30-Year Excel Financial Forecast | Solar PV Production | Battery Storage | Debt & Investment Returns

Evaluate hybrid renewable energy investments through one integrated, fully editable Excel financial model.

The Solar + BESS Hybrid Project Finance Model by SheetworksStudio connects solar generation, battery energy storage, electricity revenues, project costs, financing and investment returns within a structured 30-year financial forecast.

Designed for renewable energy developers, independent power producers, infrastructure investors and project finance professionals, the model supports preliminary investment feasibility, financing analysis, commercial scenario evaluation and long-term project planning.

The complete package includes 15 integrated Excel worksheets, eight native executive dashboard charts, four financial scenarios and a professional 17-page PDF user guide.

📊 EXECUTIVE DASHBOARD & INVESTMENT PERFORMANCE

The Executive Dashboard provides a consolidated view of hybrid energy project economics.

Key investment indicators include:

  • Initial Project CAPEX
  • Project Internal Rate of Return (IRR)
  • Equity Internal Rate of Return (IRR)
  • Equity Net Present Value (NPV)
  • Minimum Active-Year Debt Service Coverage Ratio (DSCR)
  • Levelized Cost of Energy (LCOE)
  • Levelized Cost of Storage (LCOS)
  • Selected Financial Scenario and Model Status

Eight dynamically linked Excel charts visualize project revenue, electricity exports, operating profitability, debt balances and other relevant financial and technical trends.

Dashboard outputs are linked to the underlying model and respond to changes in assumptions.

⚡ SOLAR PV & BATTERY ENERGY MODELING

Solar PV Operations

Forecast annual electricity generation using configurable assumptions for:

  • Installed PV Capacity (MWp)
  • Annual Energy Yield
  • Technical Output Adjustment
  • Solar Panel Degradation
  • Direct Solar Electricity Exports
  • Solar Energy Allocated to Battery Charging
  • Grid Export Constraints
  • Energy Curtailment and Electricity Allocation

Battery Energy Storage System

Analyze battery storage performance using:

  • Rated BESS Power (MW)
  • Storage Duration (Hours)
  • Battery Energy Capacity (MWh)
  • Round-Trip Efficiency
  • Equivalent Daily Cycling
  • Solar and Grid Charging
  • Battery Capacity Degradation
  • Battery Replacement Timing
  • Replacement Investment Costs
  • Annual Battery Discharge

The ENERGY MODEL connects solar generation, battery charging, grid electricity purchases, battery discharge, conversion losses and total electricity exports.

The separate DISPATCH PROFILE illustrates a representative 24-hour operating concept.

Modeling convention: The financial forecast uses annual energy calculations. It does not perform chronological hourly battery dispatch optimization.

💰 THREE ELECTRICITY REVENUE COMPONENTS

1. Solar PPA Revenue

Forecast contracted electricity sales using an editable PPA allocation percentage and contracted electricity tariff.

2. Merchant Solar Revenue

Model non-contracted solar electricity exports using an editable merchant electricity price.

3. Battery Energy Sales

Estimate BESS discharge revenue using annual discharge volumes and electricity selling-price assumptions.

Grid electricity charging purchases are modeled separately as an operating cost.

Electricity price escalation and scenario assumptions allow users to examine how changes in commercial conditions affect long-term project performance.

🏗️ PROJECT CAPEX, OPEX & BATTERY REPLACEMENT

Capital Expenditure

The CAPEX BUILD worksheet includes 15 illustrative cost categories covering:

  • Solar Modules and Inverters
  • Solar Installation and Civil Works
  • Battery Equipment
  • Power Conversion Systems
  • Battery Installation and Energy Management
  • Grid Connection and Electrical Infrastructure
  • Permitting and Project Development
  • Construction-Related Professional Services
  • Contingencies and Other Project Costs

The workbook calculates initial project CAPEX and the corresponding initial debt and equity financing requirements.

Battery replacement expenditure is incorporated into the long-term investment forecast.

Operating Expenditure

The OPEX BUILD worksheet contains 15 illustrative operating cost categories.

The model connects fixed operating expenses, escalation assumptions, grid charging costs, depreciation and simplified taxation to annual project cash flows.

All cost assumptions should be replaced with independently validated project-specific information.

🏦 PROJECT DEBT, CASH FLOW & DSCR

The integrated financing schedule models the relationship between project investment, debt financing and investor cash flows.

Key capabilities include:

  • Editable Initial Debt Ratio
  • Loan Interest Rate
  • Financing Tenor
  • Annual Principal Repayment
  • Opening and Closing Debt Balances
  • Scheduled Debt Service
  • Cash Flow Available for Debt Service
  • Debt Service Coverage Ratio (DSCR)
  • Project and Equity Cash Flows

The model uses simplified straight-line principal amortization of initial project debt.

The FINANCIALS worksheet links operating revenues, electricity charging costs, OPEX, EBITDA, depreciation, financing expenses and simplified taxes with the cash flow calculations.

📈 INVESTMENT RETURNS, NPV, LCOE & LCOS

The RETURNS worksheet provides essential project finance indicators:

  • Project IRR
  • Equity IRR
  • Project NPV
  • Equity NPV
  • Minimum and Average Active-Year DSCR
  • Initial Project CAPEX
  • Initial Debt and Equity Funding
  • Lifetime Solar Electricity Exports
  • Lifetime Battery Electricity Exports
  • Total Project Revenue
  • Indicative Solar LCOE
  • Indicative Battery LCOS

The model evaluates discounted project and equity cash flows using configurable return and discount-rate assumptions.

LCOE and LCOS are calculated through documented simplified cost-allocation methods. They are intended for financial screening rather than independently certified energy cost benchmarking.

🔄 FOUR SCENARIOS & SENSITIVITY ANALYSIS

Evaluate alternative technical and commercial conditions through four selectable scenarios.

BASE CASE

Illustrative central project assumptions.

UPSIDE CASE

Higher solar yield, improved battery electricity-price spreads and more favorable battery durability.

DOWNSIDE CASE

Lower solar generation, weaker battery economics and less favorable storage performance.

CUSTOM CASE

User-defined scenario multipliers for project-specific analysis.

The SENSITIVITY worksheet provides a 5 × 5 revenue sensitivity table examining alternative solar-yield and battery-price factors.

This table is an illustrative first-year revenue stress test. For the integrated effect on project cash flows, debt coverage and investment returns, use the live scenario selector.

IMPORTANT LIMITATIONS & DISCLAIMER

This is an illustrative annual Solar PV and BESS financial screening model, not an hourly dispatch optimizer, certified technical engineering simulation, statutory three-statement accounting model or lender-approved financing model.

Project financing uses simplified straight-line amortization. Tax calculations, battery performance, solar dispatch allocation, LCOE and LCOS involve documented simplifying assumptions.

Financial results may indicate negative NPV, insufficient debt service coverage or other unfavorable investment outcomes. Passing internal model checks does not establish bankability or guarantee project profitability.

All project data, prices, financial assumptions and illustrative outputs are fictional.

Users are responsible for independently verifying project-specific technical inputs, electricity market assumptions, construction costs, financing terms, regulatory requirements and all financial calculations before making investment decisions.

This product does not constitute financial, investment, engineering, accounting, legal or tax advice.
