• Medium-sized systems (4.5–8 kWp): € 1,900 – € 2,500 per kWp.
• Larger systems (> 10 kWp): € 1,300 – € 1,800 per kWp.

6. Practical examples

Example 1 – Private individual
A double-executed aluminum solar carport with 16 black monocrystalline panels (6.4 kWp), string inverter, integrated LED lighting and 1 charging point: € 14,500 incl. installation.

Example 2 – Company location
A steel solar carport of 12 × 25 m with 96 panels (38.4 kWp), industrial foundation, three double charging stations and rainwater harvesting: € 58,000 excl. VAT.

Conclusion

The prices of solar carports vary greatly: from approximately € 6,000 for a small private version to € 60,000+ for large company systems. The costs depend on the number of panels, material choice, charging facilities and installation complexity. Because both architectural and electrotechnical expertise is required, it pays to use jeofferte.nl to compare multiple quotes on price, return and lifetime.

The installation of a solar carport in the Netherlands falls under both structural and electrotechnical regulations. Depending on the location, dimensions and design, an environmental permit may be required. In addition, the construction and solar energy systems must comply with technical standards and safety guidelines.

1. Environmental permit

1.1 Permit requirement

• Usually requires a permit because a solar carport is a permanent, free-standing structure with roofing and integrated solar panels.
• Permit requirement applies especially if:
• The carport is higher than 3.0 meters.
• The carport is placed in the front yard.
• The surface area is larger than the outbuildings permitted in the zoning plan.
• The carport is located within a protected city or village view.
• There is a monumental building or heritage.

1.2 Building without a permit

• Sometimes possible in the backyard as an outbuilding, provided the following conditions are met:
• Maximum height of 3.0 meters (with a flat roof).
• Within the permitted building percentage of the property.
• No exceeding of building boundaries in the zoning plan.
• Please note: even with permit-free construction, the construction must comply with the Building Decree.

2. Zoning plan and welfare criteria

• The zoning plan determines whether a carport is allowed on a plot at all.
• The municipal design review board can set requirements for:
• Material selection.
• Color and finish.
• Placement and integration into the environment.
• In some municipalities, special requirements apply to sustainable buildings, such as minimizing the reflection of PV panels.

3. Structural and technical standards

3.1 Construction

• Eurocode standards (NEN-EN 1990 to NEN-EN 1999) for structural safety.
• NEN-EN 1991 for wind and snow loads.
• Foundations must meet the requirements for load-bearing capacity and frost-free construction.

3.2 Solar energy system

• NEN 1010 for electrical installations.
• NEN 7250 for structural integration of solar panels.
• Installation must be carried out by a qualified installer (preferably with SCIOS Scope 12 certification for fire safety).

4. Electrical connection and network management

• Registration of the installation with the network operator is required via energieleveren.nl.
• For large installations (>3 × 80 A or >50 kWp), a network upgrade or separate connection may be necessary.
• Charging points for electric vehicles must comply with the NEN 3140 safety requirements.

5. Safety and fire regulations

• Municipalities may impose additional requirements on the fire resistance of materials.
• For public or company parking lots: escape routes, emergency lighting and fire extinguishing facilities required.
• Cable routes must be laid in such a way that they are protected against mechanical damage and weather influences.

6. Subsidies and tax regulations

Although not directly subject to permits, it is good to know that many municipalities and the RVO offer subsidies or tax benefits for solar carports, such as:

• ISDE subsidy for solar energy systems.
• MIA/VAMIL scheme for companies that invest in sustainable energy.
• Local incentive schemes (varies per municipality).

7. Practical examples

Example 1 – Private individual
A double-executed aluminum solar carport in the backyard of 2.9 m high and 5.5 m deep could be placed without a permit, provided it complies with the Building Decree and zoning plan.

Example 2 – Business location
A company wanted to place 20 solar carports in the parking lot. In addition to a building permit, a notification of the Environmental Management Activities Decree was required due to the capacity (>50 kWp) and the charging facilities.

Conclusion

For most solar carports, a building permit is required, especially for larger constructions, placement in the front yard or within protected areas. Even permit-free carports must comply with building and safety standards. Early consultation with the municipality and consulting the zoning plan prevents delays and extra costs. Via jeofferte.nl, installers can be compared who have experience with both the technical and the permit-related aspects of solar carports.
