The Canton of Glarus, as a mountain canton, strongly relies on the combination of hydropower and solar. Thanks to the ability to spread tax deductions over up to three periods and high yields on slopes, photovoltaics in Glarus is particularly worthwhile.
As a mountain canton, Glarus relies on the combination of hydropower and solar for year-round renewable electricity supply. In narrow valleys the horizon shades part of the day; we calculate the yield of your roof individually.

Costs
Example: 5–10 kWp rooftop PV: CHF 14,500–23,300. Incl. 8.1% VAT, before incentives and tax deductions, without a battery. Calculated with the reference curve of the SFOE price survey (CHF 1,628 per kW plus CHF 5,278): the range reflects different system sizes. A market comparison, not a quote.
Roof renovation, structural reinforcement and replacement of the meter cabinet are not included. Roof access, electrical work and planning can change the price. Your specific quote follows the property assessment.
Costs with calculation and sourcesSizing
A typical household using around 4,000 kWh per year needs roughly 25 m² of module area (Swissolar, February 2024). As a starting figure, global irradiation in Canton Glarus is 1,094 kWh/m² per year (MeteoSwiss, Glarus station, 1991 to 2020 average). Whether that works on your roof in Glarus depends on orientation, pitch and shading, not on the floor plan.
Two federal bonuses explicitly do not apply to a single-family home: the winter electricity bonus requires at least 100 kW, and the tilt bonus at least 75 degrees of pitch. Neither applies to an ordinary pitched roof. Counting on them makes the business case look better than it is.
Clarify notification and permission before installationStorage
Battery storage earns its money through self-consumption. Electricity you use yourself saves not only the energy price but also grid fees and levies, which is why it is worth more than exported electricity. That is what decides whether a battery pays off.
Since 1 January 2025, an association for self-consumption (ZEV) may also use the existing connection lines. This makes apartment buildings and neighbourhood setups considerably cheaper, as no dedicated line is required. The grid operator depends on the municipality; in the Canton of Glarus they include TBGN.

Components by
Process
We clarify roof, electrical work, incentives and expansion path before you receive a quote. No site chaos, no wishful math.
Your key details are enough for a first, honest orientation. No appointment, no obligation.
We measure the roof by drone and clarify electrical work, regulations and the grid operator.
You see every line item individually, realistic ranges and sensible options such as storage or a wallbox.
Planning and installation by Vigorek. Electrical connection, grid registration and commissioning are handled by an electrical contractor licensed under the NIV. We coordinate schedules and documents.
From installation practice
Hooks and rails disappear under the modules. That is exactly where it is decided whether a system holds and the roof stays watertight. Marc Hammerschmidt has installed roofs like these himself and recorded the work on his phone.
Site diary · one tiled roof
Hooks come first. They sit under the tiles and later carry rails, modules, wind and snow.
Aluminium rails go onto the hooks. Where they end is decided in the plan, not on the roof.
By day four, the field is in place. When hooks and rails are right, the joints run straight by themselves.

The Founders
You know before signing who calculates your project and who builds it: two founders, one for engineering, one for finance. A solar system only works long-term when both fit together from the start.

CFA · former KPMG Senior Manager
Co-Founder · Strategy & Finance
Christian has been an independent management consultant and interim manager since 2015, most recently as Interim Treasury Manager at an energy storage manufacturer. Before that he was a Senior Manager at KPMG. He brings the financial structure: liquidity planning, transparent calculations and no project whose numbers don’t add up.

Co-Founder · Engineering & Planning
Marc handles the technical side: planning, structural analysis and system integration. He has helped install systems on roofs himself and plans so that nothing has to be improvised on the roof.
Clarity before commitment
Canton check
Single-family homes, agricultural buildings and smaller commercial roofs need different mounting systems. Before quoting, we review roof membrane, cable routing, inverter location and possible scaffolding logic.
Canton Glarus has its own rules for subsidies, permits and grid connection. We check them before quoting and record them in the project documentation.
Global irradiation in Canton Glarus: 1,094 kWh/m² per year (MeteoSwiss, Glarus station, 1991 to 2020 average).
Relevant grid operators in the canton: TBGN. Metering concept and registration are clarified before execution.
Normal notification procedure. In narrow alpine valleys with short sun windows, facade systems (75-90°) are preferred and often have simplified permits. Tourism infrastructure: hotels and mountain restaurants with special rules.
The GL-31 tilt-angle bonus pays CHF 250 per kWp, but only for system parts tilted at 75 degrees or more, capped at CHF 15,000. It requires a legally binding Pronovo funding decision including the tilt-angle bonus; the canton pays out only afterwards. A roof system with a conventional tilt does not qualify for this bonus, but can trigger the CHF 2,000 combination grant if a thermal solar system is built at the same time (from 2 kWp). TBGN: from 2026 quarterly market price, minimum 6 Rp./kWh guaranteed.

Core services
The key services, tailored directly to Glarus and the local requirements in your region.
Regional service
As a mountain canton, Glarus relies on combining hydropower and solar for year-round renewable supply. TBGN (Technische Betriebe Glarus Nord) operates its own hydroelectric plants (~32 GWh) and takes in over 3.3 GWh/year from local PV systems – with enhanced compensation for systems ≤30 kVA. In narrow valleys the horizon shades part of the day; we calculate the yield of your roof individually.
Regional service
In Canton Glarus, flat roofs on commercial buildings and multi-family homes represent the largest untapped solar area. The Glarus energy law is based on MuKEn 2014. New buildings must cover part of their electricity demand from renewable sources. At the 2021 Landsgemeinde, the energy law was significantly tightened.

These guides answer the questions that come up most often before deciding on a solar installation.
Glarus offers two routes to a cantonal contribution towards a photovoltaic system: the GL-31 tilt-angle bonus of CHF 250 per kWp from 75 degrees, and the CHF 2,000 combination grant, which is only triggered together with a solar thermal system.
