Background
#Anyone planning a photovoltaic system in Schaffhausen should not only ask how much electricity the roof produces.
The decisive question is how much solar power can be used in the building, in a development or in a future local community. Self-consumption, classic ZEV, virtual ZEV and local electricity communities pursue similar aims but have different technical, contractual and grid-related requirements. Owners, property managers and businesses should therefore clarify the metering concept, loads, storage option, SH POWER process, feed-in and incentives early.

What drives the economics
#The simplest case is self-consumption in the same building: the PV system supplies existing loads directly and only surpluses go to the grid. EnergySchweiz describes self-consumption as using self-generated solar power without routing it through the grid; this is why daytime demand, heat pump, boiler, commercial loads and charging stations matter more than pure kWp maximisation.
A ZEV is mainly suitable when several parties use solar power together at the place of production. EnergySchweiz notes that a ZEV acts as one large customer towards the energy supplier and must organise internal metering. For landlords, condominium owners and commercial sites, this is a billing and responsibility topic, not just a technical module.
SH POWER communicates dedicated offers for self-consumption, vZEV and LEG in Schaffhausen. A virtual ZEV can enable shared use across several properties by calculation where the requirements are met. The local electricity community is a newer model for larger local associations. Both models must be checked against the current grid and metering process.
Battery storage and wallbox improve a project only if they fit the load profile. EnergySchweiz emphasises that self-consumption is economically relevant; a battery can cover night demand, but it does not fix poor roof planning, unclear billing or missing grid approval. Before investing, the load profile, load priorities and storage strategy must be defined.
Cantonal requirements and federal incentives are separate layers. The Schaffhausen energy ordinance contains requirements for self-generation and comprehensive roof renovations; Pronovo is responsible for photovoltaic one-time incentives. This does not create an automatic profitability guarantee, but requires clean alignment of obligation, incentive, use and grid connection.
The process in five steps
#Tick off for your project
Survey the building and loads
record roof area, existing electrical distribution, main connection, meter structure, daytime demand, heat pump, boiler, commercial load, planned wallboxes and tenants. Without this basis, self-consumption remains an estimate.
Choose the usage model before quoting
single-family home, apartment building, condominium, site or neighbourhood lead to different options. Only then can simple self-consumption, ZEV, vZEV or LEG be assessed as technically and organisationally viable.
Clarify SH POWER and grid process
connection, metering concept, smart metering, forms, feed-in, guarantees of origin and billing must fit before installation. For municipalities outside the SH POWER area, the responsible grid operator must be checked separately.
Calculate the technical variant
compare PV layout, inverter, battery storage, wallbox control, heat pump logic and energy management using real consumption data. The economic variant is often not the largest system, but the best combination of roof, demand and metering model.
Document incentives and obligations separately
Pronovo application, possible cantonal requirements for new buildings or comprehensive roof renovations, grid-operator documents and participant agreements belong in one project file. This keeps quote, permit path, grid connection and operation traceable.
