Available surfaces
A roof, site or carport may provide space for a solar power installation.
Possible solution
Solar panels
Local solar power creates value when generation, on-site use, feed-in and the other parts of the energy system are assessed together.
When is this relevant?
When local generation fits the energy architecture
Daytime consumption
Part of the energy demand coincides with periods of local generation.
Combined with assets
Generation can be aligned with charging, storage or other controllable processes.
Financial driver
From 2027, direct on-site use becomes more important
For Dutch businesses with a small-consumer connection using net metering, the scheme ends on 1 January 2027. Net metering does not apply to large-consumer connections; on-site use and exports must be assessed against the energy contract. Read more about on-site use and net metering at RVO (Dutch).
Direct on-site use
Solar electricity used by the business at the time it is generated does not first have to be exported and purchased again later.
Appropriate sizing
The demand profile and feed-in conditions become more important than simply maximising annual generation.
Combine generation intelligently
Control, charging or storage can help align demand and generation when the business case supports it.
Part of QontrolInsight
What do we investigate?
The number of panels alone says little. How the system fits the location, connection and demand profile determines the technical direction.
- Available surfaces and location-specific constraints
- Generation profile in relation to on-site consumption
- Connection, feed-in options and any limitations
- Integration with energy control, storage and charging infrastructure
- Technical design, protection and monitoring
- Management, maintenance and responsibilities after completion
In combination with
Generation is one of the energy flows
An integrated design looks not only at production, but also at when and where the electricity can be used.
In depth
Design for the situation, not simply for maximum capacity
A sound solar design connects the generation profile to on-site use, the location and the available room within the connection and feed-in agreement.
Assess on-site use and feed-in separately
Annual consumption alone is insufficient. Quarter-hourly data and an expected generation profile show when solar power can be used directly and when a surplus occurs.
- Coincidence of consumption and generation
- Weekends, seasons and future electrical loads
- Contractual room for consumption and feed-in
The roof and surroundings define the constraints
Structure, roof condition, shade, fire safety and cable routes must be assessed before a final system choice is made.
- Suitability and remaining service life of the roof
- Access for construction, inspection and maintenance
- Coordination with insurer, competent authority and grid operator where required
Spread and limit generation where appropriate
Orientation, panel fields and inverter capacity affect the timing and level of production. This can matter more than the highest possible annual yield.
- Align design with consumption and feed-in profiles
- Include electrical protection, distribution boards and metering points
- Prepare for active limitation or energy control
Continue monitoring performance and changes
Monitoring helps identify deviations in time. Maintenance and future connections to charging or storage should remain manageable from the design stage onward.
- Record commissioning values and responsibilities
- Organise monitoring, inspection and incident follow-up
- Assess expansions against the original system design
From analysis to management
How local generation becomes part of the whole
We first assess consumption, feed-in room, location and future plans. The installation, protection, metering plan and any control are then designed and implemented together, followed by monitoring after completion.
- QontrolInsightMap consumption data, available surfaces, connection, feed-in room and future assets.
- QontrolBuildDesign layout, capacities, protection, metering plan and phasing; coordinate delivery partners and verify completion.
- QontrolCareMonitor deviations, organise responsibilities and assess later expansions as part of the whole.
