Commercial Solar Finance
Commercial solar does not have to follow a one-size-fits-all funding model. Apache RES supports UK businesses with both direct capital investment and Power Purchase Agreement structures, helping organisations identify a route aligned with their property, energy profile and commercial objectives.
From initial feasibility and financial modelling through design, installation, grid connection and long-term monitoring, Apache RES provides an integrated approach to commercial solar delivery.
Making Commercial Solar Investment More Accessible
The financial case for commercial solar can be compelling, but the right way to fund a project depends on the organisation behind it. Some businesses want to invest directly, own the solar asset and retain the long-term financial benefits. Others want to reduce their exposure to upfront capital expenditure and explore a Power Purchase Agreement.
Apache RES assesses the technical and commercial characteristics of each opportunity before helping clients understand which route may be appropriate. Our approach brings together energy consumption, site suitability, system design, projected generation and commercial modelling so that funding decisions can be based on the characteristics of the actual project — rather than generic assumptions.

Commercial Solar Power Purchase Agreements
A Power Purchase Agreement provides an alternative route to commercial solar for organisations that want the benefits of on-site renewable electricity without necessarily funding the full installation through upfront capital expenditure.
What Is a Solar PPA?
A solar Power Purchase Agreement, commonly referred to as a PPA, is a commercial arrangement under which a solar installation can be funded through an agreed third-party structure and the site uses electricity generated by the system under agreed commercial terms. Rather than approaching the project solely as a capital purchase, the organisation enters into an agreement covering the electricity generated by the solar installation. The exact ownership, pricing, duration, responsibilities and commercial structure depend on the individual PPA agreement. Apache RES supports the development and delivery of suitable commercial solar opportunities through this model, subject to project assessment and commercial approval.
How a Commercial Solar PPA Works
01
Site Assessment
Apache RES reviews the property, energy consumption, roof or site characteristics and overall project suitability.
02
Solar & Energy Modelling
Indicative system size, expected solar generation and the site’s ability to consume the generated electricity are assessed.
03
Commercial Assessment
The project is reviewed to determine whether a PPA structure may be commercially viable.
04
PPA Terms
Where appropriate, commercial terms are developed covering electricity purchasing, agreement duration and project responsibilities.
05
Project Delivery
Following approval, the project progresses through design, procurement, installation, grid connection, commissioning and ongoing monitoring.
Why Businesses Consider a Solar PPA
Reduced Upfront Capital Requirement
A suitable PPA structure can reduce or potentially remove the requirement for the customer to fund the full solar installation cost upfront, depending on the agreed commercial structure.
On-Site Solar Generation
Generate electricity directly from the commercial property rather than relying entirely on grid-supplied electricity.
Long-Term Energy Strategy
A PPA can provide greater visibility over part of an organisation’s long-term electricity costs, subject to the terms of the agreement.
Preserve Capital
Capital that might otherwise have been committed to purchasing a solar installation can remain available for other business priorities.
ESG & Decarbonisation
On-site solar generation can support wider carbon-reduction, sustainability and ESG objectives.
End-to-End Project Delivery
Apache RES can support the project through feasibility, design, EPC installation, grid processes, commissioning and ongoing system performance.
CapEx vs PPA: Which Commercial Solar Model Is Right for Your Business?
Factor
CapEx
PPA
Upfront Investment
Customer funds the installation.
Upfront capital requirement may be significantly reduced depending on the structure.
System Ownership
Customer owns the system.
Ownership depends on the agreed PPA structure.
Energy Benefit
Customer benefits directly from electricity generated by its owned system.
Customer purchases or uses generated solar electricity under agreed commercial terms.
Long-Term Value
Designed to maximise the long-term benefit of direct system ownership.
Designed to provide access to solar generation without the same initial capital requirement.
Commercial Commitment
Upfront investment into an owned energy asset.
Longer-term commercial agreement, subject to negotiated terms.
Best Suited To
Organisations with available investment capital seeking asset ownership.
Organisations seeking an alternative route to commercial solar while preserving capital.
There is no universally superior option. The appropriate funding structure depends on factors including available capital, energy consumption, property ownership, investment objectives, project size and the commercial terms available. Apache RES can assess both routes as part of the initial project evaluation.
Is Your Site Suitable for PPA-Funded Solar?
Commercial solar PPAs are project-specific. A site’s suitability will depend on both technical and commercial factors, which is why Apache RES assesses the opportunity before recommending a funding route.
Commercial Energy Consumption
Sites with significant electricity consumption may offer stronger opportunities for on-site solar generation.
Daytime Electricity Demand
The ability to consume solar electricity while it is being generated can be an important part of project economics.
Available Roof or Site Area
The physical property must be capable of supporting an appropriately sized commercial solar installation.
Property Control
Ownership, lease structure and relevant property permissions need to be considered.
Project Scale
The size and economics of the proposed system influence the suitability of different finance structures.
Commercial Assessment
PPA projects remain subject to financial, technical and commercial assessment.
Commercial Solar Built Around the Numbers
Before a commercial solar project progresses, Apache RES assesses both its technical feasibility and commercial potential. Each opportunity is considered individually, taking into account electricity consumption, available roof or site area, projected solar generation, self-consumption potential, export potential, grid requirements, installation requirements and the proposed funding structure. This allows each project to be developed around the characteristics of the site rather than generic assumptions about savings or financial returns.
Commercial Solar Structured Around the Opportunity
Every commercial solar project is different. Apache RES assesses how energy generated by a site can be used most effectively, whether that is consumed on-site, exported, or structured through an appropriate commercial arrangement. For suitable projects, a PPA structure can allow Apache RES to develop the solar opportunity without the customer purchasing the system outright. The commercial structure can account for energy used at the site alongside generation that may be exported or supplied elsewhere. This creates a flexible approach where the value of a solar project is determined by the site, its energy profile, generation potential and agreed commercial structure — rather than a fixed payback target.
Commercial modelling built around each individual opportunity.
