Solar PV and Soil Association organic certification

Solar PV installation is fully compatible with Soil Association organic certification. The certifier explicitly supports on-farm renewable energy as compatible with organic principles. But certain considerations matter for organic certification continuity during install.

Soil Association certification continuity

The core point: rooftop solar PV installation on existing farm buildings doesn’t affect Soil Association organic certification. The buildings themselves are not ‘organic’ (only the land and produced food are); building modifications don’t trigger certification review.

Exceptions where certification engagement is needed:

• Land use change for ground-mount installations: if agricultural land is converted to ground-mount solar use, the certification status of that land changes. Soil Association should be notified and the land removed from organic certification (or alternative arrangements made if mixed-use).

• Manure handling changes near installation areas: if the project involves modifications to slurry storage or composting areas near the building, organic standards may be relevant.

• Soil disturbance during install: minor disturbance is typically not material; significant excavation (foundations, cable trenching) near organic land may need notification.

For standard rooftop PV installations on existing farm buildings: no certification action needed. We confirm specific requirements during the feasibility stage.

How solar supports organic positioning

Organic farming markets increasingly reference sustainability and decarbonisation. Solar PV provides:

• Documented Scope 2 emissions reduction for the operation
• Visible sustainability commitment for direct-to-consumer or farm-shop customers
• Audit-ready documentation for Soil Association Energy Plan compatibility
• Alignment with organic supplier audit programmes (Soil Association supplier programme; specific retailer organic programmes)

For organic supplier farms selling into supermarket organic ranges (Tesco Finest Organic, Sainsbury’s SO Organic, M&S Plan A Organic, Waitrose Duchy Organic), solar generation evidence supports the supplier-audit positioning.

Ground-mount considerations for organic land

For ground-mount installations on agricultural land, two scenarios:

Pure PV land (organic certification removed). Land transitions from agricultural organic to ground-mount PV. Soil Association certification removed from that specific parcel. Other organic land on the farm continues unchanged.

Agrivoltaic continued grazing. Sheep grazing under raised panels continues agricultural use. Land remains in agricultural use including the option of organic certification continuation. Soil Association supports this — discuss specifics with your certifier.

Pollinator or biodiversity stacking. SFI biodiversity actions (pollinator margins, mixed-species grassland) compatible with organic certification continuation. Combined ground-mount + SFI biodiversity stacking + continued organic certification possible on the same agricultural land.

Soil Association Energy Plan

Soil Association operates an Energy Plan supporting member farms in renewable energy installations. The plan provides:

• Guidance on organic-compatible renewable installations
• Connections to MCS-certified installers familiar with organic requirements
• Standardised documentation for certification continuity during install
• Network access to other Soil Association members who have completed similar projects

We support Soil Association member farms with Energy Plan-compliant documentation and certification-aware project delivery.

Practical recommendations

For Soil Association certified farms considering solar:

1. Confirm building scope is rooftop PV on existing farm buildings (no land use change)
2. Notify Soil Association of the installation intent (typically standard process; certification continuation usually straightforward)
3. Use MCS commercial-certified installer familiar with organic compatibility (we are)
4. Document the installation for inclusion in ongoing organic audit cycles
5. Consider SFI biodiversity action pairing where ground-mount is part of the project

For non-organic farms transitioning to organic certification: solar PV installation has no impact on the transition process. Both can proceed in parallel.
