UK solar farm projects for investors

Rossair holds exclusive rights on selected UK solar farm sites and sells them to investors, funds and developers. Grid connection, planning consent and EPC delivery sit under one contractor. Project schedules are shared under NDA.

Contact us for details on the solar farm investments that are available.

A solar farm is a ground-mounted photovoltaic array built at utility scale to export electricity to the grid - typically 5 to 50 MWp across 25 to 150 acres, operating for 30 to 40 years under a long-term land lease. Rossair holds exclusive rights on a number of UK solar farm sites and sells those projects to investors, with EPC delivery and long-term operations available under the same contractor.

Solar farm projects for sale

We originate and hold exclusive rights on UK solar farm sites, then take them to market. Buyers acquire a project that has already been through the work that kills most schemes - land rights, grid position, and consent.

Projects are offered at different stages, and the stage drives both price and risk:

  • Early-stage - land agreement signed and a grid connection offer secured, planning not yet submitted
  • Consented - planning permission granted, grid connection held
  • Ready-to-build (RTB) - consent, grid connection and land rights all secured, construction can start
  • Build included - the project plus Rossair EPC delivery, transacted together

Capacity, region, grid position and consent status are shared under NDA. Contact us for the current schedule.

Who we sell to

Infrastructure funds, independent power producers, pension and institutional asset managers, and developers building out a UK portfolio. Some buyers want the project alone and appoint their own contractor. Others want the project and the build under one accountable name. We transact either way.

Rossair has been delivering UK building services since 1973. The same engineering discipline that runs our maintenance contracts runs our renewable energy delivery - named technical lead, documented handover, and a contractor still standing in twenty years to honour it.

Solar farm panels and system design

UK solar farms are built with Tier-1 monocrystalline modules, typically 550-700 W bifacial panels on fixed-tilt or single-axis tracker mounting. Tier 1 is BloombergNEF’s bankability ranking - it measures manufacturer financial stability and track record rather than raw efficiency, and it matters because a 25-30 year performance warranty is only worth what the manufacturer behind it is worth.

On a PV solar farm the module is rarely the constraint. Grid export capacity, land topography, shading and DNO reinforcement costs shape the design far more than panel choice. Rossair handles G99 applications and DNO approval in-house, which is where most utility-scale programmes lose time.

Battery storage is increasingly co-located with UK solar farms to firm output and capture price spreads. See BESS projects for grid-scale battery storage delivery.

Frequently asked

Questions about UK solar farm investment

What is a solar farm?
A solar farm is a ground-mounted array of photovoltaic (PV) panels built at utility scale to export electricity to the grid rather than to serve a single building. UK schemes typically run from 5 MWp to 50 MWp across 25-150 acres, connect via a dedicated DNO or transmission connection, and operate for 30-40 years under a long-term land lease. The terms "solar farm", "PV solar farm" and "solar park" all describe the same asset.
What solar farm projects does Rossair have available?
Rossair holds exclusive rights on a number of UK solar farm sites at varying stages of development, from early grid-offer stage through to consented and ready-to-build. Project specifics - capacity, region, grid position and consent status - are shared under NDA with qualified buyers. Contact us to receive the current schedule.
Who buys UK solar farm projects?
Typical buyers are infrastructure funds, independent power producers (IPPs), pension and institutional asset managers, and developers building out a UK portfolio. Some buyers acquire consented projects and appoint their own EPC contractor; others prefer to buy the project and the build together. Rossair can transact either way.
At what stage are solar farm projects usually sold?
UK solar farm projects change hands at four common points. Early-stage, where a land agreement and a grid connection offer are in place but planning is not submitted. Consented, where planning permission has been granted. Ready-to-build (RTB), where consent, grid connection and land rights are all secured and construction can start. And operational, where the asset is generating and sold as a yielding investment. Pricing and risk differ significantly at each stage.
What is the difference between a solar farm and commercial rooftop solar?
A solar farm is ground-mounted, utility-scale, and built primarily to export power to the grid as a revenue-generating asset. Commercial rooftop solar sits on an existing building and is sized against that building’s own electricity demand to cut grid consumption. Rossair delivers both, but they are different propositions: one is an investment, the other is an operating cost reduction.
What solar farm panels are used on UK utility-scale schemes?
UK solar farms are built almost exclusively with Tier-1 monocrystalline modules, usually 550-700 W bifacial panels on single-axis trackers or fixed-tilt mounting. Tier 1 is BloombergNEF’s bankability ranking - it reflects manufacturer financial stability and track record rather than raw efficiency, and it matters because the 25-30 year performance warranty is only as good as the company standing behind it. Module selection is a financing question as much as an engineering one.
Can Rossair build and maintain the solar farm after purchase?
Yes. Rossair delivers EPC (engineering, procurement and construction) and long-term operations and maintenance on UK renewable energy assets. Buyers who want the project and the delivery under one accountable contractor can transact both together. Buyers who prefer to appoint their own EPC contractor can acquire the project alone.
How does grid connection work for a UK solar farm?
A solar farm needs a connection offer from the relevant Distribution Network Operator or, for larger schemes, from the transmission operator. The application runs under G99 for generation above 3.68 kW per phase and confirms available export capacity plus any network reinforcement the scheme must fund. Grid position is often the single biggest driver of a project’s value - a secured connection at a strong grid point is what separates a viable scheme from a stranded one. Rossair handles G99 applications and DNO approval in-house.
