1. Cut energy costs in half Self-generated solar power costs 8–12 Rp./kWh versus 20–30 Rp. from the grid. At 500,000 kWh annual consumption, that is CHF 50,000–110,000 in untapped savings every year.
2. Strong investment returns Amortisation in 4–6 years, return on equity of 8–15%, and planning security for 25+ years, without exposure to volatile grid price increases.
3. Up to 30% subsidised The federal one-off subsidy covers up to 30% of your investment. A 500 kWp system costs CHF 600,000–900,000 gross, yielding a net investment with bankable economics.
4. Turnkey, manufacturer-independent Installations from 100 kWp to the MWp range with manufacturer-independent planning and one point of contact from site analysis through to ongoing monitoring.
5. 150+ proven installations 50 MWp installed since 2020, with Balteschwiler (3,092 kWp) and BACHMANN GROUP (2,195 kWp, 96% self-consumption) as documented benchmarks.

Your business purchases electricity at 20–30 Rp./kWh from the grid. Self-generated solar power costs 8–12 Rp./kWh — less than half. You pay this difference every day your roof surfaces remain unused. And with each year that grid prices rise, the gap widens further.

As an owner-managed specialist for industrial energy systems, we deliver your project turnkey — from site analysis through engineering and construction to commissioning and ongoing monitoring. Our installations range from 100 kWp up to the MWp range. And because we have no obligation to any manufacturer, we recommend the components that make economic sense for your installation — not for our supplier contracts.

Case studies: What our clients achieve

No theoretical promises — these results are documented in our commissioning protocols:

• Balteschwiler AG — 3,092 kWp, Laufenburg: Largest rooftop PV installation in Canton Aargau. The timber business has been energy self-sufficient since commissioning and feeds 1.9 GWh of surplus electricity into the public grid annually.
• BACHMANN GROUP — 2,195 kWp, Hochdorf: 96% self-consumption thanks to 24/7 production operations. 75% of modules are glass-free lightweight modules — realised on 9 roofs with limited load-bearing capacity where standard solutions were not possible.
• Kuny AG — 633 kWp, Küttigen: Amortisation in approximately 5 years. Extended in 2026 with a 522 kWh battery storage system — for peak shaving, higher self-consumption, and participation in ancillary services.

What does this mean for a typical industrial project? A 500 kWp installation produces approximately 500 MWh of solar electricity per year. At a self-consumption rate of 60–70% and current grid electricity prices, this yields an annual cost advantage in the high five-figure range — with a net investment that typically amortises within 4–6 years after deducting the one-off subsidy. After that, you produce your electricity for 8–12 Rp./kWh — while grid prices continue to rise.

Is your site suitable?

If two or more of these points apply to your situation, a potential check is worthwhile:

• Roof area from 500 m² — flat roof, trapezoidal sheet, corrugated roof, or facade — we cover all common substrates
• Annual electricity consumption from 200,000 kWh — the higher the daily consumption, the greater the self-consumption and the faster the amortisation
• Rising energy costs are straining your margins — self-generated electricity creates plannable costs for 25+ years
• Logistics or industrial roofs with limited load-bearing capacity — our lightweight solutions realise PV even where standard modules are too heavy
• Electrification of vehicle fleet or operational processes planned — PV as the foundation for charging infrastructure, battery storage, and intelligent energy management

Our offer: from analysis to ongoing operations

1

Potential check & feasibility study

Free potential check on roof suitability, capacity potential, and investment scale. Detailed feasibility study with yield modelling, investment calculation, and funding check — credited upon order placement.

• Roof suitability and capacity potential

Turnkey planning and realisation — one point of contact, no interface risk. We negotiate with authorities and funding bodies in your interest.

• Structural analysis and electrical planning
• Building permit and grid registration
• Construction management and commissioning
• Coordination with authorities and funding bodies

3

Service & monitoring

Round-the-clock remote monitoring with preventive maintenance intervals and rapid fault response — for maximum availability and sustained peak performance.

• 24/7 remote monitoring
• Preventive maintenance intervals
• Rapid fault response
• Performance reporting

4

Financing

Three models for different situations: own investment for maximum returns, leasing without equity capital, or contracting without investment risk.

• Own investment — all funding contributions directly
• Leasing — instalments below electricity cost savings
• Contracting — zero investment risk

5

Energy marketing & sector coupling

Market surplus energy via exchange access, PPA, or ZEV. PV is the starting point — storage, charging infrastructure, and energy management turn it into a comprehensive system.

• Exchange access and fixed offtake contracts (PPA)
• Self-consumption groups (ZEV)
• Integration with storage and charging infrastructure
• AI-based energy management

Solutions for your site

• Rooftop installations — flat roof, trapezoidal sheet, corrugated roof — including lightweight modules for roofs with limited load-bearing capacity. Up to 60% lighter than standard modules.
• Facades & vertical PV — disproportionately higher winter electricity production thanks to a low solar angle. Bifacial modules utilise reflection from snow and ambient light.
• Open-space installations — economies of scale at large capacities. Combined with rooftop installations and storage, a building block for energy self-sufficiency.

Frequently asked questions

How large does my roof need to be?

For an economically viable industrial installation, we recommend at least 500 m² of usable roof area, equivalent to approximately 100 kWp. Larger areas enable economies of scale — our projects extend to over 15,000 m² (Balteschwiler, 3,092 kWp). Roofs with limited load-bearing capacity can also be fitted using lightweight modules.

What does an industrial solar installation cost?

The investment depends on size, roof type, and complexity. For industrial systems from 100 kWp, the typical range is CHF 1,200–1,800 per kWp of installed capacity. A 500 kWp system therefore costs approximately CHF 600,000–900,000 before deducting the one-off subsidy (up to 30%). The exact price results from the feasibility study.

What happens to surplus electricity?

Three options: feed into the public grid (7–12 Rp./kWh), sale via a ZEV to tenants or neighbouring properties (15–22 Rp./kWh), or trading on the spot market via our active energy marketing (up to 40–80 Rp./kWh at peak times). A battery storage system additionally increases the more lucrative self-consumption.

How long does a project take from enquiry to commissioning?

Typically 6–12 months, depending on project size and permit process. The feasibility study is available after 2–4 weeks. Construction begins after the building permit is granted; realisation takes 4–12 weeks depending on scale. We coordinate the entire permit process with authorities and the grid operator.

What subsidies am I entitled to?

The federal one-off subsidy (via Pronovo) covers up to 30% of investment costs. Additional cantonal funding programmes apply depending on location (CHF 50,000–200,000+ per canton). For e-mobility and charging infrastructure, further BFE programmes offer up to 50% funding. We manage the entire funding process — no subsidy franc is lost.

What distinguishes you from a utility provider?

Utility providers sell you electricity — and offer PV as an add-on service, often tied to their own contracting models and supplier networks. We are engineers, not electricity vendors. Owner-managed, manufacturer-independent, with no lock-in to any grid operator. Three financing models instead of one. Response within 2 business days instead of utility-scale processes.
