Ground-mount is a different sector.

Ground-mount
Solar farm development is a different proposition to commercial rooftop. The buyers are different, the grid is different, the planning regime is different, and the long-term asset management discipline once the farm is operating is different again.

Arc has built a specific consultancy line around it. We advise landowners considering leasing land to a developer. We advise developers structuring projects from land option through to consent. We advise infrastructure investors and lenders carrying out technical due diligence on operating or near-operating assets. We provide long-term operational asset management for owners of completed solar farms.

What connects the work is the same discipline as elsewhere in Arc: independent, fee-paid, written for the investment audience. The technical capability is built around the asset class, not adapted from other work.

Why Ground-Mount Solar Is Its Own Advisory Discipline

Commercial rooftop projects differ from solar farm developments in pretty much all significant commercial regards. The buyers for a ground-mount opportunity are largely landowners, developers, community energy organisations and infrastructure funds and, unlike for a rooftop project, typically do not include a facilities manager or Sustainability Manager. 

This is probably the reason why ground-mount solar advisors or solar farm consultants and landowners focus their activities as a different solar development consultancy service rather than adapting them from elsewhere.

Landowner Consultancy: Protecting Your Position Before You Sign a Lease

The Landowner solar developers UK are normally proposed with what's predominantly a developer's lease and option. An experienced and impartial landowner solar consultant UK review safeguards the landowner's business before signing, on elements including:

  • Independent examination of the developer's terms against those that would apply in the market on a commercial basis
  • Consideration of the nature of the option agreement itself, with due regard for the length of the option term and circumstances where an extension is provided.
  • Advice in relation to the solar farm lease agreement, and the manner of rent reviews and conditions relating to end of term restoration.
  • Identification of clauses that unduly transfer risk to the landowner.

Site & Portfolio Feasibility: What Needs Confirming Before Capital Is Committed

Before a large amount of investment is put in place, it is a common process to complete a solar farm feasibility analysis to assess whether the site is in fact capable of delivering your intended capacity. The work undertaken as part of this project includes;

  • Capacity testing against the physical limitations of the site
  • Grid capacity at the connection points
  • Mapping the planning constraints landscape, ecology, heritage, etc
  • Access assessment for construction vehicles and regular maintenance vehicles

On UK solar projects, the typical investor will engage an investment solar project consultant, to look at several potential investments. That same solar project consultant would use the exact same matrix as a due-diligence one, from one project to the next so the investor gets an apples to apples approach to how invested in how many and how all.

Grid Connection Management: The Highest-Risk Variable in Solar Farm Economics

Grid connection is often the single largest source of cost and time uncertainty in the development of a solar farm. As a solar farm grid connection consultant, Arc Renewables' service includes:

  • Direct liaison with appropriate DNO/NGED on behalf of developer/investor
  • Comparison of capacity offers against technical/commercial criteria 
  • Negotiation of connection costs if there is room for manoeuvre 
  • Risk of connection timeline against overall delivery programme

Technical Due Diligence: Independent Assessment for Lenders and Investors

A lender or infrastructure investor buying an operational (or soon-to-be operational)

solar farm will require UK solar farm technical due diligence carried out independently

of the project's original developer. This typically covers the following:

  • Comparison of technical performance against design parameters.
  • Evaluation of current O&M contract and contractor experience. 
  • Identification of deferred maintenance or latent defects impacting valuations.
  • Comparison of grid connection and planning conditions against actual requirements.

Operating Asset Management: Long-Term Oversight After the Farm Is Generating

After the solar farm has been built, over the lifecycle of 25+ years, continued monitoring is essential to ensure the solar farms are delivering on their predicted performance. Arc Renewables' solar farm asset management UK services include:

  • Close, continuous monitoring of solar farm operational performance against the modelled baseline projections.
  • Management of the operation & maintenance of the solar farm, including managing any appointed contractors.
  • Planning for and execution of lifecycle event activities, including repowering when the asset matures.
The infrastructure investor market for operating UK solar farms remains active. Arc's TDD and asset management work is structured around the institutional standards lenders and equity investors require.

Questions clients ask before engaging.

This analyses whether the solar farm is better commercially sited with storage in addition, encompassing grid constraint interaction, the opportunities to stack revenues and impacts on the current / envisaged grid connection contract.
It depends on the scale and age of the asset, but a loan grade and investor grade review will normally be timed and scoped back to the overall transaction deadline at commencement.
Both. Arc Renewables can assess an existing O&M arrangement and its contractor as part of due diligence and ongoing asset management, and also on an ongoing basis as the consultant where there is no contract in existence and a service requirement exists.
Feasibility is undertaken prior to building a project and determines if the site is capable of achieving the intended capacity. Technical due diligence is performed for a lender or investor that is considering acquiring an operational or about-to-be-operational asset.
This may vary with the nature of the engagement and should be discussed with Arc Renewables directly at the time of enquiry, as Arc Renewables' fee structure is applied per engagement.
Basically, the system registry and the certification procedure are identical. In this particular instance, however, instead of buying the certificates, the farm generates its own, and therefore, the strategic consideration moves from what certificate should I buy and more specifically how should I retire, sell, or allocate what is available:
