Why solar PV makes economic sense for this sector
UK aquaculture — trout, salmon, shellfish, recirculating aquaculture systems (RAS) for various species — operates substantial energy-intensive infrastructure. Solar PV is increasingly central to commercial aquaculture economics, particularly RAS systems with continuous pumping, oxygenation, and water-temperature control.
What this sector typically operates
UK aquaculture operations typically run: RAS pumping systems (continuous 24/7 electrical demand); aeration and oxygenation; water temperature management (heat pumps increasingly common); feed dispensing systems; processing and packing; cold storage and CA. Land-based RAS systems particularly electrical-intensive.
Sector-specific PV considerations
Aquaculture PV considerations: continuous 24/7 electrical baseload provides excellent PV self-consumption (typically 85-95% for RAS operations); roof area on hatchery and processing buildings often substantial; combined PV + heat pump for water heating increasingly the standard approach; supplier-audit positioning material for fish farms supplying major UK retailers; remote rural locations sometimes have capacity-constrained DNO connections requiring no-export design.
Typical system specification and economics
Typical UK aquaculture PV install: 50-500 kW. Cost £40,000-£425,000. Payback 4-6 years for RAS systems with strong baseload.

Common questions
Is solar economic for our specific sector?
Yes for most operations in this sector. Payback typically 4-6 years for RAS systems with strong baseload. Send us your half-hourly meter data and we deliver a free desk feasibility within 7 working days showing system-specific economics.
What grants apply to our sector?
100% Annual Investment Allowance is universal for incorporated farms. SFI 2025 biodiversity actions apply across all sectors. Smart Export Guarantee 8-15p/kWh on surplus generation. Welsh and Scottish farms have additional devolved schemes.
How long does install take?
From contract to commissioning: 4-7 months typical for rooftop PV; 6-9 months for combined re-roof + PV. We schedule works around the operation's busy seasons.
Can we install on older buildings with asbestos cement?
Yes — under a combined re-roof + PV programme. HSE-licensed asbestos removal followed by profiled steel re-cladding followed by PV. The PV business case typically pays for 60-100% of the re-roof over 25 years.
