SOLAR ENERGY EXCEL DESCRIPTION

Solar PV EPC Financial Model is an Excel template (XLSX) available for immediate download upon purchase.

This financial model is designed to evaluate and forecast the operating and financial performance of a Solar Photovoltaic (PV) Engineering, Procurement, and Construction (EPC) business. The business scope includes the design, procurement, installation, and commissioning of turnkey solar PV projects across residential, commercial & industrial (C&I), and community or utility / distribution-scale applications.

The model captures project-driven revenue, solar module and balance-of-system procurement economics, civil and electrical installation costs, and monthly operating dynamics across configurable Solar PV market segments. It delivers a 5-year (60-month), forward-looking forecast, enabling decision-makers to assess scalability, revenue and cost trajectories, project-level margins, working capital requirements, and overall profitability.

Model Structure – Five Core Sections
1. Cover & Navigation
• Clear index with intuitive navigation across all schedules.
• Summary checks validating structural consistency and model integrity.
• Color coding for tabs and cells.

2. Input Assumptions
Key business drivers are consolidated into a centralized assumptions interface. To support granular monthly forecasting, assumptions related to the number of new Solar PV EPC contracts signed are embedded within the Revenue & Cost of Revenue tab.

Revenue Assumptions
The model supports industry-standard Solar PV EPC revenue frameworks, including:
• Customer Segments: Fully customizable segments (e.g., Residential, Commercial Solar and Community).
• Project Specifications: Volume drivers based on installed solar capacity (kW DC) and pricing per unit of capacity ($/W).
• Revenue Timing: Milestone-based billing and revenue recognition aligned with Solar EPC execution stages.

Direct Costs (COGS) & Procurement
• Hardware: Solar PV modules, inverters, mounting structures (fixed-tilt or trackers), combiner boxes, DC/AC cabling, transformers, and other balance-of-system (BOS) components.
• Execution Costs: Civil works, structural installation, electrical installation, testing, and commissioning.
• Soft Costs: Engineering and design, permitting, utility interconnection, grid studies, and contingency allowances.

SG&A & Operating Expenses
• Variable Costs: Sales commissions, dealer or referral fees, marketing and business development expenses.
• Fixed Costs: Management and staff payroll, office rent, software and SaaS tools, fleet costs, and general insurance.

Balance Sheet & Capital Structure Drivers
• CapEx: Tools and equipment, installation machinery, service vehicles, IT assets, and office infrastructure.
• Financing: Equity contributions, revolving working-capital facilities, and term-debt amortization schedules.

3. Output & Analytics
Dashboard
• Revenue trends segmented by Solar PV customer type.
• Gross profit, EBITDA, and net margin evolution.

Sources & Uses
• Uses: Start-up costs, pre-development expenses, project working capital, and capital expenditures.
• Sources: Equity injections and debt financing.

4. Integrated Financial Statements
• Profit & Loss Statement
• Cash Flow Statement
• Balance Sheet

5. Core Calculations
• Revenue and COGS recognition aligned with Solar PV EPC construction milestones.
• Staffing and payroll expense calculations.
• Debt schedules and capital expenditure roll-forwards.

Technical Specifications
• Fully transparent structure (no VBA or macros).
• Circular reference–free.
• Compatible with Excel 2021 or newer. Excel 2010–2019 Users- Certain calculations rely on array formulas and may require Ctrl + Shift + Enter for correct execution.

Validation & Control Checks
Built-in validation controls ensure model integrity:
• Green checkmarks (✓): Logic and calculations are consistent.
• Red indicators (✗): Inputs or assumptions require review.

Why This Model Is Well-Suited for Solar PV EPC Businesses
This model supports institutional-grade financial planning for Solar PV EPC contractors. It is purpose-built to address the project-based revenue profile, procurement-driven cost structure, milestone-based billing, and working-capital intensity inherent in Solar EPC businesses, while maintaining transparency across execution risk, cash-flow timing, and profitability drivers.
