Invest only once the numbers stack up

Every investment decision made without a solid foundation costs you — through oversized systems, missed subsidies, or execution risks that only surface on site. Our preliminary study gives you the decision basis you need: technically sound, economically precise, delivered in 4–6 weeks.

Eliminate investment risk upfront A rigorous feasibility assessment before contract award means no surprises on site. 80% of preliminary studies lead to adjustments to the original system concept.
15–25% better economics Clients who start with a preliminary study achieve on average 15–25% better outcomes by avoiding oversizing and fully utilising available subsidies.
Precise ROI in 3 scenarios Typical amortisation 4–6 years. NPV and IRR are calculated for up to 3 expansion scenarios so you invest only in what makes financial sense.
Every subsidy captured Systematic review of GREIV one-off payment, cantonal programmes and tax benefits, with Pronovo pre-registration already prepared.
Decision basis in 4–6 weeks Modularly scalable study delivered in 4–6 weeks. Balteschwiler (3,092 kWp) and Hugelshofer (1,001 kWp) both started this way.

Why a preliminary study — and why now

Photovoltaic and electrification projects above 100 kWp are six- to seven-figure investments. Without a preliminary study, you make decisions based on initial proposals that optimise margins — not your return. Our clients who start with a preliminary study typically achieve 15–25% better economic outcomes, because oversizing is avoided and subsidies are fully utilised.

There is another factor: one-off payments (EIV) from the federal government are adjusted annually. Planning your system today locks in more favourable conditions than waiting a year. The preliminary study creates the documentation required for a priority subsidy application.

Our process

Whether a basic analysis or a comprehensive preliminary study — we tailor the scope modularly to your company. Each phase delivers actionable findings, even if you later narrow the scope.

Six phases — from analysis to decision

Needs analysis & goal definition

We analyse your energy consumption in detail and define measurable objectives: load profiles, peak loads, load-shifting potential and your target range for self-consumption and CO₂ reduction.

Load profile analysis (15-minute intervals)
10-year consumption forecast
Goal definition by financial and ESG criteria

Site survey & technical assessment

We assess your existing infrastructure on site — grid connection, transformer capacity, roof statics, electrical installations. You learn precisely what your current infrastructure permits and what must be adapted.

On-site survey with photographic documentation
Grid connection point and transformer review
Structural check for roof and façade

Feasibility analysis & scenarios

We develop up to 3 tailored expansion scenarios — from a basic system through to an integrated solution with storage, ZEV, and charging infrastructure. Each scenario is evaluated technically and economically.

Up to 3 expansion scenarios (basic/medium/maximum)
PV simulation with hourly yield forecast
Technology comparison: rooftop, façade, agri-PV

ROI calculation & subsidy review

We calculate amortisation period, NPV and IRR for each scenario and systematically review all relevant funding sources — federal one-off payments (EIV), cantonal programmes, and tax deductions.

ROI model with sensitivity analysis (electricity price ±20%)
EIV application preparation
Cantonal and municipal subsidy programmes

Environmental & risk analysis

We quantify the CO₂ footprint of the system and identify regulatory, technical, and financial risks — so there are no surprises during the execution phase.

CO₂ savings in tonnes/year (ESG-compliant documentation)
Regulatory hurdles (building permit, grid connection)
Risk register with mitigation measures

Technical design & decision recommendation

We produce initial technical designs with system layout and simulation — and deliver a clear, prioritised recommendation for which scenario we advise for your company and why.

Self-consumption/grid feed-in simulation
Decision paper with clear recommendation

From preliminary study to implementation

The result of the preliminary study is a decision basis — not a binding offer. You decide, based on the facts, which path to take. Clients such as Balteschwiler AG (3,092 kWp, the largest rooftop PV installation in Canton Aargau) and Hugelshofer Services AG (1,001 kWp, Europe’s largest e-truck charging park) started exactly this way.

If you wish to proceed after the preliminary study, we accompany you through Project Design & Construction, as general contractor, or via client representation — depending on your requirements. Start with a non-binding conversation.
