The Project Summary Report is a client-facing proposal and financial evaluation deliverable generated by S-Miles Designer. It serves as a comprehensive sales tool that translates technical system configurations into clear financial returns, monthly generation insights, and ecological benefits.
1. Core Evaluation Capabilities
π° Comprehensive Financial Forecasting
The report automatically processes upfront hardware costs and regional utility parameters to calculate the long-term economic performance of the solar investment. It maps out multi-year savings, return metrics, and cumulative earnings across a standard 25-year system lifecycle.
π Dynamic Load & Generation Balancing
By mapping energy generation against household consumption profiles, the platform simulates real-world application scenarios. It categorizes power flow into distinct operating periods (e.g., self-consumption, grid feeding, and night-time consumption) to accurately estimate how much utility reliance will decrease.
π± Environmental Impact Quantification
The reporting engine converts estimated energy generation ($\text{MWh}$) into tangible ecological metrics. It calculates annual and lifetime greenhouse gas offsets, providing concrete numbers such as $CO_2$ reduction weight and equivalent tree planting figures to emphasize sustainability targets.
2. Report Content Sections
A standard Project Summary Report aggregates data across the following core evaluation blocks:
Section 1: System Overview & Core Metrics
This section delivers an immediate high-level summary of the proposed solar plant:
- Key Asset Performance: Highlights the total DC system size ($\text{kWp}$), estimated first-year savings, and projected 25-year cumulative financial earnings.
- Technical Benchmarks: Computes vital performance indices including the System Efficiency Index ($\text{kWh/kWp}$) and the net System Efficiency %.
- Hardware Aggregates: Displays the baseline bill of materials, noting the total number of PV modules and microinverters selected.
Section 2: Application Scenarios & Power Curves
Illustrates the daily interaction between system generation and home consumption:
- Operational States: Visually diagrams power flows during peak mid-day generation (surplus exported to the grid), partial coverage periods (utilizing solar while drawing remaining needs from the utility), and evening states (total grid dependence).
- 24-Hour Diurnal Power Profiles: Breaks down performance across all 12 months with overlaying line graphs mapping Consumption Power, Self-Consumption Power, and Generation Power from 00:00 to 23:00.
- Energy Shares: Uses clear ratio rings to show the exact breakdown of total generation versus overall home power use.
Section 3: Lifetime Utility Bill Savings
Provides an explicit long-term financial forecast:
- Bill Reductions: Visualizes the variance between the original utility cost projection and the optimized solar utility bill over a 25-year timeline.
- Inflation Compounding: factors in baseline energy prices and an annual utility rate growth percentage to illustrate how solar protects against rising energy inflation.
Section 4: Monthly Production & Financial Ledger
A granular, month-by-month data matrix that underpins the proposal:
- Visual Balance Chart: Combines bar graphs of generation and consumption with a monthly solar access path.
- Data Ledger: Lists precise monthly values for expected generation, self-consumption volume, utility bill savings ($\text{β¬}$), and grid-feed revenue ($\text{β¬}$).
Section 5: Long-Term Economic Analysis
Offers formal investment banking metrics to finalize project approvals:
- Investment Return Metrics: Computes the Net Present Value (NPV), Internal Rate of Return (IRR / Cash ROI), standard ROI %, and the exact asset Payback Period in years.
Section 6: Electrical Bill of Materials & Datasheets
Acts as an bridge to procurement by attaching full manufacturer specifications:
- Electrical Design Summary: Outlines component sorting, module specifications (tilt, orientation, model numbers), and microinverter branch pairings.
- Accessory BOM: Lists quantities for core cabling, trunk connectors, sealing caps, and termination tools.
- Integrated Datasheets: Automatically attaches official manufacturer specification sheets for the modules and microinverters, ensuring total transparency.
