For which businesses
Production halls and workshops, warehouses and logistics centres, retail outlets and supermarkets, guesthouses and hotels, offices, agricultural buildings, residential blocks with shared consumption. They all share the fact that consumption occurs during daylight hours and the roof is available. It pays off most where cooling or air conditioning is in use: the highest summer afternoon demand coincides with peak generation.
How we design a commercial solar power plant
- Data from the electricity meter. We will request from the distributor a 15-minute consumption profile for the last year and design the output so that most of the production remains in operation.
- Grid export. For businesses, we usually limit or exclude grid feed-in: the buyback price is low and zero overflows simplify connection. Overflow management is part of the design.
- Connection. We assess the main circuit breaker, reserved power and the condition of the substation. We submit the connection application with project documentation, including a utility network statement where required by the distributor.
- Structural integrity and roof. Roof covering load-bearing capacity, waterproofing layer composition, snow and wind zones. We choose between ballasted and anchored structures.
- Batteries For businesses, it makes sense to balance peak consumption, provide backup for critical circuits, or where operations run into the evening. It is not an automatic component.
- Monitoring production by chains, alarms on dropouts, access for your technical department and for service.
What is included in the offer
Panel layout on the roof, installed capacity, estimated monthly annual generation versus your consumption, share of direct consumption, itemised breakdown of components and works, schedule and list of administrative steps including who signs what. For subsidy programmes for businesses (OP TAK, Modernisation Fund), we will verify open calls and prepare the technical part of the application. Programmes 2026
Service and operation. After commissioning, we monitor production via the monitoring system and carry out an inspection after the first year. Power plant inspections are repeated at intervals according to the facility's operating regulations; we keep track of the dates for you.
Frequently Asked Questions for Companies
How large a photovoltaic system does the company need?
We design commercial power plants using 15-minute interval data from the electricity meter available to the distributor and based on the weekly operational schedule. The aim is to maximise direct consumption of generated power within the facility. We often limit grid feed-in for businesses because the buy-back price is low and the distributor may impose conditions on the connection.
Can the hall's flat roof support the panels?
The structural load from the panels ranges in tens of kilograms per square metre. For older halls and lightweight roofs, a statician assesses the load-bearing capacity and selects a light anchored structure instead of a ballasted one. This assessment is part of the preparation and not an additional item.
How long does connecting a commercial solar power plant take?
The connection application is submitted to the distributor along with the project documentation; the utility network statement usually arrives within a month. For higher output capacities, the distributor may require modifications to the connection or limitations on power feed-in. The entire process from enquiry to commissioning typically takes several months.
