Taking over a business in the energy transition in Switzerland: opportunities and risks
Introduction
Switzerland has committed to an ambitious energy transition with the Energy Strategy 2050. This policy creates structural demand for businesses active in solar photovoltaics, thermal insulation, heat pumps and electric mobility.
For business buyers, these sectors represent concrete opportunities: sustained growth, public subsidies, and strong local demand. But they also involve specific risks related to regulatory changes, dependence on public aid and the speed of technological change.
This article analyses three key sub-sectors of the energy transition in Switzerland: solar photovoltaics, energy efficiency (insulation, heat pumps), and electric mobility. For each, we identify takeover opportunities, risks to anticipate, and the ideal buyer profile.
The objective: to give you a factual analysis framework to assess whether taking over an existing business in these areas matches your skills, resources and ambitions.
📌 Summary (TL;DR)
Solar photovoltaics offers the strongest growth, but requires technical expertise and vigilance on subsidies. Energy efficiency (insulation, heat pumps) combines stability and regular demand, with predictable margins. Electric mobility remains an emerging market with high potential but more risky.
Each sector requires a specific buyer profile and rigorous assessment of assets, contracts and regulatory dependencies.

The Swiss energy transition: a favourable context for takeovers
The Energy Strategy 2050 sets the framework: phasing out nuclear power, developing renewables, improving efficiency. Federal and cantonal subsidies massively support the sector.
The Swiss energy transition market represents several billion francs of annual investment. Hundreds of SMEs active in solar, insulation or electric mobility are looking for buyers.
This is a strategic moment to acquire a business positioned in these growing segments. The most sought-after sectors by buyers in Switzerland in 2026 confirms this trend.
Solar photovoltaics: the most dynamic sector
Photovoltaics is experiencing exceptional growth in Switzerland. Demand far exceeds supply, driven by individuals, businesses and local authorities.
Businesses available for takeover include solar panel installers, design offices specialising in system sizing, and companies maintaining existing installations.
The market attracts many buyers thanks to its dynamism and media visibility. But beware of the sector's specific features.
Specific opportunities
Taking over a photovoltaic business offers several concrete advantages:
- Existing order book: visibility over several months of activity
- Recurring maintenance contracts: predictable revenue and customer loyalty
- Certifications in place: Swissolar, cantonal approvals already obtained
- Established supplier network: easier access to equipment
- Favourable subsidies: structural public support for the sector
These elements significantly reduce the start-up risk for the buyer.
Risks to anticipate
The photovoltaic sector presents specific risks to assess:
- Dependence on subsidies: possible political changes
- Rapid technological evolution: obsolescence of skills and equipment
- Intense competition: pressure on margins, multiplication of players
- Customer concentration: dependence on a few large contracts
- High working capital requirement: pre-financing of projects
Rigorous analysis is essential. Consult our guide Taking over a photovoltaic business: key evaluation criteria.
Ideal buyer profile
The buyer of a photovoltaic business must combine several skills:
- Technical skills: electricity, construction, system sizing
- Project management: site coordination, meeting deadlines
- Knowledge of standards: Swissolar certifications, OIBT, cantonal standards
- Construction network: contacts with architects, project owners, installers
Prior experience in construction or electrical work is a major asset for securing the takeover.
Energy efficiency: insulation, heat pumps and renovation
The energy efficiency sector includes thermal insulation companies, heat pump installers, and engineering offices specialising in energy renovation.
The market benefits from strong structural demand: ageing building stock, strengthened legal obligations (cantonal MoPEC), ambitious climate targets.
The prospects are solid and sustainable, with less volatility than photovoltaics. A strategic segment for business takeovers.
Specific opportunities
Energy efficiency presents distinct advantages:
- Sustainable structural demand: continuous need for renovation of building stock
- Often better margins: less competitive pressure than in photovoltaics
- Technological stability: more gradual developments
- Possible synergies: complementarity with other construction trades
- Diversified clientele: individuals, businesses, public authorities
These characteristics offer a solid foundation for a successful takeover.
Risks to anticipate
The sector nevertheless involves specific challenges:
- Dependence on craft skills: difficulty recruiting qualified personnel
- Mandatory certifications: Cédral, Minergie, specific approvals
- Marked seasonality: reduced activity in winter
- Ten-year guarantees: responsibilities to take over on previous projects
- Established local competition: well-established historical players

Ideal buyer profile
The buyer of an energy efficiency business must possess:
- Construction or thermal experience: understanding of technical issues
- Technical team management: managing craftsmen, site coordination
- Knowledge of Swiss standards: MoPEC, SIA, quality certifications
- BtoB and BtoC customer relations: adaptability to different stakeholders
A versatile profile, both technical and commercial, maximises the chances of success.
Electric mobility: charging stations and infrastructure
The electric mobility market is gradually taking shape. It includes charging station installers, charging network operators, and maintenance and operation service providers.
The growth of the Swiss electric vehicle fleet generates increasing demand for charging infrastructure, both for individuals and for businesses and local authorities.
This is an emerging sector, with significant opportunities but also uncertainties to consider carefully.
Specific opportunities
Electric mobility offers interesting prospects:
- Fast-growing market: rapid expansion of the electric vehicle fleet
- Recurring contracts: maintenance, operation, network management
- Possible diversification: company fleets, condominiums, public car parks
- Moderate barriers to entry: market still accessible for new players
The development potential remains considerable, particularly in French-speaking Switzerland and in urban areas.
Risks to anticipate
The sector presents risks related to its youth:
- Immature market: fragmentation, absence of established standards
- Rapid technological evolution: risk of equipment obsolescence
- Competition from large groups: national and international energy companies
- Business models being tested: profitability still uncertain
- Regulatory dependence: evolution of standards and obligations
A medium-term strategic vision is essential to navigate these uncertainties.
Ideal buyer profile
The buyer of an electric mobility business must combine:
- Electrical and IT skills: installation, management software, connectivity
- Strategic vision: ability to anticipate market developments
- B2B services experience: managing contracts with businesses and local authorities
- Appetite for innovation: sector in rapid transformation
An entrepreneurial and adaptable profile is particularly sought after in this emerging segment.
Valuing an energy transition business: specific features
Valuing an energy transition business requires particular attention to several points:
- Quality of order book: recurrence, customer diversification
- Value of certifications: approvals, technical qualifications
- Dependence on subsidies: share of turnover linked to public aid
- Technical teams: loyalty, skills, recruitment capacity
- Equipment fleet: condition, modernity, residual value
