addition, the winter electricity bonus (in force from 1 January 2026) applies: installations from 100 kWp that produce more than 500 kWh per kW during the winter half-year receive an additional federal contribution via Pronovo. Vertical facade installations meet this threshold structurally — a direct economic advantage.

Rooftop only — or rooftop combined with facade?

The most intelligent solution is almost always the combination. Those who rely solely on rooftop installations cover summer demand well, but source the entire winter from the grid. Those who combine both achieve a more consistent annual supply, a higher self-consumption share, and benefit from combinable subsidies.

Rooftop installation only

Strong summer production, weak winter
Seasonally fluctuating self-consumption share
Federal EIV only — cantonal facade subsidies forfeited
Snow cover reduces winter yield
Available facade surfaces left unused

Rooftop + vertical PV combined

Year-round production with targeted winter compensation
Self-consumption rate noticeably increased — less grid purchase
Subsidies combinable on three levels (federal + cantonal + municipal)
Vertical modules: snow slides off, albedo effect increases yield
Facades, partition walls, noise barriers unlocked as power sources

11,332 kWh + CHF 10,730 subsidy

Example: 50 m partition wall, 23 kWp, Landquart — winter half-year

This calculation example shows what a single 50-metre partition wall can achieve: 23 kWp total capacity, 11,332 kWh of winter electricity (October to March) and subsidies of around CHF 10,730 — for this one surface alone in Landquart (GR). For larger operations with multiple facade sections, economic viability scales accordingly. Further references to turnkey implementation can be found in our project references.

Our implementation process

How we deliver your vertical PV installation

Site analysis & potential assessment

We assess your facades, partition walls and special surfaces for suitability, structural load capacity and shading — and determine the economic potential of each area.

Surface survey and yield modelling (including albedo simulation)
Structural assessment for mounting systems under wind and snow loads
Self-consumption analysis and winter electricity bonus eligibility check

Subsidy assessment & application

We assess all combinable subsidies at federal, cantonal and municipal level and handle the complete application process with Pronovo and cantonal authorities.

Federal funding: GREIV + integration bonus + winter electricity bonus
Cantonal special contributions (e.g. CHF 300/kWp in GR, CHF 140/m² in Basel-Stadt)
Municipal funding with winter electricity verification (e.g. CHF 150/kWp in Landquart)

Planning & engineering

We plan the entire installation — from module selection (bifacial, glass-glass) through the mounting system to inverter sizing and grid registration.

Manufacturer-independent component selection for maximum lifespan
Mounting system designed for high wind and snow loads
Complete grid registration and commissioning documentation

Turnkey implementation

We implement the installation on schedule and without operational disruption — including acceptance inspection, commissioning and handover of all subsidy documentation.

No operational disruption during installation
Acceptance protocol, commissioning and handover
Handover of all subsidy documentation and warranty certificates

Frequently asked questions

For whom is vertical PV most worthwhile?

Vertical PV is particularly worthwhile if you have high electricity demand in winter, limited or already occupied rooftop surfaces, or available special surfaces such as noise barriers and partition walls. Operations in alpine regions additionally benefit from the albedo effect through snow. Combining with an existing rooftop installation is almost always more economically viable than expanding the roof alone.

Does vertical PV produce enough electricity?

Slightly less than an optimally inclined rooftop installation in summer — but significantly more in winter. Precisely when other installations underperform due to low sun angles and snow cover, vertical PV produces at its highest level. Bifacial modules additionally use reflected ambient light on the rear side, achieving up to 25% additional yield at no additional cost.

Which subsidies can be combined?

Federal EIV (GREIV up to ~30% of system costs), cantonal special contributions (e.g. CHF 300/kWp in Graubünden, CHF 140/m² facade in Basel-Stadt), municipal funding with winter electricity verification, and the new winter electricity bonus from 2026 for installations from 100 kWp. We assess all levels for your location and handle all applications in full.

How much maintenance do vertical PV installations require?

Very little. The vertical mounting leads to self-cleaning: snow, leaves and dirt slide off. The glass-glass modules are designed for high wind and snow loads and achieve lifespans of 20+ years with performance warranty. On request, we also take on the ongoing service and operations of your installation.

Planning vertical PV as a strategic complement

Vertical photovoltaics is not a niche technology — it is the consistent answer to seasonal production gaps and unused facade surfaces. We assess your potential without obligation: facade surfaces, subsidy combinations and self-consumption optimisation in a single consultation. Request your quote.
