A strategic framework for transitioning the UK's solar energy infrastructure to Vertical Bifacial Photovoltaic (VBPV) agrivoltaic systems. An evidence-based pathway for policymakers, regulators, planners, and industry stakeholders.
The window is narrow. With over 65 GW of ground-mounted solar in the UK planning pipeline (REPD October 2025), and projects receiving consent every week, technology choices are being locked in for 25–30 years. The time to act is now — not after the pipeline has been approved.
Establish updated planning guidelines that recognise VBPV agrivoltaics as distinct from conventional solar. Update the National Planning Policy Framework (NPPF) to explicitly support dual-use agricultural land for VBPV systems. Modify grid connection policies to prioritise demand-aligned generation profiles over raw capacity. This is the foundational step — without policy recognition, developers have no incentive to choose VBPV over the cheaper, familiar alternative.
Launch government-backed pilot projects across diverse UK agricultural regions — 5–10 sites, 1–5 MW each, covering a range of soil types, farming systems, and grid connection contexts. Establish monitoring frameworks measuring energy generation, agricultural productivity, biodiversity outcomes, and farmer satisfaction. Partner with universities (Lancaster, York, Sheffield) for independent validation. The UK currently lacks operational VBPV farm-scale data — this gap is the single biggest obstacle to wider adoption.
Introduce enhanced feed-in tariffs or Contract for Difference (CfD) strike prices that reflect VBPV's superior grid alignment value — its morning and evening generation peaks are worth more to the system than TMPV's midday output. Provide capital grants or low-interest loans for early adopters to bridge the ~16% panel cost premium. Develop agricultural subsidy modifications to support dual-use farming practices, recognising that VBPV farmers should not be penalised under Basic Payment Scheme successor schemes for having solar infrastructure on their land.
Develop British Standards (BS) for VBPV agrivoltaic installations covering structural requirements, electrical standards, and agricultural integration specifications. Create certification programmes for installers and system designers. Establish quality assurance frameworks for system components and performance guarantees. Standards provide the confidence framework that enables banks to finance and developers to build at scale.
Update Distribution Network Operator (DNO) planning assumptions to incorporate VBPV generation profiles — specifically their 46% higher grid hosting capacity and superior demand alignment. Revise National Grid's Future Energy Scenarios (FES) to model VBPV deployment pathways explicitly. Implement smart grid technologies that leverage VBPV's demand-aligned generation for grid balancing services, creating revenue streams that improve project economics further.
Establish a national database for VBPV system performance — energy output, agricultural productivity, biodiversity outcomes, and grid contribution. Implement quarterly policy reviews during the initial 3-year deployment phase. Create feedback mechanisms to adjust regulations based on empirical performance data. Set 5-year and 10-year deployment targets aligned with the UK's 45–47 GW solar target for 2030 (Solar Roadmap, June 2025).
The most common grounds for refusing solar farm applications is the loss of agricultural land. VBPV directly addresses this.
80–90% crop productivity with full machinery access. The food security objection — the most common grounds for refusal — is directly addressed by the technology design.
Vertical panels on a farm landscape read more like traditional field boundaries than the reflective sea of glass created by tilted panels. Agricultural activity continues visibly.
Farming communities are far more receptive to solar that preserves their agricultural identity. VBPV reduces the community opposition that drives expensive appeal processes.
Whether you are a developer, planner, farmer, researcher, or policymaker — the Harvesting the Sun Twice campaign welcomes engagement. The transition to VBPV requires collaboration across the entire sector.
