Local context
Neuenburg sets the economic pace for this service.
Neuchâtel's utility landscape is mixed: Viteos covers the city and the lake area, Groupe E serves Val-de-Ruz and Val-de-Travers, and ENSA is active in the upper Jura. Feed-in tariffs and ZEV rules therefore differ noticeably by municipality – a per-location check is recommended.
In Canton Neuenburg, flat roofs on commercial buildings and multi-family homes represent the largest untapped solar area. Neuchâtel has adopted MuKEn principles into its cantonal energy law. New buildings must meet self-generation requirements, and heating replacements favour renewable systems. Heat pump combined with PV is the recommended standard.
Tax and subsidy logic
In the Canton of Neuchâtel, PV investments are 100% deductible as property maintenance – for both first-time installations and replacements. Costs can be spread over several tax periods if needed. Neuchâtel runs the «Programme d'encouragement pour l'énergie» with contributions to energy renovations. Since 1 March 2026 the canton also subsidises battery storage with a CHF 800 flat rate plus CHF 80 per kWh of storage capacity (max. 50 % of the investment, min. 3 kWh, max. 2 kWh per kW of installed PV capacity). There is no general cantonal bonus for PV itself. The main incentives are the Pronovo one-time payment, the full tax deduction, and feed-in tariffs from Viteos and Groupe E.
Permits and energy law
Roof-mounted systems on standard buildings in Neuchâtel require notification but no building permit. Permits are required for listed objects and systems in heritage protection zones (ISOS). The Commune (municipality) provides information on a case-by-case basis. Neuchâtel has adopted MuKEn principles into its cantonal energy law.

Market signal and location
Neuchâtel combines Jura-arc topography with pragmatic energy policy. With Viteos in the city of Neuchâtel, Groupe E in Val-de-Ruz and Val-de-Travers, and ENSA in the Jura highlands, the canton is shaped by three strong utilities. Feed-in tariffs are mid-range; self-consumption pays off especially well thanks to household electricity prices of 28–32 Rp./kWh. In the Canton of Neuchâtel, there is no general cantonal PV bonus. The main incentives are Pronovo, the full tax deduction, and the «Programme d'encouragement pour l'énergie», which supports energy renovations. Since 1 March 2026 a cantonal battery-storage contribution applies: a CHF 800 flat rate plus CHF 80 per kWh of storage capacity (max. 50 % of the investment, min. 3 kWh, max. 2 kWh per kW of PV). Viteos, Groupe E, and ENSA offer attractive feed-in tariffs.
