Aanpassing welstandscriteria zonnepanelen en -collectoren Bijlages 2-4 – Solar Panel Regulations for Wassenaar
The Aanpassing welstandscriteria zonnepanelen en -collectoren is an official regulatory document issued by the Gemeente Wassenaar in the Netherlands. Updated on October 13, 2021, this document serves as a specialized amendment to the municipal building aesthetics code (Welstandsnota), specifically revising the standards established in 2010. It provides the legal and aesthetic framework for the installation of solar photovoltaic (PV) panels and solar thermal collectors on buildings and within gardens, aligning local policy with the Omgevingswet (Environment Act) and the Regionale Energie Strategie (RES).
The document's scope covers both residential and commercial properties, distinguishing between locations inside and outside the beschermd dorpsgezicht (protected village view) of Wassenaar. It details specific object criteria for small-scale installations, requirements for monuments, and conditions for ground-mounted systems in gardens. The regulatory framework is structured into three main components: Bijlage 2 (Criteria), Bijlage 3 (Explanatory Notes), and Bijlage 4 (Reports of stakeholder consultations), defining key terminology such as kleur op kleur (color matching) and geïntegreerde panelen (integrated roof tiles).
The following sections detail the technical requirements for placement, size thresholds for permit-free installations, and the specific aesthetic standards applied to historical and modern architecture within the municipality.
Criteria for Installations Outside Protected Areas
For properties located outside the designated beschermd dorpsgezicht, the regulations provide the highest degree of flexibility for sustainable energy generation.
- Roof placement: Solar panels are permitted on all roof surfaces without restriction, provided they follow the roof's slope.
- Outbuildings: Installations are allowed on the entire roof surface of sheds, garages, and carports.
- Garden installations: Limited systems are permitted in the rear yard (achtererf).
- Monuments: Placement is generally restricted to roof surfaces not visible from the public domain and requires advice from the Commissie Welstand en Cultureel Erfgoed.
Regulations Inside the Protected Village View
Within the beschermd dorpsgezicht, visibility from public spaces is the primary criterion for assessment. The municipality aims to minimize visual disruption to the historical landscape.
- Visibility: Panels are permitted on the roofs of main buildings and outbuildings provided they are not visible from the public street.
- Post-1970 buildings: Full coverage of roof surfaces is permitted, including street-facing sides, subject to aesthetic review.
- Pre-1970 buildings: Visible panels must follow a kleur op kleur (color-on-color) principle and be arranged in a continuous row along the roof edge (dakvoet).
- Integrated systems: The use of solar tiles or slates is permitted on older buildings to maintain the architectural profile.
Ground-Mounted Systems and Garden Installations
The document specifies rules for solar installations not placed on roofs, categorizing them under 'other structures' in the local zoning plans.
- Surface area: Standard installations are permitted between 10 m² and 12.5 m² depending on the specific zoning plan (Villawijken or Hofcamp).
- Exemptions: Larger installations up to 50 m² may be granted via a kruimelontheffing (minor exemption) if they do not conflict with local spatial quality.
- Height and clearance: The top of the installation must not exceed 3 meters in height. The bottom must be at least 60 cm above ground level to allow for undergrowth of shadow-tolerant plants.
- Clustering: For larger fields, panels must be clustered in groups of no more than three, with 20 cm gaps between rows.
Frequently Asked Questions
Are solar panels allowed on monuments in Wassenaar?
Yes, but they are generally restricted to roof surfaces not visible from public areas and require a weighted recommendation from the Commissie Welstand en Cultureel Erfgoed.
What is the maximum height for solar panels in a garden?
The maximum height for ground-mounted solar structures in a garden is 3 meters, with the lowest point at least 60 centimeters above the ground.
Can I fully cover a flat roof with solar panels?
Flat roofs may be fully covered if the inclination angle of the panels is less than 30 degrees and they are placed at a distance from the roof edge at least equal to their height.
Is a permit required for panels on the front of a house in a protected area?
Generally, panels visible from public areas in a protected village view require a permit and must meet specific aesthetic criteria like color matching and uniform placement.
What are the rules for serial housing built after 1970?
For serial housing (5 or more connected units), panels may be placed on street-facing roof surfaces if they are installed uniformly in clusters or continuous rows.
Are solar panels permitted as garden fences?
Solar panels may be used as property fences (erfafscheiding) in the side or rear yards, provided they comply with the local zoning plan heights.
