Independent, evidence-led assurance that your solar investment will perform as promised.
The Pre-Installation Audit provides organisations with independent, evidence-led, technical and performance analysis, and safety assurance before committing capital to a solar installation.
Designed to remove risk and uncertainty, the service validates design assumptions, generation forecasts and financial models, alongside a review of high-level safety considerations, to ensure proposed systems are technically robust, financially sound and aligned to site-specific energy requirements.
TEST acts as an independent expert. If you are considering installing solar, we can review the proposals you receive from potential installers or developers to confirm that system sizing, layout, technology selection and performance modelling, and high-level safety considerations are realistic and deliverable. Having this independent layer ensures you can be 100% certain in the decisions you are making – they are based on evidence and engineering reality, not sales-led projections.
At a Glance: We independently verify that proposed solar designs are right for your site, will perform as promised, are safe and worth the investment – before you commit.

Roof Structural
Survey
Our thorough assessment of the roof structure prevents the risk of collapse, which in turn provides reassurance not only to you as the installer but also to the system owner.

Energy Performance Review
Our background in energy consulting allows us to perform an energy performance review on-site, giving additional value to your clients.

Electrical infrastructure review
We conduct detailed assessments to identify optimal locations for all key electrical infrastructure, making your life easier when it’s time to install.

On-site design
review
Not everything can be seen from a remote design. We assess the site to make sure your design is viable, preventing any unwanted surprises.
The TEST Audit Framework
By identifying potential risks early, the audit enables organisations to invest with confidence, avoid costly design or installation issues, and maximise long-term performance from day one.

1. Site Structural & Data Review
We begin with a detailed site visit combining energy analysis and a roof structural survey (as needed)
- Review of current energy usage, load profiles and operational patterns
- Physical inspection of the proposed installation areas
- Structural assessment of the roof construction, load capacity and integrity
- Identification of any reinforcement requirements or constraints that could impact system design
This ensures the proposed solar installation is not only aligned to site demand, but structurally safe, compliant and viable before investment decisions are made.
2. System Requirements Definition
Using site insight, structural findings and energy data, we define the true system requirements for your site.
This includes appropriate sizing, layout configuration, mounting approach (informed by structural capacity), technology selection and high-level safety considerations — ensuring proposals reflect engineering reality rather than sales assumptions.


3. Independent Design & Proposal Review
Where installer or developer proposals exist, we independently assess and compare them against verified site and structural constraints.
We review:
- System sizing and layout
- Mounting methodology and structural loading assumptions
- Electrical infrastructure positioning
- Performance modelling and generation forecasts
- Compliance with structural and safety requirements
This provides assurance that designs are technically viable, structurally sound and deliverable in practice.
4. Performance & Financial Validation
We challenge generation projections and financial forecasts, including payback and ROI calculations.
By validating modelling assumptions against verified site conditions and structural realities, we confirm that projected outputs, savings and returns are credible and achievable.


5. Findings, Risk Mitigation & Investment Assurance
You receive a clear, evidence-led report outlining:
- Structural suitability and any reinforcement requirements
- Technical risks and mitigation actions
- Validated performance projections
- Financial analysis and sensitivity considerations
This removes uncertainty, prevents costly design-stage mistakes and enables confident, informed capital approval.
What Problems We Solve
Solar systems are over- or under-sized for actual site demand
Over optimistic promises regarding generation forecasts
Understanding and comparing installation proposals
Risk of poor long-term performance driven by incorrect design stage decisions
Lack of independent technical review to provide confidence before financial commitment
The Benefits for Organisations
Independent, evidence-led assurance before financial commitment
Reduced technical, financial and safety risk through early validation
Confidence that projected generation, savings and returns are achievable in practice
Improved long-term system performance by addressing risk at the design stage
Clear, evidence-led insight to support internal investment approval
