How to Prepare a Commercial Solar Board Submission: A Step-by-Step Guide

A Commercial solar board submission isn't just a technical proposal, it is a business case that needs to stack up financially, manage risk, and align with where the business is heading.

It should translate engineering into commercial terms, showing how the project reduces costs, improves resilience, supports ESG and reporting, and delivers a return that holds up under scrutiny. The strongest submissions go beyond system specs.

They connect energy strategy to business performance and give decision-makers the confidence to approve.

For ESG and Sustainability Managers, the goal is to demonstrate that the project is viable, aligned, and low risk. Our step-by-step guide to preparing a board submission for a solar project outlines exactly what boards expect to see, and how to prepare for success. 

Commercial Solar Board Submission Checklist 

A strong board submission should include: 

1. Energy consumption profile

2. Strategic & ESG Rationale

3. System design & business impact

4. Financial model (Capex, IRR, payback)

5. Procurement & financing options

6. Risk assessment & mitigation

7. ESG reporting metrics

8. Delivery roadmap

Understanding a Commercial Solar Board Submission

A commercial solar board submission is a formal investment document used to secure approval from executive leadership or a board of directors for a solar and battery project. It goes far beyond a technical proposal, acting as a structured business case that aligns energy data, financial modelling, risk management, and ESG strategy into a single decision-making framework. 

For ESG and Sustainability Managers, this document is essential for building internal buy-in. It must clearly demonstrate that the project is not only technically viable but financially sound, strategically aligned, and operationally practical. In most organisations, it is the last step that determines whether a renewable energy initiative moves from concept to capital approval. 

Step 1: Build an Accurate Energy Profile

Every strong submission begins with real energy data.

At Smart, we like to use the past 12-24 months of your electricity data (interval data, bills, operational insights) to identify: 

• Peak demand periods
• Base load requirements
• Seasonal usage patterns
• Major energy users (e.g. HVAC, machinery) 

Where possible, we strengthen this with energy audits, sub-metering, and efficiency metrics (e.g. kWh per m²).

This ensures the system we design is correctly sized and aligned to your actual operations, not assumptions: a key requirement for board confidence. 

Step 2: Define the Strategic & ESG Case

Boards approve outcomes, not infrastructure.

Your submission will stand a better chance of success if it clearly explains why the project matters, such as:

• Reducing exposure to rising electricity prices
• Supporting net-zero or ESG targets
• Improving energy resilience with battery storage
• Enabling future initiatives like electrification or EV adoption

Position the project as a strategic investment, not a cost. This reframes solar from an expense into a driver of long-term value.

Step 3: Translate Technical Design into Business Outcomes

Technical detail is important, but it must be communicated in business terms.

Outline:

• System capacity and expected generation
• Site layout and integration
• Equipment selection (panels, inverters, battery systems)

Then connect this to outcomes:

• Lower energy costs
• Reduced peak demand charges
• Backup power and operational continuity

Boards do not need engineering depth, they need confidence in performance, reliability, and impact.

Step 4: Develop the Financial Model

This is the most heavily scrutinised section.

A strong financial model should include:

• Total capital cost (Capex)
• Operating & maintenance costs (O&M)
• Lifetime savings (typically over 25 years)
  

Key Metrics:

• Payback period (commonly 2-7 years in Australia) 
• Internal Rate of Return (IRR)
• Net Present Value (NPV) 

Also include value drivers such as:

• Government incentives (e.g. STCs)

• Tax depreciation benefits
• Protection against the electricity price increases

The objective is clear: demonstrate that the project delivers strong, predictable financial returns and has the numbers to back it up. 

Step 5: Evaluate Procurement & Financing Options

Boards need clarity on how the project will be funded. Smart offers multiple financing options that can draw on CapEx or OpEx budgets. These include: 

• Direct purchase: highest long-term return, fastest payback, full ownership
• Power Purchase Agreement (PPA): no upfront cost, predictable pricing, lower risk, includes O&M
• Leasing or hybrid models: flexible capital structures, quick turnaround, low doc options

Each option should outline: 

• Cash flow impact

• Ownership structure
  
• Risk allocation
  

This allows decision-makers to align the project with internal financial strategy.

Step 6: Identify Risk and Mitigation Strategies

A credible submission must show that risks are understood and controlled.

Key risks include:

• Grid connection delays

• structural or site limitations
• Construction disruption
• Regulatory approvals
• System performance variability

Mitigation measures may include: 

• Early engagement with network providers
• Engineering and structural assessments
• Tier 1 equipment with strong warranties
• Defined safety and construction plans

Boards do not expect zero risk; they expect managed risk. 

Step 7: Define ESG Reporting Metrics

For ESG-driven organisations – and let’s face it, these days most organisations are obliged to be - measurable outcomes are essential. 

Your submission should quantify: 

• Emissions reductions
• Energy cost savings
• Renewable energy generation

And outline how performance will be tracked through: 

• Monitoring systems such as our Smart Active subscription
• Regular reporting via Smart Zero or a similar carbon accounting reporting tool 
• Alignment with ESG frameworks and regulatory requirements, such as AASB
  

This ensures the project delivers transparent, ongoing value. 

Step 8: Present a Clear Delivery Plan

Finally, show how the project will be executed.

Include a structured roadmap: 

• Design & planning
• Procurement
• Construction
• Commissioning 

Support this with: 

• Timeline and key milestones
• Supplier credentials and experience
• Compliance and safety measures
• Ongoing maintenance strategy

This builds confidence that the project is deliverable, low-risk, and professionally managed. Smart can provide this information via our pre-sales engineering team.

Turning a Proposal into Approval

A successful commercial solar board submission brings together: 

• Energy data
• Strategic alignment
• Financial performance
• Risk management
• Delivery planning

When done well, it allows decision-makers to confidently approve a project that delivers both financial returns and long-term sustainability outcomes.

Approval comes down to one question: Is this the right strategic investment for the organisation?

Your submission should make that answer clear.
