Solar storage battery subsidy

New for 2026: dedicated subsidy for PV storage batteries up to CHF 130/kWh (Geneva, Neuchâtel). Boosts self-consumption as buyback tariffs are reduced.

Overview

Introduced in 2026 by several cantons (Geneva from 1 January via SIG, Neuchâtel from 1 March), this battery storage subsidy fills a gap: as solar buyback tariffs drop, local storage becomes the key to profitability.

Amount: CHF 130/kWh of capacity, for batteries up to 15 kWh (SIG Geneva). Eligibility: owners with existing or new photovoltaic systems. Cumulative with Pronovo one-time remuneration for a full PV + battery setup.

Strategic value: stronger self-consumption, independence from price hikes, less penalized feed-in, improved overall 20-year profitability.

Conditions

Existing or simultaneous PV installation, certified battery, maximum 15 kWh capacity for full rate, application before commissioning.

Frequently asked questions

Are there subsidies for photovoltaics?

Qu'est-ce que le Programme Bâtiments ?

Le Programme Bâtiments est le principal programme de subventions en Suisse, financé conjointement par la Confédération (taxe CO2) et les cantons. Il couvre l'isolation, le remplacement de chauffage, la ventilation et la rénovation globale. Chaque canton définit ses propres montants et conditions via ce programme harmonisé.

Quelle différence entre aide fédérale et cantonale ?

L'aide fédérale (via le Programme Bâtiments) fournit un montant de base identique dans toute la Suisse. L'aide cantonale complète ce montant avec un supplément qui varie selon les cantons. Certains cantons comme Genève ou Berne offrent des montants cantonaux très généreux, tandis que d'autres restent proches du minimum fédéral.
