PV + Battery Simulation Tool

Your intelligent energy advisor for smarter solar and battery sizing decisions

If you’re planning a solar PV and battery project, one question matters most:

“What is the most cost-effective and technically optimal combination of solar + battery for my site?”

The PV + Battery Simulation Tool was created to help commercial and industrial energy users confidently answer that question – before spending a single penny on hardware. Built on real-world data, this browser-based simulation engine analyses 182 different PV and battery size combinations, covering 15 years of operation using actual battery degradation and round-trip efficiency data.

Who is this for?

This tool is tailored for:

• Energy consultants and design engineers
• Commercial and industrial building owners
• Facilities managers and sustainability leads
• Anyone working on grid-connected PV + battery feasibility studies

Note: Not designed for residential users due to unpredictable consumption patterns.

What you get

Once you upload your data, the tool provides:

• Key financial metrics:
  • Net Present Value (NPV)
  • Internal Rate of Return (IRR)
  • Payback time
  • System cost and projected energy savings
  • Battery-added value to NPV
  • Export ratio and LCOE (Levelised Cost of Electricity)
• Performance metrics:
  • PV production and battery throughput
  • Year 3 full “proof-of-concept” simulation (30-min resolution for energy imports/exports and SOC)
• Optimal sizing recommendation:
  • Highlights the best PV + battery combo based on ROI and technical fit

What do you need to start?

Just prepare a structured Excel file containing:

• 12 months of half-hourly electricity consumption
• Import/export tariffs
• Optional: Cost assumptions and metadata (or use our default values)

Then upload it and let the simulation engine do the hard work.

Why now?

The energy landscape is changing rapidly — with rising tariffs, grid constraints, and pressure to decarbonise, getting your battery and solar sizing right is more important than ever.

Battery storage systems are no longer just about backup — they’re strategic assets for load shifting, peak shaving, and protecting against grid outages.

But these systems aren’t cheap. Oversizing wastes investment. Undersizing means missed opportunity. Our tool helps you find the sweet spot.

What makes our tool different?

• Data-driven, not generic — Based on CALB lithium battery RTE + degradation models
• Engineer-friendly — Detailed results, not oversimplified
• Free to use — No fees, no install, just log in and run your simulation
• Built for decisions — Created to support business case preparation and investment approval
