Background
#Canton Glarus's 2026 energy funding programme contains no general capacity-based payment for photovoltaics, but two clearly delimited paths.
The first is the GL-31 photovoltaic tilt-angle bonus: CHF 250 per kilowatt-peak, up to a maximum of CHF 15,000. Only systems or system parts with a tilt of 75 degrees or more are funded, the eligible parts must total at least 2 kWp, and a legally binding Pronovo funding decision granting a one-time payment including the tilt-angle bonus is a mandatory prerequisite.
The cantonal bonus therefore builds on the federal decision and is paid out once that decision has been submitted. The second path is the combination grant for a solar thermal system plus photovoltaics: a flat CHF 2,000 that is expressly available only where funding measure M-08 — a solar thermal system on an existing building — is implemented at the same time.
This combination is not eligible on a new build, and the photovoltaic system must have at least 2 kWp. For owners in Glarus this yields a clear picture: a photovoltaic system with a conventional roof tilt receives a cantonal contribution only if a solar thermal system is built alongside it. Without that combination and without a steep tilt, the federal one-time payment is the only funding available.
General conditions apply to both paths: one application per building with its own EGID, filing before construction or installation begins, and a contribution rate of at most 50 percent of the measure-related total investment.

What counts for funding
#GL-31 is tied to the federal decision: a legally binding Pronovo decision granting a one-time payment including the tilt-angle bonus is required. Without that decision there is no cantonal bonus, even if the modules are steep enough.
System parts are expressly eligible too: what counts is a tilt of 75 degrees or more for the system or for individual parts of it, and those eligible parts must total at least 2 kWp.
The combination grant is not a stand-alone PV subsidy: the CHF 2,000 is only paid where measure M-08 is implemented at the same time on an existing building. No funding is available on a new build.
The 50 percent cap interacts with federal funding: together with other public contributions, the cantonal contribution may not exceed 50 percent of the investment costs for the individual project — under GL-31 that means together with the Pronovo one-time payment.
The funds are tax-relevant: funds paid out by the canton must be deducted under property maintenance in your tax return. The general funding conditions state this as an obligation, not a recommendation.
There is no entitlement: under Art. 38 para. 1 of the cantonal energy act there is in principle no right to funding. Where funds are tight the energy fund administration decides on priority, and if the budget is exhausted the confirmation or payment can be deferred to the following year.
The process in five steps
#Tick off for your project
Check which path applies at all
a tilt of 75 degrees or more leads to GL-31, a simultaneously planned solar thermal system to the combination grant. If neither applies, the Pronovo one-time payment is all that remains.
File the application before construction or installation begins via the cantonal application platform, with a separate application for each building with its own EGID. Assessment follows the rates and conditions in force at the time the complete application is filed.
Once the application has been filed, construction may begin at your own risk before the funding decision arrives. For the combination grant, the form and the quotation must be submitted with the application.
For GL-31, complete the one-time payment process with Pronovo and wait for the legally binding funding decision; the cantonal bonus is paid out once that decision has been submitted.
On completion, submit the required documents
for GL-31 the signed application, a copy of the Pronovo funding decision and a copy of the invoice; for the combination grant, the invoice and product description of the photovoltaic system attached to the solar thermal application.
