Context

Organizations seeking to reduce energy costs and improve energy independence must ensure that their renewable energy investments are properly sized. An oversized solar system can lead to unnecessary capital expenditures, while an undersized system may limit energy savings and overall project profitability.

3E Ing. has completed several projects involving the design and optimal sizing of solar photovoltaic (PV) systems with battery energy storage systems (BESS) to identify the most effective technical and economic solutions for each application.

Project Scope

The objective of these projects was to determine the optimal balance between:

  • Solar photovoltaic generation capacity
  • Battery energy storage capacity
  • Current and future energy requirements
  • Self-consumption objectives
  • Operational constraints
  • Capital and operating costs

The goal was to develop reliable, scalable, and cost-effective energy solutions tailored to each site’s specific needs.

Energy Analysis and Modeling

Each study began with a detailed assessment of the site’s energy consumption profile and available solar resource.

Using advanced energy simulation tools, multiple scenarios were evaluated to:

  • Maximize renewable energy production
  • Reduce electricity purchases from the grid
  • Minimize fossil fuel consumption where applicable
  • Improve energy resilience
  • Optimize battery utilization and lifespan

Each scenario was assessed through a comprehensive technical and financial analysis to compare performance over the project’s entire lifecycle.

PV-BESS System Optimization

The analysis enabled simultaneous optimization of:

  • Installed solar PV capacity
  • Battery storage capacity
  • Power conversion equipment
  • Energy management strategy
  • Overall project costs

This approach ensures that every system component contributes effectively to achieving both operational and financial objectives.

Results

The studies enabled clients to:

  • Significantly increase renewable energy self-consumption
  • Reduce energy supply costs
  • Lower greenhouse gas emissions
  • Improve energy reliability and resilience
  • Confirm the technical and economic feasibility of proposed projects
  • Establish an optimized implementation roadmap

The recommended solutions provide the best balance between energy performance, operational reliability, and long-term financial return.
