Project questions

What organisations usually want to know.

What types of solar projects can Solixir support?

We can help explore land-based solar farms, commercial and industrial rooftops, public estates, private-wire projects and solar paired with battery storage.

How early should we involve Solixir?

Ideally at the earliest opportunity. Early review can identify critical questions around the site, demand, grid, planning, land rights, commercial structure and specialist requirements before unnecessary cost is committed.

Does Solixir carry out every technical service?

No. Major projects require appropriately qualified specialists. Solixir can help define the pathway, coordinate the commercial process and identify where engineering, planning, environmental, legal, grid and financial advisers are needed.

Can you assess whether our land or roof is suitable?

We can begin with a high-level opportunity review. A credible project will then require site-specific surveys, structural information, electricity data and specialist assessments.

How much land is needed for a solar farm?

There is no single minimum. The viable area depends on target capacity, site shape, topography, access, ecology, landscape constraints, grid opportunity and the commercial objective. We can help establish whether a site merits detailed assessment.

Can commercial rooftops support major solar installations?

Potentially. Suitability depends on usable roof area, condition, structure, loading, orientation, shading, fire strategy, access, electrical infrastructure and the building’s remaining life. Qualified structural and electrical assessment will be required.

What information is useful for an initial review?

The site address and boundary, approximate land or roof area, recent electricity data, ownership or lease position, known planning or grid history, project objectives and photographs or drawings are a useful starting point.

How long does a major solar project take?

Timelines vary significantly. A commercial rooftop may progress faster than a land-based solar farm, while grid, planning, land, surveys, procurement and finance can each affect the programme. We will set out an indicative pathway after the initial review.

Will the project need planning permission?

That depends on the location, scale and project type. Some installations may benefit from permitted-development rights, while others require a full application and supporting studies. A qualified planning adviser should confirm the correct route.

How does grid connection affect the project?

Grid capacity, connection cost, timing and export limitations can materially change a project. Early engagement with the relevant network operator and appropriately qualified specialists is therefore an important part of feasibility.

Can solar work where grid export is limited?

It may still be viable where a large proportion of generation can be used on site, export can be controlled, battery storage is appropriate, or another connection arrangement is available. This requires site-specific technical and commercial modelling.

Should battery storage be included?

Battery storage can help shift energy use, manage peaks, support an export limit or provide other services, but it adds cost and complexity. It should be included only where the load profile, operating strategy and economics support it.

How is a major solar project funded?

Possible structures include direct capital investment, asset finance, third-party ownership, leases and power-purchase arrangements. Availability and suitability depend on the organisation, project, counterparty and market conditions; independent financial and legal advice may be required.

What is a power purchase agreement?

A power purchase agreement, or PPA, is a contract under which electricity is sold to an offtaker on agreed terms. Contract length, pricing, indexation, credit risk, metering and responsibilities need careful legal and commercial review.

Can you estimate project costs and returns?

We can help develop an indicative business case using stated assumptions. Reliable decisions require current supplier pricing, site data, generation modelling, connection and development costs, operating costs, finance assumptions and appropriate sensitivity analysis.

Can you help us compare proposals?

Yes. Solixir can support a structured comparison of scope, responsibilities, assumptions, exclusions, risks, warranties, programme, projected performance and whole-life value.

Who maintains the system after construction?

The operating model should be agreed before procurement. It commonly covers monitoring, planned maintenance, vegetation or roof access, inspections, cleaning where justified, fault response, spare parts, warranties, insurance and performance reporting.

How do we begin?

Submit the consultation form with the location, approximate size, energy position and current project stage. We will arrange an initial conversation and recommend the sensible next step.

Answers are general guidance only. Every major project requires site-specific technical, planning, legal, environmental, grid and financial assessment.
